Orthopedic boot camp: examining the effectiveness of an intensive surgical skills course.

The intensive skills course used in this study was highly effective at teaching and developing targeted surgical skills in first-year orthopedic residents. We predict that allowing residents to acquire key technical skills at the start of their training will enhance learning opportunities at later stages of training.

Use of vacuum-assisted closure (VAC™) in high-energy complicated perineal injuries: analysis of nine cases.

Our study reviewed nine patients who were treated with the VAC™ Abdominal Dressing System after suffering pelvic fractures and soft tissue loss after high-energy pelvic trauma. Between March 2008 and August 2009, our clinic treated nine patients with complicated perineal injuries from high-energy pelvic trauma with multiple irrigation and debridement procedures and broad-spectrum antibiotics. Protective ostomies were created for all nine patients. Ozer MT, Coskun AK, Ozerhan IH, Ersoz N, Yildiz R, Sinan H, Demirbas S, Kozak O, Uzar AI, Cetiner S.

Return to running and sports participation after limb salvage.

The ability to return to running and sports participation after lower extremity limb salvage has not been well documented previously. Although the ability to ambulate without pain or assistive devices is generally a criteria for a good limb salvage outcome, many patients at our institution have expressed a desire to return to a more athletic lifestyle to include running and sports participation. The purpose of this study was to investigate the types of athletic endeavors our high-energy lower extremity trauma patients were able to pursue after limb salvage.

Coracoid Fractures: Therapeutic Strategy and Surgical Outcomes.

The majority of type I coracoid fractures set out in Ogawa's classification constitute double disruption of the superior shoulder suspensory complex (SSSC) as proposed by Goss, frequently resulting in healing delay and adverse functional consequences. However, there are few reports alluding to strategies or concrete treatment methods of such injuries. The purpose of this report is to introduce our surgical strategy for treating the type I coracoid fracture with concurrent injuries and to describe our treatment method with their outcomes.

Revision Surgery for Patellofemoral Problems: Should We Always Resurface?

Bicompartmental knee arthroplasties had higher revision rates than TKAs. Femoral component design did not influence the cumulative revision rate. Secondary patella resurfacing in a bicompartmental knee arthroplasty carried an increased revision risk compared to resurfacing at the time of index TKA. To reduce the probability of reoperation for patellofemoral problems, our data suggest the patella should be resurfaced at the time of index surgery. Johnson TC, Tatman PJ, Mehle S, Gioe TJ.

Hip Implant Complaints Surge, Even as the Dangers Are Studied

The federal government has received a surge in complaints in recent months about failed hip replacements, suggesting that serious problems persist with some types of artificial hips even as researchers scramble to evaluate the health dangers. An analysis of federal data by The New York Times indicates that the Food and Drug Administration has received more than 5,000 reports since January about several widely used devices known as metal-on-metal hips, more than the agency had received about those devices in the previous four years combined.

Suture anchor versus screw fixation for greater tuberosity fractures of the humerus—a biomechanical study

Suture anchors and screws are commonly used for fixation of humeral greater tuberosity (GT) fractures in either arthroscopic or open surgeries, but no biomechanical studies have been performed to compare the strength of fixation constructs using these two implants. This cadaveric study aimed to compare the biomechanical strength of three different fixation constructs in the management of GT fractures: Double-Row Suture Anchor Fixation (DR); Suture-Bridge Technique using suture anchors and knotless suture anchors (SB); and Two-Screw Fixation (TS).

A 40-month multicentre, randomised placebo-controlled study to assess the efficacy and carry-over effect of repeated intra-articular injections of hyaluronic acid in knee osteoarthritis: the AMELIA project.

The results of AMELIA offer pioneer evidence that repeated cycles of intra-articular injections of HA not only improve knee osteoarthritis symptoms during the in-between cycle period but also exert a marked carry-over effect for at least 1 year after the last cycle. In this respect, it is not possible to establish if this carry-over effect reflects true osteoarthritis remission or just a modification of the disease's natural course.

One resident's experience designing and running a randomized control trial in orthopedic surgery.

All ACGME-accredited orthopedic residency programs require residents to participate in research during their training. The levels of evidence adopted for clinical research validate the randomized clinical trial (RCT) as the gold (Level 1) standard. While many residents aspire to conduct or be involved in an RCT during their orthopedic training, I would like to describe my experience as an orthopedic surgery resident designing and running an RCT.

