The purpose of this study was the evaluation of surgical outcomes in a series of wrists with Madelung's deformity treated with radial corrective osteotomy. We hypothesize that this surgical technique is a suitable and safe way of treatment. A retrospective review of patients with Madelung's deformity treated with radial corrective osteotomy between January 2001 and June 2017 at a single large department of hand surgery in Germany was performed. Patients who met the inclusion criteria were invited for follow-up and outcome variables including pain, range of motion, patient-rated outcome measures, and radiographic measurements were obtained for comparison with preoperative data collected from the patients' medical records. 14 wrists were included. The average age at the time of surgery was 21.9years, and the average follow-up was 7.2years. The average visual analog pain scale at rest decreased from preoperative 2.6 points to postoperative 0.7 points. Under strain, the average VAS declined from 7.4 to 4.9 points. The mean DASH Score decreased from 42.9 before surgery to 22.0 points after surgery. Range of motion improved slightly in five out of six directions of motion, with the greatest increase seen in average supination from preoperative 68.5° to postoperative 82.0°. Averages of all five measured McCarroll's parameters and ulnar variance decreased, as expected from corrective surgery. Four wrists (26.8%) needed subsequent procedures. Radial corrective osteotomy was a suitable treatment of Madelung's deformity in our collective, although surgical outcomes are not yet fully satisfying.
