We studied four different methods of registration of dislocations after total hip arthroplasty (THA) carried out at Malmö General Hospital during 1979-1988. Established registers failed to incorporate more than half of the dislocations and approximately one third of the patients, compared with a manual retrospective review of the original operating cords and the patient files. In 22 percent of the cases the first dislocation occurred more than one year postoperatively. Therefore different studies must use similar methods of registration concerning all details about dislocations in order to allow an adequate comparison of THA dislocation parameters.
MRI is rapidly altering the presurgical evaluation for many forms of musculoskeletal pathology, and the indications for MRI will undoubtedly continue to grow. Because of the complexity of this modality and the ability to totally "miss" pathology by the inappropriate choice of imaging plane or pulse sequence, cooperation between the orthopedic surgeon and the radiologist is essential. A close working relationship is required for maximum diagnostic information to be obtained with each examination and for optimal patient care.
