Avulsion Fracture of The Medial Meniscus: A Case Report: Hyoung Soo Kim, Seung Rim Park, Joon Soon Kang, Woo Hyeong Lee, Kil Seok Ko; J Korean Soc Fract 2000;13(1):109-112. Published online January 31, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.1.109

Abstract PDF: Post-traumatic meniscal ossicle due to avulsion fracture of medial meniscus was very rare. They were often associated with meniscal tear, but caused symptoms without a tear, by mass effect from protruding meniscal contour. so it had to be differential diagnosised with free loose body in the knee joint. We experienced a symptomatic meniscal ossicle due to post-traumatic avulsion fracture of the posterior horn of medial meniscus, and managed with open reduction, internal fixation with screw and washer after arthroscopic examination. We report a rare case of meniscal ossicle in detail with literature

Assessments of Reduction for Supracondylar Humerus fractures in Children: Comparison of Clinical carrying angle, Baumanns angle and Metaphyseal-diaphyseal angle: Seung Rim Park, Hyoung Soo Kim, Joon Soon Kang, Woo Hyeong Lee, Seong Hwan Kim; J Korean Soc Fract 1999;12(3):660-666. Published online July 31, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.3.660

PURPOSE
The object of this retrospective study is to verify Baumanns angle as assessment methods of reduction for supracondylar fracture of the humerus in children and to confirm what is the more accurate assessment methods of supracondylar fracture of the humerus between Baumanns and metaphyseal-diaplyseal angle.
MATERIALS AND METHODS
34 cases of more than 1 years follow up after closed reduction and pinning were reviewed. Simple linear regression has been used for statistical analysis and Pearsons correlation coefficient(rho) has been used for comparison of Baumanns angle and metaphy seal-diaphyseat angle.
RESULTS
The results form simple linear regression, about a 10 change in Baumanns angle contributes to a change in the carrying angle of approximately 3.7 on the uninjured(=-0.372, r=-0.750, P<0.001) and injured( =-0.365, r=-0.759, P<0.001) arms. In comparison of Baumanns angle and metaphyseal-diaphyseal angle to predict final carrying angle, the correlation coefficient between Baumanns angle and carrying angle(r=-0.759) was higher than that between metaphyseal-diaphyseal angle and carying angle(r=-0.495) with statistical significant using Fishers rho(P<0.05).
CONCLUSION
The Baumannss angle after reduction can be reliably used to predict accurately the final carrying angle and is more accurate than the metaphyseal-diaphyseal angle to predict the final carrying angle.

Treatments of Intraarticular Calcaneal Fracture: Based on CT Classification and Comparison of Treatments: Seung Rim Park, Hyoung Soo Kim, Joon Soon Kang, Woo Hyeong Lee, Ju Sik Park; J Korean Soc Fract 1999;12(1):103-112. Published online January 31, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.1.103

Abstract PDF: The treatment modality of the displaced intraarticular calcaneal fractures is still controversial. The objectives of this study are to classify intraarticular fractures based on computed tomography and to compare the treatment results according to the classification and to consider the influence of Bohler angle to the prognosis of this injuries. From October 1989 to March 1997, 62 fractures(58 patients) who had been treated after calcaneal CT(computed tomography) were selected. The interval between the trauma and the last follw-up was mean 3.3 years(1.1-5.2 years). They had been treated with one of the three methods, that is, open reduction and internal fixation(OR/IF), Essex Lopresti or simple cast immobilization. The fracture was classified as type I(non-displced), type I(two part or split), type III(three part or split depression), type IV (four part or highly comminuted) based on CT according to Sanders et. al. The calcaneal scoring system proposed by Kerr et. al. was applied to the assessment of the treatment results, which may be more appropriate for non-parametric statistical test. The type I fractures had been treated only with cast immoobilization with or without manual reduction and all of the 4 cases(100%) have shown favorable(excellent or good) results. The OR/IF group(favorable results for 15 of 18 cases(83.3%) in type II and for 11 of 13(84.6%) in type III) have shown better results than those of other two group(P<0.05). The results between other two groups, that is, Essex-Lopresti operation group(favorable results for 4 of 8 cases(50%) in type II and for 1 of 3(33.3%) in type III)and cast immobization(2 of 5 cases(40%) in type II and for 0 of 2(O%) in type III) have made no significant differences(p>0.5). In type IV, there were no significant differences among the results of the three methods(p>0.1) and worse results than type II, III (p <0.05) probably due to difficulty in reduction of highly comminuted articular facets. The Bohler angle has given no significant influence to the final results(p>0.1). In conclusion, OR/IF has shown better results than closed modalities in the treatment of displaced intraarticular calcaneal fractures and may be the primary choice of treatment for these fractures. We have used Kruskal-Wallis H test and its approximation to chi-square distribution for comparison of three groups and Mann-Whitney U test and its approximation to normal distribution for two groups and have been aided by the computer program, SPSS in statistical calculations. The p-value was 0.05.

The Treatment of Comminuted Fractures of Distal Humerus with Rigid Internal Fixation and Early Motion: Seung Rim Park, Hyoung Soo Kim, Joon Soon Kang, Woo Hyeong Lee, Joo Hyung Lee, Seung Jun Park; J Korean Soc Fract 1998;11(1):28-33. Published online January 31, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.1.28

Abstract PDF

Comminuted fractures of distal humerus are difficult fracures to treat because of their rarity and associated significant comminution. The results of managing theses fractures non-operatively are limited by failure to get anantomical reduction and early mobilization, which often results in painful stiff elbow and/or pseudoarthrosis. The goals of open reduction are to preserve articular surface and restore elbow function. Hence an operative management with anatomical reduction of fragments becomes the treatment of choice for these fractures. Authors analyzed 17 patients, with 30 months follow-up on an average, who were treated with open reduction and rigid internal fixation followed early mobilization during the period from jan. 1991 to Dec. 1996. Following results were obtained. 1. According to the Muller's classification, type A was 4 cases(23.5%), type B was 4 (23.5%), and type C was 9(53%) 2. Excellent or good results were obtained in 12 cases(71%) by the criteria of Aitken and Rorabeck. 3. There were limitation of full extension over 5degreein all cases and no other severe complications causing disability of elbow.

Overgrowth and Remodelling after Femoral Shaft Fractures in Children: Seung Rim Park, Hyoung Soo Kim, Joon Soon Kang, Woo Hyeong Lee, Hyun Yang Chun; J Korean Soc Fract 1997;10(1):226-232. Published online January 31, 1997; DOI: https://doi.org/10.12671/jksf.1997.10.1.226

Abstract PDF: Fifty-two femoral shaft fractures in children, treated conservatively, were studied clinically and radiographically to access the overgrowth and it is related factors. Among them, we reviewed fourteen children(16 cases), who had angular deformities over 10 after union for the spontaneous correction of the angular deformity. They had an average follow-up of 40.5 months and 32.4 months. The results were as follows : 1. The average of the overgrowth was 9.9mm. 2. The overgrowth was influenced by the age, but was not promoted by other factors. 3. The average overgrowth of the age group between 4 and 9 was 10.8 +/- 2.7mm. 4. The average correction was 78% of the initial angular deformity, 77% had occurred at the physes and 23% at the fracture site. 5. There was no close relation between the remodelling rate and degrees of initial deformity.
