The purpose of this study is to elucidate the prognosis of untreated humeral neck fractures. Subjects were 12 patients (4 men and 8 women) of the humeral neck fracture, and their mean age was 83.7years old. None of them had been treated appropriately due to various reasons. Seven patients were missed the humeral neck fracture, and 5 patients rejected the recommended therapy. Mean period after injury was 27 months.
They were evaluated with following items; radiographic findings (at right after injury and 6 months after injury), range of motion of the shoulder and subjective satisfactions (mealing, dressing, and excretion)at final examination.
Radiographic findings were evaluated by Neer's classification; 2 part fracture (6 patients),3 part fracture (2 patients),4 part fracture (4 patients). Bone union were observed in 10 out of 12 patients at 6 month after injury. Mean range of flexion was 50 degrees, mean range of abduction was 30 degrees, and mean range of external rotation was 10 degrees.2 patients were subjectively unsatisfactory. A Strict treatment including reduction, fixation, and surgical treatment was not necessary for all senile patients, who were in poor risk.
