The non-suppurative, non-inflammatory disease of the anterior pelvic girdle which occurs in the female appears to be a variant of the more common disease which occasionally follows suprapubic prostatectomy in men. Treatment should be symptomatic, although x-ray therapy, cortisone, ACTH, and possibly phenylbutazone may be of value. The disease is self-limiting, and the authors do not believe that in their cases infection played any part.
