Antegrade femoral nailing in the lateral decubitus position: a case series, technical tips and review of literature.

BACKGROUND: Femoral intramedullary nailing is traditionally performed with the patient supine on a fracture table. We aimed to describe a case series of femoral intramedullary nailing for fracture in the lateral position, with discussion of the operative technique. METHODS: A retrospective analysis identified 52 patients who underwent femoral intramedullary nailing performed in a lateral position without traction over a 5-year period at a single level 1 trauma center. Medical records were reviewed for demographics, blood loss including need for transfusion, operative duration, complications, length of stay, fracture union, re-operation and death. RESULTS: There were 24 subtrochanteric, 16 peri-trochanteric and 12 diaphyseal femoral fractures. Mean operative time was 136.2 ± 101.4 min with a mean estimated blood loss of 372.5 ± 349.6 ml. Seventeen patients required blood transfusion. Mean length of stay was 10.3 ± 8.1 days. There were 3 (5.8%) surgical (compartment syndrome, infection and retained drain) and 12 (23.1%) medical complications, with a 30-day mortality rate of 3.8% (2). Mean follow-up was 9.9 ± 8.7 months. The union rate was 94.2% (49) and 3.8% (2) patients required revision fixation (hardware exchange for irritation and exchange nailing for non-union). Discharge destination was home, rehabilitation center and specialized nursing facility in 21 (40.4%), 16 (30.8%) and 15 (28.8%) patients, respectively. DISCUSSION AND CONCLUSION: Femoral intramedullary nailing in the lateral decubitus position is a useful technique of managing peri-trochanteric, subtrochanteric and diaphyseal femoral fractures. We describe a known technique with technical tips, which has distinct advantages over traditional supine positioning especially in certain patient and fracture types. In addition, operative times, blood loss, length of stay, revision and outcomes were comparable to the literature.

Pipkin type IV femoral head fractures: a case series and review of literature.

INTRODUCTION: Femoral head fractures with associated acetabular fractures are uncommon injuries usually resulting from high-energy mechanisms such as motor vehicle collisions. Outcomes of Pipkin type IV fractures have been historically poor, with high rates of osteonecrosis, post-traumatic arthritis, and heterotopic ossification. The objective of this study was to define the outcomes of operatively treated Pipkin type IV fractures In addition, we reviewed the available literature of this uncommon injury pattern. METHODS: A retrospective chart review at a single level 1 trauma center from 2007 to 2016 identified 10 patients with Pipkin IV femoral head fractures. Demographic information, fracture type, associated injuries, operative details, and complications were evaluated. Clinical and radiological outcomes were assessed at latest follow-up including conversion to total hip arthroplasty. RESULTS: Six of the seven patients were treated with open reduction and internal fixation of the femoral head fracture and acetabular fracture through a Kocher-Langenbeck approach aided by a trochanteric flip and one had fragment excision. Six patients (87.5%) developed post-traumatic arthritis. Four (57.1%) later underwent conversion to total hip arthroplasty (THA) a mean of 20.5 months after index procedure. CONCLUSION: Our study shows a rate of osteonecrosis and osteoarthritis that is even higher than the previously reported studies. The former may relate to longer-term follow-up and the latter possibly due to associated comminuted posterior wall fracture.
