The purpose of this study was to assess the clinical outcomes and complications associated with intramedullary and transverse K-wire fixations of 5th metacarpal neck fractures.
Patients who were operated for 5th metacarpal neck fractures between 2019 and 2022 were evaluated retrospectively. Regarding the surgical treatment methods, patients were assessed by dividing them into two groups. The first group comprised patients who underwent treatment with an intramedullary K-wire. The second group comprises patients who underwent transverse K-wire fixation.
The average quick DASH score of all patients was 5.6±4.7 in the intramedullary K-wire fixation group and 5.9±5.1 in the transverse K-wire fixation group. An average 5th finger metacarpophalangeal joint extension limitation was 6.2±5.7° in the intramedullary fixation group and 6.1±5.8° in the transverse K-wire group. The mean radiological union time was 4.9±0.7 weeks in the intramedullary fixation group and 5.1±0.7 weeks in the transverse K-wire group. No statistically significant difference was found between the quick DASH scores and degrees of the MCP joint extension limitation ( p=0.785). Intramedullary fixation and transverse K-wire fixations are effective surgical treatment methods for metacarpal neck fractures.
It has been reported that the intramedullary fixation method in metacarpal bone fractures is more effective than the fixation methods with cross and transverse K-wire. But our results revealed no difference in clinical outcomes between the two surgical fixation methods.
We observed no statistically significant difference between the two fixation techniques with regard to union, clinical outcomes, or complications.

本研究旨在评估髓内和横向 K 型钉固定第五掌骨颈骨折的临床结果和并发症。
回顾性评估了 2019 年至 2022 年间接受第五掌骨颈骨折手术的患者。根据手术治疗方法，将患者分为两组。第一组患者接受髓内 K 型钉治疗。第二组患者接受横向 K 型钉固定。
髓内 K 型钉固定组所有患者的平均快速 DASH 评分为 5.6±4.7，横向 K 型钉固定组为 5.9±5.1。髓内固定组第五指掌指关节伸展受限平均为 6.2±5.7°，横向 K 型钉组为 6.1±5.8°。髓内固定组的平均影像学愈合时间为 4.9±0.7 周，横向 K 型钉组为 5.1±0.7 周。快速 DASH 评分和 MCP 关节伸展受限程度之间无统计学差异（p=0.785）。髓内固定和横向 K 型钉固定都是治疗掌骨颈骨折的有效手术方法。
据报道，髓内固定法治疗掌骨骨折比交叉和横向 K 型钉固定法更有效。但我们的结果显示，两种手术固定方法的临床结果无差异。
我们观察到两种固定技术在愈合、临床结果或并发症方面没有统计学差异。
髓内固定；掌骨颈骨折；横向 K 型钉固定。
