Abstract

A 3-year-old girl presented with absent active interphalangeal thumb flexion due to isolated congenital absence of the flexor pollicis longus. Imaging confirmed the diagnosis. A 2-stage reconstruction was performed with silicone rod placement, pulley reconstruction, and subsequent flexor digitorum superficialis tendon transfer with restoration of useful thumb flexion and improvement in hand function. Postoperatively, the patient achieved functional thumb flexion, and no recurrence was found at the end of 2 years of follow-up.
Early recognition of isolated flexor pollicis longus agenesis allows appropriate surgical planning. A 2-staged tendon reconstruction can restore functional thumb flexion and improve fine motor skills in pediatric patients.
