Medtronic’s New CD Horizon Fenestrated Screw Spinal System

Medtronic launched the CD HORIZON Fenestrated Screw Spinal System, initially making it available in Europe.  The device features screws through which bone cement can be injected to establish an anchor for the screws within fragile, osteopenic bones. MedGadget

Earlier exit from hospital after hip operation

Discharged from the hospital within two days of a total hip replacement operation? It’s possible, thanks to the new 'Fast Track' protocol that underwent testing in the U.S., in response to both patient requests for shorter hospital stays and economic realities of providing medical care. According to Dr. Lawrence Gulotta and colleagues, from Hospital for Special Surgery in New York, a carefully screened group of patients undergoing total hip replacement can be discharged from the hospital two days after surgery, without any increase in complications or adverse effects compared with the more traditional protocol. Their work is published online in Springer's HSS Journal. Springer

Review: minimally invasive versus conventional dynamic hip screw fixation in elderly patients with intertrochanteric fractures: a systematic review and meta-analysis.

There was no significance difference between the 2 groups with regard to postoperative complications and implant position. The MIDHS technique may achieve perioperative benefits when compared with the CDHS technique. Tao Cheng, Guoyou Zhang, Xianlong Zhang. Surg Innov. 2011 Jun;18(2):99-105. PMID: 21712233

Surgical repair of the distal biceps brachii tendon: a comparative study of three surgical fixation techniques.

In summary, we achieved good clinical and functional results after surgical repair of the distal biceps tendon using Corkscrews, Mitek anchors, or transosseous sutures. The results conferred by Corkscrews were comparable to the other techniques, justifying their use. Citak M, Backhaus M, Seybold D, Suero EM, Schildhauer TA, Roetman B.

Evidence-based treatment of open ankle fractures.

There is a lack of high quality literature concerning the (operative) treatment of patients with open ankle fractures. Remarkable is that most authors reported satisfactory results after performance of their treatment protocol. Based on the available literature, we formulated guidelines regarding: timing of operative treatment, wound irrigation, the role of internal fixation, wound coverage and closure, the use of antibiotics and additional therapies.

Google+ for doctors, and why physicians should be careful

So, how should physicians handle Google+?

Similar to the way doctors should use Facebook.  I’ve recommended in the past that physicians maintain two profiles, a personal one to share only with close family and friends, and a professional page that is open to the public.  As far as I can tell, Google+ offers no such personal-professional differentiation.  So if you join, it’s imperative that your pictures and personal content be well-vetted before you post.  Since this is a Google product, there’s a greater chance that what’s found on Google+ will be indexed in the search engine.

Google Circles has the potential to be that application to isolate your professional identity (you can selectively share content with different groups), and physicians need to be vigilant in using that feature.  For now, be careful about what you put on your Google Profile.

Surgical simulators and hip fractures: a role in residency training?

Orthopedic surgery residency training requires intellectual and motor skill development. In this study, we utilized a computer-based haptic simulator to examine a potential model for evaluation of resident proficiency and efficiency in the placement of a center guide wire during fixation of an intertrochanteric proximal femur fracture. We hypothesize the junior residents will utilize more fluoroscopy and require more time to complete the task. Froelich JM, Milbrandt JC, Novicoff WM, Saleh KJ, Allan DG.

Surgical Technique: Revision ACL Reconstruction With a Rectangular Tunnel Technique.

We developed the rectangular tunnel ACL reconstruction (RT ACLR) using a 10-mm wide bone-patellar tendon-bone (BTB) graft through rectangular tunnels with a rectangular aperture to reduce tunnel size: the cross-sectional area of the tunnels of 50 mm(2) (5 × 10 mm) in RT ACLR is less than that of 79 mm(2) in a conventional 10-mm round tunnel technique presuming the technique would be more suitable in revision ACLR with previous improperly placed tunnels.

Osteoarthritis incidence significantly higher among US military personnel

New research shows significantly higher osteoarthritis (OA) incidence rates in military populations than among comparable age groups in the general population. The magnitude of the difference in OA rates between military service members and the general population also increased with advancing age category. Black service members had higher OA rates than white military personnel or those in other race categories according to the study findings published in Arthritis & Rheumatism, a peer-reviewed journal of the American College of Rheumatology (ACR).  Eurekalert!

Complications following autologous bone graft harvesting from the iliac crest and using the RIA: A systematic review.

