background carrying heavy backpacks by school students at growth age can cause irreversible physical harms. this study aimed to investigate the relationship between backpack weight and the incidence of lordosis, kyphosis, scoliosis, and dropped shoulders in elementary school students. materials and methods this descriptive-analytical study was conducted in 2015 in abadan, iran, and 383 elementa...

AIM OF THE STUDY To assess the validity of the sitting position when testing lumbar braces for the maintenance of lordosis. PATIENTS AND METHODS Twelve young adult subjects participated in the experiment, in which they were seated on force platform. The four experimental conditions (with or without a brace and with or without enforced lordosis) were chosen in order to distinguish between the ...

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...

A retrospective analysis of 500 patient radiographs was conducted to measure the clinical correlation of cervical lordosis measurements and incidence of motor vehicle accident (MVA). Five hundred lateral cervical radiographs were selected at random from the practice of one of the authors (DLM). The C1-7 angle of the cervical curve was then measured by two blinded examiners. Inter-examiner relia...

BACKGROUND CONTEXT: Lateral approach to lumbar fusion has been gaining popularity in recent years. It utilises a retroperitoneal transpsoas approach to reach the disc space in a minimally invasive fashion. It allows better access for disc clearance and insertion of large foot print cages. PURPOSE: To compare radiographic and clinical results following lateral lumbar interbody fusion (LLIF) and ...

STUDY DESIGN Retrospective radiographic analysis. OBJECTIVE To determine which lumbar interbody technique is most effective for restoring lordosis, increasing disk height, and reducing spondylolisthesis. SUMMARY OF BACKGROUND DATA Lumbar interbody fusions are performed in hopes of increasing fusion potential, correcting deformity, and indirectly decompressing nerve roots. No published study...

BACKGROUND The sagittal alignment of the spine changes depending on body posture and degenerative changes. This study aimed to observe changes in sagittal alignment of the lumbar spine with different positions (standing, supine, and various sitting postures) and to verify the effect of aging on lumbar sagittal alignment. METHODS Whole-spine lateral radiographs were obtained for young voluntee...

OBJECTIVE This study investigates the impact of isometric contraction of anterior cervical muscles on cervical lordosis. METHODS 29 volunteers were randomly assigned to an anterior head translation (n=15) or anterior head flexion (n=14) group. Resting neutral lateral cervical x-rays were compared to x-rays of sustained isometric contraction of the anterior cervical muscles producing anterior ...

STUDY DESIGN A cross-sectional, descriptive study. PURPOSE This study aimed to investigate the relationship between kyphosis and lordosis measured by using a flexible ruler and musculoskeletal pain in students of Hamadan University of Medical Sciences. OVERVIEW OF LITERATURE The spine supports the body during different activities by maintaining appropriate body alignment and posture. Normal...
