Concomitant upper limb fractures and short-term functional recovery in hip fracture patients: does the site of upper limb injury matter?

Cognitive assessment to optimize prediction of functional outcome in subacute hip fracture: a short-term prospective study

BACKGROUND

Cognitive impairment is a long-known negative prognostic factor after hip fracture. Cognition is usually screened by a single easy-to-administer bedside tool, but recent studies have shown that screening tests may be not enough to rule out cognitive impairment with an unfavorable prognostic role. Unfortunately, data on outcome prediction by further cognitive assessments is sparse.

AIM

We focused on patients with subacute hip fracture defined cognitively intact or mildly impaired on the screening evaluation performed by the Short Portable Mental Status Questionnaire (SPMSQ). We hypothesized that each of 3 further cognitive tests could independently predict activities of daily living, with optimal prediction of function obtained by performing all three the tests.

DESIGN

Short-term prospective study.

SETTING

Rehabilitation ward.

POPULATION

Inpatients with subacute hip-fracture.

METHODS

Three cognitive tests were performed on admission to rehabilitation in the patients who made ≤4 errors on the SPMSQ: Montreal Cognitive Assessment (MoCA), Rey Auditory Verbal Learning Test (RAVLT, immediate and delayed recall) and Frontal Assessment Battery (FAB). We assessed activities of daily living by the Barthel index. Successful rehabilitation was defined with a Barthel Index Score ≥85.

RESULTS

Each of the three cognitive tests assessed before rehabilitation significantly predicted the Barthel index scores measured at the end of the rehabilitation course in our sample of 280 inpatients. However, only the MoCA score retained its significant predictive role when the scores from the three tests were included together as independent variables in a multiple regression model, with adjustments for a panel of potential confounders (P=0.007). The adjusted odds ratio to achieve successful rehabilitation for a seven-point change in MoCA score was 1.98 (CI 95% from 1.02 to 3.83; P=0.042).

CONCLUSIONS

Contrary to our hypothesis, MoCA but not RAVLT and FAB retained the prognostic role when the scores from the three tests were evaluated together as potential predictors of functional ability in activities of daily living.

CLINICAL REHABILITATION IMPACT

In the presence of a normal (or mildly altered) score on the SPMSQ in subacute hip fracture, MoCA scores improve prediction of activities of daily living and should be routinely performed.

Concomitant fractures in patients with proximal femoral fractures lead to a prolonged hospital stay but not to increased complication rates or in-house mortality if treated surgically: a matched pair analysis

BACKGROUND

Impact of concomitant fractures on patients sustaining a proximal femur fracture remains unclear. Rising numbers and patient need for rehab is an important issue. The objective of our study was to investigate the impact of concomitant fractures, including all types of fractures, when treated operatively, for proximal femur fractures on the length of hospital stay, in-house mortality and complication rate.

METHODS

Observational retrospective cohort single-center study including 85 of 1933 patients (4.4%) with a mean age of 80.5 years, who were operatively treated for a proximal femoral and a concomitant fracture between January 2016 and June 2020. A matched pair analysis based on age, sex, fracture type and anticoagulants was performed. Patient data, length of hospital stay, complications and mortality were evaluated.

RESULTS

The most common fractures were osteoporosis-associated fractures of the distal forearm (n = 34) and the proximal humerus (n = 36). The group of concomitant fractures showed a higher CCI than the control group (5.87 vs. 5.7 points; p < 0.67). Patients with a concurrent fracture had a longer hospital stay than patients with an isolated hip fracture (15.68 vs. 13.72 days; p < 0.056). Complications occurred more often in the group treated only for the hip fracture (11.8%, N = 20), whilst only 7.1% of complications were recorded for concomitant fractures (p < 0.084). The in-house mortality rate was 2.4% and there was no difference between patients with or without a concomitant fracture.

CONCLUSIONS

A concomitant fracture to a hip fracture increases the length of hospital stay significantly but does not increase the complication rate or the in-house mortality. This might be due to the early mobilization, which is possible after early operative treatment of both fractures.

