Abstract:

Object In the surgical treatment of spinal deformities, the importance of restoring lumbar lordosis is well recognized. Smith-Petersen osteotomies (SPOs) yield approximately 10° of lordosis per level, whereas pedicle subtraction osteotomies result in as much as 30° increased lumbar lordosis. Recently, selective release of the anterior longitudinal ligament (ALL) and placement of lordotic interbody grafts using the minimally invasive lateral retroperitoneal transpsoas approach (XLIF) has been performed as an attempt to increase lumbar lordosis while avoiding the morbidity of osteotomy.

Abstract:

Background: Body mass index (BMI) is an indicator of health that is often used with the ratio between body weight and height. Health problems related to BMI vary widely, including bone problems such as lordosis. Lordosis is a disorder that causes an abnormally enlarged curvature of the vertebrae or spine. This study aimedto review the correlation between BMI and lumbar lordosis curve. Methods: This study used a literature review design.The articles that discusses the correlation of BMI and increase in the lumbar lordosis curve based on secondary data from published literature on Google Scholar

This study aims to assess the differences in the radiological and clinical results depending on the lordotic angles of the cage in posterior lumbar interbody fusion (PLIF). We reviewed 185 segments which underwent PLIF using two different lordotic angles of 4° and 8° of a polyetheretherketone (PEEK) cage. The segmental lordosis and total lumbar lordosis of the 4° and 8° cage groups were compared preoperatively, as well as on the first postoperative day, 6th and 12th months postoperatively.

Abstract:

Back ground: Lumbar curvature carries the upper body weight and transfers it directly to the pelvis, which is of great significance. The structures in the lumbar region are one of the factors that affect the lumbar-pelvic balance, as well as the performance of lumbar lordosis and pelvic tilt. Also, weakness of abdominal, dorsal, and lumbar muscles has been considered as the most common factors increasing the lumbar curvature. Excessive lordotic curvature is also called hyperlordosis, hollow back, saddle back and swayback. Common cause of excessive lordosis includes tight low back muscle, exces

Abstract:

Object A primary consideration of all spinal fusion procedures is restoration of normal anatomy, including disc height, lumbar lordosis, foraminal decompression, and sagittal balance. To the authors' knowledge, there has been no direct comparison of anterior lumbar interbody fusion (ALIF) with transforaminal lumbar interbody fusion (TLIF) concerning their capacity to alter those parameters. The authors conducted a retrospective radiographic analysis directly comparing ALIF with TLIF in their capacity to alter foraminal height, local disc angle, and lumbar lordosis.

Abstract:

This study aimed to assess the association between smartphone use in the sitting posture and changes in thoracolumbar kyphosis, lumbar lordosis, and pelvic asymmetry in adolescents with low back pain (LBP). Twenty-five adolescents with LBP and 25 healthy adolescents participated in this study. They were instructed to sit on a height-adjustable chair with their hips and knees bent at 90° for 30 min in their usual sitting postures. Thoracolumbar kyphosis, lumbar lordosis, and pelvic asymmetry were measured using a three-dimensional motion capture system. Thoracolumbar kyphosis and lumbar lordosi

Abstract:

Background: Prolonged hours of sitting in sustained posture is a common job requirement of desk job workers. Potential risk of iliopsoas muscle shortening leading to lumbar hyperlordosis, which in turn may cause low-back pain was identified. Thus, this study determined association between iliopsoas muscle length and lumbar lordosis in desk job workers. Methods and Material: This cross-sectional study was conducted on forty-six desk job workers working for 5 hrs/day for at least 5 years. Workers were assessed for iliopsoas muscle length using Modified Thomas test and flexi-ruler was used to mea

Abstract:

Background: Adolescence is the period when postural changes occur, as it is a phase when the body develops and grows. It is also the most appropriate time to evaluate and detect postural problems, and preventive measures may help to avoid these possible changes. However, studies evaluating the postural changes in this age group are lacking. Objective: The objective of this study was to evaluate thoracic kyphosis and lumbar lordosis changes in the spine of 9th grade students at a state military school in Goiás, Brazil. Methods: A total of 113 students (54 boys and 59 girls) participated in the

Abstract:

The spinal column of humans possesses strategically placed concave and convex curves which work in harmony to give an upright posture. The inwardly concave curvature in the lumbar region of the spine is known as the lordosis and it plays a very important role in the formation of the posture of humans. Analysis of the human lordosis is of great importance as it has been shown to be a major factor in the onset of low back pain, and is of great importance in spinal reconstructive surgery, through which some form of repair can be done to the spinal column that has undergone some form of alteration

Background and Objectives: Angular modifications in the physiological curvatures of the spine have been associated with spinal dysfunction and altered biomechanics, which may contribute to musculoskeletal complaints. The main objective of this experimental study was to investigate the association between lumbar lordosis and thoracic kyphosis angles and muscle activations during three different lower back exercises. Materials and Methods: Participants were divided into a hyperlordotic lumbar angle group—with increased thoracic kyphosis (n = 11)—and a normal lordotic lumbar thoracic angle group

In this study, we designed a backpack that can reduce the moment arm of backpack load by placing the center of gravity of the backpack close to the axis of the spine. In order to investigate the effect of sagittal spinal alignment compared with the general backpack, we conducted the study using radiological images. The participants in this study were 18 adults (8 males and 10 females). The subjects participated in the experiment without carrying the backpack, wearing the normal backpack, and wearing a backpack designed to reduce the load moment arm by placing the center of gravity close to the

Abstract:

Background: Lumbar hyperlordosis is the most prevalent musculoskeletal postural deformity. Maintenance of normal limits of lumbar lordosis is necessary for obtaining an ideal posture. Literature suggests that poor posture results in fascial restriction in which the fascia reorganizes in response to tension. Gross myofascial release (MFR) combined with posterior pelvic tilting exercises proved to be beneficial in improving the lumbar range of motion. Three-dimensional (3D) MFR is a novel approach toward reducing fascial restrictions. However, the literature determining the effects of 3D MFR is
