The Prognosis of Undisplaced Abduction Fracture of the Neck of the Femur: Young Bok Jung, Eui Chan Jang, Suk Kee Tea, Whui Jae Jin, Jung Nam Han, Jung Il Lim, Cheol Kyoung Park; J Korean Soc Fract 2001;14(2):159-165. Published online April 30, 2001; DOI: https://doi.org/10.12671/jksf.2001.14.2.159

Abstract PDF: PURPOSE
The aim of this study was to analyze frequencies, types, and treatment results of the undisplaced abduction fracture of the neck of the femur for the prediction of the prognosis. MATERIALS & METHODS: From February 1984 to February 1999, the population was selected from those who were admitted in our hospital with the diagnosis of the fracture of the neck of the femur(96 cases). Among them 34 cases of undisplaced abduction fracture who could be followed minimum 2 years were chosen. The types of initial injury, the degrees of the rotation into valgus, union and the incidences of avascular necrosis of the femur head were analyzed by plain radiographs and medical records.
RESULTS
The undisplaced abduction fracture of the neck of the femur were 34 cases(35%) of the whole 96 cases and 33 cases of them had been operated. In all the 34 cases we were able to see the bone union, however in 7 cases(20.6%) the avascular necrosis of the femur head were happened. The incidences of the avascular necrosis is related with the degrees of the rotation into valgus(p=0.004).
CONCLUSION
The undisplaced abduction fracture of the neck of the femur is known to the result in good prognosis. According to this study, not a few avascular necrosis of the femur head happened. As a results, although undisplaced abduction fracture regained to be paid intention to the incidences of the avascular necrosis and careful follow-up should be accompanied.

A Simplified Technique of Distal Locking Screw Fixation of Interlocking Nail: Young Bok Jung, Ki Ser Kang, Boo Sup Kim, Han Jun Lee, Whui Jae Jin; J Korean Soc Fract 1995;8(1):248-253. Published online January 31, 1995; DOI: https://doi.org/10.12671/jksf.1995.8.1.248

Abstract PDF: Failure to determine distal femoral screw hole position can sometimes prolong operating time for placing interlocking screw and increased radiation hazard. We attempted to assess progress in the insertion of distal locking screw with target device. Insertion method of distal locking screw in femoral nail that uses target device improved the accuracy of distal screw placement and reduced the radiation exposure. The authors analyzed 30 patients(33 cases) of the femur shaft fractures that treated by interlocking IM nailing using target divice in the Department of Orthpaedic Surgery, Chung-Ang university from August 1990 to July 1994. Among these patients, except 6 cases, all of the distal femoral drill holes attempted were successfully made with the first pass of a dirll without image intensiner monitoring. Compared with the commonly used free-hand method, our target divice assisted screw placement offer a reduction in the amount of time and radiation exposure to insert distal locking femoral screws.
