RESUMO

BACKGROUND: The standard of care for tibial shaft fractures in young children is nonoperative management, while in adults, operative treatment is considered the mainstay. There are no clear guidelines on preferred treatment for adolescents. PURPOSE: This paper aims to 1) identify clinical and radiographic characteristics predictive of malalignment and 2) determine if treatment type affects malalignment risk. METHODS: This retrospective cohort study identified patients aged 12 to 16 years old with a tibial shaft fracture at a Level 1 pediatric trauma center. The primary outcome of interest was malalignment, classified as meeting one or more of the following: >5° coronal angulation, >5° sagittal angulation, translation (cortical width or 100% displaced), and/or rotational deformity. Comparative analyses were done to identify risk factors for malalignment. RESULTS: A total of 162 patients were included-initial treatment was "planned nonoperative" for 102 patients and "planned operative" for 60 patients. The malalignment rate was 34% in the planned nonoperative group versus 32% in the planned operative group. In a multivariate regression, older patients [odds ratio (OR)=-0.07, 95% CI: -0.13 to -0.01; P =0.024] and those with 100% initial displacement (OR=-0.35, 95% CI: -0.64 to -0.05; P =0.021) had decreased odds of malalignment, and having increased sagittal angulation (OR=0.02, 95% CI: 0.01-0.04; P =0.002) and a fibula fracture (OR=0.22, 95% CI: 0.03-0.41; P =0.023) increased the odds of malalignment. There was no difference in the rate of malalignment by initial treatment ( P =0.289). Having a planned nonoperative treatment (OR=22.7, 95% CI: 14.0-31.5; P <0.001) and having a fibula fracture (OR=8.52, 95% CI: 0.59-16.45; P =0.035) increased the time immobilized. CONCLUSIONS: This study provides insight into factors affecting tibial shaft fracture alignment among patients aged 12 to 16 years. This study suggests that the risk of malalignment is higher among patients with increased initial sagittal angulation and concomitant fibula fractures, but the risk of malalignment is comparable in patients initially treated nonoperatively and operatively. Although healing parameters on average were similar, nonoperative treatment results in longer immobilization time and time for unrestricted weight bearing. LEVEL OF EVIDENCE: Level III-retrospective comparative study.

RESUMO

BACKGROUND: The aim of this study is to assess the rate of distal ulnar growth arrest following physeal fracture and to identify specific risk factors for premature physeal closure. METHODS: A retrospective review of patients with a distal ulnar physeal fracture was performed at a single United States children's hospital. Patients without 6-month follow-up were excluded. Patient demographics, injury characteristics, treatment, and outcomes were abstracted. Fractures were classified by the Salter-Harris (SH) system. All follow-up radiographs were reviewed for changes in ulnar variance or signs of premature physeal arrest. RESULTS: Fifty-six children with distal ulnar physeal fracture at a mean age of 10.7±3.3 years were included with a mean follow-up of 1.9 years. The most common fracture pattern was a SH II (52.7%), versus SH I (29.1%), SH III (9.1%), and SH IV (9.1%). Of displaced fractures (41.1%), the mean translation was 40.2±38.3% the and mean angulation was 24.8±20.9 degrees. Eleven fractures (19.6%) demonstrated radiographic signs of growth disturbance, including 3 patients (5.4%) with growth disturbance but continued longitudinal growth and 8 patients (14.3%) with complete growth arrest. The average ulnar variance was -3.4 mm. Three patients underwent subsequent surgical reconstruction including ulnar lengthening with an external fixator, distal ulna completion epiphysiodesis with distal radius epiphysiodesis, and ulnar corrective osteotomy. Patients with displaced fractures and SH III/IV fractures were more likely to develop a growth disturbance (34.8% vs. 3.2%, P =0.003; 50.0% vs. 11.1%, P =0.012, respectively). Children with less than 2 years of skeletal growth remaining at the time of injury had a higher risk of growth disturbance (46.2% vs. 9.5%, P =0.007). CONCLUSIONS: SH III and IV fractures are more common injury patterns in the distal ulna compared with the distal radius. Growth disturbance or growth arrest occurs in ~20% of distal ulnar physeal fractures. Displaced fractures, intra-articular fractures, fractures requiring open reduction, and older children are at increased risk of distal ulnar growth arrest and should be followed more closely. LEVEL OF EVIDENCE: Level IV--case series.