Does the surgical treatment of concomitant upper limb fractures affect the outcomes of hip fractures in the elderly population?

INTRODUCTION

Elderly patients with concomitant upper limb and hip fractures present a management dilemma because upper limb fractures potentially affect rehabilitation outcomes for the hip fracture. This study aims to evaluate whether the site of upper limb fractures and the decision to surgically treat such fractures affect the functional outcome of surgically treated hip fracture patients.

METHODOLOGY

We retrospectively reviewed 1828 hip fracture patients treated at a single trauma centre over 3 years, of whom 42 with surgically treated hip fractures had concomitant upper limb fractures. Outcome measures, such as length of hospital stay, complications, mortality and readmission rates, were assessed, whilst the functional outcomes were evaluated using the Modified Barthel Index (MBI) on admission, post-operatively and at 6 and 12 months of follow-up.

RESULTS

Amongst the 42 patients with surgically treated hip fractures, 31.0% had proximal humerus fractures, 50.0% had wrist fractures, 16.7% had elbow fractures and 2.4% had forearm fractures. 50.0% of these upper limb fractures were treated surgically. There was no difference in complications, inpatient morbidity, readmission rates or the length of hospital stay for patients whose upper limb fractures were surgically treated as compared to those non-surgically treated. There was no difference in absolute MBI scores at 6 and 12 months based on the management of upper limb fractures. However, patients with surgically treated wrist fractures had statistically significant higher MBI scores at 6 months as compared to those treated non-surgically.

CONCLUSION

Surgical treatment of concomitant upper limb fractures does not appear to change the outcomes of the hip fractures. Hip fracture patients with surgically treated wrist fractures had better functional outcomes at 6 months compared to those treated non-surgically; however, there was no difference at 12 months. Hip fracture patients with concomitant wrist fractures had better functional outcomes compared to hip fracture patients with proximal humerus fractures.

Impact of concomitant upper-extremity injuries in patients with hip fractures: a systematic review and meta-analysis

INTRODUCTION

Combined hip and upper-extremity fractures raise clinical concerns because upper-extremity fractures may hinder early mobilization, thereby affecting rehabilitation and mortality. This systematic review and meta-analysis aimed to evaluate the effects of combined upper-extremity and hip fractures on rehabilitation and mortality.

MATERIALS AND METHODS

We systematically searched MEDLINE, Embase, and the Cochrane Library for studies published before March 20, 2022, that evaluated the impact of concomitant upper-extremity injuries in geriatric patients with hip fractures. The pooled analysis identified differences in the (1) length of hospital stay, (2) discharge destination, and (3) mortality rates between the isolated and combined hip fracture groups.

RESULTS

A total of 217,233 patients with isolated hip fractures (n = 203,816) and combined hip and upper-extremity fractures (n = 13,417) from 12 studies were analyzed. The average length of hospital stay was significantly longer in the combined upper-extremity fracture group than in the isolated hip fracture group (mean difference = 1.67 days; 95% confidence interval [CI] 0.63-2.70; P = 0.002). Patients in the combined upper limb fracture group were less likely to be discharged directly home (odds ratio [OR] = 0.64; 95% CI 0.52-0.80; P < 0.001) and showed significantly higher 30-day mortality (OR = 1.44; 95% CI 1.32-1.58; P < 0.001). The mortality rate after 30 days was not significantly different between the two groups.

CONCLUSIONS

Concomitant upper-extremity fractures have debilitating effects on rehabilitation and early mortality in geriatric patients with hip fractures. Therefore, more focus should be placed on the early ambulation of patients with hip fractures and simultaneous upper limb fractures to promote rehabilitation and alleviate the public health burden.

LEVEL OF EVIDENCE

III meta-analysis.

Greater length of hospital stay for concurrent hip and upper limb fractures compared to isolated hip fractures: a systematic review of 13 studies including 210,289 patients and meta-analysis

BACKGROUND

The impact of concurrent upper limb and fragility hip fractures has not been well defined. A greater understanding of this can guide decision making in the early peri-operative period and subsequent rehabilitation of such patients.

