Gamekeeper's thumb and skier's thumb are two similar conditions, both of which involve insufficiency of the ulnar collateral ligament (UCL) of the thumb. The chief difference between these two conditions is that skier's thumb is generally considered to be an acute condition acquired after a fall or similar abduction injury to the metacarpophalangeal (MCP) joint of the thumb, whereas gamekeeper ...
A Stener lesion is a type of traumatic injury to the thumb. It occurs when the aponeurosis of the adductor pollicis muscle becomes interposed between the ruptured ulnar collateral ligament (UCL) of the thumb and its site of insertion at the base of the proximal phalanx. No longer in contact with its insertion site, the UCL cannot spontaneously ...
The muscle is inserted onto the radial sesamoid bone of the metacarpophalangeal joint. It acts to flex, adduct, and abduct the thumb, and is therefore also able to oppose the thumb. The superficial head is innervated by the median nerve, while the deep head is innervated by the ulnar nerve (C8-T1). [6]
In some particular cases, the entire finger may be subject to amputation. The majority of traumatic injuries are work-related. Today, skilled hand surgeons can sometimes reattach the finger or thumb using microsurgery. Sometimes, traumatic injuries may result in loss of skin, and plastic surgeons may place skin and muscle grafts. [1]
The opponens pollicis causes the thumb to flex and rotate medially, leaving the thumb unable to oppose. Carpal tunnel syndrome can result in thenar muscle paralysis which can then lead to ape hand deformity if left untreated. [11] Ape hand deformity can also be seen in the hand of benediction deformity. [citation needed]
Tendons and ligaments play an active role in maintaining joint stability and controls the limits of joint movements, once injured tendons and ligaments detrimentally impact motor functions. [ 2 ] [ 8 ] Continuous exercise or movement of a musculoskeletal injury can result in chronic inflammation with progression to permanent damage or disability.
Jammed finger is a common term used to describe various types of finger joint injuries. It happens from a forceful impact originating at the tip of the finger directed towards the base. It happens from a forceful impact originating at the tip of the finger directed towards the base.
The ulnar collateral ligament of the thumb runs along the ulnar side of the metacarpo-phalangeal joint of the thumb. The ulnar collateral ligament is an important stabilizer of the thumb. It is on the radial side of the wrist, but on the ulnar side of the thumb. It should not be confused with the ulnar collateral ligament of wrist joint.
