Clayton Brown - Shoulder, Elbow, Hand & Wrist Surgeon
This condition occurs when there is abnormal thickening of the deep tissue between the palm of your hand and your fingers. This thickening occurs very gradually and will start to make your fingers curl toward your palm.
If this condition gets to the stage where it significantly limits your hand function, surgery may be recommended. This usually involves removal of the thickened tissue, allowing you to straighten your fingers again.
