Abstract:
[Objective]To study the pertinency of position of the lesser trochanter and lateral shaft of femur for internal fixation of fracture of the lesser trochanter.[Method]One hundred and twenty thigh bones were taken X-ray films on normotopia and lateral position,anatomical observation and measurement of the the lesser trochanter were completed with angel and length relative to lateral shaft of femur.[Result]Vertical axis length of the lesser trochanter was 26.38?2.44 mm and transverse diameter was 15.61?1.49mm.Its retroverted angle was 17.66??10.56?and uptilted angle was 26.33??3.33?.[Conclusion]The appropriate position in fixation of the fracture of the lesser trochanter is the point on the besctor of the lateral cortex of the femur on level of the lower of the lesser trochanter.Its retroverted angle is 10?-15?and uptilted angle is 25?-30?.The length of the screw is 45-50 mm,it is beneficial to design the plate in femur with the data.
