[Ab] Resumo:Background: The traction bed is a noninvasive device for treating lower back pain caused by herniated intervertebral discs. In this study, we investigated the impact of the traction bed on the lower back as a means of increasing the disc height and creating a gap between facet joints. Methods: Computed tomography (CT) images were obtained from a female volunteer and a three-dimensional (3D) model was created using software package MIMICs 17.0. Afterwards, the 3D model was analyzed in an analytical software (Abaqus 6.14). The study was conducted under the following traction loads: 25%, 45%, 55%, and 85% of the whole body weight in different angles. Results: Results indicated that the loading angle in the L3-4 area had 36.8%, 57.4%, 55.32%, 49.8%, and 52.15% effect on the anterior longitudinal ligament, posterior longitudinal ligament, intertransverse ligament, interspinous ligament, and supraspinous ligament, respectively. The respective values for the L4-5 area were 32.3%, 10.6%, 53.4%, 56.58%, and 57.35%. Also, the body weight had 63.2%, 42.6%, 44.68%, 50.2%, and 47.85% effect on the anterior longitudinal ligament, posterior longitudinal ligament, intertransverse ligament, interspinous ligament, and supraspinous ligament, respectively. The respective values for the L4-5 area were 67.7%, 89.4%, 46.6%, 43.42% and 42.65%. The authenticity of results was checked by comparing with the experimental data. Conclusions: The results show that traction beds are highly effective for disc movement and lower back pain relief. Also, an optimal angle for traction can be obtained in a 3D model analysis using CT or magnetic resonance imaging images. The optimal angle would be different for different patients and thus should be determined based on the decreased height of the intervertebral disc, weight and height of patients.

[Ab] Resumo:AIMS: The aim of this study was to describe the epidemiology of closed isolated fractures of the femoral shaft in children, and to compare the treatment and length of stay (LOS) between major trauma centres (MTCs) and trauma units (TUs) in England. PATIENTS AND METHODS: National data were obtained from the Trauma and Audit Research Network for all isolated, closed fractures of the femoral shaft in children from birth to 15 years of age, between 2012 and 2015. Age, gender, the season in which the fracture occurred, non-accidental injury, the mechanism of injury, hospital trauma status, LOS and type of treatment were recorded. RESULTS: A total of 1852 fractures were identified. The mean annual incidence was 5.82 per 100 000 children (95% confidence interval (CI) 5.20 to 6.44). The age of peak incidence was two years for both boys and girls; this decreased with increasing age. Children aged four to six years treated in MTCs were more likely to be managed with open reduction and internal fixation compared with those treated in TUs (odds ratio 3.20; 95% CI 1.12 to 9.14; p = 0.03). The median LOS was significantly less in MTCs than in TUs for children aged between 18 months and three years treated in both a spica (p = 0.005) and traction (p = 0.0004). CONCLUSION: This study highlights the current national trends in the management of closed isolated fractures of the femoral shaft in children following activation of major trauma networks in 2012. Future studies focusing on the reasons for the differences which have been identified may help to achieve more consistency in the management of these injuries across the trauma networks.

[Ab] Resumo:RATIONALE: Traumatic C1-2 dislocation associated with contiguous or noncontiguous cervical spine injury is rare. Moreover, there have been no reports describing traumatic C1-2 dislocation associated with multiple contiguous and noncontiguous cervical injuries. PATIENT CONCERNS: The authors present a case of a 20-year-old male with painful limitation of motion of the neck. This complex cervical injury occurred due to hyperextension of the head in a rotated position. The patient complained of neck pain that radiated to the left shoulder and arm, but he did not exhibit any neurological abnormalities. DIAGNOSES: The diagnosis of the patients was traumatic C1-2 posterolateral dislocation associated with type II dens fracture (Anderson and D'Alonzo classification), type II injury of the transverse atlantal ligament (Dickman classification), and unilateral facet fracture with subluxation of C6-7. INTERVENTIONS: The C1-2 posterolateral dislocation with type II dens fracture was successfully reduced by skull traction. The patient underwent anterior discectomy, open reduction, and fusion with plate fixation of C6-7 followed by posterior segmental fixation and fusion of C1-2. OUTCOMES: At his postoperative 1-year follow-up, solid fusion was noted with improvement of clinical symptoms. This is the first report of traumatic C1-2 posterolateral dislocation associated with multiple C2 injuries and noncontiguous subaxial cervical injury. LESSONS: A high index of suspicion and careful evaluation of entire cervical spine should be considered as the key to the proper diagnosis and treatment of traumatic C1-2 dislocation associated with contiguous and noncontiguous cervical injuries.

