Physical work demands and posture constraint from operating microscopes may adversely affect microsurgeon health and performance. Alternative video displays were developed to reduce posture constraints. Their effects on postures, perceived efforts, and performance were compared with the microscope. Sixteen participants performed microsurgery skill tasks(More)
The purpose of this paper is to present a quantitative posture analysis of microsurgery tasks performed with different visualization methods. Microsurgery is traditionally performed using a binocular microscope; however surgeons are constrained by the optical eyepieces and are forced to assume joint angles that deviate away from neutral postures. This may(More)
PURPOSE A trend in large myelomeningocele defect repair involves soft tissue closure with muscle and fascial flap techniques to provide a durable, protective, and tension-free soft tissue covering. We propose that composite tissue closure yields superior outcomes regardless of defect size. METHODS We present a retrospective review of our 15-year,(More)
Instruction in the use of forceps and needle driver to suture tissues typically involves group didactic and demonstration sessions, followed by limited individual observation and coaching. Most motor learning required for dexterous suturing takes place during unsupervised practice with practice boards or during actual procedures in the operating room. We(More)
BACKGROUND Reviewing program educational efforts is an important component of postgraduate medical education program accreditation. The post-graduate review process has evolved over time to include centralized oversight based on accreditation standards. The institutional review process and the impact on participating faculty are topics not well described in(More)
Vascular malformations are congenital lesions secondary to errors in the development of arteries, capillaries, veins, or lymphatics. Most of these lesions are sporadic; however, a certain percentage present with syndromes. This article discusses the clinical features, natural history, and epidemiology of these lesions, and the diagnostic imaging features of(More)
Prolonged static work postures and posture constraints imposed by surgical equipment may increase the risk of musculoskeletal pain and discomfort in surgeons. Four surgeons were video recorded performing live microsurgery and a work sampling methodology was used to quantify their upper body postures, investigating the proportion of static and dynamic(More)
A taxonomy was developed a) to describe surgical procedures with sufficient detail to review differences among surgeons, b) to examine the relationship between individual technique and outcomes, c) to enable surgeons to standardize technique around best practices and d) to identify clinical-evidence-based key points of teaching and assessment for surgical(More)
This article is a review of vascular tumors and malformations that occur in infancy and childhood. It discusses anomalies of arterial, venous, capillary, lymphatic, and mixed vascular endothelium in terms of their varying forms, clinical course, imaging characteristics, complications, and treatment. The comparative utility of various imaging modalities is(More)
