Systematic review of winged scapula

Objective To study the morbidity, pathogenesis, diagnosis and treatment of scapula. Methods The key words about winged have been used to search articles which include scapula patients in English and Chinese literature databases from 1958 to 2017. The articles have been filtrated by title, abstract and full text. There are 36 articles used for this study. All the patients are objects of this study, but the same patients' data in different articles have not been used repeatedly. The patients' data have been collected as much as possible, including age, sex, causes, treatment, follow-up and so on. All the patients' data have been used for systematic analysis. Results All of 356 patients with scapula were selected from 36 literatures for systematic analysis. There were 213 cases of anterior saw muscle paralysis, among which 16 cases were physical exercise, 11 cases were excellent and 5 cases were poor, with an excellent rate of 68.8%. There were 70 cases of neurolysis and transplantation, 50 cases were excellent and 20 cases were poor, with an excellent rate of 71.4%. There were 3 cases of scapulectomy, 1 case excellent and 2 cases poor. There were 124 cases of pectoralis major tendon metastasis, 88 cases were excellent, 36 cases were poor, and the excellent rate was 71%. There were 46 cases of trapezius paralysis, among which 14 cases were physical exercise, 12 cases were excellent, 2 cases were poor, and the excellent rate was 86%. 1 case of scapulopexy and 1 case of superior, with an excellent rate of 100%; There were 31 cases of Eden-Lange 31 cases, 27 cases of excellent and 4 cases of poor. One case of rhomboid myoplegia was treated, including 1 case of rehabilitation training (ultrasound guidance), 1 case of excellent, with an excellent rate of 100%. There were 96 cases of muscular dystrophy, including 96 cases of scapulectomy, 76 cases of excellent and 20 cases of poor, with an excellent rate of 79.1%. Conclusion Winged scapula is rare and its incidence is unknown, different causes determine different treatments: Anterior saw muscle palsy is more suitable for thoracolumbar tendon transfer, and modified Eden-Lange is more suitable for trapezius palsy.