AIMS

To identify if patients with concurrent upper limb and fragility hip fractures have different outcomes and demographics than those with an isolated hip fracture.

METHODS

A search of MEDLINE and EMBASE was performed to identify cohort and case-control studies, comparing concurrent hip and upper limb fractures with isolated hip fractures. Meta-analysis was conducted using RevMan 5.4. Subgroup analyses were performed for concurrent distal radius and concurrent proximal humerus fractures.

RESULTS

13 studies were included reporting on 196,916 patients with an isolated hip fracture and 13,373 with concurrent hip and upper limb fractures. Patients with concurrent upper limb fractures had a significantly longer length of hospital stay (mean difference: 3.97 days, 95% CI: 1.36, 6.57, P=0.003) as compared to those with isolated hip fractures. Patients with concurrent upper limb fractures were significantly more likely to be female (OR: 0.57, 95% CI: 0.46, 0.70, P<0.00001), reside at home pre-injury (OR: 0.6, 95% CI: 0.37, 0.96, P=0.03) and have no cognitive impairment (OR: 0.54, 95% CI: 0.35, 0.84, P=0.006). Patients with concurrent distal radius fractures had significantly lower 90-day mortality (OR: 0.70, 95% CI: 0.49, 0.99, P=0.04) and 1-year mortality (OR: 0.68, 95% CI: 0.51, 0.90, P=0.008).

CONCLUSIONS

Concurrent fragility hip and upper limb fractures are associated with increased length of hospital stay. We recommend early, aggressive, individualised rehabilitation to help improve outcomes and early hospital discharge in this highly vulnerable patient group.

Simultaneous hip and upper-limb fractures are associated with lower Geriatric Nutritional Index scores than isolated hip fractures: a cross-sectional study of 858 women

BACKGROUND AND AIMS

Factors associated with simultaneous fractures at hip and upper limb have scarcely been investigated. Our aim was to assess the association between Geriatric Nutritional Risk Index (GNRI) scores and concurrent upper-limb fractures in women with a fall-related hip fracture.

METHODS

We investigated 858 of 907 women admitted to our Physical and Rehabilitation Medicine ward following a fall-related hip fracture.

RESULTS

GNRI scores were significantly lower in the 41 women with a simultaneous upper-limb fracture than in the 817 with an isolated hip fracture: median (interquartile range) were 85.9 (80.6-94.1) ad 90.3 (83.4-98.0), respectively, in the two groups (p = 0.021). After adjustment for age, height, body mass index, 25-hydroxyvitamin D, parathyroid hormone, femoral-neck bone mineral density, cognitive impairment, neurologic impairment and type of hip fracture we confirmed a significant association between GNRI scores and the concomitant upper-limb fractures (p = 0.001). The adjusted odds ratio for suffering a concomitant fracture was 7.53 (95% CI from 1.79 to 31.72; p = 0.006) for the 190 women of the GNRI lowest class (GNRI score < 82) versus the 213 women of the highest class (GNRI score > 98).

CONCLUSIONS

Data show that GNRI scores were significantly lower in the subgroup of women with hip fracture and concurrent upper-extremity fracture than in the controls with isolated hip fracture. Although caution is needed in interpreting our results due to the cross-sectional design of the study, we suggest that low GNRI scores may have a role in the genesis of the concurrent fractures.

Predictors of Exceeding Target Inpatient Rehabilitation Length of Stay After Hip Fracture

OBJECTIVE

The aim of the study was to identify factors associated with exceeding a target inpatient rehabilitation length of stay of 28 days or less for individuals with hip fracture.

DESIGN

Retrospective cohort study of hip fracture patients admitted to an urban Canadian inpatient rehabilitation facility between January 1, 2013, and January 1, 2018. Patient characteristics previously shown to be associated with individual outcomes and/or length of stay after hip fracture were extracted from the institution's data warehouse. Regression models were used to examine factors associated with exceeding target length of stay as well as overall length of stay.

