Abstract: Objective This study aimed to explore the therapeutic effect of internal fixation with high strength suture, anchors and locking plate on greater tuberosity fracture, and provided a safer and more effective treatment. Methods A total of 40 patients diagnosed with greater tuberosity fracture in the Department of Orthopedics of Jieyang People's Hospital, Guangdong Province,were included from September 2016 to June 2024. They were divided into the locking plate fixation group and combined group with high strength suture, anchors and locking plate randomly. Statistical analysis will be conducted to compare the baseline data, preoperative, postoperative, and 3-month follow-up clinical indicators between the two groups. Results All patients in this study were followed up, and there was no statistically significant difference in preoperative data between the two groups P>0.05. Compared with the locking plate fixation group, the combined group had a smaller displacement distance, a greater range of motion on shoulder （P<0.05）. The Constant-Murley score in the combined group was higher during the 3-month follow-up, and there were fewer post-operative complications （P<0.05）. Conclusion Compared with the locking plate fixation, the combined group has more satisfactory clinical efficacy, with faster postoperative recovery, less impact on shoulder motions, and fewer post-operative complications.

摘要： 目的 本研究将探索大结节锁定板联合高强线、肌腱韧带固定锚钉固定组对肱骨大结节骨折的治疗效果,为此类骨折提供更安全且有效的治疗方案。方法 纳入自2016年09月至2024年06月期间于揭阳市人民医院就诊的40名诊断为肱骨大结节骨折的患者,根据手术方式的不同将其分为单纯钢板固定组（钢板组）和钢板联合高强线、肌腱韧带固定锚钉固定组（锚板组）,统计分析比较两组之间基线资料、术前、术后及术后3月随访的临床相应指标是否具有统计学差异。结果 该研究40例患者均获得随访,两组术前的资料（年龄、性别、BMI、基础病）等指标无统计学差异（P>0.05）;与钢板组比较,锚板组术后大结节移位距离更小,前屈上举活动度及体侧外旋活动度更大,术后随访3个月的Constant-Murley评分更高,而术后出现并发症更少,差异有统计学意义（P<0.05）。结论 与单纯钢板内固定相比,大结节锁定板联合高强线、肌腱韧带固定锚钉固定组具有更为满意的临床疗效,具有术后恢复快、对肩关节功能影响小、术后并发症少等优点。
