Trevor disease or dysplasia epiphysealis hemimelica (DEH) is an extremely rare condition with incidence of about 1:1,000,000. Male to female ratio of reporting case is 3:1, and usually diagnosed between two and eight years old. It usually affects the medial portion of the joint, but lateral involvement is not uncommon. Hip-joint was affected in less than 4% of existing cases in the literature. ...

simultaneous mid third clavicle fracture and acromioclavicular joint dislocation is a rare combination injury, as a result of high-energy trauma. we report a patient with a middle third clavicle fracture and ipsilateral grade three-acromioclavicular joint dislocation, which is a rare combination. the patient wanted to get back to work as soon as possible, so the fracture was fixed with reconstr...

In this work, the interaction between the semi-circular space and the neighboring joint with and without the presence of rock bolts was investigated using the particle flow code (PFC) approach. For this purpose, firstly, the calibration of PFC was performed using both the Brazilian experimental test and the uniaxial compression test. Secondly, a numerical model with the dimension of 100 m...

Introduction: It has been approved that in most tissues NO production increases during acute inflammation and Angiotensin II has a role in production of reactive oxygen species (ROS). As regulation of joint blood flow (JBF) is important in this situation, this study was performed to investigate the interaction of local Ang II and ROS production and the modulatory role of NO on regulation of JBF...

Providing suitable analgesia following diagnostic and therapeutic arthroscopic surgeries, that areconsidered to cause some degree of postoperative pain, is a necessity in equine practice. The aim of thepresent study was to evaluate the equine synovial fluid biochemical and cytological changes as well asclinical assessments of the joint following intra-articular administration of ketamine. Six a...

a parametrik investigation was conducted to study the non-linear behavior of precast and cast-in-place reinforced concrete beam-column connections subjected to tabas seismic forces (1979). the behavior of these types of connections in a four stories structure with respect to strength, ductility , stiffness, and bond deterioration at the joint core are presented and discussed. calculation result...

Background:  The glenohumeral joint becomes dislocated more than any other major joint because it maintains a wide range of motion and its stability is inherently weak. The most common complication following acute initial shoulder dislocation is recurrent dislocation or chronic instability. Imbalance of strength and range of motion in individuals with anterior dislocation can be a contributing ...
