The outcome of proximal humeral fractures in the elderly

Risk factors of poor mid-term shoulder functional outcomes of osteosynthesis using antegrade intramedullary nailing for humeral shaft fractures: a retrospective study with a minimum 5-year follow-up

BACKGROUND

Osteosynthesis using antegrade intramedullary nailing for humeral shaft fractures yields satisfactory bone union rates; however, it may adversely affect postoperative shoulder function. To date, factors affecting mid- or long-term shoulder functional outcomes following intramedullary nail fixation have not been clarified. In this study, we aimed to identify the risk factors for poor mid-term functional outcomes over 5 years postoperatively following antegrade intramedullary nail osteosynthesis for humeral shaft fractures.

METHODS

We retrospectively identified 33 patients who underwent surgery using an antegrade intramedullary nail for acute traumatic humeral shaft fractures and were followed up for at least 5 years postoperatively. We divided the patients into clinical failure and no clinical failure groups using an age- and sex-adjusted Constant score of 55 at the final follow-up as the cutoff value. We compared preoperative, perioperative, and postoperative factors between the two groups.

RESULTS

Five of the 33 patients had poor shoulder functional outcomes (adjusted Constant score < 55) at a mean follow-up of 7.5 years postoperatively. Proximal protrusion of the nail at the time of bone union (P = 0.004) and older age (P = 0.009) were significantly associated with clinical failure in the univariate analyses. Multivariate analysis showed that proximal protrusion of the nail (P = 0.031) was a risk factor for poor outcomes.

CONCLUSIONS

The findings of this study provide new information on predictive factors affecting mid-term outcomes following osteosynthesis using antegrade nails. Our results demonstrated that proximal protrusion of the nail was significantly associated with poor mid-term functional shoulder outcomes. Therefore, particularly in older adults, it is essential to place the proximal end of the intramedullary nail below the level of the articular cartilage.

Reverse Shoulder Arthroplasty versus Non-Operative Treatment of Three-Part and Four-Part Proximal Humerus Fractures in the Elderly Patient: A Pooled Analysis and Systematic Review

Background: The treatment of complex proximal humerus fractures in elderly patients is not yet fully elucidated. Of all treatment options, reverse shoulder arthroplasty (RSA) and non-operative treatment (NOT) appear to provide the best results. Evidence to guide the choice between the two is sparse. Therefore, this review provides an overview of the available evidence on RSA versus NOT. Methods: Studies comparing complex proximal humerus fractures in patients aged >65 years treated either with RSA or NOT were included for systematic review and direct comparison via pooled analysis of patient-rated outcome and range of motion. Indirect comparison of case series and non-comparative studies on either treatment was performed separately. Results: Three comparative studies including 77 patients treated with RSA and 81 treated non-operatively were analysed. The RSA group scored better for both the Constant-Murley score (mean difference 6 points) and DASH score (mean difference 8 points). No differences were detected in ASES, PENN score, pain scores, or range of motion between treatment groups. The most common complications for RSA were infection (3%), nerve injury (2%), and dislocation (2%). Reoperation was required in 5%. In the NOT group, common complications included malunion (42%), osteonecrosis (25%), and non-union (3%); no reoperation was required. Patient satisfaction was equal in both groups. Conclusions: The functional outcomes and range of motion after RSA seemed satisfactory and potentially superior to NOT in elderly patients. Patient satisfaction was comparable despite a high malunion and osteonecrosis rate in the non-operative treatment group, which did not require re-interventions.

Achieving satisfactory functional outcomes in conservatively treated proximal humerus fractures: relationship between shoulder range of motion and patient-reported clinical outcome scores

Background

Proximal humerus fractures are common osteoporotic fractures. Postinjury outcome measures include objective clinician-measured range of motion (ROM) and subjective patient-reported outcome measures (PROMs), but the relationship between both has not been established. This study aimed to determine the relationship between shoulder ROM and PROMs and establish which ROMs correlated most with PROMs.

Methods

A prospective cohort study was conducted on patients with acute proximal humerus fractures. Surgical intervention, open or pathological fractures, neurovascular compromise, polytrauma, or delayed presentations were excluded. Correlation and regression analyses between active ROM and PROMs (Quick Disabilities of Arm, Shoulder and Hand [QuickDASH] and Oxford Shoulder Score [OSS]) at 1-year postinjury were explored. ROM cutoffs predicting satisfactory PROM scores were established.

Results

Fifty-five patients were recruited. Moderate correlations were observed between PROMs and flexion, extension, and abduction, but not internal and external rotation. Multivariate analysis showed significant relationships between PROMs and flexion [QuickDASH: adjusted coefficient (AC): -0.135, P = .013, OSS: AC: 0.072, P = .002], abduction [QuickDASH: AC: -0.115, P = .021, OSS: AC: 0.059, P = .005], and extension [QuickDASH: AC: -0.304, P = .020] adjusting for age, gender, Neer classification, injury on dominant side, and employment. Achieving 130° flexion, 59° extension, and 124° abduction were correlated with satisfactory OSS/QuickDASH scores, respectively.

Conclusion

Overall, holistic assessment of outcomes with both subjective and objective outcomes are necessary, as shoulder flexion, extension, and abduction are only moderately correlated with PROMs. Attaining 130° flexion, 59° extension, and 124° abduction corresponded with satisfactory functional outcomes measured by OSS/QuickDASH and can guide rehabilitation.

Valgising angular stable plate fixation in the treatment of multifragmentary proximal humeral fractures in elderly patients

INTRODUCTION

The frequency of proximal humeral fractures shows an increasing tendency, especially in the elderly, who are frequently affected by osteoporosis. The adequate treatment of complex, displaced fractures poses a serious challenge. Among surgical treatment options, osteosynthesis with an angular stable plate is preferred, however, the implant-related complication rate may be exceptionally high. In our present study, we report the short-term outcomes of our new method of valgising angular stable plate fixation which we use for multifragmentary, displaced proximal humeral fractures in elderly patients.

MATERIALS AND METHODS

We retrospectively evaluated the clinical and radiological outcomes of 52 patients (46 female and 6 male, age: 71.9 ± 9.6) who suffered dislocated three- or four-part fractures and underwent valgising angular stable plate fixation.

RESULTS

Mean follow-up time was 17.3 months, while the functional outcomes were as following: excellent in 26, good in 18, moderate in 5 and poor in 3 patients. The mean Constant-Murley Score was 82.5 ± 11.2. Functional outcomes only showed significant correlation (p = 0.031) with age and were proven unrelated to fracture type, BMI and known primary diseases. The cumulative complication rate was 9.6% and revision rate was 5.8%. Neurological deficit, pseudoarthrosis or avascular humeral head necrosis did not occur during the follow-up period.

CONCLUSIONS

Valgising angular stable plate fixation that we apply for proximal humeral fractures provided favourable functional outcomes and a low postoperative complication rate due to the optimal head and plate placement. The method is especially effective for the treatment of displaced three- and four-part fractures with weakened, osteoporotic bone structure.

Proximal humerus fractures: Postoperative protocols and factors affecting treatment decisions among shoulder and elbow and orthopedic trauma surgeons

Background

Proximal humerus fractures (PHFs) can lead to functional decline in geriatric and polytraumatized patients. Treatment of PHFs is an area of much debate and much variability between practitioners.

Objectives

We surveyed orthopedic trauma (OT) and shoulder and elbow (SE) surgeons to evaluate differences in postoperative protocols when treating acute PHFs with open reduction internal fixation (ORIF), intramedullary nailing (IMN), or hemi or reverse shoulder arthroplasty (rTSA).

Materials and methods

We distributed a web-based survey to three OT and SE associations between August 2018-April 2019. Questions included practice characteristics, standard postoperative protocols for weight-bearing, lifting, and range of motion (ROM) by treatment modality, and factors affecting modality and postoperative protocol decisions. We compared the subspecialties.

Results

239 surgeons [100 (42.2 %) OT, 118 (49.8 %) SE] completed the survey. OT were more likely to allow immediate ROM, lifting, and weight bearing following intramedullary nailing (IMN), open reduction internal fixation with a locking plate (ORIF), or arthroplasty (all p < 0.025), and to allow earlier unrestricted use of the extremity following IMN and arthroplasty (p = 0.001, p = 0.021 respectively). OT were more likely to consider operating on a PHF if there was contralateral upper extremity injury or need of the injured arm for work or activities of daily living (all p < 0.026). The subspecialties did not differ significantly on factors affecting their postoperative protocols. OT preferred IMN and SE surgeons preferred rTSA for allowing immediate unrestricted postoperative weight bearing, ROM, or lifting (all p < 0.001).

Conclusion

There are significant differences in postoperative protocols between trauma and SE surgeons when treating PHFs. Postoperative protocols should be further studied to balance surgical outcomes and the risks of functional decline when treating patients with PHFs.

Transitivity, coherence, and reliability of network meta-analyses comparing proximal humerus fracture treatments: a meta-epidemiological study

BACKGROUND

Network meta-analyses can be valuable for decision-makers in guiding clinical practice. However, for network meta-analysis results to be reliable, the assumptions of both transitivity and coherence must be met, and the methodology should adhere to current best practices. We aimed to assess whether network meta-analyses of randomized controlled trials (RCTs) comparing interventions for proximal humerus fractures provide reliable estimates of intervention effects.

METHODS

We searched PubMed, EMBASE, The Cochrane Library, and Web of Science for network meta-analyses comparing interventions for proximal humerus fractures. We critically assessed the methodology regarding the development of a protocol, search strategy, trial inclusion, outcome extraction, and the methods used to conduct the network meta-analyses. We assessed the transitivity and coherence of the network graphs for the Constant score (CS), Disabilities of the Arm, Shoulder, and Hand score (DASH), and additional surgery. Transitivity was assessed by comparing probable effect modifiers (age, gender, fracture morphology, and comorbidities) across intervention comparisons. Coherence was assessed using Separating Indirect from Direct Evidence (SIDE) (Separating Indirect from Direct Evidence) and the design-by-treatment interaction test. We used CINeMA (Confidence in Network Meta-analyses) to assess the confidence in the results.

