[Q]: Abstract: A retrospective review of the cases of 180 patients who had 198 acute open fractures of the tibial shaft and were admitted to a multiple-trauma referral center over a three-year period revealed an incidence of accompanying compartment syndrome of 9.1 per cent (eighteen fractures in sixteen patients). Each of the eighteen compartment syndromes was documented by measurements of intracompartmental pressure that were obtained by the saline-injection technique, and all were treated by four-compartment fasciotomy. The incidence of compartment syndrome was found to be directly proportional to the degree of injury to soft tissue and bone; this complication occurred most often in association with a comminuted, grade-III open injury to a pedestrian. The physician must maintain a high index of suspicion to detect a compartment syndrome in the patient who has multiple trauma, as its clinical signs and symptoms may be masked by a closed injury of the head or the need for ventilatory support or prolonged anesthesia for other surgical procedures.

[Q]: Abstract: Magnetic resonance imaging (MRI) is a powerful new tool for the study of human anatomy and pathology. By various MRI techniques, the structure of the middle and inner ears of aborted 20-week fetuses is defined and compared to gross anatomic sections. MRI's potential for evaluating temporal bone development and diseases of the ear is discussed.

[Q]: Abstract: Bone loss developing after cessation of ovarian function in humans represents a major health problem. To establish the value of ovariohysterectomy in female beagle dogs as a model for bone loss and to study static and dynamic parameters of bone associated with the negative bone balance occurring after cessation of ovarian function, we performed iliac crest bone biopsies before and 4 months after ovariohysterectomy in eight beagle dogs and in five sham-operated controls. Cessation of ovarian function was documented by an increase in serum levels of LH 4 weeks after ovariohysterectomy. There was no change in serum calcium, phosphorus, and creatinine during the 4 months of the study. Cancellous bone mass and trabecular mean wall thickness decreased significantly after ovariohysterectomy (P less than 0.01). In addition, the number of osteoblasts was increased and the bone formation rate per osteoblast, that is, the activity of bone-forming cells, was decreased (P less than 0.01). Parameters of bone resorption were not significantly altered in the animals with ovariohysterectomy. No changes in histomorphometric parameters of bone structure, formation or resorption were observed in the sham-operated controls. These data indicate that ovariohysterectomy in beagle dogs may serve as a useful model for bone loss associated with cessation of ovarian function. Osteoblastic insufficiency appears to play a major role in the maintenance of bone loss occurring after ovariohysterectomy in beagle dogs.
