Avulsion of the triceps tendon
Clinical Orthopaedics and Related Research
|November 1, 1981
Summary
Triceps tendon avulsion presents with elbow pain after upper extremity deceleration stress. Differentiating complete from partial tears via elbow motion assessment is crucial for appropriate treatment, with surgery recommended for complete tears.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Musculoskeletal Radiology
Background:
- Triceps tendon avulsion is a potential injury following deceleration stress to the upper extremity.
- It can occur with or without direct trauma to the posterior arm.
- Patients present with pain, swelling, and a palpable defect near the olecranon.
Observation:
- Roentgenograms may reveal avulsed osseous fragments.
- Distinguishing between complete and partial triceps tendon tears is critical for management.
- Active range of motion and resisted extension are key examination components.
Findings:
- Partial tears, characterized by normal elbow motion and extension against resistance on follow-up, may be managed nonoperatively.
- Complete avulsions necessitate surgical intervention.
- Surgical repair using heavy nonabsorbable sutures through olecranon drill holes has shown success.
Implications:
- The incidence of tendon avulsion and rupture may increase with the growing population of patients with chronic kidney disease undergoing dialysis.
- Tendo-osseous weakness and musculoskeletal disorders in patients with renal osteodystrophy remain significant challenges.
