The implantation of the OGAP-OPL is performed in either a single surgery or over two stages depending on the patients existing conditions and suitability.
As no two osseointegration patients are identical, the surgical process will vary slightly from patient to patient depending on their condition and needs.
The first stage will generally involve:
The bone residuum is reshaped and any bone spurs are removed.
The bone canal is prepared using a specialised instrument. The internal component of the implant is press fitted into the bone canal securing early stability and future bone ingrowth.
If there is a neuroma causing nerve pain the nerves involved will be addressed surgically by excision of the painful neuroma and deep positioning of the residual nerve into the muscle group to minimise future nerve issues.
The stump is refashioned in a cosmetic manner and the wound is closed in layers.
A period of six to eight weeks takes place after the first stage to allow for osseointegration. This is then followed by the second stage.
Involved in the second stage surgery is:
If the surgery is performed in a single stage, all of the above will take place during the one procedure.
Partial weight-bearing and the fitting of the lower prosthesis can take place as early as a few days after the second surgery. This is done under careful supervision of the team. It is now that the rehabilitation stage and gait training can begin.
