N.D. presented at 8 weeks of age because of concern over her small right thumb. She was unable to actively flex or oppose this thumb, and the first carpometacarpal joint was unstable. Radiographs showed a hypoplastic digit with undeveloped carpometacarpal joint (Fig. 1). The remainder of her examination showed normal findings.
