Rendezvous Surgery for Peri-Implant Fractures around Locking Compression Plate on Anterolateral Bowed Femur: A Case Report

An 84-year-old female visited with an intertrochanteric femoral fracture. The patient had undergone an open reduction and internal fixation with a compressive plate and elastic nail in an ipsilateral atypical diaphyseal femoral fracture in the past. Compressive plate and elastic nail remained, and anterolateral bowing was presented. To treat the periprosthetic trochanteric fracture, a proximal femoral nail was used without removing the previously inserted compressive plate. Under the “rendezvous” technique, using a combination of fixating intramedullary nail and compressive plate simultaneously, the distal screw was fixed, and a femoral head lag screw was inserted after reducing the fracture. Complete union of the fracture was achieved 16 months after the operation, and a decrease in mobility function was not found postoperatively. The authors report this case for the “rendezvous” technique as a treat ment option for elderly patients with periprosthetic trochanteric fractures, who had previously undergone surgical treatment for ipsilateral atypical diaphyseal femoral fractures with anterolateral bowing.
