A palmar fascia release is a surgical procedure that involves removing some or all of the fascia on the palm of the hand, located below the outer layer of skin. Physicians perform this surgery to treat Dupuytren's contracture which is a hand deformity that occurs when abnormal tissue forms in the fascia under the palm. That fascia is connective tissue that holds the skin of the palm in place. The way this condition affects that tissue leaves most patients with the loss of normal hand function.
