Two hundred eleven adult scapulae were examined and quantitative data pertaining to the dimensions of the suprascapular notch were obtained. Six types of suprascapular notch were observed. Transitions tended to occur between Types II, III, and IV. A classification function was developed utilizing the measured values of the dimensions of the suprascapular notch, which might help in assigning the scapulae to these transitional types. Dissections of the suprascapular area were performed in 15 cadavers. Static and dynamic relationships of the suprascapular nerve to the suprascapular foramen were examined.

Our previous work has shown that the addition of diphenhydramine hydrochloride to platelet-rich plasma is capable of causing disaggregation of platelet aggregates already induced by adenosine diphosphate as well as of inhibiting platelet aggregation when added prior to the aggregating agent. This led us to attempt to prevent arterial thrombosis in a canine experimental model. Ten dogs received an injection of diphenhydramine (approximately 3 mg/kg of body-weight) into the right common femoral artery 1 cm proximal to the proximal end of a 2 cm endarterectomy immediately after closure of the endarterectomy site and prior to performing an endarterectomy of the other common femoral and both common carotid arteries. The dogs which received diphenhydramine were compared with ten control dogs and found to have no protection against thrombosis at the sites of endarterectomy after 4 and 24 hours.
