Introduction: To date, there is no consensus on which anterior surgical technique is more cost-effective in treating cervical degenerative disc disease (CDDD). The most commonly used surgical treatment for patients with single- or multi-level symptomatic CDDD is anterior cervical discectomy with fusion (ACDF). However, new complaints of radiculopathy and/or myelopathy commonly develop at adjacent levels, also known as clinical adjacent segment pathology (CASP). The extent to which kinematics, surgery-induced fusion, natural history, and progression of disease play a role in the development of CASP remains unclear. Anterior cervical discectomy with arthroplasty (ACDA) is another treatment option that is thought to reduce the incidence of CASP by preserving motion in the operated segment. While ACDA is often discouraged, as the implant costs are higher while the clinical outcomes are similar to ACDF, preventing CASP might be a reason for ACDA to be a more cost-effective technique in the long term.
Methods And Analysis: In this randomized controlled trial, patients will be randomized to receive ACDF or ACDA in a 1:1 ratio. Adult patients with single- or multi-level CDDD and symptoms of radiculopathy and/or myelopathy will be included. The primary outcome is cost-effectiveness and cost-utility of both techniques from a healthcare and societal perspective. Secondary objectives are the differences in clinical and radiological outcomes between the two techniques, as well as the qualitative process surrounding anterior decompression surgery. All outcomes will be measured at baseline and every 6 months until 4 years post-surgery.
Discussion: High-quality evidence regarding the cost-effectiveness of both ACDA and ACDF is lacking; to date, there are no prospective trials from a societal perspective. Considering the aging of the population and the rising healthcare costs, there is an urgent need for a solid clinical cost-effectiveness trial addressing this question.

Department of Obstetrics and Gynaecology, Monash University, Clayton, VIC, 3168, Australia.
Introduction And Hypothesis: Autologous fascia lata has been increasingly utilised in pelvic floor reconstructive surgeries such as sacrocolpopexy and sacrohysteropexy. This case highlights sacrohysteropexy with autologous fascia lata as a promising option for women with advanced uterovaginal prolapse who wish to preserve their uterus and avoid synthetic mesh.
Methods: We report the case of a 65-year-old woman with stage 3 pelvic organ prolapse following one forceps and one spontaneous vaginal delivery.

Beckman Laser Institute & Medical Clinic, University of California - Irvine, Irvine, California, U.S.A.
Objective: Repositioning and fixation of the posterior septal angle (PSA) relative to the anterior nasal spine (ANS) is a well-known maneuver performed during rhinoplasty. Suture techniques through the periosteum along with transosseous drilling through the spine are the two most common fixation methods. We report on how nasal airway patency varies as a function of technique and patient demographic factors.

Neurosurgery and Spine Departments, National Neuroscience Institution, King Fahad Medical City Riyadh, Saudi Arabia.
Background: Post-surgical recovery following spine surgeries poses challenges for Muslim patients wishing to resume Salah (Islamic prayer), which involves physical movements like kneeling and prostration. This study aims to examine spine surgeons' perspectives on the appropriate timing and conditions for resuming Salah after spine surgery without restrictions.
Methods: This cross-sectional survey study included surgeons in Saudi Arabia who perform spine surgeries.
