Dislocation and instability complicating low friction arthroplasty of the hip joint
Insights
Total hip arthroplasty dislocations can occur, often due to technical faults or prior surgeries. Careful adherence to the Charnley procedure, including soft tissue management, is crucial for preventing hip instability and dislocation.

Abstract:
Among the complications in a series of 1,400 consecutive Charnley low friction arthroplasty procedures, there were 8 dislocations, and 3 highly unstable hips. Three dislocations followed severe trauma, in 2 of the 3 there was only fibrous union of the greater trochanter. In all but 2 of the hips, more than one previous operation had been performed. More than one technical fault was evident in most dislocations. Six of the 8 dislocations required reoperation. Meticulous attention to the Charnley procedure, including soft tissue elements of the hip joint is necessary to avoid instability and dislocation following total hip arthroplasty.
