Abstract
Since 1982 the bipolar hemiarthroplasty has been performed for the primary surgery of the coxarthrosis. One hundred twenty-four patients (144 hips) were available for follow-up assessment. Mean follow-up interval was 3 years 11 months (range, 1 to 8 years 4 months). The prostheses used were Bateman UPF for 49 hips and collarless, microstructured Omnif it hip system for 95 hips. Radiologically, migration of the outer head was observed 6.9% superiorly and 7.8% centrally. Subsidence of the stem was 5.5%. Omnifit prosthesis was more stable than Bateman UPF. Clinically, good-to-excellent result was obtained in 76.6%. The JOA hip rating score improved 84.7 points after surgery from the preoperative average 47.4. No deterioration of the results during follow-up intervals was observed. Pain relief was remarkable and consequently it influenced on improvement of gait ability and ADL.The intermediate follow-up study suggests a role for the bipolar hemiarthroplasty in the primary surgical treatment of coxarthrosis.
