Complete absence of the lumbar spine and sacrum.

Three additional patients with absence of the lumbar spine and sacrum have been subjected to subtrochanteric amputations and rehabilitation by prosthetic fitting and training. Gross and histological findings of surgical and autopsy specimens have been presented. Conjectures have been presented relative to the mechanisms responsible for the severe deficit indicating the role of induction mechanisms present in the differentiating embryo. The etiologic factor or factors are unknown.

Non-Suppurative Osteitis Pubis in the Female

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.

An improved spine retractor.

I have attempted to discuss the preventive aspects of running injuries, the use of orthotic devices and their indications, the use of standard physiotherapeutic techniques, medications, injections, and finally surgery in the prevention of running injuries. Return to running and faulty training techniques have also been mentioned.
