The Joint puts the leg in abduction and external rotation when the patient is susceptible to dislocation (during hip flexion), yet leaves the leg in a neutral position when the patient is not in danger of dislocation (while the hip is extended). Since ambulation of a postoperative hip patient involves a very small range of motion at the hip, the patient feels no uncomfortable abduction forces while ambulating.

When the patient is at extension the abduction angle can be set to zero (or if desired at any angle between 0 - 15 degrees.) As the patient flexes his hip, the joint moves the leg into abduction reaching 20 degrees abduction when the hip is flexed to 90 degrees. The patient’s leg is also externally rotated as he flexes.

Adjustment wedges allow the practitioner to set the abduction angle at extension anywhere from 0 - 15 degrees. Some practitioners may choose to set the “standing” angle of abduction to15 degrees at the initial fitting (meaning the joint will start at 15 degrees abduction at full hip extension and increase to 20 degrees at 90 degrees flexion). As the patient progresses the practitioner has the option to reduce the “standing” angle of abduction to lets say 5 degrees (meaning the joint will start at 5 degrees abduction at full hip extension and increase to 20 degrees at 90 degrees flexion) increasing the patient’s comfort during ambulation while maintaining abduction control of the hip in flexion.

The Genesis also has multiple flexion and extension stops to limit the range of motion of flexion and extension if desired.
The Genesis, representing the latest in hip joint technology, is a completely new approach in hip abduction bracing.
