[Augmentation mammaplasty using injected polyacrylamide hydrogel: Report of a recent case and literature review]

Polyacrylamide hydrogel (PAAG) is a filler that has been strictly prohibited in France for many years. It first appeared on the market in 1980, used as an injectable for breast and facial augmentation, mainly in Asia and Eastern Europe. Like many other materials, it has shown unfavourable results and complications due to a foreign body reaction. It was banned in 2006, but continues to be injected illegally. With the influx of migrants, we are faced with the problem of how to manage complications, which can occur more than a decade later. We report our experience of a recent case in our department that required complete removal of the product and iterative lipofilling, with a result that remains sub-optimal, and we systematically review the literature.

[Rotationplasty as an alternative to amputation]

Rotationplasty can be used as an alternative to amputation when conservative treatment is not possible, for example in malignant tumours of the knee. The principle of the operation is to rotate the lower leg through 180 ° after resection of the distal femur and in this way the ankle joint replaces the knee joint. This surgical technique, although complex, allows satisfactory carcinological resection with a functional outcome superior to amputation above the knee as well as a better quality-of-life. Patients do not develop phantom pain, neuroma or stump discomfort because it is not an amputation. In addition, they can actively control their knee and having proprioception and normal contact with the ground. This results in a coordinated, harmonious and elegant gait pattern similar to the normal population. Patients are more efficient in their activities of everyday life and sports. The major disadvantage is the particular aesthetic aspect and the psychological acceptance.
