What is lumbar degenerative disc disease, its causes and treatment available?
Lumbar Degenerative Disk Disease As humans age, they endure both macrotraumas and microtraumas and undergo changes in body habitus that alter and redistribute biomechanical forces unevenly on the lumbar spine. Natural progression of degeneration of the lumbar segment with motion proceeds with characteristic anatomic, biomechanical, radiologic, and clinical findings in lumbar degenerative disk disease (LDDD). Pathophysiology Posterior elements of the lumbar spinal functional unit typically bear less weight than anterior elements in all positions. Anterior elements bear over 90% of forces transmitted through the lumbar spine in sitting; during standing, this portion decreases to approximately 80%. As the degenerative process progresses, relative anterior-to-posterior force transmission approaches parity. The spine functions best within a realm of static and dynamic stability. Bony architecture and associated specialized soft tissue structures, especially the intervertebral disk, provide
