[Median clefts of the hand. Classification and therapeutic indications apropos of 29 cases].
Based on a series of 29 patients with median clefts of the hand (29 hands), the authors define the place of this malformation, its various clinical features and the therapeutic indications. The series consists of 13 boys and 7 girls, 9 bilateral cases and 11 unilateral cases. Involvement of the feet was observed in 9 cases. Several children also presented other malformations. 16 children were operated (22 hands). Two types of technique were used: simple closure of the cleft (Barsky's operation) and transposition of the index finger according to the Snow-Littler or Miura-Komada techniques. All operated patients were reviewed with a follow-up of more than one year and the results were assessed in terms of three criteria: overall use of the hand, thumb-index finger pinch grip, aesthetic appearance. The authors propose a new classification of median clefts of the hand based on examination of this series of 20 children: simple clefts with more or less complete absence of the middle finger, complex clefts with syndactyly (especially I and II), transverse bone polydactyly, extensive clefts with severe aplasia of the radial segment of the hand. Clinical and radiological examination confirm the experimental studies by Ogino. Barsky's operation gives satisfactory results in simple forms with parallel fingers. Translocation of the index finger to the base of the 3rd metacarpal is necessary in the presence of divergent fingers and syndactyly. Median clefts of the hand are very distinct from median aplasia, which is always unilateral, with no familial nature and no involvement of the feet and which can be classified together with brachysyndactyly. Each case must be studied before deciding treatment, as functional adaptation is always remarkable. The least favourable surgical results are observed in forms with abnormal position of the index finger (malrotation syndactyly). Lastly, the Snow-Littler operation is not devoid of complications.
