The new Medial Branch Model (2020) uses our Professional LxH Model with two-level nerve details extending sensory branches to the L4 and L5 nerve roots. The new cauda equina (2020) has been updated to include the dura mater along with accurate rootlet number and geometry. Lumbar anatomy includes an inflamed facet capsule. Great for pain interventionalists in the education of medial branch blocks. Variations in modelling will exist as each model is handcrafted.
