Introduction

Because one-third of the tibia is subcutaneous throughout most of its length and its location, it is more prone to open fractures. Open distal tibia fractures are mostly due to RTA and sports injuries. The goal of treatment is to obtain a healed, well-aligned fracture; pain-free weight-bearing; and functional range of motion of the knee and ankle.

Materials and Methods

33 patients of the 18–60-year age group with open distal tibia extra-articular fractures (without vascular injury), less than 3 weeks old trauma were included in the prospective study for 1 year period (1st June 2019 to 31st May 2020). 17 cases were treated with the Hybrid external fixator (HEF) and 16 cases were treated with the Ilizarov fixator (IF).

Results

Significantly (P < 0.05), the mean duration of surgery was less in the HEF group (67.6 min), faster union of open type-II fractures in the HEF group (16.4 weeks), and also a higher AOFAS score at 6 months in open type-II fractures in the HEF group (84.4). There were two cases of equinus deformity in the IF group and one case of valgus deformity in the HEF group.

Conclusion

HEF and IF are both equally effective in the treatment of open distal tibia extra-articular fractures with the advantage of stable fracture fixation, early weight-bearing, preserving soft tissue, minimal periosteal stripping, and providing one-staged definitive intervention. However, HEF is preferred over IF in terms of less operating time, faster union, and a better functional outcome with minimal complications.

混合外固定器与 Ilizarov 主固定器治疗开放性胫骨远端关节外骨折的比较结果

介绍

由于三分之一的胫骨在其大部分长度和位置都位于皮下，因此更容易发生开放性骨折。开放性胫骨远端骨折主要是由于 RTA 和运动损伤。治疗的目标是获得愈合、排列良好的骨折；无痛负重；膝关节和踝关节的功能活动范围。

材料和方法

前瞻性研究纳入 33 名 18-60 岁年龄组开放性远端胫骨关节外骨折（无血管损伤）、创伤小于 3 周的患者，为期 1 年（2019 年 6 月 1 日至 2020 年 5 月 31 日） . 17例采用Hybrid外固定器（HEF）治疗，16例采用Ilizarov固定器（IF）治疗。

结果

显着（P  < 0.05），HEF组平均手术时间较短（67.6 min），HEF组开放性II型骨折愈合较快（16.4周），6个月时AOFAS评分较高。 HEF 组开放性 II 型骨折 (84.4)。IF组有2例马蹄足畸形，HEF组有1例外翻畸形。

结论

HEF 和​​ IF 在治疗开放性胫骨远端关节外骨折方面同样有效，具有骨折固定稳定、早期负重、保留软组织、最小化骨膜剥离和提供一期确定性干预的优点。然而，HEF 优于 IF，因为其手术时间更短、愈合更快、功能结果更好且并发症最少。
