A novel cerclage wiring technique in intertrochanteric femoral fractures treated by intramedullary nails in young adults

摘要

Intertrochanteric femoral fractures (IFFs) in young adults, generally due to severe trauma, are increasingly presented. Different from IFFs in the geriatric population, these fractures in young adults are always comminuted and substantially displaced. Natural traction induced by musculature following IFFs determines closed reduction on a fracture table is extremely difficult. To achieve anatomical reduction before intramedullary nail (IMN) fixation, we made an extended or a mini petrotrochantetic incision to facilitate temporary reduction using a pointed clamp. Subsequently, a curved and cannulated wire-passer was employed to pass through a multistrand cable to surround displaced fragments and strengthen intertrochanteric fixation. Afterward, a standard procedure was conducted to nail the fracture. We used the surgical technique in 9 young patients with an age range of 28~?48?years old. The fractures were categorized as AO/OTA 31-A2.2 (3 cases) and 31-A2.3 (6 cases). The injury-to-surgery interval was 2.5?days on average. Mean operation time was 55?min. All fractures achieved anatomical reduction and healed within 14?weeks postoperatively without cable breakage, implant irritation or deep infection. In conclusion, the surrounding technique with cerclage wire in IFFs in young adults is an effective surgical technique with easily achieved anatomical reduction to facilitate operative maneuvers and fracture healing.
