Risk factors associated with loss of position after closed reduction of distal radial fractures in children.

Background Closed reductions of distal radial fractures are among the most common orthopaedic operations but up to 39% of fractures lose position postoperatively. This study was carried out to determine the most significant risk factors for loss of position so that high-risk patients can be identified early and their management tailored accordingly. Methods We retrospectively reviewed 48 consecutive children who had redisplacement of their distal radial fractures after closed reduction and compared them with 48 matched controls. Fourteen risk factors were studied and analyzed with univariate and multivariate logistic regression analysis and receiver operating characteristics analysis. These risk factors included pre-reduction and post-reduction fracture characteristics as well as 4 previously described radiological indices of plaster quality. Results Significant independent clinical risk factors identified were the initial radial fracture displacement [odds ratio (OR) 1.03, P=0.001] and obliquity (OR 0.93, P=0.006), a completely displaced radial fracture (OR 5.21, P=0.003), an ipsilateral ulnar fracture (OR 3.56, P=0.003), residual radial displacement (OR 1.06, P=0.009), angulation (OR 1.16, P=0.011), and failure to achieve anatomical reduction (OR 0.18, P=0.004). Significant radiological indices included the Padding index (OR >100, P=0.004), Canterbury index (OR 99, P=0.014), and 3-point index (OR 19.29, P<0.001). Nonsignificant risk factors included the angulation of the initial radial fracture, a completely displaced ulnar fracture, plaster changes/splitting and the Cast index. The combined preoperative presence of a completely displaced radial fracture, an ipsilateral ulnar fracture and failure to achieve perfect reduction was found to be the best predictor of redisplacement (receiver operating characteristic area under the curve=0.82). This combination was found to be a better predictor of redisplacement than any of the radiological indices (receiver operating characteristic area under the curve ⩽0.74) and it is also a more practical risk factor for the operating surgeon to use. Conclusions The combination of a completely displaced distal radial fracture and an ipsilateral ulnar fracture, which then cannot be perfectly reduced, was the best predictor for redisplacement. We recommend that serious consideration be given to primary wire fixation in these patients. Level of Evidence III, prognostic.

Surgical management of Mason type III radial head fractures.

The evidence for optimal management of Mason type III fracture of radial head is unclear hence a systematic review of the published literature was performed in April 2012. This review includes 5 prospective studies (including 2 randomized trials), 4 retrospective studies and 9 case series. No study can be interpreted as level 1 evidence. Level 2 and 3 evidence provides some insight into the success of each modality through subjective and objective measurements of function and complication rates. Radial head replacement, open reduction internal fixation (ORIF) and radial head resection all provide satisfactory outcomes for patients in most cases. One treatment modality cannot be recommended over any other due to the small number of clinical trials and cases included in each study. Further randomized control trials are needed to evaluate the full benefits and shortcomings of each of the different surgical treatment modalities.

Review article: Paediatric supracondylar humeral fractures: Emergency assessment and management

Supracondylar humeral fractures in children are common presentations to the ED but might be challenging to both diagnose and assess clinically. The ED has a critical role in accurately assessing the child, the limbs neurovascular status and initiating treatment. A specific approach to the clinical assessment of such a child is required as failure to detect neurovascular compromise can delay appropriate treatment and result in serious consequences. Most children can be investigated with X‐ray radiograph alone with further treatment directed by severity of the fracture, commonly described using the Gartland classification. Our review article provides an overview of supracondylar humeral fractures and a suggested clinical approach to leave the emergency physician better equipped to assess and manage these fractures.

Complications associated with operative fixation of acute midshaft clavicle fractures

INTRODUCTION The aim of this study was to review the complication rate and profile associated with surgical fixation of acute midshaft clavicle fracture in a large cohort of patients treated in a level I trauma centre. PATIENTS AND METHODS We identified all patients who underwent surgical treatment of acute midshaft clavicle fracture between 2002 and 2010. The study group consisted of 138 fractures (134 patients) and included 107 men (78%) and 31 women (22%); the median age of 35 years (interquartile range (IQR) 24-45). The most common mechanism of injury was a road traffic accident (78%). Sixty percent (n=83) had an injury severity score of ≥15 indicating major trauma. The most common fracture type (75%) was simple or wedge comminuted (2B1) according to the Edinburgh classification. The median interval between the injury and operation was 3 days (IQR 1-6). Plate fixation was performed in 110 fractures (80%) and intramedullary fixation was performed in 28 fractures (20%). There were 85 men and 25 women in the plate fixation group with median age of 35 years (IQR 25-45) There were 22 men and six women in the intramedullary fixation group with median age of 31 years (IQR 24-42 years). Statistical analysis was performed using independent sample t test, Mann Whitney test, and Chi square test. Significant P-value was <0.05. RESULTS The overall incidence of complication was 14.5% (n=20). The overall nonunion rate was 6%. Postoperative wound infection occurred in 3.6% of cases. The incidence of complication associated with plate fixation was 10% (11 of 110 cases) compared to 32% associated with intramedullary fixation (nine of 28 cases; P=0.003). Thirty-five percent of complications were related to inadequate surgical technique and were potentially avoidable. Symptomatic hardware requiring removal occurred in 23% (n=31) of patients. Symptomatic metalware was more frequent after plate fixation compared to intramedullary fixation (26% vs 7%, P=0.03). CONCLUSIONS Intramedullary fixation of midshaft clavicle fracture is associated with a higher incidence of complications. Plate fixation is associated with a higher rate of symptomatic metalware requiring removal compared to intramedullary fixation. Approximately one in three complications may be avoided by attention to adequate surgical technique.

