Custom-Made Cement-Linked Distal Femoral Replacement for Interprosthetic Femur Fractures: Five-Year Follow-Up.

Interprosthetic femur fractures between total hip and total knee replacements are challenging injuries with rising incidence. Stability of the either implants, quality, and quantity of remaining bone as well as patients' comorbidities play an important role in operative management. Open reduction and internal fixation, advanced revision arthroplasty techniques, and megaprostheses are available options. In more complex cases, custom-made implants maybe necessary to achieve immediate weight-bearing and restore function.
