Outcome of mears procedure for Sprengel′s deformity

Background: Sprengel′s shoulder is characterized by scapular maldescent and malposition, causing restriction of shoulder and cervical spine movements. It is associated with a variety of other congenital anomalies. Various surgical procedures have been described to treat this anomaly with no consensus as to the surgical procedure of choice. We report the results of the Mears procedure in the treatment of Sprengel′s shoulder. Materials and Methods: Seven children between the age group of two and six years were treated for Sprengel′s deformity, with omovertebral bar, and other congenital anomalies. The Cavendish score and Rigault radiological score were used to assess the severity of the deformity, and the position of the scapula relative to the cervical spine, respectively. The Mears procedure involved scapular osteotomy, par tial scapular excision, and release of a long head of triceps. Clavicular osteotomy was done only in two cases to decrease the risk of traction injury to the brachial plexus. Postoperatively, the patients were immobilized in a shoulder sling and range of motion exercises were started as early as possible. The patients were followed regularly at six weeks, three months and regularly at six-months interval. Results: The mean improvement in flexion and abduction was 45 ° (40 - 70 ° ) and 50 ° (40 - 70 ° ), respectively, which was the combined glenohumeral and thoracoscapular movement. The cosmetic and functional improvement by this procedure was acceptable to the patients. Minor scar hypertrophy was seen in two cases. Conclusion: The Mears procedure gives excellent cosmetic and functional results. This procedure addresses the functional aspect of the deformity and is much more acceptable to the patient and parents.
