Introduction and aims. Cast immobilisation of paediatric forearm fractures has traditionally used plaster of Paris. Recently, synthetic casting materials have been used. There have been no studies comparing the efficacy of these two materials. The aim of this study is to investigate whether one material is superior for paediatric forearm fracture management. Methods. A single-centre prospective randomised trial of patients presenting to the Women's and Children's Hospital with acute fractures of the radius and/or ulna was undertaken. Patients were enrolled into the study on presentation to the Emergency Department and randomised by sealed envelope into either a fiberglass or plaster of Paris group. Patients then proceeded to a standardised method of closed reduction and cast immobilisation. Clinical follow-up occurred at one and six weeks post-immobilisation. A patient satisfaction questionnaire was completed following cast removal at six weeks. All clinical complications were recorded and cast indexes were calculated. Results. Initially 50 patients were recruited to the study, with equal randomisation. There were no significant differences between the patient demographics of the two groups. The results from this sample indicated an increase in clinical complications involving the plaster of Paris casting group. These complications included soft areas of plaster requiring revision, loss of reduction with some requiring re-manipulation and a high rate of cast spliting due to material swelling. The fractures that loss reduction had increased cast indices. Fibreglass casts were also preferred by patient and their families, with many observational comments regarding the light-weight and durable nature of the material. Conclusions. Cast immobilisation of paediatric forearm fractures is a common orthopaedic treatment. There is currently no evidence regarding the best material for casting. This study suggests that both clinical outcomes and patient satisfaction are superior with fiberglass casts, we are continuing this study to enable greater power with our results

Infection and re-fracture are well-described complications following open paediatric forearm fractures. The purpose of this paper is to determine if patient, injury, and treatment characteristics can be used to predict the occurrence of these complications following the surgical management of paediatric open forearm fractures. This is an IRB-approved retrospective review at a single-institution paediatric level 1 trauma centrefrom 2007–2013 of all open forearm fractures. Medical records were reviewed to determine the type of open fracture, time to administration of initial antibiotics, time from injury to surgery, type of fixation, length of immobilisation, and complications. Radiographs were studied to document fracture characteristics. 262 patients with an average age of 9.7 years were reviewed. There were 219 Gustillo-Anderson Type 1 open fractures, 39 Type 2 fractures, and 4 Type 3 fractures. There were 9 infections (3.4%) and 6 re-fractures (2.3%). Twenty-eight (10.7%) patients returned to the operating room for additional treatment; 21 of which were for removal of implants. Contaminated wounds, as documented within the medical record, had a greater chance of infection (21% vs 2.2%, p=0.002). No difference in infection rate was seen with regard to timing of antibiotics (p=0.87), timing to formal debridement (p=0.20), Type 1 versus Type 2 or 3 open fractures (3.4% vs 5.0%, p=0.64), 24 hours vs. 48 hours of post-operative IV antibiotics (5.2% vs 3.5%, p=0.53), or when comparing diaphyseal, distal, and Monteggia fracture patterns (3.6 vs 2.9% vs 5.9%, p=0.81). There was no difference in infection rate when comparing buried or exposed intramedullary implants (3.5% vs 4.2%, p>0.99). Rate of re-fracture was not increased based on type of open wound (p>0.99) or fracture type (0.4973), although 5 of the 6 re-fractures were in diaphyseal injuries. In this series of open paediatric both bone forearm fractures, initial wound contamination was a significant risk factor for subsequent infection. The rate of infection did not vary with timing of antibiotics or surgery, type of open fracture, or length of post-operative antibiotics. A trend to higher re-fracture rates in diaphyseal injuries was noted. Surgeons should consider planned repeat irrigation and debridement for open forearm fractures with obviously contaminated wounds to reduce the subsequent infection risk

