Pediatric median mononeuropathies: a clinical and electromyographic study
Muscle & Nerve
|July 1, 1994
Summary
Pediatric median mononeuropathies (PMM) in children present differently than in adults. Causes and locations of PMM in children vary, with a significant portion being proximal and often linked to trauma.
Area of Science:
- Neurology
- Pediatric Neurology
- Electromyography
Background:
- Pediatric median mononeuropathies (PMM) are uncommon in children.
- Understanding PMM in pediatric populations is crucial for accurate diagnosis and management.
- Previous studies have primarily focused on adult median neuropathies, leaving a gap in pediatric-specific data.
Purpose of the Study:
- To characterize the clinical presentation, localization, and etiology of pediatric median mononeuropathies.
- To compare the findings in children with those observed in adult median neuropathies.
Main Methods:
- Retrospective review of 1809 electromyography (EMG) studies performed between 1979 and 1993.
- Identification of pediatric patients (aged 5-17 years) diagnosed with PMM.
- Analysis of PMM localization (proximal vs. distal) and underlying causes.
Main Results:
- Seventeen children were diagnosed with PMM, with 59% presenting as proximal neuropathies.
- Common causes included trauma (8 cases), idiopathic carpal tunnel syndrome (3 cases), and systemic conditions like mucolipidosis III and scleroderma.
- Five children had bilateral PMM, often associated with carpal tunnel syndrome or specific systemic illnesses.
- The etiological profile and localization of PMM in children differed significantly from adult cases.
Conclusions:
- Pediatric median mononeuropathies exhibit distinct characteristics compared to adult presentations.
- Trauma is a significant cause of proximal PMM in children.
- Systemic conditions and idiopathic carpal tunnel syndrome are important considerations in pediatric PMM evaluation.
