Introduction: Anterior cruciate ligament (ACL) reconstruction is one of the most widely performed orthopaedic procedures in developed counties. Reconstruction using autograft soft tissue such as hamstring tendon has been the preferred choice by many for its superior strength and less donor-site morbidity over the bone-tendon-bone graft. Fixation of soft tissue graft, however, has been less than...

Background: Anterior cruciate ligament injury is a common which occurs in sports with an annual incidence of 68.6% per 100,000 population. Anatomic arthroscopic reconstruction remains the main stay treatment ACL injury. Fixation graft classified as direct and indirect. To compare stability knee joint, complications anterior by aperture interference screw fixation versus suspensory device femur....

Displaced fractures of the lateral end of the clavicle in young patients have a high incidence of nonunion and a poor functional outcome after conservative management. Operative treatment is therefore usually recommended. However, current techniques may be associated with complications which require removal of the fixation device. We have evaluated the functional and radiological outcomes using...

BACKGROUND No definite consensus has been reached regarding the optimal technique for graft fixation to the femur in an anterior cruciate ligament reconstruction. The purpose of this study was to evaluate the mechanical strength of two cortical suspension devices which were the TightRope (TR), a new adjustable-length loop device, and the EndoButton (EB), a well-established fixed-length loop dev...

Treatment options for distal biceps tendon ruptures include nonoperative and operative approaches. Candidates for conservative nonoperative management include elderly low-demand patients, those in whom surgery is contraindicated because of medical comorbidities, and those who are unable to adhere to the strict postoperative rehabilitation regimen. Data have clearly shown the superiority of oper...

In a two-centre study, 164 patients with unilateral instability of the anterior cruciate ligament were prospectively randomised to arthroscopic reconstruction with either a patellar tendon graft using interference screw fixation or a quadruple semitendinosus graft using an endobutton fixation technique. The same postoperative rehabilitation protocol was used for all patients and follow-up at a ...

in this paper, for the first time we have studied theoretically the effect of exchange-correlation holes around electrons in gaalas/gaas/gaalas nanostructure on the temperature-dependent dynamic dielectric function of two-dimensional electron gas by employing random phase, stls and hubbard approximations. also, we have investigated another interesting system which is coupled quantum wells struc...

in this paper, quadratic rules for obtaining approximate solution of definite integrals as well as single and double integrals using spline quasi-interpolants will be illustrated. the method is applied to a few test examples to illustrate the accuracy and the implementation of the method
