Twenty consecutive primary noncemented total hip arthroplasties performed on 12 men with ankylosing spondylitis were available to be studied clinically and radiographically at an average follow-up period of 75 months (range, 27-121 months). The average patient age at the time of surgery was 35 years (range, 23-53 years). Harris hip scores averaged 48.4(More)
From a group of 643 total hip arthroplasties, 98 patients required trochanteric osteotomies, and in 68 the trochanteric osteotomies were repaired with the Dall-Miles cable grip system (Howmedica, Rutherford, NJ). Trochanteric nonunion occurred in 17 of these patients (25%), with fraying and fragmentation of the cable present in 15 (88%). Of the 51 patients(More)
One hundred and eighty-four patients who had been managed, between 1984 and 1985, with a total of 204 consecutive primary total hip arthroplasties with insertion of a Harris-Galante type-I acetabular component without cement were prospectively studied. There were eighty-two men (45 per cent) and 102 women (55 per cent). The mean age at the time of the(More)
One hundred and thirty-eight consecutive revisions of an acetabular component were performed in 132 patients between 1983 and 1986. The revision prosthesis was a hemispherical component that was coated with porous titanium mesh and was secured to the pelvis with a variable number of screws. There were seventy-five women and fifty-seven men, and the mean age(More)
Propofol has been proposed as a sedative agent during awake craniotomies. However, there are reports of propofol suppressing spontaneous epileptiform electrocorticography (ECoG) activity during seizure surgery, while others describe propofol-induced epileptiform activity. The purpose of this study was to determine if propofol interferes with ECoG and direct(More)
One hundred thirty-eight acetabular revisions for aseptic loosening were performed in 132 patients using a cementless hemispherical component coated with titanium mesh and inserted with supplemental screw fixation. Twelve patients died, 9 were lost to follow-up and 6 could not return, leaving 111 patients (115 hips) at mean 100 months follow-up. Thirteen(More)
The results of revision of the acetabular component without cement, performed for aseptic loosening, were reported previously after a mean of forty-four months for 138 hips (132 patients). After an additional mean duration of follow-up of almost five years, twelve patients (twelve hips) had died before they could be followed long enough for the later study(More)
One hundred fifty consecutive hybrid total hip arthroplasties in 139 patients were performed using an uncemented hemispheric porous coated acetabular component (HGP-I) with screws and a femoral component (Precoat) cemented with contemporary cementing technique. The average patient age was 67 years (range, 39-85 years). No patients were lost to followup.(More)
Ninety consecutive total hip arthroplasties in 73 patients with osteonecrosis of the femoral head yielded 81 hips in 64 patients (37 men and 27 women) available for evaluation after a 4-8-year follow-up period. The average age at surgery was 39.9 years (range, 20-66 years). Osteonecrosis etiology was idiopathic in 13 hips, alcohol-induced in 15, femoral(More)
We prospectively studied the intermediate-term results of forty-nine revision total hip arthroplasties without cement that were performed because of aseptic loosening of a cemented femoral component in forty-five consecutive patients; the mean duration of follow-up was sixty-five months (range, forty-five to eighty-seven months). A curved, long-stem,(More)
