Twenty-six patients who had tibial lengthening procedures (Anderson) are reviewed.
The rate of union may be assessed at an early stage (eight weeks), and early indications for bone-grafting may be realized at that time.
Lengthening of over five centimeters is associated with an increased rate of complications.
Angulation at the operative site may occur early or late during the treatment routine, and satisfactory bone stability should be present before the lengthening apparatus is removed.
Angulation which develops during the lengthening treatment tends to persist.
Foot deformities appear to result from preoperative or postoperative muscle imbalance.
Ischemia is suggested as a cause for the appearance of muscle weakness in some patients.
