Tibial blood supply is bad, how does bone not grow treat

summary

Nonunion is a common orthopedic disease, what is the situation for tibial nonunion? The mechanical characteristics of the tibia are weight-bearing. The middle and lower tibial shaft fractures are prone to poor blood supply, delayed union or nonunion. Because of the thin coverage of soft tissue in anterior tibia, skin necrosis and bone exposure are easy to occur. Our experience is as follows:

Tibial blood supply is bad, how does bone not grow treat

First, the causes of failure of plate fixation include too short plate, screw loosening, fracture after fixation with ordinary plate, and screw driving into fracture line. The indication, type of plate (material, length, thickness) and normal operation method should be selected strictly according to the principle of plate fixation.

Second, repeated stripping of periosteal plate fixation will aggravate the damage of blood supply. If the first plate fixation failed, the second plate fixation should not be the first choice.

Third, bone marrow stromal cells have the potential to differentiate into different cell lines. They can differentiate into osteoblasts when cultured in vitro and implanted in vivo. They can stimulate other cells in the recipient area to transform into osteoblasts and chondrocytes, and have the ability to synthesize bone matrix.

matters needing attention

Our method ensures early stability after internal fixation, bone graft replenishes the matrix needed for osteogenesis, bone growth factor and bone marrow cell implantation can differentiate into callus tissue, and effectively promote the healing of nonunion.
