Using Immersive Virtual Reality to Classify Pediatric Thoracolumbar Spine Injuries.

Objective This study aimed to assess the reliability and reproducibility of the AO Spine Thoracolumbar Injury Classification System by using virtual reality (VR). We hypothesized that VR is a highly reliable and reproducible method to classify traumatic spine injuries. Methods VR 3D models were created from CT scans of 26 pediatric patients with thoracolumbar spine injuries.

Mechanisms of lumbar spine "flattening" in adult spinal deformity: defining changes in shape that occur relative to a normative population.

Purpose: Previous work comparing ASD to a normative population demonstrated that a large proportion of lumbar lordosis is lost proximally (L1-L4). The current study expands on these findings by collectively investigating regional angles and spinal contours.

Methods: 119 asymptomatic volunteers with full-body free-standing radiographs were used to identify age-and-PI models of each Vertebra Pelvic Angle (VPA) from L5 to T10.

Robotics Coupled With Navigation for Pediatric Spine Surgery: Initial Intraoperative Experience With 162 Cases.

Background: This study assesses intraoperative efficacy, accuracy, and complications of pedicle screw placement using robotic-assisted navigation (RAN) in pediatric spine surgery.

Methods: A retrospective review of patients who underwent spine deformity surgery using RAN at a single pediatric institution from 2019 to 2021 was conducted. Patient demographics, perioperative metrics, screw execution and accuracy, technical difficulties, and other outcomes were summarized.

Use of a high-speed drill in robotics coupled with navigation for pediatric spine surgery.

With the increasing number of surgeries for pediatric spinal deformities, the aim has been to reduce the associated complications, such as those caused by screw malposition. This case series is an intra-operative experience with a new navigated high-speed revolution drill (Mazor Midas, Medtronic, Minneapolis, MN) for pediatric spinal deformity to assess accuracy and workflow. 88 patients, ranging from 2 to 29 years of age, were included who underwent posterior spinal fusion with the navigated high-speed drill.

Implementation of a Geriatrics-Focused Orthopaedic and Hospitalist Fracture Program Decreases Perioperative Complications and Improves Resource Utilization.

Objective: To evaluate whether the implementation of a geriatrics-focused orthopaedic and hospitalist comanagement program can improve perioperative outcomes and decrease resource utilization.

Design: A retrospective chart review study was conducted before and after the implementation of a geriatrics-focused orthopaedic and hospitalist comanagement program, based on the American Geriatrics Society (AGS) AGS CoCare:Ortho.

Setting: A large urban, academic tertiary center, located in the greater New York metropolitan area.

Robotic-Assisted Total Hip Arthroplasty in Patients Who Have Developmental Hip Dysplasia.

Introduction: Total hip arthroplasty (THA) in the setting of developmental dysplasia of the hip (DDH) presents more inherent complexities than routine primary THA for osteoarthritis. These include acetabular bone deficiency, limb length discrepancy (LLD), and abnormal femoral anteversion. Three-dimensional planning and robot-assisted (RA) bone preparation may simplify these complex procedures and make them more reproducible.

Completion of the Updated Caprini Risk Assessment Model (2013 Version).

The Caprini risk assessment model (RAM) has been validated in over 250 000 patients in more than 100 clinical trials worldwide. Ultimately, appropriate treatment options are dependent on precise completion of the Caprini RAM. As the numerical score increases, the clinical venous thromboembolism rate rises exponentially in every patient group where it has been properly tested.