Sterile stockinette in orthopaedic surgery: a possible pathway for infection.

The prevention of infection in joint replacement surgery is important. Preparing and draping the patient is fundamental to maintaining sterility of the operative field. One method of draping for total knee replacement (TKR) surgery involves cleaning the operative leg with antiseptic wash then covering the un‐prepped foot with a sterile stockinette to sequester the foot from the sterile field. There are two main methods for applying this stockinette. This randomized, blinded control trial simulates stockinette application to assess if it prevents proximal microbial migration into the sterile field.

A progressive exercise and structured advice program does not improve activity more than structured advice alone following a distal radial fracture: a multi-centre, randomised trial

QUESTION Does a program of exercise and structured advice implemented during the rehabilitation phase following a distal radial fracture achieve better recovery of upper limb activity than structured advice alone? DESIGN A phase I/II, multi-centre, randomised, controlled trial with concealed allocation, assessor blinding and intention-to-treat analysis. PARTICIPANTS Thirty-three adults (25 female, mean age 54 years) following distal radial fracture managed in a cast. INTERVENTION The experimental intervention was a 6-week program of progressive exercise and structured advice implemented over three consultations by a physiotherapist. The control intervention was a program of structured advice only, delivered by a physiotherapist over three consultations. OUTCOME MEASURES The primary outcome was upper limb activity limitations, assessed by the Patient-Rated Wrist Evaluation and the shortened version of the Disabilities of the Arm, Shoulder and Hand outcome measure (QuickDASH). The secondary outcomes were wrist range of movement, grip strength and pain. All measures were completed at baseline (week 0), after the intervention (week 7) and at 6 months (week 24). RESULTS There were no significant between-group differences in upper limb activity as measured by the Patient-Rated Wrist Evaluation at week 7 and week 24 assessments (mean difference -4 units, 95% CI -10 to 2; mean difference 0 units, 95% CI -3 to 3, respectively), or QuickDASH at week 7 and week 24 assessments (mean difference -5 units, 95% CI -16 to 6; mean difference 0.3 units, 95% CI -6 to 7, respectively). The secondary outcomes did not demonstrate any significant between-group effects. CONCLUSION The prescription of exercise in addition to a structured advice program over three physiotherapy consultations may convey no extra benefit following distal radial fracture managed in a cast.

Twelve-month mortality and functional outcomes in hip fracture patients under 65 years of age

INTRODUCTION There has been a recent call for improved functional outcome reporting in younger hip fracture patients. Younger hip fracture patients represent a different population with different functional goals to their older counterparts. Therefore, previous research on mortality and functional outcomes in hip fracture patients may not be generalisable to the younger population. The aims of this study were to report 12-month survival and functional outcomes in hip fracture patients aged <65 years and predictors of functional outcome. METHODS Hip fracture patients aged <65years (range 17-64) registered by the Victorian Orthopaedic Trauma Outcomes Registry over four years were included and their 12-month survival and functional outcomes (Extended Glasgow Outcome Scale) reported. Ordered multivariable logistic regression was used to identify predictors of higher function. RESULTS There were 507 patients enrolled in the study and of the 447 patients (88%) with 12-month outcomes, 24 (5%) had died. The majority of patients had no comorbidities or pre-injury disability and were injured via road trauma or low falls. 40% of patients sustained additional injuries to their hip fracture. 23% of patients had fully recovered at 12 months and 39% reported ongoing moderate disability. After adjusting for all key variables, odds of better function 12-months post-fracture were reduced for patients with co-morbidities, previous disability or additional injuries, those receiving compensation or injured via low falls. CONCLUSIONS While 12-month survival rates were satisfactory in hip fracture patients aged under 65 years, their functional outcomes were poor, with less than one quarter having fully recovered 12 months following injury. This study provides new information about which patients may have difficulty returning to their pre-injury level of function. These patients may require additional or more intensive post-discharge care in order to fulfil their functional goals and continue to contribute productively to society.

