case_images: A 56-year-old patient had a complex primary THA following failure of fixation of an intertrochanteric fracture treated with a Gamma nail, 7 years ago (Figure 1).
case_images: A and B: Complex primary THA.

case_images: CoCr 36 + 10 femoral head was used and was found to be stable (Figure 2A and B). Clinical and radiographical follow up of his THA was unremarkable for 5 years postoperatively.
case_images: A and B: Proximal migration of the femoral head and radiolucent ring suggestive of polyethylene liner dissociation.

case_images: Careful evaluation of the radiographs showed that this radiolucency was consistent with a PLD (Figure 3A and B).

case_images: Trial reduction and range of movement testing were satisfactory, and hence the definitive components implanted included a Zimmer Continuum shell of size 64 mm with an offset liner and 36 mm + 12 Oxinium femoral head (Figure 5).

case_images: The polyethylene was revised and a constrained liner was used instead with a new size of 36 mm + 12 Oxinium femoral head (Figure 6A and B).
