ABSTRACT
BackgroundRecently, distraction osteogenesis has been widely used to treat brachymetatarsia. However, few papers have compared complications associated with this treatment. The purpose of the present study was to compare the complications between the first and fourth brachymetatarsia treated by distraction osteogenesis. MethodsWe performed distraction osteogenesis to 83 metatarsals in 41 patients between 1999 and 2012. A total of 30 metatarsals received treatment for the first metatarsal (Group A) while 53 metatarsals received treatment with the fourth metatarsal (Group B). ResultsThe complication rate in Group A (40%) was higher than that in Group B (18.9%). Those who had high percentage of lengthening gain were more likely to have complications. A cut-off value for lengthening gain developing complication was 41.3%. ConclusionComplication incidence after distraction osteogenesis was increased when lengthening gain was more than 41.3% for brachymetatarsia. In the 1st metatarsal lengthening, the most common complication was stiffness. In contrast, complications of the 4th metatarsal lengthening were pin-track infection and angular deformity.

Diaphyseal unicameral bone cysts of the long bone are generally known to originate near the growth plate and migrate from the metaphysis to the diaphysis during skeletal growth. In the case of unicameral bone cysts of diaphyseal origin, recurrence at the same location is extremely rare. We report a case of recurrence of a unicameral bone cyst in the diaphysis of the femur that developed 8 years after treatment with curettage and bone grafting. We performed bone grafting and lengthening of the affected femur with an application of the Ilizarov apparatus over an intramedullary nail to treat the cystic lesion and limb length discrepancy simultaneously.

The aim of this study was to establish a multi-center birth defects monitoring system to evaluate the prevalence and the serial occurrence of birth defects in Korea. Ten medical centers participated in this program. A trained nurse collected relevant records from delivery units and pediatric clinics in participating hospitals on a monthly basis. We observed 1,537 cases of birth defects among 86,622 deliveries, which included live births and stillbirths. The prevalence of birth defects was 1.8%, and the sex distribution of the birth defect cases was 55.2% male and 41.6% female. The highest proportion of birth defects was in the cardiovascular system (17.5%), followed by birth defects involving in the genitourinary system (15.6%). Chromosomal anomalies were detected 30.0 per 10,000 births. Of these chromosomal anomalies, Down syndrome was most frequently observed. This study led to an establishment of a multi-center active monitoring system for birth defects. To better understand the serial occurrence of birth defects in Korea, it is necessary to increase the number of participating hospitals and to launch on a nation-wide multi-center study.
