Tibialis Anterior Tendon Transfer for Calcaneus Deformity in Children with Myelomeningocele: A Preliminary Report / 대한정형외과학회잡지

PURPOSE: To examine the results of tibialis anterior tendon transfer for the treatment of a calcaneus deformity in children with a myelomeningocele. MATERIALS AND METHODS: Twenty-seven feet in sixteen children were examined in this study. The mean age at the time of surgery was 7(+2) years (range, 4(+11)-14(+9)) and the mean follow up duration was 25 months (range, 15-50). Three-dimensional gait analysis and dynamic foot-pressure measurement were performed to analyze the results of the index operation. RESULTS: There was no recurrence or aggravation of the deformity. The sagittal kinematics of the ankle improved, and the relative impulse of the calcaneus decreased postoperatively. Those patients with an increased range of motion of the pelvic rotation during gait showed less improvement in the relative impulse of the calcaneus than those with a good range of pelvic rotation. They also had a lower range of knee sagittal motion and an increased range of abduction of the hip, and up-obliquity of the pelvis. CONCLUSION: A good range of motion of the hip and pelvis in coronal and transverse planes, and of the knee in the sagittal plane are important predictors of the functional transfer of tibialis anterior tendon in patients with a calcaneal gait in a myelomeningocele.

Osteoporosis Prevalence of Radius and Tibia and Related Factors Using Multiple Bone Sites Quantitative Ultrasound Measurement of the Korean Health and Genome Study Cohort Women / 대한지역사회영양학회지

This study was conducted to investigate osteopenia and osteoporosis prevalence of radius and tibia using Quantitative Ultrasound (QUS) and to identify affecting factors of osteoporosis. A total of 4,340 women aged 40 - 69 years, living in Ansung (rural) and Ansan (mid-sized) area, and free of illnesses affecting bone metabolism participated in the community-based cohort study. Among them 4,059 subjects measured radius bone density and 4,089 measured tibia. The T-score threshold, defined as or = 30) were significantly increased. The OR of osteoporosis decreased across increasing quartiles of intakes of Ca, P and Ca/P. Therefore, maintaining normal BMI and increasing Ca intake and Ca/P ratio may have a beneficial effect on bone health of Korean women.
