Abstract. Objectives. We aimed to evaluate if union of clavicle fractures can be predicted at six weeks post-injury by the presence of bridging callus detected by ultrasound. Methods. Adult patients who sustained a displaced midshaft clavicle were recruited prospectively. We assessed patient demographics, functional scores and radiographic predictors with a standardized protocol at six weeks. Ultrasound evaluation of the fracture site was undertaken to determine if sonographic bridging callus was present. Nonunion was determined by CT scanning at six months post-injury. Clinical features at six weeks were used to stratify patients at high risk of nonunion and a QuickDASH ≥40, fracture movement on examination or absence of callus on radiograph. Results. 112 patients completed follow-up at six months with a nonunion incidence of 17% (n=18/112). Sonographic bridging callus was detected in 62.5% (n=70/112) of the cohort at six weeks post-injury. If present, union occurred in 98.6% of the fractures (n=69/70). If absent, nonunion developed in 40.5% of cases (n=17/42). The sensitivity to predict union with sonographic bridging callus at six weeks was 73.4% and the specificity was 94.4%. Regression analysis found failure to detect sonographic bridging callus at six weeks was associated with nonunion, older age, female sex, and greater overall fracture displacement (Nagelkerke R2=0.60). Of the cohort, 30.4% (n=34/112) had absent sonographic bridging callus at six weeks in combination with one or more of the ‘high risk’ clinical features. If one was present the nonunion rate was 47.1%, increasing to 60% with two risk factors and 100% when combined with all three. Conclusions. Ultrasound can accurately predict fracture healing at six weeks following a displaced midshaft clavicle fracture. When combined with poor clinical recovery this could be used to target patients for early operative intervention. Declaration of Interest.

Background. Clavicle development occurs before the age of 9 in females and 12 in males. Children below the age of 10 with displaced midshaft clavicle fractures recover well with conservative management. However adolescents are more demanding of function and satisfaction following clavicle fractures and may benefit from operative management. Study aims: 1) Perform a systematic review of the current evidence supporting intramedullary fixation of adolescent clavicle fractures. 2) Review current management in a major trauma center (MTC) with a view to assess feasibility for a randomised controlled trial (RCT). Methods. The MEDLINE, EMBASE and AMED databases were searched in October 2014 to identify all English language studies evaluating intramedullary fixation in children aged 10–18 years using MeSH terms. Data was extracted using a standardised data collection sheet and studies were critically appraised by aid of the PRISMA checklist. All patients aged 9–15 attending an MTC receiving clavicle radiographs in 2014 were retrospectively reviewed for type of fracture, management and outcome. Results. Literature search identified 54 articles. After application of exclusion criteria 3 studies were selected for final review. 47 adolescent patients received intramedullary clavicle fixation from a prospective and two retrospective case series. 61 adolescents presented to our unit with a clavicle fracture in 2014, 2 were lost to follow-up, 54 were managed non-operatively, 3 received titanium-elastic nailing, 1 plate osteosynthesis and 1 bone suture. 0 and 19 patients reported a palpable lump, mean time to pain resolution was 4 and 6 weeks and time to full range of motion was 4 and 5 weeks following operative and conservative management respectively. All patients reached radiographic union. Conclusion. Current evidence supporting intramedullary fixation of clavicle fractures in adolescents is poor. There remains clinical equipoise on the best management of these patients, however they are predominantly treated conservatively. A future multi-center RCT may be feasible. Level of Evidence. 1
