Correlation of the Clinical Outcome and Radiographic Measurement of the Calcaneal Fractures: Dong Eun Shin, Jin Yong Kim, Dong Bae Shin, Yong Jung Kim, Soo Hong Han, Young Je Soung; J Korean Soc Fract 2001;14(4):698-705. Published online October 31, 2001; DOI: https://doi.org/10.12671/jksf.2001.14.4.698

PURPOSE
To evaluate the prognostic factors associated with the clinical outcome, which analysed with use of the Pearson correlation method in AOFAS score and radiographic measurement between normal and the affected site after operative treatment of the calcaneal fractures.
MATERIALS AND METHODS
We evaluated 13 patients(13 cases) who had unilateral calcaneal fractures. At the latest follow-up, we calculated the mean differences of the Bohler angle, gissane angle, heel height, calcaneal width, calcaneal length, talocalcaneal angle, talar declination angle, subtalar incongruity between normal and affected site on the lateral view of ankle and tangential view of the calcaneus. And then the correlation between radiographic measurement and the clinical outcome analysed by Pearson correlation method.
RESULTS
Heel height(correlation coefficient = 0.827, p-value<005) and subtalar incongruity(correlation coeffidient = -0.764, p-value<0.05) were closely correlated with the clinical outcome and the B hler angle showed lower correlation coefficiency(correlation coefficiency = 0.470, p-value : 0.104) compare to the heel height.
CONCLUSION
We suggested that restoration of the heel height and subtalar incongruity was significantly correlated to the clinical outcome after operative treatment of the calcaneal fractures.

PROPER SCREW LENGTH FOR FIXATION OF THE MEDIAL MALLEOLAR FRACTURE OF ANKLE: Dong Bae Shin, Soo Hong Han, Seung Soo Jeon; J Korean Soc Fract 2000;13(3):522-528. Published online July 31, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.3.522

Abstract PDF: PURPOSE
There is rare report about screw length in ankle fracture in spite of the anatomical characteristic that distal densest area can give enough purchase of screw threads for fixation of medial malleolar fragment. Purpose of the current study is to evaluate the results of screw fixation and to estimate proper screw length in medial malleolar fracture.
MATERIALS AND METHODS
Authors retrospectively reviewed 136 cases of medial malleolar fracture which had been performed from Janurary 1985 to December 1997. The patients were divided into 3 groups according to screw length ; under 34mm screw length (9 cases), between 35mm and 45mm (76 cases), over 46mm (50 cases). Each group was evaluated bone union time, clinical outcomes and radiological results by Meyer and Kumler.
RESULTS
Good and excellent results were achieved 121 cases (89%) on clinical result and 125 cases (91.9%) on radiological result by Meyer criteria. There were no statistical differences between three group, but the 35mm-45mm screw length group showed slightly faster union tendency.
CONCLUSION
In the treatment of medial malleolar fracture, around 40mm length screw is sufficient for fixation and it doesn,t need to use the screw over 45mm length for more rigid fixation.

Distal Femoral Physeal Injury in Adolescence: Dong Bae Shin, Yong Jung Kim, Young Soo Lee, Jun Cheol Choi, Dong Eun Shin, Jun Shik Baek; J Korean Soc Fract 1999;12(4):1058-1064. Published online October 31, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.4.1058

Abstract PDF: The purpose of this study was to evaluate the results of distal femoral physeal injury in adolescence after various treatment 5 which had been performed for the last 4 years. This study consisted of 9 distal femoral physeal fractures from August 1993 to May 1996. Average length of follow up was 21 months. We evaluated the functional status such as range of motion, instability, pain and sports activity. They showed no abnormalities. We also assessed the lateral distal femoral angle, mechanical axis deviation, femorotibial angle and leg length discrepancy using orthoradiogram. 4 Cases showed the lateral distal femoral angle differences(more than 5), 7 cases showed the mechanical axis differences(average : 11.8mm), 6 cases showed the remorotibial angle differences(average : 5.8) and 6 cases showed the leg length discrepancy(average : 4.6mm). So we carefully concluded that the adequacy of the reduction is the most important prognostic factor and there are some problems in radiological angle difference despite the anatomical reduction.

