Hypermobility 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 and blue signifying perichondrial vascularization and hyaline cartilage, respectively. Two model types are available for purchase: a two level (L3-L5) or three level (L2-L5). Each hypermobile (L3-4) motions segment is half the stiffness and demonstrates hypermobility compared to the other levels.
L3-L5 Model includes a hyperelastic L3-4 one-part intervertebral disc
L2-L5 Model includes a hyperelastic L3-4 one-part intervertebral disc with L4-5 and L2-3 of identical lesser elasticity (2x stiffness).
Custom orders available to include a two-part intervertebral disc (both nucleus and annulus) to demonstrate nuclear shifting and herniation. Inquire for pricing.
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.