[Ab] Resumo:Objective : The aim of this study is to evaluate both the anatomical and functional consequences of our treatment protocol of diaphyseal femoral fractures in children under 6 years old Methods : We conducted a retrospective analysis of a series containing 50 children in Strasbourg University Hospital whom had traumatic diaphyseal femoral fractures and underwent conservative treatment by traction followed by casting with a mean follow-up period of 25 months. Results : All fractures healed without complications i.e. gait disorders, back pain and limitation of activity. Results showed a significant correlation between the initial varus angulation and shortening which could influence the final remodeling result within the first 24 months. Using the Receiver Operating Characteristic curve, we developed the Initial Displacement Index on Traction (IDIT) which is the sum of both the initial varus in degrees and the initial shortening in millimeters. Conclusion : The treatment by initial traction followed by a cast for childrens ≤ 6 years old gives clinical and radiological results comparable with those reported for immediate casting method. The hospitalization period is longer in the traction method but with less exposure to general anesthesia (GA) and risks of secondary displacements.

[Ab] Resumo:PURPOSE: to evaluate the risk factors for additional surgery after closed reduction of hip developmental dislocation Methods : closed reduction for developmental hip dislocation was performed on 72 patients, with a total of 82 hips (10 bilateral). Were included only patients with irreducible hip dislocation who were treated by overhead traction followed by closed reduction under general anaesthesia and spica casting. The mean age at the time of closed reduction was 10 months, with 82% of dislocation diagnosed after the age of 6 months. In 28 hips (34.1%), no additional surgical procedure was necessary, while 54 hips (65.9%) needed an additional surgery, consisting in Salter osteotomy in 40 hips (48.8%) or open hip reduction in 14 (17.1%). RESULTS: risk factors for the need of additional surgery were: older age at the time of reduction, male sex, high grade of hip dislocation (Tönnis grade 3 and 4, versus grade 1 and 2), and quality of hip reduction. All the patients older than 17 months at the time of closed reduction needed additional surgery. Bilateral hip dislocation had poorer Severin grading than unilateral dislocation. Poorer Kalamchi scoring was associated with older age and with the presence of the cephalic nucleus at the time of reduction. CONCLUSION: this study confirmed delayed diagnosis of hip dislocation leads to a more extensive treatment with poorer issue.

[Ab] Resumo:Vitreoretinal interface pathologies, such as vitreomacular traction syndrome, epiretinal membranes and macular holes are sight-threatening conditions and one of the important causes of vision defects and vision loss. To this date, vigilance with observation of how the vitreomacular traction resolves, or vitreoretinal surgery in more severe cases, were the only treatment options. Recent rapid progress in ophthalmology, especially in diagnostic and visualization techniques, provided better insight into the mechanisms taking place on the vitreoretinal surface, which enabled a more accurate selection of treatment options. Development of ophthalmic pharmacological procedures, such as treatment of vitreomacular traction syndrome with ocriplasmin, constitutes an innovative breakthrough in ophthalmology. The enzyme is a genetically engineered form of human plasmin, a component of blood coagulation cascade that has been envisioned for human therapy since 1950s. It has never been used for vitreolysis in ophthalmology before. The aim of this review is to analyze and compare therapeutic options for symptomatic vitreomacular adhesion and vitreoretinal traction, with particular emphasis on microplasmin. We reviewed the results of recent studies comparing ocriplasmin to other widespread treatment options, such as pars plana vitrectomy.