RESUMO

BACKGROUND: Nasoorbitoethmoid (NOE) fractures impact growth of the craniofacial skeleton in children, which may necessitate differentiated management from adult injuries. This study describes characteristics, management, and outcomes of NOE fractures in children seen at a single institution. METHODS: A retrospective review of patients under 18 years who presented to our institution from 2006 to 2021 with facial fractures was conducted; patients with NOE fractures were included. Data collected included demographics, mechanism of injury, fracture type, management, and outcomes. RESULTS: Fifty-eight patients met inclusion criteria; 77.6% presented with Manson-Marcowitz Type I fractures, 17.2% with Type II, and 5.2% with Type III. The most common cause of injury was motor vehicle accidents (MVAs, 39.7%) and sports (31%). Glasgow Coma Scale and injury mechanism were not predictive of injury severity in the pediatric population ( P =0.353, P =0.493). Orbital fractures were the most common associated fractures (n=55, 94.8%); parietal bone fractures were more likely in Type III fractures ( P =0.047). LeFort III fractures were more likely in type II fractures ( P =0.011). Soft tissue and neurological injuries were the most common associated injuries regardless of NOE fracture type (81% and 58.6%, respectively). There was no significant difference in type of operative management or in the rates of adverse outcomes between types of NOE fractures. CONCLUSIONS: These findings suggest that pediatric NOE fractures, although rare, present differently from adult NOE fractures and that revisiting predictive heuristics and treatment strategies is warranted in this population.

RESUMO

RATIONALE: Nasotracheal intubation is an advanced airway modality used in specific contexts, such as limited mouth opening, macroglossia, cervical spine instability. In addition, it can be performed with the patient awake, especially when predictors a difficult airway are unknown. PATIENT CONCERNS: A 41-year-old male with a lesion in the C1 cervical vertebra, associated with a fracture of the right maxilla, was intubated through the nasopharyngeal route while awake. The forms of induction were discussed. DIAGNOSES: Based on the mechanism of trauma and on the report of pain, associated with imaging examination, fracture of the body of the right maxilla and a complex fracture of the anterior arch of the C1 cervical vertebra were diagnosed. INTERVENTIONS: In this case, we present a patient with trauma to the face and spine who was intubated through the nasopharyngeal route while awake and guided by video laryngoscopy and using a rigid cervical collar. The patient was operated on under total general anesthesia (propofol and remifentanil) and plates and screws were placed for maxillary osteosynthesis. The pain was alleviated with a peripheral block of the trigeminal nerve of the maxillary branch with 0.5% levobupivacaine. OUTCOMES: The patient woke up from surgery, was extubated uneventfully and without pain. Cervical spine injuries were followed up by the neurosurgery team for conservative treatment. LESSONS: Patients with neck injury and facial trauma may need a definitive airway either for emergencies or for elective procedures. Intubating the awake patient may be an option when the anatomy of the cavity is unknown, and inducing the anesthetic act without this knowledge may be a inappropriate option, due to the risk of intubation/ventilation difficulties.

Introducción: Las fracturas vertebrales múltiples son el resultado de traumatismos de alta energía. Se clasifican en contiguas cuando hay fractura de dos o más cuerpos vertebrales en forma adyacente y no contiguas cuando hay lesiones de varios niveles separadas por, al menos, una vértebra sin lesión. Objetivos: Evaluar la clínica y la cinemática de las fracturas vertebrales múltiples, establecer su distribución, evaluar la asociación con lesiones extravertebrales y detallar las complicaciones. Materiales y métodos: Estudio multicéntrico, prospectivo y observacional de pacientes con fracturas vertebrales múltiples. Resultados: 66 pacientes (26 mujeres y 40 hombres; promedio de edad 39 años) con 196 lesiones vertebrales, 55 no tenían déficit neurológico. Cinemática: 32 accidentes automovilísticos, 27 caídas de altura, 5 traumas directos y 2 traumas deportivos. Topografía: dos C0-C3, cuatro C3-C7, ocho C7-T1, 61 T1-T10, 91 T10-L2, 28 L2-L5 y una sacro. Combinación: 21 toracolumbar-toracolumbar y 8 torácica-torácica. Treinta y dos fracturas eran contiguas; 19, no contiguas y 15 tenían un patrón mixto. Veintiséis pacientes pre-sentaron 47 lesiones extravertebrales (20 politraumatismos), 12 traumas torácicos. Treinta y seis pacientes recibieron tratamiento conservador y 30 fueron operados. Conclusiones: La presencia de fracturas vertebrales múltiples es frecuente y son consecuencia de accidentes automovilísticos, la mayoría de los pacientes no tiene compromiso neurológico. El sector más afectado fue entre T2 y L5, la combinación más frecuente fue toracolumbar-toracolumbar, seguida de torácica-torácica. Las lesiones extravertebrales más frecuentes fueron traumatismos de cráneo y de tórax. Nivel de Evidencia: IV

