title: Survival of Lubinus straight (IP) and curved (SP) total hip prostheses in 543 patients after 4-13 years.
abstract: The clinical outcome and survival of 543 total hip arthroplasties with Lubinus cemented total hip prostheses after a mean of 7.9 years are reported. Clinical evaluation revealed no significant differences between patients with a straight stem and those with a curved anatomic stem. Loosening was statistically associated with young age, male sex, heavy weight, diagnosis other than osteoarthritis and year of operation. Survivorship analysis of the Lubinus IP implant at 8 years revealed a 95% chance of survival. The survival of the SP implant was 96%. After this time point the curve for SP implants began to fall at a faster rate than that for IP implants.
