Between 1988 and 2002, 47 patients (50 hips) were treated with acetabular shell augmentation arthroplasty for recurrent idiopathic dislocation of their total hip arthroplasty. Apparent causes for dislocation such as deep infection, component malposition, or polyethylene wear were excluded. Follow-up averaged 74 months (range, 12-178 months), and clinically, 30 hips (60%) did not present a subsequent dislocation at most recent follow-up. In five hips (10%), deep infection after the augmentation procedure necessitated removal of the entire prosthesis. In our opinion, this technique cannot be recommended as it has an unacceptable failure and high infection rate.Résumé Entre 1988 et 2002, 47 patients (50 hanches) ont été traités avec un secteur additionnel pour luxation récidivante de la PTH. Les causes apparentes de luxations avec infection profonde, malposition du composant et usure du polyéthylène ont été exclues de cette étude. Le suivi moyen a été de 74 mois (de 12 à 178 mois), 60% des hanches (30 hanches) ne présentent pas de récidive de la luxation au dernier suivi. Dans 5 hanches (10%), une infection profonde est survenue, nécessitant l'ablation de la prothèse. Pour nous cette technique ne peut être recommandée car elle présente un taux d'échecs inacceptable et un taux d'infection important.

“…7,8 Numerous surgical techniques have been described for the treatment of hip instability. These include correction of a malpositioned component, 9,10 the use of a liner augmentation wedge 11,12 or angle-bore component, 13 increase in the size of the femoral head with a jumbo head [14][15][16] or bipolar hemiarthroplasty, 17 removal of impinging tissue, 18 and bony or softtissue reconstruction. [19][20][21][22] These have met with limited success.…”

We treated 34 patients with recurrent dislocation of the hip with a constrained acetabular component. Roentgen stereophotogrammetric analysis was performed to assess migration of the prosthesis. The mean clinical follow-up was 3.0 years (2.2 to 4.8) and the radiological follow-up was 2.7 years (2.0 to 4.8). At the latest review six patients had died and none was lost to follow-up. There were four acetabular revisions, three for aseptic loosening and one for deep infection. Another acetabular component was radiologically loose with progressive radiolucent lines in all Gruen zones and was awaiting revision. The overall rate of aseptic loosening was 11.8% (4 of 34). Roentgen stereophotogrammetric analysis in the non-revised components confirmed migration of up to 1.06 mm of translation and 2.32 degrees of rotation at 24 months. There was one case of dislocation and dissociation of the component in the same patient. Of the 34 patients, 33 (97.1%) had no further episodes of dislocation. The constrained acetabular component reported in our study was effective in all but one patient with instability of the hip, but the rate of aseptic loosening was higher than has been reported previously and requires further investigation.

“…Insgesamt sollte jedoch bedacht werden, dass es bei der Verwendung von Antiluxationsringen und constrained Linern aufgrund des geringeren Bewegungsumfangs und der Kopplung zwischen Pfanne und Schaft zu erhöhtem Abrieb kommen kann und ein erhöhtes primäres Lockerungsrisiko besteht [32].…”
