Abstract：
BACKGROUND: Tibial shaft fractures are common injuries that can be treated with various methods, including interlocked intramedullary nail (IMN). However, there is limited data on the clinical outcomes of IMN for tibial shaft fractures in Yemen.
OBJECTIVE: To evaluate the clinical outcomes of primary IMN for tibial shaft fractures in Yemen.
METHODS: This was a prospective study of 134 patients who underwent primary IMN for tibial shaft fractures et al.-Thawra Modern General Hospital in Sana\'a, Yemen, between June 2016 and June 2020. The patients were between 18 and 70 years old, and the fractures were classified according to the AO classification system. The fractures were treated with IMN using a standard technique. The patients were followed up for a minimum of 2 years. The outcome measures included union time, complications, and functional scores.
RESULTS: The mean union time was 17 weeks. The overall complication rate was 18.7%. The most common complications were infection (8.2%), delayed union (6.7%), and nonunion (3.7%). The mean functional scores at the final follow-up were 91.4 for the Knee Society Score and 90.2 for the American Orthopaedic Foot and Ankle Society Score.
CONCLUSIONS: Primary IMN is an effective and reliable method for treating tibial shaft fractures in Yemen, with acceptable union time, complication rate, and functional outcomes.

摘要：
背景：胫骨干骨折是常见的损伤，可以用各种方法进行治疗，包括互锁髓内钉（IMN）。然而,也门IMN治疗胫骨干骨折的临床结局数据有限.
目的：评价也门地区原发性IMN治疗胫骨干骨折的临床疗效。
方法：这是一项前瞻性研究，纳入了134例因胫骨干骨折而接受原发性IMN的患者。-萨那现代综合医院，也门,2016年6月至2020年6月。患者年龄在18至70岁之间，根据AO分类系统对骨折进行分类。使用标准技术用IMN治疗骨折。对患者进行至少2年的随访。结果指标包括工会时间，并发症,和功能分数。
结果：平均愈合时间为17周。总并发症发生率为18.7%。最常见的并发症是感染（8.2%），延迟工会(6.7%)，和不愈合（3.7%）。最终随访时，膝关节协会评分的平均功能评分为91.4，美国骨科足踝协会评分为90.2。
结论：在也门，原发性IMN是治疗胫骨干骨折的有效和可靠的方法，在可接受的联合时间内，并发症发生率,和功能结果。
