Quality of life and femoral neck fractures

Early Postoperative Weight-Bearing Ability after Total Hip Arthroplasty versus Bipolar Hemiarthroplasty in Elderly Patients with Femoral Neck Fracture

Background: Femoral neck fractures are among the most common types of fractures and particularly affect elderly patients. Two of the most common treatment strategies are total hip arthroplasty (THA) and bipolar hemiarthroplasty (BA). However, the role of the different treatment strategies in the postoperative weight-bearing ability in the early postoperative phase is still not entirely clear. Methods: Patients who underwent either THA or BA were consecutively included in our prospective cohort study. Gait analysis was performed during the early postoperative period. The gait analysis consisted of a walking distance of 40 m coupled with the turning movement in between. During the gait analysis, the duration of the measurement, the maximum peak force and the average peak force were recorded. Results: A total of 39 patients were included, 25 of whom underwent BA and 14 of whom underwent THA. The maximum peak force during the gait analysis was, on average, 80.6% ± 19.5 of the body weight in the BA group and 78.9% ± 21.6 in the THA group. The additionally determined average peak force during the entire gait analysis was 66.8% ± 15.8 of the body weight in the BA group and 60.5% ± 15.6 in the THA group. Conclusions: Patients with femoral neck fractures undergoing THA and BA can achieve sufficient weight bearing on the operated leg in the early postoperative period. In our study, BA did not allow for a significantly higher average and maximum loading capacity compared with THA.

Does a hip fracture mean we should we operate on a concomitant proximal humerus fracture?

BACKGROUND

Concomitant upper extremity and hip fractures present a challenge in postoperative mobilization in the geriatric population. Operative fixation of proximal humerus fractures allows for upper extremity weight bearing. This retrospective study compared outcomes between operative and non-operative proximal humerus fracture patients with concomitant hip fractures.

METHODS

A trauma database of 13,396 patients age > 55 years old was queried for concomitant hip and proximal humerus fracture patients between 2014-2021. Medical records were reviewed for demographics, hospital quality measures, Neer classification, morphine milligram equivalents (MME), and outcomes. All hip fractures were treated operatively. Patients were grouped based on operative vs. non-operative treatment of their proximal humerus fracture. Primary outcomes included comparing postoperative ambulatory status, pain, length of stay (LOS), intensive care unit (ICU) need, discharge disposition, and readmission rates.

RESULTS

Forty-eight patients (0.4%) met inclusion criteria. Twelve patients (25%) underwent operative treatment for their proximal humerus fracture and 36 (75%) received non-operative treatment. Patients with operative fixations were younger (p < 0.01), had more complex Neer classifications (p = 0.031), more likely to be community ambulators (p < 0.01), and required more inpatient MMEs (p < 0.01). There were no differences in LOS (p = 0.415), need for ICU (p = 0.718), discharge location (p = 0.497), 30-day readmission (p = 0.228), or 90-day readmission (p = 0.135) between cohorts. At 6 months postoperatively, among community or household ambulators, a higher percentage of operative patients returned to their baseline ambulatory functional status, however, this was not significant (70% vs. 52%, p = 0.342). There were three deaths in the non-operative cohort and no deaths in the operative cohort.

CONCLUSION

Patients with hip fractures and concomitant proximal humerus fractures treated operatively required more inpatient MMEs and trended toward maintaining baseline ambulatory function. There were no differences in inpatient LOS, ICU need, discharge location, or readmissions. Future larger, multicenter studies are needed to further delineate if operative repair of concomitant proximal humerus fractures provides a benefit in the geriatric population.

Evaluation of quality of life and associated factors in patients with intertrochanteric femoral fracture

BACKGROUND

Intertrochanteric fracture is a common injury among the elderly, causing fundamental lifestyle derangements, influencing the patients' social and psychological functioning. We aimed to study the quality of life (QoL) and its different parameters in patients with this type of injury.

MATERIALS AND METHODS

In this cross-sectional study, all patients hospitalized with intertrochanteric fracture aged above 50 from 2020 to 2022 at the Shahid Beheshti Hospital in Babol, Iran, were included. Patients were primarily managed surgically and, in exceptional cases non-surgically, were followed up for at least 12 months after receiving treatment. During the follow-up period, patients were dialled and completed a questionnaire to assess the patient's QoL by the 36-item Short Form Health Survey (SF-36). QoL parameters were analyzed based on patients' sex, age, type of treatment, and height of fall causing fracture.

RESULT

A total number of 200 patients, including 101 (50.5%) males and 99 (49.5%) females, with a mean age of 74.76±11.36 years (range: 50-99), were included. Regarding the received treatment, 192 (96.0%) patients underwent surgery, and 8 (4.0%) underwent non-surgical treatment. In the study of SF-36 scores, the mean score of male patients was 42.31±14.58, and females scored 37.83±15.35, and the difference was statistically significant (P = 0.04). The mean score of QoL and its subscales among the 50-75 group patients was significantly higher than the 76-99 group (P<0.001). The average score of QoL was considerably higher in patients who had surgery (40.75±14.57) compared to those who had non-surgical treatment (24.30±19.85) (P = 0.01). Patients having a fall from a higher height had higher QoL after treatment.

CONCLUSION

This study revealed that patients with an intertrochanteric femoral fracture had poor QoL in all aspects. The overall QoL was significantly higher among male patients, younger patients, those who underwent surgical treatment, and the falls from higher heights. These findings highlight the necessity of long-term follow-up and support in patients with intertrochanteric fractures.

Radiologic blind spots in hip and pelvic radiographs

PURPOSE

The purpose of our study was to identify the locations at which hip and pelvic fractures are commonly missed on radiographs.

METHODS

A retrospective study was performed at four non-Level 1 trauma center emergency departments. IRB approval was obtained. All emergency department hip or pelvic radiographs with subsequent CT performed within 48 h were identified from 2017 to 2022. Reports for each radiograph and CT were scored for the presence or the absence of fracture in the following locations: ilium, sacrum, superior pubic ramus, inferior pubic ramus, pubis, acetabulum, subcapital femoral, femoral neck, greater trochanter, lesser trochanter, intertrochanteric, and subtrochanteric. The CT report was used as the gold standard. The false-negative radiography cases were reviewed on a PACS workstation to determine whether the case had an "unexpected miss" of a fracture, a subtle fracture, radiographically occult fracture, or exam was limited by artifact. The percentage of missed fractures at each location was calculated.

RESULTS

Nine hundred seventy-five radiography cases with subsequent CT were identified. One hundred forty-six cases did not meet entry criteria; therefore, 829 cases were analyzed further. Seventy-four percent of patients were female with age of 74 ± 16 (mean ± standard deviation) years (range 1-103). Three hundred fifty-two cases had at least one fracture, and many cases had multiple fractures. There were 68 false-negative cases. The most commonly missed fractures by percentage were pubis, ilium, and greater trochanter. The most common unexpectedly missed fractures were greater trochanter and femoral subcapital.

CONCLUSION

A careful systematic evaluation of hip and pelvic radiographs, with particular attention to the pubis, ilium, greater trochanter, and subcapital region, may improve radiographic fracture detection and decrease delays in diagnosis.

Developing a Modeling Framework for Quantifying the Health and Cost Implications of Antibiotic Resistance for Surgical Procedures

Background. Antimicrobial resistance (AMR) is a global public health threat. The wider implications of AMR, such as the impact of antibiotic resistance (ABR) on surgical procedures, are yet to be quantified. The objective of this study was to produce a conceptual modeling framework to provide a basis for estimating the current and potential future consequences of ABR for surgical procedures in England. Design. A framework was developed using literature-based evidence and structured expert elicitation. This was applied to populations undergoing emergency repair of the neck of the femur and elective colorectal resection surgery. Results. The framework captures the implications of increasing ABR by allowing for higher rates of surgical site infection (SSI) as the effectiveness of antibiotic prophylaxis wanes and worsened outcomes following SSIs to reflect reduced antibiotic treatment effectiveness. The expert elicitation highlights the uncertainty in quantifying the impact of ABR, reflected in the results. A hypothetical SSI rate increase of 14% in a person undergoing emergency repair of the femur could increase costs by 39% (-2% to 108% credible interval [CI]) and decrease quality-adjusted life-years by 11% (0.4% to 62% CI) over 15 y. Conclusions. The modeling framework is a starting point for addressing the implication of ABR on the outcomes and costs of surgeries. Due to clinical uncertainty highlighted in the expert elicitation process, the numerical outputs of the case studies should not be focused on but rather the framework itself, illustration of the evidence gaps, the benefit of expert elicitation in quantifying parameters with limited data, and the potential magnitude of the impact of ABR on surgical procedures. Implications. The framework can be used to support research surrounding the health and cost burden of ABR in England.

