flexion finger deformity correction

The malformation features are: 1. The flexion deformity often occurs in the little finger, occasionally involving the ring finger, and more than half is bilateral. 2. Buckling often occurs in the proximal interphalangeal joint, accompanied by metacarpophalangeal joints or wrist-facing extensional extension. 3. Before the age of 10, the flexion of the fingers occurred progressively, often with a family history, which was not obvious at first, and gradually increased and was emphasized by the parents. 4. Often accompanied by other systemic syndromes such as doun syndrome, klinefelfer syndrome, several common facial syndromes, accompanied by skew deformity. 5. The main manifestation is the shortening of the flexor digitorum, the cause of the deformity is unclear, mostly due to the irregular origin of the superficial muscle, which can be caused by the flexor digitorum or the sacral muscle. Often accompanied by skin shortening, the finger extension function will also be limited. Treating diseases: refers to deformed multi-finger malformations Indication Severe deformity. Preoperative preparation Regular skin preparation to prevent postoperative infection. Surgical procedure Feasible z-formation, patch implantation, flexor digitorum tendon and joint capsule lysis. The commonly used flexor digitorum tendonectomy is now introduced. A transverse incision is made along the transverse line at the distal end of the ring finger and the palm of the little finger to reveal the trochlear, and the flexor digitorum tendon of the abnormal little finger is revealed. The sputum is separated and cut, and the little finger is straightened. Postoperative functional exercises. If there is a soft tissue defect, z-formation, skin grafting, etc.
