Distal radius malunion: outcomes following an ulnar shortening osteotomy.

PURPOSE: Positive ulnar variance following a distal radius malunion can lead to ulnar-sided wrist pain, loss of grip strength, and distal radioulnar joint impingement. The primary aim of this study is to describe upper limb-specific functional outcomes following ulnar shortening osteotomy (USO) for ulnar-sided wrist pain associated with malunion of the distal radius. METHODS: We retrospectively identified 40 adult patients from a single centre over a 9-year period that had undergone an USO for symptomatic malunion of the distal radius. The primary outcome was the patient-rated wrist evaluation (PRWE). Secondary outcomes were the QuickDASH, EQ-5D-5L, complications, and net promoter score (NPS). RESULTS: Outcomes were available for 37 patients (93%). The mean age was 56 years and 25 patients were female (68%). At a mean follow-up of 6 years (range 1-10 years) the median PRWE was 11 (IQR 0-29.5), the median QuickDASH 6.8 (IQR 0-29.5), and the median EQ-5D-5L index was 0.88 (IQR 0.71-1). The NPS was 73. Complications occurred in nine patients (24%) and included non-union (n = 4), early loss of fixation requiring revision surgery (n = 1), superficial wound infection (n = 2), neurological injury (n = 1), and further surgery for symptomatic hardware removal (n = 1). CONCLUSIONS: For patients with a symptomatic distal radius malunion where the predominant deformity is ulnar positive variance, this study has demonstrated that despite 1 in 4 patients experiencing a complication, USO can result in excellent patient reported outcomes with high levels of satisfaction. LEVEL OF EVIDENCE: III (Cohort Study).

Diagnosis of Suspected Scaphoid Fractures.

¼: Suspected scaphoid fractures are a diagnostic and therapeutic challenge despite the advances in knowledge regarding these injuries and imaging techniques. The risks and restrictions of routine immobilization as well as the restriction of activities in a young and active population must be weighed against the risks of nonunion that are associated with a missed fracture. ¼: The prevalence of true fractures among suspected fractures is low. This greatly reduces the statistical probability that a positive diagnostic test will correspond with a true fracture, reducing the positive predictive value of an investigation. ¼: There is no consensus reference standard for a true fracture; therefore, alternative statistical methods for calculating sensitivity, specificity, and positive and negative predictive values are required. ¼: Clinical prediction rules that incorporate a set of demographic and clinical factors may allow stratification of secondary imaging, which, in turn, could increase the pretest probability of a scaphoid fracture and improve the diagnostic performance of the sophisticated radiographic investigations that are available. ¼: Machine-learning-derived probability calculators may augment risk stratification and can improve through retraining, although these theoretical benefits need further prospective evaluation. ¼: Convolutional neural networks (CNNs) are a form of artificial intelligence that have demonstrated great promise in the recognition of scaphoid fractures on radiographs. However, in the more challenging diagnostic scenario of a suspected or so-called "clinical" scaphoid fracture, CNNs have not yet proven superior to a diagnosis that has been made by an experienced surgeon.

Tibial shaft fractures - to monitor or not? a multi-centre 2 year comparative study assessing the diagnosis of compartment syndrome in patients with tibial diaphyseal fractures.

