Chronic low back pain due to degenerative disc disease is sometimes treated with fusion. We compared the outcome of three different fusion techniques in the Swedish Spine Register: noninstrumented posterolateral fusion (PLF), instrumented posterolateral fusion (IPLF), and interbody fusion (IBF). A total of 2874 patients who were operated on at one or two lumbar levels were followed for a mean of 9.2 years (3.6 to 19.1) for any additional lumbar spine surgery. Patient-reported outcome data were available preoperatively (n = 2874) and at one year (n = 2274), two years (n = 1958), and a mean of 6.9 years (n = 1518) postoperatively and consisted of global assessment and visual analogue scales of leg and back pain, Oswestry Disability Index, EuroQol five-dimensional index, 36-Item Short-Form Health Survey, and satisfaction with treatment. Statistical analyses were performed with competing-risks proportional hazards regression or analysis of covariance, adjusted for baseline variables.Aims
Patients and Methods
The purpose of this study was to investigate the risk of additional surgery in the lumbar spine and to describe long-term changes in patient-reported outcomes after surgery for lumbar disc herniation in adolescents and young adults. We conducted a retrospective study design on prospectively collected data from a national quality register. The 4537 patients were divided into two groups: adolescents (≤ 18 years old, n = 151) and young adults (19 to 39 years old, n = 4386). The risk of additional lumbar spine surgery was surveyed for a mean of 11.4 years (6.0 to 19.3) in all 4537 patients. Long-term patient-reported outcomes were available at a mean of 7.2 years (5.0 to 10.0) in up to 2716 patients and included satisfaction, global assessment for leg and back pain, Oswestry Disability Index, visual analogue scale for leg and back pain, EuroQol five-dimension questionnaire (EQ-5D), and 36-Item Short-Form Health Survey (SF-36) Mental Component Summary and Physical Component Summary scores. Statistical analyses were performed with Cox proportional hazard regression, chi-squared test, McNemar’s test, Welch–Satterthwaite Aims
