説明

A pressure pain, frequently associated by an induration, is usually perceptible in the suprascapular region of the normal subjects. We considered the relation of the pressure pain with the anatomical structures of that region, firstly by investigating the locus of the pressure pain and whether it is associated by an induration or not, using the living subjects and in several cases, followed by a X-ray examination of the final destination of the needle which was inserted in the pressure pain zone; and lastly by dissecting the anatomical structures penetrated by that needle in a woman's cadaver.<br>We obtained the follwing three results from the above investigation and observations. (1) The most conspicuous pressure pain was perceptible in the middle of the upper margin of the suprascapular region, and a long and slender induration extending sagitally was palpable there. (2) The second rib lay in the deepest layer of the pressure pain zone, the layer which were overlain by the serratus posterior superior muscle, the serratus anterior and the omohyoid, many branches of the transversus colli artery and vein and the accessory nerve, and the trapezius muscle with the posterior suprascapular nerves running on its superficial surface, in order of lower to upper layer. (3) The transversus colli vessels, which forms a complex network of branchings crossing sagitally above the second rib, was suggested to have some relationship to the occurence of the pressure pain associated by the induration, because only the formation of such vascular network was peculiar to the pressure pain zone.
