[The chondroprotector mucosat in an integrated approach to the treatment of nonspecific back pain]

A nonspecific back pain is in the vast majority of all possible cases of dorsopathies. The sources of back pain may be myogenic dysfunction, intervertebral disc pathology or osteoarthritis of the archicular (facet) joints of the spine, including myofascial pain syndrome. A differentiated approach to the treatment of spondylarthrosis is still an unsolved problem. The article discusses important issues of integration of non-drug treatment methods and drug therapy of nonspecific back pain in patients with facet syndrome. Special attention is paid to SYSADOA group chemicals, in particular chondroitin sulfate (mucosat). These drugs have proven analgesic and anti-inflammatory effects and also are able to improve the structure of the cartilaginous tissue, slowing the progression of the disease.

Microcalcification of lumbar spine intervertebral discs and facet joints is associated with cartilage degeneration, but differs in prevalence and its relation to age

Cartilage calcification (CC) is associated with degeneration in non-vertebral joints, but little is known about CC and lumbar vertebral joints. The goal of this study was to analyze the prevalence of CC in lumbar facet joints (FJ) and intervertebral discs (IVD) and its relation to cartilage degeneration and age in a non-selected cohort of the general population. The segment L4/5 of 85 consecutive donors (mean age 61.9 years) was analyzed by high-resolution imaging digital-contact radiography (DCR). Quantification was achieved by measuring CC in % of total cartilage area. Histological degeneration of FJs and IVDs was determined by OARSI and Boos scores. Prevalence of CC was 36.5% for FJ (95%CI (0.26, 0.48)) and 100% for IVD (95%CI (0.96, 1.00)). The amount of IVD CC (3.36% SD ± 7.14) was 16.3 times higher (p < 0.001) than that of the FJ (0.23% SD ± 0.53) and independent of each other (p = 0.07). The amount of FJ CC correlated significantly with FJ and IVD degeneration (FJ r = 0.44, p = 0.01, IVD r = 0.49, p = 0.006) while the amount of IVD CC correlated only with IVD degeneration (r = 0.54, p < 0.001). Age correlated with IVD CC (r_s  = 0.35, p < 0.001), but not FJ CC (r_s  = 0.04, p = 0.85). We conclude that IVD fibrocartilage is particularly prone to calcification. A causal relationship between lumbar CC and degeneration is possible, but the clear differences in IVD fibrocartilage CC and FJ synovial joint CC in regard to prevalence and in relation to age point to a differential role of CC in single compartments of the respective motion segment in lumbar spine degeneration. © 2017 Orthopaedic Research Society.