AIMS: The aim of this study was to compare the outcome in patients who did and did not undergo continuous compartment pressure monitoring (CCPM) following a tibial diaphyseal fracture. PATIENTS AND METHODS: We performed a retrospective cohort study of 287 patients with an acute tibial diaphyseal fractures who presented to three centres over a two-year period. Demographic data, diagnosis, management, wound closure, complications, and subsequent surgeries were recorded. The primary outcome measure was the rate of short-term complications. Secondary outcomes were time to fasciotomy and split-skin grafting rates. RESULTS: Of the 287 patients in the study cohort, 171 patients underwent CCPM (monitored group; MG) and 116 did not (non-monitored group; NMG). There were 21 patients who developed ACS and underwent fasciotomy, with comparable rates in both groups (n=13 in the MG vs n=8 in NMG; p=0.82). There was no difference in the rate of complications between groups (all p>0.05). The mean time from admission to fasciotomy was 22.1hrs, with a mean time of 19.8hrs in the MG and 25.8hrs in the NMG (mean difference, 6hrs; p=0.301). One patient in the NMG required a below-knee amputation. There was a trend towards a reduced requirement for split-skin grafting post decompression in the MG (15% vs 50%; p=0.14). CONCLUSION: This study found no difference in the short-term complication rates in those patients that underwent CCPM and those that did not following a fracture of the tibial diaphysis. CCPM does appear to be safe with no increase in the rate of fasciotomies performed. There was a trend towards a reduced time to fasciotomy and a reduced rate of split skin grafting for wound closure with CCPM. LEVEL OF EVIDENCE: Level III (Diagnostic: Retrospective cohort study).

The rate and associated risk factors for acute carpal tunnel syndrome complicating a fracture of the distal radius.

BACKGROUND: Acute carpal tunnel syndrome (ACTS) is a known complication of distal radius fractures. This study aimed to document the demographics, range of presenting symptoms and risk factors of patients who develop ACTS following a fracture of the distal radius. METHODS: A retrospective review of 1189 patients with an acute distal radius fracture treated in the study centre over a one-year period were identified. Demographic and clinical variables were collected and compared between controls (did not develop ACTS) and those patients who did develop ACTS to identify factors associated with developing ACS. RESULTS: There were 51 (4.3%) distal radius fractures complicated by ACTS. The mean age of patients who developed ACTS was 56 years (range, 16-89) and 73% were female. The median time of onset post-injury was one week (range, 1-12). There was no association between patient background and comorbidities with the development of ACTS. AO-OTA Type C fractures had significantly increased rates of developing ACTS. CONCLUSION: Four percent of distal radius fractures were complicated by ACTS. There was no association between patient background and comorbidities with the development of ACTS. AO-OTA type C complete articular fractures had a significantly higher rate of ACTS. A suggested treatment algorithm for patients presenting with ACTS has been presented. LEVEL OF EVIDENCE: III.

Patient-reported outcomes after corrective osteotomy for a symptomatic malunion of the distal radius.

AIMS: The primary aim of this study was to describe patient satisfaction and health-related quality of life (HRQoL) following corrective osteotomy for a symptomatic malunion of the distal radius. METHODS: We retrospectively identified 122 adult patients from a single centre over an eight-year period who had undergone corrective osteotomy for a symptomatic malunion of the distal radius. The primary long-term outcome was the Patient-Rated Wrist Evaluation (PRWE) score. Secondary outcomes included the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) score, the EQ-5D-5L score, complications, and the Net Promoter Score (NPS). Multivariate regression analysis was used to determine factors associated with the PRWE score. RESULTS: Long-term outcomes were available for 89 patients (72%). The mean age was 57 years (SD 15) and 68 were female (76%). The median time from injury to corrective osteotomy was nine months (interquartile range (IQR) 6 to 13). At a mean follow-up of six years (1 to 11) the median PRWE score was 22 (IQR 7 to 40), the median QuickDASH score was 11.4 (IQR 2.3 to 31.8), and the median EQ-5D-5L score was 0.84 (IQR 0.69 to 1). The NPS was 69. Multivariate regression analysis showed that the presence of an associated ulnar styloid fracture was the only significant independent factor associated with a worse PRWE score when adjusting for confounding variables (p = 0.004). CONCLUSION: We found that corrective osteotomy for malunion of the distal radius can result in good functional outcomes and high levels of patient satisfaction. However, the presence of an ulnar styloid fracture may adversely affect function. Level of Evidence: III (cohort study). Cite this article: Bone Joint J 2020;102-B(11):1542-1548.

High Risk of Further Surgery After Radial Head Replacement for Unstable Fractures: Longer-term Outcomes at a Minimum Follow-up of 8 Years.

