Assessment of long term results of Chemonucleolysis vs. surgery for soft disc herniation From 1982 to 1985, 100 patients with symptomatic disc herniation were randomly allocated to receive either Chemonucleolysis(48) or surgery(52) after a three months trial of conservative treatment. Ten of the chemonucleolysis had surgery. At 10–13 year follow up, Sixty one of the original 100 patients responded, (32 chemonucleolysis; 29 surgery). At 25–27 year Forty four patients responded (24 chemonucleolysis; 20 surgery). Clinical outcome at one year was according to a self-assessment questionnaire: Completely, better improved, the same, or worse, and at the later follow up periods, according to the Macnab criteria. The results of two groups of patients were compared using Chi square and T test for independent samples. The disc height of the affected disc was measured from the lateral lumbar spine radiograph taken pre-operatively, and at the later two time points, and compared to a normal adjacent disc expressed as a percentage.Purpose of the Study
Material and Methods
To compare the efficacy and safety of balloon kyphoplasty (BKP) to non-surgical management (NSM) over 24 months in patients with acute painful fractures by clinical outcomes and vertebral body kyphosis correction and surgical parameters. Three hundred Adult patients with one to three VCF's were randomised within 3 months of the acute fracture; 149 to Balloon Kyphoplasty and 151 to Non-surgical management. Subjective QOL assessments and objective functional (Timed up and go [TUG]) and vertebral body kyphotic angulation (KA), were assessed over 24 months; we also report surgical parameters and adverse events temporally related to surgery (within 30-days).Purpose
