Two-stage revision with the removal of all prosthesis has been considered to be the gold standard for treatment of periprosthetic joint infection. However, removal of well-fixed femoral stem is technically challenging and may cause excessive bone loss. The aim of this study was to compare the results between retention and removal of femoral stem when performing two-stage revision total hip arthroplasty for periprosthetic joint infection. From 2007 to 2014, ninety-four patients with infection after hip arthroplasty were treated by using two-stage exchange protocol with temporary articulating spacers. Among them, 38 patients completed the planned second stage reimplantation. Stem was exchanged in 15 patients (group I) and retained in 23 patients (group II). We retrospectively investigated the clinical and radiographic results after an average 39.9 months follow upPurpose
Materials & Methods
Thermal injury to the radial nerve caused by cement leakage is a rare complication after revision elbow arthroplasty. Several reports have described nerve palsy caused by cement leakage after hip arthroplasty. However, little information is available regarding whether radial nerve injury due to cement leakage after humeral stem revision will recover. In a recent study, radial nerve palsy occurred in 2 of 7 patients who had thermal injury from leaked cement during humeral component revisions. These patients did not regain function of the radial nerve after observation. We present a case of functional recovery from a radial nerve palsy caused by cement leakage after immediate nerve decompression in revision elbow arthroplasty[Fig. 1.2].
