PURPOSE: In past decades, the role of sagittal alignment has been widely demonstrated in the setting of spinal conditions. As several parameters can be affected, identifying the driver of the deformity is the cornerstone of a successful treatment approach. Despite the importance of restoring sagittal alignment for optimizing outcome, this task remains challenging. Self-learning computers and optimized algorithms are of great interest in spine surgery as in that they facilitate better planning and prediction of postoperative alignment...

Introduction: Shoulder instability is one of the most common pathologies seen by the orthopedic sports medicine surgeon. With a uniquely young, high-demand patient population in the U.S. Military, the incidence of shoulder instability is remarkably more common than the civilian population. As such, military orthopedic surgeons and sports medicine and shoulder specialists have developed a unique understanding and experience of shoulder instability. The historical advances of shoulder instability in the military have been instrumental in understanding the epidemiology, evaluation, pathology, treatment of first-time shoulder subluxations and dislocations, operative and non-operative treatment options, arthroscopic and open stabilization methods, management of the in-season athlete, treatment of combined and circumferential labral pathology, and associated pathology...

Navigation in surgery has increasingly become more commonplace. The use of this technological advancement has enabled ever more complex and detailed surgery to be performed to the benefit of surgeons and patients alike. This is particularly so when applying the use of navigation within the field of orthopedic oncology. The developments in computer processing power coupled with the improvements in scanning technologies have permitted the incorporation of navigational procedures into day-to-day practice. A comprehensive search of PubMed using the search terms "navigation", "orthopaedic" and "oncology" yielded 97 results...

New 3-dimensional digital technologies are revolutionizing orthopedic clinical practice, allowing structures of any complexity to be manufactured in just hours. Such technologies can make surgery for complex cases more precise, more cost-effective, and possibly easier to perform. Applications include pre-operative planning, surgical simulation, patient-specific instrumentation and implants, bioprinting, prosthetics, and orthotics. The basic principles of 3- dimensional technologies, including imaging, design, numerical simulation, and printing, and their current applications in orthopedics are reviewed...

BACKGROUND: Multiple studies have concluded that patients are more likely to understand and trust physicians who dress in more formal attire (shirt and tie) as opposed to casual attire (t-shirts and jeans). The white coat has repeatedly been reported as a major source of trust and confidence in a patient's eyes. METHODS: This study explores the effect an orthopedic hand surgeon's attire has on a patient's perception of their surgeon's clinical values. All patients 18 years of age and older who visited our orthopedic hand surgeon's suburban outpatient practice were asked to participate in our survey-based study...

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 alignment of the acetabular cup is verified in C-arm x-ray images that are acquired in an anterior-posterior (AP) view. Favorable surgical outcome is, therefore, heavily dependent on the surgeon's experience in understanding the 3-D orientation of a hemispheric implant from 2-D AP projection images. This work proposes an easy to use intraoperative component planning system based on two C-arm x-ray images that are combined with 3-D augmented reality (AR) visualization that simplifies impactor and cup placement according to the planning by providing a real-time RGBD data overlay...

Cartilage disorders, including focal cartilage lesions, are among the most common clinical problems in orthopedic practice. Left untreated, large focal lesions may result in progression to osteoarthritis, with tremendous impact on the quality of life of affected individuals. Current management strategies have shown only a modest degree of success, while several upcoming interventions signify better outcomes in the future. Among these, stem cell therapies have been suggested as a promising new era for cartilage disorders...

Approximately 50% of cats admitted to Australian shelters are kittens, and 26% of dogs are puppies, and, particularly for cats, euthanasia rates are often high. Cats can be pregnant by 4 months of age, yet the traditional desexing age is 5-6 months, and studies in Australasia and Nth America reveal that only a minority of veterinarians routinely perform early age desexing (EAD) of cats or dogs, suggesting they are not graduating with these skills. This study aimed to describe the attitudes of veterinary teaching staff in Australian and New Zealand universities towards EAD, and to determine if these changed from 2008 to 2015...

BACKGROUND: Essential Skills in the Management of Surgical Cases (ESMSC) is an international undergraduate surgical masterclass which combines ex vivo, dry lab and high fidelity in vivo simulation-based learning (SBL). It consists of 32 stations of skills-based learning, including open reduction internal fixation (ORIF) of fractures. Current literature suggests early involvement in skills-based learning at the undergraduate level is vital. AIMS: To compare students' dexterity and skills-based performance with demographic and educational background parameters...

PURPOSE: Although they are considered the 'gold standard' of evidence-based medicine, randomized controlled trials are still a rarity in orthopedic surgery. In the management of patients with multiple trauma, there is a current trend toward 'damage control orthopedics', but to date, there is no proof of the superiority of this concept in terms of evidence-based medicine. The purpose of this article is to present unexpected difficulties we encountered in successfully completing our randomized controlled trial and to discuss the problematic differences between theoretically planning a trial and real-life practical experience of implementing the plan, with attention to published strategies...

BACKGROUND: In total knee arthroplasty (TKA), revision cases are often technically more challenging, and require more operative time and aftercare than primary cases. These time and effort differences should therefore be appropriately compensated for when using the relative value unit (RVU) system. Therefore, the purpose of this study is to compare the mean (1) RVUs; (2) operative times; and (3) RVU/min; and (4) perform an individualized idealized surgeon annual cost difference analysis for primary vs revision TKA...

BACKGROUND: Surgical resident participation in the operating room is necessary for education and progression toward safe and independent practice. However, the impact of resident involvement on patient outcomes in foot and ankle surgery is unknown. METHODS: The American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) database (2005-2012) was used to identify common foot and ankle procedures (by Current Procedural Taxonomy (CPT) code) performed by orthopedic surgeons...

BACKGROUND: Opioid addiction and overdose are epidemic in the U.S. Victims of traumatic injury are at greater than average risk for opioid misuse and related complications. Potential risk screens and preventive interventions in this clinical population remain under-investigated. The current project seeks to develop and pilot the implementation of a screening tool for opioid risk at American College of Surgeons (ACS) Level I and Level II trauma centers. METHODS: The project began with an online survey, which was sent to Wisconsin trauma center medical directors and trauma coordinators for the purpose of gathering information on current substance use screening practices...

Baseball pitching imposes significant stress on the upper extremity and can lead to injury. Many studies have attempted to predict injury through pitching mechanics, most of which have used laboratory setups that are often not practical for population-based analysis. This study sought to predict injury risk in professional baseball pitchers using a statistical model based on video analysis evaluating delivery mechanics in a large population. Career data were collected and video analysis was performed on a random sample of former and current professional pitchers...

It is well known that balance control is affected by aging, neurological and orthopedic conditions. Poor balance control during gait and postural maintenance are associated with disability, falls and increased mortality. Gait initiation - the transient period between the quiet standing posture and steady state walking - is a functional task that is classically used in the literature to investigate how the central nervous system (CNS) controls balance during a whole-body movement involving change in the base of support dimensions and center of mass progression...
