Objectives:
Current literature describes improved clinical outcomes and a minor rate of pseudoarthrosis following operatively treated clavicular fractures. We investigated the feasibility of using a standard 3.5 mm AO locking compression plate (LCP) of adequate length for the stabilisation of mid-shaft fractures of the clavicle.
Methods:
The length and acromial and diaphyseal curvature depths were measured in 49 cadaveric clavicles. We then assessed how well the 6, 7, 8 and 9-hole plates fit on the clavicles.
Results:
The mean clavicular length was 155±12 mm, with a mean acromial curvature of 18.1±3.7 mm and a mean diaphyseal curvature of 12 mm±4 mm. The optimum plate for the clavicle was a 7-hole LCP, providing adequate fixation in 48 of the 49 clavicles.
Conclusion:
The described technique for plate osteosynthesis of the clavicle with AO locking compression plate is feasible and results in a biomechanically strong construct for mid-shaft fractures. With the use of a locking plate, comminuted fractures may be bridged without a reduction in the strength of the construct.

Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