Military Malpractice System Needs Overhaul

Reform of the existing administrative approach to malpractice offers the best hope to improve the military's response to medical injury compensation for veterans, health policy specialists suggested.
For more than 60 years, prevailing doctrine has maintained a "seemingly indefensible inequity between civilians and active-duty service members injured as a result of malpractice." However, eliminating the doctrine would simply "replace one injustice with another," according to an article in the August 18 issue of the New England Journal of Medicine. (PDF) via Medpage Today

Closed Reduction and Early Mobilization in Fractures of the Humeral Capitellum.

Seven consecutive patients with an isolated fracture of the humeral capitellum were treated by a single surgeon at a Level II care facility according to a simple treatment algorithm. Closed reduction was attempted in all cases using a standard technique. After reduction, the arm was splinted at 90° of flexion and mobilized at 14 days. All patients completed a clinical and radiographic follow-up consisting of a radiographic evaluation of reduction, elbow range of motion, Disabilities of the Arm, Shoulder and Hand Questionnaire, and a subjective rating of patient satisfaction. None of the patients required conversion to open reduction internal fixation or excision. Disabilities of the Arm, Shoulder and Hand Questionnaire scores ranged from 6 to 13 points (out of 100; mean, 9). The mean flexion/extension arc of motion obtained was 126° with minimal loss of rotation. Patient satisfaction was rated as excellent in five patients and good in two. All fractures appeared united at the most recent clinical and radiographic review. Closed reduction and early mobilization appears to be a safe and effective method of treating displaced fractures of the humeral capitellum with clinical results comparable to that of open reduction internal fixation.

Towards an assessment of bone fracture healing using pulsed mode ultrasound.

Healing rate of fractured bone differs from one patient to another which may lead to incorrect consequent medical procedures. Thus, quantitative assessment of bone healing after fracture becomes important. In this paper, we present a mathematical model which describes the interaction of a pulsed mode ultrasound waves with a multilayered biological structure. The model is applied to estimate the bone callus thickness and degree of hardness. Different frequencies are utilized to obtain highest measurement sensitivity and accuracy of callus thickness and degree of hardness. It is found that a transducer operating at 1 MHz has the highest sensitivity to the different phases of callus hardening. On the other hand, a 3 MHz transducer yields the highest sensitivity to the thickness of the callus layer. Thus, using both frequencies might prove to be useful for full quantitative assessment of the bone healing process. Qaddoumi N, Al-Nashash H, Sediq AB, Al-Shamsi H, Al-Mehrizi M, Khalaf K.

New 'bionic' leg gives amputees a natural gait

A new lower-limb prosthetic developed at Vanderbilt University allows amputees to walk without the leg-dragging gait characteristic of conventional artificial legs.

The device uses the latest advances in computer, sensor, electric motor and battery technology to give it bionic capabilities: It is the first prosthetic with powered knee and ankle joints that operate in unison. It comes equipped with sensors that monitor its user's motion. It has microprocessors programmed to use this data to predict what the person is trying to do and operate the device in ways that facilitate these movements. Eurekalert!

Fujifilm releases radiology viewing app, allows physicians and radiologists to view medical images on the go

Fujifilm Synapase Mobility is now available in the U.S., and not just on the iPhone, but for the Android and iPad as well. Fujifilm makes a variety of medical images devices, from ultrasound devices to computed radiology devices (x-rays).

The microbiological basis for a revised antibiotic regimen in high-energy tibial fractures: Preventing deep infections by nosocomial organisms

Following high-energy open fracture, a single prophylactic antibiotic regimen directed against environmental wound contaminants does not provide cover for the organisms responsible for deepest SSI's and may have depopulated the niche, promoting nosocomial contamination prior to definitive closure. We advocate a dynamic prophylactic strategy, tailoring a second wave of prophylaxis against nosocomial organisms at the time of definitive wound closure, and at the same time avoiding the potential complications of prolonged antibiotic use.

Disability system leaves troops in 'vast unknown'

The government determines the pay and benefits given to wounded, sick or injured troops for their military service. Under the old system, a medical board would determine their level of military compensation and the service member would be discharged. Then the veteran essentially would have to go through the process again with the Veterans Affairs Department to determine benefits. While they waited for their VA claim to be processed, many of the war wounded were going broke.

