title: [Mecring threaded cup in total arthroplasty of the hip with acetabular protrusion].
abstract: Results of total arthroplasty of the hip with acetabular protrusion with the use of Mecring cup in 21 patients (25 hips) aged 25-75 years (mean 62) are reported. Morsalised impacted autografts were used to fill acetabular defect in all cases. There were 14 rheumatoid arthritis patients, 4 cases of osteoarthritis and 3 cases of Otto-Chrobak disease. Mean follow-up was 2.5 years (range 6 months-5 years). All autografts were incorporated after 6-9 months. Only one loosening and migration of the cup occurred. One patient died because of pulmonary embolism. Harris Hip Score increased from 37 points (22-49) preoperatively to 81 points (65-89) at the latest follow-up. Incorporation of autografts reinforced acetabular bottom and prevented recurrence of protrusion. Bone remodeling indicates restoring normal biomechanics of the hip.
