Introduction: One of the causes of low back pain is lumbar hyperlordosis. There are different protocols of therapeutic exercises for its correction, which do not involve all of corporal segments. A modified protocol is proposed, which involves all such segments.
Objective: To evaluate the efficacy of proposed protocol with two established protocols for correction of lumbar hyperlordosis.
Materials And Methods: Simple-blind clinical trial on 42 students of the Faculty of Medicine at University of Colima. The three protocols: A) Pérez-Olmedo (proposed, n = 14), B) Williams (n = 15) and C) Jeffrey Saal (n = 13) were randomly assigned. Clinical and radiological evaluations were performed. Lumbar hyperlordosis was considered when Ferguson's angle was > or = 30 degrees, measured on lateral spine x-ray pictures. During two months they underwent supervised and directed exercise sessions. The improvement in lumbar hyperlordosis correction of each protocol was compared through paired Student t-test and ANOVA.
Results: Average age was 18 +/- 0.9 years. Lumbar hyperlordosis frequency was 31% (n = 15). There was not significative difference on Ferguson's angle average comparation between three treatment groups. There was lumbar hyperlordosis improvement with following percentages: group A = 60%, Group B = 16% and group C = 0%.
Conclusion: Protocol of therapeutic exercises proposed (Pérez-Olmedo) could be an alternative to lumbar hyperlordosis improvement in asyntomatic youhts.

Background: High-grade Isthmic Spondylolisthesis often requires surgical intervention for spinal realignment and decompression. This study describes a modified Bohlman procedure utilizing robotic-assisted navigation and a Globus SI-LOK interbody device.
Methods: A retrospective review was conducted on three patients who underwent the modified Bohlman procedure for high-grade spondylolisthesis at a single hospital between 2022 and 2023.

Introduction: In asymptomatic subjects, variations of sagittal alignment parameters according to age and pelvic incidence (PI) has been reported. The aim of this observational study was to describe thoraco-lumbar sagittal alignment in patients with degenerative scoliosis and to compare them to asymptomatic individuals, seeking for the specific effect of deformity in similar age and PI groups.
Materials And Methods: Full spine radiographs of 235 asymptomatic subjects and 243 scoliosis patients were analyzed: cervico-thoracic inflexion point (CTIP), thoraco-lumbar inflexion point (TLIP), lumbar lordosis (LL) L1-S1, LL (TLIP-S1), LL superior arch (TLIP-lumbar apex), LL inferior arch (lumbar apex-S1), PI, thoracic kyphosis (TK) T5-T12, TK T1-T12, number of vertebrae CTIP-TLIPandTLIP-S1.
Comparison of Clinical and Radiological Outcomes of Three-Column Lumbar Osteotomies with and without Interbody Cages for Adult Spinal Deformity.

International Spine Study Group Foundation, Denver, Colorado, USA.
Background Context: Correcting sagittal malalignment in adult spinal deformity (ASD) is a challenging task, often requiring complex surgical interventions like pedicle subtraction osteotomies (PSOs). Different types of three-column osteotomies (3COs), including Schwab 3, Schwab 4, Schwab 4 with interbody cages, and the "sandwich" technique, aim to optimize alignment and fusion outcomes. The role of interbody cages in enhancing fusion and segmental correction remains unclear.

Background: Pediatric lumbar spondylolysis (LS) is common in junior and senior high school athletes. Lower LS (L4-L5 level) is more common in children, and upper LS (L1-L3 level) is relatively rare; therefore, the pathogenesis of upper LS remains unclear.
Purpose: To elucidate the mechanisms of upper LS by identifying and comparing characteristics between upper and lower LS cases.
The Spine Lengthens During Walking in Healthy Participants, with Age-Related Changes in Kinematic Parameters.

While the importance of the upper and lower limbs in locomotion is well understood, the kinematics of the trunk during walking remains largely unexplored. Two decades ago, a casual observation was reported indicating spine lengthening in a small sample of mostly children during walking, but this observation was never replicated. Objectives: This study aims to verify the preliminary observation that spine lengthening occurs during walking and to explore changes in spine kinematics across three different age groups.
