One hundred and seventy-nine additional intracapsular fractures are added to the previously reported cases making a total of 514 to date.
The Smith-Petersen nail continued to be a satisfactory method of treatment for undisplaced fractures of the femoral neck in this series.
Displaced fractures remained a difficult therapeutic problem with an incidence of 44 per cent non-union in this series and avascular changes in 24 per cent of the united fractures.
The preliminary results with the telescoping Pugh nail in thirty selected displaced fractures were encouraging with non-union in only 10 per cent and avascular necrosis in 22 per cent of the united fractures.
