Abstract
INTRODUCTION: Uncommon but increasingly diagnosed, ipsilateral femoral neck and shaft fracture represents a complex injury pattern with challenging management. The conundrum involves optimal diagnostic modality, timing of surgery, sequence of fixation, and the choice of implant. METHODOLOGY: A retrospective review was conducted at a Level-I trauma centre to assess the outcome of concomitant femoral neck and shaft fractures managed with various implants and attempt to provide solutions to the aforementioned queries. The time between injury and definitive surgery, choice of implant, sequence of fixation, time to fracture union, and complications were documented and analyzed. RESULTS: A total of 46 patients were included in the study wherein associated neck fracture was identified preoperatively in 93.5% of patients. In patients with isolated limb fractures, the mean time to surgery was 16.7 ± 5 h whereas patients with polytrauma witnessed an average delay of 4.6 days before fracture fixation. 72% of patients were managed by dual implants and in the remaining both the fractures were addressed using a single implant with no union time difference amongst implants. The mean time to the union for neck fracture was 21.7 weeks and 24.2 weeks for shaft femur fracture. 21.7% patients developed delayed union of fracture shaft femur and infection complicated 11% shaft fractures. CONCLUSION: Although, 6% neck fractures were missed in the series, we advocate that careful pre/intra/post-operative fluoroscopic evaluation of the femoral neck along with a low threshold for a pre-operative CT scan remains the optimal diagnostic modality while avoiding universal employment of computed tomography (CT). With fracture union being unaffected by implant choice, authors suggest that anatomical fixation of the femoral neck is of paramount importance followed by restoration of the length, alignment and rotation of the femoral shaft, and the implant selection primarily depends on surgeon's experience and the pattern of injury.
