Pediatric Spinal Trauma at a Single Level 1Trauma Center: Review of 62 Cases

Background@#Traumatic spinal injuries in children are uncommon and result in different patterns of injuries due to the anatomical characteristics of children’s spines. However, there are only a few epidemiological studies of traumatic spinal injury in children. The purpose of this study was to investigate the characteristics of traumatic spinal injury in children. @*Methods@#We retrospectively reviewed the cases of pediatric patients (age < 18 years) with traumatic spinal injury who were treated at a level 1 trauma center between January 2017 and December 2021. We divided them into three groups according to age and analyzed demographics, injury mechanism, level of injury, and injury pattern. @*Results@#A total of 62 patients (255 fractures) were included, and the mean age was 13.8 ± 3.2 years. There were 5 patients (22 fractures) in group I (0–9 years), 24 patients (82 fractures) in group II (10–14 years), and 33 patients (151 fractures) in group III (15–17 years). Both the Injury Severity Score and the Revised Trauma Score were highest in group I, but there was no statistical difference between the age groups. Fall from height was the most common injury mechanism, of which 63% were suicide attempts. The level of spinal injury was different in each age group, T10–L2 injury being the most common. In all age groups, the number of multilevel continuous injury was larger than that of single-level injury or multilevel noncontinuous injury. Surgical intervention was required in 33.9%, and mortality was 3.2%. @*Conclusions@#In our study, fall from height was the most common mechanism of injury, and there were many suicide attempts associated with mental health issues. Thoracolumbar junction injuries were predominant, and the rate of multilevel contiguous injuries was high. The support and interest of the society and families for adolescent children seem crucial in preventing spinal trauma, and image testing of the entire spine is essential when evaluating pediatric spinal injuries.

Delayed-Onset Leg Weakness Caused by Posterior Migration of a Herniated Disc to the Thecal Sac Mimicking Epidural Hematoma in a Flexion-Distraction Injury of the Lumbar Spine: A Case Report

OBJECTIVES@#To document the first known case of posterior migration of a herniated disc in a lumbar flexion-distraction injury.SUMMARY OF LITERATURE REVIEW: Lumbar disc herniation is sometimes confused with epidural hematoma, especially when the disc migrates posterior to the thecal sac. There has been no report of posterior migration of a herniated disc after a lumbar flexion-distraction injury.@*MATERIALS AND METHODS@#A 47-year-old woman with no pertinent medical history was diagnosed with a flexion-distraction injury of the L2–L3 vertebrae after a motor vehicle accident. The patient had no neurological deficit initially. Magnetic resonance imaging (MRI) showed a space-occupying lesion with T2 hyperintensity and T1 isointensity on the dorsal side of the thecal sac at L2–L3. After posterior lumbar fixation and fusion, progressive leg weakness occurred 1 week postoperatively.@*RESULTS@#A second operation revealed no evidence of epidural hematoma, but a sequestrated disc. Decompression and sequestrectomy were performed, and the patient's neurological status had recovered fully at 4 months postoperatively.@*CONCLUSIONS@#This case highlights the potential for posterior migration of a herniated disc with flexion-distraction injuries of the thoracolumbar spine. Discontinuity of the posterior annulus fibrosus on MRI may aid the distinction of posterior migration of a herniated disc from epidural hematoma. Because posterior migration of a herniated disc is associated with progressive neurological deficits, surgeons must consider decompression surgery when such herniation is suspected, even in the absence of neurological symptoms.

Septic pulmonary embolism resulting from soft tissue infection in a 5-year-old child

Septic pulmonary embolism occurs when septic material becomes detached from its origin and infiltrates into the pulmonary parenchyma causing significant clinical symptoms. It is uncommon in children and mostly related to intravascular catheterization, endocarditis, pelvic thrombophlebitis, and soft tissue infection. We report a case of a 5-year-old boy who experienced septic pulmonary embolism originating from a left shoulder abscess after traumatic injury. Magnetic resonance imaging of the shoulder revealed a multifocal subcutaneous and intramuscular abscess with septic arthritis. The initial chest radiograph showed suspicious pneumonic infiltration with nodular opacities. A percutaneous catheter was inserted to drain the shoulder abscess, and cefazedone, a first-generation cephalosporin, was administered intravenously. Two days later, a chest radiograph taken for the follow-up of the initial pneumonic infiltration with nodular opacities demonstrated aggravation of multifocal nodular lesions in bilateral lung fields, with one of the nodular cavities containing an air-fluid level. Despite the absence of significant respiratory symptoms, chest computed tomography showed multifocal necrotic nodules and cavity lesions with feeding vessel signs dominantly in the left lower lung field, which is characteristic of septic pulmonary embolism. Methicillin-susceptible Staphylococcus aureus was isolated from the shoulder abscess, whereas repeated blood and sputum cultures did not reveal any bacterial growth. With resolution of clinical symptoms as well as the finding of chest computed tomography, the patient was discharged 18 days after admission in a stable condition. Regression of the multifocal pulmonary nodular lesions was noticed on the subsequent chest imaging studies performed 45 days after the treatment.

Glomus Tumors of the Fingers: A Report of 66 Cases

PURPOSE: We reviewed 66 cases of the glomus tumors in the hands. The purpose of this study was to review the characteristic signs and symptoms of glomus tumors and the surgical outcomes. We made hypothesis that (1) our guideline for surgical excision are reliable and (2) our surgical technique is efficient and less harmful to the nail root. MATERIALS AND METHODS: The clinical diagnosis was made with occasional radiological studies and surgical excision was performed according to our indications. Patients with electrical shock-like pain by touching (the essential symptom) and at least 2 of 4 clinical signs and symptoms (cold hypersensitivity, paroxysmal pain that radiated proximally, blue discoloration, nail deformity for dorsal tumor or a palpable nodule for pulp tumor) underwent surgical excision. RESULTS: The duration of symptoms of the patients was about 5.3 years. No difference of prevalence was found in both hands, but the thumb and the middle finger were more affected than the other fingers. The mean follow up period was 2.4 years and none of the patients complained the same characteristic pain at the last visit. CONCLUSION: To the best of our knowledge, this report is the largest case series about glomus tumors in the finger tip. The clinical signs and symptoms are important to make a diagnosis of glomus tumors, and surgical excision is the treatment of choice.
