[Reconstruction of a fracture of the posterior acetabular wall with Pipkin fracture and lesion of the sciatic nerve after dorsal hip dislocation].

A 50-year-old male suffered a crash landing while paragliding and sustained a posterior dislocation of the hip with a Pipkin fracture type 4 (fracture of the posterior acetabular wall and Pipkin fracture type 2) and a lesion of the sciatic nerve. After primary treatment in an external hospital, the patient was transferred to this hospital 4 days following the trauma. An operative stabilization of the acetabular fracture and the Pipkin fracture was performed using a trochanter flip osteotomy. Despite a large central defect of the femoral head it was decided to attempt a reconstruction. Following fixation of the Pipkin fragment an autologous bone graft harvested from the intertrochanteric region was used to fill the defect. Subsequently, a collagen matrix was applied onto the filled defect and a perineural adaptation of the sciatic nerve was performed.
