The mortality following surgery in patients with a recent MI is high. Standard advice is to wait for a minimum of 6 months. In urgent situations, this may not be possible. From Jan 2003 to Aug 2004, 10 patients were admitted with fracture neck of femur and a recent MI proven by ECG changes or raised troponin. There were 7 females. The mean age was 79.5 yrs (59–95yrs). The premorbid mobility and co-morbidities were noted. Echocardiography was done in all patients preoperatively to assess the cardiac function. All patients were seen by physicians and anaesthetist pre-operatively. The mean time from infarction to operation was 11.5 days (3–23 days). The patients underwent either Thompsons hemiarthroplasty or DHS. The anaesthetic was performed by a consultant. Most patients received spinal anaesthesia (7/9). The anaesthetic records could not be found for 1 patient. 6 patients died within a month and 1 patient died within 6 month of operation. Despite thorough preoperative work-up and consultant anaesthesia, the mortality following surgery for proximal femur fractures in patients with recent myocardial infarction is 70% at 6 months. To our knowledge, there are no published mortality figures for this situation. This is much higher than the reported mortality following proximal femur fracture.
Radiologically 22 ankles fused, three probably fused whilst 11 (30%) had evidence of non-union. The majority of subtalar joints failed to unite, reflected by the high rate of distal screw breakage. Primary bone grafting appeared to aid union however smoking, age and the use of an open approach did not seem to be significant factors. Other than non-union complications included two nail fatigue fractures, two deep infections, seven screw breakages, six wound problems and one fractured tibia. Post operatively the mean AOFAS score was 51, 25 patients were satisfied (of these 20% had radiological non-union) and 19 would undergo the same procedure again.
