By measurement of intradiscal pressure in vitro, the hydrostatic properties of the nucleus pulposus of normal lumbar intervertebral disc were proven. The hydrodynamic properties seem to exist also in the somewhat degenerated disc, but not in the more severely deranged ones.

MEASUREMENT OF INTRADISCAL PRESSURE By ALF NACHEMSON The nucleus pulposus consists of a three dimensional network of collagen fibres, enmeshed in a mucoprotein gel which contains various mucopolysaccharides (Hirsch, Paulson, SylvCn & Snellman ; Bernardi, Happey & Naylor).

Intradiscal pressure measurement was performed by connecting a cannula inserted into the patient's L4-5 disc space to a pressure transducer. The influences of age, sex, disc level, and degree of degeneration on the mechanical behavior of 42 fresh cadaver lumbar motion segments are reported.

In the mid-1950s Alf Nachemson was given an assistant research position under Professor Carl Hirsch at Uppsala University Hospital. To study the loading conditions of the human spine he developed a method for intradiscal pressure measurements. Intravital Dynamic Pressure Measurements in Lumbar Discs: A Study of Common Movements, Maneuvers and Exercises Issue 1 of Scandinavian journal of rehabilitation medicine: Supplement, ISSN 0346-8720: Authors: Alf Nachemson, Gösta Elfström: Publisher: Almqvist & Wiksell, 1970: Original from: the University of Michigan: Digitized: Aug 13, 2008 Lying supine was measured to be 0.10 MPa and lying supine with knees slightly flexed was the lowest recorded value of 0.09 MPa. Sneezing while lying laterally increased pressure to.38 MPa, much higher than the 0.15 MPa caused by laughing while lying laterally.
