356 the opponens roll maneuver and “highamplitude springing” of the carpal bones. It is essential to apply vigorous manipulative release of the TCL at the distal carpal bone level (trapezium-hamate), and the results can be documented by palpatory assessment after treatment, as noted by my 1994 study4 when using a Likert-type rating scale of 0 to 5 (0=no restriction, 5=extremely marked restricti...

Abstract
 Background: In this study, we examined whether carpal bones (lunate, hamate, capitate) morphologies and fourth metecarp-capitate articulation have an effect on the distal radius fracture pattern.
 
 Methods: 206 patients who applied to emergency department with between 2016-2020 were included in study. Preoperative pre-reduction x-ray films of examined. Lunate, capitate...

INTRODUCTION: Clinical studies of carpal tunnel syndrome (CTS), a pressure-induced neuropathy of the median nerve, are limited by the difficulty of evaluating the early stages of pathology. Thus, a validated animal model of CTS is an important need. A proper animal model would have comparable anatomy to the human carpal tunnel. In addition, because carpal tunnel syndrome is characterized by inc...

Using gene targeting in mice, we have undertaken a systematic mutational analysis of the homeobox-containing 5' HoxD genes. In particular, we have characterized the limb defects observed in mice with independent targeted disruptions of hoxd-12 and hoxd-13. Animals defective for hoxd-12 are viable, fertile, and appear outwardly normal yet have minor autopodal defects in the forelimb which includ...

Functional limitations and pain are end results of scaphoid nonunion with progressive carpal collapse and radiocarpal arthritis. The aim of this study was to assess the functional outcome of four-corner arthrodesis with scaphoidectomy for the treatment of grade IV scaphoid nonunion with Scaphoid Nonunion Advanced Collapse (SNAC) stages II and III. Ten patients with symptomatic grade IV non unio...

From early dinosaurs with as many as nine wrist bones, modern birds evolved to develop only four ossifications. Their identity is uncertain, with different labels used in palaeontology and developmental biology. We examined embryos of several species and studied chicken embryos in detail through a new technique allowing whole-mount immunofluorescence of the embryonic cartilaginous skeleton. Bey...

BACKGROUND The radioulnar carpal joint is critical for hand and wrist function. Radioulnar deviation indicates distal radioulnar joint flexibility and reflects the structure and function of the carpal bones, ulna, radius and ligaments. The present study examined whether radioulnar deviation is affected by gender, manual labor, playing a musical instrument, playing sport, handedness, previous fr...

ABSTRACT Ritscher-Schinzel Syndrome (RSS) is a clinically variable, autosomal recessive disorder, involving cardiac, cerebellar and craniofacial abnormalities. Numerous reports describe hand changes in RSS patients; however, a detailed characterization of the hands has not previously been performed. OBJECTIVE The purpose of this study was to identify whether specific radiographic hand changes...
