Abstract/OtherAbstract:
This study outlines a relationship between joint volume, positioning, and intracapsular pressure in a healthy hip. After measuring the native intracapsular pressure in 12 porcine specimens, each joint was injected with radio-opaque-colored saline as pressures were measured. At 20 mmHg, the hip was placed in its position of ease and then in differing positions while pressures were recorded. Position significantly altered pressures, with the lowest values in neutral and the highest in hyperextension (P<0.001). Extreme hip positions may be detrimental because of high pressures created within the joint, possibly explaining complications associated with some hip diagnostic and treatment methods.
