Understanding Cervical Spondylosis —
Finding the Source

Cervical spondylosis is a radiological description of degenerative changes in the cervical spine — disc space narrowing, osteophyte formation, and facet joint arthropathy. It is an extremely common finding on imaging: detectable in the majority of adults over 50 and in a significant proportion of people in their 30s and 40s without any symptoms. The diagnosis by itself does not explain pain, does not predict the severity of symptoms, and does not determine the treatment — the clinical presentation determines all of these.

The clinically important questions are: which syndrome does the patient have (axial pain, radiculopathy, or myelopathy)? Which level is clinically responsible? What is the degree of neurological involvement? Is there any cord compromise? A patient with 'severe' spondylosis on MRI may be asymptomatic; a patient with 'mild' spondylosis may have significant radiculopathy if a small disc herniation has compressed a nerve root in a narrow foramen. ROOT METHOD's assessment reads the clinical story to answer these questions — not just the imaging report.

Cervical radiculopathy is a clinical syndrome produced by compression or irritation of a cervical nerve root — most commonly by a herniated disc or osteophyte encroaching on the intervertebral foramen. It produces pain, paraesthesia (tingling or numbness), and weakness in the distribution of the affected nerve root. The specific level is identified by the dermatomal distribution of sensory symptoms and the pattern of motor weakness and reflex change. C5, C6, and C7 radiculopathies are the most common, corresponding to the most frequently degenerated C4-C5, C5-C6, and C6-C7 disc levels.

The natural history of cervical radiculopathy is generally favourable — the majority of patients improve significantly within 4–6 weeks with appropriate conservative management, and over 90% achieve good outcomes within 2–3 months without surgery. Conservative management includes targeted neural mobilisation, cervical traction (where appropriate), activity modification, and structured progressive neck rehabilitation. Surgical decompression is reserved for patients with progressive neurological deficit (worsening weakness), intractable pain despite adequate conservative treatment, or the rare presentation of acute myelopathy.

Cervical myelopathy is compression of the spinal cord itself — the most serious consequence of advanced cervical spondylosis. When degenerative osteophytes, disc herniation, or ligamentum flavum hypertrophy reduce the spinal canal diameter sufficiently to impinge on the cord, the cord's ascending and descending tracts become dysfunctional, producing the characteristic myelopathic clinical picture: bilateral arm numbness and clumsiness, gait disturbance with unsteadiness, difficulty with fine motor tasks, and in advanced cases, lower limb weakness and bladder dysfunction.

Myelopathy is serious because unlike radiculopathy — which produces reversible nerve root dysfunction in most cases — spinal cord compression, if left untreated, produces progressive and potentially irreversible cord damage. The natural history of symptomatic myelopathy is stepwise deterioration, not spontaneous recovery. Surgical decompression — typically anterior cervical discectomy and fusion or posterior laminectomy — is the primary treatment and aims to prevent further deterioration and allow partial neurological recovery. The earlier decompression is performed, the greater the likelihood of meaningful neurological improvement. Myelopathy identified at ROOT METHOD assessment is referred urgently to neurosurgical assessment without delay.

Not necessarily — and this is one of the most important clinical distinctions in cervical spine management. MRI findings of spondylosis, disc herniation, and foraminal narrowing are common in the population and do not reliably predict symptoms without a corresponding clinical examination. A large disc herniation at C5-C6 on MRI is clinically significant only if the clinical examination demonstrates C6 dermatomal sensory loss, reduced brachioradialis reflex, and pain provoked by Spurling's manoeuvre at that level. The same finding in the absence of these clinical correlates may be entirely incidental.

The risk of treating imaging findings rather than clinical findings is significant: unnecessary intervention, treatment directed at the wrong level, and prolonged management of an incidental finding while the true pain generator remains unidentified. ROOT METHOD's approach is to review imaging only after a thorough clinical assessment has identified the likely responsible level — then to confirm whether the imaging findings at that level are consistent with the clinical picture. This sequence prevents the imaging from driving the clinical interpretation rather than informing it.

The large majority of cervical spondylosis — including most cases of cervical radiculopathy — responds well to conservative management and does not require surgical intervention. The evidence supports structured conservative management as the first-line approach for cervical spondylotic neck pain and radiculopathy: targeted cervical mobility exercises, deep cervical flexor strengthening, postural correction, neural mobilisation for radiculopathy, and — where indicated — cervical traction and well-timed injection therapy. In studies of cervical radiculopathy, 75–90% of patients achieve satisfactory outcomes with conservative treatment within 3 months.

Surgical indication is reserved for specific circumstances: progressive neurological deficit from radiculopathy (worsening weakness), radiculopathy with intractable pain unresponsive to comprehensive conservative treatment, and — most importantly — any degree of myelopathy (cord compression). Myelopathy is not managed conservatively. For the axial spondylotic pain and radiculopathy presentations, ROOT METHOD's conservative management protocol is structured, progressive, and criterion-based — specifying when injection referral and when surgical assessment is warranted based on the trajectory of clinical response.

Several conditions produce arm pain and sensory disturbance that can be confused with cervical radiculopathy: peripheral nerve entrapment (carpal tunnel syndrome, cubital tunnel syndrome, thoracic outlet syndrome), shoulder pathology with referred arm pain, and complex regional pain syndrome. The key distinguishing features of true cervical radiculopathy are: dermatomal distribution of sensory symptoms corresponding to a specific nerve root territory; myotomal motor weakness in the muscles supplied by that root; corresponding reflex depression; reproduction of symptoms by Spurling's test (extension-rotation loading the affected foramen); and relief of symptoms with cervical distraction.

Double crush syndrome — where a nerve root is compressed at the cervical level AND the same nerve is compressed peripherally (e.g. C6 radiculopathy with coexisting carpal tunnel syndrome) — is an important clinical entity that explains why some radiculopathy patients fail to fully recover after cervical treatment alone. ROOT METHOD's upper limb neurodynamic testing (ULNT1, ULNT2a, ULNT2b) sensitises the peripheral nerve mechanically to identify both cervical and peripheral sites of neural tension — allowing both levels to be addressed in the management protocol when they coexist.
