Bone Grafting

Repair of iliac bone defects. Treatment of diseases: bone defects Indication Bone margin bone defect. Preoperative preparation You should fast for eight hours before surgery, and you can drink half a cup or less of water (barley tea) three hours before surgery, but you cannot drink milk or orange juice. Prohibition of alcohol should be done the day before surgery, and excessive weight loss, taking diuretics, taking aspirin, and excessive smoking before surgery can have adverse effects on surgery. Surgical procedure The method of cutting the humerus: the buttocks on the side of the surgery are slightly elevated. The ankle skin is moved to one side, and the anterior superior iliac crest is used as a skin incision to separate the subcutaneous tissue and expose the humerus. An "H"-shaped periosteal incision was made to separate the periosteum from the periosteal stripping ions to expose the desired range of bone. First use the osteotome to open the sides of the iliac crest vertically, then open the bone in the central part, remove the inner bone piece, bone wax to stop bleeding. The bone pieces were wrapped with saline gauze for use. Suture the periosteum and skin. The drainage strip was placed within 48 hours, and the dressing was partially compressed. The external pressure of the dressing was 2 to 3 days in a sandbag. Limb bone graft 1. Make a skin incision parallel to the margin of the defect. The soft tissue is fully released to the periphery, and the upper edge is reached. 2. Cut the periosteum at the lower edge of the defect and peel it upward to the gingival margin to fully expose the defect area. 3. According to the shape, size and depth of the defect range, the following methods can be used for bone transplantation: 1 The free bone piece of the sputum is carved, so that its shape, size and thickness are in close contact with the plant bed. The processed bone graft is placed in the bone wound under the periosteum. If there is a large gap, the small bone piece can be used to fill, plug and suture the periosteum; 2 the free bone piece taken from the humeral condyle can also be decomposed. Become a small piece of fracture, and build it in the bone defect area, pay attention to the close contact between the bone pieces and suture the periosteum. 4. The soft tissue below the defect area is made into a transition flap or a translocation flap covering area. The skin scar was removed and the skin wound was repaired with a transition flap or a translocation flap. If the range of the bone graft is large, the local area should be sutured. Postoperative compression dressing.