RESULTS

None of the three included network meta-analyses had a publicly available protocol or data-analysis plan, and they all had methodological flaws that could threaten the validity of their results. Although we did not detect incoherence for most comparisons, the transitivity assumption was violated for CS, DASH, and additional surgery in all three network meta-analyses. Additionally, the confidence in the results was 'very low' primarily due to within-study bias, reporting bias, intransitivity, imprecision, and heterogeneity.

CONCLUSIONS

Current network meta-analyses of RCTs comparing interventions for proximal humerus fractures do not provide reliable estimates of intervention effects. We advise caution in using these network meta-analyses to guide clinical practice. To improve the utility of network meta-analyses to guide clinical practice, journal editors should require that network meta-analyses are done according to a predefined analysis plan in a publicly available protocol and that both coherence and transitivity have been adequately assessed and reported.

Blood transfusion and surgical treatment increase mortality in patient with proximal humeral fractures

INTRODUCTION

Proximal humeral fractures (PHFs) often occur in elderly patients with osteoporosis and associated comorbidities. These patients constitute a special risk group. This study aimed to identify associations between comorbidities, treatment type, and mortality risk.

PATIENTS AND METHODS

We conducted a retrospective chart review of a cohort of 350 patients with a diagnosis of PHF and a mean follow-up of 4.5 years. We analysed the 19 prefracture comorbidities included in the Charlson Comorbidity Index (CCI), haemoglobin (Hb) levels, blood transfusion needs, and treatment administered (surgery versus conservative). The nonparametric Kaplan-Meier method and Cox proportional hazards model were used to estimate the mortality risk.

RESULTS

Over a 4.5-year average follow-up of 350 patients, primarily elderly females, with proximal humerus fractures, several factors were associated with increased mortality. The Charlson Comorbidity Index (CCI) was a significant predictor, with patients having a CCI > 5 facing higher mortality risks, especially if they underwent surgery. Additionally, osteosynthesis was linked to a lower mortality rate compared to arthroplasty. Age, dementia, medical complications, and postfracture Hb level also influenced mortality rates. CONCLUSIóN: These findings emphasize the importance of considering comorbidities, specifically the Charlson Comorbidity Index (CCI), in determining patient outcomes, especially amongst elderly patients with proximal humerus fractures. Factors like age, dementia, and postfracture Hb level also play a crucial role in influencing mortality rates.

TRIAL REGISTRATION

The study received written approval from the regional Ethics Committee for Clinical Research (code 2016/125).

Trauma (Excluding Falls) in the Older Adult

Trauma in the older adult will increasingly become important to emergency physicians hoping to optimize their patient care. The geriatric patient population possesses higher rates of comorbidities that increase their risk for trauma and make their care more challenging. By considering the nuances that accompany the critical stabilization and injury-specific management of geriatric trauma patients, emergency physicians can decrease the prevalence of adverse outcomes.

A systematic review of biopsychosocial prognostic factors of recovery after a proximal humerus fracture

BACKGROUND

Proximal humerus fracture (PHF) is a common upper extremity injury. PHF often causes prolonged disability and interferes with independent function.

PURPOSE

This study reviewed and summarized prognostic factors of recovery following PHF and classified them within the International Classification of Functioning, Disability and Health (ICF) with each domain sub-categorized by modifiability.

STUDY DESIGN

Systematic review.

METHODS

We searched MEDLINE, CINAHL, EMBASE, and PsychINFO from the date of database inception to March 2019 and updated searches in December 2021. Studies included examining an association between prognostic factors and recovery with at least a 6-month follow-up. Two independent reviewers used the Quality in Prognosis Studies tool for methodological bias and levels of evidence. Designs showed wide variability in terms of characteristics of the included population, definition of recovery, assessment of prognostic factors, and outcome measures used. This prevented pooled estimates from being produced. Prognostic factors linked to ICF domains were possible.

RESULTS

Twenty-three studies including 4323 participants aged ≥18 met inclusion criteria. The risk of bias was low (35%), moderate (30%), and high (35%) across the included studies. Moderate evidence showed a significant association between pre-fracture functional independence and post-fracture complications with recovery. Fracture type, structural deformity, medication use, age, and gender were prognostic factors with inconclusive evidence. We assigned a weak level of evidence to the remaining 20 factors due to limited data. Immediate rehabilitation, compliance to post-fracture rehabilitation exercise, task-oriented exercise, and pain self-efficacy (i.e., coping behavior) are modifiable and are tapped into the ICF contextual factors.

CONCLUSIONS

An array of factors that fit within an ICF biopsychosocial framework have been investigated as potential mediators of outcomes after PHF. The evidence is incomplete conceptually and in terms of research design quality. Preoperative functional status is predictive of functional recovery emphasizing the importance of healthy aging.

Social determinants of outcomes in nonoperatively treated proximal humerus fractures

Background

Proximal humerus fractures (PHFs) are common fractures especially in the elderly, with most fractures being managed nonoperatively. Traditional biomedical factors such as radiological alignment have not been able to meaningfully predict comfort and capability after PHFs. Conversely, recent literature has increasingly recognized the role of psychological factors in determining comfort and capability after PHFs. Nonetheless, less is known about the impact of social factors. Additional study of these potentially modifiable social factors as targets for enhancing recovery from injury is merited. Among people recovering from a nonoperatively- treated proximal humerus fracture (PHF) we studied the social factors associated with patient-reported outcomes at 6 months and 1 year.

Methods

One hundred seventy-one patients who received nonoperative management of a PHF completed baseline measures of sociodemographic characteristics (age, gender, race, employment status, household income, educational level, presence of domestic workers, housing type, and smoking status). Six and 12 months after fracture, participants completed the Oxford Shoulder Score (OSS), Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) and EuroQol-5-Dimensions (EQ5D) measures of comfort and capability. The relationship between capability and social factors was assessed using linear regression modelling, accounting for potential confounding from age, fracture severity assessed using Neer classification, premorbid comorbidities measured by Charlson Comorbidity Index, and premorbid functional status measured by Parker Mobility Index and Barthel Index.

Results

Lower capability (higher QuickDASH scores) 6 months and 1 year after fracture were associated with being unemployed (coef: -5.02 [95% CI: -9.96 to -0.07]; P = .047) and having domestic workers at home (coef: 8.63 [95% CI: 1.39 to 15.86]; P = .020), but not with Neer classification. Both greater shoulder discomfort and magnitude of incapability (lower OSS scores) and worse general quality of life (lower EQ5D scores) were associated with having domestic workers (coef: -4.07 [95% CI: -6.62 to -1.53]; P = .002 and coef: -0.18 [95% CI: -0.29 to -0.07]; P = .001 respectively) or living in an assisted care facility (coef: -14.82 [95% CI: -22.24 to -7.39]; P < .001 and coef: -0.59 [95% CI: -0.90 to -0.29] P < .001).

Conclusions

The finding that people recovering from PHF experience less incapability in proportion to their social independence (employment, absence of a caregiver such as domestic workers at home and living outside care facilities) emphasizes the important associations of social factors to musculoskeletal health, and the utility of accounting for social factors in the development and assessment of care strategies.

Proximal humerus fractures: A review of current practice

The management of proximal humeral fractures (PHF) remains controversial. Its incidence is increasing. Patients should be meticulously assessed clinically for co-morbidities and neuro-vascular injuries. Radiological investigation helps provide information on the fracture configuration and dislocations. Enhanced by 3-dimensional CT scanning, these further help in decision making and operative planning. PHF classifications have been demonstrated to have poor intra-observer and inter-observer reliability. Research has identified some radiographic predictive factors for humeral head ischaemia and likely failure of surgical fixation. The range of management options include non-operative treatment, operative fixation, intramedullary nailing and arthroplasty (hemiarthroplasty, reverse shoulder replacement). The majority of PHFs are stable injuries and non-operative management is usually successful. Some degree of malunion is readily tolerated especially by elderly patients. Surgical management of significantly displaced, unstable proximal humerus fractures should aim to stabilise the fracture adequately and provide satisfactory function for the long term. Management of the greater tuberosity is pivotal for the eventual outcome. When fixation may appear to be compromised by poor bone quality, likely poor function, age related rotator cuff degeneration or likely humeral head ischaemia clinicians may opt for arthroplasty. Successful hemiarthroplasty outcomes are dependent on sufficient healing of the tuberosity and recovery of the rotator cuff integrity. Reverse shoulder replacement can predictably deliver good functional outcomes for the shoulder in elderly patients, where rotator cuff dysfunction is suspected or as a revision procedure following failure of other surgical interventions. As opposed to hemiarthroplasty, which has shown a downward trend, there has been an increasing trend towards the use of reverse shoulder replacement in proximal humeral fractures. The management of PHFs should be patient specific, fracture specific and meet the functional demands and needs of the individual patient. The surgeon's skill set and clinical experience also plays an important role in the options of management available.

Prognostic factors and prediction model for 1-year mortality after proximal humeral fracture

The goal was to investigate if patient characteristics can be used to predict 1-year post-fracture mortality after proximal humeral fracture (PHF). A clinical prediction model showed that the combination of 6 pre-fracture characteristics demonstrated good predictive properties for mortality within 1 year of PHF.

INTRODUCTION

Proximal humeral fractures (PFH) are the third most common major non-vertebral osteoporotic fractures in older persons and result in an increased mortality risk. The aim of this study was to investigate if patient characteristics can be used to predict 1-year post-fracture mortality.

METHODS

Retrospective study with 261 patients aged 65 and older who were treated for a PHF in University Hospitals Leuven between 2016 and 2018. Baseline variables including demographics, residential status, and comorbidities were collected. The primary outcome was 1-year mortality. A clinical prediction model was developed using LASSO regression and validated using split sample and bootstrapping methods. The discrimination and calibration were evaluated.

RESULTS

Twenty-seven (10.3%) participants died within 1-year post-PHF. Pre-fracture independent ambulation (p < 0.001), living at home at time of fracture (p < 0.001), younger age (p = 0.006), higher BMI (p = 0.012), female gender (p = 0.014), and low number of comorbidities (p < 0.001) were predictors for 1-year survival. LASSO regression identified 6 stable predictors for a prediction model: age, gender, Charlson comorbidity score, BMI, cognitive impairment, and pre-fracture nursing home residency. The discrimination was 0.891 (95% CI, 0.833 to 0.949) in the training sample, 0.878 (0.792 to 0.963) in the validation sample and 0.756 (0.636 to 0.876) in the bootstrapping samples. A similar performance was observed for patients with and without surgery. The developed model demonstrated good calibration.

