Fig. 5. For early stages of ulnar drift hand deformity, the following procedures aim to restore the normal position of the fingers. Through a square bracket-shaped incision at dorsal capsule of the metacarpophalangeal joint (A), a thorough synovectomy of the joint is performed (B), followed by plication of the capsule (C). (D) The subluxated extensor tendon is divided longitudinally on the radial side of sagittal band, relocated to the normal site, and plicated. (E) The intrinsic tendons at ulnar side are detached and transferred to the radial side of the next finger, thus changing a deforming force into a correcting force (Drawings are authors’ own artwork).
