[Minimally invasive surgery in treatment of lumbar intervertebral disc herniation]

Surgical treatment of lumbar intervertebral disc herniation is one of the most common neurosurgical procedures. Besides conventional surgical techniques, in the last more than 30 years, different methods with minimal damage to neuromuscular spine structures are being developed and introduced, all having the purpose of reducing postoperative back pain. The advantages of the minimally invasive spine surgery include: possibility of performing procedures under local anaesthesia, reduced hospital stay, limited blood loss with consecutively reduced fibrous tissue development. Patients are capable of return to work and everyday activities early after surgery. From the economical point of view, this kind of treatment is considered to be a cost-effective intervention. Three methods that are being used for treatment of lumbar intervertebral disc herniation are: percutaneous laser disc decompression (PLDD), microdiscectomy using tubular retractor system and selective endoscopic discectomy (SED). Conducted prospective studies have shown that minimally invasive methods are adequate alternative to classic surgical procedures.
