该研究是一项回顾性评价和比较。对75例老年（>50岁）AO B2型踝关节骨折患者进行切开复位内固定治疗。所有患者均接受至少12个月的回顾性随访。根据治疗方法，75 名患者被分为两组。 Knowles pin (KP) 组包括 45 名患者，平均年龄 62.7 岁。管状钢板（TP）组包括30例患者，平均年龄60.0岁。比较两组的临床结果。两组在损伤机制、骨折模式、开放性骨折分级、复合医疗状况和踝关节评分方面相似（所有 P 值 < 0.28）。然而，与TP组相比，KP组的伤口切口更小，手术时间更短，住院时间更短，哌替啶使用更少，对症硬件更少，并发症发生率更低（所有P值<0.03）。综上所述，老年AO-B2型踝关节骨折采用Knowles针侧向固定，简单、有效、并发症发生率低，值得推荐。
The study was a retrospective evaluation and comparison. Seventy-five elderly patients (> 50 years) with AO type-B2 ankle fractures were treated by open reduction and internal fixation. All patients were followed up retrospectively for at least 12 months. The 75 patients were divided into two groups, based on the method of treatment. The Knowles pin (KP) group included 45 patients with an average age of 62.7 years. The tubular plate (TP) group included 30 patients with an average age of 60.0 years. The clinical results were compared between the two groups. Both of the groups were similar in respect to the injury mechanisms, fracture pattern, open fracture grade, compounding medical conditions, and ankle score (all P values < 0.28). However, the KP group had significantly smaller wound incisions, shorter surgery time, shorter hospital stay, less meperidine use, less symptomatic hardware, and lower complication rates than the TP group (all P values < 0.03). In conclusion, lateral fixation of AO type-B2 ankle fractures in the elderly by the Knowles pin is recommended due to its simplicity, efficacy and low complication rate.
