[Intraoperative acetabular periprotesic fracture].

Unlabelled: Intraoperative acetabular fractures (IAF) is a rare complication with an incidence 2% - 5%. We present the review of a series of 13 cases, discussing diagnosis, treatment and results.

Material And Methods: Between 2006 and 2018, we performed 4800 primary hip arthroplasties (THA) In our hospital, we identified 13 cases with FIA with a follow-up of 38.3 months.

Results: Two cases were stable with conservative management; 11 unstable cases: seven cases we placed trabecular metal, one case we increased acetabular diameter, one case acetabular replacement, one case revision with Ganz type ring and one case do not accept treatment. The use of trabecular metal is an implant that helps effectively and with good results in FIA.

Conclusion: These fractures are rare, knowing the implant to use is mandatory because if the implants are oversized, with greater rigidity or hemispheric, patients have increased risk of suffering from this complication.
