The presentation is based on the results of the nursing intervention program by using telephone contact to elderly patients with hip replacement after discharge.
All deceased were checked in the danish patient registration system for revision. 113 patients with 128 THR were operated with the Spotorno CLS stem, and 431 patients with 465 THR with the Mller straight stem. 270 patients with 297 THR were assessed radiographically and according to a modified Harris Hip Score (ROM was not used). Some were due to age or other illnes not able to attend the examination. If possible they were interviewed by telephone. The median age was 69,4 (range 18,3 – 88,1) for all, for the Spotorno CLS group 55 years (range 18–72) and for the Mller group 72 years (41–88). Male/female ratio: 0,56. Average follow-up was 13 years (range 9,1 -15.1). The primary diagnosis was osteoarthritis 538 hips, RA 10, fracture sequelae 15, congenital dislocation 14, others contributed with 16 hips. The survival rates were calculated using the Kaplan-Meier method.
After 13 years the survival rate for the cups was 96.8% including reoperations for polyethylene wear, for the femoral Mueller stem 90.7% and for Spotorno CLS 96.1 %
