The term HKAFO is an acronym that stands for hip-knee-ankle-foot-orthosis and describes the part of the body that this device encompasses. This device is a basically a KAFO with the addition of a hip joint and pelvic section. (Please review KAFO information).
The addition of the hip joint and pelvic section provide control to selected hip motions. These selected motions about the hip are front to back, side to side, and rotation. One reason the hip section is added to a KAFO is to reduce or minimize the risk of the hip moving out of proper position or dislocating. Another common reason is to stabilize the hip and lower spine in cases where the patient is weak or paralyzed.
