The purpose of this paper is to report the rare complicated radioulnar cross union following open reduction for fractures of the forearm bones. The case was 62 years old male who complained of swelling and pain on forearm by the car accident. Roentgenogram revealed forearm bones fracture. Atpost operative 4 months, roentgenogram noted new bone crossing between radius and ulna. Excision of new bane was performed with extraction of nail and inserted chips of muscle. Post operative course was satisfactory, showing 50 degree of range of motion (20 degree supination and 30 degree pronation) from fixed pronation position.

BACKGROUND: The atrial repolarization waves might contribute to ST segment depression during the exercise loading test. As atrial repolarization waves are opposite in direction to P waves, they could shift the ST segment in the absence of myocardial ischemia. METHODS: The exercise test in 20 patients was seemed false positive because of normal coronary angiogram. Twenty-six patients with at least one coronary stenosis > or =50% served as a true positive group. The P waves, PR segments and ST segment were studied in leads II, III, aVF and V4 to V6 in those 46 patients whose exercise ECG suggested ischemia. RESULTS: The finding of steeply downsloping PR segment, particularly in the inferior ECG leads, in patients with longer exercise time and higher exercise heart rate might predict a false positive exercise test in those with a normal rest ECG and no apparent reason for a false positive test. The combination of downsloping PR segments in two of three inferior leads plus either exercise duration > or =5 min or peak heart rate > or =130 bests/min idenified false positive tests with a sesitivity of 75% and a specificity of 81% to 89%. CONCLUSIONS: Atrial repolarization waves might play a role in exercise induced ST segment depression.
