ABSTRACT
Intraoperative periprosthetic humeral fractures are a rare but debilitating complication of reverse shoulder arthroplasty and can occur during multiple stages of the procedure. Prior biceps tenodesis has been found to reduce cortical humeral strength and predispose the patient to humeral fracture. We present a case of a 68-year-old female with a previous history of biceps tenodesis due to an irreparable rotator cuff tear. Months later, and after symptoms persisted, a reverse shoulder arthroplasty was performed. During the surgery and while performing final reduction, a fracture line was observed involving the hole used for the previous tenodesis procedure. The fracture was repaired, and the patient reported favorable outcomes. We report several factors that might have contributed to sustenance of this intraoperative fracture including prior biceps tenodesis, use of a press fit humeral stem, and the sex of the patient.
ABSTRACT
The effect of tea extract on the intestinal absorption of glucose and sodium was studied in rats. Tea extract reduced the mucosal uptake of glucose and its portal plasma concentration, but was without any effect on its serosal transport. The mucosal uptake of sodium was similarly inhibited. The tea extract reduced also the in vitro activity of the Na(+)-K+ ATPase in an intestinal mucosal homogenate. These data are consistent with the hypothesis that an active ingredient in tea reduced sodium extrusion from the enterocytes by inhibiting the Na(+)-K+ pump, thus destroying the gradient needed for the mucosal transport of glucose.
