Congenital bilateral hypoplasia of the radius and ulna associated with Camptodactyly: A Case Report

Introduction: Congenital hypoplasia of the forearm bones is a rare longitudinal anomaly that can affect the radius, ulna, or both bones simultaneously. Combined bilateral involvement is exceptional and may be associated with digital malformations.

Case presentation: We report the case of a 6-year-old boy with bilateral hypoplasia of the radius and ulna associated with bilateral camptodactyly of the 4th and 5th fingers. Clinical examination revealed limited extension of the affected wrists and proximal interphalangeal joints, with preserved muscle strength and grip. Standard radiographs confirmed bilateral hypoplasia of both forearm bones without major carpal instability.

Discussion: Longitudinal malformations of the forearm are classified according to international classifications and their anatomical and radiological characteristics. Management depends on the functional impact and is initially based on conservative treatment, with surgery reserved for progressive or functionally disabling forms.

Conclusion: Rigorous clinical and radiological evaluation, combined with international classifications, allows the therapeutic strategy to be adapted and the functional prognosis to be optimized.
