Evaluation of the Effectiveness and Safety of Mesotherapy in the Treatment of Chronic Low Back Pain Syndrome

The aim of this study is to evaluate the effectiveness of collagen mesotherapy in the treatment of chronic low back pain (CLBP) in the lumbosacral spine. Mesotherapy is expected to reduce pain in the lumbosacral region, decrease soft tissue tension (including muscles, fascia, and ligaments), improve spinal mobility, and support subsequent physiotherapy. A total of five treatment sessions will be performed at weekly intervals. During each session, approximately 20 intradermal microinjections will be administered into the paraspinal soft tissues of the lumbosacral region. Participants will receive injections of either type I tropocollagen, 1% lignocaine (lidocaine), or a combination of both, with a volume of 0.1 mL per injection.

Inclusion Criteria: Age between 18 and 65 years Chronic localized pain in the lumbosacral spine without radicular symptoms or radiation to the lower limbs Recent spinal imaging (X-ray, computed tomography (CT), or magnetic resonance imaging (MRI)) performed within the last 6 months confirming the diagnosis Exclusion Criteria: Known allergy to collagen or lignocaine Active malignancy Autoimmune diseases Skin lesions in the lumbosacral region Active infection Lack of informed consent
