STUDY DESIGN  Prospective cohort study. CLINICAL QUESTION  Does the patients' body mass index (BMI) influence the degree of intraoperative lumbar lordosis in patients undergoing operative treatment on the Mizuho Orthopedic Systems Incorporated (OSI) Jackson spinal table? METHODS  Twenty-four consecutive patients undergoing posterior spinal instrumentation and fusion on the Jackson table, ex...

[Purpose] The purpose of this study was to document the effect of individual strengthening exercises for posterior pelvic tilt muscles on back pain, pelvic tilt angle, and lumbar ROM of a low back pain (LBP) patient with excessive lordosis. [Subjects] The subject was a 28 year-old male with excessive lordosis who complained of severe LBP at the L3 level. [Methods] He performed individual streng...

PURPOSE Barefoot running (BF) is gaining popularity in the running community. Biomechanical changes occur with BF, especially when initial contact changes from rearfoot strike (RFS) to forefoot strike (FFS). Changes in lumbar spine range of motion (ROM), particularly involving lumbar lordosis, have been associated with increased low back pain. However, it is not known if changing from RFS to FF...

STUDY DESIGN Prospective observational study. PURPOSE To introduce the techniques and present the surgical outcomes of mini-open anterior lumbar interbody fusion (ALIF) at the most caudal segments of the spine combined with lateral lumbar interbody fusion (LLIF) for the correction of adult spinal deformity. OVERVIEW OF LITERATURE Although LLIF is increasingly used to correct adult spinal de...

The goal of any ambulatory patient is to maintain a horizontal gaze with the least amount of energy expenditure. With progressive deformity, and in particular sagittal malalignment, significant compensatory mechanisms must be used to achieve this goal. Each pelvis dictates the amount of lumbar lordosis required through its morphometric parameter pelvic incidence. The pelvis may compensate for d...

OBJECTIVE: To analyze the radiological outcomes of using LLIF technique to treat adjacent-level disease. METHODS: Patients undergoing surgery for treatment adjacent level disease, with preoperative radiography and postoperative at 3 months 1 year follow-up, who had completed informed consent form were included. whose radiographs did not allow measurements proposed in study be performed excluded...

[Purpose] This study aimed to determine the prevalence and characteristics of hyperkyphosis in male university students. [Participants Methods] The angles thoracic kyphosis, upper spine, lower lumbar lordosis, sacral tilt 100 students were measured standing position using a Spinal-Mouse®. [Results] subjects with 40° or greater was 45% (45/100 subjects). kyphosis angle used divide into group nor...

The purpose of this study was to determine whether lower body negative pressure (LBNP) treadmill exercise maintains lumbar spinal compressive properties, curvature, and back muscle strength after 28 days of 6 degrees head-down tilt (HDT) bed rest (BR). We hypothesize that LBNP treadmill exercise will maintain lumbar spine compressibility, lumbar lordosis and back muscle strength after 28 days o...
