      • Changes in the Spinopelvic Parameters of Elite Weight Lifters

        Yang, Jae Hyuk,Barani, Rathinavelu,Bhandarkar, Amit Wasudeo,Suh, Seung Woo,Hong, Jae Young,Modi, Hitesh N.,Yang, Jae Hyuk by Lippincott Williams Wilkins 2014 Clinical journal of sport medicine Vol.24 No.4

        OBJECTIVE:: To describe the changes in the spinopelvic parameters in weight lifters and evaluate the factors leading to spinal anatomical changes (eg, spondylolysis and listhesis). DESIGN:: Case–control study. SETTING:: Tertiary, institutional. PARTICIPANTS:: The study group participants were practicing weight lifters in the athletes’ village of the 2012 London Olympics. A total of 21 elite weight lifters were enrolled. Their data were compared with those of 45 healthy volunteers in the control group. INTERVENTIONS:: Comparative radiological evaluations were performed among the 21 elite weight lifters. Spinopelvic parameters (radiographic analysis), including total (TLL), upper (ULL), and lower (LLL) lumbar lordoses, sacral slope, pelvic tilt (PT) and incidence, lumbar index, and disc angles, were assessed. MAIN OUTCOME MEASURES:: The proportional ratio of ULL and LLL to TLL (ULL/TLL and LLL/TLL) was measured to describe the proportion effect. These values were compared with those of the control group. Weight lifters with and those without anatomical changes were subdivided into a deformed and nondeformed group, respectively, and further analyzed for differences. The correlation between these spinal parameters and the amount and duration of weight lifting training was also analyzed. RESULTS:: Anatomical changes in the lumbar spine were seen in 6 weight lifters (28.6%, P = 0.01). The mean TLL, ULL, and LLL values (59.8, 22.6, and 37.2 degrees, respectively) were increased, whereas PT (10.3 degrees) was decreased in the athletes compared with the volunteers (P = 0.001, 0.005, 0.07, and 0.018, respectively). The ULL/TLL was higher in the deformed group than in the nondeformed group (P = 0.036). The duration and amount of weight lifting training were not correlated with the spinopelvic parameters measured in this study. CONCLUSIONS:: The elite weight lifters had increased lumbar lordosis and decreased PT compared with the healthy volunteers. The ULL/TLL ratio may be used as a predictive marker for lumbar deformation.

        Lumbar Spinal Steroid Injections and Infection Risk after Spinal Surgery: A Systematic Review and Meta-Analysis

        Patel Harshadkumar A.,Cheppalli Naga Suresh,Bhandarkar Amit Wasudeo,Patel Vidhi,Singla Anuj 대한척추외과학회 2022 Asian Spine Journal Vol.16 No.6

        Lumbar spinal steroid injections (LSSI) are universally used as preferred diagnostic or therapeutic treatment options before major spinal surgeries. Some recent studies have reported higher risks of surgical-site infection (SSI) for spinal surgeries performed after injections, while others have overlooked such associations. The purpose of this study is to systematically review the literature and perform a meta-analysis to evaluate the associations between preoperative LSSI and postoperative infection following subsequent lumbar decompression and fusion procedures. Three databases, namely PubMed, Scopus, and Cochrane Library, were searched for relevant studies that reported the association of spinal surgery SSI with spinal injections. After the comprehensive sequential screening of the titles, abstracts, and full articles, nine studies were included in a systematic review, and eight studies were included in the meta-analysis. Studies were critically appraised for bias using the validated MINOR (methodological index for non-randomized studies) score. The odds ratio (OR) and 95% confidence interval (CI) were calculated. Subgroup analysis was performed according to the time between LSSI and surgery and the type of lumbar spine surgery. Meta-analysis showed that preoperative LSSI within 30 days of lumbar spine surgery was associated with significantly higher postoperative infection compared with the control group (OR,1.79; 95% CI, 1.08–2.96). Based on subgroup analysis, lumbar spine fusion surgery within 30 days of preoperative LSSI was associated with significantly high-infection rates (OR, 2.67; 95% CI, 2.12–3.35), while no association was found between preoperative LSSI and postoperative infection for lumbar spine decompression surgeries. In summary, given the absence of high-level studies in the literature, careful clinical interpretation of the results should be performed. The overall risk of SSI was slightly higher if the spinal surgery was performed within 30 days after LSSIs. The risk was higher for lumbar fusion cases but not for decompression-only procedures.
