Conventional surgery

Certain conditions, such as misaligned bones and joints, deformities, arthritis and fractures, require a more extensive procedure than simple percutaneous surgery. Whether for foot, ankle or leg surgery, the surgeons at the Centre ASSAL have extensive experience in conventional surgical techniques, which means they can perform even the most delicate procedures to help you quickly regain your mobility and resume your activities (walking, sports, etc.).


Depending on the fracture’s severity, an open surgical procedure may be the best way to restore the broken bone to its initial shape. Open surgery is performed when the other options are not feasible.



Osteotomy is one of the most common foot and ankle operations. It is conducted as an open surgical procedure when a specific deformity has developed because of poor bone or joint alignment (bunion, toe deformity, metatarsalgia, flat feet, etc.). This foot and ankle surgery consists of making cuts in the bone to restore its natural alignment.



Fusion or arthrodesis is another common procedure performed as open surgery when a joint is severely damaged or has become significantly deformed (bunion, hallux rigidus, Lisfranc injury, flat feet, heel misalignment, etc.). This foot and ankle procedure consists in removing the damaged cartilage between adjacent bones and then joining these bones with screws and/or plates.


Ankle replacement

When chronic inflammation of the ankle joint arises as a result of the gradual destruction of the cartilage, total ankle replacement (TAR) is performed through an open surgical procedure. A true leader in this field, Centre ASSAL has nearly 20 years of experience with TAR. Working in collaboration with Prof. Xavier Crevoisier of the CHUV, PD Dr Assal has performed more than 400 TAR procedures and has revised nearly 500 prostheses.
