Central polydactyly is the rarest form of digital duplication, representing only 5-15% of all cases23-06-2026 15:35:00. We report the case of a 13-year-old girl presenting with symptomatic central polydactyly (Wall type 1 A) with late-onset pain and functional limitation. Radiographic evaluation demonstrated a bifid third metacarpal consistent with Tada type II classification. Surgical management involved resection of the supernumerary digit combined with a subtraction osteotomy of the third metacarpal and intertendinous suturing to restore axial alignment and centralize the extensor mechanism. At 3-year follow-up, the patient demonstrated excellent functional and aesthetic outcomes. This case highlights the importance of addressing both skeletal deformity and tendon imbalance in delayed presentations of central polydactyly.
