Movement of the distal carpal row during narrowing and widening of the carpal arch width.
Change in carpal arch width (CAW) is associated with wrist movement, carpal tunnel release, or therapeutic tunnel manipulation. This study investigated the angular rotations of the distal carpal joints as the CAW was adjusted. The CAW was narrowed and widened by 2 and 4 mm in seven cadaveric specimens while the bone positions were tracked by a marker-based motion capture system. The joints main...
متن کاملCarpal bone fractures.
Carpal bone fractures make up a significant proportion of injuries to the wrist. The complex bone shape and articulations make diagnosis more difficult and missed injuries more common. This article reviews carpal bone fractures excluding the scaphoid.
متن کاملCarpal Biomechanics: Application to Ligamentous Injuries
Since Destot in 1905, the study of intracarpal injuries has interested many authors who were faced with wrist traumatisms [ 1– 7 ] . Therefore, the analysis of the sole traumas is not enough to understand carpal biomechanics. Studies have thus been led in different directions to solve injuries’ mechanism. Imaging studies dealt with the radiography of healthy subjects [ 8– 17 ] , with the in vit...
متن کاملThe role of the transverse carpal ligament in carpal stability: an in vitro study.
A biomechanical in vitro study was performed on 16 fresh frozen cadaver forearms to investigate the role of the transverse carpal ligament (TCL) in carpal stability. The distance between the scaphoid and hamate was measured, as a reference for the length of the TCL. Distances were recorded in both loaded and unloaded conditions after gradual sectioning of the transverse carpal ligament, the pal...
متن کاملTensile properties of the transverse carpal ligament and carpal tunnel complex.
BACKGROUND A new sophisticated method that uses video analysis techniques together with a Maillon Rapide Delta to determine the tensile properties of the transverse carpal ligament-carpal tunnel complex has been developed. METHODS Six embalmed cadaveric specimens amputated at the mid-forearm and aged (mean (SD)): 82 (6.29) years were tested. The six hands were from three males (four hands) an...
