From a mechanical point of view, the wrist represents the most complex joint in the body, providing a large range of motion in the flexion-extension (FE) and radial-ulnar-deviation (RUD) planes. Anatomically, the wrist could be divided into two carpal rows. Deeper insight into wrist biomechanics is highly desirable, because the complex wrist structure causes a variety of possible injuries and t...

Carpal tunnel syndrome is prevalent in patients who have a repetitive motion, vibration, or pressure exerted on the wrist joint for an extended period of time. The prevalence of this condition in the general population is approximately 5%. Motorcyclists subject themselves to high levels of vibration from the road and use their wrists to control the motorcycle's brakes, gas intake, and gears via...

In the past ten to fifteen years, investigators have demonstrated conclusively that some injuries about the wrist have profound long-term consequences relative to function of the wrist. Problem fractures and non-unions of the scaphoid have been associated, in particular~ with major alterations in the kinematics of the wrist8’64. Considering its vulnerable blood supply~-4, irregular shape, pecul...

The wrist represents a complex anatomic region in the human extremity and a highly functional and intricate structural joint. Most perilunate injuries result from a staged disruption of the ligamentous structures. Forces may be directed through the carpal bones themselves resulting in a fracture. Early anatomic reduction of any carpal malalignment is of the utmost importance. Unfortunately, eve...

The volar divergent dislocation of the second to fifth carpometacarpal joints and involving fracture carpal is an extremely rare injury. We reported a case 55-year-old man, victim motorbike, who was struck by car, admitted at emergency department unable move his left hand with severe swelling. X-rays CT scan showed carpal. Patient underwent closed reduction plaster fixation right way, after one...

Abstract The “carpal boss” is a variant present in 19% of the population according to cadaveric studies but becomes symptomatic only 1% cases. With rising popularity “yoga,” which includes prolonged hyperextension at wrist joint with weight bearing, an increasing number individuals silent carpal boss dorsal pain due impingement over soft tissues by this innocuous bony protuberance. This warrant...

5 Treatment of Dyslipidemia in Patients With Chronic Kidney Diseases A In 1972, the Mayo Clinic Department of Orthopedic Surgery opened a new frontier of diagnosis and treatment of wrist injury with the publication of a classic paper by Ronald L. Linscheid, MD, and James H. Dobyns, MD. In it, the investigators set forth a framework for understanding carpal instability that influenced many subse...

Synostosis of carpal bones originates from lack of cavitation at the site of the future joint space with subsequent chondrification and ossification during the 4 to 8 weeks of intrauterine life. It is mostly seen as a chance finding discovered on radiographs. These coalitions are often asymptomatic, but can give complaints after trauma. We report six patients with different congenital carpal co...

Osteoarthrosis (OA) of the antebrachiocarpal joint from 7 riding horses is described. The horses were old mares and developed severe OA, with ankylosis in some of the joints. The lesions were bilateral, and the owners noticed the lameness in a late event. The cause of severe OA in these mares is not clear. The fact that OA was bilateral indicates that a single traumatic injury is unlikely as an...

Understanding the kinematics of the carpus is essential to the understanding and treatment of wrist pathologies. However, accurate measurement of the kinematics of the carpal bones is difficult because they are small bones undergoing complex movements of small amplitudes. As a result, to date, there is no clear consensus on carpal kinematics. Moreover, most studies only investigate single rotat...
