[Long term results after total hip replacement--cemented and cementless in young rheumatic patients]

T.H.R in young adults or in youth is still doubtful in the aspect of late results and inevitability of revisions. Rheumatic patients are a specific group due to character of the disease, multiorgan complications and side effects of pharmacological treatment. Aim of the study was to evaluate the late results and to compare cemented and cementless T.H.R.

between 1980-1990 122 T.H.R (70 cementless and 52 cemented) on 80 rheumatic patients of age from 18 do 42 (average 28.5) were performed in our clinic. The follow-up was from 14 to 24 years. Clinical and radiographic examinations were done on 28 patients (35%) with 21 cementless and 21 cemented prostheses. 16 patients had bilateral T.H.R., 8 patients died. The results were evaluated using Merle d'Aubigne hip score and by own opinion of patients. There were 7 revisions due to aspetic loosening in cementless (in 2 cases only acetabular components) and 6 in cemented prostheses. There were no superficial or deep infections. Obtained results indicated that survivorship of prostheses was rather long. It was probably due to limited general mobility caused by pathologic changes in other joints of lower limbs and using aids during walking. The results after cemented and cementless prostheses were similar. Adjournment of operation in young rheumatoid patients is useless because in the later stage of the disease is more difficult.
