STUDY DESIGN A retrospective cohort study. OBJECTIVE The objective of this study is to compare the radiographic and clinical outcomes of transforaminal lumbar interbody fusion (TLIF) with bilateral facetectomy (BF) versus unilateral facetectomy (UF). SUMMARY OF BACKGROUND DATA BF is a surgical technique utilized with the intent of creating a greater degree of segmental lordosis than UF alon...

BACKGROUND Previous studies report an increase in thoracic kyphosis after anterior approaches and a flattening of sagittal contours following posterior approaches. Difficulties with measuring sagittal parameters on radiographs are avoided with reformatted sagittal CT reconstructions due to the superior endplate clarity afforded by this imaging modality. METHODS A prospective study of 30 Lenke...

Posture to avoid hyperextension of the lumbar spine during isometric trunk muscle exercises has been widely recommended. However, there are no common standards for cervical and pelvic alignment during exercises. To investigate the effects of four different techniques regarding cervical and pelvic alignment, electromyographic (EMG) and radiological studies were performed on 30 healthy subjects. ...

The aim of this study was to investigate joint mobility, segmental and general spinal mobility and their interrelationship in 607 women working as homecare personnel. Joint mobility (mainly peripheral) was estimated using the "Beighton" score. Spinal posture and mobility were measured by Debrunner's kyphometer. Passive segmental mobility and pain provocation were estimated manually. Reliability...

It has become increasingly clear in the past decade that local, regional, and global sagittal alignment of the spinal column is strongly correlated to both quality of life assessments and also the results of spinal surgical interventions. Traditional open spinal reconstructive procedures have emphasized these sagittal parameters recently, correlating to successful radiographic and clinical resu...

STUDY DESIGN Technical report on cadavers. OBJECTIVE To evaluate preliminary feasibility and safety of lumbar sagittal alignment correction with anterior hyperlordotic cages used to overpower previous posterior spinal instrumentation. METHODS Hyperlordotic 30° anterior lumbar interbody fusion (ALIF) cages were inserted in collapsed L5-S1 disc space of 2 cadavers to overpower prior posterior...

Purpose: Postural abnormalities, such as forward head posture (FHP), posterior kyphosis, and lumbar lordosis, can lead to discomfort health problems. This cross-sectional study was conducted investigate the prevalence of these abnormalities their association with age, body mass index (BMI), physical activity among male students Tehran universities. Methods: A on 400 University Medical Science e...
