Brief Summary

Lateral epicondylosis, also called tennis elbow or lateral epicondylitis, is a prevalent, painful syndrome of the elbow. It is refractory to conservative treatment measures, including rest, excentric and concentric exercises in approximately 20% of patients after 6 months. Corticosteroid injections can provide relief in the short term. Mini-open surgery may be proposed when the conservative treatment fails and studies have shown an efficacy of 70%. Ultrasound-guided tendon fenestration is a minimally-invasive technique which stimulates the physiological healing mechanisms of the tendon and appears promising for the treatment of chronic tendinopathies. To our knowledge, no studies have compared the US-guided fenestration technique to mini-open surgery for the treatment of chronic lateral epicondylosis. The primary objective of this pilot study is to compare the efficacy of US-guided fenestration to mini-open surgery to reduce pain and improve functional status in workers suffering from chronic lateral epicondylosis refractory to 6-month conservative treatment. This is a prospective single-blind randomized pilot study. Sixty-four subjects will be randomized into two intervention groups for treatment either by US-guided fenestration or mini-open surgery. The primary outcome of the study will be the Patient Rated Tennis Elbow Evaluation (PRTEE) score at 6 month post-procedure.

Procedure: Mini-open surgery

EXPERIMENTAL

Tendon fenestration

Device: Ultrasound-guided Tendon fenestration

Interventions

This treatment will be administered by an orthopedic surgeon specialized in upper limb surgery. 1. Skin disinfection; Local anesthesia (lidocaine 1%). 2. Skin incision, slightly anterior to lateral epicondyle. 3. Exposure of the plane between the tendon and fascia. 4. Extensor Carpi Radialis Longus (ECRL) tendon is lifted to expose the Extensor Carpi Radialis Brevis (ECRB) tendon. 5. Excision of diseased tissue of the ECRB tendon. 6. ECRL tendon is sutured back to the fascia. The skin is closed. 7. Patient is monitored for 30 minutes after procedure.

Mini-open surgery

This treatment will be administered by a fellowship-trained MSK radiologist. 1. Patient's elbow at 70 degrees of flexion with the forearm pronated resting on an examination table. 2. Skin disinfection. Local anesthesia, skin, superficial fascia and tendon, with lidocaine 1%. 3. Using a 22 G needle under continuous ultrasound guidance, several passes (about 20-30) within the abnormal area of the tendon, contacting the bone, until the area softens. 4. Patient monitored for 30 minutes, before being discharged.

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Workers
  • Ability to read, understand and answer questionnaires in French or English
  • Diagnosis of unilateral, lateral epicondylosis established by an orthopaedist, determined by clinical presentation and pain, ≥ 4/10 on a pain numerical rating scale, on palpation of the region slightly anterior and distal to the lateral epicondyle, exacerbated by the extension of the wrist or the middle finger when the elbow is in extension.
  • Chronic epicondylosis, refractory to medical treatment conducted for at least six months, which includes rest and implementation of ergonomics to avoid soliciting the extensor tendons, and at least one of: physical therapy, a rehabilitation program with stretching and / or strengthening exercises, injection treatments (corticosteroids, autologous PRP) or extracorporeal shock waves.

You may not qualify if:

  • Suspected tumor or infectious etiology
  • Injection of corticosteroids during the last 3 months
  • Hemorrhagic diathesis; anticoagulation (platelets \<50,000, International Normalized Ratio (INR) \> 2)
  • Local infection
  • History of elbow surgery or fracture
  • History of inflammatory arthropathy
  • Neck pain and radiculopathy
  • Inability to provide informed consent because of a language problem, dementia or a major psychiatric disorder.