Highlights

The modeling framework is a starting point for assessing the health and cost impacts of antibiotic resistance on surgeries in England.Formulating a framework and synthesizing evidence to parameterize data gaps provides targets for future research.Once data gaps are addressed, this modeling framework can be used to feed into overall estimates of the health and cost burden of antibiotic resistance and evaluate control policies.

Complications following total hip arthroplasty and hemiarthroplasty for femoral neck fractures in patients with a history of lumbar spinal fusion

INTRODUCTION

The purpose of this study was to examine whether previous lumbar spinal fusion (LSF) was an independent risk factor for complications in patients undergoing total hip arthroplasty (THA) or hemiarthroplasty for displaced femoral neck fractures.

METHODS AND MATERIALS

An administrative database was queried from 2010 to Q2 of 2019 to analyze and compare complications in patients undergoing either THA or hemiarthroplasty for femoral neck fracture with a history of LSF versus no history of LSF. Joint complications including periprosthetic fracture, prosthetic joint infection (PJI), prosthetic joint dislocation (PJD), aseptic loosening, and prosthetic revision were examined at 90 days and 1 year post-operatively.

RESULTS

In the THA cohort, patients with prior LSF had significantly higher likelihood of aseptic loosening at 90 days and 1 year post-operatively in comparison to those without prior LSF (90-day: OR 2.22; 1-year: OR 1.95). Patients in the hemiarthroplasty cohort with prior LSF had significantly higher likelihood of PJI (90-day: OR 2.18; 1-year: OR 2.37), aseptic loosening (90-day: OR 3.42; 1-year: OR 4.68), and prosthetic revision (90-day: OR 2.27; 1-year: OR 2.25) in both the 90-day and 1-year postoperative period in comparison to those without prior LSF. Additionally, for the same cohort, periprosthetic fracture (1-year: OR 2.32) and PJD (1-year: OR 2.31) were significantly higher at 1-year postoperative.

CONCLUSION

Presence of LSF was found to be an independent risk factor for increased joint complications in patients undergoing either a THA or hemiarthroplasty for displaced femoral neck fractures.

Trochanteric Femur Fractures: Application of Skeletal Traction during Surgery Does Not Alter Soft-Tissue Microcirculation

Background and Objectives: Wound infections provoked by alterations in microcirculation are major complications in the treatment of trochanteric femur fractures. Surgical fracture fixation on a traction table is the gold standard for treatment, but the effect on tissue microcirculation is unknown. Microcirculation could be impaired by the pull on the soft-tissue or by a release of vasoactive factors. We hypothesized that intraoperative traction impairs soft-tissue microcirculation. Materials and Methods: In 22 patients (14 women, eight men), average age 78 years (range 36–96 ± 14), with trochanteric femur fractures, non-invasive laser-Doppler spectrophotometry was used to assess oxygen saturation, hemoglobin content, and blood flow in the skin and subcutaneous tissue before and after application of traction. Measurements were recorded in nine locations around the greater trochanter at a depth of 2, 8, and 15 mm before and after fracture reduction by traction. Results: No differences were found in any depth with traction compared to without (oxygen saturation: p = 0.751, p = 0.308, and p = 0.955, haemoglobin content: p = 0.651, p = 0.928, and p = 0.926, blood flow: p = 0.829, p = 0.866, and p = 0.411). Conclusion: In this pilot study, the application of traction does not affect skin and subcutaneous microcirculation in the surgery of proximal femur fractures.

Delayed Presentation of Patients with Hip Fractures during the COVID-19 "Stay-at-Home" Order in the Southmost Region of the United States

To evaluate the effects of COVID-19 and stay-at-home orders in traumatic hip fractures presentation, we conducted a retrospective chart review cohort study from March 13 to June 13 in 2020 compared to 2019 from a single-hospital Trauma Level 2 Center. Males and females, 18 years of age and older presenting with a diagnosis of displaced or nondisplaced, intracapsular, or extracapsular hip fracture, underwent standard of care—comparative analysis of the patient's characteristics and clinical outcomes. The primary study outcomes included age, sex, ethnicity, and body mass index, the onset of injury, date of arrival, payer, the primary type of injury and comorbidities, mechanism of injury, treatment received, postoperative complications, days in an intensive care unit (ICU), discharge disposition, pre- and postinjury functional status, and COVID-19 test. Age, sex, ethnicity, and body mass index were similar in the patients in 2019 compared to 2020. The patients' average age was 76 years old, 80% reported Hispanic ethnicity, and 63% of the patients were females. Most injuries (90%) occurred due to falls. On average, patients in 2020 presented 4.8 days after the injury onset as compared to 0.7 days in 2019 (p < 0.05). There was an increase in displaced fractures in 2019 compared to 2020 and an increase in patients' disposition into rehabilitation facilities compared to skilled nursing facilities. Despite the delay in presentation, length of stay, days in the ICU, or functional outcomes of the patients were not affected. Although the patients showed a delayed presentation after hip fracture, this does not appear to significantly interfere with the short-term or the 6-month mortality outcomes of the patients, suggesting the possibility of guided delayed care during times of national emergency and increased strain in hospital resources.

Quality of life in elderly people after a hip fracture: a prospective study

BACKGROUND

Hip fracture is an important social and medical problem due to its increasing prevalence, the consequences for health and the economic impact on the health care system, but there is no doubt that it also has repercussions on health-related quality of life (HRQoL). Hence the importance of understanding and determining the impact of the condition on everyday life from the perspective of the patient's physical, emotional and social well-being.

PURPOSE

To determine the impact of hip fracture on HRQoL of people over the age of 65 1 month after surgery, related factors and the effects on functional ability and mood.

METHODS

Prospective observational study conducted in the traumatology units of two university hospitals in the province of Cáceres with consecutive sampling of all patients over the age of 65 admitted for hip fracture surgery during the study period. Sociodemographic and clinical data were recorded at the time of admission and prospectively at the follow-up visit 1 month later. Clinical, social, quality of life (EQ-5D-), basic functional and instrumental capacity (Barthel Index (BI) and Lawton & Brody Scale), and geriatric depression (Yesavage) variables were collected.

RESULTS

The study included 224 patients with a median age of 84.6 years (SD ± 6.1), 76.3% were female. Charlson's comorbidity was 5.3 (SD ± 1.2). The EQ-5D index decreased from 0.62 (SD ± 0.35) to 0.16 at 1 month follow up (SD ± 0.20) p <  0.001. The mean Visual Analog Scale (VAS) score of EQ-5D decreased from 72.8 (SD ±15.8) to 48.3 (SD ± 17.2) p <  0.001. All dimensions of EQ-5D showed a significant reduction from the time of pre-fracture status to 1 month after surgery. Independent factors associated with HRQoL 1 month after surgery were pre-fracture status Barthel Index score, Lawton and Brody scale, presence of depression, and type of surgery.

CONCLUSIONS

After a hip fracture, patients experience considerable deterioration in their HRQoL, especially in self-care, daily activities, and mobility. There is also a significant decline in functional capacity for both the basic and instrumental activities of daily living. One month after surgery, HRQoL is a long way from pre-fracture levels.

Less than one-third of hip fracture patients return to their prefracture level of instrumental activities of daily living in a prospective cohort study of 480 patients

AIM

A significant loss of instrumental activities of daily living (IADL) after a hip fracture has been reported. The aim of the present study was to identify specific predictors for low IADL after a hip fracture, in order to target better postoperative care for these patients.

METHODS

A prospective observational cohort study of 480 hip fracture patients was carried out. IADL was measured at baseline, and after 3 and 12 months using the Groningen Activity Restriction Scale. Multivariable logistic regression analysis was carried out using age, sex, American Society of Anesthesiologists classification, prefracture living with a partner, prefracture living situation, prefracture use of walking aids, type of fracture, type of anesthesia, length of hospital stay, postoperative complications and prefracture IADL as potential predictors for low IADL after a hip fracture. The correlation between IADL, mobility and living situation, both at admission, and 3 and 12 months postoperatively, were measured.

