Constrained Liners for Recurrent Dislocations in Total Hip Arthroplasty
Knudsen R, Ovesen O, Kjaersgaard-Andersen P, Overgaard S.Hip
This study reports the results and complications from treating recurrent hip dislocations with a constrained liner (CL) after total hip arthroplasty (THA).
Forty patients who had a CL inserted as a secondary prophylactic treatment were retrospectively reviewed after a median observation period of 27 months (range 7–77 months).
During the observation period five patients had to be revised: one for deep infection and four on account of re-dislocations.
Our results indicate that patients with recurrent THA dislocations can be treated with a CL and has a satisfactory low complication rate and a relatively low risk of re-dislocation.