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

Purpose:. Paediatric forearm fractures are commonly seen and treated by closed reduction and plaster cast application in theatre. Historically, cast application has been subjectively evaluated for its adequacy in maintaining fracture reduction. More recently emphasis has been placed on objectively evaluating the adequacy of cast application using indicators such as the Canterbury index (CI). The CI has been used in predicting post-reduction, re-displacement risk of patients by expressing the casting and padding indices as a ratio. The CI has been criticized for not including cast 3 point pressure, fracture personality and lack of standardization of X-ray views as well as practical requirement of physical measurement using rulers. The aim of this study was to determine whether subjective evaluation of these indices, on intra-operative fluoroscopy and the day 1 to 7 postoperative X-ray, was accurate in predicting a patient's ultimate risk of re-displacement, following reduction and casting. Materials and Methods:. In total, 22 X-rays from 11 patients were evaluated by 20 orthopaedic registrars and 8 consultants, before and after a tutorial on the Canterbury index. Results:. Formal tutorial did not show an increased subjective predictive accuracy. No clear correlation could be demonstrated between CI and the clinical outcome. Conclusion:. Value of the CI in clinical practice is doubtful due to various confounding factors. The CI has been used due to lack of other available systems, and ideally a system should be sought which incorporates fracture personality, cast 3 point pressure and standardisation of X-Rays

We present an objective method for predicting the redisplacement of paediatric forearm and wrist fractures. Novel radiographic measurements were defined and their value assessed for clinical decision making. In Phase I of the study we defined the cast index and padding index and correlated these measurements with the incidence of fracture redisplacement. Phase II assessed these indices for their value in clinical decision making. Cast Index (a/b) is the ratio of cast width in lateral view (a) and the width of the cast in AP view (b). Padding Index (x/y) isthe ratio of padding thickness in the plane of maximum deformity correction (x) and the greatest interosseous distance (y) in AP view. The sum of cast index and padding index was defined as the Canterbury Index. In Phase I, 142 children's radiographs were analysed and a statistically significant difference was identified between redisplacement and initial complete off-ending of the bones, cast index > 0.8 and padding index of > 0.3. There was no significant association with age, fracture location, seniority of surgeon or angulation. In Phase II, radiographs of 5 randomly selected cases were presented to 40 surgeons (20 consultants & 20 registrars). Following an eyeball assessment they were asked to measure the cast index and padding index (after instruction). With eyeballing the consultants predicted 33% and registrars 25% of the cases that redisplaced. After learning to measure the indices the accuracy increased to 72% for consultants and 81% for registrars (p<0.001). We conclude that the cast index, padding index and Canterbury Index are validated tools to assess plaster cast quality and can be used to predict redisplacement of paediatric forearm fractures after manipulation. They can easily be taught to orthopaedic surgeons and are more accurate than eyeballing radiographs in the clinical setting. Redisplacement can be predicted if cast index > 0.8, padding index > 0.3 and Canterbury Index > 1.1

Aims. To evaluate the results of Elastic Stable Intramedullary Nailing (ESIN) for displaced, unstable paediatric forearm diaphyseal fractures. Method. A retrospective, consecutive series study of 60 patients treated with ESIN between February 1996 and July 2005. Results. There were 43 (72%) boys and 17 (28%) girls with median age of 11.5 years (range: 2.6-15.9). 54 (90%) patients had a closed injury and 6 (10%) sustained a Grade I open injury. Seven patients had an isolated radius fracture. 49 (82%) fractures were stabilised with both bone ESIN, 10 (16%) with radial and one with isolated ulnar ESIN by standard technique under tourniquet control. All but two patients were protected with an above elbow cast. Thirty-six cases (60%) were primary procedures and 24 (40%) were performed due to re-displacement following a MUA. 36 patients (60%) required a minimal open reduction. Average hospital stay was 1.8 days (1-8 days). Average length of immobilisation was 5.4 weeks (3-9 weeks). Average time for clinical fracture union was 5.7 weeks (3-13 weeks). ESIN were removed after mean period of 33.8 weeks (approx: 7.9 months). One patient had a forearm compartment syndrome and required formal fasciotomy. One patient had ulnar delayed union and one had ulnar non-union. Five patients had transient superficial radial nerve neuropraxia. Ten had soft tissue irritation leading to early nail removal in two patients and two had superficial wound infection. Three patients sustained a re-fracture with the nail in situ following a new injury. 53 (88%) patients had full elbow and wrist movements on discharge. Seven patients had restriction of forearm rotations of less than 15°. Conclusion. Good clinical outcome, transitory and modest complications; quick and safe nail removal; and better cosmesis compared to plating makes ESIN an attractive treatment option for displaced, unstable paediatric forearm diaphyseal fractures