RESULTS

Three months after hip fracture treatment, 24% of patients returned to their baseline IADL level, at 12 months postoperative this was 29%. Factors associated with a larger loss in IADL after a hip fracture were older age, prefracture living with a partner, prefracture living at home, prefracture use of walking aids and longer length of hospital stay. The correlation between IADL and living situation was 0.69, and between IADL and use of walking aids was 0.80.

CONCLUSIONS

A return to prefracture IADL level was low. Healthier patients have a steeper decline in postoperative IADL. Geriatr Gerontol Int 2018; 18: 1244-1248.

Femoral neck pseudoarthrosis in a polio patient treated with closed reduction and cell therapy

Poliomyelitis disease affects the anterior horns cells of the spinal cord and certain motor nuclei of the brain stem. Paralysis type is flaccid and asymmetrical and result in muscular imbalance.

Due to this, in case of having a hip muscles involvement, degenerative or posttraumatic, total hip arthroplasty is normally contraindicated because of the excessive risk of hip dislocation. In cases of subcapital femoral neck fractures the femoral head vascularization is a main concern, and in cases of neglected fracture with pseudoarthrosis the vascular status to the head must be investigated prior to further decisions.

We report the case of a femoral neck fracture non-union after a missed femoral neck fracture in a polio affected leg treated with cannulated screws and percutaneous autologous injection of processed total nuclear cells (TNC) mixed with putty demineralized bone matrix.

Hip Fracture Treatment in Oulu — One-Year Survey with Four-Month Follow-Up

Backgrounds and Aims:

The standardized forms of the Standardized Audit of Hip Fractures in Europe (SAHFE) are aimed for the evaluation of hip fracture treatment in different hospitals and countries. The purpose was to evaluate and characterize a cohort of hip fracture patients with these forms and to evaluate their value in quality control.

Material and Methods:

The non-pathological hip fractures in patients over 49 years of age treated in the Oulu University Hospital were prospectively recorded during a one-year period using SAHFE forms.

Results:

There were 238 (52 male and 186 female) patients with a mean age of 78 (50–102) years. Fifty-nine percent of the patients were admitted from their own homes. Fifty-seven percent were able to walk alone outdoors and 48% could walk without walking aids before the fracture. A hundred and fifty patients had cervical fractures and 88 trochanteric fractures. The most frequent treatment of cervical fractures was Austin-Moore hemiarthroplasty (68%) and that of trochanteric fractures Gamma nail fixation (86%). At four months after the fracture, 50% lived in their own homes, 33% could walk alone out-doors and 13% could walk without any aids. Thirty-two percent had no pain in the hip. The overall mortality at four months was 17.6% and that of the operated patients 16.2%. The reoperation rate was 8.5%.

Conclusion:

SAHFE forms were very useful in the evaluation of the quality of the hip fracture treatment.

Prediction of Reoperation of Femoral Neck Fractures Treated With Cannulated Screws in Elderly Patients

BACKGROUND

Reoperation of femoral neck fractures in elderly patients is frequent. Our aim was to determine predictors of reoperations following primary internal fixation with 3 cannulated screws.

MATERIALS AND METHODS

A follow-up study included all patients aged 65+ years old patients consecutively admitted to an orthopedic ward with femoral neck fracture in the period from January 1, 2007, to December 31, 2010, and fixed with cannulated screws. We retrospectively obtained all available data from patient databases related to potential predictors of reoperations: gender, age, dwelling, dementia, body mass index, vitamin D, albumin, prednisolone treatment, walking aid, performance of activities of daily living, low-energy trauma, initial displacement, and surgery quality. Outcome was reoperation due to fixation failure/prominent screws, nonunion, or avascular necrosis of femoral head within 2 years after surgery. By multivariate Cox proportional hazards regression, including mortality as a competing risk, we estimated crude and adjusted hazards ratios (HRs) with 95% confidence intervals (CIs) for reoperation.

RESULTS

Two years after surgery, 29% of 322 elderly patients underwent reoperation. Reoperation was associated with primary fracture displacement (HRadjusted 1.61; 95% CI: 1.01-2.55; P = .04) compared to undisplacement. A poor quality of primary reduction was associated with a higher risk of reoperations than a good quality (HRadjusted 1.95; 95% CI: 1.02-3.72; P = .04). Elderly individuals in own homes and sheltered housings had a higher risk of reoperation (HRadjusted 2.67; 95% CI 1.35-5.31; P = .005) compared to nursing home residents.

CONCLUSION

Our findings support the evidence of a higher incidence of reoperation in displaced femoral neck fractures compared to the nondisplaced and is associated with poor quality of fracture reduction. Reoperations are most frequent in younger and more independent patients living at home.

Displaced intracapsular neck of femur fractures in the elderly: bipolar hemiarthroplasty may be the treatment of choice; a case control study

Management of the mobile elderly patient who sustains an intra-capsular neck of femur fracture remains controversial. Current evidence is mixed as to whether total hip arthroplasty (THA), which confers higher surgical and dislocation risk, is significantly superior in function and in reduced rates of reoperation when compared to bipolar hemi-arthroplasty. A group of 110 patients with an intra-capsular NOF fracture who had undergone either THA or Bipolar hemi-arthroplasty and were still alive at the time of follow up were retrospectively identified and matched using the National Hip Fracture Database. Matching criteria included ASA, age, sex, pre-op mobility, pre-op AMTS and source of admission. Follow up was by postal questionnaire. Mean follow up was 24 months in both groups (Range; Bipolar 12-36 months, THA 12-38 months). There was no significant difference in pre-operative Tonnis grade, postoperative Oxford Hip Score (OHS) or Short Form 36 (SF-36) scores between the two groups. 12 dislocations in 5 patients occurred in the THA group and none in the bipolar group. 33/55 Bipolar patients were discharged to their own home compared to 35/55 in the THA group. None of the bipolar hemi-arthroplasties were revised to THA. Higher complication rates were experienced in the THA group with no increase in function.

Three-Dimensional Reconstruction Modeling of the Spatial Displacement, Extent and Rotational Orientation of Undisplaced Femoral Neck Fractures

The purpose of this study was to employ a new three-dimensional (3D) reconstruction and modeling method to measure displacement of undisplaced femoral neck fractures (Garden stages I and II). We also aimed to evaluate the effectiveness of the Garden classification for determining the displacement of undisplaced femoral neck fractures. A total of 120 consecutive patients with undisplaced femoral neck fractures were enrolled between 2012 and 2014, including 60 within the Garden I group and 60 within the Garden II group. The displacements of the femoral head center (d1) and the lowest point of the fovea capitis femoris (d2) and rotational displacement of the femoral head (α) in the 3D model were measured with 3D computed tomography reconstruction and modeling. Five observers, trauma surgeons, were asked to found the centers of the femoral heads and the deepest points of the foveae. The intraobserver and inter-observer agreements were calculated using Fleiss' kappa. The inter-observer and intra-observer kappa values were 0.937 and 0.985, respectively. Current method has good reliability. We discovered that many participants in our study had been misclassified by an anterior-posterior radiograph as having an "incomplete" fracture. In incomplete fracture of Garden stage I group, the average displacements d1 and d2 were 3.69 ± 1.77 mm and 14.51 ± 1.91 mm, respectively. The mean α was 4.91° ± 2.49°. For impacted fracture of Garden stage I, significant spatial displacement in the impacted fractures was observed (d1: 6.22 ± 3.36 mm; d2: 10.30 ± 5.73 mm; and α: 17.83° ± 10.72°). Similarly, significant spatial displacement was observed among the Garden stage II group (d1: 7.16 ± 4.58 mm; d2: 12.95 ± 8.25 mm; and α: 18.77° ± 9.10°). There was no significant difference in α, d1, and d2 between impacted fracture and Garden stage II groups (P > 0.05). However, significant differences were found between incomplete fracture and Garden stage II groups (P < 0.05). Our findings suggest that 3D reconstruction and modeling may be a better tool for assessing femoral neck fractures than the Garden classification. Undisplaced femoral neck fractures showed variable degrees of displacement and were not undisplaced, stable fractures. Garden classification for undisplaced femoral neck fractures has certain limitations.

Young femoral neck fractures: are we measuring outcomes that matter?

INTRODUCTION

Femoral neck fractures in younger aged patients are particularly devastating injuries with profound impairments of quality of life and function. As there are multiple differences in patient and injury characteristics between young and elderly femoral neck fracture patients, the geriatric hip fracture literature is unlikely to be generalisable to patients under age 60. We conducted a systematic review to determine if clinically relevant outcome measures have been used in previously published clinical studies of internal fixation in young adults with femoral neck fractures.

