Revision THA for Neck-Taper Corrosion Results
Adverse local tissue reactions (ALTR) around a modular neck stem at our institution lead to a 13.5% rate of revision. The purpose of the study was to report the clinical results of revision total hip arthroplasty (THA) in this patient population.

80 hips in 77 patients who underwent revision THA due to neck-stem corrosion are identified. Intraoperative and postoperative complications, clinical outcomes, re-revision rates and the postoperative ion levels were recorded.

The mean follow-up period after revision was range 24-81 months. There were no intraoperative mechanical complications during the revision surgery. Eight hips (10%) had postoperative complications related to the revision implant, of which 6/8 came to re-revision: postoperative implant dislocation in 4 hips – 2 treated non-surgically, aseptic loosening of femoral component in 2 hips, and periprosthetic femoral fracture in 2 hips. No patients had recurrence of ALTR nor the recurrence of groin pain within the follow-up period.

In conclusion, intraoperative complication, postoperative complication and re-revision rates are equivalent to femoral revision surgeries for other causes (infection, fracture, loosening). Selecting revision-type stems to minimize the risk of femoral loosening or periprosthetic fracture, and larger femoral heads or dual mobility bearings to minimize the risk of dislocation is recommended.
