Osteochondrosis of the spine: symptoms, diagnosis and treatment

Spinal osteochondrosis is a common term used in practice to describe a wide range of degenerative changes in the discs and joints of the spine: from intervertebral osteochondral remodeling to protrusions, disc herniations, and spondylosis. The International Classification of Diseases, 10th revision, identifies "spinal osteochondrosis" as a separate code, M42, but modern clinical practice and ICD-11 often use more precise formulations: "degenerative spinal disease," "intervertebral disc degeneration," "spondylosis," "spinal stenosis," etc. This facilitates more accurate treatment planning and prognosis. [1]

Back and neck pain are the most common reasons for doctor visits and missed work worldwide. According to the World Health Organization, 619 million people experienced low back pain in 2020, and by 2050, this number is expected to rise to 843 million. Back pain is the leading cause of disability globally. These figures highlight that "osteochondrosis" is not a "destiny" or a "salt deposit," but a common yet manageable condition that requires competent diagnosis and personalized care. [2]

The way we talk about this problem is changing: we rely less on the "picture" on a CT scan and more on the combination of symptoms, neurological status, red flags, and the impact of pain on everyday life. Consider: significant changes on an MRI may be completely painless, while moderate findings in another patient may produce dramatic symptoms. This is why current guidelines encourage a balanced use of imaging and a focus on proven treatment methods with an emphasis on active recovery. [3]

The purpose of this article is to provide an updated, popular, yet accurate picture: from ICD-10 and ICD-11 codes and epidemiology to causes, pathogenesis, diagnosis, differential diagnosis, and modern treatment approaches, including new methods. The text is designed for patients and interested readers: complex concepts are explained in simple language, but with reference to primary sources.

Code according to ICD-10 and ICD-11

ICD-10 retains the traditional concept of "spinal osteochondrosis" and codes it in block M42 with age-specific and unspecified variants. In practice, when it is necessary to record a specific clinical problem (for example, a herniated disc with radiculopathy), codes M50-M51 ("intervertebral disc lesions") or M47 ("spondylosis") are often used. The choice of code depends on the predominant clinical syndrome and examination data. [4]

ICD-11 has moved away from the term “spinal osteochondrosis” as a single label and groups conditions into the FA80-FA8Z “Degenerative disease of the spine” block: “degeneration of the intervertebral disc” with detailed subcategories by sections and complications, spondylolysis, stenosis, spondylolisthesis, endplate defects, etc. In addition to the “structural” code, ICD-11 separately takes into account the pain syndrome (for example, “chronic primary low back pain” MG30.02) - this helps to simultaneously describe both the morphology and the clinical picture. [5]

Table 1. Comparison of codes (summary)

Topic	ICD-10 (examples)	ICD-11 (examples)
Osteochondrosis of the spine	M42 (M42.0 juvenile, M42.1 adult, M42.9 unspecified)	The term is not used as a heading; see "Degenerative spinal disease"
Disc degeneration	M50-M51	FA80 (subsections by departments and complications)
Spondylosis/other spondylopathies	M47, M48	FA82 (stenosis), FA84 (spondylolisthesis), FA8Y/FA8Z (other/unspecified)
Pain as a diagnosis	M54 (dorsalgia)	MG30.02 "Chronic primary low back pain"; MG30.3 "Chronic secondary musculoskeletal pain" [6]

Epidemiology

Low back pain is a global phenomenon: 619 million people (approximately 1 in 13) lived with it in 2020, and 843 million are expected to by 2050. It is the most common cause of years of life lost with disability. Neck pain, however, remains the second most common cause of musculoskeletal pain, with an age-standardized prevalence of over 3,500 cases per 100,000 population in 2017. [7]

Structural signs of "osteochondrosis" on imaging are common and increase with age, even in people without pain: a systematic review found that MRI evidence of disc degeneration is found in 37% of 20-year-olds and 96% of 80-year-olds. This is an important caveat: "image" does not equal disease, and clinical decisions should be based on symptoms and neurological status. [8]

In national administrative data samples, the prevalence of degenerative spinal disease diagnoses fluctuates around 27% and increases sharply with age, more often in obese individuals and in the presence of imaging (the "detection" effect). In population-based studies, the prevalence of cervical spondylosis in some cohorts reached 13.76%, with a peak at ages 45–60 years. These estimates vary based on methodology and access to care. [9]

Table 2. Key figures on prevalence

Indicator	Meaning
Low back pain, 2020 (global)	619,000,000 cases
Forecast for 2050	843,000,000 cases
MRI of disc degeneration in asymptomatic patients	from 37% (20 years) to 96% (80 years)
Cervical spondylosis (selected cohorts)	≈13.76% (age 45-60 years) [10]

