Malocclusion in Adults: Biomechanical Considerations
cents has always relied on growth modification. The majority of treatment modalities, such as functional appliances, are directed at stopping or redirecting maxillary growth and simultaneously stimulating mandibular growth.1-3 On the other hand, in adult patients with severe Class II malocclusions, generally involving extremely deficient mandibles, orthognathic surgery is often the only possibl...
متن کاملShoulder impingement: biomechanical considerations in rehabilitation.
Shoulder impingement is a common condition presumed to contribute to rotator cuff disease. Impingement can occur externally with the coracoacromial arch or internally with the glenoid rim. Normal scapulothoracic motions that occur during arm elevation include upward rotation, posterior tilting, and either internal or external rotation. These scapulothoracic motions and positions are the result ...
متن کاملFemoroacetabular impingement: biomechanical and dynamic considerations.
Femoroacetabular impingement (F.A.I.) is a pathologic process caused by an abnormal shape of the acetabulum, of the femoral head, or both. F.A.I., often referred to as idiopathic, may be secondary to slipped capital femoral epiphysis, congenital hypoplasia of the femur, Legg-Calvé Perthes disease, post-traumatic mal-union and protrusio acetabuli.

متن کاملBiomechanical Considerations in the Competitive Swimmer’s Shoulder
CONTEXT Competitive swimming has become an increasingly popular sport in the United States. In 2007, more than 250 000 competitive swimmers were registered with USA Swimming, the national governing body. The average competitive swimmer swims approximately 60 000 to 80 000 m per week. With a typical count of 8 to 10 strokes per 25-m lap, each shoulder performs 30 000 rotations each week. This pl...
متن کاملBiomechanical Considerations for Total Knee Arthroplasty
Total knee replacement (TKR) is now recognized as a viable surgical option for managing dogs with severe to end-stage stifle joint osteoarthritis. The goal of this presentation is to briefly review the biomechanics of the normal stifle joint and to describe how this information has been used to guide the design and manufacture of contemporary TKR implants. The influence of implant design, surgi...