METHODS

We conducted a comprehensive literature search using multiple electronic databases and conference proceedings to identify studies which used internal fixation for the management of femoral neck fractures in patients between the ages of 15 to 60. Eligibility screening and data abstraction were performed in duplicate. We classified the reported outcomes into the following categories: operative and hospital outcomes, radiographic outcomes, clinical outcomes, and functional outcomes and health-related quality of life. We calculated the frequencies of reported outcomes.

RESULTS

Fort-two studies met our inclusion criteria. Operative and hospital outcomes were poorly reported with less than one-quarter of studies reporting relevant data. Important radiographic outcomes were also inadequately reported with only one-third of studies reporting the quality of the fracture reduction, and methods for assessment were highly variable. The assessment of avascular necrosis was reported in almost all the included studies (95.2%); however, the assessment of nonunion was only reported in three-quarters of the studies. Re-operations were reported in 73.8% of the included studies and the assessment of fracture healing was only reported in two-thirds of the studies. Less than half of the studies reported functional outcomes or health-related quality of life (overall patient evaluation scales and systems (45.2%), patient functional outcomes (30.9%), and health-related quality of life (4.8%).

DISCUSSION

Our systematic review found that the assessment of clinically relevant outcomes in the young femoral neck fracture literature is lacking, which makes utilising the literature to guide clinical practice challenging. Future studies should aim to include important radiographic measures, fracture-healing complications, functional outcomes, and health-related quality of life during any assessment of young femoral neck fracture treatment.

Unstable hip arthroplasties. A prospective cohort study on seventy dislocating hips followed up for four years

PURPOSE

Dislocating hip prosthesis remains a substantial clinical problem. The aim of this study is to describe the risk of recurrent instability after a primary dislocation of primary hip arthroplasty performed for osteoarthritis (OA) or femoral neck fracture (FNF).

METHODS

Seventy patients (male/females: 25/45; mean age 77 [range 46-94]) with dislocating hip arthroplasties were included in a prospective cohort study and followed for four years. Radiographs and all surgical records were reviewed. We compared stable hips to those who either continued to dislocate or were revised due to recurrent instability (unstable group).

RESULTS

Forty-two hips (60 %) had episodes of recurrent instability leading to repeated closed reductions or major revision surgery and were classified as unstable. A diagnosis of FNF and cognitive dysfunction (OR 9.3 [95 % CI 1.4-64.1]) or postoperative radiological discrepancies such as leg-lengthening and offset reduction increased the risk of further instability (OR 13.5 [95 % CI 1.3-148.1]). The surgical approach at primary surgery and ASA class did not significantly influence the risk of continued instability.

CONCLUSIONS

Patients with a FNF and cognitive dysfunction or with sub-optimal postoperative radiographs after hip arthroplasty surgery are at high risk of recurrent instability after a primary dislocation. For hip fracture patients, all efforts should be made to avoid the first dislocation.

Anabolic steroids for rehabilitation after hip fracture in older people

BACKGROUND

Hip fracture occurs predominantly in older people, many of whom are frail and undernourished. After hip fracture surgery and rehabilitation, most patients experience a decline in mobility and function. Anabolic steroids, the synthetic derivatives of the male hormone testosterone, have been used in combination with exercise to improve muscle mass and strength in athletes. They may have similar effects in older people who are recovering from hip fracture.

OBJECTIVES

To examine the effects (primarily in terms of functional outcome and adverse events) of anabolic steroids after surgical treatment of hip fracture in older people.

SEARCH METHODS

We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (10 September 2013), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, 2013 Issue 8), MEDLINE (1946 to August Week 4 2013), EMBASE (1974 to 2013 Week 36), trial registers, conference proceedings, and reference lists of relevant articles. The search was run in September 2013.

SELECTION CRITERIA

Randomised controlled trials of anabolic steroids given after hip fracture surgery, in inpatient or outpatient settings, to improve physical functioning in older patients with hip fracture.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected trials (based on predefined inclusion criteria), extracted data and assessed each study's risk of bias. A third review author moderated disagreements. Only very limited pooling of data was possible. The primary outcomes were function (for example, independence in mobility and activities of daily living) and adverse events, including mortality.

MAIN RESULTS

We screened 1290 records and found only three trials involving 154 female participants, all of whom were aged above 65 years and had had hip fracture surgery. All studies had methodological shortcomings that placed them at high or unclear risk of bias. Because of this high risk of bias, imprecise results and likelihood of publication bias, we judged the quality of the evidence for all primary outcomes to be very low.These trials tested two comparisons. One trial had three groups and contributed data to both comparisons. None of the trials reported on patient acceptability of the intervention.Two very different trials compared anabolic steroid versus control (no anabolic steroid or placebo). One trial compared anabolic steroid injections (given weekly until discharge from hospital or four weeks, whichever came first) versus placebo injections in 29 "frail elderly females". This found very low quality evidence of little difference between the two groups in the numbers discharged to a higher level of care or dead (one person in the control group died) (8/15 versus 10/14; risk ratio (RR) 0.75, 95% confidence interval (CI) 0.42 to 1.33; P = 0.32), time to independent mobilisation or individual adverse events. The second trial compared anabolic steroid injections (every three weeks for six months) and daily protein supplementation versus daily protein supplementation alone in 40 "lean elderly women" who were followed up for one year after surgery. This trial provided very low quality evidence that anabolic steroid may result in less dependency, assessed in terms of being either dependent in at least two functions or dead (one person in the control group died) at six and 12 months, but the result was also compatible with no difference or an increase in dependency (dependent in at least two levels of function or dead at 12 months: 1/17 versus 5/19; RR 0.22, 95% CI 0.03 to 1.73; P = 0.15). The trial found no evidence of between-group differences in individual adverse events.Two trials compared anabolic steroids combined with another nutritional intervention ('steroid plus') versus control (no 'steroid plus'). One trial compared anabolic steroid injections every three weeks for 12 months in combination with daily supplement of vitamin D and calcium versus calcium only in 63 women who were living independently at home. The other trial compared anabolic steroid injections every three weeks for six months and daily protein supplementation versus control in 40 "lean elderly women". Both trials found some evidence of better function in the steroid plus group. One trial reported greater independence, higher Harris hip scores and gait speeds in the steroid plus group at 12 months. The second trial found fewer participants in the anabolic steroid group were either dependent in at least two functions, including bathing, or dead at six and 12 months (one person in the control group died) (1/17 versus 7/18; RR 0.15, 95% CI 0.02 to 1.10; P = 0.06). Pooled mortality data (2/51 versus 3/51) from the two trials showed no evidence of a difference between the two groups at one year. Similarly, there was no evidence of between-group differences in individual adverse events. Three participants in the steroid group of one trial reported side effects of hoarseness and increased facial hair. The other trial reported better quality of life in the steroid plus group.

AUTHORS' CONCLUSIONS

The available evidence is insufficient to draw conclusions on the effects, primarily in terms of functional outcome and adverse events, of anabolic steroids, either separately or in combination with nutritional supplements, after surgical treatment of hip fracture in older people. Given that the available data points to the potential for more promising outcomes with a combined anabolic steroid and nutritional supplement intervention, we suggest that future research should focus on evaluating this combination.

Total hip arthroplasty for hip fractures: 5-year follow-up of functional outcomes in the oldest independent old and very old patients

INTRODUCTION

This study aimed to determine the dislocation and reoperation rate, functional outcomes, and the survival rate of the unique subset of very old but lucid and independent patients with hip fractures following a total hip arthroplasty (THA) and geriatric team-coordinated perioperative care.

METHOD

Between 2000 and 2006, previously independent ambulatory patients ≥80 years old presenting with an intracapsular hip fracture were given THAs under the care of an integrated orthopedic surgery-geriatric service. Their fracture-related complications, ambulation, mental status, and survival were followed for 5 to 11 years postinjury.

RESULTS

Five years postinjury, 57 (61.3%) patients of the original study group were living. In all, 3 (3.2%) patients had postoperative hip dislocations (and 2 patients had dislocation twice) and 2 reoperations were needed within the first postoperative month. There were no hip dislocations or reoperations after the first year. Radiographs obtained on 88% of the surviving patients at 5 years postoperatively showed that all remained unchanged from their immediate postoperative images. Nearly half of the patients were still able to ambulate as they did preoperatively and their mixed-model equation was statistically unchanged.

