Adjacent Vertebral BMD Decline After Lateral Lumbar Interbody Fusion

Orthopaedic Surgery, EarlyView.
To investigate the changes in the volumetric bone mineral density (vBMD) of the adjacent vertebral cancellous bone and endplate at the fusion level in patients undergoing lateral lumbar interbody fusion (LLIF). The vBMD of the cancellous bone and endplates adjacent to the vertebral body, cephalad or caudal to the fused level, decreased after LLIF. vBMD

Motion characteristics of the vertebral segments with lumbar degenerative spondylolisthesis in elderly patients [PDF]

, 2016
Objective Although some studies have reported on the kinematics of the lumbar segments with degenerative spondylolisthesis (DS), few data have been reported on the in vivo 6 degree-of-freedom kinematics of different anatomical structures of the ...

Accuracy of a table‐bound reduction and drill guide system for minimally invasive sacroiliac screw placement in cats

Veterinary Surgery, EarlyView.
Abstract Objective To describe the equipment and accuracy of a table‐bound reduction system and three‐dimensional (3D) printed drill guide for fluoroscopically guided, minimally invasive sacroiliac luxation (SIL) reduction and stabilization by means of a single iliosacral lag screw in cats. Study design Retrospective case series.

50% body weight loading reduces stature increases and lumbar disc expansion from 4 h hyper‐buoyancy floatation versus 15 min sitting upright

Experimental Physiology, EarlyView.
Abstract Microgravity is associated with stature increases, back pain and post‐flight intervertebral disc (IVD) herniation. This study aims to determine whether 30 s seated 50% body weight (BW) axial loading is comparable to 15 min sitting upright in 1 g upon changes in stature, anterior lumbar IVD height (via ultrasound), passive vertebral stiffness ...

Vertebral Growth Modulation Through Periosteal Resection and Fixed Length Deformity Overcorrection: Computational and In Vivo Pilot Study

JOR SPINE, Volume 8, Issue 4, December 2025.
The feasibility of using growth promoting strategies (vertebral periosteal resection and distraction) was investigated via computational and in vivo analysis. Computational analysis demonstrated that there is an increasing mechanical benefit to utilizing concave distraction over convex compression during spinal deformity correction.

Age and Spinal Level as Predictors of Lumbar Disc Degeneration in Humans and Mice: A Comparative Analysis

JOR SPINE, Volume 8, Issue 4, December 2025.
Mouse models are commonly used to study IVD degeneration and related neurological conditions that especially impact elder population. However, how well mice replicate human pathology remains unclear. This study compared lumbar IVD degeneration patterns across age and spinal levels in humans and mice.

Injury Induces More Severe Biomechanical Changes in Middle‐Aged and Geriatric Lumbar Spines in a Mouse Ex Vivo Model

JOR SPINE, Volume 8, Issue 4, December 2025.
Injury and age exhibited an interactive effect, resulting in greater biomechanical dysfunction in middle‐aged (12 months) and geriatric (24 months) mouse intervertebral discs (IVDs), associated with age‐related proteoglycan loss and collagen denaturation as shown by FTIR and histological analyses.

A novel methodology for measurement of the intradiscal pressure and height disc variation of intervertebral disc under compression [PDF]

, 2013
The intervertebral disc (IVD) is subjected to several types of loading during daily routine events. However, the overloading on this structure induces higher intradiscal pressure (IDP), which could cause severe damage on its structure.
