    AbstractA prospective radiologic and scintigraphic study was made of 15 joints in 12 patients who underwent transtrochanteric rotational osteotomy of the femoral head after identifying by preoperative superselective angiography which arteries should be preserved during surgery. The preoperative superselective angiography revealed that the blood supply to the femoral head was provided by the medial femoral circumflex artery in 12 joints and a branch of the internal iliac artery in 3 joints. These nutrient arteries were preserved during surgery. At the follow-up examination made after at least 2 years, there were no cases of collapse of the new femoral head weight-bearing site, and also there were no cases with a large cold area in the femoral head on the scintigram obtained 2 months postoperatively. For this operative procedure, the nutrient arteries of the femoral head should be confirmed by preoperative superselective angiography, and it is essential that these arteries be preserved during surgery.
