ECU Tendon Problems and Ulnar Sided Wrist Pain. ECU subsheath reconstruction +/- wrist arthroscopy, chronic cases may require an extensor retinaculum flap for ECU subsheath reconstruction, Wrist arthroscopy shows concurrent TFCC tears in 50% of cases. Journal of the American Academy of Orthopaedic Surgeons. 2021;22(1):387. doi: 10.1186/s12891-021-04271-z. Depending on the severity of injury, immobilization is necessary for six weeks to three months. Snapping can also be felt, as the misplaced tendon interacts with the bones of the wrist . Graham TJ. Arthroscopic repairs can be . Being mindful of wrist pain during sports activities can prevent extensive damage and tearing of the ECU subsheath. Palpating the ECU groove will likely elicit pain and tenderness for the patient if the ECU is involved in the mechanism of injury. Mid-term outcome (11-90 months) of the extensor retinaculum flap This splint will help prevent the repaired tendons being overstretched. Treating Shoulder Dislocation - UW Orthopaedics and Sports Medicine Pain with subluxation is the critical finding when contemplating surgical treatment. Tendon injuries: basic science and clinical medicine. Following this, the retinaculum was elevated until the extensor carpi ulnaris was identified and it was freed up from surrounding synovium. %PDF-1.5 Orthobullets.com. The patient often can reproduce a painful snap or click with supination and ulnar deviation, even in the absence of ECU subluxation. Localized swelling may be present. Extensor Tendon Repair - LMH It restores stability to shoulders that don't have extensive damage from repeated dislocations. As an injury on the pinky side of the wrist, the extensor carpi ulnaris subsheath becomes torn with sudden, forceful or repetitive rotational movements of the wrist while engaging in sports, though it is more likely to happen in professional athletes, it commonly occurs in weekend athletes, or just when someone falls. Ultrasound: is useful for assessing the dynamic stability of the ECU tendon as the tendon can be visualised whilst the patient/athlete pronates and supinates their forearm. The ECU tendon can be palpated on the dorsal aspect of the wrist with the wrist in resisted extension and ulnar deviation. 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). ecu subluxation surgery recovery time. J Orthop Sports Phys Ther. 2006;40(5):4249; discussion 429. It ensheathes the ECU and maintains the tendon tightly in the groove (. Surgical Intervention Closed reduction of the wrist dislocation can be attempted after a complete neurovascular examination is performed and proper radiographs are obtained. Common symptoms indicative of an extensor carpi ulnaris (ECU) subsheath tear may include: Swelling and discomfort Stiffness Snapping or clicking with rotation Decreased range of motion Causes of Extensor Carpi Ulnaris (ECU) Subsheath Tears
