HUETER-VOLKMANN LAW


According to Hueter-Volkmannn Law, bone growth in the period of skeletal immaturity is retarded by mechanical compression on the growth plate and accelerated by growth plate tension.

Hueter-Volkmann LawHueter-Volkmann law is generally used to explain mechanism of scoliosis. Because of the physiologic curvature in the normal thoracic spine, compressive force is delivered on the ventrally located part of the vertebral column, whereas distractive force is delivered on the dorsally located part.
The process leading to abnormal spinal curvature is thought to be initiated by the rotation of vertebral bodies in the axial plane, which causes discrepant axial loading between the ventrally and dorsally located portions of the involved vertebrae. Over time, the discrepancy manifests as a change in the directionality of spinal curvature; that is, the ventrally located part of the vertebral column becomes the concave side and the dorsally located part becomes the convex side of a lateral curve.
As a result, compression exerted on the vertebral growth plates at the predetermined concave side of curvature causes growth to slow, while traction exerted on the growth plates at the predetermined convex side of curvature causes growth to accelerate.
