Scapular hypoplasia, elevation and rotation deformity are accompanied by progressive dislocation of the humeral head. Between February and August 2005, 44 children underwent a new surgical procedure called the \u2018triangle tilt\u2019 operation to correct this bony shoulder deformity. Surgical levelling of the distal acromioclavicular triangle combined with tightening of the posterior glenohumeral capsule (capsulorrhaphy) improved shoulder function and corrected the glenohumeral axis in these patients. The posture of the arm at rest was improved and active external rotation increased by a mean of 53\u00b0 (0\u00b0 to 115\u00b0) in the 40 children who were followed up for more than one year. <\/jats:p><jats:p> There was a mean improvement of 4.9 points (1.7 to 8.3) of the Mallet shoulder function score after surgical correction of the bony deformity. <\/jats:p>","DOI":"10.1302\/0301-620x.89b12.18757","type":"journal-article","created":{"date-parts":[[2007,12,5]],"date-time":"2007-12-05T22:53:07Z","timestamp":1196895187000},"page":"1638-1644","source":"Crossref","is-referenced-by-count":32,"title":["Surgical correction of the medial rotation contracture in obstetric brachial plexus palsy"],"prefix":"10.1302","volume":"89-B","author":[{"given":"R.
