What is MCP arthroplasty?

Metacarpophalangeal joint arthroplasty is a procedure performed to treat rheumatoid arthritis of the MCP joints. Also known as joint replacement, arthroplasty involves removing the damaged joints and tissue, and replacing them with synthetic materials or artificial implants.

How long does MCP joint replacement last?

A retrospective study of patients who underwent metacarpophalangeal joint replacement with silastic implants and were followed up to 17 years found a 63% success rate with the procedure. Two-thirds of the implants fractured by 15 years’ postop.

What is PIP arthroplasty?

Proximal interphalangeal (PIP) joint arthroplasty remains an established surgical treatment option for the arthritic and painful PIP joint. A variety of materials have been used for arthroplasty including silicone, metal-plastic, and pyrolytic carbon. In addition, constrained and semiconstrained designs have been used.

What does MP joint stand for?

The large joints in the hand at the base of each finger are known as the metacarpophalangeal (MP, or MCP) joints. They act as complex hinge joints and are important for both power grip and pinch activities.

What happens after finger joint replacement?

What Is Recovery Like after Finger Joint Replacement Surgery? Some patients begin rehabilitation one to two days after surgery, but others may need more time. A splint is generally worn for four to five weeks after the procedure in order to keep the joint stable and aid in the healing and strengthening of soft tissues.

Why does my metacarpophalangeal joint hurt?

How successful is PIP joint replacement?

Long-term survivorship, 8–10 years, of silicone implants in the PIP joint have been reported between 80–90%.

Are MCP and MP joints the same?

The metacarpophalangeal joint or MP joint, also known as the first knuckle, is the large joint in the hand where the finger bones meet the hand bones. The MCP joint acts as a hinge joint and is vital during gripping and pinching. When arthritis affects the MP joint, the condition is called MP joint arthritis.

What type of joint is MCP?

The metacarpophalangeal (MCP) joints are diarthrodial joints where the large convex heads of the distal aspect of the metacarpals articulate with the concave-shaped proximal aspect of each phalange. The articulating surface of each metacarpal head and proximal phalange is composed of hyaline cartilage.
