Focal selective dorsal rhizotomy and concurrent deformity correction: a combined approach.

Objective: Selective dorsal rhizotomy (SDR) is a neurosurgical procedure to reduce spasticity in children with cerebral palsy and spastic diplegia. The authors developed a procedure called focal SDR for children with spasticity predominantly in the L5 or S1 motor distribution, which can be combined with orthopedic correction of fixed soft-tissue or bony deformity. The authors describe in detail the technique of minimally invasive focal SDR and propose selection criteria.

Tibial derotational osteotomy for idiopathic tibial torsion: A systematic review of surgical indications based on clinical presentation and measurement technique.

Purpose: The aim of this systematic review was to identify the surgical indications of tibial derotational osteotomy (TDO) in patients with idiopathic external tibial torsion (ETT) and identify common measurement thresholds for surgical correction.

Methods: A systematic search of MEDLINE and Embase via Ovid, Cochrane Library via Wiley, Web of Science, Scopus, SPORTDiscus via EBSCOhost, ClinicalTrials.gov, WHO ICTRP and Global Index Medicus databases was performed with search terms reflecting the concepts of idiopathic tibial torsion, TDOs, and surgical indications.

A Telemedicine Solution to Minimize Unnecessary Emergency Department Transfers for Low-acuity Pediatric Orthopaedic Patients: A Model for Cost Minimization.

Introduction: Unnecessary emergency department (ED) transfers represent a notable source of excess costs and misutilization of healthcare resources, particularly with management of acute pediatric musculoskeletal injuries. This study used institutional data to create a model investigating the expected costs of a formal peer-to-peer telemedicine intervention designed to triage pediatric orthopaedic transfers, which we hypothesized would decrease healthcare costs by minimizing unwarranted ED-to-ED transfers.

Methods: In this retrospective modeling analysis, 350 pediatric orthopaedic trauma patients transferred to two in-network referral hospitals from outside facilities were identified and stratified into three groups representing how patients theoretically optimally could have been treated.

Sliding Hip Screw and Side Plate for Intertrochanteric Hip Fractures.

Unlabelled: For stable intertrochanteric hip fractures, treatment commonly involves the use of a sliding hip screw. Intertrochanteric hip fractures are increasingly common as the population ages and lives longer. More than 250,000 hip fractures occur per year in the United States.

Biomechanical evaluation of sacroiliac joint fixation with decortication.

Background Context: Fusion typically consists of joint preparation, grafting, and rigid fixation. Fusion has been successfully used to treat symptomatic disruptions of the sacroiliac joint (SIJ) and degenerative sacroiliitis using purpose-specific, threaded implants. The biomechanical performance of these systems is important but has not been studied.

The utility of ultrasound for diagnosing purulent infections of the upper extremity.

Background: The purpose of this study was to determine the test characteristics of formal ultrasound when used to diagnose upper extremity soft tissue abscess in the setting of suspected infection.

Methods: We completed a retrospective chart review of all patients who had formal ultrasounds at our institution for the indication of diagnosing upper extremity abscess between July 2010 and July 2013. Using presence of purulence as the gold standard for diagnosis of abscess, we calculated the test characteristics of ultrasound.

Biomechanical diversity despite mechanobiological stability in tissue engineered vascular grafts two years post-implantation.

Recent advances in vascular tissue engineering have enabled a paradigm shift from ensuring short-term graft survival to focusing on long-term stability and growth potential. We present the first experimental-computational study of a tissue-engineered vascular graft (TEVG) effectively over the full lifespan of the recipient. We show that grafts implanted within the venous circulation of mice remained patent over 2 years without thrombus, stenosis, or aneurysmal dilatation.
