Abstract

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.

成人前臂骨骺骨折尺桡侧髓内钉固定中的远端阻断螺钉增量。
目的:本研究旨在评估远端阻断螺钉对使用髓内钉(IM)治疗尺骨骺端骨折的稳定性和愈合的影响。主要研究问题是,与标准 IM 钉技术相比,加用远端阻断螺钉是否能增强骨折的稳定性并加快愈合:这项回顾性研究回顾了2018年2月至2023年9月期间接受治疗的30名尺桡骨骨骺骨折患者的病历。患者分为两组:单纯使用 IM 钉治疗的患者(n = 17)和使用 IM 钉加远端阻断螺钉治疗的患者(n = 13)。对手术时间、髓腔间隙、骨折愈合时间和并发症进行了评估。使用格雷斯和埃弗斯曼评分系统、DASH评分和VAS评分对功能结果进行评估:结果:增加远端阻断螺钉导致手术时间略有延长(56 分钟 vs 47 分钟)。然而,使用远端阻断螺钉的一组患者髓管间隙更小,骨折愈合时间明显更快(2.3 个月 vs 3.9 个月;p = 0.036)。远端阻断螺钉组未出现骨折不愈合、神经损伤或感染等并发症,而仅使用 IM 钉组出现一例骨折不愈合(5.7%):结论:在治疗尺骨骺端骨折时使用远端阻断螺钉和 IM 钉可提高骨折的稳定性并加快愈合。

期刊介绍: Journal of Orthopaedic Surgery is an open access peer-reviewed journal publishing original reviews and research articles on all aspects of orthopaedic surgery. It is the official journal of the Asia Pacific Orthopaedic Association. The journal welcomes and will publish materials of a diverse nature, from basic science research to clinical trials and surgical techniques. The journal encourages contributions from all parts of the world, but special emphasis is given to research of particular relevance to the Asia Pacific region.
