Polydactyly being most common congenital digital anomaly of the hand and needs special consideration. Surgical treatment is warranted in most of the cases because of cosmetic and functional reasons. In this article, we describe a 5-year-old female child who was having bilateral thumb duplication. The diagnosis was clinical, and it does not fit into any mentioned classification systems in litera...

BACKGROUND The purpose of this study was to present a novel surgical technique using an on-top osteotomy and to assess the clinical and radiographic outcomes for the triphalangeal Wassel type VI thumb duplication patients. METHODS The surgical technique involves ablation of the radial thumb at distal one-third of the metacarpal, corresponding metacarpal osteotomy of the ulnar thumb, with amal...

Wassel VI radial polydactyly is associated with metacarpal adduction and deviation of the metacarpophalangeal joint ulnar duplicate. The soft tissue abnormalities responsible for these deformities were characterized using preoperative multi-planar three-dimensional ultrasound intraoperative observation in four patients. In all patients, abductor pollicis brevis superficial head flexor inserted ...

F syndrome (acropectorovertebral syndrome) is a dominantly inherited skeletal dysplasia affecting the hands, feet, sternum, and lumbosacral spine, which has previously been described in only two families. Here we report a six generation Turkish family with a related but distinct dominantly inherited acropectoral syndrome. All 22 affected subjects have soft tissue syndactyly of all fingers and a...

The operation method for thumb polydactyly has developed from simple removal, and it has become the standard procedure at present to collect parts to be used from each of the components and reconstruct one thumb. Traditionally this has been accomplished by the bisecting and joining procedure, known as Bilhaut-Cloquet's method, for the distal phalangeal type, and by the extended bisecting and jo...

Werner mesomelia is characterized by a sequence variation in the specific region (position 404) of the enhancer ZRS of SHH. The phenotype comprises variable mesomelia, abnormalities of the thumb and great toe and supernumerary digits. We describe extensive variation in limb phenotype in a large family and report on a novel sequence variation NG_009240.1: g.106737G>T (traditional nomenclature: Z...

INTRODUCTION "On-top" and "side-to-side" plasties are techniques used for treating thumb duplications in which one thumb is adequate proximally and the other thumb contains a better pulp and nail distally. The detailed functional results of these techniques have not been reported in the literature. We report on two cases. PRESENTATION OF CASES The first case had Wassel type VI duplication. Th...

Congenital hypoplasia of thumb is rare malformation which is less likely to appear as an isolated entity. Four independent subjects exhibiting various grades of underdeveloped first digital ray were recruited. The affected autopods had narrow palms, medial or valgus inclinations of index fingers and thenar weakness, while the postaxial digits were least affected. According to the classification...
