Cemented Total Hip Arthroplasty With Retrograde Ischioacetabular Steinmann Pin Reconstruction for Periacetabular Metastatic Carcinoma.

Background: Surgical management of advanced periacetabular lesions is challenging because of extensive bone loss, particularly for Modified American Academy of Orthopaedic Surgeons Classification defects type IV (pelvic discontinuity with posterior column involvement). Multiple methods for rebuilding the acetabulum have been described; all involve passing Steinmann pins in a retrograde or an antegrade fashion from the anterior iliac wing or iliac crest around the acetabulum in an attempt to recreate the normal bony anatomy. However, these techniques fail to engage the ischium in its entirety.

Comparison of Intrawound Vancomycin Utility in Posterior Instrumented Spine Surgeries Between Patients With Tumor and Nontumor Patients.

Study Design: Retrospective cohort study of consecutive patients.

Objective: To compare the efficacy of intrawound vancomycin to prevent postoperative surgical site infection (SSI) between patients with spinal tumor and nontumor spine patients.

Summary Of Background Data: Recent studies have suggested that intrawound vancomycin is a promising method for reducing the SSI rate in spine surgery.
