Abstract

It has been emphasized that treatment of hemoral neck fracture is early anatomical reduction and rigid internal fixation to reduce severe complications such as avascular necrosis or non-union.Operative treatment were developed recently with development of radiological technique. This study reviewed twenty-nine patients of femoral neck fracture treated by internal fixation between December 1973 and December 1979. There are eleven casesof Garden's stage I or II fracture with multiple Knowles pinning and eighteen cases (All Gardens stage) treated with compression hip screw, and followed for a minimum of nine months with an average eighteen months. The results were as follows; 1. Eleven cases with minimal displaced fracture (Garden's stage I or II) treated by multiple Knowles pinning were revealed good results. 2. In total eighteen cases treated by compression hip screw, nine cases (Garden's stage I or II) were revealed good results and other nine cases (Garden's stage I or II) were revealed fair or poor results. 3. Eleven cases of mlutiple Knowles pinning and nine case of compressian hip screw used for undisplaced fracture (Garden's stage I or II) were revealed good results without regard to internal fixation devices. 4. Avascular necrosis were four cases in nine cases(44%) of displaced fracture. 5. Non-union were not found in this aeries.
