Exposure to ionizing radiation in the operating room is governed by practical prevention and protection measures on the international, national and local levels. We evaluated the equivalent dose to the hand of an orthopedic surgeon over 13 months. An orthopedic surgeon wore a ring dosimeter on the ring finger of his right hand for all surgical procedures requiring intraoperative fluoroscopy between March 2014 and April 2015. Monthly doses were evaluated by the IRSN over the study period. The number and type of procedures were compiled as well as the type of fluoroscopy unit used...

PURPOSE: Pyogenic spondylodiscitis (PS) is still burdened by a high rate of orthopedic and neurological complications. Despite the rising incidence, the choice of a proper orthopedic treatment is often delayed by the lack of clinical data. The aim of this study was to propose a clinical-radiological classification of pyogenic spondylodiscitis to define a standard treatment algorithm. METHODS: Based on data from 250 patients treated from 2008 to 2015, a clinical-radiological classification of pyogenic spondylodiscitis was developed...

Objective Atlanto-axial dislocations (AADs) are potentially fatal disturbances with high spinal cord compression syndrome. As surgeons are still uncertain who is likely to benefit the most from surgery, a prediction tool is needed to provide decision-making support. Methods The model was established based on 108 patients with AADs using multiple binary logistic regression analysis and evaluated by calibration plot and the area under the receiver operating curve (AUC). Bootstrapping was used for internal validation...

On March 11, 2011, an earthquake (magnitude 9.0) devastated Japan's east coast, and the associated tsunami resulted in social and mechanical destruction. Search for the missing people is still ongoing. Surgical implants are common in the general population. Medical implants usually have lot numbers, and their forensic use is common for victim identification. This investigation was conducted mainly in the cities of Kamaishi and Otsuchi, both of which were affected by the tsunami disaster in 2011. We visited 6 mortuaries with the police between March 20 (9 days after the tsunami) and April 20 (40 days after the tsunami) to examine the presence of surgical scars and related information...

BACKGROUND: Obesity is a major health problem worldwide and is associated with complications after total knee arthroplasty (TKA). It remains unknown whether a change in body mass index (BMI) after primary TKA affects the reasons for revision TKA or the time to revision TKA. METHODS: A total of 160 primary TKAs referred to an academic tertiary center for revision TKA were retrospectively stratified according to change in BMI from the time of their primary TKA to revision TKA...

Background and purpose - There is increasing evidence that several commonly performed surgical procedures provide little advantage over nonoperative treatment, suggesting that doctors may sometimes be inappropriately optimistic about surgical benefit when suggesting treatment for individual patients. We investigated whether attitudes to risk influenced the choice of operative treatment and nonoperative treatment. Methods - 946 Swedish orthopedic surgeons were invited to participate in an online survey. A radiograph of a 4-fragment proximal humeral fracture was presented together with 5 different patient characteristics, and the surgeons could choose between 3 different operative treatments and 1 nonoperative treatment...

Pseudoarthrosis, or nonunion, of the long bones is a challenging medical condition for orthopedic surgeons to treat. Therefore, healing enhancer materials are commonly used. The authors investigated whether platelet-rich fibrin accelerates long bone healing by comparing radiological and histological findings in a rat model of open femoral fracture. Platelet-rich fibrin is a current biomaterial that contains many growth factors and platelets. There are no studies in the literature investigating the effects of platelet-rich fibrin on fracture healing...

INTRODUCTION: Informal (hallway) medical consultation is an integral part of the physician's work. As musculoskeletal complaints are very common, orthopedic surgeons stand in the frontline of this practice. Many of these consultations are poorly, if at all, documented, thus imposing a potential medical danger to the patient and a medicolegal danger to the surgeon. We conducted this first study to examine whether this practice is common among the orthopedic surgeons in university hospital...

Orthopedic trauma surgery is a critical component of resident education. Surgical case logs obtained from the Accreditation Council of Graduate Medical Students from 2009 to 2013 for orthopedic surgery residents were examined for variability between the 90(th) and 10(th) percentiles in regards to the volume of cases performed. There was an upward trend in the mean number of cases performed by senior residents from 484.4 in 2009 to 534.5 in 2013, representing a 10.3% increase. There was a statistically significant increase in the number of cases performed for humerus/elbow, forearm/wrist, and pelvis/hip during this period (P<0...

BACKGROUND: We recently reported that tranexamic acid (TXA) evokes pain in rats by inhibiting γ-aminobutyric acid and glycine receptors on neurons in the spinal dorsal horn. Although TXA is commonly used to reduce perioperative blood loss during various surgeries, its potential to induce intraoperative nociception, thereby increasing the need for more analgesics during surgery, has not been investigated. Therefore, this study aimed to investigate whether TXA evokes pain and increases the need for a higher infusion rate of remifentanil in patients undergoing surgery for adolescent idiopathic scoliosis (AIS)...

BACKGROUND: Maximizing operating room utilization in orthopedic and other surgeries relies on accurate estimates of surgical control time (SCT). A variety of case and patient-specific variables can influence the duration of surgical time during revision total hip arthroplasty (THA). We hypothesized that these variables are better predictors of actual SCT (aSCT) than a surgeon's own prediction (pSCT). METHODS: All revision THAs from October 2008 to September 2014 from one institution were accessed...
