this deformity is often reffered to as thumbclutched hand, but a better term is the congenital clasped thumb. the congenital clasped thumb is associated with several well-de-fined syndromes, although it may also present as an isolated abnormality. weckesser, reac, and heiple called it a syndrome and divided the syndrome in to four groups. in group i, the thumb is deficient in extention only. in...

Polydactyly of the hand is a difficult problem and poses a unique challenge for the hand surgeon. The embryology of limb development is complex, leading to a host of different phenotypes of polydactyly. Polydactyly can occur in any digit and is described as preaxial, postaxial, and central, based on location. Classification systems exist for each of these locations, which guide treatment option...

In this study, removal of a transitional object (pillow) was applied as the sole intervention for one of two siblings who sucked their thumbs. The intervention was applied only to the older sibling, whereas data were collected on the thumb sucking of both participants. Results indicated that removal of the transitional object for the older sibling reduced thumb sucking in both siblings and incr...

From Biblical days, the occurrence of six toes instead of five, called polydactyly, has been known. Of late, there have been some individual case reports from USA and Italy. Moreover, a group formed from several countries has dealt competently with genetic studies of 19 preaxial polydactyly families. Therefore, we report a case from Nigeria.

BACKGROUND Polydactyly is the most common congenital hand deformity. There is currently no consensus among pediatricians or hand surgeons regarding optimal management of ulnar (post-axial) type B polydactyly leading to uncertainty in initial treatment decisions for infants with this type of deformity. METHODS Parents of newborns with type B ulnar polydactyly were enrolled in a prospective, no...

Two new pedigrees of polydactyly associated with brachymetapody are discribed. In one the two defects occur in different members of the family, while in the other both occur in the same individuals. Both anomalies appear to be inherited as dominants, the polydactyly showing incomplete manifestation.

Ellis-van Creveld syndrome (EVC) is a rare chondroectodermal dysplasia presenting several skeletal manifestations and congenital heart malformations. Polydactyly is the most frequent skeletal anomaly. The authors report two cases of EVC syndrome with different manifestations, which underwent surgical treatment for polydactyly.

Background We previously conducted a first-in-human clinical study of articular cartilage repair using autologous chondrocyte sheets and confirmed the regeneration of hyaline-like cartilage in all eight patients. However, regenerative medicine with autologous chondrocyte sheets requires the harvesting of tissue from healthy regions, and the quality of this tissue varies between individuals. To ...
