What is the appropriate ROS (Review of Systems) and management for an 11-year-old male presenting with leg pain and dragging his feet?

Review of Systems and Management for an 11-Year-Old with Leg Pain and Foot Dragging

A comprehensive neurological and musculoskeletal review of systems is essential for an 11-year-old presenting with leg pain and foot dragging, with particular focus on ruling out restless legs syndrome, peripheral arterial disease, and neurological conditions.

Initial Assessment

Focused History

• Pain characteristics:
  • Location: Determine if localized to specific area (hip, thigh, calf, foot)
  • Quality: Aching, burning, cramping, or sharp
  • Timing: Worse at night (suggests restless legs syndrome) or with activity (suggests claudication)
  • Duration: Acute vs. chronic
  • Exacerbating/relieving factors: Does movement help or worsen symptoms?
  • Associated symptoms: Numbness, tingling, weakness

Key ROS Components

1. Neurological system:

   • Sensory changes: Numbness, tingling, or paresthesias
   • Motor function: Weakness, coordination issues, or balance problems
   • Urinary/bowel function: Any changes suggesting spinal pathology 1
   • Sleep patterns: Difficulty sleeping due to leg discomfort 1

2. Musculoskeletal system:

   • Joint pain or swelling
   • Muscle weakness or atrophy
   • Gait abnormalities beyond foot dragging
   • Back pain (may indicate spinal pathology)
   • History of trauma or overuse 1

3. Vascular system:

   • Claudication symptoms
   • Color changes in extremities
   • Temperature differences between limbs 1

4. Systemic review:

   • Fever or recent illness
   • Weight changes
   • Fatigue
   • Family history of neurological or musculoskeletal disorders 1

Physical Examination

Essential Components

1. Neurological examination:

   • Strength testing of lower extremity muscle groups
   • Deep tendon reflexes (patellar and Achilles)
   • Sensory testing (light touch, vibration, proprioception)
   • Gait assessment including toe and heel walking 1

2. Musculoskeletal examination:

   • Inspection for asymmetry, atrophy, or deformity
   • Palpation for tenderness along bones, joints, and muscles
   • Range of motion testing of hips, knees, ankles
   • Spine examination for scoliosis and other abnormalities 1
   • Assessment for joint hypermobility (Beighton score) 2

3. Vascular examination:

   • Pulse assessment (femoral, popliteal, dorsalis pedis, posterior tibial)
   • Capillary refill
   • Skin temperature and color 1

Diagnostic Approach

Initial Testing

1. Laboratory studies:

   • Complete blood count
   • Inflammatory markers (ESR, CRP)
   • Vitamin D level (hypovitaminosis D is common in children with leg pain) 2
   • Iron studies (to rule out iron deficiency) 2
   • Consider calcium and magnesium levels if hypocalcemic cramping suspected 1

2. Imaging:

   • Plain radiographs of the affected limb(s) to evaluate for fractures or bone abnormalities 1
   • Consider spine radiographs if back pain or neurological symptoms are present 1

Advanced Testing (Based on Initial Findings)

1. MRI:

   • Indicated for persistent symptoms with normal radiographs
   • Particularly useful for soft tissue, cartilage, and bone marrow pathology 1

2. Nerve conduction studies/EMG:

   • If peripheral neuropathy or radiculopathy is suspected 3

3. Sleep study:

   • If restless legs syndrome is suspected based on diagnostic criteria 1

Management Algorithm

Step 1: Rule Out Serious Pathology

• If signs of infection: Initiate appropriate antibiotics and further workup
• If evidence of fracture: Orthopedic referral
• If neurological deficits: Urgent neurological consultation

Step 2: Assess for Specific Conditions

If Restless Legs Syndrome Suspected:

Diagnostic criteria (all must be met) 1:

1. Urge to move legs with uncomfortable sensations
2. Symptoms begin/worsen during rest/inactivity
3. Symptoms relieved by movement
4. Symptoms worse in evening/night

Management:

• Optimize iron status if deficient
• Consider referral to pediatric neurologist or sleep specialist
• Evaluate for underlying causes

If Musculoskeletal Pain:

• For non-specific leg pain with increased joint mobility (common finding) 2:
  • Physical therapy focusing on strengthening exercises
  • Proper footwear with arch support
  • Consider orthotic devices if pes planovalgus present 1

If Neurological Issue:

• For signs of peripheral neuropathy:

  • Referral to pediatric neurologist
  • Consider medications for neuropathic pain if appropriate 3

• For signs of spinal pathology:

  • MRI of spine to rule out tethered cord or other abnormalities 1
  • Neurosurgical consultation if structural abnormalities identified

Special Considerations

Common Pitfalls

1. Missing serious pathology:

   • Always consider spinal cord pathology in children with gait abnormalities
   • Don't attribute symptoms to "growing pains" without thorough evaluation

2. Overlooking non-musculoskeletal causes:

   • Consider metabolic, neurological, and vascular etiologies
   • Remember that hip pathology can present as knee or thigh pain 1

3. Inadequate follow-up:

   • Schedule regular reassessment if symptoms persist
   • Consider referral to appropriate specialist if not improving with initial management

Conclusion

For an 11-year-old with leg pain and foot dragging, a thorough neurological and musculoskeletal review of systems followed by targeted physical examination is essential for accurate diagnosis and management. The combination of increased joint mobility and ankle dorsiflexion strength has been found to be predictive of leg pain in children 2, but serious neurological conditions must be ruled out when foot dragging is present. Early intervention with appropriate referrals can prevent long-term complications and improve quality of life.
