Prospective evaluation of a prenatal sonographic clubfoot classification system.

BACKGROUND: The purpose of this study was to prospectively evaluate our recently described fetal sonographic classification system for prenatal diagnosis of clubfoot. METHODS: Over 18 months, we prospectively enrolled consecutive pregnant patients evaluated for a prenatally diagnosed clubfoot. Prenatal sonographic scores assigned by a radiologist were compared to final clinical diagnosis and severity given by a pediatric orthopedic surgeon. Pearson's χ(2) test and logistic regression were used in statistical analyses on the subject level. Generalized estimating equations were used in analyses on the foot level to account for intrasubject correlation. RESULTS: There were 50 subjects, with 26 unilateral and 24 bilateral clubfeet, according to the prenatal ultrasound (US). A total of 51 (69%) of 74 feet and 36 (72%) of 50 subjects had a postnatal diagnosis of clubfoot. The accuracy of diagnosis in cases of a severe, moderate, and mild US score was 94, 70, and 25%, respectively (p = 0.003 comparing moderate-severe vs. mild). US severity correlated with the Dimeglio classification scoring system (Spearman's correlation 0.30). CONCLUSION: The fetal sonographic scoring system is predictive of clinical severity after birth, and improves the ability to counsel families with a prenatal diagnosis of clubfoot.

Complications of talus fractures in children.

BACKGROUND: Pediatric talus fractures are rare with variable rates of posttraumatic complications reported in the literature. The purpose of this retrospective study was to evaluate posttraumatic complications in children after talus fracture and report injury characteristics. METHODS: This study included 29 children with talus fractures sustained between 1999 and 2008 at an average age of 13.5 years (range, 1.2-17.8). Patient records and radiographs were reviewed to determine the mechanism of injury, fracture type, associated injuries, and treatment. Posttraumatic complications assessed were avascular necrosis, arthrosis, nonunion or delayed union, neurapraxia, infection or wound-healing problems, and the need for further unanticipated surgery. Clinical follow-up averaged 24 months (range, 6 mo-5 y). RESULTS: Twenty-nine children sustained a major fracture of the talar body, neck, or head. Avascular necrosis occurred in 2 patients (7%), arthrosis in 5 (17%), delayed union in 1 (3%), neurapraxia in 2 (7%), infection in 0, and the need for further surgery in 3 (10%). Both high-energy mechanism and fracture displacement corresponded to a greater number of posttraumatic complications. The number and severity of talus fractures increased in older children. CONCLUSIONS: In this case series, posttraumatic complications after pediatric talus fractures occurred more frequently after a high-energy mechanism of injury or a displaced fracture. Talus fractures occurred more commonly and with more severity in older children. LEVEL OF EVIDENCE: Level IV. Retrospective case series.

Patient-based outcomes after tibia fracture in children and adolescents.

INTRODUCTION: Tibia fractures are common in pediatric patients and time necessary to return to normal function may be underappreciated. The purpose of this study was to assess functional recovery in pediatric patients who sustain tibia fractures, utilizing the Pediatrics Outcome Data Collection Instrument (PODCI), in order to provide evidence-based information on post-injury functional limitations and anticipated recovery times. METHODS: 84patients (out of 264 eligible patients, response rate 32%) age 1.5-18 years treated for a tibia fracture at a large children's hospital between 1/07 and 4/08 completed a PODCI questionnaire at 6 and 12 months post-injury. PODCI questionnaires were compared to previously reportednormal controls using Student's t-test in six categories. RESULTS: At 6 months after injury, the Sports functioning PODCI score was significantly less than healthy controls in both the parent reports for adolescent (mean 88.71 versus 95.4) and adolescent self-report (mean 90.44 versus 97.1); these showed no difference at 12 months. DISCUSSION: For adolescents who sustain fractures of the tibia, there remains a negative impact on their sports functioning after 6 months that resolves by 12 months. Physicians can counsel their patients that although they may be limited in their sports function for some time after injury, it is anticipated that this will resolve by one year from the time of injury. LEVEL OF EVIDENCE: Level II.