CONCLUSION

This study of patients >80 years old with previously good functional status demonstrates that with appropriate surgical (best prosthesis, good operating technique, and regional anesthesia) and geriatric (pre- and postoperative assessments, close follow-up, medication adjustments, and fall-prevention instruction) care, they have few hip dislocations and reoperations, survive postfracture at least as long as their noninjured contemporaries, and continue to function and ambulate as they did prior to their injury.

Primary total hip arthroplasty versus internal fixation in displaced fracture of femoral neck in sexa- and septuagenarians

BACKGROUND

The optimal treatment of femoral neck fracture in the elderly patient is still under debate. In patients aged 60-80 years, the decision between internal fixation and arthroplasty remains controversial. The primary aim of the present study is to evaluate the functional outcome of patients aged 60-80 years with femoral neck fracture treated with total hip arthroplasty or closed reduction and internal fixation. The secondary aim is to evaluate the incidence of nonunion and avascular necrosis in femoral neck fracture in different age groups.

MATERIALS AND METHODS

We studied 100 patients affected by displaced fracture of the femoral neck from May 2007 through June 2010. There were 60 men and 40 women with mean age of 66 years. Fifty patients were treated with closed reduction and internal fixation with cannulated screws (group A), and the other 50 patients with total hip arthroplasty (group B). Mean surgical time, blood loss, duration of hospital stay, Harris hip score, complications, and need for reoperation were recorded.

RESULTS

Harris hip score was significantly higher in group B at 3-, 6-, 12-, and 18-month follow-up evaluation. The overall complication rate was 28 % in group A and 32 % in group B, which was not statistically significant. A statistically significant difference was found regarding patients who required reoperation in group A (20 %) compared with group B (no one). The average Harris hip score in the internal fixation group was 90.6 and in the total hip arthroplasty group was 93.7, which was statistically significant (p < 0.05). Our study showed an increased risk for intracapsular hip fracture developing nonunion with older age.

CONCLUSIONS

Primary total hip arthroplasty compared with internal fixation appears to be a reasonably safe method of treating displaced fracture of femoral neck in elderly patients. We also concluded that outcome regarding hip function is generally better after total hip arthroplasty compared with internal fixation.

LEVEL OF EVIDENCE

Level II-Prospective cohort study.

The natural history of the hemiarthroplasty for displaced intracapsular femoral neck fractures

BACKGROUND

Numerous papers have been published on the medium- and long-term results of hemiarthroplasties (HAs) after femoral neck fracture in the elderly. We were not aware of any articles that describe the outcome of HA until the patient dies.

METHODS

Between 1975 and 1989, 307 bipolar hemiarthroplasties were performed in 302 consecutive patients with a displaced femoral neck facture. Patients with osteoarthritis of the hip, rheumatoid arthritis (RA), or senile dementia were not included in the study. All patients were followed annually until they died or until they needed a revision operation.

RESULTS

The mortality rate was 28% after 1 year, and 63% after 5 years. The last patient who did not need a revision operation died in October 2010. Revision operations for aseptic loosening, protrusion, or both had to be performed in 34 patients (16%). A difference in reoperation rate was observed between patients less than 75 years of age (38%) and those who were older (6%).

INTERPRETATION

Apart from age below 75 years, male sex appeared to be predictive of a revision operation. HA is a safe and relatively inexpensive treatment for patients over 75 years of age with a displaced femoral neck fracture.

A comparison of hemiarthroplasty with a novel polycarbonate-urethane acetabular component for displaced intracapsular fractures of the femoral neck: a randomised controlled trial in elderly patients

We undertook a randomised controlled trial to compare bipolar hemiarthroplasty (HA) with a novel total hip replacement (THR) comprising a polycarbonate-urethane (PCU) acetabular component coupled with a large-diameter metal femoral head for the treatment of displaced fractures of the femoral neck in elderly patients. Functional outcome, assessed with the Harris hip score (HHS) at three months and then annually after surgery, was the primary endpoint. Rates of revision and complication were secondary endpoints. Based on a power analysis, 96 consecutive patients aged > 70 years were randomised to receive either HA (49) or a PCU-THR (47). The mean follow-up was 30.1 months (23 to 50) and 28.6 months (22 to 52) for the HA and the PCU group, respectively. The HHS showed no statistically significant difference between the groups at every follow-up. Higher pain was recorded in the PCU group at one and two years' follow-up (p = 0.006 and p = 0.019, respectively). In the HA group no revision was performed. In the PCU-THR group six patients underwent revision and one patient is currently awaiting re-operation. The three-year survival rate of the PCU-THR group was 0.841 (95% confidence interval 0.680 to 0.926). Based on our findings we do not recommend the use of the PCU acetabular component as part of the treatment of patients with fractures of the femoral neck.

Health related quality of life, reoperation rate and function in patients with diabetes mellitus and hip fracture--a 2 year follow-up study

INTRODUCTION

Diabetes mellitus confers an increased risk of hip fractures. There is a limited knowledge of how the outcome after a hip fracture in patients with diabetes affect Health Related Quality of Life (HRQoL). The primary aim of this study was to evaluate HRQoL. Secondary aims were reoperation rate, complications and functions in patients with diabetes followed for 2 years after a hip fracture.

MATERIALS AND METHODS

Out of 2133 patients diabetes was present in 234 patients (11%). Main outcome measurements were HRQoL evaluated with EuroQoL 5-Dindex score, reoperation rate, surgical and medical complications, function as walking ability, daily activities, living condition and pain.

RESULTS

Preoperatively, patients with diabetes mellitus had more pain (p=0.044), co-morbidities, reduced health status (p=0.001) and more often used a walking frame (p=0.014) than patients without diabetes, whereas Katz ADL index, cognition and body mass index did not differ. There was no difference in fracture type, surgical method or reoperation between the two groups or between patients with insulin treated or oral treated diabetes. The EQ-5Dindex score decreased from 0.64 at admission to 0.45 at 4 months, 0.49 at 12 months and 0.51 at 24 months with similar results for patients with and without diabetes. During the first postoperative year there was not more medical complications among patients with diabetes, however cardiac (p=0.023) and renal failure (p=0.032) were more frequent in patients with diabetes at 24 months. Patients with diabetes more often had severe hip pain at 4 months (p=0.031). At 12 months more diabetic patients were living independently (p=0.034). There was no difference in walking ability, ADL and living condition between the groups at 24 months.

CONCLUSION

The findings of this study indicate that patients with diabetes mellitus had more pain, co-morbidities, reduced health status preoperatively than patients without diabetes. Hip fracture patients with diabetes mellitus have more hip pain at 4 months. Cardiac and renal failure was more frequent in patients with diabetes at 24 months but otherwise we found a comparable re-operation rate, function and deterioration of Health Related Quality of Life as patients without diabetes within 2 years after a hip fracture.

Subcapital fractures: a changing paradigm

Options for the treatment of subcapital femoral neck fractures basically fall into two categories: internal fixation or arthroplasty (either hemiarthroplasty or total hip arthroplasty). Historically, the treatment option has been driven by a diagnosis-related approach (non-displaced neck fractures versus displaced neck fractures). More recently, the traditional paradigm has changed. Instead of a diagnosis-related approach, it has become more of a patient-related approach. Treatment options take in to consideration the patient's age, functional demands, and individual risk profile. A simple algorithm can be helpful in terms of directing the treatment. Non-displaced fractures, regardless of age of the patient, should be treated with closed reduction and internal fixation. For displaced femoral neck fractures, the treatment differs depending on the age of the patient. The younger patient should be treated with urgent ORIF with the goal of an anatomic reduction. For displaced femoral neck fractures in the elderly, cognitive function should be determined. For those who are cognitively functioning, total hip arthroplasty appears to be the best option. In the cognitively dysfunctional, a bipolar hemiarthroplasty or a total hip arthroplasty with use of larger heads (32 mm or 36 mm) and/or constrained sockets are a viable option.

Surgical preferences of patients at risk of hip fractures: hemiarthroplasty versus total hip arthroplasty

BACKGROUND

The optimal treatment of displaced femoral neck fractures in patients over 60 years is controversial. While much research has focused on the impact of total hip arthroplasty (THA) and hemiarthroplasty (HA) on surgical outcomes, little is known about patient preferences for either alternative. The purpose of this study was to elicit surgical preferences of patients at risk of sustaining hip fracture using a novel decision board.

METHODS

We developed a decision board for the surgical management of displaced femoral neck fractures presenting risks and outcomes of HA and THA. The decision board was presented to 81 elderly patients at risk for developing femoral neck fractures identified from an osteoporosis clinic. The participants were faced with the scenario of sustaining a displaced femoral neck fracture and were asked to state their treatment option preference and rationale for operative procedure.

