|Treatment of malunion by ORIF usually has a good outcome. Osteotomy can reduce deformity and relieve functional impairment, but this places the bone at risk of fracture. Minor degrees of malunion are common and may not have a significant effect on function or appearance.|
Bone grafting usually is a successful treatment for nonunion, especially in the long bones of the body. Electrical and electromagnetic bone growth stimulators continue to progress and are especially advantageous in management of infected nonunions and in situations where surgery is not advisable. Low-frequency ultrasound therapy may decrease fracture-healing time in lower extremity nonunions by as much as two months (Patel). Bone marrow injection into the site of nonunion may resolve the nonunion without need for further surgery (Patel).