CONCLUSIONS

The combination of 6 pre-fracture characteristics demonstrated good predictive properties for mortality within 1 year of PHF. These findings can guide PHF treatment decisions.

Early Outcomes of Proximal Humerus Fractures in Adults Treated With Locked Plate Fixation Compared with Nonoperative Treatment: An Age-, Comorbidity-, and Fracture Morphology-Matched Analysis

OBJECTIVES

To compare patient-reported outcomes (PROs), range of motion (ROM), and complication rates for proximal humerus fractures managed nonoperatively or with open reduction internal fixation (ORIF).

DESIGN

Retrospective cohort.

SETTING

Academic level 1 trauma center.

PATIENTS/PARTICIPANTS

Four hundred thirty-one patients older than 55 years were identified retrospectively. 122 patients were excluded. 309 patients with proximal humerus fractures met inclusion criteria (234 nonoperative and 75 ORIF). After matching, 192 patients (121 nonoperative and 71 ORIF) were included in the analysis.

INTERVENTION

Nonoperative versus ORIF (locked plate) treatment of proximal humerus fracture.

MAIN OUTCOME MEASUREMENTS

Early Visual Analog Score (VAS), ROM, PROs, complications, and reoperation rates between groups.

RESULTS

At 2 weeks, ORIF showed lower VAS scores, better passive ROM, and patient-reported outcomes measurement information system (PROMIS) scores ( P < 0.05) compared with nonoperative treatment. At 6 weeks, open reduction internal fixation (ORIF) had lower VAS scores, better passive ROM, and PROMIS scores ( P < 0.05) compared with nonoperative treatment. At 3 months, ORIF showed similar PROMIS scores ( P > 0.05) but lower VAS scores and better passive ROM ( P < 0.05) compared with nonoperative treatment. At 6 months, ORIF showed similar VAS scores, ROM, and PROMIS scores ( P > 0.05) compared with nonoperative treatment. There was no difference in secondary operation rates between groups ( P > 0.05). ORIF patients trended toward a higher secondary reoperation rate (15.5% vs. 5.0%) than nonoperative patients ( P = 0.053).

CONCLUSIONS

In an age-, comorbidity-, and fracture morphology-matched analysis of proximal humerus fractures, ORIF led to decreased pain and improved passive ROM early in recovery curve compared with nonoperative treatment that normalized after 6 months between groups.

Proximal humerus fractures - epidemiology, comparison of mortality rates after surgical versus non-surgical treatment, and analysis of risk factors based on Medicare registry data

AIMS

The optimal choice of management for proximal humerus fractures (PHFs) has been increasingly discussed in the literature, and this work aimed to answer the following questions: 1) what are the incidence rates of PHF in the geriatric population in the USA; 2) what is the mortality rate after PHF in the elderly population, specifically for distinct treatment procedures; and 3) what factors influence the mortality rate?

METHODS

PHFs occurring between 1 January 2009 and 31 December 2019 were identified from the Medicare physician service records. Incidence rates were determined, mortality rates were calculated, and semiparametric Cox regression was applied, incorporating 23 demographic, clinical, and socioeconomic covariates, to compare the mortality risk between treatments.

RESULTS

From 2009 to 2019, the incidence decreased by 11.85% from 300.4 cases/100,000 enrollees to 266.3 cases/100,000 enrollees, although this was not statistically significant (z = -1.47, p = 0.142). In comparison to matched Medicare patients without a PHF, but of the same five-year age group and sex, a mean survival difference of -17.3% was observed. The one-year mortality rate was higher after nonoperative treatment with 16.4% compared to surgical treatment with 9.3% (hazard ratio (HR) = 1.29, 95% confidence interval (CI) 1.23 to 1.36; p < 0.001) and to shoulder arthroplasty with 7.4% (HR = 1.45, 95% CI 1.33 to 1.58; p < 0.001). Statistically significant mortality risk factors after operative treatment included age older than 75 years, male sex, chronic obstructive pulmonary disease (COPD), cerebrovascular disease, chronic kidney disease, a concomitant fracture, congestive heart failure, and osteoporotic fracture.

CONCLUSION

Mortality risk factors for distinct treatment modes after PHF in elderly patients could be identified, which may guide clinical decision-making.Cite this article: Bone Joint Res 2023;12(2):103-112.

Mortality following proximal humerus fracture-a nationwide register study of 147,692 fracture patients in Sweden

Little is known about survival after proximal humerus fracture. In this manuscript, we found the mortality to be high (almost four times higher than in age- and sex-matched controls). While frailty hip fracture has gained attention, we hope our manuscript will shed light on frailty proximal humerus fracture patients.

INTRODUCTION

Proximal humerus fractures (PHF) are common and occur mostly after the 6th decade of life. While mortality following PHF has been reported previously, mortality data after longer follow-up on a national level is lacking.

METHODS

We obtained data from the Swedish Hospital Discharge Register (SHDR), on all adult patients (≥ 18 years) with a diagnosis of PHF (S42.2, S42.20, or S42.21) for the period between 2001 and 2016. We used the Swedish Cause of Death Register (SCDR) to investigate mortality in the fracture cohort. We compared the mortality of fracture patients with age- and sex-matched population-based mortality data obtained from Statistics Sweden.

RESULTS

A total of 147 692 PHF patients were identified, with a male to female ratio of 1:3. The mean age was 69 years (range, 18 to 111). Most patients were treated non-surgically (n = 126,487, 86%). The crude mortality rate was 2.2% at 1 month, 4.1% at 3 months, 8.5% at 12 months, and 24% at 48 months after sustaining a PHF. Mortality increased with age; however, the standardized mortality rate (SMR) was highest among young patients. SMR was 5.4 in the 18- to 39-year age group, 3.9 in the 40- to 64-year age group, 1.8 in the 65-79-year age group, and 1.2 in the ≥ 80-year-old population. The age-adjusted SMR was 3.9 in the whole adult PHF population.

CONCLUSION

The mortality rate and SMR suggest that PHF patients are heterogeneous. Some older PHF patients may benefit from specialized care (e.g., orthogeriatric), and this should be evaluated in future studies.

Combined Humeral Head and Shaft Fractures: Outcome Following Intramedullary Nailing and Plating

Background and Objectives: Combined fractures of the humeral head and shaft (FHS) are rare but frequently involve an intermuscular fracture as its characteristic pattern. The aim of this retrospective study was to investigate intramedullary nailed and plated FHS in terms of outcomes and complications. Materials and Methods: The present study included patients with FHS, treated via either intramedullary nailing or plating within a period of 10 years, with a minimum follow-up of 12 months. Functional outcome was assessed using the age- and sex-adapted Constant-Murley Score (CMS-K). Rates of complications and revision surgeries were registered. Results: Twenty-five patients (18 females, 7 males, age 60.1 ± 14.2 years, range 23-76 years) were included in the study. Nailing was performed in 16 patients (12 females, 4 males, age 62.6 ± 12.4 years), whereas plating was executed in nine patients (6 females, 3 males, age 55.8 ± 17.0 years). Follow-up among all patients was 45.1 ± 26.3 months (range 12-97 months). CMS-K was 70.3 ± 32.3 in the nailing group, with reoperation in four cases, and 76.0 ± 31.0 in the plating group, with one reoperation (p = 0.42). Patients with no metaphyseal fragment displacement (n = 19; CMS-K 76.7 ± 17.3) demonstrated significantly better functional outcomes versus those with secondary displacement of the metaphyseal fragments (n = 6; CMS-K 60.0 ± 17.1), p = 0.046. Conclusions: Comparable acceptable clinical outcome is obtained when comparing nailing with additional open cerclage or lag-screw fixation techniques versus plating with open reduction. However, a higher revision rate was observed after nailing. The correct metaphyseal fragment fixation seems to be crucial to avoid loss of reduction and hence the need for revision surgery, as well as a worse outcome.

Anatomically reduced fixation should always be considered when treating B and C proximal epiphyseal humeral fractures

Background

Proximal humeral fractures are commonly observed in elderly patients. Management of these injuries is controversial. Literature comparing locking plate fixation, arthroplasty, and conservative treatments show no clear advantages for any of these management strategies. Thus far, no study has considered anatomically reduced fractures obtained after locking plate treatment. To clarify the best surgical procedure in middle-aged patients, we considered outcomes and major complications leading to surgical revision following an anatomically reduced fracture fixed with locking plate and reverse shoulder arthroplasty (RSA) in the treatment of type B/C fractures in patients between 50 and 75 years of age.

Methods

This is a retrospective study including 59 patients between 50 and 75 years of age with type B/C proximal humeral fracture treated with RSA or with locking plate fixation (resulting in an anatomical reduction) between January 2010 and December 2018. Preoperative radiographs and computed tomography (CT) were evaluated in all patients. Clinical and radiologic follow-up was performed using range of motion (ROM), the Constant–Murley Score (CMS), the Oxford Shoulder Score (OSS), the Simple Shoulder Test (SST), the Subjective Shoulder Value (SSV), and visual analog scale (VAS). Major complications were considered.

Results

In the plate fixation group, ROM, CMS, SST, and VAS were higher than in the RSA group. Lower complication rates compared with the literature were observed in both groups. Anatomically reduced fracture fixed with plate and screw could outperform RSA in terms of outcome. In second-level centers where traumatology is performed by surgeons with great expertise in upper limb trauma, the choice between plate fixation and reverse arthroplasty should be made during surgery.

Conclusion

Anatomically reduced fractures showed better outcomes compared with RSA in type B/C fractures. Surgeons should always try to perform a reduction of the fracture in order to understand if a plate fixation could be feasible. If it is impossible to perform an anatomical reduction, we suggest to consider RSA. This is a retrospective observational study.