RESULTS

Four hundred ninety-three subjects were included in the analysis. Three hundred forty-five (70%) met and 148 (30%) exceeded their target length of stay. Patients who exceeded their target were more likely to be elderly (odds ratio, 1.05; 95% confidence interval, 1.02-1.08), to live alone prefracture (odds ratio, 1.72; 95% confidence interval, 1.02-2.91), to have dementia (odds ratio, 2.79; 95% confidence interval, 1.12-6.97), and higher admission pain scores (severe pain odds ratio, 2.51; 95% confidence interval, 1.06-5.93). Higher admission motor Functional Independence Measure scores (odds ratio, 0.95; 95% confidence interval, 0.92-0.98) were protective.

CONCLUSIONS

Advancing age, having dementia, living alone prefracture, and reporting moderate or severe pain at the time of admission not only increased the odds of an individual exceeding their target length of stay but also was associated with an overall increase in length of stay. Conversely, having a higher admission motor Functional Independence Measure score was protective.

Concurrent upper limb and hip fracture in the elderly

AIMS

To present a large series of concurrent upper limb and hip fracture in the elderly treated at a United Kingdom major trauma centre.

PATIENTS AND METHODS

Prospective data collection was performed for all elderly patients admitted to a single centre with hip fracture between January 2006 and November 2015. Comparative analysis of concurrent upper limb and hip fracture and an isolated hip fracture was performed.

RESULTS

Study cohort included 307 patients that had sustained concurrent upper limb and hip fracture and 6887 with an isolated hip fracture. A concurrent upper limb fracture was associated with increased length of stay (21.7 vs. 18.8 days, p = 0.003) and decreased proportion of patients returning to their own home at discharge (39.2% vs. 49.4%, p = 0.001). No differences in age, Abbreviated Mental Test (AMT), Nottingham Hip Fracture Score (NHFS) and mortality were identified. However, concurrent wrist fracture 365-day mortality was lower than that of isolated hip fracture (20.9% vs 29.2%, p = 0.018). Concurrent humerus fracture was associated with increased inpatient death (13.7% vs 6.4%, p = 0.046) and 365-day mortality (34.7% vs 20.9%, p = 0.014) compared to concurrent wrist fracture. Surgical stabilisation of the concurrent upper limb fracture was performed in 90 wrist (52.3%) and 13 humerus (13.7%) cases. Operative management of the concurrent fracture did not yield significant differences in acute hospital length of stay or rehabilitation requirement. Cox regression analysis of 365-day survival data demonstrated that age, NHFS, AMT, gender and presence of a concurrent upper limb fracture independently influence 365-day mortality rate.

CONCLUSION

There are increased rehabilitation requirements for elderly patients with concurrent upper limb and hip fractures. There is a marked distinction in survivorship outcomes for patients sustaining concurrent wrist and concurrent humerus fractures.

CLINICAL RELEVANCE

Demonstrates increased rehabilitation requirements in concurrent upper limb and hip fracture in the elderly Highlights concurrent humerus fracture as a high risk group.

Simultaneous Hip and Distal Radius Fractures-Does It Make a Difference with Respect to Rehabilitation?

INTRODUCTION

A minority of patients with hip fractures sustain concomitant wrist fractures. Little is known about the rehabilitation outcome in this group of patients.

AIM OF STUDY

Prospective investigation of functional outcome and survival in patients with combined hip and wrist fractures compared with patients who sustain an isolated hip fracture.

METHODS

341 patients who presented with an acute hip fracture during a 12 month period were included in the study. Outcome at discharge and 4 months follow-up was compared between patients with isolated hip fractures and those patients who sustained simultaneous distal wrist fractures.

RESULTS

The actual incidence of concurrent hip and wrist fractures in our cohort was 4.7%. Patients who sustained a concurrent hip and wrist fracture showed no differences regarding short- and long-term functional outcome and survival.

