title: [Clinico-pathogenetic variants of the piriform muscle syndrome].
abstract: The method of diagnosis of pathogenetic variations or musculus piriformis syndrome (MPS) by means of computer tomography is described. 24 patients with early signs of lumbar osteochondrosis and MPS were examined. Two variations of MPS with specific clinical and tomographic features were revealed, namely: an early spastic (functional) type and degenerative-dystrophic one. The peculiarities of muscles (diameter, location, density) and of adjacent pelvic structures were investigated in 15 healthy controls. Differentiated treatment of MPS permitted to control the pain and to promote other clinical signs regression faster than conventional therapy.
