Role of auto-omental graft on the fracture healing after periosteum destruction : radiographic study

الملخص EN

The aim of this study is to evaluate the effect of the auto-omental graft on the fracture healing after destruction of the periosteum around the fracture site in rabbits.

Eight mature healthy rabbits of local breed were employed to performed transverse fracture in the mid shift of the femoral bone, under general anesthesia and highly aseptic technique, then destruction of the periosteum was done about 1 cm away from each end of the fragments bone.

The immobilization by intramedulary pinning, then the animals were divided into two equal group.

The control group was left to follow the healing process, while in the treatment group the auto- omental graft was used to cover the fracture site.

This graft was taken from the laparotomy of the left side and weekly radiographic examination performed for 10 weeks.

The result is revealed that the omental graft play an important role in promote the fracture healing which was evident during the early new bone formation at the end of the second week compare to the control group which the sign of the callus formation was obvious lately at the end of the third week.

The nature of the callus formation of the treatment group was limited to the fracture site and quickly cross the fracture site .While in the control group the new bone formation was heavy unlimited and need 8-9 week to bridge the fracture fragments.

The omental graft play role in starting the remodeling phase, by decreasing the amount of the callus formation, with the signs of increase of the callus density, and marked of incorporation of the callus formation with the cortical bone.
