Sprengels deformity is not just the malposition of the scapula, but it is also often associated with dysplasia of muscles around the scapula. We studied the influence of this dysplasia on the treatment of modified Woodwards method. We observed twelve patients ( 3 males, 9 females) of whom we could evaluate the muscles around the scapula by 3DCT and MRI before surgery. The operation method was modified Woodwards method in which we lowered the scapula after osteotomy of the clavicula. In the case with dysplasia of muscles, the scapula moved to a higher position at the final observation compared to the position soon after the surgery. The abduction improved from 96 degrees(on average)before the surgery to 146 degrees. As for complications, two keloid scars and one temporary cranial nerve palsy were found. Woodwards method observed improvement of functions and less complications. However, in the case with dysplasia, as there was limited improvement aesthetically and there were also some relapses, long-term follow-ups are necessary.