Background: Multiple vertebral fractures (MVF) are the result of high-energy trauma. These can be contiguous (CMVF) when there is a fracture of two or more vertebral bodies in an adjacent way and non-contiguous (NCMVF) when there are lesions of various levels separated by at least one vertebra without injury. Objective: To evaluate clinical features and kinematics, establish distribution, evaluate association with extra-vertebral injuries, detail complications. materials and methods: A multicenter, prospective, and observational study. Patients with MVF. Results: Sixty-six patients presented 196 vertebral lesions, without neurological deficit in 55; 26 were women and 40 were men, with an average age of 39 years old. Kinematics: 32 car accidents, 27 falls from height, 5 direct traumas and 2 sports traumas. Topography: 2 C0-C3, 4 C3-C7, 8 C7TT1, 61 T1-T10, 91 T10-L2, 28 L2-L5 and 1 sacrum. Combination: 21 thoracolumbar-thoracolumbar and 8 thoracic-thoracic. There were 32 contiguous injuries, 19 non-contiguous injuries, and 15 mixed-pattern injuries. Twenty-six patients presented 47 extra-verterbral injuries (20 multiple trauma, 12 thoracic trauma). 36 patients received non-surgical treatment and 30 patients underwent surgery. Conclusion: The presence of MVF in spinal cord trauma is frequent, most do not show neurological involvement and are consequences of motor vehicle accidents. The most affected sector was between T2 to L5, the most frequent combination was thoracolumbar-thoracolumbar, followed by thoracic-thoracic; the most frequent were extra-vertebral injuries, mainly head and chest trauma. Complications: one patient had increased kyphosis; one, surgical site infection; and one patient died. Level of Evidence: IV

RESUMO

Forty-six pigs presented muscle weakness, hind limb paresis and paralysis, weight loss, lateral recumbency, and death in a clinical course of 7 to 10 days. Two pigs were necropsied and exhibited bone fragility, bone callus formation, and multiple fractures in the limbs, ribs, and vertebrae. Microscopically, there was a diffuse and marked decrease in thickness and number of trabeculae. These were disconnected, with a "free-floating" appearance, while the cortex of the long bones was thinned, with an increase of the cortical porosity by enlargement of Haversian canals and endosteal erosion and decreased osteoblastic activity. Flame atomic absorption spectrometry in liver samples revealed significant zinc overload (>2300ppm) and copper deficiency (<33.1ppm). In this communication, we present the first pathologic description of an outbreak of osteoporosis in pigs, and we also provide a brief review of metabolic bone diseases in pigs.

Quarenta e seis suínos apresentaram fraqueza muscular, paresia e paralisia de membros pélvicos, perda de peso, decúbito lateral e morte, com um curso clínico de 7 a 10 dias. Dois suínos foram submetidos a necropsia e exibiram fragilidade óssea, formação de calo ósseo, e múltiplas fraturas em membros, costelas e vértebras. Microscopicamente notou-se difusamente um marcado decréscimo na espessura e número de trabéculas ósseas. Essas estavam desconexas, com uma aparência de flutuação, enquanto o córtex dos ossos longos estava afinado, com um aumento da porosidade pela dilatação dos canais de Haversian, erosão endosteal e diminuição da atividade osteoblástica. Espectrofotometria por chama foi realizada em amostras de fígado, e revelou um excesso de zinco (>2300ppm) e deficiência de cobre (<33.1ppm). Neste trabalho, apresentamos a primeira descrição patológica de um surto de osteoporose em suínos, além de fornecer uma breve revisão de doenças metabólicas em suínos.

RESUMO

ABSTRACT: The border wall between the United States and Mexico consists of stretches of metal fencing of varying heights alternating and overlapping with areas of electronic surveillance. Despite national conversations centered around the social, environmental, economic, and political implications of this wall, there is a paucity of studies on deaths occurring in this region. Herein are described 2 cases of fatal injuries sustained from scaling the fence and accidentally falling onto the United States' side in New Mexico. These injuries are compared with those typically incurred in falls from lower and higher heights, and implications of both lateral and vertical expansion of the wall are discussed.
