title: [Capsulo-synovial lesions of the hip joint at the stage of total prosthesis implantation. Study based on 328 cases].
abstract: The authors have made a systematic study of specimens of synovium and capsule removed during total hip replacement for slowly and rapidly progressive arthritis, rheumatoid coxarthritis and necrosis. Out of 1 120 cases, there were 328 tissue samples suitable for satisfactory morphological interpretation. A number of conclusions are drawn from the detailed analysis of the different types of lesion. The vast majority of cases of common arthritis consist of hyperplastic and degenerative metamorphic lesions often associated with signs of inflammation. The dominant feature at this stage of coxarthritis is the histiocytic macrophage response to foreign bodies of bone and joint cartilage; it is frequent in rapidly progressive arthritis and necrosis. Several cases of synoviocytic and pseudo-tumour histiocytic hyperplasia are identified, as well as myxoid and amyloid degenerative disease of connective tissue and microcrystal formation.
