Objective To analyse the diagnosis and treatment methods for posterior dislocation of the shoulder joint combined with a reverse Hill-Sachs injury following an epileptic seizure.Methods A retrospective analysis of 8 cases of shoulder dislo-cation combined with reverse Hill-Sachs injury caused by epileptic seizures treated with surgery from January 2019 to April 2023 was conducted.The space between the pectoralis major and deltoid muscles was used as the surgical approach,and the fracture fragments were fixed cannulated screws after joint reduction.In some cases,subscapularis muscle transfer was per-formed.Postoperative outcomes were observed.The latest follow-up included clinical efficacy assessment based on patient satis-faction,pain VAS score,shoulder joint range of motion,and UCLA shoulder joint score.Results All patients were followed up for 4.9 to 7.5 months,with an average of 6.2 months.At the last follow-up,all patients'incisions healed well(grade A),frac-tures recovered well,and no adverse events such as recurrent dislocation or avascular necrosis of the humeral head were ob-served.At the last follow-up,the subjective satisfaction of the patients was as follows:2 cases were very satisfied,and 6 cases were satisfied;pain VAS scores were 0-2 points in 2 cases,3-4 points in 4 cases,and 5-6 points in 2 cases;active range of mo-tion of the shoulder joint:average of 133.6°(123.1 °-144.1 °)for forward flexion,average of 126.5°(114.8°-138.2°)for abduction,and average of 35.1°(20.8°-49.4°)for external rotation;UCLA shoulder joint scores averaged 29.3(26.5-32.1)points.Conclu-sion For posterior dislocation of the shoulder joint combined with a reverse Hill-Sachs injury caused by epileptic seizures,when the defect of the humeral head is less than 40％,surgical treatment through the deltoid-pectoralis major space approach can achieve good results and improve shoulder joint function.
