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.

Purpose: We conducted this study to discriminate transolecranon fracture- dislocation of the elbow from the anterior Monteggia lesion and to validate the differences of method of treatment. Materials and method: From March, 1998 to May, 1999, 3 cases of the transolecranon fracture-dislocation of the elbow were treated by open reduction and internal fixation.One of the three patients had simple oblique fracture of the olecranon combined with capitellum fracture and two had complex comminuted fracture of the olecranon. Functional outcome was assessed with elbow performance rating system of Broberg and Morrey. Results: At a minimum follow-up of 12 months, overall outcome was rated as exellent in two patients, fair in one. Average bone union peoriod was three months. Conclusion: Stable restoration of the accurate contour and dimension of the trochlear notch of the olecranon and early ROM exercise will lead to good result in transolecranon fracture-dislocation cases.

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.

Vascularized periosteal flap(VPF) is thought to enable formation of new bone and promote union in bone defect without risk of complications in donor site. Studies about the VPF thus far have been centered on the long term result than early change after VPF. The purpose of this study was to elucidate the process of new bone formation in early stage after VPF by radiological, histological, electron microscopical and immunohistochemical studies. In experimental group, segmental resection of bone including the periosteum was performed in fifty-six radii of immature New Zealand white rabbits preserving the periosteal circulation from median artery which is the main source of blood supply to the periosteum. In order to simulate the transplantation of VPF, the vascular pedicle of median artery and veins was dissected from adjacent soft tissue and the periosteum was longitudinally incised to remove the bone tissue in the periosteum. Thereafter the vascularized periosteum was repaired. From the first to fourteenth day after the simulated VPF, the finding in the VPFs were observed by radiological, light microscopical, scanning electron microscopical methods and activity of osteocalcin was measured by immunohistochemical method. In control group, the bone tissue and periosteum were completely removed from the mid-shaft of seven radii, thereafter the radiological findings were observed at 1, 2, 3, 4, 8, 12, 16th week and light microscopical findings were observed at 8, 16th week after operation. From the results of this study, it is concluded that VPF is vigorously and uniformly osteogenic in its early stage. It is thougt that this study could serve as a basic data for the future experimintal studies about VPF in animals and clinical application.

Purpose : The aim of this study was to elucidate the continiuty of ligament in chronic injury of the posterior cruciate ligament(PCL). Materials and Methods : Magnetic resonance imaging(MRI) of twenty-six PCL injury patients with grade II or III laxity and more than 5mm side to side difference on stress radiographs were reviewed in terms of ligamentous continuity and thickness of the ligament at average 7.2 months(range:1-36) after injury. Resalts: Eighteen PCLs(69%) showed continuity of PCL. When thickness of the ligament in cases without continuity was rated as zero, the average thickness of the PCLs as compared to intact portion of the ligament increased as the time from injury elapsed; 16.4% in 0∼2 months group(7 cases), 30.0% in 3-5 months group(6 cases), 53.8% in 6-8 months group(9 cases) and 80.0% in over 9 months group(4 cases). Conclusion: More than two thirds of PCLs in symptomatic chronic injury showed ligamentous continuity on MRI. The longer the interval from injury was, the thicker the PCL was.
