Instability Lumbar Model
Each model includes identical size and texture of real bone. Each vertebra is opaque light brown colour with elastomeric intervertebral discs. The facets surfaces have been painted with red signifying perichondrial vascularization and covered with an elastomeric white hyaline cartilage, respectively. However, at the L3-4 level, the facets are red only, providing a visual for active inflammation at the hypermobile level.
L2-L5 Model includes a hyper-elastic L3-4 one-part intervertebral disc
Research has revealed how aberrant motion can affect the dynamics of an adjacent functional spinal unit. This model has been constructed to show a patient what relative instability looks like with dynamic disc micro-movements of sheer instability as the facets approximate. Engage with patients who display hypermobility symptoms to encourage self-management of practices that improve the condition like in the case of core stabilization exercises.
