RESUMEN
PURPOSE: An endoscopic-assisted approach for Sprengel deformity has been previously reported. Our objective was to assess outcomes of the endoscopic Woodward procedure in a series of patients. METHODS: Retrospective analysis was performed of children with a Sprengel deformity treated between November 2014 and February 2018. Recorded data were demographic, pre- and postoperative active shoulder elevation and deformity severity according to Cavendish. RESULTS: A total of 12 children (four girls and eight boys, ten right-sided/two left-sided) with a mean age of nine years two months (3 years 5 months to 16 years 1 month) and mean follow-up 19.8 months (10 to 48) were assessed. Nine children were classified as Cavendish Grade III and three as grade IV, respectively. Mean preoperative active shoulder forward elevation was 100.8° (70° to 120°), while postoperatively it increased to 149.2° (100° to 170°). Mean preoperative scapular high difference was 4.5 cm (2.8 to 5.2), while postoperatively it was 1.33 cm (0 to 2.8). CONCLUSION: The endoscopic assisted Woodward procedure is an effective technique. Further comparative studies will ascertain advantages in functional and cosmetic results compared to the standard Woodward procedure. LEVEL OF EVIDENCE: Therapeutic study, Level IV.