[Ab] Resumo:OBJECTIVE: The objective of our study was to assess the impact of axial traction during MRI of talar dome osteochondral lesions using a small-FOV coil. SUBJECTS AND METHODS: A prospective study of 33 patients undergoing high-resolution MRI of the ankle using a microscopy coil with and without axial traction was performed. Two radiologists independently measured the tibiotalar joint space width and semiquantitatively graded intraarticular joint fluid dispersion, cartilage surface visibility of the osteochondral lesion, and cartilage surface visibility elsewhere in the tibiotalar joint before and after traction. Patients were instructed to report any discomfort during ankle traction. RESULTS: None of the patients reported discomfort or other symptoms during ankle traction. The tibiotalar joint space significantly increased (increase in cartilage-cartilage distance, 0.5-0.7 mm; all, p < 0.05) after traction compared with before traction. The degree of intraarticular joint fluid dispersion and the cartilage surface visibility at the osteochondral lesion and elsewhere in the tibiotalar joint improved after traction (all, p < 0.05). CONCLUSION: Traction MRI of the ankle is safe and technically feasible. This study is the first to date to investigate the effect of ankle traction on the MRI assessment of talar dome osteochondral lesions. Traction improves cartilage surface visibility of talar dome osteochondral lesions.

[Ab] Resumo:To evaluate the efficacy and safety of Halo-pelvic ring traction in the treatment of severe kyphotic deformity secondary to spinal tuberculosis.Eighty patients with severe kyphotic deformity due to spinal tuberculosis were included in the study. Forty of those patients (experimental group) received Halo- pelvic ring traction before surgery and the rest (control group) received surgical treatment directly. Two groups were compared by means of the duration of surgery, intraoperative blood loss, correction of Cobb angle, change in patient height, and American Spinal Injury Association (ASIA) impairment scale.Halo-pelvic traction group achieved significantly (P < .05) better results than direct surgical treatment group by means of the time of surgery (244 ±â€Š58 minutes vs 276 ±â€Š47 minutes, P = .036), intraoperative blood loss (950 ±â€Š236 mL 1150 ±â€Š305 mL, P = .018), correction of Cobb angle (68.3 ±â€Š12.6 vs 55.6 ±â€Š13.8, P = .001), change in patient height (9.4 ±â€Š4.0 cm vs 6.8 ±â€Š3.8 cm, P = .024). The mean improvement of ASIA scale was more in the experimental group than in the control group (0.23 ±â€Š0.07 vs 0.15 ±â€Š0.06); however, the difference is not statistically significant (P = .09).Halo-pelvic ring traction before osteotomy can be applied in patients with severe spinal kyphotic deformity due to spinal tuberculosis to increase efficacy and safety of surgical treatment.

[Ab] Resumo:Cervical spinal fracture is a rare, but potentially disabling complication of trauma to the neck. Clinicians often rely on clinical decision rules and guidelines to decide whether or not imaging is necessary when a patient presents with neck pain. Validated clinical guidelines include the Canadian C-Spine Rule and the Nexus criteria. Studies suggest that the risks of a pathologic fracture from a simple rear end collision are negligible. We present a case of an individual who presented to an emergency department (ED) after a low speed motor vehicle collision complaining of lateral neck pain and had multiple subsequent visits for the same complaint with negative exam findings. Ultimately, he was found to have a severely pathologic cervical spine fracture with notable cord compression. Our objective is to discuss the necessity to incorporate clinical decision rules with physician gestalt and the need to take into account co-morbidities of a patient presenting after a minor MVC.

[Ab] Resumo:This case report describes the successful traction of 2 severely impacted canines. The patient, a 7-year-old girl, had good general health, nasal breathing, crossbite of the lateral incisors and canines, and a Class I molar relationship. The panoramic radiograph showed that the permanent canines were positioned above the roots of the lateral incisors, with the right canine in an accentuated inclination. The cephalometric analysis showed a skeletal Class III malocclusion with a predominance of horizontal growth. The Haas appliance associated with maxillary protraction was used during the first stage of treatment for 14 months. The second stage included the extraction of the deciduous molars, distal movement of the permanent molars to create space, and traction of the canines, and was associated with complete orthodontic treatment. The patient showed good esthetic and functional results at the end of treatment, verified by the stability over a period of 8 years after retention.
