Great advances have occurred in imaging techniques; however, these imaging techniques, though often invaluable, can be expensive and may prove unnecessary with a thorough physical examination and a. AAROM/AROM exercises: consider taping ECU during this time to help maintain tendon stability, Rotator cuff strength and endurance exercises, Isometric -> isotonic wrist strengthening exercises, Including review of equipment (eg tennis racket grip -> greater risk of injury with a western or semi-western style of grip due to the high amounts of top spin generated). In addition, the ECU was subluxated volarly in forearm supination with tendon attrition at the level of the ulnar The fibro-osseous subsheath of the sixth dorsal compartment overlies 1.5 to 2.0 cm of the distal ulna and arcs from the radial to ulnar wall of the ECU osseous groove. Surgical reconstruction of the ECU subsheath should be considered in patients with clinically significant symptoms related to painful subluxation of the ECU tendon, especially if the injury is more than 3 weeks old.

We encountered a case of ECU dislocation combined with extensor tendon subluxation of the long finger at the metacarpophalangeal (MP) joint. The physical examination findings will be similar to those of TFCC injury, with pain on forced ulnar deviation of the wrist (TFCC stress test) that increases with rotation through the loaded ulnocarpal articulation. distal ulnar resection (Wafer procedure) preserve ulnar attachment of TFCC.

ECU is the standard medical acronym for Extensor Carpi Ulnaris, which is the muscle/tendon that runs along the outside of the upper side of the hand and is integral in the extension of the carpal bones, as its name implies. It is also important for athletes, or individuals who use a lot of repetitive movements as a part of their job, to learn proper form and techniques to help avoid injury in the long-run.
