Hallux Valgus (bunion): innovation in surgical techniques

The PBS Procedure to treat bunions

A step-by-step procedure, which accompanies the patients throughout and guides them in their choice of the best solution (THERAPY or SURGERY) according to their condition and their individual physical and biological characteristics.

The Initial Consultation

The PBS procedure begins with an initial consultation to establish the extent of the problem and to decide whether the patient can be treated with non-surgical treatment (e.g. orthotics) or whether surgery is necessary.

Preparing for surgery and hospitalisation

If the conservative therapy is not possible, the patient is put on the waiting list for surgery in the clinic and with their chosen doctor.


Surgery with PBS instruments without fixation devices (pins, wires ...). Assessment of alignment is followed by the dressing and specific PBS bandaging.


Personalised plan of aftercare and immediate walking.


Depending on the type of treatment you have received, you will return for a check-up after 15/20 days. You will be given personalised instructions with exercise and medication, if necessary, for your recovery period.

X-Ray Check up

45 days after surgery, your surgeon will give you a routine check-up with X-rays to verify the progress of calcification, consolidation and alignment of the bones in your foot.

  • As we do not use pins or metal wires, the foot is left free, so it can immediately begin to settle naturally by walking, which you will be allowed to do from the start

  • Bunion correction is never an aesthetic choice and the decision to operate is taken when pain limits walking.

  • We do not operate beautiful or ugly feet, only painful feet

  • Bones know how to heal themselves from fractures, but not from pins

Conditions of the forefoot treatable with keyhole surgery

The PBS Group is specialised in the treatment of the lower limbs. The principal conditions of the forefoot can be operated under keyhole surgery, as modified by Dr Bianchi. Other conditions still need to be treated in more “traditional” ways.
