The poor results of surgical treatment of chronic instability after total hip arthroplasty led to the development of a constrained acetabular component. Two constrained liners are commonly used, the Omnifit (Osteonics, Allendale, NJ) and the SROM liner (Joint Medical Products, Stamford, CT). However, dislocation may still occur if the patient cannot follow up counseling to ensure proper rehabilitation and positioning compliance. We report a 75-year-old female who sustained dislocation of the right hip two times after total hip arthroplasty with the use of a constrained acetabular component. If dislocation occurs out of a constrained liner, open reduction is indicated. Since she was a medically compromised and poor surgical candidate, open reduction was deemed unsuitable. We therefore tried close reduction and obtained a successful result/ Hence, we recommend close reduction as the first strategy for treating such a patient. |
