Patient-Reported Outcomes in Children Undergoing the Modified Green Procedure for Treating Sprengel's Deformity: Results from a Multicentric Study.

backgroundSprengel's Deformity (SD) is a rare condition of the shoulder girdle, appearing as the principal congenital anomaly of the shoulder in paediatric patients. The aim of this study is to document the combined experience of two paediatric orthopaedic departments in managing SD using the modified Green Procedure, with a specific emphasis on the clinical and functional outcomes reported by patients; Methods: from June 2010 to February 2023, 42 shoulders in 40 paediatric patients were surgically treated for SD at two paediatric orthopaedic departments. All patients were treated using the modified Green Procedure with or without clavicle osteotomy. To better evaluate the deformity, the Cavendish's classification for aesthetic appearance and the Rigault's classification for radiological aspect were used, while movements of abduction and flexion were quantified to assess shoulder mobility. Several dedicated questionnaires such as QuickDASH, the Shoulder Pain Index and the Shoulder Disability Index (SPADI) and finally the UCLA Shoulder Scale were submitted to assess the quality of life of the subjects and the ability to practice certain activities, including work and sports. Complications were evaluated according to the modified Clavien-Dindo-Sink classification; Results: The mean follow-up was 5 years (range, 1.0-13.6). Clavicular osteotomy, performed in 15 patients, improved post-operative abduction by a mean of 25° (95% CI: 11-39°;
