STUDY DESIGN: Survey. OBJECTIVE: To define the critical elements of common spine surgeries. SUMMARY OF BACKGROUND DATA: Despite significant relevance to the field of spine surgery, the term "critical element" of surgery has not been clearly defined. Every surgical procedure involves numerous steps, each with its own potential for complications and harm to the patient. Despite its crucial role in surgical training, billing, and the ethicality of concurrent surgery, the term "critical element" of surgery has not been defined...

Prone planking exercises have been used by rehabilitation professionals to activate torso muscles in healthy persons and those with low back pain. The aim of this study was to compare the magnitude of electromyographic (EMG) muscle activation from 10 right-sided muscles as demonstrated by the percentage of maximum voluntary isometric contraction (%MVIC) during four planking procedures. Surface EMG activity was acquired from the following muscles: (1) iliocostalis lumborum (IL), (2) longissimus thoracis (LT), (3) lumbar multifidus (LM), (4) rectus abdominis (RA), (5) external oblique (EO), (6) internal oblique (IO), (7) serratus anterior (SA), (8) latissimus dorsi (LD), (9) hamstrings (HS), and (10) gluteus maximus (GM)...

BACKGROUND: Androgen deprivation therapy (ADT) is an effective treatment for men with advanced prostate cancer, but loss of bone mineral density (BMD) is a major risk factor for fractures. This analysis evaluated the relative effectiveness of osteoporosis treatments using BMD as a surrogate endpoint for fragility fractures in men on continuous ADT. METHOD: We included randomized controlled trials studying bisphosphonates, denosumab, toremifene, and raloxifene in patients with non-metastatic prostate cancer on ADT for review...

In this large registry-based study, women with diabetes had marginally greater bone mineral density (BMD) loss at the femoral neck but not at other measurement sites, whereas obesity was not associated with greater BMD loss. Our data do not support the hypothesis that rapid BMD loss explains the increased fracture risk associated with type 2 diabetes and obesity observed in prior studies. INTRODUCTION: Type 2 diabetes and obesity are associated with higher bone mineral density (BMD) which may be less protective against fracture than previously assumed...

Study Design Longitudinal cohort study. Background Spinal pain is responsible for a huge personal and societal burden but the aetiology remains unclear. Deficits in motor control have been implicated with spinal pain in adults, and delayed motor development is associated with a range of health problems and risks in children. Objectives To assess whether there is an independent relationship between the age at which infants first sit and walk without support, and spinal pain at age 11 years. Methods Data from the Danish National Birth Cohort were analysed...

OBJECTIVE: Since its introduction and FDA approval, rhBMP-2 has been adopted by spine surgeons as a substitute for ICBG in numerous spinal fusion techniques. As broad clinical use increased, reports on potential complications associated with rhBMP-2 also increased. We provide our experience with TLIF using rhBMP-2 or ICBG in an entirely Hispanic population. METHODS: This was a 2-year retrospective study of 67 patients, with 26 in the rhBMP-2 group and 41 in the ICBG group, who underwent TLIF...

PURPOSE: Few studies have investigated the risk factors for implant removal after treatment for spinal surgical site infection (SSI). Therefore, there is no firmly established consensus for the management of implants. We aimed to investigate the incidence and risk factors for implant removal after SSI managed with instrumentation, and to examine potential strategies for avoiding implant removal. METHODS: Following a survey of seven spine centers, we retrospectively reviewed the records of 55 patients who developed SSI and were treated with reoperation, out of 3967 patients who had spinal instrumentation between 2003 and 2012...

Functional limb length discrepancy (LLD) in adolescents can result from soft tissue contracture following long-standing hip disease. We present a case of a 13-year-old girl with difficulty in ambulation due to right hip pain and LLD. Radiographs revealed severe arthritis of right hip with signs of avascular necrosis of the femoral head. The patient had developed reactive scoliosis of lumbar spine along with pelvic obliquity. After failing conservative management, total hip arthroplasty (THA) without attempting to equalize LLD was performed...

BACKGROUND: Impairment of spine rotation is a key concept in several theories explaining the pathogenesis and progression of scoliosis. In previous studies, a more limited range of motion in scoliotic girls compared to their non-scoliotic peers was noted. The Trunk-Pelvis-Hip Angle measurement is a test used to assess the range of motion in the trunk-pelvis-hip complex in the transverse plane. The aim of this study was to assess an immediate effect of Proprioceptive Neuromuscular Facilitation specific mobilization (mPNF) on the angle of trunk rotation and Trunk-Pelvis-Hip Angle range of motion in adolescent girls with double scoliosis...
