Abstract

Purpose: To present our operative experiences in uncommon dislocation of the extensor tendons at the level of metacarpophalangeal joint Materials and Methods: Eight cases which were followed up for an average 11.6 months (range, 6 to 24 months) were reviewed. The causes were traumatic dislocation in 5 cases, spontaneous dislocation in 2 cases and dislocation in rheumatoid arthritis in 1 case. The location was index finger in 1 case, long finger in 3 cases, ring finger in 1 case, little finger in 3 cases. Six cases were dislocated to ulnar side and 2 cases to radial side. Result: All cases were operated; repair of intertendinous fascia in 1 case, repair of sagittal band in 2 cases, repair of sagittal band with intertendinous connection transfer in 2 cases, plication procedure in 2 cases and loop procedure in 1 case. Recurrent dislocation was not found except 1 case that did not have enough immobilization. Conclusion: Good results were made from operative treatment of dislocation of the extensor tendons at the level of metacarpophalangeal joint.
