Among poliomyelitis patients, cosmetic interests in correction of atrophic and hypertrophic calves have been increasing as orthopaedic technique to lenghten short legs has been recently developed. It will lead to address their problems of mental distress and avoidance of certain social activities. Until now, calf augmentation has been operated by the use of silicone gel implants. Capsule formation and dislocation, gel bleeding, and implant rupture are rare but unpleasant complications. A new implant of solid silicone in the anatomical shape of gastrocnemius muscle placed subfascially appears to overcome these problems. Circumference of hypertrophic calf cannot be diminished by liposuction, because it is caused by pure muscle hypertrophy. Using the gastrocnemius for muscle flaps in covering knee defects does not impair  the function of the patient's leg. Therefore, the resection of part of the hypertrophic gastrocnemius muscles is an effective method to achieve a visible reduction of the calves. The author describes three cases; simultaneous calf augmentation using solid silicone implants and calf reduction by muscle shaving for correction of asymmetric legs in poliomyelitis patients. This procedure is performed under general anesthesia and has no complications. All patients were satisfied with the results. None complained of lack of stability or insecurity in walking and all became active in social life or changed their dress habits.