Twelve-month work–related outcomes following hip fracture in patients under 65 years of age

INTRODUCTION Recent research has highlighted the need for improved outcome reporting in younger hip fracture patients. For this population, return to work (RTW) is a particularly important measure against which to evaluate treatment outcomes. However, to date, only two small studies have reported RTW outcomes in young hip fracture patients and neither investigated factors predictive of RTW. The aims of this study were to report return to work (RTW) status and predictors of RTW 12 months after hip fracture in patients <65 years. METHODS Two hundred and ninety-one adults aged <65 years, admitted with hip fractures between July 2009 and June 2013 and registered by the Victorian Orthopaedic Trauma Outcomes Registry (VOTOR) were included in this prospective cohort study. Twelve-month return to work status was collected through structured telephone interviews conducted by trained interviewers. Multivariate logistic regression was used to identify demographic and injury variables that were important predictors of 12-month work status. RESULTS Sixty-five per-cent of patients had returned to work 12 months after hip fracture (62% of whom had an isolated hip fracture and 38% of whom had additional injuries). Relative to patients aged 16-24 years, odds of RTW was reduced by 78%-89% for each 10-year increase in age (p=0.02). Relative to patients employed as managers/administrators/professionals, odds of RTW were 68% to 95% lower for all other workers (p<0.001). For those reporting a pre-injury disability, odds of RTW were 79% lower compared to those without disability (p=0.004) and 69% lower for patients with multiple injuries compared to isolated hip fracture patients (p=0.002). Finally, patients compensated by a work or transport insurer had a 67% lower odds of RTW relative to patients who were not compensated (p=0.02). CONCLUSIONS Approximately one third of patients <65years had not returned to work 12 months after hip fracture. Patients who are older, have multiple injuries or pre-existing disabilities or who work in more physical occupations may need more assistance to RTW following hip fracture. The compensation system should be examined to determine why compensated patients may be at risk of poor RTW outcomes.

Twelve-month outcomes following surgical repair of the Achilles tendon

INTRODUCTION Incidence of Achilles tendon rupture (ATR) has increased over recent years, and debate regarding optimal management has been widely documented. Most papers have focused on surgical success, complications and short term region-specific outcomes. Inconsistent use of standardised outcome measures following surgical ATR repair has made it difficult to evaluate the impact of ATR on a patients health status post-surgery, and to compare this to other injury types. This study aimed to report the frequency of surgical repairs of the Achilles tendon over a five-year period within an orthopaedic trauma registry, and to investigate return to work (RTW) status, health status and functional outcomes at 12 months post-surgical repair of the Achilles tendon. METHODS Two hundred and four adults registered by the Victorian Orthopaedic Trauma Outcomes Registry (VOTOR) who underwent surgical repair of the Achilles tendon between July 2009 and June 2014 were included in this prospective cohort study. The Extended Glasgow Outcome Scale (GOS-E), 3-level European Quality of Life 5 Dimension measure (EQ-5D-3L), and RTW status 12 months following surgical ATR repair were collected through structured telephone interviews conducted by trained interviewers. RESULTS At 12 months, 92% of patients were successfully followed up. Of those working prior to injury, 95% had returned to work. 42% of patients reported a full recovery on the GOS-E scale. The prevalence of problems on the EQ-5D-3L at 12 months was 0.5% for self-care, 11% for anxiety, 13% for mobility, 16% for activity, and 22% for pain. 16% of patients reported problems with more than one domain. The number of surgical repairs of the Achilles tendon within the VOTOR registry decreased by 68% over the five-year study period. CONCLUSIONS Overall, patients recover well following surgical repair of the Achilles tendon. However, in this study, deficits in function persisted for over half of patients at 12 months post-injury. The decreased incidence of surgical Achilles tendon repair may reflect a change in practice at VOTOR hospitals whereby surgery may be becoming less favoured for initial ATR management.

Distal radial fractures in children: risk factors for redisplacement following closed reduction.

Background: Distal radial fractures represent one of the most common fractures in children with the majority treated by closed reduction and cast application. Redisplacement after manipulation can occur resulting in potential poor outcome. We performed a prospective study of children undergoing closed reduction of distal radial fracture and evaluated a range of possible risk factors contributing to loss of reduction. Methods: The prospective study included 135 displaced distal radial fractures. There were 48 girls (36%) and 87 boys (64%), with a mean age of 9.9 years (range, 3 to 17 y). The risk factors for redisplacement, which were evaluated, were age, sex, location of the fracture, preoperative fracture displacement, presence of ulna fracture, grade of surgeon, quality of reduction, quality of plaster, and residual postreduction displacement. Results: Redisplacement occurred in 39 of 135 cases (28.8%). Initial complete displacement was the most important risk factor for loss of reduction (odds ratio, 6.94; P=0.001). Completely displaced fractures were 7 times more likely to redisplace than fractures with some bony contact or no translation. Achievement of anatomic reduction decreases the risk of redisplacement (odds ratio, 0.29; P=0.046). Ten of the 39 fractures that lost position needed a second procedure (7.4%). Conclusions: Completely displaced distal radial fractures that cannot be anatomically reduced have a high risk of redisplacement after closed reduction. Only a small number of fractures that lose reduction will require a second intervention. Level of Evidence: Level II.
