A total of 30% (14 of 47) of our patients experienced one or more mechanical complications. A single dislocation (Henderson type I) occurred in six patients (13%); four patients had recurrent dislocations (9%; one of whom sustained a rst dislocation after resection of an extensive recurrence). The rst dislocation occurred after a median of 20 days (range, one day to 2.6 months). Patients with a single dislocation were managed with open (n = 3) or closed (n = 3) reduction. Two patients with recurrent dislocations underwent revision to a dual-mobility cup with good results; no further dislocations occurred. Others were managed