MORTALITY AFTER SURGICAL TREATMENT OF PROXIMAL HUMERUS FRACTURES IN OLDER PATIENTS

Mortality of patients after osteosynthesis of proximal humeral fractures (PHF) has been poorly studied in contrast to fractures of the proximal femur.

OBJECTIVE

To evaluate the mortality of older patients with PHF undergoing surgical treatment.

METHODS

Retrospective study of patients undergoing surgical treatment PHF between 2009-2019. Demographic data, Neer classification, and mortality of this cohort of patients were evaluated. Non-categorical variables were tested using the Kolmogorov-Smirnov test. The unpaired t-test (parametric variables) was used. Categorical variables were tested by Fisher's exact test. A Kaplan-Meier mortality curve was constructed.

RESULTS

59 patients were evaluated. There was a predominance of females in the sixth decade of life. The most prevalent fractures were Neer's type III. The highest mortality occurred in the first 4 years after surgery (4.1 + 3.2 years). The only comorbidity capable of changing the survival curve was DM (p = 0.03) Conclusion: Overall mortality was 11.3%. The highest mortality occurred in the first 4 years of follow-up. Diabetic patients evolve with earlier mortality and have 7 times more chance of death. Level of Evidence III, Retrospective Study.

Outcomes for type C proximal humerus fractures in the adult population: comparison of nonoperative treatment, locked plate fixation, and reverse shoulder arthroplasty

Background

This study compares patient-reported outcomes and range of motion (ROM) between adults with an AO Foundation/Orthopaedic Trauma Association type C proximal humerus fracture managed nonoperatively, with open reduction and internal fixation (ORIF), and with reverse shoulder arthroplasty (RSA).

Methods

This is a retrospective cohort study of patients >60 years of age treated with nonoperative management, ORIF, or RSA for AO Foundation/Orthopaedic Trauma Association type 11C proximal humerus fractures from 2015 to 2018. Visual analog scale pain scores, Patient-Reported Outcomes Measurement Information System (PROMIS) scores, ROM values, and complication and reoperation rates were compared using analysis of variance for continuous variables and chi square analysis for categorical variables.

Results

A total of 88 patients were included: 41 nonoperative, 23 ORIF, and 24 RSA. At the 2-week follow-up, ORIF and RSA had lower visual analog scale scores and lower PROMIS pain interference scores (P < .05) than nonoperative treatment. At the 6-week follow-up, ORIF and RSA had lower visual analog scale, PROMIS pain interference, and PF scores and better ROM (P < .05) than nonoperative treatment. At the 3-month follow-up, ORIF and RSA had better ROM and PROMIS pain interference and PF scores (P < .05) than nonoperative treatment. At the 6-month follow-up, ORIF and RSA had better ROM and PROMIS PF scores (P < .05) than nonoperative treatment. There was a significantly higher complication rate in the ORIF group than in the non-operative and RSA groups (P < .05).

Conclusion

The management of AO Foundation/Orthopaedic Trauma Association type 11C proximal humerus fractures in older adults with RSA or ORIF led to early decreased pain and improved physical function and ROM compared to nonoperative management at the expense of a higher complication rate in the ORIF group.

What Factors Are Associated With Poor Shoulder Function and Serious Complications After Internal Fixation of Three-part and Four-part Proximal Humerus Fracture-dislocations?

BACKGROUND

Three-part and four-part fracture-dislocations of the proximal humerus are characterized by severe soft tissue disruptions that can compromise the viability of the humeral head. As a result, nonunion and avascular necrosis are more common in these injuries. In such injuries, surgical treatment (internal fixation or arthroplasty) is performed in most patients who are determined to be fit for surgery to potentially restore shoulder function. Although the decision to preserve or replace the humeral head is simple in young patients or those > 65 years, in most other patients, the decision can be complicated, and little is known about which patient-related and injury-related factors may be independently associated with poor shoulder function or complications like avascular necrosis.

QUESTIONS/PURPOSES

(1) What proportion of fractures united after internal fixation of a three-part or four-part fracture-dislocation of the proximal humerus, what is the mean Constant score at a minimum of 2 years after this injury, and what proportion had serious complications (such as loss of fixation, nonunion, reoperation, or avascular necrosis)? (2) After controlling for potential confounding variables, what factors are independently associated with poor shoulder function (defined as a Constant score < 55 out of 100) and occurrence of serious complications such as loss of fixation or reduction resulting in revision surgery, nonunion, or radiographic evidence of avascular necrosis of the humeral head?

METHODS

Between 2011 and 2017, the senior author of this study (ASG) treated 69 patients with three-part or four-part proximal humerus fracture dislocations. During this time, indications for internal fixation in these patients were adequate humeral bone quality as determined by the surgeon on radiographs, adequate bone stock and volume available for fixation in the humeral head as determined on CT images, and the absence of a head split component as assessed on preoperative radiographs and CT images. On this basis, 87% (60 patients) underwent internal fixation with a locked plate and suture fixation of the tuberosities through a deltopectoral approach. Thirteen percent (nine patients) underwent either a hemiarthroplasty or a reverse total shoulder arthroplasty. Of the 60 patients who underwent internal fixation, four declined to participate in the study and two with brachial plexus palsy were not considered for inclusion. This study focused on the remaining 54 patients who were considered potentially eligible. To be included, a minimum follow-up of 2 years was required; 11% (6 of 54) were lost before that time, and the remaining 48 patients were analyzed at a mean of 48 months ± 17 months in this retrospective study, which drew data from longitudinally maintained institutional databases. Fracture union was assessed by obliteration of fracture lines and the presence of bridging trabecular bone on plain radiographs. Shoulder function was assessed using the Constant score, which is scored from 0 to 100 points, with 0 indicating the most disability and 100 the least disability. The anchor-based minimal clinically important difference for the Constant score is 9.8 points. Twelve patient-related and injury-related factors were analyzed using a multivariate regression model to identify factors that are independently associated with poor results after internal fixation as measured by shoulder function and the occurrence of serious complications. We categorized results as poor if patients had one or more of the following: Constant score < 55 out of 100 at the last follow-up examination (for patients who underwent revision surgery, the Constant score immediately before revision was considered) and loss of fixation or reduction resulting in revision surgery, nonunion, or avascular necrosis of the humeral head. Patients were screened for avascular necrosis at 6 and 12 months after surgery, then annually for another 2 years. Further assessments were made only based on symptoms.

RESULTS

Seventy-nine percent of the fractures united within 18 weeks of surgery (38 of 48), and an additional 13% united by 24 weeks (6 of 48), while 8% did not unite (4 of 48). The mean Constant score at the last follow-up was 68 ± 12. Twenty-one percent (10 of 48) had a Constant score < 55, indicating poor shoulder function. Twenty-one percent (10 of 48) experienced avascular necrosis, and 15% (7 of 48) with either nonunion or avascular necrosis underwent revision shoulder arthroplasty. Two patients who underwent arthroplasty had both nonunion and avascular necrosis. After controlling for potentially confounding variables, we found that being a woman (odds ratio 1.7 [95% confidence interval 1.4 to 2.1]; p = 0.01), four-part fracture dislocations (OR 2.1 [95% CI 1.5 to 2.7]; p < 0.001), absence of a metaphyseal head extension (OR 2.4 [95% CI 1.8 to 3.3]; p < 0.001), absence of active back-bleeding from the humeral head (OR 3.4 [95% CI 2.3 to 5.1]; p < 0.001), height of the head segment < 2 cm (OR 2.3 [95% CI 1.8 to 2.8]; p < 0.001), and absence of capsular attachments to the head fragment (OR 2.2 [95% CI 1.6 to 2.9]; p < 0.001) were independently associated with poor shoulder function and the occurrence of complications such as nonunion and avascular necrosis.

CONCLUSION

Internal fixation of three-part and four-part proximal humerus fracture dislocations resulted in poor shoulder function and complications in a high number of patients, although fracture union was achieved in most patients. A nonunion proportion of 8%, 21% proportion of avascular necrosis, and 15% proportion of patients who underwent revision surgery suggests this is a fairly terrible injury. Being a woman and injury factors such as four-part fracture dislocation, absent metaphyseal head extension and back-bleeding from the head, height of the fractured head segment < 2 cm, and absence of capsular attachments to the head were independently associated with poor function and complications. Our findings can help surgeons decide between internal fixation and arthroplasty for the surgical treatment of these injuries in patients across different age groups and functional demands.

Assessing the ability of an instrumental variable causal forest algorithm to personalize treatment evidence using observational data: the case of early surgery for shoulder fracture

Background

Comparative effectiveness research (CER) using observational databases has been suggested to obtain personalized evidence of treatment effectiveness. Inferential difficulties remain using traditional CER approaches especially related to designating patients to reference classes a priori. A novel Instrumental Variable Causal Forest Algorithm (IV-CFA) has the potential to provide personalized evidence using observational data without designating reference classes a priori, but the consistency of the evidence when varying key algorithm parameters remains unclear. We investigated the consistency of IV-CFA estimates through application to a database of Medicare beneficiaries with proximal humerus fractures (PHFs) that previously revealed heterogeneity in the effects of early surgery using instrumental variable estimators.

Methods

IV-CFA was used to estimate patient-specific early surgery effects on both beneficial and detrimental outcomes using different combinations of algorithm parameters and estimate variation was assessed for a population of 72,751 fee-for-service Medicare beneficiaries with PHFs in 2011. Classification and regression trees (CART) were applied to these estimates to create ex-post reference classes and the consistency of these classes were assessed. Two-stage least squares (2SLS) estimators were applied to representative ex-post reference classes to scrutinize the estimates relative to known 2SLS properties.

Results

IV-CFA uncovered substantial early surgery effect heterogeneity across PHF patients, but estimates for individual patients varied with algorithm parameters. CART applied to these estimates revealed ex-post reference classes consistent across algorithm parameters. 2SLS estimates showed that ex-post reference classes containing older, frailer patients with more comorbidities, and lower utilizers of healthcare were less likely to benefit and more likely to have detriments from higher rates of early surgery.

Conclusions

IV-CFA provides an illuminating method to uncover ex-post reference classes of patients based on treatment effects using observational data with a strong instrumental variable. Interpretation of treatment effect estimates within each ex-post reference class using traditional CER methods remains conditional on the extent of measured information in the data.

