Acetabular Liner Dissociation following Total Hip Arthroplasty: A Rare but Serious Complication That May Be Easily Misinterpreted in the Emergency Department.

O'Neill CK, Napier RJ, Diamond OJ, O'Brien S, Beverland DE - Case Rep Emerg Med (2015)

Bottom Line: Acetabular liner dissociation is a rare complication of Total Hip Arthroplasty (THA) which requires urgent revision surgery.A case is presented in which the correct diagnosis was not appreciated on two separate Emergency Department attendances.The typical symptoms, signs, and radiological features are outlined and the importance of considering a rare complication following a commonly performed procedure is highlighted.

fig3: (a) Normal THA implant appearance. The polyethylene liner is well seated within the acetabular shell. (b) Acetabular liner dissociation appearance. The polyethylene liner has clearly migrated from its original position in (a).

Mentions: The modern uncemented acetabular component is modular in design and consists of a metal shell which accepts a polyethylene or ceramic liner following insertion intraoperatively. Liner dissociation occurs due to failure of the locking mechanism between the metal shell and liner (Figure 3). It appears to be more commonly associated with polyethylene liners due to a difference in ceramic liner locking mechanism design [5, 6].
