Syringic acid (SA), a phenolic acid, has been used in Chinese and Indian medicine for treating diabetes but its role in osteogenesis has not yet been investigated. In the present study, at the molecular and cellular levels, we evaluated the effects of SA on osteoblast differentiation. At the cellular level, there was increased alkaline phosphatase (ALP) activity and calcium deposition by SA treatment in mouse mesenchymal stem cells (mMSCs). At the molecular level, SA treatment of these cells stimulated expression of Runx2, a bone transcription factor, and of osteoblast differentiation marker genes such as ALP, type I collagen, and osteocalcin...

Sheep is a relevant large animal model that is frequently used to test innovative tissue engineering (TE) approaches especially for bone reconstruction. Mesenchymal stem cells (MSCs) are used in TE applications because they represent key component of adult tissue repair. Importantly, MSCs from different species show similar characteristics, which facilitated their application in translational studies using animal models. Nowadays, many researches are focusing on the use of ovine mesenchymal stem cells (oMSCs) in orthopedic preclinical settings for regenerative medicine purposes...

The orthopedic field has experienced several major practice-changing pivotal shifts in the past several decades, such as the invention and application of the arthroscope or the implementation and advancement of joint arthroplasties. Most of these previous breakthroughs have focused on surgical techniques and devices. However, the next major advance in the field is likely to be related to biologic treatments. Although still in its early stage of development, orthopedic regenerative medicine, including cellular therapies, represents a great opportunity, since we are only beginning to understand their biological potential...

Recovering of significant skeletal defects could be partially abortive due to the perturbations that affect the regenerative process when defects reach a critical size, thus resulting in a non-healed bone. The current standard treatments include allografting, autografting, and other bone implant techniques. However, although they are commonly used in orthopedic surgery, these treatments have some limitations concerning their costs and their side effects such as potential infections or malunions. On this account, the need for suitable constructs to fill the gap in wide fractures is still urgent...

PURPOSE: Although they are considered the 'gold standard' of evidence-based medicine, randomized controlled trials are still a rarity in orthopedic surgery. In the management of patients with multiple trauma, there is a current trend toward 'damage control orthopedics', but to date, there is no proof of the superiority of this concept in terms of evidence-based medicine. The purpose of this article is to present unexpected difficulties we encountered in successfully completing our randomized controlled trial and to discuss the problematic differences between theoretically planning a trial and real-life practical experience of implementing the plan, with attention to published strategies...

Dislocation of the major joints of the lower extremities--hip, knee, and ankle--can occur due to motor-vehicle crashes, falls, and sports injuries. Hip dislocations are the most common, and they require emergent management to prevent avascular necrosis of the femoral head. Knee dislocations are uncommon but potentially dangerous injuries that can result in amputation due to the potential for missed secondary injury, especially if they are reduced spontaneously. Isolated ankle dislocations are relatively rare, as most ankle dislocations involve an associated fracture...

With the increase of elderly population, orthopaedic surgeons need to deal with the diseases related to aging, such as joint disorders and fragility fractures. The number of total joint replacements, for example, is two times more than it was 10 years ago. With these backgrounds, the Japanese Orthopaedic Association (JOA) has proposed the concept of locomotive syndrome; conditions under which the elderly have been receiving care services due to problems of the locomotive organs. To prevent geriatric or disuse syndrome, JOA is currently providing the care‒prevention programs such as the loco-check and loco-training...

REVIEW
D M Rouleau
The design of clinical studies in orthopedic traumatology is challenging in several respects. In this era of evidence-based medicine, the pressure is high to choose our treatments solely based on randomized controlled studies. This type of study, when well-constructed, makes it possible to discern the best treatment for a specific fracture in a given group of patients and in connection with a specific outcome. Randomized controlled trials require a lot of resources and are not designed to answer all research questions...

There is inevitable need for data regarding anthropometric measurements of each community's population. These anthropometric data have various applications, including health assessment, industrial designing, plastic & orthopedic surgery, nutritional studies, anatomical studies and forensic medicine investigations. Anthropometric parameters vary from race to race throughout the world, hence providing an anthropometric profile model of residents of different geographic regions seems to be necessary. To our knowledge, there is no report of bone parameters of the Iranian population...
