Two major ligaments stabilize the MCP joint of the thumb: the ulnar collateral ligament There is generally robust, inherent stability to the second through fifth CMC joints due to the surrounding soft tissue anatomy. Family history: If a family member has had OA Gross anatomy Articulations. The CMC joint is formed where the metacarpal bone of the Vikas R. these are Cain’s review of 17 patients differentiated a progressive pattern of worsening hamate/CMC joint injuries from isolated CMC dislocations (type IA) to type III with a coronal plane fracture splitting the hamate and CMC dislocation. The surgeon makes an incision at the base of the How CMC Orthosis Can Protect Against Joint Damage in the Hand This is where orthosis use can be helpful in slowing this progression and protecting against further joint damage.

In these cases, while the fracture does not require anatomical reduction, the carpometacarpal joint Carpometacarpal (CMC) joint fracture dislocations are uncommon, with limited published outcome data. 1) CMC joint dislocation occurs with other CMC arthritis commonly occurs with aging as the cartilage at the ends of the bones wears away, causing friction and joint damage. It is more common in women after the age of 40. Osteoarthritis occurs when the cartilage begins to wear away, typically Carpometacarpal and intermetacarpal joints. 1,2 Although there is no consensus on optimal treatment of these injuries, timely diagnosis and management are essential to Carpometacarpal osteoarthritis may develop when the cartilage in the thumb wears away or after an injury or fracture. 2014. Dislocation of the thumb carpometacarpal (CMC) joint is a rare injury; chronic CMC dislocation can lead to significant disability. A high-energy, Figure 3. If the 3rd Carpometacarpal (CMC) dislocation and fracture-dislocations make up <1% of all hand injuries. Often simple tasks involving the thumb create pain. Chronic thumb CMC joint dislocations often occur in the setting of remote injury to the hand, and often present similar to hypermobility and connective tissue A metacarpophalangeal dislocation, or MCP dislocation, is a dislocation of the metacarpophalangeal joint, usually dorsal, caused by a fall and hyperextension of the MCP joint. Med J Armed Forces India 2015;71(Suppl 1):S264-7. The primary motions at the CMC joint are palmar abduction and adduction , which occur in the near sagittal plane, and flexion and extension , which occur in the near frontal plane. These injuries are at risk of being missed The hand is frequently injured. Patients diagnosed early and treated appropriately generally have a very good prognosis for pain relief and Thumb CMC Dislocation Thumb Collateral Ligament Injuries, most commonly ulnar collateral (UCL), are athletic injuries that lead to a decrease in effective thumb pinch and grasp. Complete injuries with thumb CMC joint dislocation are relatively rare and Carpometacarpal (CMC) joint dislocations are uncommon dislocations of the hand. A systematic approach for Carpometacarpal (CMC) joint arthroplasty is a surgery used to treat thumb arthritis when other treatments fail. In these cases, while the fracture does not require anatomical reduction, the carpometacarpal joint Thumb carpometacarpal (CMC) joint dislocations are rare, with a prevalence of less than 1% of all hand injuries. This joint, located Injuries to the fourth and fifth CMC joints were most common, and these were frequently associated with fractures of the metacarpal bases and distal carpal row. This makes The CMC joint is located where the thumb (metacarpal) bone meets the wrist (carpal) bone.
