Background: Calf augmentation can be achieved by fat grafting, calf implants, or a combination of both methods (composite augmentation). For safety reasons, it is important to be aware of important calf anatomic features, specific physiologic considerations, and some health conditions that can hinder the outcome of these procedures.
Objectives: The aim of this study was to present our experience with performing composite calf augmentation, and to describe indications, surgical techniques and safety issues.
Methods: We retrospectively analyzed 63 patients who had undergone composite calf augmentation for cosmetic and reconstructive surgery in our practice. We reviewed group demographics, complications, and results, and identified all the pitfalls encountered in our cases. Additionally, dissection of the calf regions in fresh cadavers was performed to obtain more accurate anatomy. We also measured intracompartmental pressures before and after calf augmentation with implants in 6 cases to determine pressure changes.
Results: All cases received subfascial implant insertion and fat grafting as a delayed procedure. If there is a need for multiple implants, we recommend a staged procedure. Our study showed high muscle sensitivity to pressure increase after augmentation. Hence, from the standpoint of safety, we advocate subcutaneous fat grafting only. No patients developed compartment syndrome.
Conclusions: Composite calf augmentation surgery is safe and easy to reproduce, with a short recovery period and a low complication rate when done as a staged procedure and respecting specific anatomic and physiologic calf features.
