Significant bone loss requiring extensive reconstruction around the hip and knee is often required following the treatment of malignant bone tumors, aggressive benign bone tumors, infection, multiple revised and failed joint replacements and massive trauma, particularly in the elderly osteoporotic patient. Limb-preserving techniques, using modular segmental endoprostheses, provide a functional reconstruction for these patients. Due to unpredictable and difficult conditions encountered with the remaining bone, muscle and soft tissues, the prosthetic construct must perform under severe conditions. DePuy Synthes Joint Reconstruction Revision Solutions offers both surgeons and patients a comprehensive portfolio of products for managing the many challenges of total joint arthroplasty. The DePuy Synthes Joint Reconstruction LPS (Limb Preservation System) is designed with these considerations in mind to allow for versatility in such difficult reconstructions.
