Femoral neck and intertrochanteric fractures: radiographic indicators of fracture healing.

Serial hip radiographs from 280 patients with proximal femoral fractures were analyzed retrospectively by 3 radiologists to evaluate conventional radiographic healing patterns. Patients with hemiarthroplasty or insufficient follow-up were excluded. In the remaining 41 patients, the fracture line and callus was assessed. Intertrochanteric fractures demonstrated increasing callus and sclerosis at the fracture site. No such association was seen in femoral neck fractures. Traditional indicators of fracture healing cannot be readily applied at the hip. Radiographic features relate more to fracture type and fixation method.

Selective coronary angiography was performed in 80 patients with early postinfarction angina. All patients showed stenoses in at least one artery. Two vessels were affected in 37.5%, three vessels, in 51.3%, one vessel, in 11.3%. In 8.8% of cases, left coronary-arterial trunk was affected in addition to other arteries. Complete occlusion of one or several arteries was noted in 62.5%. There were marked collaterals in 20% of patients. The only difference between patients who showed relative resistance to medication and those whose condition could be stabilized was in the number of occluded vessels (69.2 and 35.1%, respectively). Coronary arterial lesions were operable in 68% of cases.
