Tibial lengthening with a motorized magnetic intramedullary nail after combined plating and titanium mesh cage for distal femur periprosthetic fracture nonunion

Abstract

Fifty-seven years old female presented with resistant nonunion and limb length discrepancy (LLD) following distal periprosthetic fracture. The report described the experiences treating these conditions and literature review about the topic. Nonunion in periprosthetic distal femoral fractures can be challenging to the orthopedic surgeon and can result in a significant LLD. With the patient described herein, a combined technique with plating and titanium mesh cage and subsequent tibial lengthening with a motorized lengthening nail was used to address these conditions.
