Plate fixation is an established method for treating unstable distal clavicle fractures. However, the appropriate timing of surgery for acute distal clavicle fractures remains unclear. The present study aimed to evaluate the clinical outcomes of osteosynthesis using a Scorpion plate and to assess the influence of surgery timing on the surgical outcomes for acute unstable distal clavicle fractures. We retrospectively reviewed 105 patients who underwent fixation for acute unstable distal clavicle fractures (Neer type II and V) using the Scorpion plate between 2008 and 2018. Patients were divided into early (45 patients) and delayed (60 patients) treatment groups based on the timing of the surgical intervention (within or after 7 days). The outcomes were postoperative complications (nonunion, peri-implant fracture, plate loosening, plate-related pain, and stiffness). We evaluated the outcomes from X-ray radiographs and clinical notes. Among the 105 patients, nonunion, plate loosening, plate-related pain, and stiffness were observed in six patients (5.7%), four patients (3.8%), seven patients (6.7%), and one patient (1.0%), respectively. The nonunion rate was significantly higher in the delayed treatment group than that in the early treatment group (P = 0.036). Although the difference was not significant, plate loosening and stiffness were only observed in the delayed treatment group. Our results demonstrated that osteosynthesis using Scorpion plates achieved satisfactory surgical outcomes for unstable distal clavicle fractures. In addition, this study suggested that performing surgery within 6 days after injury is recommended to reduce postoperative complications.

Scorpion钢板治疗锁骨远端骨折及其时机对手术效果的影响：一项回顾性队列研究，共105例

钢板固定术是治疗不稳定的远端锁骨​​远端骨折的既定方法。但是，急性锁骨远端骨折的手术时机尚不清楚。本研究旨在评估使用Scorpion钢板进行骨合成的临床疗效，并评估手术时机对急性不稳定的锁骨远端骨折的手术效果的影响。我们回顾性分析了2008年至2018年间使用Scorpion钢板对105例因急性不稳定的远端锁骨​​远端骨折（Neer II型和V型）进行固定的患者。根据患者的不同，患者分为早期（45例）和延迟（60例）治疗组手术干预的时间（7天之内或之后）。结果是术后并发症（骨不连，种植体周围骨折，钢板松动，钢板相关疼痛，和刚度）。我们评估了X光片和临床记录的结果。在105例患者中，分别观察到6例（5.7％），4例（3.8％），7例（6.7％）和1例（1.0％）的骨不连，钢板松动，与钢板相关的疼痛和僵硬。 。延迟治疗组的骨不连率明显高于早期治疗组（P = 0.036）。尽管差异不明显，但仅在延迟治疗组中观察到钢板松动和僵硬。我们的结果表明，使用Scorpion钢板进行骨固定对于不稳定的锁骨远端骨折可达到令人满意的手术效果。此外，这项研究建议建议在受伤后6天内进行手术以减少术后并发症。我们评估了X光片和临床记录的结果。在105例患者中，分别观察到6例（5.7％），4例（3.8％），7例（6.7％）和1例（1.0％）的骨不连，钢板松动，与钢板相关的疼痛和僵硬。 。延迟治疗组的骨不连率明显高于早期治疗组（P = 0.036）。尽管差异不明显，但仅在延迟治疗组中观察到钢板松动和僵硬。我们的结果表明，使用Scorpion板进行骨固定对于不稳定的锁骨远端骨折可达到令人满意的手术效果。此外，这项研究建议建议在受伤后6天内进行手术以减少术后并发症。我们评估了X光片和临床记录的结果。在105例患者中，分别观察到6例（5.7％），4例（3.8％），7例（6.7％）和1例（1.0％）的骨不连，钢板松动，与钢板相关的疼痛和僵硬。 。延迟治疗组的骨不连率明显高于早期治疗组（P = 0.036）。尽管差异不明显，但仅在延迟治疗组中观察到钢板松动和僵硬。我们的结果表明，使用Scorpion板进行骨固定对于不稳定的锁骨远端骨折可达到令人满意的手术效果。此外，这项研究建议建议在受伤后6天内进行手术以减少术后并发症。
