The aim of this study was to determine whether
obesity affects pain, surgical and functional outcomes following lumbar
spinal fusion for low back pain (LBP). A systematic literature review and meta-analysis was made of
those studies that compared the outcome of lumbar spinal fusion
for LBP in obese and non-obese patients. A total of 17 studies were
included in the meta-analysis. There was no difference in the pain
and functional outcomes. Lumbar spinal fusion in the obese patient resulted
in a statistically significantly greater intra-operative blood loss
(weighted mean difference: 54.04 ml; 95% confidence interval (CI)
15.08 to 93.00; n = 112; p = 0.007) more complications (odds ratio:
1.91; 95% CI 1.68 to 2.18; n = 43858; p <
0.001) and longer duration
of surgery (25.75 mins; 95% CI 15.61 to 35.90; n = 258; p <
0.001). Obese
patients have greater intra-operative blood loss, more complications
and longer duration of surgery but pain and functional outcome are
similar to non-obese patients. Based on these results, obesity is
not a contraindication to lumbar spinal fusion. Cite this article:
To Determine Whether Maximal Rib Prominence Measured On Lateral Radiographs Can Be Used As A Surrogate To Rib Rotation Determined By Surface Tomography (Quantecscanning) In Assessment Of Spinal Rotation. Patients With Adolescent Idiopathic Scoliosis Underwent Plain Lateral Radiographs And Quantec Scans. Maximal Rib Prominence On The Lateral Radiograph Was Defined Pre- And Post-Operatively By Distance From Most Posterior Aspect Of The Rib To The Facet Joint And Instrumented Rod, Respectively. Rib Rotation Was Measured By Surface Tomography Quantec Scan Using The Suzuki Method. This Was Then Repeated At A Later Time And By An Additional Investigator To Assess Intra- Observer And Inter-Observer Variability. The Correlation Between Maximal Rib Prominence And The Suzuki Ratio Was Determined.Aim:
