noninvasive tool that can aid in the evaluation of the entire spectrum of internal derangements of the knee. Although the cost varies considerably across the country, the average cost of knee MRI is on the order of several hundred to more than a thousand dollars. The noninvasiveness of MRI combined with its relatively low cost have led to its acceptance by the orthopaedic community, and MRI of ...

background hook plates are used to treat acromioclavicular joint dislocations. our study took into consideration the patients’ outcome following treatment with clavicular hook plates retained for more than five months. objectives our aim was to assess the response to treatment of acromioclavicular joint dislocation by clavicular hook plate when retained for more than five months. patients and m...

periodontal ligament is a thin layer of soft tissue that connects root of a tooth to the surrounding alveolar bone. these ligaments play an important role in initiating tooth movement when loads are applied to teeth with orthodontic appliances. the majority of such soft tissues exhibit as viscoelastic bodies or have a time-dependent behavior. due to the viscoelastic behavior of the periodontal ...

The problem of generating beams periodic internal waves in a viscous, exponentially stratified fluid by band oscillating along an inclined plane is considered the methods theory singular perturbations linear and weakly nonlinear approximations. complete solution to problem, which satisfies boundary conditions on emitting surface, constructed taking into account previously proposed classificatio...

The authors first reviewed the history of clinical application of artificial ligaments. Then, the status of clinical application of artificial ligaments was detailed. Some artificial ligaments possessed comparable efficacy to, and fewer postoperative complications than, allografts and autografts in ligament reconstruction, especially for the anterior cruciate ligament. At the end, the authors f...

introduction: nano-indentation has recently been employed as a powerful tool for determining the mechanical properties of biological tissues on nano and micro scales. a majority of soft biological tissues such as ligaments and tendons exhibit viscoelastic or time-dependent behaviors. the constitutive characterization of soft tissues is among very important subjects in clinical medicine and espe...

The adherence of the overlying tissues to the underlying structures in the face is maintained by the retaining ligaments. True retaining ligaments named orbital, zygomatic and mandibular ligaments are a series of fibrous bands that run from periosteum to the dermis. The tethering effect of true retaining ligaments must be released for achieving a satisfactory movement of facial skin and Superfi...

Wrist ligaments are crucial structures for the maintenance of carpal stability. They are classified into extrinsic ligaments, connecting the carpus with the forearm bones or distal radioulnar ligaments, and intrinsic ligaments, entirely situated within the carpus. Lesions of intrinsic and extrinsic ligaments of the wrist have been demonstrated to occur largely, mostly in patients with history o...

background many factors effect on management (surgical and nonsurgical) of adolescent idiopathic scoliosis (ais). objectives the purpose of this study was evaluation of the effects of generalized ligamentous laxity (gll) on surgical treatment of ais. materials and methods 72 patients with ais were studied between 2002 and 2009. 24 cases (33.4%) were placed in group a (normal) while 48 patients ...