BACKGROUND: The evidence for treating acute, unreconstructable radial head fractures in unstable elbows with radial head replacement predominantly consists of short- to mid-term follow-up studies with a heterogenous mix of implants and operative techniques. Data on longer-term patient-reported outcomes after radial head replacement is lacking. QUESTIONS/PURPOSES: (1) What proportion of patients undergo revision or implant removal after radial head replacement? (2) At a minimum of 8 years follow-up, what are the patient-reported outcomes (QuickDASH, Oxford Elbow Score, and EuroQol-5D)? (3) What factors are associated with a superior long-term patient-reported outcome, according to the QuickDASH? METHODS: Between September 1994 and September 2010, we surgically treated 157 patients for acute radial head fractures. We excluded patients where the radial head was excised (n = 21), internally fixed (n = 15), or replaced as a secondary procedure after failed internal fixation (n = 2). A total of 119 patients who underwent radial head replacement surgery for an acute unreconstructable fracture were included, with a mean age of 50 years (range 15 to 93 ± 19 years), and 53% of patients (63) were women. All but two implants were uncemented, loose-fitting, monopolar prostheses, of which 86% (102) were metallic and 14% (17) were silastic. Implants were only cemented if they appeared unstable within the proximal radius. Silastic implants were used in the earlier series and replaced by metallic implants starting in 2000. We reviewed electronic records to document postoperative complications and prosthesis revision and removal. A member of the local research team (THC, CDC) who was not previously involved in patient care contacted patients to confirm complications, reoperations and to obtain long-term patient-reported outcomes scores. Nineteen patients had died at the point of outcome score collection. Of the remaining 100 patients, 80 were contacted (67% of total cohort), at a median of 11 years (range 8 to 24 years) after injury. The primary outcome measure was the QuickDASH score. RESULTS: Of 119 patients, 25% (30) underwent reoperation, with three patients undergoing revision and 27 patients undergoing prosthesis removal at a median of 7 months (range 0 to 125 months). Twenty-one of 30 procedures (70%) occurred within 1 year after implantation. Kaplan-Meier survivorship analysis demonstrated a cumulative implant survival rate of 71%. In the 80 patients contacted, the mean QuickDASH score was 13 ± 14, the mean Oxford Elbow Score was 43 ± 6, and the median EuroQol-5D score was 0.8 (-0.3 to 1.0). After controlling for covariates, we found that prothesis revision or removal (p = 0.466) and prosthesis type (p = 0.553) were not associated with patient-reported outcome, according to the QuickDASH. CONCLUSIONS: The management of acute unreconstructable fractures of the radial head in unstable elbow injuries with radial head replacement has a high risk of reoperation. Patients must be counselled regarding this risk of secondary intervention, of which the peak risk appears to be within 1 year after implantation. Despite this, patients report low disability according to the QuickDASH at a minimum follow-up of 8 years. LEVEL OF EVIDENCE: Level IV, therapeutic study.

Effect of Alendronic Acid on Fracture Healing: A Multicenter Randomized Placebo-Controlled Trial.

There is a concern that bisphosphonates may impair fracture healing because of their inhibitory effects on bone turnover. Here we evaluated the effects of early bisphosphonate therapy on fracture healing and functional outcome following a fracture of the distal radius. The fracture and bisphosphonates (FAB) trial was a double-blind, randomized, placebo-controlled trial involving 15 trauma centers in the United Kingdom. We enrolled 421 bisphosphonate-naive patients aged ≥50 years with a radiographically confirmed fracture of the distal radius and randomized them in a 1:1 ratio to receive alendronic acid 70 mg once weekly (n = 215) or placebo (n = 206) within 14 days of the fracture. The primary outcome measure was the proportion of fractures that had radiologically united at 4 weeks as assessed by an observer, blinded to treatment allocation. Secondary outcomes included the Disabilities of the Arm Shoulder and Hand (DASH) questionnaire, range of wrist movement and grip strength, pain and analgesia requirements, and the rate of malunion. The mean ± SD age of participants was 63 ± 8.5 years and 362 (86%) were female. At 4 weeks, 48 of 202 (23.8%) fractures had united in the alendronic acid group compared with 52 of 187 (27.8%) in the placebo group (observed absolute proportion difference 4.0%; 95% CI, -4.7% to 12.8%; p = 0.36). The absolute proportion difference between groups based on imputed data was 4.5% (95% CI, -4.7% to 13.8%; p = 0.30). There was no significant difference in the proportion of fractures that had united at any other time point and no differences in the DASH score, pain at the fracture site, grip strength, or any other clinical outcome. We conclude that among patients aged 50 years and above with a distal radius fracture, early administration of alendronic acid does not adversely affect fracture union or clinical outcome. These findings suggest bisphosphonate therapy can be safely commenced early after fracture if clinically indicated. © 2019 American Society for Bone and Mineral Research.