Reamed versus Unreamed Intramedullary Nailing after External Fixator Application in the Treatment of Open Tibial-Shaft Fracture: Dong Bae Shin, Joon Cheol Choi, Young Soo Lee, Yong Jeng Kim, Soo Hong Han, Dong Eun Shin, Yeun Ho Lee; J Korean Soc Fract 1999;12(2):272-276. Published online April 30, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.2.272

Abstract PDF: The authers reviewed 15 patients of open fracture of the tibial shaft who were treated by external fixation followed by intramedullary nailing. These fractures comprised two Type-I, two Type-II, four Type-IIIa, and seven Type-IIIb injuries. Ten patients were treated with unreamed intramedullary nailing and 5 patients were treated with reamed intramedullary nailing. The results were analyzed as followings: 1. All fractures had union at 5.2 months after intramedullary nailing and 4 true osteomyelitis were developed. 2. All osteomyelitis were developed for the patients who were treated with reamed intramedullary nailing. 3. There was no osteomyelitis who were treated with unreamed intramedullary nailing. 4. Delayed conversion to intramedullary nailing after control of pin tract infection had no effect for prevention of osteomyelitis.

The effects of the flbular stabilization in the treatment of tibio-fibula shaft fracture: Dong Bae Shin, Young Kyu Lee, Jang Yeob Ahn, Byung Kuk Cho, Dae Ug Hur; J Korean Soc Fract 1994;7(2):634-641. Published online November 30, 1994; DOI: https://doi.org/10.12671/jksf.1994.7.2.634

Abstract PDF: Many authors have been discussed effects of fibular stabilization in the healing of the tibiofibular shaft fracture. A-0 group recommand fixation of the fibular shaft fracture in treatment of tibio-fibula shaft fracture with rationale of more stability of tibial fracture site and anatomical restoration of tibio-fibula relationship and so better effect on ankle motion. The purpose of this study is to indentify the effect of fibula stabilazation on reduction state of tibial fracture site, change in ankle mortise and healing period of tibial fracture site. Authors performed fibula stabilization with 1/3 plate and screws in 8 cases of tibio-fibula shaft fracture and compare with 40 cases of tibio-fibula fracture without fibula stabilization in point of above mentioned three effects. The results were as follows. 1. O/R & I/F of the fibular fracture, had no effect on the reduction state of the tibial shaft fracture site but it was somewhat helpful to restoration of the ankle mortise owing to the restoration of the fibular length. 2. There were no significant differences in the weight bearing time and the union time of the tibial fracture between two groups. 3. We experienced 2 cases of implant failure on the fibular fixation site, due to shortening of the tibial fracture site and overloading of the fibular fixation site. In these 2 cases, ankle pain was debeloped before the implant-failure. From the above result, we suggest that fibula stabilization have no benefit in treatment of tibio-fibular shaft fracture.

A Clinical Experience of the Posterior Fractare Dislocation of the Hip Joint: Dong Bae Shin, Young Kyu Lee, Jang Yeob Ahn, Kyung Ho Jin, Young Kil Joo; J Korean Soc Fract 1994;7(2):628-633. Published online November 30, 1994; DOI: https://doi.org/10.12671/jksf.1994.7.2.628

Abstract PDF: After classification of posterior hip dislocation by Thompson and Epstein, some treatment guide lines became proposed upon each types. However the most importance in treatment of posterior hip dislocation is prevention of 2 major complications, avascular necrosis of femoral head and post-traumatic arthritis. Authors experienced 16 cases of posterior htp dislocalion from Jan, 1988 to Dec. 1992. We analysed results of 16 cases which were available for minimum 1 year follow-up(Type I : 4 cases, Type II : 5 cases, Type IV cases, Type V : 3 cases). The summary of our clinical experience were as follows; 1. Reverse Stimson method was very useful method in reduction of posterior dislocated hip. 2. Reasons for surgery were unconcentric reduction with intraarticular fragment, large acetabular fragment with instability and joint incongruity. 3. The incidence of osteoarthritis was high(56%) and there was no differences in its prevalance and severity according to each type of Epstein classification.
