Abstract
The short term results of a prospective dual energy x-ray absorptiometry (DEXA) study of periprosthetic bone remodeling around titanium femoral stems proximally coated with hydroxyapatite are presented. Thirty patients underwent DEXA scanning on the 15th and 45th postoperative days, 12th, 18th postoperative month. DEXA showed global femoral periprosthetic remodeling during the first 18 postoperative months. However, no significant variation in bone mineral density occurred around the lateral metaphyseal regions, where cancellous bone is greatestFile in questo prodotto:
