The ECU lies in its own separate fibro-osseous subsheath, which represents a duplication of the infratendinous retinaculum. New patients can schedule an appointment online and fill out your patient information to save time. Being mindful of wrist pain during sports activities can prevent extensive damage and tearing of the ECU subsheath. 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. The triangular fibrocartilage complex (TFCC) is a network of ligaments, tendons, and cartilage that sits between the ulna and radius bones on the small finger side of the wrist. Extensor Carpi Ulnaris (ECU) Subluxation Introduction Extensor Carpi Ulnaris (ECU) muscle primary functions at the wrist joint is to move the joint into extension and ulnar deviations whilst also providing a stabilising force at the ulnar side of the joint. These positions increase the angulation of the ECU tendon relative to the ulna and result in maximal force upon the ECU subsheath.6 The most commonly reported sporting activities resulting in ECU subluxation or dislocation are tennis and golf. Jonathan Cluett, MD, is a board-certified orthopedic surgeon with subspecialty training in sports medicine and arthroscopic surgery. A splint has been used to maintain the arm in position, to allow the tendon to heal without dislocating. [cited 2021 Nov 28]. This procedure is completed as an outpatient under awake, regional block anesthesia, which allows patients to return home the day of their surgery to continue recovery there. The displacement of the tendon is also often visible upon physical examination of the injured area. Patients present with complaints of pain, swelling, and stiffness. Labral repair or capsulorraphy are an elective outpatient procedure that can be scheduled when circumstances are optimal. Due to the mobility required around the wrist the muscle relies on specific stabilising structures such as the fibro-osseous groove, tendon subsheath and extensor retinaculum to maintain its position at the wrist[1]. It is normal to have some pain off and on for approximately one year after surgery, particularly in cold weather. A positive ECU synergy test appears sensitive although not 100% specific for ECU tendinopathy. Surgery can also be used to repair or remove damaged tissue that contributes to subluxation. The supratendinous retinaculum participates as a block to tendon subluxation for the first through fifth extensor compartments but does not function to prevent subluxation of the ECU. J Hand Surg 2001; 26(6): 556-559. Yaw Boachie-Adjei, MD, is a board-certified, double-fellowship Orthopedic Surgeon. Dallas Fort-Worth accessible hand and wrist offices. Of course, a physical examination is both the simplest and often most effective in determining if you are suffering from ECU subluxation, because the subluxing ligament inherent in the condition can be felt and often seen by the naked eye. Recovery and rehabilitation Before you leave hospital, a hand therapist may replace the rigid plaster splint (a support designed to protect the hand) fitted during the operation with a lighter and more flexible plastic one. The ECU sheath is separated from the supratendinous retinaculum by loose areolar tissue. The literature does not agree on the efficacy of nonoperative treatment. At the level of the proximal carpal row, the ECU tendon (arrow) is severely thickened and demonstrates increased signal intensity throughout its substance, compatible with severe tendinosis. Modification of the activities that led to the condition in the first place can also be an important way to avoiding the escalation of symptoms, which usually means stepping back from the athletic hobby that caused it. Following surgery, the wrist is casted in extension for a minimum of four weeks. In the elite basketball setting, acute tendonitis and ECU injury can occur after a single forceful wrist flexion/ulnar deviation . Extensor Carpi Ulnaris (ECU) muscle primary functions at the wrist joint is to move the joint into extension and ulnar deviations whilst also providing a stabilising force at the ulnar side of the joint. Surgery of the Hand assh.org The Best Resource For Your Hands, Period. ECU subluxation or dislocation of the tendon happens when that sheath tears or stretches and the tendon itself becomes dislocated from the bone.

What is the most common cause of ECU subluxation? it is rare for this to occur passively due to the reduction in tendon tension when the muscle is not contracting.

Extensor carpi ulnaris (ECU) tendon dislocation or subluxation can be one cause of ulnar-sided wrist pain. 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. Diagnosing Bursitis & Tendonitis in Adults. This may best be demonstrated during the physical exam. X-rays would be normal for most patients with tendonitis. The ECU subsheath is torn at its radial attachment (arrow). Surgical Intervention Closed reduction of the wrist dislocation can be attempted after a complete neurovascular examination is performed and proper radiographs are obtained. In order to determine the full extent of the injury to the sheath and to ascertain the exact position of the ECU tendon, MRI or ultrasound imaging are used to look inside the wrist and locate all of the relevant body parts. Also known as arthroscopic labral repair, this common procedure repairs tears to the labrum -- the ring of cartilage around the edge of your shoulder socket. Although repetitive stress likely precedes injuries to the ECU subsheath, most patients who experience subluxation or dislocation of the ECU recall a traumatic event, typically occurring during supination, ulnar deviation, and wrist flexion.

You have very little use of the operative arm for about 8 weeks after surgery, until the tissue heals. The tendon itself, passes under the extensor retinaculum within a synovial sheath that forms the 6th compartment of the wrist, within a grove lateral to the ulna styloid process. What is the ECU? This immobilization time is approximately two to three weeks. In this case, the intraoperative findings showed the edges of the ruptured subsheath to be separated by a minimum of 7 mm, regardless of the position of the wrist. If the addition of ECU contraction is required for frank dislocation, some inherent stability remains. Normally, the lens of your eye is clear.

Injuries to the extensor carpi ulnaris (ECU) are a well recognized but often poorly understood cause of such pain. In less serious cases, a splint or cast can be used to hold the wrist immobile while the damaged tendon sheath repairs itself, but if there is a more serious injury to the sheath, or even a rupture, then medical or even surgical intervention may be necessary in order to address the condition properly.

Taking medication can make you sleepy and delay your reaction time. In rare cases, complete ECU tendon rupture may occur (16a,17a). Pronator Syndrome (Now called . A complete physical examination of the patients ulnar-sided wrist complaints should be conducted to elucidate associated pathology and rule out confounding conditions in the differential diagnosis. Tendinopathy: is imaging telling us the entire story? Ultimately, increasing pain limits wrist activity, and subsequent imaging reveals the tendon rupture. The overall incidence of wrist injury can be up to 8.9% of all reported sports injuries but data documenting the frequencing of ECU subluxations specifically is limited[2]. On average, lateral release procedure is the quickest to recover from, and a bone realignment surgery takes the longest to recover from. 50% of surgical cases also find a TFCC tear. Treatment Conservative treatment: Munster splint to prevent forearm rotation = rest load management and isometric exercises US guided cortisone injection More common in patients with ulnar positive variance, Usually a dynamic phenomenon occurring during forceful activity or pronated gripping.
