Can Constraint Ring Fracture Without Instability Indicate Insert Failure in the Constraint Acetabular Cap Application due to Recurrent İnstability? A Case Report

Constrained acetabular liners were developed in the present study as a solution to recurrent hip instability in total hip replacement. Although it is especially preferred in patients with cognitive disorders, it is associated with issues such as ring problems and complications related to the acetabular component. In this study, a patient with intellectual disability and constrained ring fracture was presented. During the follow-up stage of the study, it was observed that the insert was fractured.
