Resting the arm during sports activities can aid in the prevention of substantial tears. 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. The ECU subsheath (arrowheads) is diffusely thickened and irregular and marked tenosynovitis is present. Tenderness on palpation of the 6th dorsal compartment and the ECU tendon will localise the are of discomfort. Read Disclaimer.

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. This usually sits the tendon back within the ulnar groove. When an individual experiences an ECU subsheath tear, they may become more prone to further injury of the wrist and may have sustained additional damage that often occurs during the same injury. The tendon sits in the ulnar groove and may encounter subluxation, dislocation or rupture with or without ulnar sided wrist pain. If it's either a tear or over-stretching, you could still deal with it conservatively. Erpala F, Ozturk T. Snapping of the extensor carpi ulnaris tendon in asymptomatic population.

Diagnosis is made with clinical examination with palpation of the ECU tendon and noting a painful snap while moving the wrist from pronation to supination. When refering to evidence in academic writing, you should always try to reference the primary (original) source. The tendon is subluxed into the pouch formed by stripping of the subsheath and/or periosteum at its palmar attachment. Chronic subluxation of the ECU tendon over the ulnar prominence of the groove in the distal ulna can lead to painful snapping of the tendon with supination and pronation. A STIR axial image reveals fluid (arrowheads) surrounding the ECU tendon at the distal ulna, compatible with tenosynovitis. Small amounts of adjacent edema and fluid are evident on the STIR image. The tendon itself lies within a bony groove along the dorsal, distal ulna. Surgical Treatment for Extensor Carpi Ulnaris Subluxation [Internet]. Kim et al. Synovectomy: Removal of inflamed synovial tissue (membrane surrounding inflamed joints) to alleviate RA symptoms. Disruption can result in static instability of the DRUJ. In contrast the prevalence of ECU injuries specifically within golf, has been poorly recognised although it is acknowledged that the wrist is frequently injured in both amateur and professional golfers[1]. Chiropractic care: Another nonsurgical treatment option. The average time interval between symptom onset and surgery was 13 months (range, 3-36 months). J Orthop Sports Phys Ther. Middorsal wrist injuries that are misdiagnosed can delay return to play. The extensor carpi ulnaris (ECU) tendon is involved in many pathologies seen in golf, hockey, tennis, and baseball athletes. Recovery can take 3 months or more. 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. Common risk factors for ECU injury are[1]: Acute injuries are commonly associated with some form of 'trauma' that requires high levels of wrist extensor or ulnar deviation forces to be produced, such as: An athlete/patient may report that they felp a "snap", "pop" or a "tear" at the time of the trauma. Epidemiology of elbow, forearm, and wrist injuries in the athlete.

Journal of the American Academy of Orthopaedic Surgeons. Dr. Knight welcomes you to any of our Dallas Fort-Worth accessible hand and wrist offices. Br J Sports Med. Curr Rev Musculoskelet Med. This can progress to ECU tendinopathy and partial tendon tears. Magnetic resonance imaging and ultrasounds are often employed to diagnose or confirm subsheath tears. MPFL reconstruction is a surgery in which a new medial patellofemoral ligament is created to stabilize the knee and help protect the joint from additional damage. 2006;40(5):4249; discussion 429. This is important when the subsheath is so torn or stretched that the tendon lies partially or completely outside the ulnar groove. The mechanism of a traumatic injury most commonly involves active ECU contraction combined with forced supination, palmar flexion, and ulnar deviation. In my case (where I had both ECU subluxation AND carpal instability), I decided to limit the movement in my wrists. By Jonathan Cluett, MD Associated patchy area of bone marrow edema is seen involving the ulnar styloid process evoking a high STIR signal. More common in patients with ulnar positive variance, Usually a dynamic phenomenon occurring during forceful activity or pronated gripping. Routine anteroposterior (AP), lateral, and oblique radiographs in neutral rotation are important. Ulnar sided wrist pain is a common clinical complaint and indication for MR imaging.

The overlying extensor retinaculum (blue) courses over the ECU and distal ulna to attach to the pisiform and triquetrum. Full recovery with return to sports at about 6 months after surgery. The ECU tendon demonstrates mild palmar subluxation, and the palmar attachment of the subsheath (arrowhead) is stripped and therefore lies more palmar than is typical. Following this, the retinaculum was elevated until the extensor carpi ulnaris was identified and it was freed up from surrounding synovium. (1a) Gradient echo coronal, (1b) T1-weighted axial, and (1c) STIR axial images of the wrist are provided. A STIR axial image reveals a dislocated ECU tendon (asterisk). Treatment must be individualized based on the needs and expectations of the patient. Patients underwent ECU subsheath reconstruction at a median of 5.9 weeks after diagnosis (IQR 2.4-13).

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. 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. 2021;22(1):387. doi: 10.1186/s12891-021-04271-z, Adams J, Habbu R.
