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 ...
Most gamekeeper's thumb partial injuries are treated by simply immobilizing the joint in a thumb spica splint or a modified wrist splint and allowing the ligament to heal. However, near total or total tears of the UCL may require surgery to achieve a satisfactory repair, especially if accompanied by a Stener lesion. [6]
The Latarjet procedure involves the removal and transfer of a section of the coracoid process and its attached muscles to the front of the glenoid. This placement of the coracoid acts as a bone block which, combined with the transferred muscles acting as a strut, prevents further dislocation of the joint. [ 3 ]
It joins with the scapula above at the shoulder joint (or glenohumeral joint) and with the ulna and radius below at the elbow joint. Notice: When the arm is spun so that the thumb point to the outside of the body, meaning the palm of the hand looks forward then it is said the hand is supinated. But when the thumb remains in the inside and the ...
Synovectomy is the surgical removal of the synovial tissue surrounding a joint.This procedure is typically recommended to provide relief from a condition in which the synovial membrane or the joint lining becomes inflamed and irritated and is not controlled by medication alone.
The shoulder joint is considered a ball-and-socket joint. However, in bony terms the 'socket' (the glenoid fossa of the scapula) is quite shallow and small, covering at most only a third of the 'ball' (the head of the humerus). The socket is deepened by the glenoid labrum, stabilizing the shoulder joint. [1] [2]
The coracoacromial ligament may impinge and compress rotator cuff muscle or tendon. [3] It may be damaged during a shoulder injury. [4]The attachment of the coracoacromial ligament may be moved from acromion to the end of the clavicle when reconstructing the acromioclavicular joint.
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.