CONCLUSION

Our results imply that patients with simultaneous hip and wrist fractures have no difference in rehabilitative outcome. Future studies should further investigate the distinctive characteristics of this patient subgroup.

Association between patients' state upon admission and decline in activities of daily living

[Purpose] In this study, we aimed to determine the components of activities of daily living that decline easily during hospitalization. [Participants and Methods] We performed a prospective cohort study of 2,819 inpatients who were hospitalized and discharged. We prospectively evaluated the Barthel Index at admission and discharge, age, length of hospital stay, clinical department, and rehabilitation type. We divided the inpatients into two groups based on the Barthel Index score at admission and compared the items of the index at admission and discharge to analyze the characteristics of decline in activities of daily living. [Results] Forty-nine inpatients (2.0%) had declined in activities of daily living. There were no significant between-group differences in age, length of hospital stay, clinical department, or ratio of individual rehabilitation. However, transfer and toilet use remarkably decreased in the group with Barthel Index scores at admission <85, and bathing and ascending/descending remarkably decreased in the group with Barthel Index at admission ≥85. [Conclusion] The characteristics of decrease in each activity of daily living vary, and our results suggested the components that easily declined when inpatients were divided based on their performance of activities of daily living at admission.

Predictors of mortality in the elderly patient with a fracture of the odontoid process

Aims

Fracture of the odontoid process (OP) in the elderly is associated with mortality rates similar to those of hip fracture. The aim of this study was to identify variables that predict mortality in patients with a fracture of the OP, and to assess whether established hip fracture scoring systems such as the Nottingham Hip Fracture Score (NHFS) or Sernbo Score might also be used as predictors of mortality in these patients.

Patients and Methods

We conducted a retrospective review of patients aged 65 and over with an acute fracture of the OP from two hospitals. Data collected included demographics, medical history, residence, mobility status, admission blood tests, abbreviated mental test score, presence of other injuries, and head injury. All patients were treated in a semi-rigid cervical orthosis. Univariate and multivariate analysis were undertaken to identify predictors of mortality at 30 days and one year. A total of 82 patients were identified. There were 32 men and 50 women with a mean age of 83.7 years (67 to 100).

Results

Overall mortality was 14.6% at 30 days and 34.1% at one year. Univariate analysis revealed head injury and the NHFS to be significant predictors of mortality at 30 days and one year. Multivariate analysis showed that head injury is an independent predictor of mortality at 30 days and at one year. The NHFS was an independent predictor of mortality at one year. The presence of other spinal injuries was an independent predictor at 30 days. Following survival analysis, an NHFS score greater than 5 stratified patients into a significantly higher risk group at both 30 days and one year.

Conclusion

The NHFS may be used to identify high-risk patients with a fracture of the OP. Head injury increases the risk of mortality in patients with a fracture of the OP. This may help to guide multidisciplinary management and to inform patients. This paper provides evidence to suggest that frailty rather than age alone may be important as a predictor of mortality in elderly patients with a fracture of the odontoid process.

Remote Injuries and Outcomes After Distal Radius Fracture Management

BACKGROUND

Distal radius fracture (DRF) is a common fracture of the upper extremity. The role of concurrent injuries in patients treated for DRFs is poorly elucidated. The authors sought to determine whether remote injuries were associated with worse outcomes after management of DRFs.

METHODS

A retrospective cohort study including all consecutively seen patients by a university hospital hand service between 2010 and 2015. Preoperative radiographs were analyzed, and patients were managed by surgeon preference and evaluated postoperatively using pain scores. Remote injury was defined as any other injury sustained at the time of fracture not localized to affected extremity. Univariate analysis was performed to identify factors associated with risk of complication. A multivariate logistic regression analysis was performed, controlling for confounding factors.

