BACKGROUND: While studies have shown that postoperative wound complications can predispose to deep infection following orthopedic surgery, the best form of skin closure has not been elucidated. Furthermore, the unique risks and benefits of each type of wound closure have not been studied. The goal of this study is to present the diagnosis and treatment of patients with allergic contact dermatitis (ACD) from 2-octyl cyanoacrylate, a skin adhesive commonly used in wound closure. METHODS: Twenty-nine patients with ACD to 2-octyl cyanoacrylate (Prineo, Ethicon, NJ) following elective orthopedic surgeries from 2013 to 2016 were retrospectively reviewed; this occurred in 29 of 6088 units of Prineo used at our institution, for an estimated incidence of 0...

Due to its real-time, non-radiation based three-dimensional (3D) imaging capabilities, ultrasound (US) has been incorporated into various orthopedic procedures. However, imaging artifacts, low signal-to-noise ratio (SNR) and bone boundaries appearing several mm in thickness make the analysis of US data difficult. This paper provides a review about the state-of-the-art bone segmentation and enhancement methods developed for two-dimensional (2D) and 3D US data. First, an overview for the appearance of bone surface response in B-mode data is presented...

Medical images are essential in modern traumatology and orthopedic surgery. Access to images is often cumbersome due to a limited number of workstations. Moreover, due to the tremendous increase of data, the time to review or to communicate images has also become limited. One approach to overcome these problems is to make use of modern mobile devices, like tablet computers, to facilitate image access and associated workflows. Ten orthopedic surgeons were equipped with an Apple iPad mini 2 and specialized viewing software for medical images...

Orthopedic research into chronic discogenic back pain has commonly focused on aging- and degeneration-related changes in intervertebral disc structure, biomechanics, and biology. However, the primary spine-related reason for physician office visits is pain. The ambiguous nature of the human condition of discogenic low back pain motivates the use of animal models to better understand the pathophysiology. Discogenic back pain models must consider both emergent behavioral changes following pain induction and changes in the nervous system that mediate such behavior...

In the United Kingdom approximately 80,000 total hip arthroplasties are undertaken on an average each year. The popularity and demand for this operation are continually increasing. Our understanding of arthroplasty surgery and its complications has evolved greatly, and as a result infection rates are undeniably at an all-time low. The increasing volume of operations being performed does, however, mean that we still continue to see an increased number of cases of infection. There is no doubt that periprosthetic joint infection (PJI) poses a complex clinical and diagnostic predicament to clinicians...

Metal allergy is an uncommon and poorly understood cause of failure of orthopedic implants. To the authors' knowledge, there have been no reports of the management of shoulder arthroplasty patients with metal allergy. The authors present their experience with the diagnosis and management of patients with metal allergy. Patients with metal allergy undergoing shoulder arthroplasty were identified through retrospective chart review from January 1, 2012, to January 31, 2015. Case characteristics collected included patient risk factors (age, sex, prior cutaneous reactions to metal), metal allergy factors (type of metal allergy, method of diagnosis), and surgery factors (implant type, primary/revision, type of shoulder arthroplasty)...

Percutaneous vertebroplasty procedure is of major importance, given the significantly increasing aging population and the higher number of orthopedic procedures related to vertebral compression fractures. Vertebroplasty is a complex technique involving the injection of polymethylmethacrylate (PMMA) into the compressed vertebral body for mechanical stabilization of the fracture. Our understanding and ability to modify these mechanisms through alterations in cement material is rapidly evolving. However, the rate of cardiac complications secondary to PMMA injection and subsequent cement leakage has increased with time...

From orthopedic to neurological disorders, stem cells are used as platforms to understand disease mechanisms and considered as novel and promising treatment options, especially when the valid therapeutic approaches are unavailable or ineffective. There are different stem cell types in the literature, however the spindle-shaped, colony forming and multilineage-differentiating cells, also known as mesenchymal stem cells (MSC) are very popular, as MSC can be isolated from different tissues with minimal ethical concerns and without tumor formations, which make them easily accessible and widely used in vitro and in vivo studies...

Research concerning bone substitutes is one of the most challenging fields in orthopedic research and has a high clinical relevance, especially since the currently available bone substitutes are limited in their osteostimulative capabilities. In-vitro models for the evaluation of the properties of bone substitutes allow the use of human mesenchymal stem cells (hMSC) seeded onto scaffolds, but suffer from the lack of a physiological environment for those cells. Most in-vivo models include the use of non-human MSC and are therefore lacking in clinical relevance...
