Outcome measurements will include objective and subjective clinical data, complications and adverse events, radiographic data measurements recorded at several postoperative intervals.', 'detailedDescription': "Hypothesis, open questions and specific aims of the project:\n\nWe believe that it is important to gain further insight in the process of bone graft remodeling and the preservation of bone stock after bone impaction grafting.\n\nRadiographs are far from conclusive and CT scan can not be repeated on regular intervals for obvious reasons. Prospective follow-up of the BMD of the bone impaction area will contribute to our further understanding. There is no literature available on BMD changes in the acetabulum after bone impaction grafting.\n\nFrom our recent experiences with earlier research on BMD in specific ROI in the femoral neck we are motivated to further explore the potential of our DEXA technology and software in the field revision hip arthroplasty.\n\nWe hypothesize that BMD changes in the bone impaction grafted acetabulum can be adequately monitored with modern DEXA techniques.\n\nResearch Questions are:\n\n1. Will bone impaction grafting of the acetabulum result in a well preserved/remodelled bone stock within 2 years after revision hip arthroplasty?\n2. Can changes in BMD be interpreted as representative for the process of bone remodelling in the bone impacted area?\n\n Study design\n\n This trial as described in this protocol is a prospective explorative follow-up study recording the clinical, radiographic data, and bone mineral density data at specific time intervals (preoperative, within 2 weeks postoperative, at 3months, 6months, 1 year and 2 years postoperative). The data will be collected using SPSS (version 20.)\n\n Main objective:\n\n To prospectively assess the BMD at short and medium time intervals in specific ROI as an indicator for the process of bone remodelling and ossification of the bone impaction graft after revision hip arthroplasty..\n\n Secondary Objectives:\n\n Clinical scores (SF-12, Oxford Hip score, VAS pain and VAS satisfaction) will be obtained. Vigilant identification of Adverse Events (AEs) will be maintained throughout the study. Mean changes in clinical scores, over time, will also be tested with repeated measurement statistics. Because clinical success is not always indicative of radiographic success and vice versa, correlations will be made.\n\n Sample size:\n\n Our study concerns an explorative study in twenty patients.\n\n Study duration:\n\n The expected duration of the study is approximately 3 years from the commencement of subject enrollment. Subject enrollment is expected to take 1 year. All subjects will be followed for at least two years after surgery until the last subject achieves two-years follow-up.\n\n Evaluation criteria\n\n The study is designed to evaluate possible clinical, radiographic and bone densitometry differences changes after revision hip arthroplasty.\n\n Evaluation criteria at different follow-up intervals.\n\n A Clinical:\n * the patient's own evaluation according to the Oxford Score, Dutch translation validated\n * the patient's evaluation of his general health with the SF-12 score , license to validated Dutch translation11\n * the patient's degree of pain and satisfaction with the prosthesis and the procedure.\n\n B Radiological:\n * X-ray evaluations of implant stability, migration, changing of cup or head angles, radiolucent lines, loosening and osteolysis. X-Rays should preferably be digital, at preoperative, 6 months, 1 year and 2 years.\n\n C. DEXA bone density measurements\n\n \\- Bone density measurements will be performed preoperative on the acetabulum on several regions of interests (ROI's) including the bone impaction grafting area. Once this ROI's of the acetabulum has been determined it can be digitalized and saved into the software, subsequently this ROI can be transported 4 days postoperative and at 4 days postoperative, 6 months, 1 year and 2 years.\n\n \\- This method has been tested in our earlier resurfacing study and has proved to be reliable and reproducable.\n\n \\- An independent radiologist will do the measurements on the DEXA-scan\n\n D Survival after revision hip arthroplasty with bone impaction grafting - According to Kaplan Meiers survival rates.\n\n E Complications and adverse events\n\n \\- Early and late complications possibly associated with revision hip arthroplasty and possible relationship with bone impaction grafting and surgical technique."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '75 Years', 'minimumAge': '35 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n1. revision hip arthroplasty with acetabular defects eligible for bone impaction grafting\n2.
