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.

Surgical Treament for Unstable Intra-articular Fracture of the Distal Radius with Rayhack's Transulnar Percutaneous Pinning Technique: Eui Chan Jang, Ho Sung Ryu, Jae Sung Lee, Jung Nam Han; J Korean Soc Fract 1999;12(2):422-428.

Abstract PDF: There has been many treatment modalities in the distal radius fracture. Although there is no doubt that external fixators have a role in the treatment of some highly displaced distal radius fractures, many unstable distal radius fractures may be treated adequately with far less complicated and intrusive percutaneous pinning technique. The purpose of this study was to evaluate indication and effectiveness of Rayhack's transulnar percutaneous pinning technique. Authors reviewed the unstable intra-articular fracture of the distal radius of 15 cases treated with Rayhack's transulnar percutaneous pinning technique between March 1994 and February 1997. At the final follow-up examination, the mean loss of radial length, radial inclination and volar tilt was respectively 0.4mm (3.9%), 2.0 (10.6%), 2.1 (14.7%). Posttraumatic arthritis was occurred in 1 case (11.1%) of less than 1mm residual articular step-off, 2 cases (40%) of more than 1mm and less than 3mm residual articular step-off, 1 case (100%) of more than 3mm residual articular step-off. Distal radioulnar joint synostosis by percutaneous pinning was not found. According to Demerit point rating system, excellent to good results were obtained in 73.3%. Authors suggest that Rayhack's pinning technique can be applied in terms of simple procedure, cost-effectiveness and functional outcome.

A Prospective Study of Fractures of the Tibial Shaft Treated with Intramedullary Interlocking Nail : Comparing One versus Two Distal Screws: Eun Woo Lee, Ki Ser Kang, Soo Yong Kang, Eui Chan Jang, Jin Woo Lee; J Korean Soc Fract 1997;10(2):303-308. Published online April 30, 1997; DOI: https://doi.org/10.12671/jksf.1997.10.2.303

Abstract PDF: In non-randomized prospective study, 67 tibial fractures were treated with intramedullary inter-locking nail. Patients were divided into 2 groups based on the number of distal locking screw. Group I was consisted of 33 fractures treated with one distal locking screw Group II was consisted of 34 fractures treated with two distal locking screws. The patients were followed up for an average of 12 months. There was no statistically significant difference between group I and II with regard to total operation time, fracture union time. However fluoroscopic time was significantly longer at group II than group I. Serial radiographs of patients in both group were analyzed for change of hardware and fracture healing postoperatively. No significant difference was found between two groups in fracture union time, hardware failure and complications in proximal and middle tibial fracture. But the angulation and locking screw breakage were significant in group I in distal tibia fracture. We concluded that fracture of the proximal and middle third of the tibia that require interlocking nail can be successfully treated with a single distal locking screw. However, in fractures of the distal one third, two distal locking screws should be required to prevent of angular deformity in sagittal plane and for stablefixaton. The use of a single distal locking screw reduces operation time, radiation exposure, local soft tissue discomfort and cost without compromizing fracture union.
