Biomechanical comparison between the defect of femur lesser trochanter and the replacement and fixation 股骨小转子缺损及复位固定的生物力学比较
By means of indirectly reduction and fixation technique, it need not to stabilize the lesser trochanter as well as bone grafting. 应用间接复位技术,不需要固定小粗隆或内侧小粗隆植骨。
Results Under every load, the maximum stress of femoral neck concentrated on the region above lesser trochanter. 结果在各种载荷下,股骨颈和股骨干各有一个应力集中部位。
The clinical research and application of the internal fixator for lesser trochanter 股骨小粗隆固定器的临床研究与应用
The cross-sectional areas of the thigh was scanned by CT. Between lesser trochanter and medial and lateral epicondyle of femur, the thigh was sectioned four equal parts, the second, third and fourth sections were scanned by CT, the thickness was 8 mm; 大腿肌肉横断面积的测定采用螺旋CT断层扫描,部位在股骨小转子和内外侧髁之间平均分成4等份,取中间3个等分点所在的平面进行CT断层扫描,横断面层厚取8mm;
Methods Diaplasis the femoral lesser trochanter, reconstructing the femoral calcar, recovering the dissection shape of the femur neck fundus, and then replacing the artificial femoral head. 方法复位股骨小粗隆,重建股骨距,恢复股骨颈基底部解剖形态,再行人工股骨头置换术。
Objective Unstable intertrochanteric hip fractures are characterized by comminution of the posteromedial cortex and a fragment of variable size containing the lesser trochanter. 目的讨论股骨转子间骨折伴小转子骨折是否需要固定。
According to the clinical experience, the femur neck and inferolateral shaft of femur of the lesser trochanter are all the catagmatic range. 对比临床,股骨颈和小转子外下侧股骨干部分也是可能导致骨折的区域。
