Three hips in two patients required secondary revision surgery for residual acetabular dysplasia with combined pelvic osteotomy and femoral osteotomy. Seven of the hips that had been operated on showed signs of avascular necrosis (AVN). Among them, four were degree II, two were degree III, and one was degree IV. Multiple linear regression analysis demonstrated that greater age (in months) heightened the risk for secondary revision surgery (P = 0.032). CONCLUSIONS The modified Smith-Petersen approach preserving the rectus femoris is an encouraging and safe option for treating hip dislocation in young AMC patients (before 12 months). If surgery takes place at less than 12 months of age for patients with AMC, this earlier open reduction for hip dislocation may reduce the chances of secondary revision surgery. LEVEL OF EVIDENCE IV, retrospective non-randomized study.BACKGROUND The incidence of periprosthetic fractures after total knee arthroplasty (TKA) is rising due to the increasing number of TKAs performed annually and the growing elderly population. A periprosthetic fracture of the proximal tibia following TKA is a rare injury that may be a challenging clinical scenario. CASE PRESENTATION The case of an 84-year-old woman who sustained a periprosthetic tibial fracture 10 years after a TKA is presented. This patient had multiple risk factors. The fracture was not deemed amenable to conventional treatment because the bone fragment was too small. This patient underwent fixation of her tibial fracture above the TKA using a five-ring Ilizarov external fixator. This allowed immediate full weight-bearing. The fixator was removed at 12 weeks, at which time the fracture was solidly healed. At the most recent follow-up, 2 years from injury, she was fully weight-bearing without walking aids and had a knee range of motion (ROM) of 0-110°. CONCLUSION To the best of our knowledge, this is the first report in which Ilizarov external fixation has been used for a periprosthetic tibial fracture after TKA.BACKGROUND Anterior cervical spine surgery is often associated with postoperative dysphagia, but chronic dysphagia caused by laryngo-vertebral synostosis is extremely rare. We report a case of chronic dysphagia caused by synostosis between the cricoid cartilage and cervical spine after anterior surgery for cervical spine trauma. CASE PRESENTATIONS We present a case of a 39-year-old man who had sustained complex spine trauma at C5-6 associated with complete spinal cord injury at the age of 22; the patient presented with a 5-year history of chronic dysphagia. Computed tomography demonstrated posterior shift of the esophagus as well as calcification of the cricoid cartilage and its fusion to the right anterior tubercle of the C5 vertebra. A barium swallow study demonstrated significant barium aspiration into the airway and no laryngeal elevation. The patient underwent resection of the bony bridge and omohyoid muscle flap insertion. His symptoms ameliorated after surgery. CONCLUSION Synostosis between the cricoid cartilage and cervical spine may occur associated with cervical spine trauma and causes chronic dysphagia. Resection of the fused part can improve dysphagia caused by this rare condition and omohyoid muscle flap might be a good option to prevent recurrence.BACKGROUND It has been shown that fears and misconceptions negatively affect the willingness to donate organs. Empirical studies have examined health communication strategies that serve to debunk these fears. There are promising indications that humor has the potential to influence health-related attitudes and behaviors. This study examines empirically whether medical cabaret, as a specific format for delivering health-related information in a humorous way, affects the willingness to donate organs. METHODS A quasi-experimental study was conducted among the audience of a medical cabaret live show. Participants in two intervention groups and one control group were interviewed just before the start of the live show (t0) and about 6 weeks later (t1). Intervention group 1 (I1) witnessed a ten-minute sequence by the cabaret artist about organ donation. Participants in I2 witnessed the sequence and, in addition, received an organ donor card. Descriptive statistics and t-tests were used to investigate changes in attitudes and the willingness to donate organs from t0 to t1. RESULTS A significant increase in the willingness to donate organs and an improvement in general attitude was observed in the intervention groups. Moreover, significantly more participants in I2 carried an organ donor card after the intervention. Some fears could be reduced, while understanding of the reasons for organ donation could be increased via the intervention. CONCLUSIONS The study confirms that medical cabaret is able to affect respondents' attitudes and behaviors even in the context of organ donation. Medical cabaret can enhance the willingness to donate organs and dispel negative concerns.BACKGROUND Varus malalignment of the tibia could alter ankle biomechanics, and might lead to degenerative changes of the ankle joint. However, previous studies failed to report the detailed changes of ankle biomechanics in varus malalignment of the tibia. The aim of this biomechanical study was to evaluate how the ankle joint pressure would change in response to the incremental increases in varus malalignment of the tibia. METHODS Eight fresh-frozen human cadaver legs were tested in this study. Procoxacin Varus malalignment of the tibia and a total of 600 N compressive force was simulated using a custom made fixture. Intra-articular sensors (TeckScan) were inserted in the ankle joint to collect the ankle joint pressure data. The testing sequence was 0°, 2°,4°,6°,8°,10°,12°,14°,16°,18°,20° of tibial varus. RESULTS As the tibial varus progressed, the center of force (COF) shifted laterally both for the medial and lateral aspect of the ankle joint. For the medial aspect of the ankle joint, the lateral shift reached its maxthe lateral stress concentration decreased.BACKGROUND This study evaluated and compared the extent, duration, contents, experiences and effects of alcohol conversations in healthcare in the Netherlands and Sweden in 2017. METHODS Survey data in the Netherlands and Sweden were collected through an online web panel. Subjects were 2996 participants (response rate 50.8%) in Sweden and 2173 (response rate 82.2%) in the Netherlands. Data was collected on socio-demographics, alcohol consumption, healthcare visits in the past 12 months, number of alcohol conversations, and characteristics of alcohol conversations (duration, contents, experience, effects). RESULTS Results showed that Swedish respondents were more likely to have had alcohol conversations (OR = 1.99; 95%CI = 1.64-2.41; p =  less then  0.001) compared to Dutch respondents. In Sweden, alcohol conversations were more often perceived as routine (p =  less then  0.001), were longer (p =  less then  0.001), and more often contained verbal information about alcohol's health effects (p = 0.007) or written information (p = 0.
