Bilateral Uncemented Hemiarthroplasty in a Patient with Bilateral Lower limb PPRP with Right Knee Arthrodesis: Surgical Difficulties and Techniques

Abstract

Introduction: Standard references such as knee and lower leg position cannot be used in patients with knee arthrodesis with a bilateral neck of femur fracture during bipolar hemiarthroplasty. We describe a simple technique that guides a surgeon in assessing the femoral stem version in such cases. Case report: We present a case of 52 years old male with bilateral lower limb Post Polio Residual Paralysis with right knee arthrodesis who sustained bilateral neck of femur fractures. The difficulties, in this case, were the inability to flex the knee and to use the ankle or the opposite limb and its bony landmarks as reference. Conclusion: We describe a simple surgical technique of inserting a Steinmann pin in the distal femur in the coronal plane parallel to the transcondylar axis for intraoperative assessment of neutral position and version of the femoral stem. Keywords: Bilateral; hemiarthroplasty; femoral stem; anteversion; knee arthrodesis.
