The influence of patient-related factors and the position of the acetabular component on the rate of dislocation after total hip replacement.
The senior one of us performed 438 primary and 181 revision total hip arthroplasties with use of so-called modern prostheses between July 1983 and January 1994.
Fifty-three patients, who had had forty-seven primary procedures and twelve revisions, either died or were lost to follow-up less than two years after the operation and were excluded from the study.
The results for the remaining 446 patients (391 primary procedures and 169 revisions) were analyzed to determine the influence of patient-related and operative factors and the position of the acetabular component on the rate of dislocation.
Dislocation occurred after thirty-two (6 per cent) of the 560 total hip arthroplasties : seventeen (4 per cent) of the 391 primary procedures and fifteen (9 per cent) of the 169 revisions (p=0.046).
There was no relationship between the variables of age, gender, obesity, or preoperative diagnosis and dislocation after either primary or revision arthroplasty.
Seven (23 per cent) of the thirty arthroplasties in the patients who had a history of excessive intake of alcoholic beverages (more than 2.1 liters [seventy-two ounces] of beer or more than 0.2 liter [six ounces] of other alcoholic beverages a day) were followed by a dislocation compared with twenty-five (5 per cent) of the 530 arthroplasties in the patients who did not have such a history.
This difference was significant for the patients who had had a revision arthroplasty (p=0. (...)
