To test whether a novel guide template we designed can facilitate accurate insertion of antegrade lag screws in the fixation of acetabular posterior column fractures. ⋯ Antegrade lag screws can be more accurately put into the posterior column of the acetabulum with the help of this navigation template.

This study sought to determine the safety limits for performing a femoral bone tunnel to reconstruct the knee anterolateral ligament (ALL) by establishing its distance from the lateral collateral ligament (LCL) and the popliteus muscle tendon (PT) on the lateral femoral condyle. ⋯ Performing a tunnel in the center of the ALL may cause an iatrogenic injury to the LCL origin. No cases of PT injury are expected to occur with drills smaller than 10 mm.

Sternal fractures are rare with 3-8 % out of the total number of trauma cases mostly caused by direct impact to the anterior chest wall. Most cases described are due to motor vehicle crash either caused by direct impact to the steering wheel or by the seat belt. Fractures mainly occur to the sternal body. Only rarely are cases of manubrium fractures described in literature, for example, in relationship with a direct impact to the shoulder which caused an oblique fracture near to the sternoclavicular joint. Three patients with profoundly dislocated oblique manubrium fracture were admitted to our Level I Trauma Center in 2012 and 2013. Those patients suffered from instability of the upper sternum and the shoulder girdle. ⋯ A total of 16.5 % of sternal fractures were localized at the manubrium, mostly caused by seat belt. Fractures without significant dislocation seemed to be stable and healed well under conservative treatment. Dislocation in this region leads to unstable shoulder girdle. Anterior plating provides sufficient stabilisation and allowed consolidation.
