Traumatic tears are usually radial or vertical in the meniscus and more likely to produce a moveable fragment that can catch in the knee and therefore require surgical treatment. [citation needed] A meniscus can tear due to an internally or externally rotated knee in a flexed position, with the foot in a flexed position. [5]
Loss of radial inclination is associated with loss of grip strength. [5] Radial length - It is the vertical distance in millimetres between a line tangential to the articular surface of the ulna and a tangential line drawn at the most distal point of radius (radial styloid). Shortening of radial length more than 4mm is associated with wrist ...
Ulnar impaction syndrome is a painful condition of excessive contact and wear between the ulna and the carpus with an associated is a degenerative tear of the TFCC. Positive, neutral, and negative ulnar variance. Relationship between radial length and ulnar variance. Radial length is the measure from distal ulna to radial styloid process.
Rupture can lead to proximal migration of the radius and an apparent lengthening of the ulna at the wrist. Often interosseous membrane tears are associated with adverse impacts on forearm rotation. MRI-assisted diagnosis has been used for mid-substance tears of the interosseous membrane but is expensive and not widely available.
The radial collateral ligament (external lateral ligament, radial carpal collateral ligament) extends from the tip of the styloid process of the radius and attaches to the radial side of the scaphoid (formerly navicular bone of the hand), immediately adjacent to its proximal articular surface and some fibres extend to the lateral side of the trapezium (greater multangular bone).
When a tear occurs in this area of the TFC, it typically creates an unstable flap of tissue that is likely to catch on other joint surfaces. Removing the damaged tissue (debridement) is then indicated. Arthroscopic debridement as a treatment for degenerative TFC tears associated with positive ulnar variance, unfortunately, show poor results ...
A SLAP tear or SLAP lesion is an injury to the superior glenoid labrum (fibrocartilaginous rim attached around the margin of the glenoid cavity in the shoulder blade) that initiates in the back of the labrum and stretches toward the front into the attachment point of the long head of the biceps tendon.
A biceps tendon rupture or bicep tear is a complete or partial rupture of a tendon of the biceps brachii muscle. It can affect any of the three biceps brachii tendons - the proximal tendon of the short head of the muscle belly, the proximal tendon of the long head of the muscle belly, or the distal tendon. The characteristic finding of a biceps ...
