大腿骨頸部内側骨折に対し人工骨頭置換術を施行した高齢者の術前の経過

抄録

Preoperative course and walking ability were studied in 58 cases with femoral neck fracture that subsequently resulted in PCA hemiarthroplasty. Cases of rheumatoid arthritis and pathological fracture were excluded. There were 10 men and 48 women, aged from 51 to 94, with an average age of 78. In 9 of the cases, PCA hemiarthroplasty was performed more than three weeks after injury. Approximately 80% of the 58 had fractures resulting from simple falls. Three patients were injured during activities of daily living.
Before injury 24 cases had the ability of walking outdoors without a cane, 12 of walking outdoors with a cane, and 11 of walking indoors. Only one-third of those over 80 were able to walk outdoors without a cane. After injury 12 cases had been able to walk for a while. We thought that several of these had had a non-displaced fracture at first. Seven of the 12 had surgery three weeks or more following injury.
It was considered to be quite important to diagnose precisely by using bone scan, CT or MRI in cases in which there are no obvious symptoms and no fracture line shown on a plain radiogram.
