Prosthetic replacement for pathological fractures of the proximal end of the femur: total prosthesis or bipolar arthroplasty?
We recommend bipolar arthroplasty rather than total hip arthroplasty in patients with a preoperative Karnofsky performance status index of more than 60 points if bone disease of the acetabulum is not evident on standard radiographs and if during operation the acetabular cartilage appears normal.
Partial outlet obstruction of rabbit bladders resulted in focal areas of moderate to severe hypoxia in the detrusor SM and subserosal regions concomitant with increased bladder mass, decreased contractile function, and selective metabolic dysfunctions of the SM consistent with an intermediate stage of decompensation. The metabolic characteristics of the normoxic mucosa were normal a were those of unobstructed bladders.
