The surgical implantation technique involves two separate surgical procedures, called Step 1 and Step 2, with in-between a minimum of 60 days time to allow the healing of surgical scars, soft tissues and the initial osseointegration of the intramedullary implant.

 

  • STEP 1: Skin, subcutaneous tissue and fascia are incised until the bone plane is reached and exposed. Soft tissues and redundant skin are removed reducing the distance between the bone and the skin. The muscle groups are reorganized to have an active function in the mobility of the restored limb. The osteotomy is then performed as decided in the preoperative planning and the bone spurs are removed. The intramedullary canal is sequentially reamed and tapped on a guidewire under ampliscopic control. The implant is subsequently screwed into the housing created within the medullary canal. Finally, the soft tissue suture is applied to cover the distal bone stump by performing distal myoplasty.

 

  • STEP 2: an incision is made on the previous scar to find the implanted intramedullary components inside. Subsequently, a circular cutaneous stoma is formed which is sutured around the distal part of the stump, then the prosthetic component of connection between the osseointegrated implant and the external prosthesis is inserted.
