title: [The PM-prosthesis].
abstract: The outcome of 114 PM-hip prostheses is reported, the mean time since operation of which is between 5 and 10.1 years (7.6 years mean). The fate of 23 hip replacements (10.1%) could not be evaluated. The scores of Merle d'Aubigné und Harris were used for evaluation. The mean score according to Merle d'Aubigné rose from 9.15 to 13.95 and that of Harris from 44.13 to 75.60. Subjectively 84 patients (73.7%) were fully satisfied with the outcome and 27 (23.6%) with limitations. In the patients opinion the state of the hip had improved 107 times (93.9%), twice (1.7%) it had deteriorated. 95 times (83.4%) the range of motion of the joint was found improved, 6 times (5.2%) the were regarded as deteriorated. The outcome is analysed in the line with the numerous criteria of the employed scores. Survival analysis suggests a 90.5% (confidence interval 86.3%-94.6%) probability of success of primarily implanted PM-Prostheses after 5 years and of 73.3% (confidence interval 60.3%-86.4%) after 10 years.
