The ideal management of the dislocated knee remains controversial. These injuries often can be elusive; a significant number of dislocated knees spontaneously reduce and appear relatively benign on routine radiographs. A high index of suspicion, based on the mechanism of injury, soft-tissue assessment of the limb, and the level of knee instability should alert the physician to the possibility o...

Patellar instabilities are the most common knee pathologies during growth. Congenital dislocations are rare. Extensive, early soft tissue releases relocate the extensor mechanism and may enable normal development of the femoro-patellar anatomy.Conservative management is the preferred strategy after a 'first-time' traumatic dislocation. In cases with concomitant anatomical predisposing factors s...

introduction the abducent nucleus is located in the upper part of the rhomboid fossa beneath the fourth ventricle in the caudal portion of the pons. the abducent nerve courses from its nucleus, to innervate the lateral rectus muscle. this nerve has the longest subarachnoid course of all the cranial nerves, it is the cranial nerve most vulnerable to trauma. it has been reported that 1% to 2.7% o...

Introduction The bony insertion of the anterior cruciate ligament (ACL) is comprised of four distinct zones: ligamentous tissue, noncalcified fibrocartilage, calcified fibrocartilage, and bone. This “enthesis” is responsible for effectively transmitting the forces from the elastic ligament to the stiff bone. Despite its well organized structure, the enthesis has limited vascularity and thereby ...

Instability of the patella is a common cause of knee pain and dysfunction in pediatric and adolescent patients and can be due to several factors. Although some patients will recall a specific traumatic event others may not, requiring the diagnosis to be made on the basis of physical examination and imaging. Congenital dislocation and connective tissue disorders should also be considered, even i...

Posterior cruciate ligament (PCL) injuries represent a minority of isolated ligamentous injuries to the knee. However the sequelae of these injuries can have a significant negative impact on function leading to instability, pain, and arthritis. A thorough understanding of the anatomy, mechanism of injury, and, pathophysiological changes that can occur with impaired PCL function can help the cli...

The posterior cruciate ligament (PCL) is the largest and strongest ligament in the human knee, and the primary posterior stabilizer. Recent anatomy and biomechanical studies have provided an improved understanding of PCL function. PCL injuries are typically combined with other ligamentous, meniscal and chondral injuries. Stress radiography has become an important and validated objective measure...

In this retrospective study, we assessed the outcome in 99 patients who underwent reconstruction of the lateral ligaments of the ankle for chronic anterolateral instability with a minimum follow-up of 15 years. Two techniques were compared: 54 patients had an anatomical reconstruction (AR group) and 45 had an Evans tenodesis (ET group). They were followed up for 19.9+/-3.6 years and 21.8+/-4.6 ...

Simple chronic instability of the elbow joint is one urgent problems in modern traumatology due to fact that standard tactics managing patients with traumatic injuries dislocation, which amounts its elimination, immobilization upper limb and subsequent development movements joint, most often does not take into account damage specific soft tissue structures. With untimely treatment for qualified...
