Joints of the hand, X-ray Interphalangeal ligaments and phalanges. Right hand. Deep dissection. Posterior (dorsal) view. The PIP joint exhibits great lateral stability. Its transverse diameter is greater than its antero-posterior diameter and its thick collateral ligaments are tight in all positions during flexion, contrary to those in the metacarpophalangeal joint.
A Jersey finger is a traumatic rupture of the flexor digitorum profundus (FDP) tendon at its point of attachment to the distal phalanx. [4] This injury often occurs in American football when a player grabs another player's jersey with the tips of one or more fingers while that player is pulling or running away. [5]
Flexor digitorum profundus lies deep to the superficialis, but it attaches more distally. Therefore, profundus's tendons go through the tendons of superficialis, and end up attaching to the distal phalanx. For this reason profundus is also called the perforating muscle. [2] The lumbricals of the hand arise from the radial side of its tendons. [2]
This results in either a tear of the tendon or the tendon pulling off a bit of bone. [3] The diagnosis is generally based on symptoms and supported by X-rays. [3] Treatment is generally with a splint that holds the fingertip straight continuously for 8 weeks. [3] The middle joint is allowed to move. [3] This should be begun within a week of the ...
For instance, a splint can be used for certain fractures, soft tissue sprains, tendon injuries, or injuries awaiting orthopedic treatment. A splint may be static, not allowing motion, or dynamic, allowing controlled motion. Splints can also be used to relieve pain in damaged joints. Splints are quick and easy to apply and do not require a ...
Bennett's fracture repair. Though these fractures commonly appear quite subtle or even inconsequential on radiographs, they can result in severe long-term dysfunction of the hand if left untreated. In his original description of this type of fracture in 1882, Bennett stressed the need for early diagnosis and treatment in order to prevent loss ...
A Smith's fracture, is a fracture of the distal radius. [1]Although it can also be caused by a direct blow to the dorsal forearm [2] or by a fall with the wrist flexed, the most common mechanism of injury for Smith's fracture occurs in a palmar fall with the wrist joint slightly dorsiflexed. [3]
Volkmann's contracture results from acute ischaemia and necrosis of the muscle fibres of the flexor group of muscles of the forearm, especially the flexor digitorum profundus and flexor pollicis longus. The muscles become fibrotic and shortened. [citation needed]
