IMPLANTATION OF A CEMENTED TOTAL ENDOPROS THESIS IN ONE OPERATION BY A BILATERAL FEMORAL-NECK FRACTURE WITH OSTEOGENESIS IMPERFECTA TARDA

Osteogenesis imperfecta tarda is a hereditary disease with an insuffic iency of osteoblasts caused by a collagen disorder, insufficient forma tion of osteoid and an impediment of periosteal bone formation. This l eads to increased fragility of the bones and, as a consequence, to the risk of fractures. We report a simultaneous, bilateral medial femoral neck fracture, caused by a cerebral cramp attack. The patient is 80 y ears old and suffers from osteogenesis imperfecta tarda and Parkinson' s disease. We implanted a cemented total endoprosthesis on each side i n just one operation. There were no complications in the intra- and po stoperative course. A walking aid gradually increased the patient's mo bility so that he could be discharged on the 21st postoperative day.
