The sartorius is an external rotator that is thought to be particularly active when the hip is flexed or abducted such as in a passé or front attitude. See Figure 8. The adductor muscles on the inner thigh may contribute to external rotation when the femur is in extension and is already ...
Being a ball-and-socket joint, the hip joint permits movements in three degrees of freedom:flexion, extension, abduction, adduction, external rotation, internal rotation and circumduction. How long do you stay in the hospital with a broken femur? Treatment methods included intramedullary nailing, o...
Mechanisms of Dislocation Dislocation occurs when forces acting over the implant in a detrimental direction reach amplitudes that overcome those keeping it intact. It usually takes place as a consequence of unintended external forces that act on a limb placed in an unfavorable position. However, it ...
However our model indicated that it is possible to achieve reduction of Grade 4 dislocation by hyperflexion and the resultant external rotation.Victor HuayamaveChristopher RoseSheila SerraBrendan JonesEduardo DivoFaissal MoslehyAlain J. KassabCharles T. Price...
The described modification may further minimize the risk of dislocation following hip arthroplasty, as the superior band of Bigelow's ligament is an additional checkrein to internal and external rotation. This repair provides a secondary intraoperative assessment of leg length and femoral offset to ...
A key factor for a good clinical outcome is to obtain a correct position with a neutral dorsi-flexion of the foot, an external rotation of 5110° and 5° of valgus deformity of the hindfoot. Contraindication are patient with a low compliance and all the cases in which there were ...
a collar may be included between the ball and a portion of the femur. The anchoring part is provided with external threads that are adapted to tap themselves into the femur. The transition part is coupled to the anchoring part by a guide pin and securing screw. The ball is adapted to be...
Through an anatomically designed hip/groin wrap covering most of the thigh and pelvis up to the iliac crest, the GRS simultaneously delivers both adjustable continuous-flow cryotherapy and intermittent compression through a portable control unit filled with ice and water. The machine has four pressure...

Flexion-extension of 15 to +30 degrees was applied to the head and internal-external rotation of +/ 10 degrees was applied to the cup, components were mounted anatomically. The lubricant was 25% (v/v) calf serum supplemented with 0.03% (w/v) sodium azide. Wear was assessed gravimetric...
