The Pattern of Occurrence of Fractures in Children and Adolescents and Its Managements Based on the Database of the Health Insurance Review and Assessment Service

PURPOSE: The purpose of this article is to report on the pattern of medical process and relative frequencies of fractures in children and adolescents. MATERIALS AND METHODS: The authors retrospectively analyzed the database of the health insurance review and assessment service regarding children and adolescents under 20 years old treated from 2008 to 2010. Newly registered numbers of fractures in children and adolescents according to sex, month, institution, and anatomical location were also reviewed. RESULTS: A total of 1,893,416 fractures occurred during three years; approximately 630,000 cases were treated during one year (approximately 562 cases among 10,000 people during one year). During one year, the most fractures occurred in June and the least in February. Senior general hospital consisted of 5.72%, 12.30% in general hospital, 19.28% in hospital, and 62.70% in clinics. Among the fracture sites, 0.05% were cervical fractures, 0.91% in sternum and thoracic vertebra, 1.35% in lumbar vertebra and pelvis, 12.79% in shoulder and upper extremities, 26.87% in lower extremities, 38.10% in wrist and hand, 1.01% in femur, 10.40% in lower extremities including ankle, and 8.52% in foot excluding ankle. The maximal incidence was age 14 years in male and 12 years in female. CONCLUSION: The authors reviewed the pattern of medical process and relative frequencies of fractures in children and adolescents.

Percutaneous Transphyseal Intramedullary Kirschner Wire Fixation for Pediatric Diaphyseal Forearm Fractures

PURPOSE: Percutaneous pin fixation is commonly applied for pediatric diaphyseal forearm fractures. We analyzed the results of percutaneous transphyseal intramedullary K-wires fixation for pediatric forearm fractures and evaluated the safety of this procedure in terms of growth. MATERIALS AND METHODS: Thirty-six pediatric patients with forearm diaphyseal fractures treated with transphyseal intramedullary K-wire fixation were reviewed retrospectively. Authors analyzed size and number of fixed K-wires and evaluated postoperative complications, bone length discrepancy and any deformity at the last follow-up. We also evaluated range of motion of wrist and forearm as a functional result. RESULTS: The mean age was 9.5 years old and the average period of follow-up was 53 months (range: 23-85 months). Single wire was applied in each bone, and 1.6 mm sized K-wire was most commonly used for radius fractures and 1.1 mm K-wire for ulnar fractures. There was one superficial pin site infection which was healed by conservative treatment. There were no other complications such as premature epiphyseal closure, discrepancy of forearm length or any deformity. All patients showed no significant difference in range of motion compared to opposite side at the last follow-up. CONCLUSION: Percutaneous transphyseal intramedulaary K-wire fixation is one of the effective and safe operative treatment for pediatric forearm fractures without any deleterious effects on subsequent growth of radius and ulna.

Retrospective Review of Kirschner Wire Fixation and Casting for Displaced Lateral Condylar Fracture of the Humerus in Children

This study was conducted to assess the optimum period for Kirschner wire fixation and cast immobilization for displaced lateral condylar fracture of the humerus in children. We retrospectively reviewed 12 patients with displaced lateral condyle humerus fracture, ranging in age from 3-9 y, with injuries that occurred between Jan 2005 and Dec 2006. All patients were treated with two Kirschner wire fixation and elbow immobilization. In all except 2 patients, the Kirschner wires were maintained for 3 to 4 weeks. Mean time for union was 3.78 weeks and mean humeroulnar arch motion at last review was 138.7 degrees. Only one patient had a 5 degree increased carrying angle in valgus as compared to the non-injured side, and 50% had prominent scars > 4mm. We conclude that fracture union can be expected within three to four weeks for most children after open reduction and fixation with 2 Kirschner wires.
