Abstract Background The traditional view that the vast majority of midshaft clavicular fractures heal with good functional outcomes following non-operative treatment may be no longer valid for all midshaft clavicular fractures. Recent studies have presented a relatively high incidence of non-union and identified speciic limitations of the shoulder function in subgroups of patients with these injuries. Aim A prospective, multicentre randomised controlled trial (RCT) will be conducted in 21 hospitals in the Netherlands, comparing fracture consolidation and shoulder function after either non-operative treatment with a sling or a plate fixation. Methods/design A total of 350 patients will be included, between 18 and 60 years of age, with a dislocated midshaft clavicular fracture. The primary outcome is the incidence of non-union, which will be determined with standardised X-rays (Antero-Posterior and 30 degrees caudocephalad view). Secondary outcome will be the functional outcome, measured using the Constant Score. Strength of the shoulder muscles will be measured with a handheld dynamometer (MicroFET2). Furthermore, the health-related Quality of Life score (ShortForm-36) and the Disabilities of Arm, Shoulder and Hand (DASH) Outcome Measure will be monitored as subjective parameters. Data on complications, bone union, cosmetic aspects and use of painkillers will be collected with follow-up questionnaires. The follow-up time will be two years. All patients will be monitored at regular intervals over the subsequent twelve months (two and six weeks, three months and one year). After two years an interview by telephone and a written survey will be performed to evaluate the two-year functional and mechanical outcomes. All data will be analysed on an intention-to-treat basis, using univariate and multivariate analyses. Discussion This trial will provide level-1 evidence for the comparison of consolidation and functional outcome between two standardised treatment options for dislocated midshaft clavicular fractures. The gathered data may support the development of a clinical guideline for treatment of clavicular fractures. Trial registration Netherlands National Trial Register NTR2399

The choice of treatment for midshaft clavicular fractures is not straightforward, but depends on fracture characteristics such as comminution, angulation and displacement. An online survey was conducted amongst trauma and orthopaedic surgeons to determine the preferred treatment for midshaft clavicular fractures, based on anteroposterior radiographs, for 17 randomly selected displaced or comminuted midshaft clavicular fractures. The background and experience of the respondents were documented. Data were analyzed using a Generalized Estimating Equations (GEE) model. The 102 respondents preferred non-operative treatment more frequently for displaced fractures than for comminuted fractures (OR 3.24, 95% CI 2.55-4.12). Locking plate fixation was more often preferred over other surgical modalities for comminuted than for displaced fractures (OR 1.50, 95% CI 1.17-1.91). In clinical practice, there is no consensus between surgeons on the choice of treatment for displaced or comminuted midshaft clavicular fractures. This lack of agreement calls for evidence-based treatment guidelines for these fractures.

Unlabelled: Split-thickness skin grafts (STSG) are used for covering large wound beds. This procedure is sometimes postponed due to a positive culture swab. In those cases, prolonged antibiotic therapy is advised. The present study shows that if a temporary cadaveric donor skin has good take, antibiotic therapy is not necessary and a normal STSG can be performed directly with acceptable results., Methods: Cadaveric donor skin was applied in 35 consecutive patients. If the cadaveric donor skin had a good take (adherence) to the wound bed, the patient was scheduled for a STSG. In cases where the cadaveric donor skin failed to take, the definitive skin graft procedure was postponed. In six consecutive cases the cadaveric donor skin was evaluated for possible pathological changes., Results: In 25 out of 35 patients the cadaveric donor skin had full take. In 22 of these 25 patients a STSG was performed, which led to 91% complete graft take rate. These patients were not treated routinely with antibiotics and if they were treated, surgery was not postponed., Conclusion: Delaying STSG while waiting for swab culture results is not necessary if the cadaveric donor skin has good take 3 days after application; in such cases, the take (attachment) of a STSG in a complicated set of patients is > 90%. The cadaveric donor skin, with positive take, showed more granulocytic influx in the epidermal layer and more vitality than those with no adherence to the wound bed. Vascular in-growth was not noted in any of the cases .
