Abstract
Purpose
: The metacarpal fractures have been treated by conservative or operative methods. Percutaneous intramedullary multiple Kirschner-wire fixation can achieve accurate reduction and prevent angular or rotational deformity which could occur with single pin fixation. Materials and Method : Twenty four cases in 19 patients of metacarpal fractures were treated by ercutaneous intramedullary multiple Kirschner wire fixation technique. All 24 cases had at least 1 year follow-up period. In 90 degree flexion of the metacarpophalangeal(MP) joint, two or more pins were inserted into the periphery of the metacarpal head in slight volar side. After the pins passed the fracture site under the C-arm image intensifier control, the wrist was fully flexed so that the pins emerged on the dorsum of the wrist. Then, the distal ends of the pins were embeded in the metacarpal head. Results : The level of the metacarpal fractures were 8 cases at the neck, 14 cases at the shaft and 2 cases at the base. In 22 cases, two pins were used and three pins were used in 2 cases. The average bone union period was 5 weeks and 3 days with removal of pins at 6 weeks in average. The average angulation was below 3 degree and none of the metacarpal showed clinical rotational deformity. All cases had normal range of motion of the MP joint. Conclusion : Percutaneous intramedullary multiple Kirschner-wire fixation can achieve accurate reduction and firm fixation, and permit early exercise of the MP joint. So, this technique can be one of the useful methods for the metacarpal fractures.
