PurposeThe combination of ipsilateral femoral neck and shaft fractures remains a treatment challenge in orthopedic surgery because both fracture types constitute separate entities and require specific treatment concepts.Material And MethodsIn a case control study, incidence, treatment strategies, and outcomes of this injury were analyzed. All patients with femoral fractures treated between 1 January 2001 and 31 July 2007 at a level I trauma center were included in the study.ResultsTwenty-one out of 1,935 patients (1.1%) sustained 22 combined fractures of the femoral neck and shaft. Also considering the combination of femoral shaft fractures with fractures of the acetabulum and the distal femur (knee), the proportion of chain injuries of the femur was 3.1%. The rate of multiply injured patients in the group of patients with ipsilateral femoral neck and shaft fractures was 64%. The majority of the patients could be treated with a single implant for both fracture components. The leading fracture component was the femoral neck fracture in eight cases. All fractures consolidated after 4.7 months on average; one pseudarthrosis of the femoral neck was observed. All fractures were discovered in the course of primary diagnostic measures; in 73% of the patients, a computed tomography (CT) body scan was done. Fifty-nine percent of the patients with ipsilateral femoral neck and shaft fractures received primary definitive operative care. Complications included two torsional failures that needed correction and one case of postoperative infection that was easily treated.ConclusionTreatment of ipsilateral femoral neck and shaft fractures is still demanding, but diagnosis has improved with regular use of CT body scans in the management of multiply injured patients. Furthermore, possibilities for operative treatment have been advanced by the introduction of the long proximal femoral nail and the antegrade femoral nail, two implants supporting stabilization of these fracture entities.
