Valgus and Varus Alignment

Valgus and varus describe the alignment between two anatomical segments.  Valgus  refers to outward angulation of the distal segment of a bone or joint.  Varus is the opposite of valgus and refers to inward angulation of the distal segment of a bone or joint. To better understand these concepts, see the  illustration below.   A line is drawn along the long axis of the proximal segment.  Another line is drawn along the long axis the distal segment.  When comparing the two lines,  focus on the the distal segment’s alignment with respect to the proximal segement. valgus2

 The illustration on the left depicits valgus in which the distal segment of the joint is angulated outward.

The illustration on the right is an example of varus.varus-alignment

What is the significance?    Look at the x-rays below.valgus-x-ray1

 

Misalignment of one bone in relation to other places disproportionate forces on the joint with resultant excessive wear and tear on the meniscus, ligament and cartilage.  At the Centeno-Schultz Clinic we emphasis correct joint aligment through various therapies including IMS, prolotherapy, physical therapy and the use of unloader braces.  If there has been excessive wear of the cartilage,  there is a novel technique which allows patients to use there own stem cells.
