A cost-effective junior resident training and assessment simulator for orthopaedic surgical skills via fundamentals of orthopaedic surgery: AAOS exhibit selection.
Psychomotor testing has been recently incorporated into residency training programs not only to objectively assess a surgeon's abilities but also to address current patient-safety advocacy and medicolegal trends. The purpose of this study was to develop and test a cost-effective psychomotor training and assessment tool-The Fundamentals of Orthopaedic Surgery (FORS)-for junior-level orthopaedic surgery resident education. ⋯ The FORS simulator may serve as a valuable tool for resident education.

Randomized Controlled Trial Comparative StudyRadiostereometric analysis study of tantalum compared with titanium acetabular cups and highly cross-linked compared with conventional liners in young patients undergoing total hip replacement.
Radiostereometric analysis provides highly precise measurements of component micromotion relative to the bone that is otherwise undetectable by routine radiographs. This study compared, at a minimum of five years following surgery, the micromotion of tantalum and titanium acetabular cups and femoral head penetration in highly cross-linked polyethylene liners and conventional (ultra-high molecular weight polyethylene) liners in active patients who had undergone total hip replacement. ⋯ In this young population who had undergone total hip replacement, radiostereometric analysis showed significantly less femoral head penetration in the highly cross-linked polyethylene liners compared with that in the conventional ultra-high molecular weight polyethylene liners. Penetration rates were one order of magnitude less in highly cross-linked polyethylene liners compared with ultra-high molecular weight polyethylene liners. There was no significant difference in proximal migration between the tantalum and titanium acetabular cups through the five-year follow-up (p > 0.19).

Smaller body size increases the percentage of blood volume lost during posterior spinal arthrodesis.
Our goal was to analyze the relationship between patient size and the proportion of blood volume lost during spinal arthrodesis in patients with a diagnosis of adolescent idiopathic scoliosis, Scheuermann kyphosis, or cerebral palsy. We hypothesized that smaller patients (those with less blood volume) lose a greater proportion of circulating total blood volume during surgery. ⋯ There is an inverse relationship between the proportion of blood volume lost during deformity correction surgery and size in patients with adolescent idiopathic scoliosis, cerebral palsy, or Scheuermann kyphosis.

ReviewEstimating the global incidence of femoral fracture from road traffic collisions: a literature review.
Worldwide, road injuries cause over 1.3 million deaths and many more disabilities annually, disproportionately affecting the young and the poor. Approximately one in ten road injuries involves a femoral shaft fracture that is most effectively treated with surgery. Current femoral shaft fracture incidence according to country and age group is unknown and difficult to measure directly but is critical to designing and evaluating interventions. ⋯ Our results demonstrate a substantial worldwide burden and disparities in femoral shaft fracture incidence between low to middle income and high income countries, and the young are disproportionately affected, underscoring the potential impact of improved access to treatment. We believe that the methodology of this study can be applied to estimate the burden of other diseases, allowing for better direction of global health efforts.
