short second metacarpals. She was the product of an uncomplicated pregnancy and delivery. Psychomotor development had been entirely normal. Her only physical abnormalities were marked shortening of both second fingers. There were no abnormal dermatoglyphic patterns, except for a transverse palmar crease which was most prominent over the midportion of the second metacarpal. X-rays showed a lack of ossification of the midportion of this metacarpal, shortening of the over-all length, and a normal proximal epiphysis (Fig. 1). There were no deformities of the toes or metatarsals. At the age of three years she underwent surgery on the left hand. The index metacarpal was found to be somewhat dumbbell shaped with a narrow cartilaginous bridge between two ossified ends. The distal end was sufficiently large to split transversely, separate for a distance of 1.2 cm., and insert an appropriately shaped iliac bone graft which was secured with a single Kirsctiner wire. A concomitant soft tissue and intrinsic release was done. Postoperatively the finger has assumed a more Woportionate length. Future plans include a similar procedure on the right index metacarpal and possibly a repeat bone grafting in later years depending o n the growth characteristics of the metacarpals. The mother of this child had a similar shortening of the right second finger. Like her daughter, she had a transverse palmar crease and deep groove in the skin overlying the midportlon of the shortened metacarpal. X-rays showed that she had no ossification of the midportion of the second metacarpal in the right hand (Fig. 2). In view of the operative findings in her daughter we assumed a cartilaginous bridge was present between the ossified areas. She had no other

Neither the proposlta's younger sister nor either of the mother's sibs ~or parents has a similar deformity. DISCUSSION

We have not found any reports of a similar hereditary deformity of the second meta-

carpal. Barsky s has commented that absence of the metacarpals occurs either as an isolated abnormality or in conjunction with missing digits. H e noted that the "absent" metacarpal of an infant is palpable and subsequently becomes ossified. Shortening of the fourth metacarpal, apparently nonhereditary, has been reported by Bogin. 4 Shortening of the fourth metacarpal in a mother and her

son was reported by Newcombe and Keats. 5 The deformity was unilateral in the mother (Case 6) and bilateral in her son (Case 8). Shortening of several metacarpals is a feature of patients with brachydactyly, type E, but they also have shortening of the metatarsals, phalanges, and long bones?, 5 Furthermore, in individuals with brachydactyly, type E, the shortening of the digits is not evident at birth and there is no midshaft ossification defect, as in our proposita and her mother (Figs. 1 and 2). Surgical correction of this anomaly has not been reported and none of the reported individuals 3-5 with short metacarpals was treated. The mother of our proposita stated that her own unilateral deformity had been a significant handicap; for this reason she requested treatment for her daughter's hand deformity. Surgery was performed on this young girl because of the beneficial effects of restoring or maintaining normal tendon balance in de-

veloping fingers. We believe that surgical correction should be carried out as soon as there is a large enough bony segment to receive a graft without interfering with the presumed growth centers in the cartilaginous segment.
