In skeletally mature adolescents and in adults, an osteotomy is the treatment to straighten the leg. X-rays are used to determine the location and magnitude of the deformity. In most cases, the tibia is treated, but there are situations when the femur or both femur and tibia are treated. When there is moderate deformity, the osteotomy is typically stabilized with internal fixation a plate or rod inserted into the leg. When the malalignment is more severe, gradual realignment of the limb through the osteotomy is done with an external fixator.
With external fixators, pins are inserted into the bone and protrude out of the body to attach to an external stabilizing structure.
In some cases, the underlying bowleg condition causes one leg to be shorter than the other. This can also be corrected, using limb lengthening surgery.
