Author take off the pelvic bone from the cadaver and made the accruate reconstructed the pelvic bone as well as normal bone. Then author setted the pelvic bone into the specialized acrylic globe as the normal person erect position. For the acetabular posterior wall, projected the radiologic beam from the 0°to 45°cephalad direction and then pelvic bone rotated internally 0°~45°, each section is 5°. For acetabular anterior wall, projected the radiologic beam from 0° to 45° caudal direction and pelvic bone rotated externally 0°~45°, each section is 5° too. From the pelvic bone experiments, author get on the good radiologic angle for acetabular anterior and posterior wall. Ane then make the radiologic projection for normal person as the pelvic experiment. In pelvic bone model experiment, For acetabular anterior wall and anterior colum, external rotation 20°~30° caudal tilting 30°~45° angle projection has good visualization. For acetabular posterior wall and posterior column (including anterior column partially), internal rotation 15°~20° cephalad tilting 15°~30°angle projection has the good visualization. In normal person experiment, For acetabular anterior wall and anterior column, external rotation 20°caudal tilting 30°angle projection shows the good visualization. For acetabular posterior wall and column (including anterior column partially) internal rotation 20°cephalad tilting 30°angle projection shows good visualization. From the pelvic bone model and normal person experiments, the following conclusion are obtained. 1. For posterior wall and posterior column(including anterior column partially), internal rotation 20°, cephalad tilting 30°view is good. 2. For anterior wall and anterior column, external rotation 20°, caudal tilting 30°view is good.

The skin defect with sensory impairment of volar aspect of fingers should be reconstructed for the better function of hand. The Neurovascular island graft has been used to provide sensation to volar surface the thumb and to replace pulp tissues avulsed from thumb or index finger. Authors performed neurovascular island graft for defective sensibility of finger tip loss in 14 cases since Jun. 1979 to Mar. 1985. The donor flaps were obtained from the ring finger in 9 cases and middle finger in 5 cases. Among 14 cases, the donor flaps were taken from the ulnar side of 3rd and 4th finger in 11 cases. We followed up the the patients from 7 months to 4 years and 6months and in last follow-up, recovery of protective sensation such as sharp/blunt discrimination, temperature discrimination, and touch/stroke discrimination, was good but two point discrimination and reorientation of sensa-tion were poor. Cold intolerance was developed in 11 cases, and longitudial linear scar band of donor digit was demonstrated in 12 cases.

We analyzed 34 cases of large bone defect caused by trauma, infection and tumor resection from July, 1979 to June, 1985. The bony defect were restored by vascularized fibular graft or vascularized fibular transposition. 22 cases were the traumatic segmental loss and 7 cases were infected ones and 5 cases were the loss following tumor resection. Vascularized fibular graft was performed in 19 cases and vascularized fibular transposition was performed in 15 cases. The 33 cases(97%) of 34 cases had obtained sound bony union and average union time had been 18.6 weeks. Even local infection in the bone, vascularized fibular graft or transposition can be performed. Grafted or transposed fibula had been hypertrophied about 1.2 times in anteroposterior and lateral film which had been measured in the center of the fibula. The most common complication was the clawing of first or second toe. If the ipsilateral fibula is intact, the vascularized fibular transposition is better and if not, vascularized fibular graft is preferred. Operation using the vascularized fibula is a excellent method for the restoration of large bone defect in long bone.
