Abstract PDF: PURPOSE
To evaluate the clinical results of modified tension band wire technique using cortical screw for treatment of displaced medial malleolar fractures of the ankle.
MATERIALS AND METHODS
From January 2001 to January 2003, 24 patients were treated by modified tension band wiring using cortical screw for medial malleolar fracture. The follow-up period was 12~35 months (average 18 months). There were 13 males and 11 females, and the mean age was 46 years. Fractures were classified by Lauge-Hansen's classification. The results were analyzed by Meyer and Kumler's criteria.
RESULTS
There were 13 cases (54%) of excellent, 9 cases (38%) of good, and one case of fair because of limitation of motion of the ankle joint and one case of poor which showed post-traumatic arthritis of the ankle.
CONCLUSION
Modified tension band wire technique using cortical screw can be an effective operative method for the treatment of displaced medial malleolar fractures of the ankle.

Surgical Treatment for Fractures of the Talus: Ho Rim Choi, Jang Geun Lee, Hun Hwi Choi, Sung Woo Choi; J Korean Soc Fract 2003;16(1):67-73. Published online January 31, 2003; DOI: https://doi.org/10.12671/jksf.2003.16.1.67

Abstract PDF: PURPOSE
To evaluate the clinical results and develope guidelines for surgical treatment of talus fracture.
MATERIALS AND METHODS
Among the 60 cases that were treated during March 1990 to November 2000, 34 cases were treated operatively and followed up for more than one year( range: 1 4.4 years ). They were analyzed retrospectively with questionnaire directly or by telephone interview, radiograms and medical records. Clinical results were evaluated by Hawkins 'scoring system.
RESULTS
25 out of 34 cases showed satisfactory results. Unisatisfactory results were seen in cases that we couldn 't achieve anatomical reduction due to severe communition, and also in case of delayed treatment due to associated trauma and soft tissue injury. Six out of 8 cases that showed no Hawkins 'sign developed avascular necrosis. However, satisfactory results were achieved through conservative treatment.
CONCLUSION
Satisfactory results could be achieved through early anatomical reduction and rigid internal fixation followed by aggressive rehabilitation. There was no differences in clinical results either by the surgical approach or method of internal fixation. Avascular necrosis was not essentially related to the clinical results.

Operative Treatment for AO Type C Supracondylar Fractures of the Distal Femur: Ho Rim Choi, Joon Min Song, Hee Kwon, Youm Gyu Ko, Jang Geun Lee, Chang Hun Yoon; J Korean Soc Fract 2002;15(2):166-172. Published online April 30, 2002; DOI: https://doi.org/10.12671/jksf.2002.15.2.166

PURPOSE
Treatment of supracondylar fracture of the distal femur is challenging because of its characteristic anatomy and common occurrence of severe comminution. We evaluated the clinical results of 15 cases of AO type C supracondylar fracture.
MATERIALS AND METHODS
From December 1990 to November 1999, fifteen of 27 cases of AO type C supracondylar fracture of the distal femur were treated operatively. Mean follow-up period was one year and 5 months (range, 1 year-3 years and 3 months). The mean age of patients was 43.6 years. Eleven cases were treated by internal fixation and four cases by Ilizarov. Clinical results were evaluated by Schatzker and Lambert criteria.
RESULT
There were 5 excellent, 4 good, 1 fair and 1 poor results (81% satisfactory) in 11 cases treated by internal fixation and 1 excellent, 2 good, 1 fair results (75% satisfactory) in 4 cases treated by external fixation. COCLUSION: To get satisfactory results, AO type C supracondylar fracture of the distal femur need to be reduced anatomically and require rigid internal fixation. External fixation using Ilizarov can be an effective method of treatment in cases of open fracture and severe comminution with osteoporosis.

Comparison of radial head excision and open reduction & internal fixation for comminuted radial head & neck fracture: Jae Gune Jun, Chul Hyung Lee, Sung Jun Han, Sang Seon Lee, Won Tae Choi, Ho Rim Choi, Jeong Woung Lee; J Korean Soc Fract 2001;14(1):106-112. Published online January 31, 2001; DOI: https://doi.org/10.12671/jksf.2001.14.1.106

Abstract PDF: PURPOSE
The goals of the present study were to compare of radial head excision and open reduction k internal fixation for comminuted radial head & neck fracture.
MATERIALS AND METHODS
From march 1993 to February 1999, Patients with fracture of radial head (Mason type III) who were treated at Dae-Jeon Sun General hospital were enrolled in the study. The average duration of follow up was 3 years and 3 months. Six patients(Group A) were treated with radial head excision and fourteen patients(Group B) were treated with open reduction and internal fixation.
RESULTS
By functional rating index(modified After B.F. Morrey et al), in Group A, the results were classified as excellent(1 patient), good(No patient), fair(2 patients), and poor(3 patients), and in Group B, excellent(4 patients), good(5 patients), fair(3 patients), and poor(2 patients).
CONCLUSION
We concluded clinically to obtain better outcome in group which were treated with open reduction and internal fixation than radial head excision. Therefore, though the treatment of choice for Mason type III radial head fracture was total excision, in consideration of complication, procedure to preserve radial head was desirable. We must give careful consideration to possibility of open reduction and decision of radial head excision.

New Bone formation in Vascularized Periosteal Flap over the Bone Defect of the Shaft of the Radius in Rabbit. : Early Radiological, Histological and Immunohistochemical Study of Osteogenesis: Jae Kwang Yum, Young Bok Jung, Mi Kyung Kim, Ho Rim Choi, Tae Yeul Yoo, Jung Nam Han; J Korean Soc Fract 1999;12(4):1003-1011. Published online October 31, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.4.1003

Abstract PDF: Vascularized periosteal flap(VPF) it thought to enable formation of new bone and promote union in bone defect without risk of complications in donor site. Studiol about the VPF thus far have been centered on the long term result than early change after YPF. The purpose of this study was to elucidate the process of new bone formation in early stage after YPF 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 findings 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 YPF is vigorously and uniformly osteogenic in its early stage. It it thought that this study could serve as a basic data for the future experimental studiol about VPF in animals and clinical application.
