Aims. It is not clear which type of casting provides the best initial treatment in adults with a distal radial fracture. Given that between 32% and 64% of adequately reduced fractures redisplace during immobilization in a cast, preventing redisplacement and a disabling malunion or secondary surgery is an aim of treatment. In this study, we investigated whether circumferential casting leads to fewer fracture redisplacements and better one-year outcomes compared to plaster splinting. Methods. In a pragmatic, open-label, multicentre, two-period cluster-randomized superiority trial, we compared these two types of casting. Recruitment took place in ten hospitals. Eligible patients aged ≥ 18 years with a displaced distal radial fracture, which was acceptably aligned after closed reduction, were included. The primary outcome measure was the rate of redisplacement within five weeks of immobilization. Secondary outcomes were the rate of complaints relating to the cast, clinical outcomes at three months, patient-reported outcome measures (PROMs) (using the numerical rating scale (NRS), the abbreviated version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH), and Patient-Rated Wrist/Hand Evaluation (PRWHE) scores), and adverse events such as the development of compartment syndrome during one year of follow-up. We used multivariable mixed-effects logistic regression for the analysis of the primary outcome measure. Results. The study included 420 patients. There was no significant difference between the rate of redisplacement of the fracture between the groups: 47% (n = 88) for those treated with a plaster splint and 49% (n = 90) for those treated with a circumferential cast (odds ratio 1.05 (95% confidence interval (CI) 0.65 to 1.70); p = 0.854). Patients treated in a plaster splint reported significantly more pain than those treated with a circumferential cast, during the first week of treatment (estimated mean NRS 4.7 (95% CI 4.3 to 5.1) vs 4.1 (95% CI 3.7 to 4.4); p = 0.014). The rate of complaints relating to the cast, clinical outcomes and PROMs did not differ significantly between the groups (p > 0.05). Compartment syndrome did not occur. Conclusion. Circumferential casting did not result in a significantly different rate of redisplacement of the fracture compared with the use of a plaster splint. There were comparable outcomes in both groups.

Aims

To compare operative and nonoperative treatment for displaced distal radius fractures in patients aged over 65 years.

Aims

The purpose of this study was to compare the prevalence of hip displacement and dislocation in a total population of children with cerebral palsy (CP) in Scotland before and after the initiation of a hip surveillance programme.

Aims

The aim of this prospective randomised controlled trial was to compare non-operative and operative management for acute isolated displaced fractures of the olecranon in patients aged ≥ 75 years.

The aim of this study is to discuss the results of intramedullary devices in the management of paediatric radial neck fractures and to suggest methods to avoid the pitfalls of the technique. 30 patients with isolated Judet III and IV fractures were included in this retrospective study. The method of reduction was reviewed. The final results were graded using the Metaizeau functional scoring system and Oxford Elbow score. Intramedullary K wires were used in 10 patients and blunt tipped TENS nails in 20 patients. The complications seen were radiocapitellar joint penetration-6 cases at mean 4.87 weeks, redisplacement − 6, radial epiphyseal sclerosis − 5 and heterotopic ossification − 1 case. The functional result was good to excellent in 24 of 30 cases(80%). The mean Oxford Elbow score was 44.32. The mean follow-up was 40.11 months. Intramedullary K wires may result in radiocapitellar joint penetration. Blunt tipped devices should not be used as purely fixation devices as they may not prevent redisplacement. Minimal redisplacement does not affect the functional outcome. Regular follow-up until atleast 6 weeks is essential. Patients who have a Judet IV fracture and need open reduction should be closely followed up and given a guarded prognosis

The purpose of the study was to identify risk factors that are associated with re-displacement of the hip after surgical reconstruction in cerebral palsy. Retrospective review of children with cerebral palsy who had hip reconstruction with proximal femoral varus derotation osteotomy (VDRO) and Dega-type pelvic osteotomy, between 2005–2012, at a UK and European institution, was performed. Patient demographics, GMFCS, clinical and radiological outcome were assessed as well as the presence of pelvic obliquity and significant scoliosis (Cobb angle > 10 degrees). Redisplacement was defined as Reimer's Migration Index (MI) >30% at final follow-up. Logistic regression analysis was used to assess which factors were predictive of redisplacement and adjusted for clustered variables (α = 0.05). Eighty hips were identified in 61 patients. The mean age at surgery was 8.8 years (± 3.3). Mean MI pre-op was 68% (± 23%) and post-op was 8% (± 12%). At a mean follow-up, of 3.2 years (± 2.0), 23 hips had a MI >30%. Of these; five were symptomatic, and one had required a salvage procedure. Metalwork removal was undertaken in 14 hips. Logistic regression demonstrated that the pre-operative MI and the percentage of acute correction were significant predictors of re-displacement. If the pre-operative MI was greater than 65 percent, the odds ratio (OR) for redisplacement was 5.99 (p = 0.04). If correction of the MI was less than 90% of the pre-operative MI, the OR for re-displacement was 4.6 (p = 0.03). Age at the time of surgery, GMFCS, pelvic obliquity and scoliosis were not predictive of re-displacement. These results, firstly, highlight the importance of hip surveillance in children with cerebral palsy to allow timely intervention to ensure adequate radiological outcomes. Secondly, as in developmental hip dysplasia, full concentric reduction is essential to reduce the risk of re-displacement, with its associated clinical consequences

