Osteochondritis dissecans (OCD) is a common joint disorder in knee, ankle and elbow, however it can be rarely found in glenohumeral joint. In this study, we report an asymptomatic case of humeral head OCD, which was detected incidentally following a trauma. X-rays showed an area of lucency around an oval bony fragment measuring about 1 cm on the superior aspect of the humeral head. However, ...

The kinematics and dynamics of two industrial cooperating robots are presented in this paper. The NOC (natural orthogonal complement) method is used to derive the dynamical equations for the motion of two cooperating robots. The joint torques of the two robots are determined based on the optimization techniques in order to obtain unique solution for joint torques. To this end, minimizing the cr...

Introduction: Frozen shoulder syndrome (FSS) is a common shoulder disease that causes pain and has progressive loss of shoulder motion. Codman's pendulum exercises are commonly prescribed after a shoulder injury to provide early joint mobilization, increase the flow of nutrients into the joint space, and decrease pain. This study aimed to compare the effect of Cadman's exercises and scapular rh...

  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 recons...

Background: One of the most important issues for patients with osteoarthritis is reducing pain and returning them to normal life. In addition to losing weight and improving daily activities, pain management treatments may be needed. One of these treatments is the injection of hyaluronic acid gel into the knee joint, which has been studied in this study. Methods: In this stud...

introduction osteochondritis is a joint condition in which bone underneath the cartilage of a joint destroys due to lack of blood flow. then bone and cartilage can break, causing pain and sometimes affecting joint motion and skin around the involved joint might be swollen and tender. osteochondritis occurs most commonly in the knee, but also occurs in elbows, ankles and other joints. decreased ...