RESULTS

A total of 181 DRFs in 176 patients were treated over the 5-year period of the study. Forty-eight (26.5%) of the fractures were managed nonoperatively with casting, 12 (6.6%) with closed reduction and pinning, and 119 (65.7%) with open reduction and plating. The mean follow-up was 5.2 months. The complication rate was 18.2%. The most common complication was persistent pain in 5 patients, followed by median neuropathy, loss of reduction, arthritis, and distal radioulnar joint instability. After controlling for age, body mass index, hand surgeon, and other confounders, remote injury was associated with a significantly increased risk of complications ( P = .04, odds ratio: 6.03, 95% confidence interval: 1.05-34.70).

CONCLUSIONS

Patients with remote injuries have a 6-fold increased risk of complications after DRF treatment. The additional risk in these patients should be considered during patient/family counseling and clinical decision-making in DRF management.

Lean Mass and Functional Recovery in Men With Hip Fracture: A Short-Term Prospective Pilot Study

OBJECTIVE

The aim of the study was to assess the capability of different definitions of low appendicular lean mass (aLM) to predict the short-term functional recovery in men with hip fracture.

DESIGN

We investigated 80 of 95 men with hip fracture admitted consecutively to a rehabilitation hospital. Body composition was assessed by dual-energy x-ray absorptiometry. Functional recovery after inpatient rehabilitation was evaluated using Barthel Index scores.

RESULTS

The patients with aLM above the cutoff value of 19.75 kg indicated by the Foundation for the National Institutes of Health (FNIH) had significantly higher Barthel Index scores than those with aLM below the cutoff value (P = 0.002). Patients' categorization according to the same threshold (aLM = 19.75 kg) was significantly associated with a Barthel Index score of 85 or higher after adjustment for age, cognitive impairment, hip fracture type, co-morbidities, and medications (odds ratio = 7.17, 95% confidence interval = 1.43-35.94, P = 0.017). Conversely, patients' categorization according to neither Baumgartner's cutoff value (7.26 kg/m(2)) for aLM/height(2) nor Foundation for the National Institutes of Health cutoff value (0.789) for aLM divided by body mass index was significantly associated with the Barthel Index scores.

CONCLUSIONS

Categorization according to the Foundation for the National Institutes of Health threshold for aLM, but not to the Foundation for the National Institutes of Health threshold for aLM/body mass index or Baumgartner's threshold for aLM/height, was associated with the short-term recovery in activities of daily living after a hip fracture in men.

Clinical assessment of patients with isolated hip fractures associated with an upper limb fracture

INTRODUCTION

Some patients with a hip fracture also present a concomitant upper limb fracture. We want to know whether these patients have a worse functional level and whether they have any differences in various clinical parameters compared with patients with an isolated hip fracture.

MATERIAL AND METHODS

We retrospectively reviewed 1061 discharge reports from the Orthogeriatrics Unit. We collected information on several clinical parameters of the fractures. Subsequently, we performed a statistical analysis of the data by comparing the associated fracture group with the isolated fracture group.

RESULTS

We detected 44 patients with associated upper limb fracture, 90.9% were women (40) and the average age was 84.45years. Eighty-one point eight percent of the upper limb fractures were distal radius or proximal humerus. Pertrochanteric fractures were the most common (none of them were subtrochanteric fractures). Surgical delay was 2.60days and the average hospital stay was 12.30days. Sixty-four point three percent were nail surgery and 31% arthroplasty. The mean Barthel index score was 84.88 (P=.021). Fifty-two point 5 percent of the patients in the study group were referred to a functional support unit (P=.03). The in-hospital mortality rate was 4.2%, with no differences between groups.

CONCLUSIONS

Patients with an associated fracture have a higher previous functional capacity and they are more independent. Nevertheless, after the fracture they need more help from the healthcare system for optimal functional recovery.

Incidence of bone protection and associated fragility injuries in patients with proximal femur fractures

OBJECTIVES

Our aim was to investigate whether patients presenting with fragility fractures of the proximal femur are receiving osteoporosis treatment and to assess the number of other fragility fractures they have sustained prior to admission.

