On clinical exam, findings include intense pain on passive supination, pain on palpation of the ECU tendon at the distal ulna, and localized swelling.5, If an acute ECU subluxation/dislocation is not appropriately treated, chronic ECU instability may result. Common symptoms indicative of an extensor carpi ulnaris (ECU) subsheath tear may include: Most commonly, patients may develop this injury through a hard twist or forceful repetitive twists of the wrist. 3 Rettib AC, Patel DV. American Association for Hand Surgery. Mid-term outcome (11-90 months) of the extensor retinaculum flap In rare cases, complete ECU tendon rupture may occur (16a,17a).

Extensor Carpi Ulnaris Subsheath Tears are a fairly common injury involving people who play golf, contact, and racket sports. Lifestyle medicine physician, Andrea Espinoza, MD, FCCP, at OCSM can help. Ulnar sided ruptures of the subsheath, likely the most common pattern of injury, usually result in dislocation followed by reduction in which the tendon returns to a location deep to the subsheath (12a, 13a,13b). This is important when the subsheath is so torn or stretched that the tendon lies partially or completely outside the ulnar groove. The causes of injury were sports injuries in two patients, farming in one patient, an industrial accident in one patient, and unknown reasons in three patients. Coronal T1. On the T1-weighted axial image at the level of the distal ulna, fluid is again noted to surround the ECU tendon (arrow), with irregular longitudinal splitting noted within the tendon.

Lalonde 09:03. it is rare for this to occur passively due to the reduction in tendon tension when the muscle is not contracting. During surgery, the extensor carpi ulnaris (ECU) tendon was replaced back in the normal location on the ulna and secured to the bone with special sutures. Immobilization with a splint or cast in extension and radial deviation is a common treatment.