Health Care for Inpatients with a Proximal Humeral Fracture - an Analysis of Health Insurance Data

BACKGROUND

The proximal humeral fracture is one of the most common fractures in the elderly. While epidemiological factors have been well studied, the influence of a proximal humeral fracture on morbidity, mortality and associated costs has not yet been adequately analysed.

METHOD

On a basis of 4.1 million insurance holders of the German public health insurance (GKV), patients with (study population, SP) and without (comparison group, VG) a proximal humeral fracture (pHF) were compared with regard to comorbidity, rehospitalisation, mortality, drug and aid needs as well as number of physician contacts. Study period was between 2012 and 2016.

RESULTS

6068 patients of the SP met the inclusion and exclusion criteria (age 69.4 ± 14.3 years; male : female = 28.2% : 71.8%). 4781 patients (78.8%) received surgical, 1287 patients (21.2%) conservative treatment of the pHF. Rehospitalisations and visits to the general practitioner occurred more frequently in the SP vs. VG (p < 0.01). Contacts with specialists after pHF varied according to specialty, as did newly occurring diseases. Typical specialities for preventive examinations were significantly less common (gynaecology p < 0.01, pathology p < 0.01, dermatology p < 0.01). According to pHF, the costs of SP for drugs (2490.76 ± 1395.51 € vs. 2167.86 ± 1314.43 €; p = 0.04), medical therapies (867.01 ± 238.67 € vs. 393.26 ± 217.55 €; p < 0.01) and aids (821.02 ± 415.73 € vs. 513.52 ± 368.76 €; p < 0.01) were significantly above the VG. The two-year survival after pHF is lower in the SP than in the VG (p < 0.01).

DISCUSSION

The results show increased morbidity and mortality as well as medical costs after a proximal humeral fracture. Preventive examinations and treatments are rarer. In the future, care concepts for patients with proximal humeral fractures should not only be optimised with regard to functional scores and reduced complication rates, but also with regard to quality of life and preservation of general health.

Functional Outcome After Nonoperative Treatment of a Proximal Humeral Fracture in Adults

BACKGROUND

The functional outcome following nonoperative treatment of a proximal humeral fracture and the factors that influence it are poorly defined. We aimed to prospectively assess patient-reported outcome measures (PROMs) in a patient cohort at 1 year after the injury.

METHODS

In this study, 774 adult patients sustaining a proximal humeral fracture completed PROM assessments, including the Oxford Shoulder Score (OSS), the EuroQol-5 Dimensions-3 Levels (EQ-5D-3L), and visual analog scale (VAS) assessments of pain, health, and overall treatment satisfaction at 1 year. The mean patient age was 65.6 years, and 73.8% of patients were female. The influences of demographic and fracture measurements and complications on the OSS and EQ-5D-3L were assessed.

RESULTS

The 1-year mean scores were 33.2 points (95% confidence interval [CI], 32.1 to 34.2 points) for the OSS and 0.58 (95% CI, 0.55 to 0.61) for the EQ-5D-3L. There was considerable heterogeneity in the reported scores, and the 3 demographic variables of higher levels of dependency, higher levels of social deprivation, and a history of affective (mood) disorder were most consistently associated with poorer outcomes, accounting for between 37% and 43% of the score variation. The initial fracture translation potentially leading to nonunion accounted for 9% to 15% of the variation, and a displaced tuberosity fracture was also predictive of 1% to 4% of the outcome variation. There was evidence of a ceiling effect for the OSS, with 238 patients (30.8%) having a score of ≥47 points but a mean outcome satisfaction of only 72.9 points, and this effect was more pronounced in younger, active individuals. At the other end of the spectrum, 239 patients (30.9%) reported an OSS of ≤24 points, and 120 patients (15.5%) had a "worse-than-death" EQ-5D-3L score.

CONCLUSIONS

Nonoperative treatment of proximal humeral fractures produces considerable variation in shoulder-specific and general health outcomes at 1 year, and a substantial proportion of patients have poor perceived functional outcomes. The outcome for the majority of less-displaced fractures is mainly influenced by preexisting patient-related psychosocial factors, although the fracture-related factors of displacement, nonunion, and tuberosity displacement account for a small but measurable proportion of the variation and the poorer outcomes in the minority with more severe injuries.

Proximal Humerus Fractures: Epidemiology and trends in surgical management of hospital-admitted patients in Portugal

Background

Proximal humerus fractures (PHFs) are frequent and associated with significant health care burden. National epidemiological data are limited. Our objective is to characterize the Portuguese population admitted with PHFs and analyze therapeutic management, the impact of associated lesions, and mortality rate.

Methods

This was a retrospective, observational study of admissions from mainland public hospitals (2000-2015), with primary or secondary diagnosis of PHFs. Incomplete records, pathologic lesions, malunion/nonunion, and hardware removal were excluded. Age, gender, admission date, hospitalization period, associated injuries, treatment, and mortality were recorded.

Results

A total of 19,290 patients were included. Through the analyzed period, an increase in the absolute number and incidence of PHFs was observed. The mean age at diagnosis was 62.6 ± 21.0 years old (57% elderly; 63.5% female). The mean length of stay was 10.0 ± 14.1 days, higher in patients submitted to arthroplasty (P < .001) and in those with associated fractures (25%; P < .001). A total of 14,482 patients were operated, most frequently with open reduction and internal fixation (28%). The inpatient mortality rate was 3.2%, significantly higher in patients with associated fractures (odds 2.77 for lower limb vs. upper limb).

Conclusion

There is a trend toward an increase in surgical management of PHFs. The relative proportion of open reduction and internal fixation and arthroplasty (particularly reverse arthroplasty) increased, probably reflecting biomechanical implant properties, fracture pattern, and demand for better functionality. Associated fractures are an important comorbidity, associated with increased mortality and length of stay.

No change in reoperation rates despite shifting treatment trends: a population-based study of 4,070 proximal humeral fractures

Background and purpose - Clear and acknowledged treatment algorithms for proximal humeral fractures (PHFs) are lacking. Nevertheless, a change in treatment trends, including a change towards more reversed shoulder arthroplasties (RSA), has been observed during recent years. We examined the effect of these changes on reoperation rates.Patients and methods - Between 2011 and 2017, 4,070 PHFs treated at Sahlgrenska University Hospital were registered prospectively in the Swedish Fracture Register (SFR) and followed up until 2019 (mean follow-up of 4.5 years). Data on all reoperations were gathered from the SFR and from medical records.Results - The majority of PHFs were treated non-surgically and the proportion increased slightly, but not statistically significantly, during the study period (from 76% to 79%). Of the surgically treated fractures, the proportion fixed with a plate decreased from 47% to 25%, while the use of RSA increased 9-fold (from 2.0% to 19%). 221 patients underwent 302 reoperations. For those primarily treated surgically, the reoperation rate was 17%. Among treatment modalities, plate fixation was associated with the highest reoperation rate (21%). Rate of reoperations remained constant during the study period, both for the entire study cohort and for the surgically treated patientsInterpretation - During the study period, treatment changes that are in accordance with recently published treatment recommendations were observed. However, these treatment changes did not affect the reoperation rate. Treatment with a plate, intramedullary nail, or hemiarthroplasty was associated with the highest reoperation rates. The fact that almost every 4th surgical procedure was a reoperation indicates a need for further improvement of modern treatment concepts for PHFs.

Impact of non-hip fractures in elderly women: a narrative review

The association of hip fractures with adverse outcomes is well established, but for non-hip fractures this association still needs to be further investigated. The objective of this narrative review is to describe the state of the art with regards to the health impact of clinically relevant non-hip fracture locations in postmenopausal women. PubMed and Scopus databases were searched from January 2010 until December 2020. Studies were included when the crude rates and/or relative risk of 1-year subsequent fractures and/or mortality were reported as well as the precise fracture site. Twenty-three studies met the inclusion criteria. Regarding mortality rates, there was a high variability between studies, with higher rates for vertebral, proximal humerus and pelvic fractures. There was a small or no impact of wrist, ankle or tibia fractures. The mortality rate increased with age after vertebral, proximal humerus and wrist fractures. Moreover, proximal humerus and vertebral fractures were associated with a higher mortality risk. This narrative review indicates that, besides fractures of the hip, fractures of the vertebrae, proximal humerus or pelvis deserve more attention when trying to prevent adverse outcomes of osteoporosis. More studies on the topic of non-hip fractures are urgently needed.

Effect of chronic kidney disease on outcomes following proximal humerus fragility fracture surgery in diabetic patients: A nationwide population-based cohort study

BACKGROUND

The proximal humerus fracture (PHF) is the third most common fragility fracture. Diabetes mellitus (DM) and chronic kidney disease (CKD) are both risks for fragility fractures; however, the interplay of DM and CKD makes treatment outcomes unpredictable. This study aimed to investigate and compare early and late outcomes following proximal humerus fracture fixation surgery in diabetic patients with different renal function conditions.

METHODS

DM patients receiving PHF fixation surgery during 1998-2013 were recruited from Taiwan's National Health Insurance Research Database. According to their renal function, patients were divided into three study groups: non-chronic kidney disease (CKD), non-dialysis CKD, and dialysis. Outcomes of interest were early and late perioperative outcomes. Early outcomes included in-hospital newly-onset morbidities. Late outcomes included infection, revision, readmission, and all-cause mortality.

RESULTS

This study included a total of 10,850 diabetic patients: 2152 had CKD (non-dialysis CKD group), 196 underwent permanent dialysis (dialysis group), and the remaining 8502 did not have CKD (non-CKD group). During a mean follow-up of 5.56 years, the dialysis group showed the highest risk of overall infection, all-cause revision, readmission, and mortality compared to the non-dialysis CKD group and non-CKD group. Furthermore, subgroup analysis showed that CKD patients had a higher risk of surgical infection following PHF surgery than non-CKD patients in cases with a traffic accident or fewer comorbidities (Charlson Comorbidity Index, CCI <3) (P for interaction: 0.086 and 0.096, respectively). Also, CKD patients had an even higher mortality risk after PHF surgery than non-CKD patients, in females, those living in higher urbanization areas, or with more comorbidities (CCI ≥3) (P for interaction: 0.011, 0.057, and 0.069, respectively).