Fractures in older adults. A view of the future?

INTRODUCTION: It is accepted that the incidence of fractures in patients aged ≥ 65 years is increasing but little is known about which fractures are becoming more common in this group of patients. Virtually all research has concentrated on the classic fragility fractures of the proximal femur, proximal humerus, pelvis, spine and distal radius but it is likely that other fractures are becoming more common. METHODS: We have examined two prospectively collected databases 10 years apart to see which fractures are becoming more common in ≥ 65 year old patients. We compared the fractures to look for epidemiological differences over the 10-year period and we compared the epidemiology of the fractures that had increased in incidence with equivalent fractures in the < 65 year old population. RESULTS: Analysis shows that in older female patients fractures of the clavicle, finger phalanges, ankle and metatarsus are increasing in incidence. In males there is an increasing incidence of fractures of the proximal humerus, distal humerus, metacarpus, pelvis, femoral diaphysis, distal tibia and ankle. In females the basic epidemiology of fractures in the ≥ 65 year old population was very similar to the fractures seen in younger females and we believe that the increasing incidence of fractures in the future will mainly be low velocity fractures following falls. In older males however, it is apparent that there is a much wider variation in the causes of fracture. DISCUSSION: We believe that the changes in fracture epidemiology in older patients relate to improved health and longevity and analysis of our population during the study period shows significant social changes which are associated with increased longevity and improved health. It is probable that fractures in older patients will continue to increase in incidence and that other fractures that are now commonly seen in middle-aged patients will be seen in older patients. Surgeons will have to treat more complex fractures in older males than in older females and it is likely that there will be a higher incidence of open and multiple fractures. Appropriate management techniques will need to be established.

Tibial Fracture Nonunion and Time to Healing After Reamed Intramedullary Nailing: Risk Factors Based on a Single-Center Review of 1003 Patients.

OBJECTIVE: To determine factors associated with nonunion of adult tibial fractures. DESIGN: Retrospective review with data collection for logistic regression and survival analysis. SETTING: Scottish Level I trauma center, 1985-2007. PATIENTS: During this period, 1590 adult tibial fractures were treated by reamed nailing and 1003 fractures met all inclusion criteria for the chosen analysis. INTERVENTION: Reamed intramedullary nailing. MAIN OUTCOME MEASURES: Record of nonunion diagnosis and final union time with characteristics, including age, gender, closed or open injury, OTA/AO classification, Gustilo classification, fasciotomy, infection, polytrauma, smoking, and injury severity score. RESULTS: The overall nonunion rate was 12%, and median time to healing was 18 weeks. Age significantly influenced nonunion, with middle-aged patients at highest risk. Both fracture type (closed/open) and morphology (OTA/AO classification) significantly influenced nonunion risk and time to union. Among closed injuries, the highest nonunion rate was for OTA/AO type B fractures (15%). Among open injuries, the highest nonunion rate was for OTA/AO type C (61%). Both compartment syndrome and smoking did not significantly influence nonunion risk but did significantly extend time to union. CONCLUSIONS: Injury characteristics including fracture morphology and severity of soft tissue injury were strong predictors of compromised fracture healing. Age also influenced nonunion risk in an unexpected way, with highest rates in the middle decades of adulthood. Future studies should consider the possibility of similar age-related effects and clinical studies should seek to identify explanations for why this may arise, including both physiological and socio-behavioral factors.

