ABSTRACT
PURPOSE: The authors applied modified Bilhaut-Cloquet procedure to convergent type of Wassel type IV duplicated thumb. In order to avoid secondary Z-deformity and dysfunction of the reconstructed thumb, the authors modified operative techniques of Bilhaut-Clopuet procedure. METHODS: Fourteen patients received Bilhaut-Cloquet procedures to correct duplicated thumbs from October 2008 to May 2013. Five patients were balanced type and nine patients were unbalanced type. Mean age at the operation was 20.1 month-old (range, 12-52 month-old). Angular deformity, joint stability, range of joint motion and cosmetic outcome were estimated based on Tada score. Postoperative subjective satisfaction score of the parents was evaluated using a 100-points scale. RESULTS: Mean subjective satisfaction score was 75 points at 28 months after the operation. Radiologic study showed bony union of proximal phalangeal bone and stable joint in all patients. Mean range of motion was 20 degrees in interphalangeal joint and 73 degrees in metacarpophalangeal joint. Based on Tada score, the results were good in ten patients (72%), fair in two (14%) and poor in two (14%). Seven patients who were able to follow up for a long term showed no significant difference in length of proximal and distal phalangeal bones compared to the opposite thumb. CONCLUSION: Modified Bilhaut-Cloquet procedure can be applied not only to balanced type of convergent Wassel type IV duplicated thumb, but also to unbalanced type, that focused on functional reconstruction and cosmetic improvement.

PURPOSE: The authors applied Bilhaut-Cloquet procedure to Wassel type III and IV duplicated thumb, which was limited to patients with Wassel type I, II. This procedure was applied in order to improve the growth potential, range of joint motion, joint stability and cosmetic outcome. METHODS: Sixteen patients received Bilhaut-Cloquet procedures to correct duplicated thumbs from May, 2005 to December, 2010. Seven patients were Wassel type III, nine patients were type IV. This procedure was applied not only to balanced type, but also unbalanced type or convergent type. Five patients were balanced type and eleven patients were unbalanced type. Convergent type of Wassel type IV was three. Sex ratio was the same, mean age at the operation was 20.1 months old(8~52 months old). Angular deformity, joint stability and range of joint motion and cosmetic outcome were considered together and estimated in Tada score. Also, postoperative subjective satisfaction score of the parents was evaluated by a 100-points scale. RESULTS: Mean subjective satisfaction scored 75 points at 28 months after the operation. Radiologic study showed bony union of proximal phalangeal bone and stable joint in all patients. Range of motion was mean 20 degrees in interphalangeal joint and mean 73 degrees in metacarpophalangeal joint. Tada score showed 'good' in eleven patients(68.8%), 'fair' in three patients(18.7%) and 'poor' in two patients(12.5%). In seven patients those who were able to follow up for a long term showed no significant difference in length of proximal and distal phalangeal bones compared to the opposite thumb. CONCLUSION: Bilhaut-Cloquet procedure can be applied not only to balanced type of Wassel type III, IV duplicated thumb, but also to unbalanced type or convergent type that focused on functional reconstruction and cosmetic improvement.

Introducción. La polidactilia se define como un exceso de dígitos o partes en manos o pies. La polidactilia del pulgar (preaxial) es la más común en la población blanca y asiática. Es importante el manejo quirúrgico temprano para evitar deformaciones en el dígito afectado. Métodos. Estudio retrospectivo de los pacientes que ingresaron al Instituto Nacional de Pediatría con diagnóstico de polidactilia preaxial en el período de marzo de 2001 a febrero de 2003. Resultados. Se diagnosticaron 57 pacientes, con edad promedio de 19 meses. Predominaron pacientes del sexo masculino (n =41) sobre los del femenino (n =16). Se encontraron 2 pacientes con pulgar duplicado en ambas manos, 39 pacientes en mano derecha y 16 en mano izquierda (total =59). El tipo IV de Wassel fue el más frecuentemente encontrado. A todos los pacientes se les realizó manejo quirúrgico. Se presentaron 10 pacientes (16.94%) con secuelas menores postoperatorias. Conclusiones. La casuística reportada en este trabajo es significativa. La correcta clasificación de esta malformación es importante para realizar una cirugía adecuada que tenga como objetivo la restauración funcional y estética de la mano.
Introduction. Polydactyly is defined as an excess of digits or parts in the hand or foot. Thumb (preaxial) polydactyly is commonly found in white and Asian populations. Early surgical management is important to avoid deformations in the affected digit. Methods. Patients were seen at the Instituto Nacional de Pediatria with a diagnosis of preaxial polydactyly during the period from March 2001 to February 2003. Results. Fifty seven patients with an average age of 19 months were observed. We found a prevalence of the masculine (n= 41) in comparison with the feminine gender (n= 16). Two patients had a duplicated thumb on both hands: 39 patients on the right and 16 on the left hand (total= 59 duplicated thumbs). Wassel type IV was the most frequently found polydactyly. All patients had surgical management; 10 patients had minor postsurgical residual deformities. Conclusions. The casuistic reported in this work is significant. Proper classification of this abnormality is important to offer the patient the proper surgery for restoring the hand’s function and aesthetics.
ABSTRACT
Since 1985, 7 symmetrical thumb polydactylies were treated with Bilhaut-Cloquet operation (V-shaped wedge out). As for Wassel's classification, two cases were type I (duplicated distal phalanx but not epiphysis) and two type IV (duplicated proximal and distal phalanx), and three type II (duplicated distal phalanx and epiphysis). Preoperatively, thumb polydactylies must be symetric and cut articular surfaces be accurately approximated. As for Wassel's type IV polydactyly, preoperative angiogram was done for detection of any vascular anomalies and tried not to damage the anomalous digital arteries of thumb. There was no postoperative complications. All patients and their parents were much satisfied with the postoperative results, but somewhat limited thumb motions were remained. In type I (2 cases) the average IP joint range of motion was 39°, in type II (3 cases) the average IP joint range of motion was 22°, and in type IV (2 cases) the average range of motion of IP joint was 21° and MP joint was 26°.
