Traumatic fibromyositis: a critical review of an enigmatic concept

Abstract

Traumatic fibromyositis is not an inflammation; there is no fever, leukocytosis or increased sedimentation rate; electrical characteristics and serum enzyme levels are within normal limits, and there are no observable pathologic alterations, although they have been carefully searched for. Recent attempts to express the effects of muscular sprain or strain as a biochemical disturbance expressed in an unusual pattern of lactate dehydrogenase isoenzymes appear not only to be technically flawed but inconsistent with results of conventional enzyme studies on other muscle and interstitial inflammations. In the author's view, "traumatic" fibromyositis is no more than a verbal construct arrived at by adding an adjectival modifier to the old terms for idiopathic rheumatic disorders. An examination of the evolution of the concept of traumatic fibromyositis shows that it lacks validity as a clinical diagnosis and ought to be abandoned.