RESULTS

Eighty-five percent (85%) of participants were between the age of 60 and 80 years; 89% were female; 88% were Caucasian; and 49% had some post-secondary education. Ninety-three percent (93%; 95% confidence interval [CI], 87-99%) of participants chose THA as their preferred operative choice. Participants identified several factors important to their decision, including the perception of greater walking distance (63%), less residual pain (29%), less reoperative risk (28%) and lower mortality risk (20%) with THA. Participants who preferred HA (7%; 95% CI, 1-13%) did so for perceived less invasiveness (50%), lower dislocation risk (33%), lower infection risk (33%), and shorter operative time (17%).

CONCLUSION

The overwhelming majority of patients preferred THA to HA for the treatment of a displaced femoral neck fracture when confronted with risks and outcomes of both procedures on a decision board.

Proximal femoral fractures in the elderly: how are we measuring outcome?

INTRODUCTION

Patients with proximal femoral fractures present a difficult problem to health care systems in view of their complex presentations and co-morbidities. Traditionally, the focus of outcome measurement for this patient group has been on mortality and surgical implant success. Increasing recognition of the need to diversify outcome measurements has led to the creation and use of a number of outcome scales. We sought to examine how these scales are being used in the current literature.

METHODS

Abstracts to over 4000 papers related to proximal femoral fracture research were screened to identify commonly used scales in the five main categories of general quality of life measures (QoL), Activities of Daily Living scales (ADL), mobility and physical performance scales, disease-specific scales and hip-specific scales. The 14 identified scales were then searched for directly, and papers analysed for scale usage, timing and interpretation.

RESULTS

ADL scales were the most commonly used group, followed by QoL measures, which are validated for elderly patients. Scale timing and use varied widely between studies. A large number of scales were found in addition to the 14 identified scales. None of the 14 identified scales were validated for the proximal femoral fracture population.

DISCUSSION

A good scale must be appropriate in content, method and clinical utility. Its method of application must be reliable, responsive, and validated for the population in question. Outcome scale usage was difficult to assess in proximal femoral fracture research due to difficulties in isolating the relevant research, and in differences in scale timing and interpretation. Scale prevalence was skewed by use by specific research groups.

CONCLUSION

There is no single unifying scale in widespread use for proximal femoral fracture patients. We would recommend the validation of commonly used scales for this population, and would advise the use of scales from more than one category to assess outcome.

Evidence summary: systematic review of surgical treatments for geriatric hip fractures

BACKGROUND

There is a growing body of literature on surgical treatments for elderly patients with a hip fracture and the effects of various surgical procedures on complications and postoperative outcomes. No single review has previously summarized the literature on the effects of surgical procedures on outcomes after treatment across all types of hip fractures. We conducted a comprehensive systematic literature review to organize the clinical evidence for patient-centered outcomes across all types of geriatric hip fractures.

METHODS

We searched MEDLINE, the Cochrane Database of Systematic Reviews, Scirus, and ClinicalTrials.gov for randomized clinical trials and observational studies published between 1985 and 2008. We also manually searched reference lists from relevant systematic reviews.

RESULTS

We found eighty-four [corrected] articles representing seventy-four [corrected] unique, randomized, controlled trials, including thirty-three [corrected] on femoral neck fractures, forty on intertrochanteric fractures, and one on subtrochanteric fractures. Nine observational studies addressed the link between patient characteristics and outcome variables by fracture type. Age, sex, prefracture functioning, and cognitive impairment are related to mortality and functional outcomes. Fracture type does not appear to be independently related to patient outcomes. Mortality, pain, function, and quality of life did not differ by surgical implant class, or by implants within a class. Neither the randomized controlled trials nor the observational literature include the full complement of potential covariates that can impact treatment outcomes after treatment.

CONCLUSIONS

The broader questions about the relationship of patient factors, fracture type, and specific treatments to the outcomes of mortality, functional status, and quality of life cannot be addressed with the existing literature. Research should include comprehensive conceptual models that capture complete sets of important independent variables. Studies of musculoskeletal outcomes, including hip fracture, require well-defined patient groups and consistent use of validated outcome measures.

A comparison of hemiarthroplasty with total hip replacement for displaced intracapsular fracture of the femoral neck: a randomised controlled multicentre trial in patients aged 70 years and over

The aim of this study was to analyse the functional outcome after a displaced intracapsular fracture of the femoral neck in active patients aged over 70 years without osteoarthritis or rheumatoid arthritis of the hip, randomised to receive either a hemiarthroplasty or a total hip replacement (THR). We studied 252 patients of whom 47 (19%) were men, with a mean age of 81.1 years (70.2 to 95.6). They were randomly allocated to be treated with either a cemented hemiarthroplasty (137 patients) or cemented THR (115 patients). At one- and five-year follow-up no differences were observed in the modified Harris hip score, revision rate of the prosthesis, local and general complications, or mortality. The intra-operative blood loss was lower in the hemiarthroplasty group (7% > 500 ml), THR group (26% > 500 ml) and the duration of surgery was longer in the THR group (28% > 1.5 hours versus 12% > 1.5 hours). There were no dislocations of any bipolar hemiarthroplasty than in the eight dislocations of a THR during follow-up. Because of a higher intra-operative blood loss (p < 0.001), an increased duration of the operation (p < 0.001) and a higher number of early and late dislocations (p = 0.002), we do not recommend THR as the treatment of choice in patients aged ≥ 70 years with a fracture of the femoral neck in the absence of advanced radiological osteoarthritis or rheumatoid arthritis of the hip.

Nutritional supplementation for hip fracture aftercare in older people

BACKGROUND

Older people with hip fractures are often malnourished at the time of fracture, and have poor food intake subsequently.

OBJECTIVES

To review the effects of nutritional interventions in older people recovering from hip fracture.

SEARCH STRATEGY

We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (September 2008), the Cochrane Central Register of Controlled Trials (The Cochrane Library 2008, Issue 3), MEDLINE and other major databases (to July 2008).

SELECTION CRITERIA

Randomised and quasi-randomised controlled trials of nutritional interventions for people aged over 65 years with hip fracture.

DATA COLLECTION AND ANALYSIS

Both authors independently selected trials, extracted data and assessed trial quality. We pooled data for primary outcomes.

MAIN RESULTS

Twenty-four randomised trials involving 1940 participants were included. Outcome data were limited and many trials were methodologically flawed. Results from 23 trials are presented here.Ten trials evaluated oral multinutrient feeds: providing non-protein energy, protein, some vitamins and minerals. Oral feeds had no statistically significant effect on mortality (16/244 versus 21/226; risk ratio (RR) 0.76, 95% confidence interval (CI) 0.42 to 1.37) or 'unfavourable outcome' (combined outcome of mortality and survivors with medical complications) (46/126 versus 41/103; RR 0.76, 95% CI 0.55 to 1.04).Four heterogenous trials examining nasogastric multinutrient feeding showed no evidence of an effect on mortality (RR 0.99, 95% CI 0.50 to 1.97). Nasogastric feeding was poorly tolerated.One trial examining nasogastric tube feeding followed by oral feeds found no evidence for an effect on mortality or complications.One trial of multinutrient intravenous feeding followed by oral supplements found a reduction in participants with complications (RR 0.21, 95% CI 0.10 to 0.46), but not in mortality (RR 0.11, 95% CI 0.01 to 2.00).Four trials testing increasing protein intake in an oral feed found no evidence for an effect on mortality (RR 1.42, 95% CI 0.85 to 2.37). Protein supplementation may have reduced the number of long term medical complications.Two trials, testing intravenous vitamin B1 and other water soluble vitamins, or oral 1-alpha-hydroxycholecalciferol (vitamin D) respectively, produced no evidence of effect.One trial, evaluating dietetic assistants to help with feeding, showed no statistically significant effect on mortality (RR 0.57, 99% CI 0.29 to 1.11).

AUTHORS' CONCLUSIONS

Weak evidence exists for the effectiveness of protein and energy feeds. Adequately sized randomised trials with robust methodology are required. In particular, the role of dietetic assistants, and peripheral venous feeding require further evaluation.

Factors determining quality of life and level of sporting activity after internal fixation of an isolated acetabular fracture

We investigated whether patients who underwent internal fixation for an isolated acetabular fracture were able to return to their previous sporting activities.

