Cervical Spine Pathology and Finger Function: Evidence‑Based Recommendations

Pathophysiology of Chronic Compression

• Prolonged severe cervical spinal canal stenosis leads to demyelination of white matter and necrosis of both gray and white matter, creating potentially irreversible neurological deficits. 1

Surgical versus Conservative Management

• Anterior cervical decompression surgery provides superior functional recovery at 12 months—specifically greater improvement in wrist extension, elbow extension, and shoulder abduction—when compared with a regimen of physical therapy alone. 2

Imaging Strategies

• Magnetic resonance imaging (MRI) without contrast is the most sensitive modality for detecting cervical lesions, achieving approximately 88 % accuracy for lesion prediction. 4
• MRI interpretation must be correlated with clinical findings because the study reports frequent false‑negative and false‑positive results, and incidental abnormalities are common in individuals without symptoms. [4][6]

Prognostic Indicators

• Patients presenting with severe and/or long‑lasting cervical symptoms have a low likelihood of meaningful improvement with non‑operative (conservative) measures. 1
• The clinical course often follows a stepwise decline in function over time, although intermittent periods of symptom stability may be observed. 1
