ABSTRACT
PURPOSE:
To study the long-term results of radial club hand, regarding ulna growth, radial angulation, and volar subluxation using a 2-stage treatment protocol.METHODS:
From 1998 to 2009, 39 radial club hands (32 patients) were treated with distraction, radialization, and a bilobed flap. Long-term follow-up was available in 13 patients (17 hands; average 12.6 years, range 9-16 years). All 17 hands were classified as Bayne and Klug grade 3 or 4.RESULTS:
The average age at distraction was 12 months (SD 5.3). The average age at radialization was 14 months (SD 5.8). At final follow-up, the average ulna length on the involved side was 69.3% of the uninvolved contralateral side in the unilateral cases. In the 4 bilateral cases, the average ulna length was 62% of the ulna length of a cohort of normal children. The transverse diameter of the ulna in the posteroanterior view was 79%, and in the lateral view 99%, of the radius on the contralateral side in the unilateral cases. The average radial deviation improved from 82° to 8° and the average volar subluxation improved from 20° to 12°. However, in 4 hands recurrent volar subluxation and required revision surgery.CONCLUSIONS:
This approach to treatment was associated with consistent results in the correction of the radial angulation, volar subluxation, and ulna growth in long-term follow-up. Volar subluxation may result in a requirement for revision. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.Palabras clave
