Does pelvic tilt change with a peri-acetabular osteotomy?

Change in pelvic tilt (PT) during and after peri-acetabular osteotomy (PAO) is important for surgical planning. The aims of this study were to (i) determine how PT varies throughout the course of treatment in patients undergoing PAO, (ii) test what factors influence the change in PT and (iii) assess whether changes in PT influenced achieved correction. This is an retrospective, single-centre, consecutive case series of 111 patients treated with PAO for global ( = 79), posterior ( = 49) or anterior dysplasia ( = 6) (mean age: 27.

Spinal Anesthesia for Primary Hip and Knee Arthroplasty: Comparative Rates of Transient Neurological Symptoms and Urinary Retention Using Lidocaine, Mepivacaine, and Bupivacaine.

Background: Short-acting spinal anesthetics enable rapid recovery after hip and knee arthroplasty; however, concerns with transient neurological symptoms (TNS) cause some to avoid using lidocaine. Postoperative urinary retention (POUR) is also a concern with spinal anesthesia. We sought to study the comparative rates of TNS and POUR between lidocaine, mepivacaine, and bupivacaine in a high-volume hip and knee arthroplasty setting.

Low dose vancomycin-loaded spacers for two-stage revision knee arthroplasty: High success, low toxicity.

Background: Two-stage revision arthroplasty is a widely used treatment method for infected knee arthroplasty. Loading high doses of antibiotics to spacer during the first stage is standard practice. However, there are reported systemic side effects attributed to antibiotic-loaded spacers.

Do modic changes, disc degeneration, translation and angular motion affect facet osteoarthritis of the lumbar spine.

The objective of the study is to identified the correlation between Modic changes (MCs), disc degeneration, motions (translation and angulation) and facet osteoarthritis in lumbar spine. 425 patients who underwent multi-positional lumbar MRI were reviewed. A total of 2250 lumbar spinal segments in neutral position were evaluated for MCs, disc degeneration grading, translation and angulation motion, and facet osteoarthritis.

Effect of mental health on postoperative infection rates following cervical spine fusion procedures.

Purpose: The aim of this study was to determine whether having an existing psychiatric disorder is a risk factor for developing post-operative infection following anterior cervical discectomy with fusion (ACDF) and posterior cervical fusion (PCF).

Results: A total of 34,007 patients within Humana database was included in this study. Patients with mental disorders had post-operative infection rates of 3.
