Ten coxae of nine patients with intracapsular fractures of the femoral neck were examined by magnetic resonance imaging (MRI). In five of the ten, specimens were obtained by needle biopsy and examined microscopically. Cases were staged into four groups: according to Garden's classification Stage I, II, III and IV. In some cases of Stage I and II, partial bone necrosis was detected by MRI. Even cases of Stage I or II with bone necrosis rarely suffered from the complication of late segmental collapse. In Stage III or IV cases, extensive bone necrosis was detected by MRI, and in these cases consideration had to be given to the possible occurrence of late segmental collapse. The low signal area surrounded by a zone of non-signal area (so called "band pattern") demonstrated on MRI corresponded to bone necrosis seen microscopically.
