Is The Dislocation of Hemiarthroplasty Resolved?

Keywords: Hemiarthroplasty, dislocation, reduction, recurrence

Abstract

Introduction: The hip hemiarthroplasty dislocation is a challenging complication due to patient frailty, associated comorbidities, poor bone and soft tissue quality. Materials and Methods: We have studied 28 cases of dislocation after hemiarthroplasty and compared with 56 control patients with one year follow-up. Closed reduction under general anesthesia were made in 26 cases. The study analyzed recurrence episodes of dislocation, considering various factors influencing instability recurrence. Results: Among the 28 patients with dislocation post-hemiarthroplasty, there was an overall mortality 42% within the first 12 months, compared to 21% in the group of patients who did not experience a dislocation episode (p<0.001.) Recurrence following the initial reduction occurred in 12 cases (42%). Cases resulting from trauma had a lower recurrence risk than those occurring spontaneously or with minor with a OR of 11. Similarly, dislocations in patients with moderate to severe cognitive decline had a higher recurrence riskcompared to those without cognitive decline, with an OR of 5.5 Conclusions: Hemiarthroplasty dislocation is associated with a significantly increased mortality rate. While closed reduction under general anesthesia is often considered the preferred management, it is associated with a high failure rate, especially in patients with moderate to severe cognitive decline or with spontaneousdislocations.