Reasons

The basis of "osteochondrosis" is the multifactorial degeneration of the intervertebral discs and facet joints, accelerated by mechanical overload, genetic, and metabolic factors. With age, the nucleus pulposus loses water and proteoglycans, the elasticity of the annulus fibrosus decreases, cracks and a decrease in disc height occur. These processes are often part of normal aging, but when combined with other factors, they produce clinical symptoms. [11]

Repetitive strain, awkward static postures, vibration, and trauma all play a role. Smoking, obesity, low physical activity, and sleep deprivation are associated with a higher frequency of exacerbations. In the cervical spine, prolonged use of gadgets and forced head posture are also significant. [12]

Genetic predisposition influences the rate and severity of changes in discs and ligaments, while comorbidities (diabetes, osteoporosis) influence tissue regenerative potential and pain phenotype. Finally, psychosocial factors (stress, depression) increase pain perception and hinder active recovery—this is taken into account in modern biopsychosocial models. [13]

Risk factors

Non-modifiable factors include age, heredity, and female gender (for some pain phenotypes). Among modifiable factors, the most significant are obesity, smoking, physical inactivity, sedentary work, and heavy physical labor involving lifting. Occupational vibrations (for example, in drivers) accelerate the development of lumbar changes. [14]

Psychosocial determinants such as catastrophizing, fear of movement, depression, and low job satisfaction contribute to a high risk of long-term pain. Current guidelines recommend early risk stratification and the use of cognitive-behavioral approaches in high-risk patients. [15]

Separately, "red flags" are identified that are not risk factors for osteochondrosis but indicate other dangerous causes of pain (tumor, infection, fracture, cauda equina syndrome). Their identification is part of the initial examination. [16]

Pathogenesis

Disc degeneration is accompanied by loss of water and proteoglycans, decreased hydrostatic pressure, and decreased ability of the disc to distribute loads. Fissures in the annulus fibrosus, protrusions, and herniations occur, and reactive spondylosis and osteophytes develop. At the facet joint level, capsular inflammation and arthrosis occur, resulting in localized pain and muscle spasm. [17]

Immune and neurogenic mechanisms support chronic pain: nerve endings grow into damaged areas of the disc, sensitizing peripheral and central pain structures. Involvement of the nerve roots (radiculopathy) results in radicular pain syndrome with irradiation and neurological deficit. [18]

Not all morphological changes cause symptoms: pain phenotype, psychosocial factors, and movement patterns play a significant role. Therefore, treatment strategies combine physical activity, education, and, if necessary, pharmacotherapy and manual techniques as a "package," rather than as isolated interventions. [19]

Symptoms

The leading symptom is back or neck pain: acute, subacute, or chronic; localized or radiating to the arm/leg. Limited movement and morning stiffness are possible, increasing with static postures and decreasing with walking. With radicular pain, shooting pain, paresthesia, and weakness in the innervation zone appear. [20]

Night pain, fever, progressive weakness, and urinary and bowel problems are not typical of osteochondrosis and require the exclusion of dangerous causes. In some people, symptoms recur in waves, while in others they become chronic with episodes of exacerbation. [21]

A gradation based on impact on life is more important than raw pain figures: sleep, work capacity, daily activities, and psycho-emotional state are assessed. This helps prioritize treatment and set realistic goals. [22]

Classification, forms and stages

Clinically, the following are distinguished: 1) local dorsalgia without neurological deficit; 2) radiculopathy (radicular syndrome); 3) spinal stenosis with neurogenic intermittent claudication (usually lumbar); 4) cervical myelopathy (rare, but important to recognize). In ICD-11, the "structural" part is coded in the FA80-FA8Z block, and the pain syndrome - in MG30. [23]

Pain progression is classified as acute (up to 6 weeks), subacute (6-12 weeks), and chronic (more than 12 weeks). This gradation helps determine the intensity of interventions and management tactics. [24]

Table 3. Clinical forms (summary)

Form	Key Features	What is important not to miss
Mechanical dorsalgia	Local pain sensitive to stress	Red flags
Radiculopathy	Pain along the dermatome, paresthesia, weakness	Progressive deficiency
Stenosis (lumbar)	Worse when walking and straightening, better when bending	Gait disturbances, falls
Cervical myelopathy	Clumsiness of hands, gait disturbance, hyperreflexia	Urgent consultation with a neurosurgeon [25]

Complications and consequences

Safety first: progressive neurological deficits (increasing weakness) and cauda equina syndrome (pelvic dysfunction, saddle anesthesia) are reasons for urgent hospitalization. In cervical myelopathy, the "window of opportunity" for neurosurgery is limited: early referral improves outcomes. [26]

In chronic cases, physical activity and quality of life decrease, and the risk of anxiety/depression and temporary disability increases. Prolonged immobility worsens the prognosis, exacerbating the pain phenotype and sarcopenia. Therefore, modern protocols emphasize early activation and education. [27]