Bone grafting is a commonly performed surgical procedure to augment bone regeneration in a variety of cases in orthopaedic and maxillofacial surgery. Autologous bone graft remains to be the 'gold standard' and the iliac crest to be the most common harvesting site. The intramedullary canal of long bones represents another potential site for large volume of autologous bone graft harvesting and is recently being used as an alternative donor site. However, harvesting of autologous bone graft is associated with morbidity and a number of complications. The aim of this systematic review was to collect and summarise the existing data on reported complications after harvesting autologous bone from the iliac crest (anterior and posterior) and the long bone intramedullary canal using the RIA device. Dimitriou R, Mataliotakis GI, Angoules AG, Kanakaris NK, Giannoudis PV.

The hidden costs of your favorite medical apps

Medical apps are becoming big business. Epocrates is now a publicly traded company worth nearly $500 million. Medscape is owned by WebMD, another publicly traded company worth nearly $3 billion. Despite the clearly powerful financial factors at play here, the most popular and comprehensive apps are free. Even for fee-based apps, the prices and volumes don’t explain the overall financial pictures of the companies behind them. Clearly the money is not coming from the physicians, medical students, and other healthcare professionals who are using these apps. iMedicalApps

Fracture status in men assessed by quantitative ultrasound measurements at the calcaneus.

Objectives- The aim of the study was to assess fracture status in men by quantitative ultrasound measurements at the calcaneus. The diagnostic accuracy of quantitative ultrasound measurements was evaluated at baseline and follow-up. Methods- We observed 165 men (baseline age ± SD, 59.84 ± 10.6 years) recruited from an outpatient osteoporosis clinic. The mean follow-up duration was approximately 101.3 ± 35 months. There was no difference in either age or body mass index at baseline between the patients with a fracture history (n = 30) and the others (n = 135). The following fractures were identified at baseline: ankle, 15; wrist, 10; rib, 9; foot, 5; and hip, 1. The speed of sound (meters per second), broadband ultrasound attenuation (decibels per megahertz), and stiffness index (percent) were measured with a quantitative ultrasound device. The date of fracture occurrence at follow-up was defined as the final point. Results- In the patients with a fracture history, the ultrasound variables were significantly lower than those in the rest of the group (P < .05). During the follow-up period, fractures occurred in 21 patients (wrist, 11; ankle, 5; rib, 3; hip, 1; and humerus, 1), and the ultrasound outcomes were nonsignificantly lower in the fractured men. The risk of fracture was estimated by the Cox regression analysis. A prior fracture was the only factor that significantly (4 times) increased the risk of a subsequent fracture (hazard ratio, 4.21; 95% confidence interval, 1.81-9.86; P < .001). Conclusions- Calcaneus ultrasound measurements can distinguish between patients with fractures and those without. In follow-up, ultrasound measurements did not indicate an increased fracture risk; a prior osteoporotic fracture was the major prognostic factor.

Primary internal fixation and soft-tissue reconstruction in the treatment for an open Lisfranc fracture-dislocation.

The importance of anatomical reduction for improved outcome has been recognised in the management of Lisfranc injuries. Operative fixation is indicated in case of dislocation or unstable ligamentous injury, because discongruity of the Lisfranc joint can lead to deleterious functional outcome. Screws are the recommended method of fixation of the medial en middle column, and K-wires are used for stabilisation of the unstable lateral column. Primary arthrodesis can provide advantages in pure ligamentous injury. In the management of complex open Lisfranc fractures, external fixation with K-wires can be used, but often results in a high percentage of arc deformities and functional limitations. In recent years, there is a progressive change from external to internal fixation in primary stabilisation of open fractures. This case report describes the treatment for a grade III open Lisfranc fracture-dislocation by use of primary internal fixation and soft-tissue reconstruction. Sanli I, Hermus J, Poeze M.

Hip fracture management, before and beyond surgery and medication: a synthesis of the evidence.

Multidisciplinary medical management of patients with hip fractures is being improved within the hospital environment resulting in earlier discharge with decreased morbidity. There is evidence to show the benefits to patients with hip fractures from peripheral modalities within the hospital; however unless resident in a facility, multidisciplinary management is not clearly of benefit.

Military static line parachuting injuries seen by the airborne battalion provider.

Military static line parachuting exposes jumpers to a variety of novel methods of injury. Providers assigned to Airborne units need to develop and maintain a high index of suspicion when dealing with jump-related injuries. Understanding the incident rate and the mechanism of injury can help a provider better identify injuries based on the history of the incidence and develop that index of suspicion. Injuries can happen at almost any point during the jump process and each step has both common and unique injuries associated with it. In addition to identifying, managing, and treating the injuries involved, providing information on estimated time until return to duty can be beneficial for the commander. In the end, a provider?s best tools for managing Airborne-related injuries are an understanding of Airborne operations, quality orthopedic skills, and a high index of suspicion. Healy ML.
