Carpal Angle Research Articles

The carpals in congenital malformation syndromes.

A variety of carpal anomalies may occur in the congenital malformation syndromes. These include the presence of extra carpals, abnormal carpals, and abnormalities of the carpal angle. Carpal fusion which affects carpals in different rows also has some significance, as do variations in maturational sequence. In some syndromes an increased incidence of anatomic variation may be found. The lack of good normal standards of carpal size and configuration and the lack of statistical data on the normal variability of these bones make evaluation subjective in most cases.Syndromes associated with carpal anomalies include arthrogryposis, diastrophic dwarfism, dyschondrosteosis, Ellis-Van Creveld syndrome, epiphyseal dysplasia, Fanconi’s anemia, Hand-Foot-Uterus syndrome, Holt-Oram syndrome, homocystinuria, OtoPalato-Digital syndrome, symphalangism, Trisomy 18, and Turner’s syndrome.

Radiologic Study of the Carpal Angle in Japanese

The carpal sign in gonadal dysgenesis.

ABSTRACT In 37 cases of gonadal dysgenesis (gonadal apasia) the dorsopalmar roentgenograms of the wrist and hand were taken in the neutral position, and abnormalities were found in the shape of the proximal carpal row. In order to obtain more precise data, 2 tangents were drawn, the first touching the proximal contour of navicular and lunate bones and the second touching the triquetral and lunate bones. The intersection of these tangents resulted in an angle called the carpal angle. From the measurements of this angle performed in 466 normal subjects, a mean value of 131.5° was obtained, while in all patients with gonadal dysgenesis the carpal angle was below the normal mean value. In addition, in half the patients with gonadal dysgenesis there was an abnormal angular shape of the proximal carpal row when the carpal angle was 117° or less; this was called the positive carpal sign. On roentgenograms of the wrist in control subjects the positive carpal sign was found in only 5.4%. Thus, the incidence of the...
