title: [Long-term results using a Swanson silastic endoprosthesis of the metatarsophalangeal joint of the great toe. Discrepancy between clinical and radiologic findings].
abstract: 53 patients underwent 68 Swanson's Silastic prosthesis implantations in great toes from 1979-1984. 51 patients (96%) with 66 implantats were followed up from 1 to 7 years. The results of self-judgement and clinical examination at control were favourable, in contrast to the large number of unfavourable radiologic findings at control. Statistical analysis revealed a significant association between the number of weared prostheses with narrowing or fragmentation and increasing follow-up time (p = 0.04), but no significant association between the results of self-judgement and clinical examination and follow-up time.
