Architectural Analysis and Intraoperative Measurements Demonstrate the Unique Design of the Multifidus Muscle for Lumbar Spine Stability

✓The goal of this study was to establish a much less invasive method for access to the lateral lumbar spine for posterolateral fusion and pedicle screw (PS) placement. The technique was developed through knowledge of the anatomy literature and the author's clinical experience in more than 90 completed cases. The lateral intramuscular planar approach provides a much less invasive access to the lateral aspect of the lumbar spine and sacrum. An invariant intramuscular plane, poorly described in the anatomical literature, is ideal for postero-lateral fusion and/or PS placement from L-3 caudally. The approach requires essentially no resection of the multifidus muscle, or of the pars thoracis of the erector spinae.

Vertebral Degeneration

Insufficient exploration of the dependence between diseases of degenerative bones and the range of motion (ROM) during torsion, flexion and lateral bending limits further understanding about the lumbar biomechanics and treating of the lumbar related dysfunction. The objective of this study was to determine the effect of vertebral degradation on the instability of spine 2 motion L2–L4 segments during torsion, flexion and lateral bending by the finite element method (FEM). Three different 3D FE models comprising the healthy state and the degradation of trabecular bone and cortical bone were developed. Nonlinear numerical analyses of lumbar spine stability discovered that osteoporotic degradation can lead to critical segmental ROM and intervertebral shearing values, which results in the loss of spine stability for the case of flexion loading. Instability is caused by microscopic changes in the thickness of cortical shell. This analysis of the intervertebral shearing and ROM may be further used to diagnose such translation abnormalities like hypomobility or hypermobility.
