STUDY DESIGN Exploratory study of regional muscle activity in different postures. OBJECTIVE To detail the relationship between spinal curves and regional muscle activity. SUMMARY OF BACKGROUND DATA Sagittal balanced spinal posture (C7 above S1 in the sagittal plane) is a goal for spinal surgery and conservative ergonomics. Three combinations of thoracolumbar and lumbar spinal curves can be ...

RATIONALE Lumbar degenerative scoliosis (LDS) is a common spinal disease for senior citizens. However, LDS accompanied with thoracic lordosis and lumbar kyphosis (LK) is rare in clinic. No reports have reported LDS with thoracic lordosis and LK. PATIENT CONCERNS A 54-year-old woman just complained about sever back pain without any radiculopathy and neurodeficit of low limb for 2 years, Visual...

STUDY DESIGN A retrospective radiographic study. PURPOSE To verify the correlation of sagittal and coronal plane changes after selective thoracic fusion in main thoracic (MT) adolescent idiopathic scoliosis (AIS). OVERVIEW OF LITERATURE Sagittal plane deformity is known to be essential in the evolution of scoliosis. METHODS Twenty-eight MT AIS patients treated by anterior selective thorac...

Some radiological features of the lumbar spine of 84 patients with spastic diplegia were compared with 50 control subjects. The average age of the patients was 20.1 years (3 to 39). Spondylolysis of the fifth lumbar vertebra was found in 21%, four times more frequently than in normal subjects. No patient under nine years of age had spondylolysis and the frequency increased with age. The average...

Background. Low back pain is a significant issue in the field of health. Therefore, addressing new therapeutic approaches seems necessary. Objectives. The present study examined the effect of combining core stability with stretching exercises on pain intensity and motor function in people with chronic nonspecific low back pain with and without hyperlordosis. Methods. The research method was q...

BACKGROUND Comparing movements/postures in people with and without lower back pain (LBP) may assist identifying LBP-specific dysfunction and its relationship to pain or activity limitation. This study compared the consistency in lumbo-pelvic posture and movement (range and pattern) in people with and without chronic LBP (>12 week's duration). METHODS Wireless, wearable, inertial measurement u...

OBJECTIVE Restoration of lumbar lordosis is a critical factor in long-term success after lumbar fusions. Transforaminal lumbar interbody fusion (TLIF) is a popular surgical technique in the lumbar spine, but few data exist on change in spinal alignment after the procedure. METHODS Eighty patients who underwent TLIF surgery were retrospectively reviewed (minimum follow-up period, 2 years). Sta...

OBJECTIVE Posterior accessed lumbar interbody fusion (PALIF) has a clear objective to restore disc height and spinal alignment but surgeons may occasionally face the converse situation and lose lumbar lordosis. We analyzed retrospective data for factors contributing to a postoperative flat back. METHODS A total of 105 patients who underwent PALIF for spondylolisthesis and stenosis were enroll...
