CLINICAL GUIDELINES 
Examination of a patient with chronic low back pain (LBP) is aimed at eliminating its specific cause and assessing the social and psychological factors of chronic pain. The diagnosis of chronic nonspecific (musculoskeletal) LBP is based on the exclusion of a specific cause of pain, discogenic radiculopathy, and lumbar stenosis. It is advisable to identify possible pain sources: pathology of intervertebral disc pathology, facet joints, and sacroiliac joint and myofascial syndrome.
An integrated multidisciplinary approach (a high level of evidence), including therapeutic exercises, physical activity optimization, psychological treatments (cognitive behavioral therapy), an educational program (back pain school for patients), and manual therapy, is effective in treating chronic musculoskeletal LBP. For pain relief, one may use nonsteroidal anti-inflammatory drugs in minimally effective doses and in a short cycle, muscle relaxants, and a capsaicin patch, and, if there is depressive disorder, antidepressants (a medium level of evidence). Radiofrequency denervation or therapeutic blockages with anesthetics and glucocorticoids (damage to the facet joints, sacroiliac joint), back massage, and acupuncture (a low level of evidence) may be used in some patients.
Therapeutic exercises and an educational program (the prevention of excessive loads and prolonged static and uncomfortable postures and the use of correct methods for lifting weights, etc.) are recommended for preventive purposes.

Objective: to compare the efficiency of medical and surgical treatments for discogenic low back radiculopathy.
Patients and methods. 32 patients (including 13 men; mean age, 39.1±11.8 years) received inpatient medical treatment with epidural glucocorticoids; 32 patients (including 19 men; mean age. 42.3±12.1 years) had surgical treatment (removal of a herniated disk). A questionnaire [numerical pain rating scale (NPRS), Oswestry disability index, and quality of life questionnaire (QOL), SF-12] survey was carried out on admission to the clinic, after 7–14 days during treatment (pain intensity and functional status), and after 3, 6, and 12 months.
Results and discussion. There were no clinical differences between the patient groups at baseline. Both groups showed a significant decrease in pain intensity and reduced disability after 7–14 days of treatment, with a persistent positive effect over 12 months (p < 0.01). During a year, both groups exhibited better quality of life (p < 0.01). In the surgical treatment group, leg pain intensity was noted to become lower in the early stages (NPRS scores were 0.97 vs 2.41 after 7–14 days and 0.84 vs 1.56 scores after 3 months; p < 0.05); however, this advantage did not persist in the long-term. No significant differences were found between the groups in back pain intensity, disability, and QOL indicators throughout the follow-up period.
Conclusion. There were no significant clinical differences between patients with discogenic low back radiculopathy who are referred to hospital for surgical or medical treatment. Surgery makes it possible to reduce more rapidly the intensity of leg pain; however, no benefits of surgical treatment in terms of back pain intensity, disability, and QOL are noted. It is advisable to inform patients about the favorable course of the disease and the possibility of natural regression of disc herniation.
Objective: to analyze the typical medical practice management of patients with carpal tunnel syndrome (CTS), to evaluate the efficiency of surgical treatment, and to identify factors influencing the successful outcomes of surgical treatment.
Patients and methods. The investigation enrolled 85 patients (14 men and 71 women; mean age, 62±10.8 years). Previous diagnosis and treatment of patients were assessed in other healthcare facilities. All patients underwent median nerve decompression. The efficiency of surgical treatment was assessed according to the Boston Carpal Tunnel Questionnaire (BCTQ) and a visual analogue scale for pain before and 1, 3, 6, and 12 months after surgery.
Results and discussion. Informative diagnostic tests are rarely performed in patients with CTS, but cervical spine neurovisualization is often unreasonably prescribed. Erroneous diagnoses (predominantly those of cervical spine osteochondrosis (46%), and diabetic neuropathy (6%)) are made frequently (60%) in patients with CTS; the latter receive ineffective treatment for a long time. Surgical treatment in reducing pain and improving hand functionality is noted to be highly effective. The mean BCTQ score decreased from 2.81±0.68 to 1.62±0.55 and 1.24±0.41 at 1 and 12 months, respectively (p<0.05), the mean functional state score dropped from 2.92±0.78 to 2.4±0.72 and 1.46±0.57, respectively (p<0.05). Permanent numbness, subjective weakness, thenar muscle atrophy, Stage III CTS, and diabetes mellitus are predictors for less pronounced improvement in BCTQ scores after surgery (p<0.05).
Conclusion. Physicians are noted to be unaware of the manifestations of CTS and effective methods for its diagnosis and treatment. Decompression surgery is shown to be a highly effective procedure in patients with CTS following 1 and 12 months.
