What are the differences in treatment approaches for cervicalgia (cervical pain) versus torticollis (wry neck)?

Cervicalgia vs Torticollis: Key Differences in Treatment Approaches

Cervicalgia (neck pain) is treated primarily with conservative management including NSAIDs and physical therapy, while torticollis (wry neck) requires botulinum toxin injections as first-line therapy for the dystonic muscle contractions, with surgical intervention reserved for refractory cases.

Fundamental Distinction Between Conditions

Cervicalgia (Neck Pain)

• Mechanical pain from facet joints, intervertebral discs, muscles, or fascia represents the majority of nontraumatic cervical pain 1
• Cervical radiculopathy is the primary neuropathic consideration, with an annual incidence of 83 per 100,000 persons 1
• Pain may radiate to upper limbs with or without sensory/motor deficits depending on nerve root involvement 1

Torticollis

• Sustained involuntary muscle contractions causing twisting movements and abnormal head posturing, not simple pain 2
• Presents with specific head positions: rotation (rotatory torticollis), flexion (anterocollis), extension (retrocollis), or lateral tilt (laterocollis) 2
• May be tonic, clonic, or tremulous with potential for permanent fixed contractures 2
• Patients often use sensory tricks (touching chin, back of head) to temporarily ameliorate symptoms 2

Critical Diagnostic Algorithm

For Suspected Cervicalgia

• Screen for red flags immediately: constitutional symptoms (fever, weight loss), elevated inflammatory markers (ESR, CRP, WBC), history of malignancy, immunosuppression, IV drug use, neurological deficits, or vertebral body tenderness 1, 3
• If red flags present: obtain MRI cervical spine without contrast immediately 3, 4
• If no red flags and acute pain (<6 weeks): defer imaging and pursue conservative management 1, 4
• If chronic pain (>12 weeks) without improvement: consider MRI after 6-8 weeks of failed conservative therapy 1, 4

For Suspected Torticollis

• Differentiate muscular from nonmuscular causes: perform complete physical and neurologic examination plus cervical spine radiographs 5, 6
• Acute torticollis: evaluate for trauma (obtain radiographs), infection (otolaryngological or spondylodiscitis), or inflammatory causes 6
• Chronic/recurrent torticollis with neurological abnormalities: CT or MRI necessary to exclude tumoral diseases 6
• Congenital muscular torticollis: MRI of brain and neck is no longer considered cost-effective or necessary 5

Treatment Approaches

Cervicalgia Management

• 75-90% of cervical radiculopathy cases resolve with conservative nonoperative therapy 1, 3
• First-line: NSAIDs, physical therapy, and activity modification 7
• Multimodal approach includes medications for symptom relief, physical therapy for neck discomfort, and guided corticosteroid injections for nerve root pain 8
• Imaging only indicated if red flags present or persistent symptoms beyond 6-8 weeks despite appropriate conservative treatment 1, 4

Torticollis Management

• Botulinum toxin type A (BTX-A) intramuscular injections are the most widely used and accepted therapy for cervical dystonia 2
• Both BTX type A and type B are commercially available for treatment 2
• Mean pain reduction of -1.25 points at 4 weeks after first injection, with 48.1% showing ≥30% pain reduction and responses sustained over five injection cycles 9
• For congenital muscular torticollis: observation and physical therapy (with or without bracing) is effective if instituted within first year of life 5
• Botulinum toxin shown effective as intermediate treatment for resistant congenital muscular torticollis cases 5
• Pharmacotherapy (anticholinergics, dopaminergic agents, muscle relaxants) can be used alone or combined with BTX 2
• Surgery reserved for patients in whom other treatments have failed 2
• Sternocleidomastoid muscle lengthening may be needed for presentations after age 1 year, though this improves range of motion but not necessarily plagiocephaly or facial asymmetry 5

Critical Pitfalls to Avoid

In Cervicalgia

• Do not order imaging immediately without red flags - this leads to overdiagnosis of incidental degenerative changes that correlate poorly with symptoms 4
• Degenerative changes on MRI are present in 53.9% of individuals aged 18-97, with prevalence increasing with age, but association with clinical symptoms remains unclear 1
• Do not interpret MRI findings in isolation - diagnosis requires combination of clinical history, physical examination, and imaging 1

In Torticollis

• Missing nonmuscular torticollis could be life-threatening - must systematically exclude inflammatory, ocular, neurologic, orthopedic, infectious, or tumoral causes 5, 6
• Congenital muscular torticollis is benign, but other etiologies require urgent intervention 5
• Do not assume all neck rotation is dystonic - torticollis may be caused by orthopedic, musculofibrotic, infectious, or structural conditions affecting neck anatomy 2
