Search for: [Abstract = "The aim of the presented study was to evaluate the effectiveness of discectomy with instrumented posterior lumbar interbody fusion \(PLIF\). Following questions were posed\:1. What are the long term biomechanical effects of instrumented PLIF in patients with lumbar discopathy\?2. What is the long term quality of life of patients with lumbar discopathy treated with instrumented PLIF\?3. What are the results of nonoperative treatment of lumbar discopathy and what do they depend on\?4. Is there a correlation between radiologic degenerative changes and the severity of pain\?5. Which of the presented methods of treatment leads to a better long term outcome\?The study was conducted basing on the material from University Hospital in Zakopane and comprised 140 patients – 68 men \(that is 49%\) and 72 women \(51%\). Age distribution was from 23 to 79 years \(mean 52\+\/\-13\). There were no statistical differences between age, sex and type of treatment. Patients were divided in two groups\: I – treated surgically, II – treated nonoperatively.Methodology included clinical, radiologic and subjective evaluation. Above that patients’ quality of life was assessed.Radiologic evaluation included analysis of lumbar spine ap and lateral films, preoperatively, immediately postoperatively and at final follow\-up.
