It is a semi-rigid girdle with a modular system that contributes to the treatment of a large number of back injuries. It is made of a highly resistant elastic fabric that adapts to the body. It is indicated for moderate dorsal and lumbalgias thanks to its modular system. This modular system is made up of three elements that are purchased independently. These are: the back support, the girdle itself and the thermoplastic plate. The back support module is prescribed by the doctor in case of back pain. The thermoplastic module must be individually adapted by an orthoprosthetist and fits snugly to the back. It is breathable and comfortable. It is recommended to follow the instructions of the specialist. Prim adapts to the needs of the patient as it allows to add or remove elements.. *For hygiene reasons, we do not accept returns for this product after it has been opened.
