Students in undergraduate premedical anatomy courses may experience suboptimal and superficial learning experiences due to large class sizes, passive lecture styles, difficult‐to‐master concepts. This study introduces an innovative, hands‐on activity for human musculoskeletal system education with the aim of improving students’ level engagement knowledge retention. In this study, a collaborative intervention using REFLECT (augmented reality clinical anatomy) is presented. The uses augmented...
Despite the widespread use of systemic antibiotics to prevent infections in surgically treated patients with fracture, high rates surgical site infection persist.To examine effect intrawound vancomycin powder reducing deep infections.This open-label randomized clinical trial enrolled adult an operatively tibial plateau or pilon fracture who met criteria for a risk from January 1, 2015, through June 30, 2017, 12 months follow-up (final assessments completed April 2018) at 36 US trauma...
The treatment of some pelvic injuries has evolved recently to include the use a subcutaneous anterior fixator (INFIX). We present 8 cases femoral nerve palsy in 6 patients after application an INFIX highlight this potentially devastating complication surgeons using technique and discuss how it might be avoided future.Retrospective chart review. Case series.Five level 1 2 trauma centers, tertiary referral hospitals.Six with ring injury treated who experienced palsies (2 bilateral).Removal...
Fluoroscopic x-ray guidance is a cornerstone for percutaneous orthopedic surgical procedures. However, two-dimensional (2-D) observations of the three-dimensional (3-D) anatomy suffer from effects projective simplification. Consequently, many images various orientations need to be acquired surgeon accurately assess spatial relations between patient's and tools. We present an on-the-fly support system that provides using augmented reality can used in quasiunprepared operating rooms. The...
<h3>Importance</h3> Distal radius fractures (DRFs) are common injuries among older adults and can result in substantial disability. Current evidence regarding long-term outcomes is scarce. <h3>Objective</h3> To compare across treatment groups at 24 months with DRFs who participated the WRIST trial. <h3>Design, Setting, Participants</h3> The Wrist Radius Injury Surgical Trial (WRIST) randomized, international, multicenter trial was conducted from April 1, 2012, through December 31, 2016....
Reproducibly achieving proper implant alignment is a critical step in total hip arthroplasty procedures that has been shown to substantially affect patient outcome. In current practice, correct of the acetabular cup verified C-arm x-ray images are acquired an anterior–posterior (AP) view. Favorable surgical outcome is, therefore, heavily dependent on surgeon’s experience understanding 3-D orientation hemispheric from 2-D AP projection images. This work proposes easy use intraoperative...
Percutaneous screw fixation in pelvic trauma surgery is a challenging procedure that often requires long fluoroscopic exposure times and trial-and-error insertion attempts along narrow bone corridors of the pelvis. We report method to automatically plan surgical trajectories using preoperative CT assist device placement by augmenting scene with planned trajectories. A shape atlas was formed from 40 images used construct statistical model (SSM). Each member included expert definition...
Orthopaedic surgeons are still following the decades old workflow of using dozens two-dimensional fluoroscopic images to drill through complex 3D structures, e.g. pelvis. This Letter presents a mixed reality support system, which incorporates multi-modal data fusion and model-based surgical tool tracking for creating environment supporting screw placement in orthopaedic surgery. A red-green-blue-depth camera is rigidly attached mobile C-arm calibrated cone-beam computed tomography (CBCT)...
The comparison of mortality and morbidity between distal femur (DF) hip fracture in the old age is rarely reported literature. We aim to analyze a nationwide database among elderly compare outcomes fractures United States.A retrospective analysis National Trauma Data Bank was queried 2007-2014 identify patients greater than 65 years age. Outcomes analyzed included in-hospital mortality, total hospital length stay(LOS), intensive care unit stay(ICU-LOS), ventilation use discharge disposition....
Automated X-ray image segmentation would accelerate research and development in diagnostic interventional precision medicine. Prior efforts have contributed task-specific models capable of solving specific analysis problems, but the utility these is restricted to their particular task domain, expanding broader use requires additional data, labels, retraining efforts. Recently, foundation (FMs) -- machine learning trained on large amounts highly variable data thus enabling broad applicability...
Spinal screw placement is a challenging task due to small bone corridors and high risk of neurological or vascular complications, benefiting from precision guidance/navigation quality assurance (QA). Implicit both guidance QA the definition surgical plan-i.e. desired trajectories device selection for target vertebrae-conventionally requiring time-consuming manual annotations by skilled surgeon. We propose automation such planning deriving pedicle trajectory patient's preoperative CT MRI. An...
Intraoperative x-ray radiography/fluoroscopy is commonly used to assess the placement of surgical devices in operating room (e.g. spine pedicle screws), but qualitative interpretation can fail reliably detect suboptimal delivery and/or breach adjacent critical structures. We present a 3D-2D image registration method wherein intraoperative radiographs are leveraged combination with prior knowledge patient and components for quantitative assessment device more rigorous quality assurance (QA)...
Interventional C-arm imaging is crucial to percutaneous orthopedic procedures as it enables the surgeon monitor progress of surgery on anatomy level. Minimally invasive interventions require repeated acquisition X-ray images from different anatomical views verify tool placement. Achieving and reproducing these often comes at cost increased surgical time radiation. We propose a marker-free 'technician-in-the-loop' Augmented Reality (AR) solution for repositioning. The technician operating...
