Simultaneous three-dimensional correction of percutaneous radial osteotomy with circular external fixator in Madelung's deformity.

Partial deficiency of distal radial and volar cartilage plate growth is the main pathology in Madelung's deformity. Surgical treatment can use a Taylor Spatial Frame (TSF) external fixator, which provides simultaneous multiplanar correction and lengthening after radial osteotomy, sparing Vickers' ligament and the ulna. We sought to evaluate the radiological and functional results of Madelung's deformity correction by TSF, by retrospectively analyzing eight Madelung's deformities in seven patients between August 2011 and May 2015. Mean age was 14.8 years (range, 11-26), and mean follow-up 35.1 months (24-78). We evaluated demographic data and pre- and post-operative radiological and functional results. Mean preoperative visual analog pain scale score improved from 7.7 to 1.6. Mean preoperative DASH score improved from 19.1 (9.5-46.6) to 3.7 (2.3-6.8). Mean preoperative radial length improved from 184 mm (138-209) to 196 mm (142-213). We think that software-based correction using a TSF is a safe solution in Madelung's deformity, with minimal margin of error and risk of postoperative stiffness and infection. LEVEL OF EVIDENCE: IV.
