|July 1, 1984
Summary
Posterior interosseous neuropathy, often caused by elbow injuries or overuse, typically resolves with conservative treatment. This study observed 15 patients, finding electrodiagnostic abnormalities that improved over time.
Area of Science:
- Orthopedic Surgery
- Neurology
- Sports Medicine
Background:
- Posterior interosseous neuropathy (PIN) can result from direct trauma or repetitive activities.
- Understanding the natural history and treatment outcomes of PIN is crucial for patient management.
Purpose of the Study:
- To evaluate the clinical presentation and outcomes of patients with unilateral posterior interosseous neuropathies.
- To determine the effectiveness of conservative management for this condition.
Main Methods:
- Observation of 15 patients diagnosed with unilateral posterior interosseous neuropathy.
- Follow-up of 12 patients for up to five years.
- Electrodiagnostic testing to confirm nerve involvement.
Main Results:
- Seven patients experienced closed elbow injuries; eight had spontaneous onset linked to racquet sports.
- All patients exhibited electrodiagnostic findings indicative of posterior interosseous neuropathy.
- All cases demonstrated positive responses to conservative therapy, with complete resolution.
Conclusions:
- Conservative management is an effective treatment strategy for posterior interosseous neuropathy.
- Posterior interosseous neuropathy, regardless of cause (trauma or overuse), has a favorable prognosis with non-operative care.
