Osteosynthesis of the Future

Second quarter of 21st century, we are only at the beginning of modernity.

Since almost hundred years orthopedists are practicing what we call osteosynthesis for fractures of bone.

At the beginning OS-material was out of steel, which was rusting, then rust-free, and nowadays out of titan.

In lower extremities those still break on and off.

After consolidation of bone, they need a second operation to take them off.

I wonder, with modern techniques it should not be difficult to produce OS-material out of bone, which implies a collagen matrix with deposition of calcium pyrophosphate crystals on it.

Such ones need to be thicker and sturdier for legs.

Advantage would be, they will be incorporated in fractured bone and will not need a second procedure for removal.

Screws out of cortical bone could be manufactured in a similar way.

There exist 3-D printers able to construct a fine matrix out of synthetic material- so why not out of natural one like bone?

Without having recourse to complex techniques, you can produce a simple natural OS out of a splinter of cortical bone, inserted in the medullary space.

This is readily feasible for upper extremity, and the splinter can be autologous, or allograft of a compatible donor.

In future, I think similar procedures could replace metal hip prostheses.

The 3-D printer would produce a new hip joint out of bone, which would be placed with a large basis on the intertrochanteric region.

The lower end would have a pointed apex, to be inserted into the femoral medullary cavity.

With such interventions immobilization should be adapted to material and type of procedure.

For cancellous bone only 2 weeks are needed for consolidation with collagen, while for cortical one, this value is highly variable, reaching 2 months for the femora.

Gentle movement pondering resistance, at first without, then introducing progressively such, would stimulate vessel and bone marrow ingrowth.
