Sixty-one cases of fracture or dislocation were treated with France-made biopolyester ligament. They consisted of 18 cases of fracture of patella, 13 cases of fracture of olecranon, 8 cases of fracture of distal clavicle, 10 cases of dislocation of acromino-clavicular joint, 6 cases of separation of lower tibio-fibular joint, 3 cases of rapture of cruciate ligament and 3 cases of fracture of upper third of ulna with dislolcation of radial head. The follow-up period lasted from 3 to 12 months with an average of 7.3 months. The result showed that of the 56 follow-up cases, 49 were excellent and 7 were satisfactory. There was no redisplacement occured in this group. The Biopolyester ligament was believed to be a good and safe material for fractures or dislocations and was of good strength of extension and easy to use.
