ABSTRACT
Objective To evaluate the effects of immobilization of flexor tendon with elastic rubber band after the repair in 58 cases with flexor tendon completely severed in Zone Ⅱ . Methods The severed flexor tendon was repaired with the modified Kessler method. The rubber band was linked to the end of the nail with silk thread. The forearm and hand joint were immobilized by dorsal plaster cast.The rubber band was fixed with short tube plaster at the lower part of forearm so as to keep the interphalangeal joints in flexion. 48 hours post operation, exercises were done to extend fingers initiatively and flex fingers passively with the help of the elastic rubber band. The practice lasted for 3 weeks. Results The patients were followed up for three to six months.The digital functions of flexion and extension were normal. Conclusion Using elastic rubber band to immobilize flexor tendon post operation proves to have a remarkable effect on the functional recovery.
