What is the recommended evaluation and initial management for a patient with a heel injury?

Evaluation and Initial Management of Heel Injury

For a patient presenting with heel injury, begin with weight-bearing radiographs as the initial imaging study, perform a focused physical examination to localize pain and assess for fracture or neurologic involvement, and determine whether immediate orthopedic referral is needed based on fracture displacement, intra-articular involvement, or suspected serious pathology. 1, 2

Immediate Clinical Assessment

History Taking - Key Elements

• Mechanism of injury: Fall from height suggests acute calcaneal fracture (most common osseous cause of traumatic heel pain) 2
• Activity changes: Progressive pain after increased walking or harder surfaces suggests calcaneal stress fracture 2
• Pain characteristics: Burning, tingling, or numbness indicates nerve entrapment requiring different management 2
• Age consideration: In active children/adolescents, calcaneal apophysitis (Sever disease) accounts for up to 16% of musculoskeletal conditions 3

Physical Examination - Specific Maneuvers

• Point tenderness localization: Palpate the Achilles insertion, lateral malleolus, posterior superior calcaneus, lateral calcaneal wall, and calcaneofibular ligament course 1
• Calcaneal squeeze test: Compress the calcaneus medially to laterally—pain is highly suspicious for calcaneal stress fracture 2
• Neurologic assessment: Test for sensory deficits, motor weakness, and perform straight leg raise if radiculopathy suspected 1
• Gait observation: Antalgic gait may indicate more severe pathology 3

Initial Imaging Strategy

First-Line Imaging

• Weight-bearing radiographs of foot and ankle are the mandatory initial study for all heel pain 1, 2
• Standard views should be obtained to confirm or exclude fracture 2

Advanced Imaging - When Indicated

• MRI without contrast or CT without contrast (equivalent alternatives) if radiographs negative but pain persists >1 week 2
• Technetium bone scanning for suspected stress fracture with negative initial radiographs 1, 2
• Lumbar spine MRI if radiculopathy suspected based on examination findings 1

Critical caveat: Calcaneal stress fracture symptoms often occur before the fracture appears on radiographs, so clinical suspicion must guide management even with negative initial imaging 2

Management Algorithm Based on Findings

Immediate Orthopedic Referral Required

• Displaced fracture fragments 4
• Intra-articular fractures involving the subtalar joint (requires surgical management, not casting) 4
• Any concerns about fracture stability on initial or follow-up radiographs 4
• Diffuse rearfoot pain poorly localized suggests subtalar joint involvement 4

Subspecialist Referral for Neurologic Evaluation

• Suspected nerve entrapment with burning, tingling, or numbness 2
• Lumbar radiculopathy (L5-S1 nerve root compression) causing heel-to-hip radiation 1
• Requires electromyography, nerve conduction velocity studies, and MRI 1

Red Flags Requiring Urgent Evaluation

• Constant pain at rest or progressively worsening without mechanical explanation: Consider tumor 2
• Bilateral symptoms, involvement of other joints, or systemic signs: Consider arthritides, infections, or vascular compromise 1
• Suspected osteomyelitis or soft tissue infection: Requires diagnostic testing, consultation, and appropriate referral 2

Common Pitfalls to Avoid

• Never assume isolated plantar fasciitis when pain radiates proximally beyond the heel—this pattern demands neurologic evaluation 1
• Do not miss intra-articular involvement—fractures involving the subtalar joint require surgical management 4
• Never diagnose based on imaging alone—combine symptoms, clinical signs, and imaging findings 1
• Do not delay orthopedic referral for displaced fractures or concerns about fracture stability 4

Conservative Management Considerations

For non-displaced fractures and mechanical causes without red flags, most patients improve with conservative treatment including activity modification, orthotics, and physiotherapy 5, 3. However, surgical management should be reserved for recalcitrant cases or when specific indications (displacement, intra-articular involvement) are present 4, 3.
