![]() ![]() ![]() May also see tendinosis, muscle edema, tendon thickening, loss of the normal comma shape of the tendon, and juxtacortical edema. MRI may be considered for diagnosis if clinical findings are unclear, will likely show peritendinous edema or fluid surrounding the 1st and 2nd extensor compartments.Radiographs are not necessary for diagnosis.Finkelstein’s Test may be positive, but the area of tenderness should be further proximal from the wrist, oppose to over the first compartment as is seen in DeQuervain tenosynovitis.Compressive neuropathy ("bracelet syndrome").Metacarpophalangeal ulnar ligament rupture (Gamekeeper's thumb).Easily confused with De Quervain tenosynovitisĭifferential Diagnosis Hand and finger injuries Ultrasound Cases Extensor compartment 4 tenosynovitis Extensor tendons dorsal side of the wrist: Fourth compartment Extensor tendons dorsal side of the wrist.Neurovascular evaluation should be normal, and there is usually no associated pain or restriction is proximal joints (elbow, shoulder, neck).Crepitus may be present on active and passive wrist flexion, extension, radial, and ulnar deviation.Unilateral pain where ECRL and ECRB intersect with abductor pollicis longus (APL), extensor pollicis brevis (EPB) - over the dorsum of the wrist on the radial side of the dominant hand, about 5 cm proximal to wrist joint.Relatively uncommon, but has been seen in rowing, baseball, softball, hockey, cycling, golf, skiing, ice climbing and racquet sportsĮxtensor compartments of wrist Clinical Features.Has also been called “Oarsman’s Wrist,” “Bugaboo Forearm,” “Peritendinitis Crepitans,” “Crossover Syndrome,” and “Squeaker’s Wrist.” "Intersection Syndrome" more aptly describes the anatomy involved as this is an inflammatory condition occuring where the abductor pollicis longus and extensor pollicis brevis tendons cross the extensor carpiradialis brevis and extensor carpi radialis longus tendons in the forearm. Located at the intersection of the first and second dorsal compartments of wrist containing extensor carpi radialis brevis and longus (ECRB and ECRL). ![]()
