Background: Brachial plexus birth injury (BPBI) is a condition in which the brachial plexus is thought to be damaged during the birth process. Studies have cited a varying incidence rate ranging from 0.5 to 4.0 per 1000 live births. The purpose of this study is to evaluate birth claims data over a 15-year period to identify risk and protective factors for BPBI in the state of Colorado. Methods: A data request was made to the state hospital association for birth claims data. We requested all birth claims from the years 2000 to 2014. ICD9 codes for variables of interest included: BPBI, shoulder dystocia, heavy-for-dates, macrosomia, breech delivery, instrumented birth, birth hypoxia, and gestational diabetes. A multivariable logistic regression model quantified both risk and protective factors for the development of BPBI as odds ratios (ORs) with 95% confidence intervals (CI). Results: There were 966,447 birth records received from State Hospital Association. The BPBI incidence was 0.63/1000 live births. The mean (SD) birth weight was 3187 (572) g for the total population and 3808 (643) g for the BPBI births. Later admission year indicated a decrease in BPBI births (OR, 0.94; 95% CI: 0.92, 0.96/y). Asian, black, and Hispanic infants were more likely to have a BPBI than white infants. Shoulder dystocia (OR, 60.37; 95% CI: 47.90, 76.13) was the highest risk factor for BPBI followed by instrumented forceps birth (OR, 21.04; 95% CI: 12.22, 36.21), breech delivery (OR, 15.38; 95% CI: 5.60, 42.25), and gestational diabetes (OR, 4.46; 95% CI: 3.29, 6.57). Cesarean single births had the lowest risk for BPBI (0.27; 95% CI: 0.20, 0.37), whereas cesarean multiple births (2.33; 95% CI: 1.10, 4.94) and natural multiple births (3.20; 95% CI: 1.36, 7.55) were at higher risk when compared with natural single births and all were statistically significant at P<0.027. Colorado births had a decreased risk of BPBI compared with the United States each year from 2000 (0.82/1000 births vs. 1.6/1000 live births, P<0.001) to 2012 (0.56/1000 live births vs. 0.9/1000 live births, P=0.003). Conclusions: BPBI has decreased from 2000 to 2014. Historically Colorado has had a lower BPBI incidence than the United States. Shoulder dystocia, instrumented forceps birth, gestational diabetes, and breech delivery are the biggest predictors for BPBI. Increased awareness of shoulder dystocia and instrumented birth are hypothesized to have reduced these incidences. Nonwhites and Medicaid patients seem to be at higher risk for BPBI. Level of Evidence: Level II—Prognostic.
Background: Seymour fractures are important to recognize and treat promptly because injuries may result in growth disturbance, nail deformity, or infection. We hypothesize that the administration of antibiotics within 24 hours of injury will be associated with a decreased rate of infection.Methods: Patients younger than 18 years were included if clinical examination and radiographs demonstrated a Seymour fracture. The timing of antibiotic administration and treatment details were reviewed. The presence of superficial infections or radiographic evidence of osteomyelitis was recorded.Results: A total of 52 patients with 54 fracture that had greater than 30 days of follow-up and were included in data analysis. The average age at the time of injury was 10.2 years. Thirty-four (63%) of 54 patients were most commonly injured secondary to a crush type mechanism. The overall infection rate was 27.3% (15/54 fractures). Among the 29 fractures that received antibiotics within 24 hours of injury, 2 infections (6.9%) were noted at final follow-up. Delayed administration of antibiotics beyond 24 hours postinjury was observed in 17 fractures and was associated with an increased infection rate of 76.5% (13/17, P = 0.000). Conclusions:Early administration of antibiotics within 24 hours of injury is associated with a reduction in the development of infections. Patients with delayed antibiotic administration may be at high risk for early superficial infection or osteomyelitis. This study highlights the importance of early identification and appropriate treatment of Seymour fractures including the prompt administration of antibiotics following injury.
Background: Musculoskeletal disorders are common medical problems encountered by physicians and affected 126.6 million Americans in 2012. Musculoskeletal education has inadequate in United States medical schools. Objective: To determine the musculoskeletal competency of third year medical students. Methods: A cross-sectional 25-question nationally validated musculoskeletal competency exam was given to the third year medical students. A survey was given to second and third year medical students to assess students’ level of interest in musculoskeletal medicine and their feedback regarding the curriculum. Results: The mean score of the competency exam was 69.0%. There was 48/107 (44.9%) students’ who reached the minimum passing score of 70%. Free-response feedback from both classes featured themes of more hands-on learning, a longer clinical block, and more small-group learning sessions. Conclusions: Third year medical students scored relatively well on the exam. Student feedback suggests the 2-week musculoskeletal block is useful and relevant to their future careers.
Introduction: Premature radial physeal closure is a relatively rare occurrence in children. When isolated growth arrest of the radius with continued ulnar growth occurs, the resulting ulnar positive deformity leads to altered wrist mechanics and pain. Timely epiphysiodesis of the distal ulna with and without ulnar shortening osteotomy can address these issues, but continued ulnar overgrowth is a possible complication. We seek to evaluate the success rate of the primary epiphysiodesis of the ulna and associated clinical outcomes. Methods: A chart review was conducted at 2 children's hospitals from 2008 to 2019. Patients between the ages of 6 and 18 years old, with premature distal radius physeal closure, with or without positive ulnar variance, and > 2 months follow-up were included. We evaluated the following characteristics for each patient: demographics, initial cause of premature radial physeal closure, ulnar variance, additional procedures performed during epiphysiodesis, preoperative and postoperative pain, range of motion, instability. Summary statistics were conducted and expressed as proportions, medians and means. A paired t test evaluated change in ulnar variance for those who had an ulnar shortening osteotomy performed.Results: Thirty-one wrists among 30 patients were identified, and the median age at the time of surgery was 12.2 years (interquartile range: 3.4). Ulnar shortening osteotomies were performed in 53.1% of cases and distal radius osteotomy in 15.6%. Bone graft was utilized in 25.8% of the epiphysiodesis procedures. There were 2 failures of primary epiphysiodesis indicating an index success rate of 93.7%. The average ulnar variance correction was 3.1 mm (95% confidence interval: 1.9, 4.4). The mean physeal time to closure was 134 days. Preoperative symptoms were resolved for 90.6% cases at final follow-up. Conclusion: Ulnar epiphysiodesis successfully terminates ulnar physeal growth in 93.7% of cases. Preoperative symptoms were completely resolved with a median physeal closure of just over 4 months. Ulnar variance was corrected on average by 4.1 mm when a radial or ulnar shortening osteotomy was performed at the time of epiphysiodesis. Level of Evidence: Level IV-case series.
