[Current therapy options for fractures of the femoral head].
Fractures of the femoral head (Pipkin fractures) are relatively uncommon. In cases of immediate, gentle reposition and considerate soft tissue treatment during operative treatment, Pipkin 1 and 2fractures can heal with good long-term results. However, some long-term problems regularly occur. Conservative therapy is possible in cases of anatomic articulation or the presence of only very small fragments that do not compromise articulation after closed reduction. Differentiated indications for conservative treatment in Pipkin 1 and Pipkin 2 fractures can result in a better outcome than operative treatment. All other fractures should be treated operatively. The approach has to be adapted to fragment size and location. Small fragments in Pipkin 1 fractures can simply be removed, but larger fragments in Pipkin 1 and Pipkin 2 fractures should be fixed, preferably via an anterior approach. Pipkin 3 fractures generally require total hip arthroplasty. Pipkin 4 fractures have a relatively poor outcome. The strategy of treatment depends on the necessity of operative fixation of the acetabular fracture and the size of the femoral fragment. The anterior approach is preferred in cases of stable joint situations with only a small acetabular rim fragment, and in cases of instability the dorsal approach is preferred. Surgical luxation can be advantageous for the treatment of Pipkin 4 fractures.