When to see a doctor

Immediately - if any of the following "red flag" symptoms are present: fever, trauma in the elderly, progressive weakness, urinary/defecatory problems, history of cancer, unbearable pain at night. These signs increase the likelihood of a specific pathology. [28]

In the coming days - for severe pain that interferes with self-care, numbness/paresthesia, or if initial measures are ineffective within 1-2 weeks. Planned - for recurring episodes affecting work and sleep, to determine an exercise program, pain relief, and behavioral strategies. [29]

Diagnostics

Step 1. History and examination. The doctor determines the duration and nature of the pain, aggravating/alleviating factors, the presence of radiation, and any "red flags." A neurological examination is performed: strength, sensation, reflexes, straight leg raise test (for the lower back), spur test (for the neck), and gait assessment. [30]

Step 2. Decide on imaging. In the absence of red flags and with a typical presentation, imaging is not necessary at the outset. If pain persists or there is a neurological deficit, an MRI of the relevant area is performed; X-rays are useful if instability, deformity, or fracture is suspected. CT and myelography are used for specific indications (e.g., surgical planning, stenosis). Blood tests are performed as needed (inflammation, infection, tumor). [31]

Step 3. Interpretation. Remember that a "finding" on the image is not always associated with pain: with age, signs of degeneration occur in most people even without symptoms. The decision on tactics is made in the context of the clinical picture and the patient's goals. [32]

Step 4. Risk stratification. Patients with a high risk of chronicity (based on questionnaires and psychosocial factors) are referred to more intensive combination programs (exercise + psychological approach, sometimes manual techniques as part of the package). [33]

Table 4. When visualization is needed (brief summary of recommendations)

Situation	Tactics
No red flags, acute/subacute pain	Without visualization, active strategies
Suspicion of a specific pathology	MRI/CT as indicated
Neurological deficit, stenosis, myelopathy	Urgent/planned MRI
Preparing for surgery	Targeted imaging and neurophysiology [34]

Differential diagnosis

Not all back pain is osteochondrosis. Dangerous "mimickers" include tumors, infections (spondylodiscitis), compression fractures associated with osteoporosis, and inflammatory spondyloarthritis. In young people with nighttime pain and stiffness, consider spondyloarthritis; in older people with sudden pain following a "microtrauma," consider a fracture. [35]

When a leg hurts, it's important to distinguish radiculopathy from peroneal nerve neuropathy or vascular claudication; when arm pain occurs, it's important to distinguish cervicobrachialgia from shoulder syndromes. Gait disturbances are differentiated between stenosis (worse when walking, better when bending) and vascular insufficiency (depending on muscle load). Proper questions and tests save time and prevent unnecessary "MRI scrambles." [36]

Treatment

A modern approach begins with education and activation. The patient receives an explanation of the nature of pain, exacerbation factors, and safe movement strategies. Early return to normal activity is an important predictor of a good outcome. Exercises are individually tailored: aerobic exercises, exercises for core mobility and stabilization, and neurodynamic techniques for radicular syndrome. Effectiveness is higher when exercises are part of a structured program with feedback. [37]

Pharmacotherapy is dosed in minimally sufficient courses. For acute pain, nonsteroidal anti-inflammatory drugs are used in short courses, taking into account the risks to the gastrointestinal tract and heart. Paracetamol alone is ineffective. For chronic pain, exercise is useful as a first-line treatment; antidepressants from certain groups and manual therapy can be considered as part of a treatment package. Opioids are not recommended for nonspecific pain due to their poor efficacy and risks. [38]

Manual methods (mobilization, manipulation, soft tissue techniques) are acceptable as part of a "combination package" along with exercises and, if necessary, a psychological approach. Traction, ultrasound, TENS, interference therapy, and "insoles/belts" are not recommended by current guidelines due to a lack of evidence of benefit. This allows for a focus on truly effective strategies and the conservation of resources. [39]

Cognitive-behavioral approaches help reduce fear of movement, catastrophizing, and improve adherence to active recovery. Homework assignments are essential: gradual exposure to movement, an activity and pain trigger diary, and self-regulation skills. This format is most beneficial for patients at high risk for chronic pain. [40]

For radicular syndrome, a step-by-step approach is used: analgesics and neurodynamic exercises; if pain and functional limitations persist, image-guided injection methods (epidural steroids) are considered; their effect is moderate and short-term, and the decision is made on an individual basis. For stenosis with neurogenic claudication, bending while walking, bicycle ergometers, and endurance and flexibility programs are helpful; surgery is considered for severe limitations. [41]

Surgical treatment is indicated for a limited number of patients: progressive neurological deficit, cauda equina syndrome, persistent pain with confirmed compression and the ineffectiveness of conservative therapy. For disc herniations - microdiscectomy; for stenosis - decompression with/without stabilization; for cervical myelopathy - anterior/posterior decompressive surgeries. The choice of method depends on the level, anatomy, concomitant conditions and the patient's goals. [42]