Plate Versus Tension-Band Wire Fixation for Olecranon Fractures: A Prospective Randomized Trial.

BACKGROUND: The aim of this single-center, single-blinded, prospective randomized trial was to compare the outcomes of tension-band wire (TBW) and plate fixation for simple isolated, displaced fractures of the olecranon. METHODS: We performed a prospective randomized trial involving 67 patients who were ≥16 to <75 years of age and had an acute isolated, displaced fracture of the olecranon. Patients were randomized to either TBW (n = 34) or plate fixation (n = 33) and were evaluated at 6 weeks, 3 months, 6 months, and 1 year following surgery. The primary outcome measure was the Disabilities of the Arm, Shoulder and Hand (DASH) score at 1 year. RESULTS: The baseline demographic and fracture characteristics of the 2 groups were comparable, except for age, which was lower in the TBW group. The 1-year follow-up rate was 85% (n = 57), with 84% (n = 56) completing the DASH. There was a significant improvement in the DASH score over the 1-year period following surgery (p < 0.001). At 1 year, the DASH score for the TBW group (12.8) did not differ significantly from that of the plate group (8.5) (p = 0.315). The groups also did not differ significantly in terms of range of motion, the Broberg and Morrey score, the Mayo Elbow Score, or the DASH at all assessment points over the 1 year (all p ≥ 0.05). Complication rates were significantly higher in the TBW group (63% compared with 38%; p = 0.042), predominantly because of a significantly higher rate of metalwork removal in symptomatic patients (50.0% compared with 22%; p = 0.021). Four infections occurred, all in the plate group (0% versus 13%; p = 0.114), as did 3 revision surgeries (0% versus 9.4%; p = 0.238). CONCLUSIONS: Among active patients with a simple isolated, displaced fracture of the olecranon, no difference was found between TBW and plate fixation in the patient-reported outcome at 1 year following surgery. The complication rate was higher following TBW fixation and was due to a higher rate of implant removal in symptomatic patients. However, the more serious complications of infection and the need for revision surgery occurred exclusively following plate fixation in this trial. LEVEL OF EVIDENCE: Therapeutic Level I.

Open Finger Fractures: Incidence, Patterns of Injury and the Influence of Social Deprivation.

BACKGROUND: This study investigates the patterns and epidemiology of open finger fractures. There is little good data about these injuries. METHODS: Data were collected prospectively in a single trauma unit serving a well-defined population. RESULTS: Over a 15 year period 1090 open finger fractures were treated in 1014 patients. These made up the vast majority of open fractures treated in the trauma unit during this period. The incidence of open finger fractures was 14.0 per 100,000 patients per year. Deprivation did not influence the incidence of open finger fractures but did affect treatment choices for women. Most open finger fractures resulted from crush injuries or falls and required only simple operative treatments: debridement, lavage and early mobilization. CONCLUSIONS: Open finger fractures formed the majority of the workload of open fractures at our trauma centre but usually required simple treatments only. Social deprivation was not shown to influence the patterns or epidemiology of these injuries but did affect treatment choices for women.

Global Forum: Fractures in the Elderly.

Fractures in the elderly are increasing in incidence and becoming a major health issue in many countries. With an increasing number of the elderly living to an older age, the problems associated with fractures will continue to increase. We describe the epidemiology of fractures in the elderly and identify six fracture patterns in the population of patients who are sixty-five years of age or older. We also analyzed multiple fractures and open fractures in the elderly and we show that both increase in incidence with older age. The incidence of open fractures in elderly women is equivalent to that in young men. Many factors, including patient socioeconomic deprivation, increase the incidence of fractures in the elderly. More than 90% of fractures follow low-energy falls and the mortality is considerable. Mortality increases with older age and medical comorbidities, but there is also evidence that it relates to premature discharge from the hospital.

Acute Median Neuropathy and Carpal Tunnel Release in Perilunate Injuries Can We Predict Who Gets a Median Neuropathy?

