Subperiosteal resection of mid-clavicle in Sprengel's deformity correction.

We report the results of fifteen cases of Sprengel's deformity treated surgically by initial subperiosteal resection of the middle third of the clavicle in conjunction with surgical release of all attachments of the scapula to the spine, excision of any omovertebral bone and resection of prominent supraspinous process of scapula. The patients included ten female and three male patients (age range at the time of operation, 3.3-10 years; mean: 6.11 years). The deformity involved the left shoulder in eight patients, the right shoulder in three and two were bilateral. All patients were followed for an average of 5.9 years (range 4-11 years). Preoperatively, the arc of total abduction (glenohumeral and scapulothoracic) ranged from 80 to 140°, and the average was 110°. The shoulders were level, and the range of motion was dramatically improved with an average range of abduction of 166.5° (range 140-180°). The age of the patients and the presence of an omovertebral bone did not influence the results. All patients and their parents expressed satisfaction with the operative results. We feel that our procedure is a simple one, which helps to improve the degree of correction, avoid neurovascular complications and has the advantage of complete regeneration of the clavicle. The technique provides an easy, safe method of repositioning the scapula at its normal level.