Technologies are advancing: digital self-management programs with remote monitoring, smart activity trackers, and telerehabilitation. They increase adherence, provide the doctor with objective data between visits, and allow for faster plan adjustments. At the same time, digital technologies are a complement to core treatment, not a replacement for human interaction and high-quality physical therapy. [43]

Controversial/popular, but poorly evidenced methods (numerous physical therapy procedures, routine injections "at the point of pain," prolonged immobilization) are giving way to active strategies. A review of clinical guidelines from various countries reveals a consensus: movement, education, short courses of nonsteroidal anti-inflammatory drugs when necessary, a psychological component, and the selective use of manual therapy and injections. [44]

Finally, a "sick days" plan: during an exacerbation, maintain available activities, use short courses of pain medication, protect sleep, maintain hydration, and if neurological symptoms worsen, seek help immediately. Writing down an individual plan (what to do first, second, and third) reduces anxiety and speeds the return to normal life. [45]

Table 5. What really works (summary of recommendations)

Approach	Status in recommendations
Training and early activation	Recommended
Exercise programs (aerobic, stabilization, neurodynamics)	Recommended
Manual therapy as part of a package (with exercises ± psychotherapy)	Consider
Nonsteroidal anti-inflammatory drugs (briefly, according to indications)	Consider
Traction, TENS, ultrasound, belts/insoles	Not recommended
Visualization without red flags	Not recommended
Surgery for deficit/persistent pain syndrome with compression	According to the indications [46]

Prevention

Daily activity and regular exercise reduce the risk of flare-ups: combine aerobic exercise, strength training for the back and core muscles, and mobility exercises. Work at a desk with lumbar support, keep the monitor at eye level, and take breaks every 30-60 minutes. [47]

Weight management and smoking cessation reduce inflammatory load and mechanical stress on the spine. Sleep is an important "pill": lack of sleep increases pain and reduces exercise tolerance. [48]

Mental hygiene is part of prevention: stress management, realistic expectations, and self-help skills. The sooner a person understands that "it's safe to move," the lower the risk of chronicity. [49]

Forecast

Most episodes of acute back pain improve within a few weeks with proactive management. The risk of chronicity is related not only to the degree of wear and tear but also to psychosocial factors, physical fitness, and sleep quality. Personalized goals and regular feedback from the team improve outcomes. [50]

Even with significant MRI findings, the prognosis can be favorable with the right combination of education, exercise, and targeted drug therapy. Timely surgery, when clearly indicated, restores function and reduces pain. [51]

FAQ

1. Is "osteochondrosis" a diagnosis or a catch-all term?
In ICD-10, it's code M42, but in modern practice, it's more accurate to say "degenerative spinal disease," with further clarification: disc degeneration, spondylosis, stenosis, etc. ICD-11 uses detailed codes FA80-FA8Z and, if desired, pain syndrome codes MG30. [52]

2. Why didn't the doctor order an MRI right away?
Because in the absence of "red flags," early imaging doesn't improve outcomes and may reveal age-related changes unrelated to your pain. An MRI is necessary if the results will impact your treatment plan. [53]

3. My MRI shows a "hernia." Does this always require surgery?
No. Most hernias are treated conservatively: exercises, pain management, education, and sometimes injections. Surgery is needed for progressive deficits, cauda equina syndrome, or persistent pain with documented compression. [54]

4. Which exercises are the most "correct"?
Those that you do regularly and that are tailored to your goals: aerobics, core stabilization, flexibility, and neurodynamics for radicular syndrome. Effectiveness increases with a training program. [55]

5. Do belts, traction, and ultrasound help?
Current guidelines advise against them: the evidence base is weak. Active strategies, education, and short courses of medication as indicated are better. [56]

6. Are chondroprotectors necessary?
There is no convincing evidence base for the treatment of back pain and osteochondrosis; these drugs are not standard in international recommendations. Focus on active and proven methods. [57]

7. What to do during an exacerbation?
Maintain moderate activity, use short courses of pain medication, protect your sleep, and if you experience irradiation or numbness, consult a doctor. If you experience any red flags, seek immediate hospitalization. [58]

8. Can a hernia be "straightened" with exercise?
Exercises reduce pain and improve function, but they do not necessarily make morphological changes on MRI "disappear." The goal is to return to normal life safely and effectively. [59]

9. Why does pain return?
Because it's influenced by exercise, stress, sleep, muscle condition, and habits. A self-care plan, regular exercise, and lifestyle adjustments reduce the frequency of relapses. [60]

10. What is the prognosis for osteochondrosis?
In most cases, it's good with proactive management. The key is to stay active, understand your problem, and have a plan for the "bad days." [61]