CONCLUSION

CKD was associated with elevated risks for infection, revision, readmission, and mortality after PHF fixation surgery in diabetic patients. These findings should be taken into consideration when caring for diabetic patients.

In-hospital Complications Are More Likely to Occur After Reverse Shoulder Arthroplasty Than After Locked Plating for Proximal Humeral Fractures

BACKGROUND

Currently, there seems to be a paradigm change in the surgical treatment of proximal humeral fractures in patients aged 65 years and older, with a considerable increase in the use of reverse total shoulder arthroplasty (RTSA) compared with angular stable internal fixation (locking plate fixation). However, even among shoulder specialists there is controversy regarding the best treatment strategy.

QUESTIONS/PURPOSES

To evaluate for (1) a greater risk of in-hospital major adverse events, (2) a greater risk for in-hospital surgical complications, and (3) a greater risk of 30-day mortality, locking plate fixation and RTSA were compared for the treatment of proximal humerus fractures of patients aged 65 years and older after controlling for potentially confounding variables in a large-database analysis.

METHODS

Health claims data of the largest German insurance company including approximately one-third of the population (26.5 million policyholders) between 2010 and 2018 were analyzed. This database was chosen because of its size, nationwide distribution, and high quality/completeness. In total, 55,070 patients (≥ 65 years of age) treated with locking plate fixation (75% [41,216]) or RTSA (25% [13,854]) for proximal humeral fracture were compared. As primary endpoints, major adverse events (including acute myocardial infarction, stroke, organ failure, resuscitation, and death) and surgical complications (infection, hematoma, loss of reduction, dislocation, and revision surgery) were analyzed. The risk of all endpoints was analyzed with multivariable logistic regression models in the context of comorbidities to address existing group differences.

RESULTS

After controlling for potentially confounding variables such as age, sex, and risk profile, RTSA was associated with a higher risk for major adverse events (OR 1.40 [95% CI 1.29 to 1.53]; p < 0.001) and surgical complications (OR 1.13 [95% CI 1.05 to 1.21]; p < 0.01) compared with locking plate fixation. There was no evidence for an increase in mortality (OR 0.98 [95% CI 0.86 to 1.12]; p = 0.81).

CONCLUSION

The increased in-hospital risk for major adverse events and surgical complications may moderate the enthusiasm associated with RTSA for proximal humeral fractures in patients 65 years and older. Treatment decisions should be based on individual risk estimation to avoid potential harmful events. Future studies must include long-term outcomes and quality of life to enlighten these findings in a broader context.

Can We Stratify Quality and Cost for Older Patients With Proximal and Midshaft Humerus Fractures?

Introduction:

This study sought to investigate whether a validated trauma triage tool can stratify hospital quality measures and inpatient cost for middle-aged and geriatric trauma patients with isolated proximal and midshaft humerus fractures.

Materials and Methods:

Patients aged 55 and older who sustained a proximal or midshaft humerus fracture and required inpatient treatment were included. Patient demographic, comorbidity, and injury severity information was used to calculate each patient’s Score for Trauma Triage in the Geriatric and Middle-Aged (STTGMA). Based on scores, patients were stratified to create minimal, low, moderate, and high risk groups. Outcomes included length of stay, complications, operative management, ICU/SDU-level care, discharge disposition, unplanned readmission, and index admission costs.

Results:

Seventy-four patients with 74 humerus fractures met final inclusion criteria. Fifty-eight (78.4%) patients presented with proximal humerus and 16 (21.6%) with midshaft humerus fractures. Mean length of stay was 5.5 ± 3.4 days with a significant difference among risk groups (P = 0.029). Lower risk patients were more likely to undergo surgical management (P = 0.015) while higher risk patients required more ICU/SDU-level care (P < 0.001). Twenty-six (70.3%) minimal risk patients were discharged home compared to zero high risk patients (P = 0.001). Higher risk patients experienced higher total inpatient costs across operative and nonoperative treatment groups.

Conclusion:

The STTGMA tool is able to reliably predict hospital quality measures and cost outcomes that may allow hospitals and providers to improve value-based care and clinical decision-making for patients presenting with proximal and midshaft humerus fractures.

Biological sex impacts perioperative complications after reverse shoulder arthroplasty for proximal humeral fracture

Background

The purpose of this study was to determine the difference in complication rates between males and females undergoing reverse shoulder arthroplasty for proximal humerus fractures. We hypothesized that (1) females were more likely to undergo reverse shoulder arthroplasty for fracture, and (2) males were more likely to sustain a perioperative complication.

Methods

The National Surgical Quality Improvement Program database was queried to identify patients who underwent reverse shoulder arthroplasty for proximal humerus fracture between 2011 and 2018. Patients were stratified based on biological sex. Patient demographics, comorbidities, and 30-day perioperative complication rates were collected. Univariate analyses and multiple variable logistic regression modeling were performed.

Results

About 905 patients were included in the analysis—175 (19.3%) were male and 730 (80.7%) were female. Males were more likely to sustain perioperative complications (26.3% vs. 14.1%; P < .001)—pneumonia (2.9% vs. 0.5%; P = .016), unplanned intubation (2.3% vs. 0.4%; P = .029), and unplanned reoperation (9.1% vs. 1.1%; P < .001). On multivariate analysis, males were at a 2.4-fold increase risk of developing any complication (OR = 2.38 [95% CI 1.55-3.65]; P < .001) and a 10-fold increase risk of returning to the operating room for an unplanned reoperation (OR = 10.59 [95% CI 4.23-27.49]; P < .001) compared with females.

Conclusion

Females were more likely to undergo reverse shoulder arthroplasty for proximal humerus fracture, but males were at increased risk of sustaining short-term complications. This study provides useful information for clinicians to consider when counseling their patients during the perioperative period.

Mortality after a proximal humeral fracture

Aims

The aims of this study were to investigate the mortality following a proximal humeral fracture. Data from a large population-based fracture register were used to quantify 30-day, 90-day, and one-year mortality rates after a proximal humeral fracture. Associations between the risk of mortality and the type of fracture and its treatment were assessed, and mortality rates were compared between patients who sustained a fracture and the general population.

Methods

All patients with a proximal humeral fracture recorded in the Swedish Fracture Register between 2011 and 2017 were included in the study. Those who died during follow-up were identified via linkage with the Swedish Tax Agency population register. Age- and sex-adjusted controls were retrieved from Statistics Sweden and standardized mortality ratios (SMRs) were calculated.

Results

A total of 18,452 patients who sustained a proximal humeral fracture were included. Their mean age was 68.8 years (16 to 107) and the majority (13,729; 74.4%) were women. A total of 310 (1.68%) died within 30 days, 615 (3.33%) within 90 days, and 1,445 (7.83%) within one year after the injury. The mortality in patients sustaining a fracture and the general population was 1,680/100,000 and 326/100,000 at 30 days, 3,333/100,000 and 979/100,000 at 90 days, and 7,831/100,000 and 3,970/100,000 at one year, respectively. Increasing age, male sex, low-energy trauma, type A fracture, concomitant fractures, and non-surgical treatment were all independent factors associated with an increased risk of mortality.

Conclusion

Compared with the general population, patients sustaining a proximal humeral fracture have a significantly higher risk of mortality up to one year after the injury. The risk of mortality is five times higher during the first 30 days, diminishing to two times higher at one year, suggesting that these patients constitute a strikingly frail group, in whom appropriate immediate management and medical optimization are required.

Comparability of Patient-reported Outcome Measures and Clinical Assessment Tools for Shoulder Function in Patients with Proximal Humeral Fracture

BACKGROUND

Patient-reported outcome measures (PROMs) are gaining increasing importance in the context of quality management. Different PROMs and scoring tools are available to assess shoulder function after proximal humeral fracture (PHFx). In Europe, these include the Constant-Murley Score (CS), Neer Score (NS), Oxford Shoulder Score (OSS), University of California at Los Angeles Score (UCLA) and Disabilities of the Arm, Shoulder and Hands Score (DASH). In addition, the health-related quality of life can be assessed by the PROMs Short Form 36 (SF-36) and EuroQol (EQ-5D). Although all these test instruments assess shoulder function, the components to be answered objectively and subjectively vary and thus the possibility of independent assessment. The aim of the present study is to compare the correlation between the results of the different PROMs and the clinical screening tools in patients with PHFx.

METHODS

76 patients who were treated with angular stable plate osteosynthesis for a proximal humeral fracture between 01/2001 and 12/2005 were included in this trial. The outcome was measured with PROMs or clinical scoring tools such as CS, NS, OSS, UCLA, DASH, SF-36 and EQ-5D and a correlation coefficient between those evaluation tools was calculated. In addition, a distinction was made between the two force measurement methods (wrist [HG] vs. deltoid muscle [DM]) for CS.

RESULTS

The correlation of the results of CS and NS (HG: r = 0.85; p < 0.001/DM: r = 0.93; p < 0.001), CS and UCLA (HG: r = 0.83; p < 0.001/DM: r = 0.86; p < 0.001), NS and UCLA (r = 0.91; p < 0.001) as well as DASH and OSS (r = 0.88; p < 0.001) was strongly expressed. A good comparability of the results was demonstrated between CS and OSS (HG: r = 0.63; p < 0.001/DM: r = 0.66; p < 0.001) and between CS and DASH (HG: r = 0.62; p < 0.001/DM: r = 0.61; p < 0.001). The correlation of CS (HG/DM) and UCLA with the EQ-5D index was also good. Assessment of the physical components of SF-36 with CS, NS, OSS, UCLA and DASH showed a moderate to good association, while the mental components of SF-36 showed a low correlation (p > 0.05).

CONCLUSION

The assessment of shoulder function after proximal humerus fracture showed a very strong correlation within the clinical questionnaires (CS/NS/UCLA) and the PROMs (OSS/DASH). A strong correlation also exists between the clinical questionnaires and the PROMs. There was only a moderate correlation with the EQ-5D. The moderate to strong correlation between the physical components of SF-36, with almost no correlation between the mental components of SF-36, indicates that the quality of life restriction is based on a physical, but not on a mental impairment.