METHODS

All patients presenting to our institution with fragility fractures of the proximal femur within an 18-month period (January 2012-August 2013) were included. Patient demographics; fracture classification (AO/OTA); American Society of Anesthesiologists (ASA) grade; Abbreviated Mental Test Score (AMTS) on admission; type of operation; time to operation; peri-operative complications; length of hospital stay (LOS); walking status; osteoporotic medication; Dual-energy X-ray absorptiometry (DEXA) results; additional fragility fractures; and mortality were collected and analysed.

RESULTS

A total of 1004 patients (278 male) met the inclusion criteria and were included into the study. The mean age was 82.01 years and mean LOS was 19.54days. Fifty-four per cent of the patients were admitted from their own homes whereas 43% were capable to walk indoors without any aids before their injury. Mean time to surgery was 2.06days (Median: 1.31, range: 0-26days). Three hundred and six patients (30.5%) had at least another fragility fracture before the index episode (mean 1.40 fractures; SD: 0.71 fractures; range: 1-6 fractures). Only 16.4% were under complete osteoporosis treatment on admission, defined as receiving calcium with vitamin D and a bisphosphonate or an alternative agent. When we compared patients without a history of a previous fragility fracture (Group A) and patients with at least another previous fragility fracture (Group B), we found that patients in Group B had a significantly lower AMTS score, lower bone mineral density (BMD) as evident on the DEXA scan, an inferior mobility before admission and a higher incidence of extracapsular fractures (p<0.05). On discharge, patients in Group B had a higher chance of receiving complete bone protection compared to group A (27.9% versus 41.7%; p<0.01). Following discharge, 11.2% of the patients sustained an additional fragility fracture. The mean time from the index episode to the additional fracture was 0.65 years, whilst these injuries were more frequent in Group B (RR=1.638; p<0.05).

CONCLUSION

Patients presenting with a hip fracture are generally under-treated for osteoporosis. Post-operative assessment by a designated geriatrician and use of a standardised protocol is of paramount importance for reducing the risk of additional fragility fractures. Additionally, screening of the elderly population for identifying the patients who suffer from osteoporosis can potentially reduce the risk of sustaining a further fragility fracture.

Handgrip strength is an independent predictor of functional outcome in hip-fracture women: a prospective study with 6-month follow-up

The objective of this study was to investigate the contribution of handgrip strength in predicting the functional outcome after hip fracture in women.We prospectively investigated white women (N = 193 of 207) who were consecutively admitted to a rehabilitation hospital after a hip fracture. We measured handgrip strength with a Jamar dynamometer (Lafayette Instrument Co, Lafayette, IN), on admission to rehabilitation. Ability to function in activities of daily living was assessed by the Barthel index both on discharge from rehabilitation and at a 6-month follow-up.We found significant correlations between handgrip strength measured before rehabilitation and Barthel index scores assessed both on discharge from rehabilitation (ρ = 0.52, P < 0.001) and after 6 months (ρ = 0.49, P < 0.001). Significant associations between handgrip strength and Barthel index scores persisted after adjustment for age, comorbidities, pressure ulcers, medications in use, concomitant infections, body mass index, hip-fracture type, and Barthel index scores assessed both preinjury and on admission to rehabilitation (P = 0.001). Further adjustments for both Barthel index scores and Timed Up-and-Go test assessed at rehabilitation ending did not erase the significant association between handgrip strength and the Barthel index scores at the 6-month evaluation (P = 0.007). To define successful rehabilitation, we categorized the Barthel index scores as either high (85 or higher) or low (<85). The adjusted odds ratio for 1 SD increase in grip strength was 1.73 (95% confidence interval [CI] 1.05-2.84, P = 0.032) for having a high Barthel index score at the end of inpatient rehabilitation and 2.24 (95% CI 1.06-5.18) for having a high Barthel index score at the 6-month follow-up.Handgrip strength assessed before rehabilitation independently predicted the functional outcome both after inpatient rehabilitation and at a 6-month follow-up in hip-fracture women.
