Ulnar dimelia: a rare case

C. Mathun Ram, G. Chidambaranathan


Mirror hand deformity or ulnar dimelia is a congenital anomaly and several papers presented in various journals. We received a patient a child of four years old with deformity of right upper limb. The child had fixed elbow of 10 and many fingers. Fingers were symmetrical to the midline axis and X-ray showed double ulna facing each other and Inner/medial ulna is longer than the lateral one. This is a rare entity and not reported till now in any literatures.
