Correction of Severely Asymmetric Calf using Latissimus Dorsi Musculocutaneous Free Flap and Customized Silicone Implant

Calves can be easily seen in daily life and are an important part of the body contour. Asymmetric calves can develop from unbalanced distribution and deposition of fat and muscles between the legs. Calf asymmetry may be due to congenital factors, disease (e.g., poliomyelitis, cerebral palsy, or infection), spinal cord injury, or the effects of surgical treatment and may have severe adverse psychological and social implications. Generally, an asymmetric calf is diagnosed when the difference of the longest circumference between both calves is more than 2 cm. Several surgical methods have been introduced for the correction of an asymmetric calf. Implant insertion or fat injection is used to augment a hypotrophic calf. Selective neurectomy, liposuction, muscle resection, radiofrequency, and botulinum toxin injection are used to treat a hypertrophic calf. With the development of microsurgery, the authors planned to use a latissimus dorsi musculocutaneous free flap (LDMC free flap) with silicone implant to add calf volume to obtain natural calf contour. The authors present the first successful case of correction of a severely asymmetric calf using an LDMC free flap and customized silicone implant.
