Cervical Spine Pathologies and Surgical Interventions

The cervical spine is susceptible to a range of pathologies including degenerative disc disease, osteoarthritic spondylosis, instability at the atlantoaxial and subaxial levels, non-neoplastic retro-odontoid pseudotumours and compressive myelopathy. Clinical presentation varies from axial neck pain and radiculopathy to progressive neurological deficit. Surgical strategies have evolved to address both decompression and stabilisation. Anterior procedures such as cervical discectomy with interbody fusion and disc arthroplasty aim to relieve nerve-root or cord compression while preserving motion. Posterior approaches include laminectomy, laminoplasty and instrumented fusion to achieve indirect decompression or fixation, particularly in cases of multi-level stenosis or structural instability. Minimally invasive instrumentation and image-guided navigation have reduced perioperative morbidity, improved accuracy of implant placement and expedited recovery. Recent advances focus on patient-specific implants, biomaterial optimisation and the identification of imaging biomarkers that predict myelopathic progression. Globally, these interventions have significant impact on quality of life, return to work and long-term neurological function, underscoring the need for multidisciplinary care and continued refinement of surgical techniques.

Research from Nature Portfolio

Recent clinical studies have provided robust data on the benefits of motion-preserving disc arthroplasty in degenerative cervical disc disease. A large prospective cohort demonstrated sustained improvement in neck disability scores and reduced adjacent-segment degeneration at five-year follow-up compared with fusion alone. Parallel imaging research has elucidated the dynamics of retro-odontoid soft tissue following upper cervical fusion, revealing that restoration of atlantoaxial stability leads to consistent regression or disappearance of pseudotumour masses and correlates with neurological recovery. In addition, advanced quantitative MRI techniques have identified microstructural changes in the spinal cord grey and white matter that predict early myelopathy, offering potential for stratifying patients who may benefit most from early surgical intervention.

Cervical Spine Pathologies and Surgical Interventions publication trend

The graph below shows the total number of articles in cervical spine pathologies and surgical interventions across all publications each year (not limited to Nature Index journals).

Technical terms

Atlantoaxial instability: Excessive movement between the atlas (C1) and axis (C2) causing potential spinal cord compression.

Retro-odontoid pseudotumour: A non-neoplastic soft-tissue mass posterior to the odontoid process, often secondary to instability or degenerative change.

Anterior cervical discectomy and fusion (ACDF): Surgical removal of a damaged disc via an anterior approach, followed by interbody grafting and plate-screw fixation.

Laminoplasty: A posterior decompression technique that reshapes and repositions the laminae to enlarge the spinal canal while preserving posterior elements.

Myelopathy: Dysfunction of the spinal cord characterised by motor, sensory or autonomic deficits due to compression or degeneration.

Disc arthroplasty: Replacement of a degenerated cervical disc with an artificial device designed to maintain segmental motion.
