2.3. Surgical Technique
fracture
The KP method involved the insertion of two K-wires across the fracture site to stabilize the fracture. The number and size of K-wires used were determined based on the surgeon’s preference and the specific characteristics of the fracture (The IP method involved the insertion of an intramedullary nail in the anterograde direction. The entry point was selected at the base of the ulnar dorsal border of the metacarpal using a needle under imaging guidance. A small hole was made with a drill, into which the operator inserted the nail. The fracture was reduced via maneuver, and the nail passed across the fracture part (The combined method involved the placement of an intramedullary pin followed by parallel K-wire fixation. Initially, an intramedullary nail was inserted into the metacarpal bone to stabilize the fracture, typically through the base. Following intramedullary pinning, K-wires were placed across the distal part of the intramedullary nail, and the pin was inserted halfway through the dorsal aspect of the nail, touching the nail and making an additional accurate reduction possible. Another pin was inserted on the volar aspect of the nail (All three methods involved postoperative immobilization using a splint for 4 weeks. We encouraged patients to practice ROM after taking off splints. The pins were removed after 6 weeks, postoperatively.
