Minimally invasive surgery

The recent development of less invasive surgical techniques, minimally invasive or percutaneous, allows us to effectively treat a variety of foot and ankle pathologies. PD Dr Assal, as a foot, ankle and leg surgeon has contributed to refining these techniques. His team offers this type of procedure if the clinical examination and X-rays suggest it is a safe and appropriate solution.

Deformity of big toe and lesser toes

Highly effective for certain foot deformities such as bunions minimally invasive foot surgery consists of a 2–3 cm incision that leaves practically no scar. Nevertheless, this surgery is tricky and requires extensive experience for foot balance to be restored perfectly.


Achilles tendon repair

Dr Assal invented the minimally invasive Achillon® method, a surgical technique used to repair acute Achilles tendon ruptures. In light of its outstanding success rate, this technique is now used worldwide.


Tendon transfer

Minimally invasive foot or ankle surgery is also performed when a dynamic foot deformity or a neurological disease requires that a tendon be transferred to another insertion point to restore the lost motion.



Certain fractures are better treated using less invasive surgical methods, such as those in the lower leg, calcaneus or mid-foot.
