Treatment For Intasubstance Tear Of The Extensor Carpi Ulnaris Tendon

Ulnotriquetral Ligament Split Tear

Scapholunate instability is the most common carpal instability. It may occur after a traumatic extension injury to the wrist or result from repetitive stress, as in chronic crutch walking 65 . Weakness and pain about the dorsal radial aspect of the wrist are frequent complaints. On clinical examination, a positive scaphoid shift test may be found 66 . This result consists of a click elicited when bringing the wrist from ulnar to radial deviation while the scaphoid tuberosity is stabilized by...

Cubital Tunnel Syndrome

Tardy Ulnar Nerve Palsy Mri

Physiologic and compressive cubital tunnel syndromes have been described. Compressive cubital syndrome may have acute, subacute, or chronic presentation. Normal loss in volume and increased pressure within the tunnel during elbow flexion result in physiologic cubital tunnel syndrome. This can be seen in ''sleep palsy,'' as the arm is held in flexion for prolonged periods of time. Blunt trauma to the cubital tunnel is a typical cause of acute external compression syndrome of the ulnar nerve....

Lateral Epicondylitis

Lateral Epicondylitis Mri

Lateral epicondylitis is a pathologic condition of the common extensor tendon at its origin from the lateral epicondyle. Lateral epicondylitis also is known as tennis elbow because more than 50 of tennis players develop the condition at some time or another 36 . Lateral epicondylitis is far more common in Fig. 13. Normal ulnar band of the lateral collateral ligament. Coronal fat-suppressed T2-weighted fast spin-echo image of the elbow shows the normal low signal intensity ulnar band of the...

Ulnar Collateral Ligament Tears

Ucl Tear Mri

Tears of the ulnar collateral ligament may occur following acute valgus stress injury to the elbow or following acute traumatic elbow dislocation 18,19 .Ulnar collateral ligament tears are caused more commonly, however, by chronic repetitive stress to the elbow elicited by sports activities involving overhead throwing 20-23 . Most tears of the ulnar collateral ligament are full-thickness tears that involve the anterior bundle. The vast majority of these full-thickness tears occur in the...

Triceps Tendon Injury

Triceps Tendon Mri

Rupture of the triceps tendon is a rare injury. Triceps tendon rupture occurs in both males and females and in individuals of all ages. Rupture of the triceps tendon is almost always the result of a single traumatic event. The mechanism of injury usually is a fall on an outstretched hand. Less common mechanisms of injury include a direct blow to the posterior elbow and a forceful eccentric contraction of the triceps muscle with the elbow flexed. Most tears of the triceps tendon occur at the...

Normal Mri Rotator Cuff

Mri Labral Tear Anterior

The superior and inferior labra are visualized best on coronal oblique images, whereas the anterior and posterior labra are seen best on axial images Figs. 14 and 15 . A labral tear is diagnosed when an irregular line of fluid or intra-artic-ular contrast tracks into the labral substance or between the labrum and the glenoid articular cartilage Fig. 16 . When a labral tear extends through the joint capsule, a paralabral cyst may develop in an extra-articular location. The cyst may be the most...

Space Occupying Lesion Aberrant Nerve

Carpal Tunnel Syndrome Mri Bowing Ratio

The most common neuropathy of the upper extremity is the carpal tunnel syndrome, with an estimated incidence of nearly 1 annually, or almost 2.8 million new cases per year, and prevalence of 0.125 to 5.8 74 . The syndrome is most often found in patients between 30 and 60 years of age, has a male female ratio of 1 5, and is bilateral in as many as 50 of patients. Clinical complaints include often transient and reversible pain and paresthesia in the median nerve distribution. In wrist flexion, in...
