MATERIALS AND METHODS: Children with CRUS underwent corrective osteotomy based on radiographic planning; the extent of rotational correction and functional outcomes were assessed at a mean of 27 months after the operation.
RESULTS: Seven forearms in six children of an average of 6.25 years were assessed for correction and functional outcomes. The average pre-operative pronation deformity was 71.5°. The average correction achieved was 64°. At follow-up, there were five excellent and two good functional outcomes. All children could perform daily tasks besides eating with hand and personal hygiene.
CONCLUSION: Radiographic determination of the osteotomy sites by the method described is effective, consistent, and reproducible in achieving optimal functional outcomes in congenital radioulnar synostosis.
