Abstract
Introduction: Recurrent Instability of the hip remains a difficult problem to treat successfully. The Posterior Lip Augmentation Device (PLAD) is a useful option where there is no gross mal-orientation of the components.
Methods: A retrospective single surgeon review was performed to identify patients who had undergone application of a PLAD to treat recurrent instability. Patients with less than 12 months follow up were excluded.
Results: 14 patients were identified with an average age of 75.5 years (Range 59 – 90 years). There were 7 cases of trochanteric non-union as a result of previous surgery. The mean follow up was 26 months (Range 13 – 41 months). In 13 patients there have been no further instances of dislocation. 1 patient went on to dislocate again and has now undergone a socket revision.
Conclusion: Application of the Posterior Lip Augmentation Device is a well tolerated procedure with very favourable success rates (93%). Given the limited morbidity and short operating time associated with this surgical option it provides a predictable outcome in cases where the original components are well orientated and securely fixed.
