Abstract
Proximal fifth metatarsal fractures are the most common foot fractures in children. Attempts to classify these injuries are misapplied and inadequately predict outcomes. This is the first study to identify factors associated with healing in pediatric fifth metatarsal fractures. In this retrospective cohort study (N = 305), proximal fifth metatarsal fractures were classified on radiographs by location on the bone, alignment (transverse or oblique), displacement (>2 mm), and completion through the bone. Based on the literature, they were secondarily sorted by category: apophyseal, intra-articular metaphyseal, extra-articular metaphyseal, and diaphyseal. Primary outcomes included times to healing, indicated by clinical symptoms, immobilization, and return to sports, as well as radiographic callus formation, bridging, and remodeling. Healing times were compared by ANOVA and linear regression. Location had a significant effect on times of immobilization and return to sports, but alignment, displacement, and completion were not associated with healing. When re-classified, the categories were also associated with immobilization and return to sports. Apophyseal fractures healed fastest and diaphyseal fractures required the most time to heal. There was no difference between extra- and intra-articular fractures. For every year of age, symptoms resolved about 2 days sooner. Neither gender nor body mass index (BMI) was positively or negatively associated with healing times. In conclusion, classifying fractures by apophyseal, metaphyseal, and diaphyseal is the most concise, accurate, and useful system. This is the largest series of nonoperatively treated proximal fifth metatarsal fractures in children and a robust standard to which surgical management can be compared.

Abstract
Myelomeningocele, characterized by extrusion of the spinal cord through a spinal canal defect, is the most common form of spina bifida, often resulting in lifelong disability and significant orthopaedic issues. A randomized controlled trial (RCT) has shown the efficacy of prenatal repair in decreasing the need for shunting and improving motor outcomes. However, no studies have evaluated the effects of prenatal repair on orthopaedic outcomes. The purpose of this study was to determine the rates of orthopaedic conditions in patients with prenatal and postnatal repair of myelomeningocele and compare the rates of treatment required. This study analyzes the relevant outcomes from a prospective RCT (Management of Myelomeningocele Study). Eligible women were randomized to prenatal or postnatal repair, and patients were evaluated prospectively. Outcomes of interest included rates of scoliosis, kyphosis, hip abnormality, clubfoot, tibial torsion, and leg length discrepancy (LLD) at 12 and 30 months. The need for orthopaedic intervention at the same time points was also evaluated. Statistical analyses included descriptive statistics and univariate analyses. Data for the full cohort of 183 patients were analyzed (91 prenatal, 92 postnatal). There were no differences in rates of scoliosis, kyphosis, hip abnormality, clubfoot or tibial torsion between patients treated with prenatal or postnatal repair. The rate of LLD was lower in the prenatal repair group at 12 and 30 months (7 vs. 16% at 30 months, P = 0.047). The rates of patients requiring casting or bracing were significantly lower in patients treated with prenatal repair at 12 and 30 months (78 vs. 90% at 30 months, P = 0.036). Patients treated with prenatal myelomeningocele repair may develop milder forms of orthopaedic conditions and may not require extensive orthopaedic management.

Abstract
SUMMARY This study aimed to determine treatment preference of various femoral fracture patterns in children by pediatric orthopedists and whether it is practice dependent. In September 1998, members of the Pediatric Orthopedic Society of North America were surveyed to determine their current preferences in treating each of four middle one-third femoral fracture patterns in four age groups. Forty-four percent (286/656) of those surveyed responded. For each fracture pattern, operative treatment was increasingly preferred over nonoperative as patient age increased, and the preferred treatments within the operative and nonoperative categories changed significantly as patient age increased. Fourteen specific cases of femoral head avascular necrosis were noted after rigid reamed and unreamed rodding. There is a statistically significant trend by pediatric orthopedists to treat older children's femur fractures operatively and younger children's nonoperatively. The consensus treatment is age dependent. The numerous cases of avascular necrosis after rigid rodding are a concern.

