当科における上腕骨大結節骨折の治療指針

抄録

Clinical results of greater tuberosity fractures of the humerus were studied. Displacement of the greater tuberosity reguiring no reduction was determined. Twenty-two patients (14 men, eight women) were acute injuries (average age 52.5). Seven out of 22 patients underwent conservative treatment. Internal fixation was performed on the remaining 15 cases. Seven chronic patient (six men, one woman) with malunion of greater tuberosity underwent conservative treatment at other clinics. Both acute and chronic cases indicating a more than 4mm-displaced fragment of greater tuberosity fracture complained of disability due to impingement. We concluded that internal fixation should be performed on these more than 4mm-displaced fragment of the greater tuberosity fracture.