Distal radius and ulna fractures are a common paediatric injury. Displaced or angulated fractures require manipulation under anaesthetic (MUA) with or without Kirchner (K) wire fixation to improve alignment and avoid malunion. After treatment a proportion redisplace requiring further surgical management. This study aimed to investigate whether the risk of redisplacement could be reduced by introducing surgical treatment guidelines to ascertain whether MUA alone or the addition of K wire fixation was required. A cohort of 51 paediatric forearm fractures managed either with an MUA alone or MUA and K wire fixation was analysed to determine fracture redisplacement rates and factors which predisposed to displacement. Guidelines for optimal management were developed based on these findings and published literature and implemented for the management of 36 further children. A 16% post-operative redisplacement rate was observed within the first cohort. Redisplacement was predicted if an ‘optimal reduction’ of less than 5° of angulation and/or 10% of translation was not achieved and no K wire fixation utilised. Adoption of the new guidelines resulted in a significantly reduced redisplacement rate of 6%. Implementation of departmental guidelines have reduced redisplacement rates of children's forearm fractures at Great Western Hospital

The June 2013 Trauma Roundup³⁶⁰ looks at: open foot fractures; the diagnostic accuracy of continuous compartment pressure monitoring; conservative treatment for supracondylar fractures; high complication rates in patellar fractures; vitamin D and fracture; better function with K-wires; and tensionless bands.

Forearm fractures in children have a tendency to displace in a cast leading to malunion with reduced functional and cosmetic results. In order to identify risk factors for displacement, a total of 247 conservatively treated fractures of the forearm in 246 children with a mean age of 7.3 years (sd 3.2; 0.9 to 14.9) were included in a prospective multicentre study. Multivariate logistic regression analyses were performed to assess risk factors for displacement of reduced or non-reduced fractures in the cast. Displacement occurred in 73 patients (29.6%), of which 65 (89.0%) were in above-elbow casts. The mean time between the injury and displacement was 22.7 days (0 to 59). The independent factors found to significantly increase the risk of displacement were a fracture of the non-dominant arm (p = 0.024), a complete fracture (p = 0.040), a fracture with translation of the ulna on lateral radiographs (p = 0.014) and shortening of the fracture (p = 0.019).

Fractures of both forearm bones in children have a strong tendency to displace even in an above-elbow cast. Severe fractures of the non-dominant arm are at highest risk for displacement. Radiographs at set times during treatment might identify early displacement, which should be treated before malunion occurs, especially in older children with less potential for remodelling.

Redisplacement is the most common complication of immobilisation in a cast for the treatment of diaphyseal fractures of the forearm in children. We have previously shown that the three-point index (TPI) can accurately predict redisplacement of fractures of the distal radius. In this prospective study we applied this index to assessment of diaphyseal fractures of the forearm in children and compared it with other cast-related indices that might predict redisplacement. A total of 76 children were included. Their ages, initial displacement, quality of reduction, site and level of the fractures and quality of the casting according to the TPI, Canterbury index and padding index were analysed. Logistic regression analysis was used to investigate risk factors for redisplacement. A total of 18 fractures (24%) redisplaced in the cast. A TPI value of > 0.8 was the only significant risk factor for redisplacement (odds ratio 238.5 (95% confidence interval 7.063 to 8054.86); p < 0.001). The TPI was far superior to other radiological indices, with a sensitivity of 84% and a specificity of 97% in successfully predicting redisplacement. We recommend it for routine use in the management of these fractures in children. Cite this article: Bone Joint J 2013;95-B:563–7

The purpose of this study was to evaluate the risk of late displacement after the treatment of distal radial fractures with a locking volar plate, and to investigate the clinical and radiological factors that might correlate with re-displacement. From March 2007 to October 2009, 120 of an original cohort of 132 female patients with unstable fractures of the distal radius were treated with a volar locking plate, and were studied over a follow-up period of six months. In the immediate post-operative and final follow-up radiographs, late displacement was evaluated as judged by ulnar variance, radial inclination, and dorsal angulation. We also analysed the correlation of a variety of clinical and radiological factors with re-displacement. Ulnar variance was significantly overcorrected (p < 0.001) while radial inclination and dorsal angulation were undercorrected when compared statistically (p <  0.001) with the unaffected side in the immediate post-operative stage. During follow-up, radial shortening and dorsal angulation progressed statistically, but none had a value beyond the acceptable range. Bone mineral density measured at the proximal femur and the position of the screws in the subchondral region, correlated with slight progressive radial shortening, which was not clinically relevant.

Volar locking plating of distal radial fractures is a reliable form of treatment without substantial late displacement.

Purpose

Distal metaphyseal radial fractures are common in the paediatric population and the management of these fractures is controversial. The incidence of re-displacement in the closed management of these fractures is as much as 30% in some studies. Various methods have been described with the view to predict fracture displacement of distal radial fractures in children. One of these indices is the three point index (TPI). This index seeks to assess the adequacy of 3 point moulding and thus predict fracture displacement. It is a calculated ratio that if above 0.8 states that there is an increased risk of fracture re-displacement. The purpose of this study is to assess the accuracy of this index in predicting displacement of distal radial fractures in children.
