Background: Musculotendinous retraction is a limiting factor for repair of long-standing rotator cuff tears. However, it currently unknown to what extent the muscle and tendon contribute degree total retraction. Further understanding this may possibly influence strategy musculotendinous reconstruction. Purpose: To analyze contribution process myotendinous Study Design: Cross-sectional study; Level evidence, 3. Methods: Magnetic resonance imaging 130 shoulders with intact (n = 20) or...
Background: Limited information exists on the clinical use of a synthetic osteochondral scaffold plug for cartilage restoration in knee. Purpose/Hypothesis: The purpose this study was to compare early magnetic resonance imaging (MRI) appearance, including quantitative T2 values, between defects treated with versus platelet-rich plasma (PRP) or bone marrow aspirate concentrate (BMAC). hypothesis that addition PRP BMAC would result an improved appearance. Study Design: Cohort study; Level...
The aim of this study was to compare the degree artifact reduction in magnetic resonance imaging achieved with slice encoding for metal correction (SEMAC) combination view angle tilting (VAT) and multiacquisition variable image (MAVRIC) standard contrast weightings different metallic materials.Four identically shaped rods made most commonly used prosthetic materials (stainless steel, SS; titanium, Ti; cobalt-chromium-molybdenum, CoCr; oxidized zirconium, oxZi) were scanned at 3 T. In...
Abstract Background Ultrasound (US) images are currently displayed on monitors, and their understanding needs good orientation skills. Direct overlay of US onto the according anatomy is possible with augmented reality (AR) technologies. Our purpose was to explore performance US-guided needle placement without AR in situ viewing. Methods Three untrained operators two experienced radiologists performed 200 punctures: 100 US. The punctures were different phantoms, a leg phantom soft tissue...
AR based navigation of spine surgeries may not only provide accurate surgical execution but also operator independency by compensating for potential skill deficits. "Direct" AR-navigation, namely superposing trajectories on anatomy directly, have been investigated regarding their accuracy and operator's dependence.Purpose this study was to prove independent reliability both assisted pedicle screw rod bending in a cadaver setting.Two experienced surgeons two biomedical engineers (laymen)...
Background: Injuries to the physis are common in children with a subset resulting an osseous bar and potential growth disturbance. Magnetic resonance imaging allows for detailed assessment of ability generate 3-dimensional physeal models from volumetric data. The purpose this study was assess interrater reliability area measurements generated using validated semiautomated segmentation technique highlight clinical utility quantitative (3D) mapping pediatric orthopaedic practice. Methods:...
Abstract Objectives Augmented reality (AR), which entails overlay of in situ images onto the anatomy, may be a promising technique for assisting image-guided interventions. The purpose this study was to investigate and compare learning experience performance untrained operators puncture soft tissue lesions, when using AR ultrasound (AR US) compared with standard US (sUS). Methods Forty-four medical students (28 women, 16 men) who had completed basic course, but no US, were asked perform...
To report outcomes of a cohort with displaced femoral neck fractures (FNFs) treated length/angle-stable construct augmented an endosteal fibular allograft serving as biologic dowel.Prospective.Level I Trauma Center.The study group consists 27 patients isolated FNF surgically by single surgeon.Open reduction the neck, fixed length- and angle-stable 2 fully threaded cannulated screws dowel.Clinical radiographic fixation viability both head allograft, host response to osseous union were...
The purpose of this study was to devise a simple but reliable radiological method identifying lumbosacral transitional vertebra (LSTV) with solid bony bridge on sagittal MRI, which could then be applied lateral radiograph. vertical mid-vertebral angle (VMVA) and the anterior vertebral (VAVA) three most caudal segments lumbar spine were measured MRI and/or radiograph in 92 patients LSTV 94 controls, differences per segment (Diff-VMVA Diff-VAVA) calculated. Diff-VMVA two vertebrae...
