What is MCP arthroplasty?

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.

What is PyroCarbon implant?

Durability + Biocompatibility. Page 2. PyroCarbon is a specific form of carbon that has been tailored for durability and biocompatibility. PyroCarbon exhibits favorable wear characteristics and fatigue endurance.

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.

Are finger joint replacements successful?

It usually results in a stable, pain-free and reasonably functional joint. The most serious complication is failure of the fused bones to grow together or properly align, which may require further surgery. Most people have good to excellent results. Mobility is one of the biggest failings of finger surgery.

Is Pyrocarbon a metal?

Pyrocarbon Material Pyrocarbon, a form of pyrolytic carbon, is a strong, ceramic-like material.

Why is Pyrocarbon used in prosthesis instead of graphite?

Pyrolytic carbon and other turbostratic carbons differ in that the layers are disordered, resulting in wrinkles or distortions within layers. This give pyrolytic carbon improved durability compared to graphite.

What is the recovery time for finger joint replacement?

Within about eight to 10 weeks, the majority of patients regain, on average, about two-thirds of the finger’s normal range of motion. By that point, patients are able to resume their usual activities.

What is MCP and PIP joint?

The interphalangeal joints of the hand are the hinge joints between the phalanges of the fingers that provide flexion towards the palm of the hand. The DIP, PIP and MCP joints of the hand: Distal InterPhalangeal. Proximal InterPhalangeal.

How long do finger joint replacements last?

The usual estimate: 10 to 15 years Rare complications requiring re-operation can occur soon after surgery; for others, a replaced joint can last two decades or more.

What kind of surgery is arthroplasty?

What is arthroplasty? Arthroplasty is a surgical procedure to restore the function of a joint. A joint can be restored by resurfacing the bones. An artificial joint (called a prosthesis) may also be used.

How long does a prosthetic finger last?

With proper care, a silicone prosthesis may last 3-5 years. Usually, creation of your prosthesis can begin three months after you are completely healed from amputation surgery and all swelling has subsided. You may need therapy to learn to use your new prosthesis.

How is Pyrocarbon made?

Pyrolytic carbon is man-made and is thought not to be found in nature. Generally it is produced by heating a hydrocarbon nearly to its decomposition temperature, and permitting the graphite to crystalize (pyrolysis).

What are finger joint replacements made of?

At present there are three types of joint replacements generally used. Rubber (silicone), metal/plastic and pyrocarbon (a material almost as hard as diamond). If you have isolated joint arthritis it will be most likely that one of the newer ‘surface replacements’ made from metal or pyrocarbon will be offered.

What happens after finger joint replacement surgery?

After surgery, you will work with a hand therapist to regain mobility and strength of the joint. Total recovery after finger joint replacement can take several months. Risks of finger joint replacement include infection, nerve injury, joint instability, and implant problems including wearing out and loosening.

Where is the MCP joint located?

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.

Where is the MCP joint?

The metacarpophalangeal joint (MCP joint), or knuckle, is where the finger bones meet the hand bones. At the MCP joint, the fingers can move in multiple directions. They can bend, straighten, spread apart and move together. MCP joints are important for both pinching and gripping.

How successful is hand surgery for arthritis?

Pros: Removing the entire trapezium eliminates the possibility of arthritis returning and, according to Dr. Ruch, LRTI has a 96 percent success rate. “Most patients achieve complete pain relief and mobility equal to that of a healthy thumb, with results lasting at least 15 to 20 years,” he says.