Abstract
This study evaluated the accuracy of plain radiographs and computerized tomography (CT) in assessing juvenile Tillaux fractures of the distal tibia. A simulated Tillaux fracture was made in four cadaver specimens and displaced 0, 1, 2, 3, and 5 mm. Plain radiographs and CT were performed on each specimen at each amount of displacement, and the results were compared with the actual amount of displacement present. Plain radiographs and CT were accurate within 1 mm in depicting the actual fracture displacement about 50% of the time. CT was more sensitive than plain radiographs in detecting fractures with >2 mm of displacement. Fracture displacement of >2 mm is generally considered an indication for fracture reduction. Because of its sensitivity in detecting fractures displaced >2 mm, CT is the preferred imaging modality in the assessment of juvenile Tillaux fractures.

Abstract
Stubbing injuries to the great toe can be a cause of occult open fractures and osteomyelitis. Five such patients were identified after conducting a retrospective review of injuries to the hallux between January 1998 and December 1998. The study was conducted to draw attention to the association between this trivial trauma and its possible complications. All five children had open fractures of the distal phalanx of the great toe. Osteomyelitis did not develop in the children whose injuries were recognized early and who were treated with antibiotics. However, three children with delayed diagnoses and treatment developed osteomyelitis. At a mean follow-up of 10 months (range, 9-11) after injury, all five fractures had healed with no active signs of infection. Two of these children experienced a partial growth arrest and two experienced a full growth arrest of the distal phalanx of the great toe, the significance of which is yet unknown. Clinical signs such as bleeding from the eponychium and a laceration proximal to the nail bed should alert physicians to the presence of a possible open fracture. Early detection and treatment of these injuries may reduce or eliminate hospital stays and prolonged intravenous antibiotic treatment for osteomyelitis.

Abstract
Cubitus varus may occur after supracondylar humerus fractures. Poor fixation, however, complicates operative treatment of cubitus varus. We discuss the use of external fixation in the treatment of cubitus varus. Five patients had humeral osteotomies with external fixation. The preoperative humeroulnar angle (HUA) averaged -24.2 degrees. The immediate postoperative HUA averaged 12 degrees, and the final angle averaged 13 degrees. Duration of external fixation averaged 8.9 weeks. Complications were one transient radial neurapraxia, one superficial pin infection, and one keloid. No loss of correction or motion occurred with external fixation; we recommend external fixation as safe and effective.

Abstract
PURPOSE To compare computed tomography (CT) and magnetic resonance (MR) imaging in the detection, localization, and characterization of tarsal coalitions. MATERIALS AND METHODS Preoperative CT and MR images were obtained for 10 feet in nine patients (eight male and one female patients), aged 11-18 years who were unresponsive to conservative therapy. Results from two blinded readers were compared with results from surgery. RESULTS Five calcaneonavicular and four medial subtalar coalitions were found at surgery. One patient had synovitis. CT depicted six coalitions and four were characterized correctly, but the fibrous coalitions were not characterized correctly. MR depicted all coalitions and seven were characterized correctly, including the fibrous coalitions. At MR imaging, proliferative synovitis was incorrectly characterized as a fibrous coalition. CONCLUSION These results suggest that MR imaging depicts all coalitions but may not be able to help differentiate synovitis from fibrous coalitions and that CT has limitations in the depiction of fibrous coalitions.

Abstract
The Gustilo and Anderson classification system is widely used to categorize open fractures. To assess its interobserver reliability, 10 patients with open fractures had photographic slides taken of their wound before and after operative treatment. These slides were then shown to a group of orthopaedic surgeons. After an explanation of the Gustilo and Anderson classification system and each patient's pertinent history and physical examination, the physicians were asked to classify the fracture. Agreement among the various raters was determined by Kappa analysis, which is the preferred measurement of interobserver reliability for nominal data such as classification schemes. Kappa analysis demonstrated only moderate agreement among the observers classifying open fractures using the Gustilo and Anderson system. This seems to indicate that, although useful, the Gustilo and Anderson open fracture classification system does have limitations; studies and treatment recommendations based on it should be interpreted with caution.

Abstract
A wide variety of disorders affects the pediatric hip. The most common of these are developmental dysplasia of the hip, Legg-Calvé-Perthes disease, and slipped capital femoral epiphysis. Magnetic resonance imaging and ultrasound improve the imaging of these diseases, but the ultimate impact of this technology on treatment is unknown. Complications of treatment for these and other pediatric hip diseases can be devastating; so much recent research concentrates on the etiology, prevention, and effects of these complications. Finally, these diseases occur in skeletally immature individuals, and long-term follow-up is essential for accurate evaluation of results.
