The uncemented porous-coated anatomic total hip prosthesis. Two-year results of a prospective consecutive series.

摘要: Fifty uncemented porous-coated total hip prostheses were implanted in forty-seven patients whose mean age was fifty-eight years. Clinical hip-rating scores, as described by Harris, determined and anteroposterior frog-leg lateral radiographs made preoperatively, shortly postoperatively, at three months, six one year, two years postoperatively. The score 92 points (range, 74 to 100 points) year 69 thigh slightly painful nine (18 per cent) eight (16 Fourteen hips (28 (in thirteen patients) caused a moderate or severe limp postoperatively; however, this complication appears have been related more the direct approach that used than prosthesis.
