Socket wall addition device in the treatment of recurrent hip prosthesis dislocation: good outcome in 12 patients followed for 4.5 (1-9) years.
BACKGROUND
Recurrent dislocation in total hip replacement is difficult to treat and causes severe morbidity.


METHODS
12 patients suffering dislocations were reoperated with a socket wall addition device (anti-luxation ring) for the Lubinus SPII prosthesis, and were followed up after a mean of 4.5 (1-9) years with regard to redislocation, function and radiographic loosening.


RESULTS
1 of the patients suffered a redislocation after almost 7 years of use. There was no loosening during the follow-up time. A Harris hip score of 87 (60-100), a health-related quality of life (EQ-5D) index of 0.8 (0.6-1.0) and total range of motion of 145 degrees (125-165) indicate that the patients had a level of function comparable to that of age-matched hip surgery patients with no complications.


CONCLUSIONS
The anti-luxation ring shows promising mid-term results and seems to provide an alternative to more extensive revision surgery for selected patients.
