In humans, a single transverse palmar crease is a single crease that extends across the palm of the hand, formed by the fusion of the two palmar creases.Although it is found more frequently in persons with several abnormal medical conditions, it is not predictive of any of these conditions since it is also found in persons with no abnormal medical conditions.
A palmar crease is a type of crease on the palm. A single transverse palmar crease also called simian crease is sometimes associated with Down syndrome. [1] Other types of creases include the Sydney crease and the Suwon, or double transverse palmar crease. [2] Analysis of palmar creases is not very objective on the contrary to fingerprint ...
Minor physical anomalies (MPAs) are relatively minor (typically painless and, in themselves, harmless) congenital physical abnormalities consisting of features such as low-set ears, single transverse palmar crease, telecanthus, micrognathism, macrocephaly, hypotonia and furrowed tongue.
Cri du chat (5p-): abnormal dermatoglyphics, including single transverse palmar creases and triradii in the t' position on both hands, [4] are associated with 92% of patients, according to a critical review of multiple studies. [5] Congenital blindness: Initial data points to abnormal triradius. [6]
A wide variety of abnormalities of the hands and feet, including the nails and the creases of the hand, have been described and differentiated. [4] Many of these abnormalities do not have an impact on function but may be useful in diagnosing genetic syndromes; for example, the single transverse palmar crease is commonly associated with Down ...
The distal part of the palmar ligament, called the palmar plate, is 2 to 3 millimetres (0.079 to 0.118 in) thick and has a fibrocartilaginous structure. The presence of chondroitin and keratan sulfate in the dorsal and palmar plates is important in resisting compression forces against the condyles of the proximal phalanx. Together these ...
Odonto–tricho-ungual–digital–palmar syndrome is an autosomal dominant skin condition with salient clinical features of natal teeth, trichodystrophy, prominent interdigital folds, simian-like hands with transverse palmar creases, and ungual digital dystrophy.
With the incision of the transverse carpal ligament [18] [19] longitudinally, the median nerve is exposed. The release is extended to the superficial palmar arterial arch distally and for a limited distance proximally beneath the wrist flexion creases. [7]