UNLABELLED: This study addressed the following null hypotheses: 1) There are no demographic differences between patients with perilunate dislocation (PLD) or fracture-dislocation (PLFD); 2) There are no factors associated with the development of median nerve symptoms in the setting of a PLD or PLFD; and 3) There are no factors associated with carpal tunnel release. Using a retrospective search of a prospective trauma database, we identified all patients who had sustained a radiologically confirmed PLD or PLFD over a 10-year period at two trauma centers. From the medical records we identified median nerve symptoms and carpal tunnel release in addition to demographic and injury characteristics. Among the 71 patients treated for PLD or PLFD, acute median neuropathy was diagnosed in 33 patients (47 %). The only significant difference between PLD and PLFD was a younger age with PLFD. No demographic or injury factors were associated with symptoms of median neuropathy. Carpal tunnel release surgery during the initial operative management was related to the presence of median nerve symptoms and the trauma center. We report a high incidence of acute median neuropathy accompanying perilunate injuries. As there are no demographic or injury factors associated with symptoms of median neuropathy; all patients with PLD/PLFD merit equally high vigilance for acute median neuropathy. LEVEL OF EVIDENCE: Level III, prognostic study.

The role of primary plastic surgery in the management of open fractures.

A study was undertaken to determine the requirement for primary plastic surgery in the treatment of open fractures. We reviewed 3297 consecutive open fractures in a 22-year period in a defined population. Analysis showed that 12.6% of patients required primary plastic surgery with 5.6% being treated with split skin grafting and 7.2% with a flap. Only 3.5% of open upper limb fractures required primary plastic surgery compared to 27.9% of open lower limb fractures. The fractures that required most primary plastic surgery were those of the femoral diaphysis and all fractures between the proximal tibia and the midfoot. The incidence of open fractures that require primary plastic surgery was 28/10(6)/year. The incidence in open upper and lower limb fractures was 5.3/10(6)/year and 22.7/10(6)/year respectively. Using these figures it is possible to estimate the numbers of open fractures that will require primary plastic surgery each year in the United Kingdom.

Predictors of Compartment Syndrome After Tibial Fracture.

OBJECTIVES: The aim of our study was to identify the risk factors associated with the development of acute compartment syndrome (ACS) after a fracture of the tibia. DESIGN: Retrospective cohort study. SETTING: Orthopaedic trauma unit, university teaching hospital. PATIENTS: From our trauma database, we identified all patients who sustained an acute tibial diaphyseal fracture over a 13-year period. A retrospective analysis of 1407 patients was performed to record and analyze the OTA fracture classification, open fracture grade according to Gustilo, soft tissue injury classification according to Tscherne, treatment, development of ACS, and other patient demographics including smoking, occupation, and socioeconomic deprivation. MAIN OUTCOME MEASURE: A diagnosis of ACS was made using clinical signs, compartment pressure monitoring, or a combination of the 2. RESULTS: One thousand three hundred eighty-eight patients were included with a mean age of 39 (12-98) years, and 957 (69%) were male. One hundred sixty patients (11.5%) were diagnosed with ACS. On initial analysis, age, male gender, blue-collar occupation, sporting injury, fracture classification, and treatment with intramedullary nails were predictive of ACS (all P < 0.05). Age was the strongest predictor of developing ACS (P < 0.001), with the highest prevalence between 12-19 years and 20-29 years. Occupation (P = 0.01) and implant type (P = 0.004) were the only factors that remained significant after adjusting for age. On further subanalysis, implant type was not predictive when stratified by Tscherne class (P = 0.11). CONCLUSIONS: We have documented the risk factors for the development of ACS after an acute tibial diaphyseal fracture, with youth the strongest predictor. LEVEL OF EVIDENCE: Prognostic Level II.

Open ankle fractures: who gets them and why?

