Subluxation of the Carpometacarpal Joint: Symptoms, Diagnosis, and Treatment
Subluxation of the carpometacarpal joint of the hand refers to the partial dislocation or misalignment of the joint connecting the wrist to the base of the thumb. This condition commonly occurs due to trauma or repetitive stress on the joint, leading to the bones in the hand being out of their normal position. Symptoms of this condition include pain, swelling, limited range of motion, and weakness in the hand and thumb. Subluxation can also result in instability and difficulty with gripping or performing fine motor tasks. Diagnosis is typically made through a physical examination, medical history review, and possibly imaging tests. Treatment options include conservative measures like rest, immobilization, and physical therapy, as well as surgical intervention in severe cases. Early diagnosis and appropriate management can help alleviate symptoms and restore normal hand function.