Mortality after a proximal humeral fracture

AIMS

The aims of this study were to investigate the mortality following a proximal humeral fracture. Data from a large population-based fracture register were used to quantify 30-day, 90-day, and one-year mortality rates after a proximal humeral fracture. Associations between the risk of mortality and the type of fracture and its treatment were assessed, and mortality rates were compared between patients who sustained a fracture and the general population.

METHODS

All patients with a proximal humeral fracture recorded in the Swedish Fracture Register between 2011 and 2017 were included in the study. Those who died during follow-up were identified via linkage with the Swedish Tax Agency population register. Age- and sex-adjusted controls were retrieved from Statistics Sweden and standardized mortality ratios (SMRs) were calculated.

RESULTS

A total of 18,452 patients who sustained a proximal humeral fracture were included. Their mean age was 68.8 years (16 to 107) and the majority (13,729; 74.4%) were women. A total of 310 (1.68%) died within 30 days, 615 (3.33%) within 90 days, and 1,445 (7.83%) within one year after the injury. The mortality in patients sustaining a fracture and the general population was 1,680/100,000 and 326/100,000 at 30 days, 3,333/100,000 and 979/100,000 at 90 days, and 7,831/100,000 and 3,970/100,000 at one year, respectively. Increasing age, male sex, low-energy trauma, type A fracture, concomitant fractures, and non-surgical treatment were all independent factors associated with an increased risk of mortality.

CONCLUSION

Compared with the general population, patients sustaining a proximal humeral fracture have a significantly higher risk of mortality up to one year after the injury. The risk of mortality is five times higher during the first 30 days, diminishing to two times higher at one year, suggesting that these patients constitute a strikingly frail group, in whom appropriate immediate management and medical optimization are required.

Shoulder arthroplasty for proximal humerus fractures in the elderly: The path from Neer to Grammont

Shoulder replacement is indicated for the surgical treatment of proximal humeral fractures in elderly patients, when severe comminution and osteoporosis jeopardize the chances of success of any fixation technique. Two different implants are available for this purpose: anatomical hemiarthroplasty (HA) and reverse total shoulder arthroplasty (RTSA). HA for fractures was popularized by Charles Neer in the ‘50s and for several decades remained the only reliable implant for these injuries. However, many authors reported inconsistent results with HA as a consequence of the high rate of tuberosity and rotator cuff failure. In 1987, Paul Grammont designed the first successful RTSA, which was the end result of a long thought process on functional surgery of the shoulder. This implant was initially used to treat cuff tear arthropathy and shoulder pseudoparalysis, but indications have gradually expanded with time. Since RTSA does not rely on a functional cuff for shoulder elevation, it was felt that results in fractures could be improved by this prosthesis. In this study, the salient features of these implants are described to understand the rationale behind both approaches and highlight their pros and cons. Several clinical studies comparing HA vs RTSA for proximal humeral fractures have been published during the last two decades. A literature review is carried out to analyze and compare outcomes of both implants, analyzing clinical results, radiographic findings and complications. The final goal is to provide an overview of the different factors to consider for making a choice between these two prostheses.

Indications and results of osteosynthesis for proximal humerus fragility fractures in elderly patients

Proximal humerus fractures (PHF) are common injuries in the elderly population. Conservative treatment is indicated for undisplaced and stable fractures, which account for almost 80% of the cases. More complex fracture patterns might need surgery, with a wide variety of indication criteria and surgical techniques described in the literature. Surgical treatment should be reserved for patients in good clinical conditions, autonomous in daily living activities and able to adhere to postoperative rehabilitation protocols. In the elderly population with severe osteoporosis, cognitive impairment and clinical comorbidities, the risk of surgical failures is high. In these patients, the choice between surgical and conservative treatment, as well as for the type of procedure, is even more difficult, with no general consensus in the literature. Final indication is usually conditioned by surgeon’s experience and preference. Two independent reviewers (B.H and G.G) independently extracted studies on proximal humeral fractures. All selected studies were screened independently (B.H and G.G) based on title and abstract. Then the full text of any article that either judged potentially eligible was acquired and reviewed again. Any disagreement was resolved by discussing the full text manuscripts. Aim of the present paper is to review the literature about indications and results of osteosynthesis for proximal humerus fragility fractures in the elderly population.

Reverse Shoulder Arthroplasty for Proximal Humerus Fracture

PURPOSE OF REVIEW

The purpose of this review is to examine trends, outcomes, and principles in treatment of proximal humerus fractures in the elderly with a critical focus on reverse shoulder arthroplasty as a developing treatment option.

RECENT FINDINGS

Recent literature shows an increase in reverse shoulder arthroplasty and a decrease in hemiarthroplasty performed for proximal humerus fractures. More predictable outcomes and lower revision rates are seen in older individuals treated primarily or secondarily with reverse shoulder arthroplasty compared to those treated with hemiarthroplasty. We report current and historical treatments, outcomes, and principles in reverse shoulder arthroplasty for treatment of complex, displaced proximal humerus fractures in older individuals (≥ 65 years old).

Mortality after inpatient stay for proximal humeral fractures

BACKGROUND

A proximal humeral fracture is well established as a fracture of fragility in elderly patients. However, this injury does not receive the same emphasis on post-injury management as a femoral neck fracture. The objectives of this study were to establish the influence of sustaining a proximal humeral fracture on mortality and to identify the variables predictive of 5-year mortality.

METHODS

Between January 2007 and January 2011, 288 consecutive patients who were admitted after sustaining a proximal humeral fracture were identified from the clinical coding department. Data were retrospectively collected and included patient demographic characteristics, comorbidities, anemia, physical and social independence, length of inpatient stay, management, and mortality.

RESULTS

Of the patients, 13 (4.5%) had died at 1 month; 28 (9.7%), at 3 months; 46 (16.0%), at 1 year; and 117 (40.6%), at 5 years. A Cox proportional hazards regression identified male sex, comorbidities, unemployment or retirement, and nonoperative management as independent predictors of 5-year mortality.

CONCLUSIONS

Elderly patients who require admission after sustaining a proximal humeral fracture are frail and subject to a greater-than-average risk of mortality for their age. The risk of mortality is greater for those of male sex who have comorbidities and a loss of physical and social independence.

Nationwide in-hospital mortality following major fractures among hemodialysis patients and the general population: An observational cohort study

BACKGROUNDS

End-stage kidney disease (ESKD) is associated with increased risk of fracture and subsequent morbidity and mortality. However, fracture site-specific mortality in ESKD patients have yet to be elucidated in comparison with the general population.

METHODS

In this population-based cohort derived from the Diagnosis Procedure Combination database of Japan from 2012 to 2014, we included 9320 ESKD patients undergoing hemodialysis and 547,726 patients without ESKD who were hospitalized for five major fractures, including hip (proximal femur), spine, forearm, upper arm, and leg (distal femur and proximal tibia). Overall and site-specific risks of in-hospital death were determined by logistic regression models.

RESULTS

The age- and sex-adjusted mortality rates were 4.91% (95% confidence interval [CI], 4.46-5.37) and 1.02% (95% CI, 0.99-1.06) in the hemodialysis and general population groups, respectively. The multivariate odds ratio (OR) of death in hemodialysis patients versus the general population was 2.48 (95% CI, 2.25-2.74) for overall fractures, and was particularly high for a subgroup of upper arm fracture (OR 4.82, 95% CI, 3.19-7.28). The site-specific odds of death (95% CI) among hip, spine, forearm, upper arm, and leg (reference) fractures were 1.77 (0.98-3.18), 1.48 (0.79-2.75), 0.19 (0.04-0.86), and 2.01 (1.01-4.01) in hemodialysis patients, and 1.28 (1.13-1.45), 1.00 (0.88-1.14), 0.13 (0.10-0.17), and 0.83 (0.70-0.97) in the general population, respectively.

CONCLUSION

Hemodialysis patients experienced a 4.8-fold higher mortality rate after fractures than the general population. Mortality after upper arm fracture was specifically high in patients on hemodialysis, likely due to the involvement of vascular access located on the fractured arm.

Emergency Orthogeriatrics: Concepts and Therapeutic Considerations for the Geriatric Patient

Appropriate recognition of the physiologic, psychological, and clinical differences among geriatric patients, with respect to orthopedic injury and disease, is paramount for all emergency medicine providers to ensure they are providing high-value care for this vulnerable population.

Long-term mortality after internal fixation of calcaneal fractures: a retrospective study

The aim of this study was to describe the mortality risk after calcaneal fractures which required internal fixation and evaluate predictors of survival. During the observed 11-year period (1995-2006), 178 consecutive patients underwent operative fixation for displaced intra-articular calcaneal fractures. Patient demographics, mechanism of injury, and social deprivation (Carstairs index) were recorded. Mortality was obtained from patient notes. Causes of mortality were obtained from the national database. Standardised mortality ratios (SMRs) were calculated. Ten patients were lost to follow-up. Of the remaining 168 patients, the mean age was 41 (range 14-77) years. Females [n = 33, 46.3 standard deviation (SD) 17.1 years] were significantly (difference 6.5 years, 95% CI 1.1-11.9, p = 0.02) older than male patients (n = 135, 39.8 SD 13.4 years). During the study period, 28 patients died. The overall unadjusted survival rate was 92.8% (95% CI 87.0-98.7) at 10 years and 81.9% (95% CI 76.2-87.6) at 15 years. The SMR at 10 years was 5.2 (95% CI 2.8-13.3) for males and 1.4 (95% CI - 4.9 to 7.8) for females. Cox regression analysis demonstrated male gender to be a significant predictor of mortality (hazard ratio 2.77, 95% 3.83-9.65, p = 0.01) adjusted for age and social deprivation. Male patients requiring internal fixation of intra-articular calcaneal fractures have a significantly increased mortality risk compared to an age- and gender-matched population. Further study is warranted to fully identify the reasons behind this, which may enable their survival to be improved.Level of evidence Retrospective Cohort study, Level 4.