We studied 52 consecutive patients with an isolated acetabular fracture who were operated on between January 2001 and December 2002. Their demographic details, fracture type, rehabilitation regime, outcome and complications were documented prospectively as was their level and frequency of participation in sport both before and after surgery. Quality of life was measured using the EuroQol-5D health outcome tool (EQ-5D).

There was a significant reduction in level of activity, frequency of participation in sport (both p < 0.001) and EQ-5D scores in patients of all age groups compared to a normal English population (p = 0.001). A total of 22 (42%) were able to return to their previous level of activities: 35 (67%) were able to take part in sport at some level. Of all the parameters analysed, the Matta radiological follow-up criteria were the single best predictor for resumption of sporting activity and frequency of participation.

Cemented versus uncemented hip replacement for fracture of the hip

PURPOSE

Review cemented versus uncemented hemi-arthroplasty hip replacement regarding morbidity and long term results.

METHODS

A literature review searching PubMed and Medline was done. Publications applicable to hip fractures treated by hip replacement or hemi-arthroplasty replacement were reviewed.

RESULTS

Several articles compared cemented femoral stems to fracture fixation. There were few articles comparing cemented and uncemented stems. Some noted increased problems with uncemented stems but did consider design factors. Unreamed tapered stems may have may have fewer problems.

CONCLUSIONS

Prospective studies comparing cemented and uncemented femoral stems are needed to determine the best form of fixation for patients having hip surgery following hip fracture. Tapered uncemented stems may offer as good a result as cemented stems, with less morbidity.

Evaluation of quality of life related to nutritional status

The way in which the quality of life related to health (HRQoL) is affected by the nutritional status of the patient is a subject of constant interest and permanent debate. The purpose of the present paper is to review those studies that relate HRQoL to nutritional status and examine the tools (questionnaires) that they use to investigate this relationship. A critical review of published studies was carried out via an investigation of the following databases: MEDLINE (via PubMed); EMBASE; The Cochrane Library; Cumulative Index to Nursing and Allied Health Literature (CINAHL); Institute for Scientific Information (ISI) Web of Science; Latin American and Caribbean Health Sciences Literature (LILACS); Spanish Health Sciences Bibliographic Index (IBECS). The search was carried out from the earliest date possible until July 2007.The medical subject heading terms used were ‘quality of life’, ‘nutritional status’ and ‘questionnaires’. The articles had to contain at least one questionnaire that evaluated quality of life. Twenty-eight documents fulfilling the inclusion criteria were accepted, although none of them used a specific questionnaire to evaluate HRQoL related to nutritional status. However, some of them used a combination of generic questionnaires with the intention of evaluating the same. Only three studies selectively addressed the relationship between nutritional status and quality of life, this evaluation being performed not by means of specific questionnaires but by statistical analysis of data obtained via validated questionnaires.

Evaluation of the health-related quality of life in elderly patients according to the type of hip fracture: femoral neck or trochanteric

OBJECTIVE

To evaluate the effect the type of hip fracture (femoral neck or trochanteric) has on the Health-Related Quality of Life of elderly subjects.

METHODS

Forty-five patients with hip fractures (mean 74.30 +/- 7.12 years), 24 with a femoral neck fracture and 21 with a trochanteric fracture, completed the 36-item Short Form Health Survey (SF-36) at baseline and four months after fracture. The Health-Related Quality of Life scores were compared according to fracture type, undisplaced and displaced femoral neck fractures, and stable and unstable trochanteric fractures.

RESULTS

Compared to baseline, all patients scored lower in the physical functioning, role limitation-physical, bodily pain and vitality categories four months after the fracture had occurred. The SF-36 scores for all the scales did not differ significantly between patients with femoral neck versus trochanteric fractures, or between patients with displaced versus undisplaced femoral neck fractures and stable versus unstable trochanteric fractures.

CONCLUSIONS

The mental and physical quality of life of elderly patients with a hip fracture is severely impaired one month after fracture, with partial recovery by the end of the fourth month. The negative impact on the Health-Related Quality of Life did not differ significantly according to fracture type.

Patient satisfaction, pain, and quality of life 4 months after displaced femoral neck fractures: a comparison of 663 fractures treated with internal fixation and 906 with bipolar hemiarthroplasty reported to the Norwegian Hip Fracture Register

BACKGROUND

Primary arthroplasty and internal fixation are the two main options for treatment of displaced femoral neck fractures. Despite the fact that there have been several randomized studies, the optimal treatment in the elderly is still controversial. In the present study, based on data from the Norwegian Hip Fracture Register, we compared satisfaction, pain, and quality of life 4 months after surgery in patients over 70 years of age with a displaced femoral neck fracture operated with internal fixation or with a bipolar hemiarthroplasty.

PATIENTS AND METHODS

Data on 1,569 fractures in patients over 70 years of age operated with internal fixation (n = 663) or hemiarthroplasty (n = 906) were registered in the hip fracture register. The register also included data on patient satisfaction, pain, and quality of life (EQ-5D) assessed 4 months after surgery using VAS scales and EQ-5D health questionnaires.

RESULTS

Patients operated with hemiarthroplasty had less pain (VAS 27 vs. 41), were more satisfied with the result of the operation (VAS 33 vs. 48), and had better EQ-5D index score 4 months postoperatively (0.51 vs. 0.42) than patients who were operated with internal fixation.

INTERPRETATION

Our findings suggest that elderly patients with displaced femoral neck fracture should be treated with arthroplasty.

A life-breaking event: early experiences of the consequences of a hip fracture for elderly people

Objective: To explore and describe the consequences of an acute hip fracture as experienced by home-dwelling elderly people shortly after discharge from hospital.

Design: Semi-structured interviews using the phenomenographic method.

Subjects and setting: Eighteen subjects were interviewed in their own homes one month after discharge.

Results: The interviewees described experiences of changes in their relation to the body, themselves, to others and to their whole life situation. These experiences were described as being limited in movement, having lost confidence in the body, becoming humble and grateful, respecting oneself and one's own needs, becoming more dependent on others, gaining more human contact and being treated in a friendly way by others, being secluded and trapped at home, feeling old, closer to death and having lost their zest for life, and taking one day at a time and being uncertain about the future.

Conclusion: Experienced consequences of a hip fracture were multidimensional and involved dramatic changes in the interviewees' life situation, including existential thoughts and reappraisal of the years of life that remained. The results indicate that the fracture seemed not only to break the bone but also to cause social and existential cracks, as experienced in the early phase after the injury.

A randomised controlled trial comparing bipolar hemiarthroplasty with total hip replacement for displaced intracapsular fractures of the femoral neck in elderly patients

The best treatment for the active and lucid elderly patient with a displaced intracapsular fracture of the femoral neck is still controversial. Randomised controlled trials have shown that a primary total hip replacement is superior to internal fixation as regards the need for secondary surgery, hip function and health-related quality of life. Despite good results achieved with total hip replacement in this group, most orthopaedic surgeons still advocate hemiarthroplasty for this injury. We studied 120 patients with a mean age of 81 years (70 to 90) with an acute displaced intracapsular fracture of the femoral neck. They were randomly allocated to be treated with either a bipolar hemiarthroplasty or total hip replacement. Outcome measurements included peri-operative data, general and hip-specific complications, hip function and health-related quality of life. The patients were reviewed at four and 12 months.

The duration of surgery was longer in the total hip replacement group (102 minutes (70 to 151)) versus 78 minutes (43 to 131) (p < 0.001), and the intra-operative blood loss was increased 460 ml (100 to 1100) versus 320 ml (50 to 850) (p < 0.001), but there were no differences between the groups regarding any complications or mortality. There were no dislocations in either group. Hip function measured by the Harris hip score was significantly better in the total hip replacement group at both follow-up periods (p = 0.011 and p < 0.001, respectively). The health-related quality of life measure was in favour of the total hip replacement group but did not reach statistical significance (p = 0.818 at four months and p = 0.636 at 12 months).

These results indicate that a total hip replacement provides better function than a bipolar hemiarthroplasty as soon as one year post-operatively, without increasing the complication rate. We recommend total hip replacement as the primary treatment for this group of patients.

Guidelines for the Conduction of Follow-up Studies Measuring Injury-Related Disability

BACKGROUND

Scientific knowledge on functional outcome after injury is limited. During the past decade, a variety of measures have been used at various moments in different study populations. Guidelines are needed to increase comparability between studies.