Open ankle fractures present a significant clinical challenge. The management and outcome of these injuries has been extensively reported, but there have been no reports of the epidemiology and how this has changed over time. We report 178 adult patients with open ankle fractures presenting to our unit over a twenty-three year period. The study centre is the only hospital receiving adult orthopaedic trauma in the region and has a defined population. The incidence of open ankle fractures was 1.5/10(5)/year, representing 1.5 % of all ankle fractures. The mean age was 55 years (range 16-96), with the highest incidence occurring in women over the age of 90. The most common mechanism was a simple fall with only 26 % of cases due to a motor vehicle collision (MVC). 82 % of cases were isolated injuries. Social deprivation had no significant influence on the incidence, but there was a difference in the mechanism with the majority of injuries in the most deprived quintile caused by MVCs and significantly fewer due to simple falls (p = 0.047). Over the twenty-three years, there was a significant increase in the mean age from 44 to 64 years (p = 0.03). The overall incidence remained constant over the two decades. In common with many traumatic injuries, open ankle fractures are increasingly low-energy insufficiency fractures affecting elderly patients, particularly older women. This has implications for service planning and training as well as the surgical intervention in these patients.

Predictors of poor clinical outcome following hip fracture in middle aged-patients.

The aim of this study was to investigate morbidity and mortality following hip fractures in middle aged patients. In addition, we aimed to identify risk factors which could be used to predict postoperative complications. All patients aged 40-55 who sustained a hip fracture in Lothian from 2007 to 2008 were identified from a prospective trauma database. The main outcomes were complications and 5-year mortality. Thirty hip fractures were included in the study. Complications occurred in nine (30%) cases. Deep infection was seen in three cases (10%). Mortality was 20% at 5 years, 26 times higher than for the general population. All surviving patients were contacted for risk factor analysis (24). Low energy fractures, alcohol excess, smoking and history of previous fractures were significantly associated with complications (p<0.05). Complications only occurred amongst low energy fractures. Risk factors were further analysed using the WHO FRAX algorithm. No patient with a FRAX score of less than 10 suffered a complication, whereas 50% of patients who had a FRAX score of more than 10 suffered a complication. The results of our study suggest that low energy hip fractures in middle age are due to underlying morbidity and are associated with a high incidence of postoperative complications and mortality. The FRAX score could be used as a simple method of identifying patients in this age group who are at risk of a poor outcome.

Long-term outcomes of isolated stable radial head fractures.

BACKGROUND: There is evidence to support primary nonoperative management of isolated stable fractures of the radial head, although minimal data exist regarding long-term outcomes. The aim of this study was to report subjective long-term outcomes of isolated stable fractures of the radial head and neck following primary nonoperative management. METHODS: From a prospective database of proximal radial fractures, we identified all skeletally mature patients who sustained an isolated stable Mason type-1 or type-2 fracture of the radial head or neck during an eighteen-month period. Inclusion criteria were a confirmed isolated stable fracture of the proximal aspect of the radius, primarily managed nonoperatively. The primary long-term outcome measure was the Disabilities of the Arm, Shoulder and Hand (DASH) score. RESULTS: The study cohort comprised 100 patients with a mean age of forty-six years (range, seventeen to seventy-nine years). A fall from a standing height accounted for 69% of all injuries. Thirty-five percent of the patients had one or more comorbidities. There were fifty-seven Mason type-1 fractures and forty-three Mason type-2 fractures. At a mean of ten years post injury (range, 8.8 to 10.2 years), the mean DASH score was 5.8 (range, 0 to 67.2) and the mean Oxford Elbow Score (OES) was 46 (range, 14 to 48). Fourteen (14%) of the patients reported stiffness and twenty-four (24%) reported some degree of pain. A worse DASH score was associated with older age (p = 0.002), one or more comorbidities (p = 0.008), increasing socioeconomic deprivation by Index of Multiple Deprivation quintile (p = 0.026), increasing amount of fracture displacement (p = 0.041), and involvement in compensation proceedings (p = 0.006). CONCLUSIONS: Long-term patient-reported outcomes were excellent following the nonoperative management of isolated stable fractures of the radial head or neck. We suggest that routine primary nonoperative management of these fractures provides a satisfactory outcome for the majority of patients, with few patients in our study requiring further intervention for persisting complaints.
