Genicular Nerve Block for Knee Osteoarthritis: A Systematic Review and Meta-analysis of Randomized Clinical Trials.

Objectives: Genicular nerve block (GNB) has emerged as a novel nonsurgical therapy for symptomatic knee osteoarthritis (KOA). The objective was to evaluate GNB versus placebo and other intra-articular (IA) therapies.

Methods: The Medline, Embase, and Scopus databases were searched from their inception to January 2021.

Three-dimensional analysis of bone site grafting on the upper extremity on computed tomography scans.

Purpose: To perform a quantitative analysis of the amount of cancellous bone in the distal radius and olecranon process by segmentation of computed tomographic scans. As a secondary analysis, the bone density by Hounsfield units was evaluated at the same sites.

Methods: Computed tomography angiography images of the upper extremity were analyzed using 3-D Slicer™ medical imaging software.

Proximal humeral fractures: association between displacement and fatty degeneration of the supraspinatus muscle.

Introduction: To evaluate the relationship between initial displacement in proximal humeral fractures and fatty degeneration of the rotator cuff measured by CT according to the Goutallier classification.

Material And Methods: This cross-sectional observational study evaluated patients with proximal humeral fractures over a six-month period. The study included patients ≥ 18 years old with complete radiological views (anteroposterior, lateral, and Grashey) and a CT scan of the affected shoulder; previous fracture or ipsilateral shoulder surgery were excluded.

Quantitative Volumetric Measurements of Bone Grafting Sites Within the Lower Extremity on Computed Tomography Scans.

The anterior iliac crest is one of the most used options; however, pain and other complications have been reported. Other options for bone harvest in the lower extremity, such as the proximal tibia and calcaneus, can be useful sites for bone grafting. Computed tomography angiography images of the lower extremity were analyzed using 3-D Slicer™ medical imaging software, creating an advanced 3-dimensional model.

Comparison of Anterior Iliac Crest Versus Proximal Tibia Autologous Bone Graft Harvesting: A Systematic Review and Meta-Analysis.

Anterior iliac crest (AIC) is the preferred option for bone grafting; however, pain and complications are reported. Proximal tibia (PT) is a sourceful site for bone grafting with lower complications. MEDLINE, EMBASE, and Scopus were searched to identify studies comparing AIC and PT autograft procedure.
