Read on to learn everything you need to know about CMC arthroplasty, including benefits, risks, and what to expect during the procedure. However, CMC arthroplasty generally involves more risk and is more expensive than a trapeziectomy. People who have CMC arthroplasty are generally very satisfied with the results, and it’s less invasive than surgical options that involve tendon grafts. During CMC arthroplasty, the removed bone is replaced with an artificial implant.ĬMC arthroplasty has been found to be up to 93% successful at 10-year follow-ups for new-generation implants. The trapezium is a small bone, measuring less than an inch in greatest diameter. ![]() Your surgeon will discuss with you which option is best for your fracture.Carpal metacarpal arthroplasty, commonly called CMC arthroplasty, is a type of joint replacement surgery, an alternative to the traditional gold standard surgical treatment for carpometacarpal (CMC) arthritis, called trapeziectomy.ĭuring a trapeziectomy, a surgeon removes the bone at the base of your wrist called the trapezium. There are pros and cons to all treatment options. ![]() External fixation techniques include the use of pins in bone that are held in place through their attachment to an external fixation device.Internal fixation techniques include the use of wires, pins, plates, and screws.These broken bone fragments must be held in place while the bone heals.īone fixation techniques include devices that hold the bone fragments in place either inside the body (internal fixation) or outside the body (external fixation). Your surgeon may use one of several operative fixation techniques to realign the bone fragments. You may need surgery to treat the thumb fracture, depending on the location of the break, the alignment of the broken bone, and the amount of movement between the fragments. During that time, you will need regular X-rays to ensure that the bone has not slipped out of alignment. You will likely need to wear the cast for at least 4 to 6 weeks. If the bone fragments of the fracture have not moved (displaced) very much, or if the break is located in the middle (shaft) of the bone, your surgeon may be able to treat the thumb fracture without surgery using a specially designed cast (spica cast) to hold the bone fragments in place. These injuries function as ligament injuries and are often treated as such. These are often avulsion injuries, which occur during an extreme force to the joint that causes the ligament to rip away from its attachment, taking a piece of bone with it. Sometimes, thumb fractures can result in joint instability when they involve the important ligaments that keep the joints aligned. Like the metacarpal, the distal and proximal phalanges can fracture near/into a joint or in the shaft of the bone. The other bones of the thumb - the distal phalanx and proximal phalanx - are also susceptible to fractures. These are often easier to treat than fractures involving the joint. A Rolando fracture is similar to a Bennett fracture, except that instead of a clean break, the bone is shattered into several pieces.įractures of the thumb metacarpal can also occur in the long portion of the bone, which is called the metacarpal shaft.A Bennett fracture is a fracture at the base of the thumb metacarpal involving the CMC joint, resulting in a clean break with a sizeable piece of bone broken off.The most common of these in the thumb are fractures involving the base of the first metacarpal, affecting the CMC joint where the thumb connects to the wrist: Fractures that involve the joints are typically more difficult to treat and are at increased risk for an unfavorable outcome. Typically, the most concerning and problematic broken bones involve the joints. All of the bones in the thumb are susceptible to fracture. ![]()
