Selective femoral circumflex artery and retinacular artery DSA is an important technique for assessment of femoral head blood circulation and investigation on its influent factors after femoral neck fracture.

结果 12例中髋关节囊内出血1例，骨内出血7例， 12例均出现持带动脉损伤和血供减少；患髋牵引时支持带动脉供血减少；髋关节维持伸直内旋位时所有支持带动脉无明确显影或仅显示其主干。

Results Intra-articular hemorrhage was observed in 1 patient and intra-osseous hemorrhage in 7 patients. The injury of retinacular arteries and reduction of blood supply were found in each case. In the presence of hip traction, blood flow of retinacular arteries reduced markedly. Few branches and little femoral head blood perfusion were observed in all of retinacular arteries, while hip joint was internally rotated with the sick leg straightened in the patients.
