Pediatric Neurology and Musculoskeletal Disorders for USMLE
This module focuses on key pediatric neurological and musculoskeletal disorders frequently tested on the USMLE. Understanding the pathophysiology, clinical presentation, diagnosis, and management of these conditions is crucial for success.
Pediatric Neurological Disorders
Pediatric neurological disorders encompass a wide range of conditions affecting the brain, spinal cord, and peripheral nerves. Early recognition and intervention are vital for optimizing developmental outcomes.
Cerebral Palsy (CP)
A group of permanent disorders of the development of movement and posture.
Epilepsy
Epilepsy is a chronic neurological disorder characterized by recurrent, unprovoked seizures. In children, it can manifest in various forms, often linked to underlying etiologies such as genetic mutations, structural brain abnormalities, or metabolic disorders.
Neural Tube Defects (NTDs)
Neural Tube Defects are congenital malformations of the central nervous system that occur early in embryonic development. Folic acid supplementation is a key preventive measure.
The development of the neural tube is a complex process. Initially, it forms as a flat plate of ectoderm, which then folds to create a tube. This tube differentiates into the brain and spinal cord. Failure at any stage of this closure process can lead to neural tube defects. The anterior neuropore closes around day 25, and the posterior neuropore closes around day 28 of gestation. Understanding this timeline is crucial for appreciating the timing of potential insults.

Pediatric Musculoskeletal Disorders
Pediatric musculoskeletal disorders affect bones, joints, muscles, and ligaments, impacting a child's mobility, growth, and overall well-being. Early diagnosis and management are key to preventing long-term complications.
Developmental Dysplasia of the Hip (DDH)

Scoliosis
Scoliosis is a lateral curvature of the spine. Idiopathic scoliosis is the most common form, typically presenting during adolescence.
| Feature | Cerebral Palsy | Epilepsy |
|---|---|---|
| Primary Deficit | Motor and postural impairment | Recurrent seizures |
| Etiology | Non-progressive brain injury (prenatal, perinatal, postnatal) | Diverse (genetic, structural, metabolic, unknown) |
| Diagnostic Tools | Clinical exam, neuroimaging (MRI) | EEG, clinical history, neuroimaging (MRI) |
| Management Focus | Therapy (PT, OT, speech), seizure control, spasticity management | Antiepileptic drugs, diet, surgery |
Osteogenesis Imperfecta (OI)
Osteogenesis Imperfecta (OI), also known as brittle bone disease, is a genetic disorder characterized by bones that break easily.
Remember that the USMLE often tests the classic triad of OI: fractures, blue sclerae, and hearing loss.
