Objective: Revision surgery is often necessary for adult spinal deformity (ASD) patients. Satisfaction with management is an important component of health-related quality of life. The authors hypothesized that patients who underwent multiple revision surgeries following ASD correction would exhibit lower self-reported satisfaction scores., Methods: This was a retrospective cohort study of 668 patients who underwent ASD surgery and were eligible for a minimum 2-year follow-up. Visits were stratified by occurrence prior to the index surgery (period 0), after the index surgery only (period 1), after the first revision only (period 2), and after the second revision only (period 3). Patients were further stratified by prior spine surgery before their index surgery. Scoliosis Research Society-22 (SRS-22r) health-related quality-of-life satisfaction subscore and total satisfaction scores were evaluated at all periods using multiple linear regression and adjustment for age, sex, and Charlson Comorbidity Index., Results: In total, 46.6% of the study patients had undergone prior spine surgery before their index surgery. The overall revision rate was 21.3%. Among patients with no spine surgery prior to the index surgery, SRS-22r satisfaction scores increased from period 0 to 1 (from 2.8 to 4.3, p < 0.0001), decreased after one revision from period 1 to 2 (4.3 to 3.9, p = 0.0004), and decreased further after a second revision from period 2 to 3 (3.9 to 3.3, p = 0.0437). Among patients with spine surgery prior to the index procedure, SRS-22r satisfaction increased from period 0 to 1 (2.8 to 4.2, p < 0.0001) and decreased from period 1 to 2 (4.2 to 3.8, p = 0.0011). No differences in follow-up time from last surgery were observed (all p > 0.3). Among patients with multiple revisions, 40% experienced rod fracture, 40% proximal junctional kyphosis, and 33% pseudarthrosis., Conclusions: Among patients undergoing ASD surgery, revision surgery is associated with decreased satisfaction, and multiple revisions are associated with additive detriment to satisfaction among patients initially undergoing primary surgery. These findings have direct implications for preoperative patient counseling and establishment of postoperative expectations.

Background: Spinal cord stimulation (SCS) has become a successful therapeutic option for combating chronic pain and can be implanted via percutaneous or open (laminotomy/laminectomy) techniques. This study aimed to systematically review the complications that occur after SCS placement via percutaneous and open (laminotomy/laminectomy) in failed back surgery syndrome (FBSS), complex regional pain syndrome (CRPS), and chronic back (lumbosacral)/leg pain., Methods: The PubMed and Embase databases were searched from inception to June 2020; prospective studies using SCS in patients with FBSS, CRPS, and chronic low back pain that reported both complications and the implantation method used were included. Effects and results from each study were combined using a random-effects model and were structured for subgroup analysis between open implantation and percutaneous implantation. Meta-regression was performed by calculating a mean difference and weighted by inverse variance and 95% confidence intervals (CIs)., Results: Thirty-two articles were included in this systematic review and meta-analysis. Using several different patient- and event-based metrics, our meta-analysis revealed an overall average complication rate of 21.1% (95% CI, 14.9-27.2). Equipment, technical, and medical complications occurred at rates of 12.1%, 1.1%, and 6.3%, respectively. Lead migration and infection rates were 5.6% and 3.8%, respectively. When comparing the 2 implant techniques, medical-related surgical reinterventions and explants due to infection were more common in open compared with percutaneous SCS procedures., Conclusions: Equipment-related complications accounted for the majority of SCS complications. Percutaneous SCS resulted in less reintervention and fewer explants caused by medical-related complications and infection, respectively. These conclusions may provide a general understanding of the SCS complications profile for physicians who care for SCS patients., (Copyright © 2021 Elsevier Inc. All rights reserved.)

Femoroacetabular impingement (FAI) is the most common cause of hip pain in both professional and recreational athletes. It is caused by abnormal bone development on both the acetabulum and proximal femur as a result of genetic factors and in reaction to high-volume athletics participation. Athletes typically become symptomatic after reaching skeletal maturity and commonly describe deep groin pain that worsens with activities such as squatting, cutting, or pivoting motions. For this reason, sports such as hockey, football, and soccer can be particularly irritating to an athlete with FAI. Moreover, the athlete with FAI often presents with contaminant hip and pelvis pathologies such as athletic pubalgia and iliopsoas tendinopathy that must also be addressed. While this pain often limits performance or participation in sports, perhaps the most significant ramification of FAI is the role it plays in driving early onset osteoarthritis. Fortunately, FAI can be reliably diagnosed through careful history taking, appropriate provocative physical exam maneuvers, and familiarity with hallmark radiographic features. The aims of this review are to provide clinicians with information regarding the pathogenesis of FAI, to thoroughly describe the classic history and physical exam elements, and to introduce various management strategies for athletes suffering from FAI.

Objective: Sexual function is an important factor contributing to quality of life. Adult spinal deformity (ASD) patients may have sexual limitations due to lumbar spinal stiffness that may be affected by long-segment fusion., Methods: This study utilized a multicenter, prospectively defined, consecutive cohort of ASD patients. The primary outcome in this study was the Lumbar Stiffness Disability Index (LSDI) question 10: "Choose the statement that best describes the effect of low back stiffness on your ability to engage in sexual intercourse"., Results: In total, 368 patients were included in this study, including 76 men and 292 women, of which 80.7% (n = 293) underwent 9 or more level fusion and 74.4% (n = 270) had pelvic fixation. Baseline LSDI sexual function scores averaged 1.7 (SD 1.3), which improved to 1.3 (SD 1.2) at 2-year follow-up (P = 0.0008). After adjusting for confounding factors, worse LSDI sexual function score was strongly associated with worse Oswestry Disability Index, Scoliosis Research Society-22r total, and SF-36 Physical Component Summary and Mental Component Summary scores at both baseline and 2-year follow-up (p<0.05 for all comparisons). Predictors of poorer baseline sexual function included older age, increased SVA, and increased back pain (p<0.05 for all comparisons). Predictors of improvement in sexual function at 2-year follow-up included sagittal vertical axis improvement (P = 0.0032) and decreased postoperative back pain (P < 0.0001)., Conclusions: This study found that sexual dysfunction scores due to lumbar stiffness significantly improved after surgery for ASD. Additionally, lumbar stiffness-related sexual dysfunction is strongly related to overall outcome measured by Oswestry Disability Index and Scoliosis Research Society-22r total score, highlighting the importance of sexual health on overall outcome in ASD patients., (Copyright © 2020 Elsevier Inc.