Under the new system, which started in 2007 and will be completely rolled out at military bases nationwide by the end of September, the service member essentially goes through both disability evaluation systems at the same time before leaving the military. AP

New compound may accelerate bone healing, prevent osteoporosis

Hiroki Yokota, professor of biomedical engineering at Indiana University-Purdue University Indianapolis (IUPUI) and adjunct professor of anatomy and cell biology at the IU School of Medicine, will investigate the effect of salubrinal -- a chemical compound originally developed to encourage insulin production in individuals with diabetes -- on human bone strength and growth. Early laboratory research supported by the Indiana Clinical and Translational Sciences Institute (CTSI) suggests weakened bones treated with salubrinal experience a statistically significant increase in strength, as well as accelerated healing in bones that have been fractured.

The prevalence and effect of publication bias in orthopaedic meta-analyses.

Meta-analyses of randomized, controlled trials are considered the highest level-of-evidence, thus strongest source of information. However, questions concerning the validity of meta-analyses in orthopaedic surgery emerged recently. Among the most common sources for errors is publication bias. This describes the fact that studies with small or non-significant outcomes are less likely to be published, thus less likely to be identified and included in systematic reviews and meta-analyses. In this study we asked three questions: (1) Whether publication bias is assessed in orthopaedic meta-analyses, (2) What the actual prevalence of publication bias is, and (3) what effect publication bias has on the outcomes of orthopaedic meta-analyses.

Orthopedic surgery in the United States Army: a historical review.

The contribution of American military surgeons to the development of orthopedic surgery has not previously been explored. The experiences of American military surgeons in conflicts from the Civil War to Iraq and Afghanistan have advanced the orthopedic discipline, resulting in important developments within the field, as well as scientific discoveries that have benefited both the civilian and military communities. From advances in wound care, to spinal surgery, intramedullary nailing of long bone fractures, and external fixation, American military surgeons have been pioneers of orthopedic surgery. The goal of this review was to survey the American military orthopedic experience from the American Revolution to the wars in Iraq and Afghanistan. Schoenfeld AJ. Mil Med. 2011 Jun;176(6):689-95.

Biomechanical Comparison of Arthroscopic Repairs for Acromioclavicular Joint Instability: Suture Button Systems Without Biological Augmentation.

Isolated reconstruction of the CC ligaments using single and double clavicular tunnel techniques results in a high load to failure for superior translation, which is equal to the native stability, and less translation in all 3 directions as well as higher superior stability when compared with the modified Weaver-Dunn procedure. A potential drawback is the risk of coracoid fracture, as the high load to failure of the device may exceed load to failure of cortical bone prior to device breakage. Clinical Relevance: Single clavicular tunnel arthroscopic reconstructions of the coracoacromial ligaments show good biomechanical results.

Given the well-recognized imperative to treat hip fractures as expeditiously as possible, there can arise uncertainty regarding the balance between preoperative medical optimization and delay of surgery. Echocardiography is often felt to considerably delay surgery with limited change to patient management.

Ultrasound in the selective screening of developmental dysplasia of the hip.

Developmental dysplasia of the hip (DDH) can result in chronic pain, gait abnormalities and degenerative arthritis. Infants with a family history, Breech delivery or unstable/"clicking" of the hip on examination are at higher risk. The goal is to detect cases early enough for normal hip development and function by the end of adolescence, but clinical examination alone is ineffective.

MR evaluation of femoral neck version and tibial torsion.

Abnormalities of femoral neck version have been associated with a number of hip abnormalities in children, including slipped capital femoral epiphysis, proximal femoral focal deficiency, coxa vara, a deep acetabulum and, rarely, developmental dysplasia of the hip. Orthopedic surgeons also are interested in quantifying the femoral neck anteversion or retroversion in children especially to plan derotational osteotomies. Historically, the angle of femoral version and tibial torsion has been measured with the use of radiography and later by CT. Both methods carry with them the risks associated with ionizing radiation. Techniques that utilize MR are used less often because of the associated lengthy imaging times. This article describes a technique using MRI to determine femoral neck version and tibial torsion with total scan times of approximately 10 min.

A Doctor’s Review of the Android HTC Flyer as a Medical Tablet

The HTC Flyer promises to be the perfect medical tablet: it supports a fine-tip stylus and is small enough at 7 inches to comfortably carry around in a white coat. The recently reviewed BlackBerry PlayBook impressed with its size (also 7 inches), but ultimately suffered from its lack of third party apps. The HTC Flyer offers the potential of the growing Android marketplace and its many medical apps, so I was thrilled to purchase one for review. One of the two tablets earned a permanent spot in my white coat. Read on to find out which one and why. iMedicalApps

NYU Langone experts find MRI techniques can detect early osteoarthritis

Researchers from NYU Langone Medical Center's Departments of Orthopaedic Surgery and Radiology found that advanced MRI techniques can be used to detect subtle changes in joint cartilage microstructure – and provide physicians a diagnostic tool for finding key markers of early osteoarthritis (OA). By using these techniques during patient exams to identify OA earlier, clinicians can shift the management of the disease from eventual joint reconstruction to long-term preservation. The study was published in the July issue of the Journal of the American Academy of Orthopaedic Surgeons. Eurekalert! PDF

'Windmill of War' about pain, moving forward

"(It) is called ‘Windmill of War,' because no matter what's going on with the outside world these men are like a windmill, they just keep turning and moving and going to wherever they're needed," Gehrig said of her patient and all war veterans.

