Bones of Wrist Joint. The wrist joint (also known as the radiocarpal joint) is a synovial joint in the upper limb, marking the area of transition between the forearm and the hand.In this article, we shall look at the structures of the wrist joint, the movements of the joint, and the relevant clinical syndromes.Like any synovial joint, the capsule is dual layered. These techniques are used to increase generalized wrist mobility and open the joint spaces, allowing for greater movement into wrist extension since it is the closed-packed position of the wrist.

The internal layer is comprised of a synovial membrane, secreting synovial fluid which lubricates the joint.There are four ligaments of note in the wrist joint, one for each side of the joint Fig 2 – Palmar view of the ligaments of the wrist joint.The wrist joint receives blood from branches of the dorsal and palmar carpal arches, which are derived from the Innervation to the wrist is delivered by branches of three nerves:All the movements of the wrist are performed by the muscles of the forearm.The scaphoid bone of the hand is the most commonly fractured In a fracture of the scaphoid, the characteristic clinical feature is pain and tenderness in the Patients with a missed scaphoid fracture are likely to develop Fig 4 – The blood supply to the scaphoid bone runs from distal to proximal.This manifests clinically as paraesthesia in the sensory distribution of the median nerve and weakness of thenar muscles. The fibrous outer layer attaches to the radius, ulna and the proximal row of the carpal bones. Wrist joint supports movement of hand and forearm. Ulnar bone is not in contact with carpal bone at rest, but during supination and pronation, the carpal bone gets linked to ulna to optimize the rotation.Wrist joint is a flexible joint and involves 15 bones in forming three sections of wrist Joint.There are several ligaments between Radius, Ulna, Carpal Bones and Metacarpals.Tendons are tough bundle of fibrous tissue that anchors muscles to joint and bones. Joint movements observed at wrist joint are flexion, extension, abduction and adduction.Tendons and muscles supporting wrist joint movements are as follows-Pronation and Supination is rotation of forearm that involves minor rotation of radius over ulna.This article on Epainassist.com has been reviewed by a medical professional, as well as checked for facts, to assure the readers the best possible accuracy.We follow a strict editorial policy and we have a zero-tolerance policy regarding any level of plagiarism. The distal radioulnar joint allows you to flip-flop each hand at the wrist. The wrist is a complex joint that marks the transition between the forearm and hand. Anterior and posterior ligaments support the joint (in other words, these ligaments are close to the front and to the back of the wrist, respectively). Its a synovial joint that allows for a lot of movement; its formed where the head of the ulna articulates with the ulnar notch of the radius.

Palmar radiocarpal – It is found on the palmar (anterior) side of the hand. Muscle contraction pulls tendon toward the contracting muscles. Ulnar deviation, otherwise known as ulnar flexion, is the movement of bending the wrist to the little finger, or ulnar bone, side. The numbers in the parentheses (1, 2, 3) are clickable links to peer-reviewed scientific papers.The feedback link “Was this Article Helpful” on this page can be used to report content that is not accurate, up-to-date or questionable in any manner. This joint contains a fibrocartilaginous disc, and its surrounded by a synovial membrane and fibrous joint capsule. Wrist joint is second most active joint after ankle joint. The radioulnar joint is often referred to as a joint of the forearm but it is this articulation that gives the wrist more freedom of movement. Its function, apart from increasing stability, is to ensure that the hand follows the forearm during supination. The lunate can also undergo avascular necrosis, so immediate clinical attention to the fracture is needed.The radius fractures, with the distal fragment being displaced This clinical condition produces what is known as the ‘dinner fork deformity’.Try again to score 100%.
