The authors attempted to assess the value of ultrasound for monitoring of the new bone formation at the site of distraction in patients undergoing limb lengthening after Bastiani. Twenty patients were assessed; 12 cases of femur lengthening and 8 cases of tibia lengthening. It was found, that ultrasound allowed to detect the new bone formation visible as hyperechogenic foci as soon as 4 to 14 days postoperatively, while regular radiology showed this only 4 to 8 weeks after operation. Detection of the new bone formation at the site of lengthening permits, in authors opinion, to choose an optimal onset of distraction and its pace according to the speed of bone formation. Regular ultrasound monitoring prevents premature bone union or disintegration of the newly generated bone in case of to slow or to fast distraction respectively. In two cases sonography early demonstrated cystic changes at the location of distraction. It also permits detection of an axial displacement of the fragments of bone in every case.
作者试图评估超声在监测接受巴斯蒂亚尼肢体延长术患者牵张部位新骨形成方面的价值。对20例患者进行了评估，其中股骨延长12例，胫骨延长8例。结果发现，超声能够在术后4至14天检测到作为高回声灶可见的新骨形成，而常规放射学检查仅在术后4至8周才能显示。作者认为，在延长部位检测到新骨形成有助于根据骨形成速度选择最佳的牵张起始时间及其速度。定期超声监测可分别防止在牵张过慢或过快时出现过早骨愈合或新生成骨的解体。在两例中，超声检查早期显示牵张部位有囊性改变。它还能在每种情况下检测到骨碎片的轴向移位。
