Multiphysics Coupled Modeling of Coal Seam Fracture Stimulation Under Highly Pressurized Gas Impact Loading
3D gas-solid coupled symmetrical numerical model was developed on the basis of multiphysics finite element platform to study coal seam fracture stimulation under the high pressure gas impact loading generated by the highly pressurized multi-discharge carbon dioxide gas fracturing technique to improve pre gas drainage efficiency. The purposes of this study are to understand the natural and operational factors contribute to coal seam fracture stimulation and improvement of coal seam gas drainage efficiency and the interaction of these parameters.
Case Report: Severe Sequelae of Sleep Disorders
We report 2 cases of severe injuries in patients with sleep disorders. The first patient sustained multiple orthopedic traumas as sequelae of REM sleep behavior disorders (RBD). The second patient sustained a severe TBI as a result of restless
legs syndrome (RLS). To our knowledge, there are only 2 reported cases of severe orthopedic traumas (cervical spine
fractures) as a result of RBD and no reported cases of severe TBI from RLS.
An Unusual Case of Guide Wire Fracture during Percutaneous Peripheral Angioplasty
Guide wire fractures during coronary or peripheral angioplasty are very rare and Incidence of these complications are around 0.02 % [1]. The guide wire remnants can lead to complications, such as thrombosis, embolic phenomena and perforation [2].
Early Spondyloarthritis Presenting as Premenopausal Osteoporosis and Multiple Vertebral Fractures: A Case Report
We report a 30-year-old woman who presented during pregnancy with mechanical type backache due to non-traumatic multiple vertebral fractures. In-depth the assessment revealed multiple risk factors for osteoporosis, including adolescent steroid use for asthma, prolonged breastfeeding, and vitamin D deficiency. She also had persistently elevated inflammatory markers with radiological evidence of early inflammatory Sacro-ileitis. The rheumatoid factor and HLA B27 were negative. She was successfully managed with NSAIDS, zoledronic acid, and calcium supplementation. This is an example of early inflammatory arthritis in the background of multiple risk factors causing osteoporosis severe enough to cause fragility fractures. This signifies the importance of screening for multiple risk factors in pre-menopausal osteoporosis even in the presence of one or two identified risk factors.
Modified and Combined Lateral and Posterolateral Approach an Alternative Treatment to Tibial Plateau Fractures
The selection of a surgical approach for the treatment of tibia plateau fractures is an important decision. Approximately 7% of all tibia plateau fractures affect the posterolateral corner. Displaced posterolateral tibia plateau fractures require anatomic articular reduction and buttress plate fixation on the posterior aspect. These aims are difficult to reach through a lateral or anterolateral approach. The standard posterolateral approach with fibula osteotomy and release of the posterolateral corner is a traumatic procedure, which includes the risk of fragment denudation. Isolated posterior approaches do not allow sufficient visual control of fracture reduction, especially if the fracture is complex. Therefore, the aim of this case report was to present a surgical approach for posterolateral tibial plateau fractures that both protects the soft tissue and allows for good visual control of fracture reduction. The approach involves a lateral arthrotomy for visualizing the joint surface and a posterolateral approach for the fracture reduction and plate fixation, which are both achieved through one posterolateral skin incision. Using this approach, we achieved reduction of the articular surface and stable fixation in patients at the final follow-up visit. No complications and no loss of reduction were observed. Additionally, the new posterolateral approach permits direct visual exposure and facilitates the application of a buttress plate. This approach does not require fibular osteotomy, and fragments of the posterolateral corner do not have to be detached from the soft tissue network.
Displaced Fracture of the Proximal Humerus Causing Axillary Artery Injury and Brachial Plexus Palsy
Proximal humeral fractures account for approximately 5% of fractures seen in the emergency department. Despite this relatively high incidence only 15% of these fractures are displaced with an even smaller proportion being severely displaced enough to cause an axillary artery injury. We report a case of an elderly female patient who slipped and fell at home. She presented to our unit complaining of left shoulder pain and an inability to feel or move the involved limb. Imaging studies confirmed the presence of a severely displaced fracture of the proximal humerus and occlusion of the axillary artery. She was taken for open reduction and internal fixation of the proximal humerus followed by immediate axillary artery endovascular stenting.
Atypical Femur Fracture Nonunion in a Patient with Osteogenesis Imperfecta
Here, we present a 43-year-old male with osteogenesis imperfecta (OI) with previously placed intramedullary growing rods that sustained an atypical femur fracture (AFF) following long-term bisphosphonate use. He additionally experienced a non-traumatic ipsilateral femoral neck fracture that was successfully managed with operative stabilization. Despite previous reports following successful conservative management for AFF in patients with OI, nonunion developed requiring osteotomy and surgical stabilization.
Management-of-Postoperative-Pain-in-Patients-Undergoing-Surgery-for-Mandibular-Fracture
The mandible is one of the most frequently fractured bones in the facial skeleton. Postoperative pain control is an important outcome in assessing overall treatment success and patient satisfaction. However, few focused studies have reviewed protocols for postoperative pain management in patients with mandibular trauma. The aim of this study is to evaluate the protocol for the management of postoperative pain in patients undergoing surgery for a mandibular fracture in our department.
Research in Fracture Healing and Its Clinical Applications in the Veterinary Practice
Bone healing is a complex process consisting of multiple sequential phases needing the coordinated interaction of various cells, growth factors, cytokines and mechanical conditions. However, bone healing is one of the rare regenerative processes resulting in complete restoration of form and function. Fracture treatment aims towards a swift return to functional use of the injured limb. Therefore stabilization is a key requisite. In the veterinary clinic difficult fracture cases often require a unique stabilization by custom made external fixation. While this fixation technique harbors risk factors it offers a high flexibility essentially needed to successfully treat small animal fracture patients. Here we draw the connection between the up-to-date knowledge in bone healing and case reports of external fixation techniques from the small animal practice with respect to benefits and risk factors.
Fracture of the Hamate with Interposition of the Base of 5th Metacarpal, a Frequently Missed Injury
We report a case of hamate fracture in the coronal plane with interposition of the base of 5th metacarpal bone. This injury is frequently missed and may results in increasing rate of morbidity and mal-union. In this article, the approach to this type of injuries, the diagnostic modalities, and the management will be discussed with review of the literature.
Clavicle Fractures: Allman and Neer Classification
Clavicle fractures are common injuries in young adults and children, and diagnosis can often be made based on history and physical exam. Treatment decisions vary according to the fracture’s location and multiple classification schemes have been devised to describe fracture patterns. The Allman model is the most widely used, which Dr. Neer subsequently revised to further delineate distal clavicle patterns. This article will illustrate the anatomy of the clavicle, its attachments and clinically relevant injury patterns. It is imperative to accurately classify these injuries as clinical outcomes and management options vary according to their morphology.

Clinical Evaluation of 762 Single-Tooth, Locking-Taper Implants: A Prospective Study with 1- to 12-Years of Follow-Up
The aim of this study was to evaluate the survival rate, complications and marginal bone loss of single-tooth lockingtaper implants.
In Vitro Comparison of Margin Fracture Strength of E.MaxTM and EmpressTM Inlays
Ceramic restorations are appealing because of their esthetics, high hardness and wear resistance. They can replace a composite or amalgam restoration in teeth where buccal and lingual walls remain intact and where excessive isthmus width contraindicates the use of a direct posterior composite restoration. Recent clinical trials have shown that porcelain restorations with margins on the occlusal surface of a posterior tooth tend to fail due to fracture of the porcelain under biting forces.
