| Popis: | Purpose This study aimed to evaluate the effect of distal blocking screws on the stability and healing of ulnar diaphyseal fractures treated with intramedullary (IM) nails. The primary research question was whether the addition of distal blocking screws enhanced fracture stabilization and promoted faster healing than the standard IM nailing techniques. Methods This retrospective study reviewed medical records of 30 patients with ulnar diaphyseal fractures treated from February 2018 to September 2023. The patients were divided into two groups: those treated using IM nails alone ( n = 17) and those treated with using IM nails with distal blocking screws ( n = 13). The surgical time, medullary canal space, fracture healing time, and complications were assessed. Functional outcomes were evaluated using the Grace and Eversmann rating system, the DASH scores, and the VAS scores. Results The addition of distal blocking screws resulted in a slightly longer surgical time (56 min vs 47 min). However, the group with distal blocking screws had smaller medullary canal space and showed significantly faster fracture healing times (2.3 months vs 3.9 months; p = .036). There were no reported complications of nonunion, nerve injury, or infection in the distal blocking screw group, whereas the IM nail-only group had one case of nonunion (5.7%). Conclusion The use of distal blocking screws in conjunction with IM nails for ulnar diaphyseal fractures improves fracture stability and promotes faster healing. |
