1581. Fixation Using Alternative Implants for the Treatment of Hip Fractures (FAITH-2)

all patients require surgical repair of their fractures and unlike elderly hip fractures, failure of surgery offers few options for salvage. Arthroplasty is a successful treatment for elderly patients; however, a hip replacement is not a viable option for younger patients because of their higher functional demands for work and recreational activities that are not tolerated by joint replacements. There is more than one way to perform internal fixation for femoral neck fractures. Cancellous screws (...) , musculoskeletal health, and improved fracture healing. Experimental animal studies have demonstrated the concentration of vitamin D metabolites are higher at a fracture callus compared to the uninjured contralateral bone, vitamin D supplementation leads to decreased time to fracture union and increased callus vascularity, and vitamin D increases mechanical bone strength compared to controls. Clinical studies have also demonstrated that vitamin D supplementation increases the callus volume of proximal humerus

transplantation of autologous osteoperiosteal cylinder graft, which was harvested from the ipsilateral iliac crest. The visual analog scale score for pain during daily activities, American Orthopaedic Foot & Ankle Society hindfoot and ankle scores, and subjective satisfaction survey rating were obtained. Plain radiographs and magnetic resonance imaging of the ankle were obtained before and after surgery. In 13 cases second-look arthroscopy was performed 12 months postoperatively and the cartilage repair (...) was assessed with the criteria of the International Cartilage Repair Society.Sixteen patients were available for follow-up at a mean of 32.6 months (range, 24 to 48 months). The mean visual analog scale score decreased from 5.51 ± 0.83 preoperatively to 0.98 ± 0.98 at the latest follow-up, and the median American Orthopaedic Foot & Ankle Society score improved from 75 preoperatively to 90 at the latest follow-up. Seven patients resumed sporting activities. Overall, 7 patients rated the result as excellent

1583. The effect of caffeine ingestion on skill maintenance and fatigue in epee fencers. (Abstract)

The effect of caffeine ingestion on skill maintenance and fatigue in epee fencers. The ergogenic effect of caffeine on sports performance focuses predominantly on endurance sports (Doherty & Smith, 2004 ) with little research on intermittent high intensity sports. This study aimed to explore the effect of caffeine ingestion on skill maintenance following fencing simulated exercise. Eleven competitive fencers participated (four female; seven male; age 33 ± 6.5 years). Following a maximal test (...) to exhaustion, fencers completed two trials assessing accuracy and reaction times (Stroop test) before and after a fatiguing protocol designed to simulate the demands of a fencing competition. Skill testing involved 30 lunges to hit a target. 500 ml placebo or 3 mg · kg(-1) caffeine supplemented drink was administered after the initial reaction and skill tests in a single-blind crossover design. The fatiguing protocol involved simulating six fights with 6-minute rests between each. Fencers rated

been tailored for these populations. Like athletes, warfighters consider protein a critical component of their diet and often incorporate protein supplements into daily diet plans. This article highlights sports nutrition principles that target energy and protein needs of athletes, considers the basis of these recommendations in the context of protein supplementation, and asserts that translating these recommendations to the warfighter is appropriate and necessary. The recommended range of protein (...) Training table to the battlefield: protein recommendations for warfighters. Warfighters represent a population of athletes for whom routine training and physical expectations for military operations parallel, and very often exceed, those of their civilian counterparts.

Atkins actually weight around 200 pounds through most of his life and a hospital note on admission showed him weighing 195 pounds. A substantial weight gain of 63 pounds occurred in the 9 days after his admission due to the accumulation of fluid volume and swelling which is not uncommon in the critically ill. No autopsy was performed on Atkins but the NYME wrote on the document that he had “h/o of MI, CHF, HTN.” MI is the acronym for a myocardial infarction or heart attack. As far as we

Sometimes the torn portion of the meniscus is simply removed. This tear is displaced and caught between the two bones

Also, why are the only resources you referenced in this journey woefully outdated?” I wouldn’t say I was engaging in hard and heavy exertion during my week in ketoland; walking a couple of miles to and from a restaurant or riding my bike at a moderate pace plus weights was the extent of it.

Around 10 years ago I got on the sports drink/carb loading thing and I’m pretty sure it was a big part of my weight gain issues.

However, results from small clinical trials of milk thistle for liver diseases have been mixed, and two rigorously designed studies found no benefit.” Please keep in mind that herbal remedies and supplements are not regulated so you don¹t really know for sure what is in them, and that the contents could change from one bottle to the next. The other problem is there is typically NO evidence (no clinical trials or data) to back up a claim for a cure, which is why the NIH fact sheets are so
