Purpose: To investigate the measured values of the talus in Koreans. Materials and Methods: We measured 88 tali from 44 cadavers that have been donated between December 2012 and December 2015. Of the cadavers, 27 were male and 17 were female. Their mean age was 73 years. The length and width of the talus were measured using a digital goniometer and vernier caliper. Results: The values of cadaveric measurement, mean maximal width and length, width and length of the dome anterior, width and length of the posterior facet, height and length of the trochlear medial facet, and height and length of the trochlear lateral facet were 43.6±2.6 mm, 56.5±3.3 mm, 32.5±2.0 mm, 42.2±2.7 mm, 22.2±2.2 mm, 34.7±2.0 mm, 15.3±1.3 mm, 33.3±2.9 mm, 25.3±3.3 mm, and 30.8±2.4 mm for men and 38.9±1.6 mm, 53.6±2.4 mm, 27.9±2.1 mm, 37.4±3.2 mm, 20.6±0.8 mm, 31.9±1.2 mm, 13.6±2.6 mm, 28.4±2.5 mm, 24.9±2.1 mm, and 28.9±1.4 mm for women, respectively. The size of the talus showed an accuracy of 86% when anteroposterior diameter was greater than 59 mm. A difference in the size of the right and left talus was not observed. The mean inclination and declination angles were 24.4°±4.2° and 28.2°±5.4° for men, and 24.6°±3.6° and 24.7°±6.7° for women (p=0.980, p=0.018), respectively, at least 15o, which showed a big difference for every object up to 37o. Conclusion: This paper, to the best of our knowledge, is the first study to measure the talus in Koreans. There were differences by gender and ethnicity in the in measured talus values. The measurements were smaller than European-Americans and greater than Japanese. [ABSTRACT FROM AUTHOR]

Purpose: Tarsal coalition results from defects during the developmental stage and produces ankle pain and limitations in the range of motions. Its incidence has been reported to be 1%, but there has not been any reports with respect to Koreans. Therefore, we evaluated the prevalence of tarsal coalition in Koreans. Materials and Methods: Between 2005 and 2014, we analyzed a total of 733 cases of foot and ankle magnetic resonance imaging (MRI) in our hospital. There were 391 men and 342 women. All MRI readings were read by a radiologist in our hospital. We classified the coalitions in accordance with the histological and anatomical characteristics, and calculated the prevalence in each group. Moreover, we tried to determine the prevalence of tarsal coalitions in accordance with sex, age, and proportion of the symptomatic tarsal coalitions. Results: There were a total of 11 MRIs of tarsal coalition--9 talocalcaneal coalitions, 1 calcaneocuboidal coalition, and 1 calcaneonavicular coalition. Nine tarsal coalitions were observed in men and 2 in women. Conclusion: Through this study, we found that the prevalence of tarsal coalition, including the asymptomatic patients, is similar to the previously known prevalence (1%). By getting more MRIs of the foot and ankle, we could better represent the prevalence of tarsal coalitions in Koreans. [ABSTRACT FROM AUTHOR]

Purpose: This study examined the factors affecting the treatment of diabetes mellitus foot patients who had undergone a Syme amputation. Materials and Methods: This study included 17 patients diagnosed with a diabetes mellitus foot and who had undergone a Syme amputation from January 2010 to January 2014. Some of the risk factors (age, body mass index [BMI], disease duration, smoking, ankle brachial index [ABI], HbA1c, serum albumin, total lymphocyte, C-reactive protein [CRP], and serum creatine) that affect the successful Syme amputation were analyzed. Results: The healing rate of a Syme amputation was significantly higher when the lymphocyte count was above 1,500 mm3 (p=0.029). The factors affecting the surgical outcome according to multivariate analysis were HbA1c and the BMI (p=0.014, p=0.013). Regarding reamputation, there was a significant difference with HbA1c, lymphocyte, and BMI (p=0.01, p=0.03, and p=0.01). No significant differences were observed with age, disease duration of diabetes mellitus, smoking, ABI, serum albumin, CRP, and serum creatine. Conclusion: The HbA1c level, BMI and total lymphocyte count are risk factors that must be considered for successful Syme amputation in patients with diabetic foot disease. [ABSTRACT FROM AUTHOR]
