Basal Thumb Arthritis
Overview
Basal thumb arthritis, also known as carpometacarpal (CMC) arthritis, is a degenerative joint disease that affects the joint at the base of the thumb. This joint, called the CMC joint, allows for the thumb’s wide range of motion and is prone to wear and tear over time, leading to arthritis. Basal thumb arthritis is a common condition, particularly in women over the age of 50.
Procedure
The treatment for basal thumb arthritis typically involves the following steps:
Diagnosis: The doctor will evaluate the patient’s symptoms and perform physical examinations, such as the grind test and the pinch grip test, to confirm the diagnosis of basal thumb arthritis.
Conservative Treatment: The initial treatment for basal thumb arthritis is usually conservative, which may include rest, splinting, exercises, medications, or corticosteroid injections to relieve pain and inflammation.
Surgery: If conservative treatment does not provide relief, or if the condition is severe, surgery may be necessary. The surgery for basal thumb arthritis may involve one of several procedures, depending on the cause and severity of the condition. These may include:
- Ligament reconstruction: This procedure involves using a tendon graft to reconstruct the ligaments that support the CMC joint and stabilize the thumb.
- Joint fusion: This procedure involves removing the damaged joint surfaces and fusing the bones together with screws or plates to provide stability and relieve pain.
- Joint replacement: This procedure involves replacing the damaged joint surfaces with a prosthetic joint to restore mobility and reduce pain.
- Recovery: After the surgery, the patient will need to follow specific post-operative instructions, such as wearing a splint and performing exercises, to promote proper healing and restore strength and function to the thumb.
In summary, basal thumb arthritis is a degenerative joint disease that affects the joint at the base of the thumb. The initial treatment is usually conservative, but surgery may be necessary if symptoms persist. The surgical procedures for basal thumb arthritis involve ligament reconstruction, joint fusion, or joint replacement. Patients will need to follow specific post-operative instructions to promote proper healing and restore strength and function to the thumb.
