Occult intra-operative periprosthetic acetabular fracture is a seldom-reported complication of primary total hip arthroplasty (THA). It may potentially be associated with cup instability and implant loosening. The present study aimed to investigate clinical consequences of this complication. ⋯ Central wall acetabular fractures, although unrecognized intra- and post-operatively may impair implant survival after THA.
