Previous reports indicated malrotation of the scapula toward inferior would be associated with Sprengel's deformity. We have reported short term results of a novel method, a partial scapular resection, a removal of the omovertebral bone and a partial trapezius muscle transfer for improvement of scapula abduction. The purpose was to evaluate the mid-long term clinical results of the new surgical procedure for Sprengel's deformity.
The novel surgical procedure had been performed for three Sprengel's deformities, 1 male and 2 female patients (age range. 3 to 4 years old). The mean follow-up period was 83 months. They were evaluated by range of motion, Cavendish classification, x-ray, and CT scan.
The range of flexion/abduction improved postoperatively from 97/103 to 167/170. The cosmetic appearance improved by a mean of 2 levels on the Cavendish scale. The final average scapular lowering was 1 vertebral height compared with the initial radiographic examination. The angles of the glenoid toward spinal line improved from 72.5 to 49.5 degrees.
The range of motion, the cosmetics of the shoulder and the original malrotation of the scapula was improved and maintained by this surgical procedure in the mid-long term.