Psychosocial factors affecting variation in patient-reported outcomes after elbow fractures

BACKGROUND

The purpose of this study was to identify factors associated with limitations in function measured by patient-reported outcome measures (PROMs) 6-9 months after elbow fractures in adults from a range of demographic, injury, psychological, and social variables measured within a week and 2-4 weeks after injury.

METHODS

We enrolled 191 adult patients sustaining an isolated elbow fracture and invited them to complete PROMs at their initial visit to the orthopedic outpatient clinic (within a maximum of 1 week after fracture), between 2 and 4 weeks, and between 6 and 9 months after injury; 183 patients completed the final assessment. Bivariate analysis was performed, followed by multivariable regression analysis accounting for multicollinearity. This was evaluated using partial R², correlation matrices, and variable inflation factor assessment.

RESULTS

There was a correlation between multiple variables within a week of injury and 2-4 weeks after injury with PROMs 6-9 months after injury in bivariate analysis. Kinesiophobia measured within a week of injury and self-efficacy measured at 2-4 weeks were the strongest predictors of limitations 6-9 months after injury in multivariable regression. Regression models accounted for substantial variance in all PROMs at both time points.

CONCLUSIONS

Developing effective coping strategies to overcome fears related to movement and reinjury and finding ways of persevering with activity despite pain within a month of injury may enhance recovery after elbow fractures. Heightened fears around movement and suboptimal coping ability are modifiable using evidence-based behavioral treatments.

Mortality Rates of Humerus Fractures in the Elderly: Does Surgical Treatment Matter?

INTRODUCTION

Multiple studies have shown the impact of hip fractures on geriatric mortality. Few evaluate mortality after proximal humerus (PH) or distal humerus (DH) fractures, and fewer determine differences in mortality based on management. We aim to evaluate a statewide cohort of elderly patients with PH or DH fractures to evaluate mortality, length of stay, discharge data, readmission, and differences based on management.

METHODS

The New York Statewide Planning and Research Cooperative System database was used to identify patients 60 years and older admitted with a PH or DH fracture. Patient demographics, including age, gender, sex, race, weight, and insurance status, along with comorbid conditions using the Charlson Comorbidity Index, were determined. Seven-day, 30-day, and 1-year mortality was determined for operative and nonoperative cohorts. Logistic regression determined the competing risk of mortality when controlling for patient demographics, comorbid conditions, and treatment.

RESULTS

Forty-two thousand five hundred eleven PH and 7654 DH fractures were evaluated. PH fractures had higher mortality than DH. Nonoperative treatment occurred in 76.2% of PH fractures and 53% of DH fractures. There were more comorbid conditions, longer length of stay, and higher mortality at 7 days, 30 days, and 1 year in patients treated nonoperatively. After controlling for patient demographics and comorbid conditions, there was no difference in mortality between PH and DH fractures, but operative treatment for either PH or DH was associated with lower mortality at all time points.

DISCUSSION

Fewer PH than DH fractures were treated operatively. Operative treatment was associated with improved survival in patients hospitalized with PH or DH fracture even after controlling for patient demographic and comorbid factors.

Impact of Social Network on the Risk and Consequences of Injurious Falls in Older Adults

OBJECTIVES

A smaller social network is associated with worse health-related outcomes in older people. We examined the impact of social connections and social support on the risk of injurious fall and on fall-related functional decline and mortality.

DESIGN

Prospective study with 6-year follow-up.

SETTING

Community.

PARTICIPANTS

A total of 2630 participants (aged ≥60 years) from the Swedish National Study on Aging and Care in Kungsholmen.

MEASUREMENTS

Social connections (social network size and contact frequency) and social support (social resource perception and satisfaction) were assessed through validated questionnaires. Data on injurious falls (falls requiring inpatient or outpatient care) and mortality came from official registers. We defined injurious falls as severe if they caused fracture and/or intracranial injury and as multiple if two or more occurred during the 6-year follow-up. Functional decline was defined as the loss of ability to perform one or more activities of daily living during the follow-up.

RESULTS

During the follow-up, 322 participants experienced injurious falls. After adjusting for potential confounders, the hazard ratio of injurious falls was 1.7 (95% confidence interval [CI] = 1.1-2.4) for people with poor social connections and 1.5 (95% CI = 1.1-2.1) for people with moderate social connections (reference: rich social connections). Social support was not associated with fall risk. The odds of functional decline among those with severe/multiple falls and (1) poor social connections (odds ratio [OR] = 5.2 [95% CI = 2.1-12.9]) or (2) poor social support (OR = 4.5 [95% CI = 1.7-12.0]) was up to twice as high as among those with severe/multiple falls and (3) rich social connections (OR = 2.5 [95% CI = .9-6.6]) or (4) rich social support (OR = 2.7 [95% CI = 1.2-6.3]). Similar but more attenuated results emerged for mortality.

CONCLUSIONS

Social network may influence fall risk and fall-related functional decline and mortality. J Am Geriatr Soc 67:1851-1858, 2019.

Fragility Fracture Risk in Elderly Patients With Cervical Myelopathy

STUDY DESIGN

Retrospective review.

OBJECTIVE

To identify and compare the incidences of fragility fractures amongst three elderly populations: the general population, patients with surgically treated cervical spondylotic myelopathy (CSM), and patients with CSM not surgically treated.

SUMMARY OF BACKGROUND DATA

CSM is a common disease in the elderly. Progression of myelopathic symptoms, including gait imbalance, can be a source of morbidity as it can lead to increased falls.

METHODS

Records of elderly patients with Medicare insurance from 2005 to 2014 were retrospectively reviewed. Three mutually exclusive populations of patients were identified for analysis, including a cohort of patients with a diagnosis of CSM who were not treated with surgery; a cohort of patients with CSM who were treated with surgery; and a group of control patients who had never been treated with cervical spine surgery nor were diagnosed with CSM. Incidence of fractures of the distal radius, proximal humerus, proximal femur, and lumbar spine were assessed and compared between cohorts, adjusted by age, sex, osteoporosis, dementia, cerebrovascular disease, and Charlson Comorbidity Index.

RESULTS

A total of 891,864 patients were identified, of which 60,332 had a diagnosis of CSM and 24,439 underwent cervical spine surgery. Compared to general population controls, the 12-month adjusted odds of experiencing at least one fragility fracture were 1.59 times higher in patients with CSM who were not treated with surgery (P < 0.001). The analogous odds ratio was 1.34 (P < 0.001) at 3 years. Compared to nonsurgically treated patients with CSM, the odds of experiencing at least one fragility fracture were reduced to 0.89 in surgically treated patients (P = 0.008).

CONCLUSION

Fragility fractures are a significant source of morbidity and mortality in elderly patients. CSM is associated with increased rates of fragility fractures, although surgical management of CSM may be protective against risk of fragility fracture.

Mortality After Complex Displaced Proximal Humerus Fractures in Elderly Patients: Conservative Versus Operative Treatment With Reverse Total Shoulder Arthroplasty

Introduction

Proximal humerus fractures (PHFs) are a common fragility fracture and have been shown to increase mortality in elderly patients. In the last decade, reverse total shoulder arthroplasty (RTSA) was introduced as a reliable operative treatment option for this indication. In other fragility fractures, most notably hip fractures, urgent surgical treatment can reduce mortality. The purpose of this study is to evaluate whether treatment with RTSA can reduce 1-year mortality in elderly patients with complex displaced PHFs.

Materials and Methods

A retrospective study was performed to compare 1-year mortality between 2 groups of elderly patients (>75 years old) who presented to a level 1 trauma center emergency department with complex displaced PHFs. The conservative treatment group (n = 83; mean age, 83.7 years) presented from 2008 to 2010 when RTSA was not yet available, and treatment was nonoperative. The surgical treatment group (n = 62; mean age, 82.2 years) presented from 2012 to 2015 and underwent RTSA.

Results

One-year mortality was 8.1% (male 7.1%; female 8.3%) in the surgical treatment group and 10.8% (male 18.8%; female 9.0%) in the conservative treatment group. The reduction in mortality in the surgical treatment group was not significant (entire cohort P = .56; males P = .35; females P = .59).

Discussion

Recent studies failed to show better functional results after surgical treatment with RTSA when compared to conservative treatment. This study suggests that a benefit of surgical treatment with RTSA that was not examined until now might exist-a reduction in the increased mortality risk associated with PHFs.

Conclusions

There was no significant difference in 1-year mortality between the groups, although there was a trend showing lower mortality with RTSA, mostly in men. Further studies with larger populations and longer follow-up times are needed to determine whether this trend is of clinical significance.

Incidence and outcomes of humeral fractures in the older person

Humeral fractures are not well understood and thus we examined the incidence and outcomes of elderly humeral fractures at a single institution over a 3-year period. We found increasing incidence in humeral fractures with increasing age and negative outcomes comparable to hip fractures.

INTRODUCTION

In this study, we report the incidence of humeral fractures in the older patient and their outcomes, including new nursing homes discharges and mortality, residing in the metropolitan referral area of a Sydney tertiary referral hospital.

METHODS

All admissions between 2013 and 2016, of patients aged 65 years or more, presenting to hospital with humeral fractures were reviewed. The data was explored primarily for outcomes (mortality and new admissions to residential aged care facility) and secondarily for clinical association with humeral fractures.

RESULTS

Two hundred eighty-one episodes of humeral fracture were identified. Incidence peaked in the above 85-year-old group at 670 per 100,000 persons per year. Proximal fractures were accounted for 84.3% of the cohort. 12.8% received operative management. The in-hospital mortality rate was 3.6%. Gender was a significant predictor for mortality (OR = 5.8, 95% CI 1.3-28.5, p value = 0.0032) with males six times more likely to experience in-hospital mortality compared to females. 17.8% of participants were admitted to a new nursing home. Logistical regression demonstrated age (OR = 1.10, 95% CI 1.04-1.17; p value = 0.001) and Charlson comorbidity index (OR = 1.32, 95% CI 1.04-1.66; p value = 0.02) were predictors of admission to a new nursing home.

CONCLUSION

Humeral fractures are common in the older population and cause a substantial amount of new nursing home admissions and mortality. Further study is required to ascertain appropriate guidelines for treatment and rehabilitation.