Thanks to medical advancements in the field and orthopedic surgeons like Gehrig, orthopedic patients across the country are able to move forward in their lives as normally as possible.

"The role an orthopedic surgeon plays in all this is the fact that we put their limbs together and they can then function after they heal," Gehrig said.

The American Academy of Orthopaedic Surgeons strives to showcase stories like Gehrig's patient's through the "Wounded in Action" art exhibit. Shown across the country, the exhibit has pieces from orthopedic surgeons and veterans who know what it is like to undergo such a life-changing experience.

Though Gehrig says that "Windmill of War" is a personal expression of how she feels toward her patients, it also is a call for all to take another look at those who have put their lives on the line for Americans.

"You can't really appreciate it until you hear some of the stories and see some of the residue of war and miracles happen with some of these injuries," Gehrig said. Bismarck Tribune

Sailors can wear ‘toe shoes’ despite military medical warnings

The Navy has reversed its policy banning minimalist 'toes shoes', Military Times reported. According to a fleetwide message released Aug. 5, sailors can wear the popular glove-like shoes, even during physical readiness tests, the newspaper reported.

However, the Navy Bureau of Medicine and Surgery has expressed concerns about the bare-bones Vibram Fivefingers shoes and warned against their use, according to Military Times.

While the Army banned soldiers from wearing the shoes during training earlier this summer, according to The Washington Post, the military school system endorsed them in March.

Interventions for treating chronic ankle instability.

Neuromuscular training alone appears effective in the short term but whether this advantage would persist on longer-term follow-up is not known. While there is insufficient evidence to support any one surgical intervention over another surgical intervention for chronic ankle instability, it is likely that there are limitations to the use of dynamic tenodesis. After surgical reconstruction, early functional rehabilitation appears to be superior to six weeks immobilisation in restoring early function. de Vries JS, Krips R, Sierevelt IN, Blankevoort L, van Dijk CN.

Mobile Devices and Medical Liability: Some Important Considerations

As mobile devices become more and more integrated into clinical practice, our health system will have to not only figure out how this technology will change the face of medicine, but also how it will change the system of medical liability. Physicians and administrators alike shudder at the thought of malpractice, but considering the fact that 60% of physicians over the age of 55 have been sued at least once during their career, we have to carefully think about how all of our new tools fit into the liability picture. Michelle Mello, a Harvard health law professor, offered some insight at the World Congress Leadership Summit on mHealth. iMedicalApps

Associations between repeated deployments to OEF/OIF/OND, October 2001-December 2010, and post-deployment illnesses and injuries, active component, U.S. Armed Forces.

Since 2001, 1,347,731 U.S. military members have deployed to Afghanistan or Iraq; of these, approximately 40% deployed to Afghanistan or Iraq more than once. We assessed relationships between multiple deployments and diagnoses of diseases and injuries (as defined by 3-digit ICD-9-CM codes) among all male and female deployers within one year after returning from first through fifth deployments. For most illnesses and injuries, the proportions of deployers affected within one year post-deployment hardly varied in relation to the number of prior deployments. Back and joint disorders, sleep disorders, hypercholesterolemia, hypertension, chronic sinusitis, and allergic rhinitis were "excessive" among repeat compared to first-time deployers. Some conditions may be caused or exacerbated by repeat wartime deployments. On the other hand, repeat deployments may select for the most inherently resilient service members and/or incrementally increase the resilience of repeat deployers.

The Modern "Deck-Slap" Injury-Calcaneal Blast Fractures From Vehicle Explosions.

Calcaneal injuries following under-vehicle explosions are commonly associated with significant multiple injuries including severe lower limb injury. The frequency of associated spinal injuries mandates radiologic evaluation of the spine in all such patients. The severity of the hindfoot injury is reflected by the high infection rate and amputation rate. Only a small proportion of casualties were able to return to preinjury military duties.