METHODS

A working group of the European Consumer Safety Association conducted a literature review of empirical studies into injury-related disability (1995-2005). We included injury from all levels of severity and selected studies using generic health status measures with both short-term and long-term follow up. The results were used as input for a consensus procedure toward the development of guidelines for defining the study populations, selecting the health status measures, selecting the timings of the assessments, and data collection procedures.

RESULTS

The group reached consensus on a common core of health status measures and assessment moments. The group advises to use a combination of EuroQol-5D and Health Utilities Mark III in all studies on injury-related disability. This combination covers all relevant health domains, is applicable in all kinds of injury populations and in widely different age ranges, provides a link with utility scores, and has several practical advantages (e.g., brevity, availability in different languages). For specific types of injury, the common core may be supplemented by injury-specific measures. The group advises a common core of assessments at 1, 2, 4, and 12 months after injury.

CONCLUSIONS

Our guidelines should be tested and may lead to improved and more consistent epidemiologic data on the incidence, severity, and duration of injury-related disability.

Internal fixation versus arthroplasty for intracapsular proximal femoral fractures in adults

BACKGROUND

Displaced intracapsular fractures may be treated by either reduction and internal fixation, which preserves the femoral head, or by replacement of the femoral head with an arthroplasty.

OBJECTIVES

To review all randomised controlled trials that have compared internal fixation with arthroplasty for intracapsular femoral fractures in adults.

SEARCH STRATEGY

We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (December 2005), the Cochrane Central Register of Controlled Trials (The Cochrane Library 2005, Issue 4), MEDLINE, EMBASE, the UK National Research Register, several orthopaedic journals, conference proceedings and reference lists of articles. We contacted trialists where possible.

SELECTION CRITERIA

All randomised and quasi-randomised controlled trials comparing internal fixation with arthroplasty for intracapsular hip fractures in adults.

DATA COLLECTION AND ANALYSIS

Trial quality was assessed by use of a 10 item scale. At least two review authors independently assessed trial quality and extracted data. Additional information was sought from trialists. After grouping into three broad categories, comparable groups of trials were subgrouped and where appropriate, data were pooled using the fixed-effect model.

MAIN RESULTS

Seventeen trials involving 2694 participants were included. Length of surgery, operative blood loss, need for blood transfusion and risk of deep wound infection were significantly less for internal fixation compared with arthroplasty. Arthroplasty had a significantly lower re-operation rate in comparison with fixation. No definite differences for hospital stay, mortality, or regain of same residential state were found. Limited information from some studies suggested pain was less and function was better for a cemented arthroplasty in comparison to fixation.

AUTHORS' CONCLUSIONS

Internal fixation is associated with less initial operative trauma but has an increased risk of re-operation on the hip. Definite conclusions cannot be made for differences in pain and residual disability between the two groups. Future studies should concentrate on better reporting of final outcome measures and there is still a need for studies to define which patient groups are better served by the different treatment methods.

Nutritional supplementation for hip fracture aftercare in older people

BACKGROUND

Older people with hip fractures are often malnourished at the time of fracture, and have poor food intake subsequently.

OBJECTIVES

To review the effects of nutritional interventions in older people recovering from hip fracture.

SEARCH STRATEGY

We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (December 2005), the Cochrane Central Register of Controlled Trials (The Cochrane Library 2006, Issue 1), MEDLINE, six other databases and reference lists. We contacted investigators and handsearched journals.

SELECTION CRITERIA

Randomised and quasi-randomised controlled trials of nutritional interventions for people aged over 65 years with hip fracture.

DATA COLLECTION AND ANALYSIS

Both authors independently selected trials, extracted data and assessed trial quality. We sought additional information from trialists, and pooled data for primary outcomes.

MAIN RESULTS

Twenty-one randomised trials involving 1727 participants were included. Overall trial quality was poor, specifically regarding allocation concealment, assessor blinding and intention-to-treat analysis, and limited availability of outcome data. Eight trials evaluated oral multinutrient feeds: providing non-protein energy, protein, some vitamins and minerals. Oral feeds had no statistically significant effect on mortality (15/161 versus 17/176; relative risk (RR) 0.89, 95% confidence interval (CI) 0.47 to 1.68) but may reduce 'unfavourable outcome' (combined outcome of mortality and survivors with medical complications) (14/66 versus 26/73; RR 0.52, 95% CI 0.32 to 0.84). Four trials examining nasogastric multinutrient feeding showed no evidence of an effect on mortality (RR 0.99, 95% CI 0.50 to 1.97) but the studies were heterogeneous regarding case mix. Nasogastric feeding was poorly tolerated. There was insufficient information for other outcomes. Increasing protein intake in an oral feed was tested in four trials. There was no evidence for an effect on mortality (RR 1.42, 95% CI 0.85 to 2.37). Protein supplementation may have reduced the number of long term medical complications. Two trials, testing intravenous vitamin B1 and other water soluble vitamins, or 1-alpha-hydroxycholecalciferol (an active form of vitamin D) respectively, produced no evidence of effect for either supplement. One trial, evaluating dietetic assistants to help with feeding, showed a trend for a reduction in mortality (RR 0.57, 99% CI 0.29 to 1.11).

AUTHORS' CONCLUSIONS

Some evidence exists for the effectiveness of oral protein and energy feeds, but overall the evidence for the effectiveness of nutritional supplementation remains weak. Adequately sized trials are required which overcome the methodological defects of the reviewed studies. In particular, the role of dietetic assistants requires further evaluation.

Responsiveness of the EuroQol (EQ-5D) and the Nottingham Health Profile (NHP) in elderly patients with femoral neck fractures

INTRODUCTION

The objective of this study was to evaluate the internal and external responsiveness of the EuroQol (EQ-5D) and the Nottingham Health Profile (NHP) and to evaluate the overlap of change scores from the two instruments.

METHODS

Sixty patients with femoral neck fractures treated with internal fixation at a university hospital participated. Internal responsiveness was assessed using a paired t-test and the standardised response mean (SRM) for patients with displaced fractures hypothesised to deteriorate between baseline and the 6-month follow-up. In the analyses of external responsiveness, receiver operator characteristics (ROC) and logistic regression were employed to assess the correspondence between the chosen external criterion (EC) defining fracture displacement, i.e. displaced vs. undisplaced fractures, and the change scores from the EQ-5D and the NHP. The overlap in change scores for the overall scores and comparable subdimensions of the two instruments was evaluated by correlational analyses.

RESULTS

The SRM were large and the change in HRQoL over time was statistically significant for both instruments in patients with displaced fractures. A correspondence was found between the EC and change scores for both questionnaires. The correlation coefficients between the change scores for the overall scores and comparable subdimensions of the two instruments ranged from relatively small to moderate.

CONCLUSIONS

The results yielded support for the internal and external responsiveness of the EQ-5D and the NHP and indicated an advantage for the EQ-5D. The empirical overlap between change scores from the two instruments was limited.

Displaced femoral neck fracture: comparison of primary total hip replacement with secondary replacement after failed internal fixation: a 2-year follow-up of 84 patients

INTRODUCTION

Recent randomized controlled trials have shown that for the active and lucid elderly patient with a displaced femoral neck fracture, a primary total hip replacement (THR) is superior to internal fixation (IF) regarding the need for secondary surgery, hip function and health-related quality of life (HRQoL). Despite the high failure rate for IF, the method is still recommended for this patient cohort by some authors. One argument is that if IF fails, there is always the possibility of performing a secondary salvage THR. The main aim of our study was to determine whether a primary THR, as compared to a secondary THR after failed IF, gives a better outcome after 2 years.

METHODS

We compared outcome for 43 patients with a primary THR to the outcome for 41 patients who were treated with a secondary THR after failed IF. All patients (mean age 80 years) were lucid and had a displaced femoral neck fracture. Hip function (Charnley score) and health-related quality of life (HRQoL, EQ5D) were assessed 2 years after the THR procedure.

RESULTS

Hip function was better in the primary THR group: the mean Charnley score was 15/18 as compared to 13/18 in the secondary THR group (p < 0.001). The patients with failed IF who later underwent a secondary THR experienced a more pronounced decrease in HRQoL (EQ-5D index score) during the first year of treatment compared to patients in the primary THR group, with a difference of 0.25 in the EQ-5D index score at the 4-month follow-up (p = 0.02).

INTERPRETATION

We found that a secondary THR after failed IF results in inferior hip function compared to a primary THR for a displaced femoral neck fracture in the active and lucid elderly patient. Moreover, the patients with failed IF had to undergo at least one re-operation and experienced a significant reduction in HRQoL before the salvage THR.
