The ability to bend the fingers is governed by supportive tendons that connect muscles to the bones of the fingers. The tendons run along the length of the bone and are kept in place at intervals by tunnels of ligaments called pulleys.
Dupuytren’s Contracture is a hand condition where thickening of the underlying fibrous tissues of the palm cause the fingers to bend inward. Patients with this condition are unable to fully straighten the affected fingers.
The muscles and bones of the hand are connected by thick flexible tissue called tendons. Tendons are covered by a thin soft sheath of tissue known as synovium. Extensor pollicis brevis and abductor pollicis longus are two tendons located on the thumb side of the wrist.
