Femur component for spacer of knee joint of patient, has tibia sided area comprising tibia sided surfaces for cooperating with tibia component of spacer, and clamping mechanism for clamping part of thigh bone

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention relates to a femur component for a knee joint spacer used in patients, particularly during temporary joint replacement or revision surgeries. The component is designed for attachment to the thigh bone (femur) and includes special surfaces to interact with the corresponding tibia component. It features a clamping mechanism for securing it to the thigh bone and has a coating containing antibacterial metals to reduce infection risk.

Use CasesContent extracted from patent full text and abstract with AI.

• Use as a temporary implant in knee revision surgeries to maintain joint space and proper alignment.
• Application in prosthetic joint replacement procedures where infection management is critical.
• Utilization in orthopedic surgeries requiring temporary stabilization of the knee after removal of an infected or damaged prosthesis.

BenefitsContent extracted from patent full text and abstract with AI.

• Improved infection control owing to the antibacterial metal coating.
• Enhanced fixation and stability through a dedicated clamping mechanism.
• Durable construction using biocompatible metals such as titanium or cobalt-chromium alloys.
• Facilitates better cooperation with tibial spacer components, improving patient outcomes during healing or revision periods.

Patent Abstract

The femur component (1) has a femur sided area comprising femur sided surfaces (5, 6) for retaining a thigh bone, where the femur component is made of metal e.g. surgical steel, titanium, titanium alloy or cobalt chromium alloy. A rounded tibia sided area comprises tibia sided surfaces (7-9) for cooperating with a tibia component of a knee joint spacer. A clamping mechanism (10) clamps a part of the thigh bone. A coating i.e. titanium oxide coating, in which antibacterial metals e.g. copper, silver and zinc, and metallic salts are homogeneously distributed is formed on the femur component.
