Summary
The fabella, a small bone in the knee, can cause peroneal nerve palsy. This study reports seven cases, highlighting diagnostic methods and treatment options for this rare condition.
Area of Science:
- Orthopedics
- Neurology
- Anatomy
Background:
- The fabella is a sesamoid bone within the gastrocnemius muscle tendon.
- Historically, the fabella has been considered to have minimal clinical relevance.
- Its role in causing peroneal nerve palsy has not been widely recognized.
Purpose of the Study:
- To report cases of peroneal nerve palsy attributed to the fabella.
- To describe the clinical presentation of this condition.
- To emphasize the diagnostic utility of electrophysiological tests.
Main Methods:
- Case series reporting seven patients with peroneal nerve palsy.
- Clinical examination and electrophysiological studies (nerve conduction studies, electromyography) were utilized.
- Review of diagnostic findings and treatment outcomes.
Main Results:
- Seven cases of peroneal nerve palsy linked to the fabella were identified.
- Typical clinical features were observed and documented.
- Electrophysiological examinations proved crucial for accurate diagnosis.
Conclusions:
- The fabella can be a cause of peroneal nerve palsy.
- Recognizing the clinical features and utilizing electrodiagnostic tools are essential for diagnosis.
- Treatment may involve surgical or conservative approaches, with three surgical and four conservative interventions reported.
