Randomized Controlled Trial Multicenter StudyStudy to prospectively evaluate reamed intramedually nails in patients with tibial fractures (S.P.R.I.N.T.): study rationale and design.
Surgeons agree on the benefits of operative treatment of tibial fractures - the most common of long bone fractures - with an intramedullary rod or nail. Rates of re-operation remain high - between 23% and 60% in prior trials - and the two alternative nailing approaches, reamed or non-reamed, each have a compelling biological rationale and strong proponents, resulting in ongoing controversy regarding which is better. ⋯ The primary outcome was re-operation to promote healing, treat infection, or preserve the limb (fasciotomy for compartment syndrome after nailing). The primary outcome was a composite comprising the following re-operations: bone grafts, implant exchanges, and dynamizations, in patients with fracture gaps less than 1 cm post intramedullary nail insertion. Infections and fasciotomies were considered events irrespective of the fracture gap. We planned a priori to conduct a subgroup analysis of outcomes in patients with open and closed fractures. S.P.R.I.N.T is the largest collaborative trial evaluating alternative orthopaedic surgical interventions in patients with tibial shaft fractures. The methodological rigor will set new benchmarks for future trials in the field and its results will have important impact on patient care. The S.P.R.I.N.T trial was registered [ID NCT00038129] and received research ethics approval (REB#99-077).

Multicenter Study Comparative StudyThe surgical approach for locking plate osteosynthesis of displaced proximal humeral fractures influences the functional outcome.
This study evaluated the influence of the surgical approach for locking plate osteosynthesis in proximal humeral fractures during a 1-year period. We performed a comparative study in 83 patients to evaluate possible benefits for an early functional result for function, pain, activity levels, radiographic evaluation, and complications. In 39 cases, the extended anterolateral deltoid-splitting approach was used (group DS); in 44 cases, the deltopectoral approach was used (group DP). ⋯ One case of avascular necrosis was observed in group DS and 3 in group DP. We conclude that the choice of approach for exposure of the proximal humerus region may influence the functional outcome. Stable osteosynthesis is important, but the outcome of operatively treated proximal humerus fractures is dependent on soft tissue management as well.

Randomized Controlled Trial Multicenter Study Comparative StudyPercutaneous screw fixation versus conservative treatment for fractures of the waist of the scaphoid: a prospective randomised study.
We randomly allocated 60 consecutive patients with fractures of the waist of the scaphoid to percutaneous fixation with a cannulated Acutrak screw or immobilisation in a cast. The range of movement, the grip and pinch strength, the modified Green/O'Brien functional score, return to work and sports, and radiological evidence of union were evaluated at each follow-up visit. Patients were followed sequentially for one year. ⋯ Patients treated by operation had a more rapid return of function and to sport and full work compared with those managed conservatively. There was a very low complication rate. We recommend that all active patients should be offered percutaneous stabilisation for fractures of the waist of the scaphoid.

Multicenter StudyA method for internal fixation of unstable distal clavicle fractures: early observations using a new technique.
Unstable distal clavicle fractures often require open reduction and internal fixation. A variety of fixation methods have been used and are currently in use. None of the current fixation methods seem to be without problems. We present a new technique and early observations using a distal radius locking T-plate normally used for fixation of distal radius fractures.

Radiographic outcomes of intertrochanteric hip fractures treated with the trochanteric fixation nail.
Intertrochanteric hip fractures have become more common as the elderly population continues to increase, and surgical stabilisation of these fractures remains a persistent challenge. The purpose of this study was to analyse the ability of a new helical blade device to stabilise intertrochanteric hip fractures, and to further determine which factors are important in implant stability. ⋯ Subtle migration ( approximately 2mm) of the tip of the blade within the femoral head occurred in all fractures, but this did not preclude maintenance of reduction and fracture healing, and was not predicted by fracture type, reduction quality, age, or gender. More telescoping occurred in unstable compared to stable fractures, but this averaged 4mm and did not affect stable fixation or fracture healing. All position changes occurred within the first 6 weeks postoperatively, with no subsequent detectable migration or telescoping. Clinical correlations will be needed in the future to determine the significance of small amounts of migration or differences in telescoping, but this device appears to provide effective fixation in both stable and unstable intertrochanteric hip fractures.
