This study investigated the use of the geometric alignment of two frontal lines (the sternum and abdominal) for predicting alignment of the thoracic and lumbar spines and for measuring wheelchair-seated posture. The sternum line connects the upper sternum point and the lower sternum point. The abdominal line connects the lower sternum point and the center point between the right and left anteri...

Objective: The effects of spinal rigidity correlate positively with low back pain. Although spine flexibility has also been considered important for preventing stress-related lumbar disorders, the effects of spinal rigidity on mechanical stress during lumbar motion have rarely been reported. Methods: A biomechanical investigation and finite element analysis were conducted to elucidate the effec...

OBJECTIVES To develop and validate a new method of predicting the neutral lumbar spine curve from external (non-invasive electrogoniometer) measurements. BACKGROUND Non-invasive techniques for lumbar spine geometry prediction suffer from a lack of a complete geometry description, problems with applicability to field conditions, or both. METHODS The study consisted of three steps. First, uti...

Extreme lateral interbody fusion (XLIF) has gained popularity among spine surgeons for treating multiple conditions of the lumbar spine. In contrast to the anterior lumbar interbody fusion (ALIF) approach, the minimally invasive XLIF approach affords wide access to the lumbar disc space without an access surgeon and causes minimal tissue disruption. The XLIF approach offers many advantages over...

Concomitant spine and hip disease in patients undergoing total hip arthroplasty (THA) presents a management challenge. Degenerative lumbar spine conditions are known to decrease lumbar lordosis and limit lumbar flexion and extension, leading to altered pelvic mechanics and increased demand for hip motion. In this study, the effect of lumbar spine disease on complications after primary THA was a...

OBJECTIVE To chronicle the conservative treatment and management of an osteoporotic patient presenting with acute back pain resulting from a lumbar compression fracture. CLINICAL FEATURES A 74-year old male presented with acute back pain in the thoracolumbar region after an episode of lifting. Radiographic evaluation revealed generalized demineralization and a moderate wedge compression fract...

Background: During lactation, metabolic changes in the bone in different areas of the body may affect the amount of bone mineral density.The aim of this study was to determine the relationship between breastfeeding and bone mineral density in women. Materials and Methods:  In this study, articles were searched at Cochran, Medline (via PubMed), Scopus, and Web of Science databases until June 201...

Introduction It has long been said that exercise-based rehabilitation for scoliosis is ineffective, however, these reports studied general exercises. This case report is a prospective one-year follow-up of a nearly skeletally mature adolescent female (Risser 4) with idiopathic scoliosis treated with Pattern-Specific-Scoliosis Rehabilitation (PSSR). Methods The 15-year old patient recommended ...

Besides the study on examining facet joints of lumbar spine by ultrasound in normal population, there has not been any related report about examining normal facet joints of lumbar spine by ultrasound so far. This study was aimed to explore the feasibility of ultrasound assessment of lumber spine facet joints by comparing ultrasound measure values of normal and degenerative lumber spine facet jo...
