[The use of Müller acetabular rings in revision surgery of total hip prosthesis. Apropos of 141 cases with a minimal 5-year follow-up].

211 acetabular reinforcement rings of Müller have been implanted when revising total hip arthroplasties, 141 were followed up for more than 5 years. In 52 per cent of cases, an acetabular reconstruction using bone grafts was associated: in 51 cases, a bank allograft was used, one third of the grafts had only a role of filling. Theses rings remained remarkably stable and there were only 2 lacks of fixation: 1.4 per cent in cases non grafted. They allowed a quick weight bearing while warranting stabilisation and protection of the grafts and recentering the hip. So their use has become systematic in THR revisions except for stage IV acetabular loosenings in which the osteosynthesis of the acetabular transverse fracture can be preferred.

[An estimate of the intramural costs of the placement of a total hip prosthesis].

OBJECTIVE: Determining the intramural costs of the (re) placement of a total hip prostheses. DESIGN: Retrospective, descriptive. SETTING: Utrecht University Hospital (AZU) and the De Weezenlanden Hospital in Zwolle (ZWZ), the Netherlands. PATIENTS AND METHOD: From the records of 137 patients in whom an uncomplicated primary placement or revision of 151 total hip prostheses had taken place in the AZU or the ZWZ during the period 1990-93, data were collected on the number of days hospitalised, the length of the operation, the medical materials used, the number of radiological procedures, ECG's and laboratory determinations, and the visits to the outpatient clinic. The costs of a hip replacement were determined on the basis of the salary costs, tariffs and purchase prices. RESULTS: The average total cost was f 9381 for the placement of a cemented prosthesis, f 10,796 for the placement of a cement-free prosthesis, and f 17,879 for a revision operation. About 90% of the total costs were due to the price of hospitalization, surgery and prosthesis. With 14,000 primary placements and 1400 revisions annually, the cost is approximately 186 million guilders. An expected increase in the number of hip replacements and their cost should be taken into consideration.

[Luxation of hip prosthesis].

BACKGROUND: Our aim was to elucidate the dislocation rate after total hip arthroplasty at Haugesund County Hospital, Norway. MATERIAL AND METHODS: Information was obtained from the Norwegian Arthroplasty Register and from hospital patient files. All 1,076 patients (781 female) operated at the hospital 1987-2000 were included. The ITH prosthesis was used in 545 patients and the Charnley prosthesis with a smaller head in 531 patients. RESULTS: 21 patients (2.0%) experienced dislocation after total hip arthroplasty, 17 during activities of daily living and three after a fall. 17 dislocations happened within six months postoperatively. The dislocation risk was smaller for women than for men (1.3% vs 3.7%, p = 0.01). Patients with a Charnley prosthesis had a greater risk for recurrent luxations than those with a ITH prosthesis (1.7% vs 0.2%, p = 0.01). INTERPRETATION: The rate of dislocation after total hip arthroplasty in this study is similar to that of other reports in the literature.

[Rare indication for a simple hip prosthesis with an extra-large femoral head following multiple failed exchange operations].

In certain rare cases of failure following multiple exchange arthroplasty at the hip, it is possible to create a strong and reliable connection between the pelvis and the femur, without replacing the acetabulum, by fitting a custom-made extra-large femoral head into the existing and stable large cavity. Two cases in which this method was used are described here and recommended for consideration in similar situations.

[Is the high hip center a solution for revision operation in acetabulum loosening of the hip prosthesis?].

In each of 20 anatomical specimens with an acetabular defect (Paprosky type 3b) we implanted an acetabular component in the position of a high hip center. We evaluated the interface area and the migration of the hip center in relation to the normal physiological hip rotation center. The interface area showed a wide interindividual range between 1049 mm2 and 527 mm2. This represented a percentage coverage of the hip component by between 44% and 22%, with an average of 31%. The vertical migration ranged between 13 mm and 35 mm, with a consecutive lateralization in all specimens. This lateral migration ranged from 10 mm to 30 mm. Besides this, there was also significant migration in the sagittal plane, with anterior migration by between 5 mm and 25 mm. On the basis of our findings, we do not recommended the implantation of an acetabular component in the position of a high hip center.
