Robot-Assisted Reduction of the Ankle Joint via Multi-Body 3D-2D Image Registration.

Purpose: Robot-assisted orthopaedic joint reduction offers enhanced precision and control across multiple axes of motion, enabling precise realignment according to predefined plans. However, the high levels of forces encountered may induce unintended anatomical motion and flex mechanical components. To address this, this work presents an approach that uses 2D fluoroscopic imaging to verify and readjust the 3D reduction path by tracking deviations from the planned trajectory.

Healthcare workers' perspectives on trauma and mental health access for Rohingya refugees in Cox's Bazar.

Background: In August 2017, the Rohingya population of northern Rakhine State in Myanmar fled to Bangladesh following "clearance operations" by the Myanmar security forces that were characterized by widespread and systematic violence, constituting severe human rights violations. The "clearance operations" were preceded by years of consistent denial of the human rights of the Rohingya people in Myanmar. This study examines the impact of these human rights violations on the trauma experiences of Rohingya survivors, their resulting mental health, and the availability and access to post-migration mental health services.

Influence of the functional status of the anterior cruciate ligament on the posterior medial femoral condyle among varus osteoarthritic knees.

Background: Morphologic changes in the posterior medial femoral condyle (PMFC) among varus osteoarthritic knees have not been described in the past. The aims of this study were to compare anterior cruciate ligament (ACL) competent and deficient varus osteoarthritic knees during computer-navigation assisted (CAS) total knee arthroplasty (TKA) in terms of their pre-operative deformity, rotation of the posterior condylar axis (PCA) with respect to Whiteside's axis, and prevalence of PMFC hyperplasia or attrition.

Methods: Data pertaining to pre-operative varus deformity, rotation of the PCA with respect to Whiteside's axis, and presence of PMFC hyperplasia or attrition were analyzed for 250 consecutive patients each, with ACL-competent and deficient knees, who underwent CAS TKA for varus osteoarthritis of the knee.

Risk of Blindness From Temple Filler Injections: Investigating Vascular Anastomoses Between the Deep Temporal and Ophthalmic Arteries.

Purpose: Soft-tissue filler injections, particularly hyaluronic acid, are popular for temple volume restoration. Although uncommon, this area poses risk for vision loss from embolic occlusion. Guidelines recommend injecting into the supraperiosteal plane for safety; however, the deep temporal arteries (DTAs) in this plane pose a risk.
