BACKGROUND The knee joint is vulnerable to various injuries and degenerative conditions, potentially leading to functional instability. Usual treatments involve knee orthoses to support the joint. However, the level of mechanical action of these devices remains controversial despite high prescription and demand. METHODS The mechanical ability of three commercial hinged knee braces and one sle...

She will succeed Gert Steyn, the new SAMA General Manager, who over the past two years, both before and during his current tenure, revitalised HMPG, the country's leading medical publishing group, by taking it from a net loss-making enterprise to a thriving, financially sound, technologically relevant and income-diverse platform. Kikaya will use this springboard to apply her unique combination ...

The structures in the posterolateral corner of the knee, which stabilize the joint, are often involved in injuries to the posterior cruciate ligament. Familiar structures include the anterior cruciate ligament, posterior cruciate ligament, tibial collateral ligament, and menisci. Less familiar are the structures of the posterolateral corner, the most important of which are the fibular collatera...

Shamir proposed the setbase approach as a means of improving security and privacy of the traditional biometric system. In this paper, we propose privacy-preserving drawer size standards for the biometric setbase. The proposal incorporates database privacy metrics such as k-anonymity and l-diversity into the definition of privacy-preserving drawer size standard for the biometric setbase. We also...

Pre-operative clinical examination revealed no neurovascular deficit, but was limited due to significant pain and patient reluctance to participate in range of motion. Radiographs showed an intraarticular fracture of the posterior aspect of the right tibial spine with the dominant fragment displaced approximately 1 cm posteriorly in the joint space. Computed Tomography (CT) verified a 1 cm frag...

BACKGROUND We have already discovered 23 patients during the work of the outpatient department and operations whose unstable signs on the posterolateral ankle. The anterior drawer test demonstrated normal during the physical examinations while the spaces of the posterior tibiotalar joints increased in stress X-ray plain films. ATFL intact and posterolateral ligaments lax were found during opera...

Many methods of reconstruction for ACL deficiency have been described, but little is known about their biomechanical properties. We examined extra-articular (EA), intraarticular (IA) and combined (EA + IA) reconstructions in ten cadaver knees after the ACL had been ruptured by the performance ofa rapid anteriordrawer movement. Stabifity at each stage before and after rupture and reconstruction ...

OBJECTIVES Injury to the lateral ligament complex of the ankle is one of the most common sports-related injury. Usually lateral ankle evolves with excellent clinical recovery with non surgical treatment, however, near about 30% develop a lateral chronic instability sequela. Several open and arthroscopic surgical techniques have been described to treat this medical condition. MATERIAL AND METH...
