avulsion

撕脱
  • 文章类型: Case Reports
    学龄前儿童经常遭受创伤性牙齿损伤,特别是在他们两到四年的生活中。由于乳牙周围的牙槽骨弹性,这些损伤中的大多数会导致牙齿撕脱。这项研究解释了在比赛中遭受的损伤的实例,该损伤导致了主切牙的早期敲除。因此,使用受伤牙齿的天然牙冠创建了生物牙齿整合的空间维护者,孩子被要求定期随访。这种治疗可以被视为自然美学康复的一个很好的选择,因为它可以促进言语发育,改善口腔清洁度,恢复美学和咀嚼功能,并抑制舌头习性异常和咬合不正的发展。
    Preschoolers frequently experience traumatic dental injuries, particularly during their two to four years of life. The majority of these injuries result in tooth avulsion because of the alveolar bone resiliency around the primary teeth. This study explains an instance of damage sustained during play that resulted in an early knockout of the primary incisor. Hence, a biogenic tooth-integrated space maintainer was created using the natural crown of the traumatized tooth, and the child was asked to come for a regular follow-up. This treatment may be viewed as a great alternative for natural aesthetic rehabilitation as it promotes speech development, improves oral cleanliness, restores aesthetics and masticatory function, and inhibits the development of aberrant tongue habits and malocclusions.

    目的:撕脱牙的延迟重新植入导致强直,随后在2-4年内更换吸收和最终失去牙齿。为了防止牙齿脱落,可以用酸蚀刻根部表面以暴露存在于牙骨质层中的胶原纤维。此过程有助于牙周膜的正常再附着和再生。这项体外研究旨在评估用柠檬酸和EDTA溶液处理的模拟撕脱牙齿的脱水根表面上附着的培养的人牙周膜细胞(HPLC)的活力和数量。
    方法:本研究包括健全的人恒牙。牙齿的根部被切成薄片,风干1小时,分为以下三组:A组-对照组;B组-柠檬酸处理30分钟;C组-EDTA处理5分钟。然后将切片置于培养的HPLC中。经过24小时的潜伏期,切片在显微镜下可视化,并准备使用分光荧光计读取活的和死的HPLC,以及在Neubauer室中计数HPLC。
    结果:活的和死的HPLC的分光荧光强度显示出统计学上的显着差异(p=.003和p=.002),柠檬酸组活HPLC的平均强度更大(69.52±74.51),其次是EDTA组(31.39±9.12),对照组(-130.93±30.99)。EDTA组的死HPLC强度更大(19.43±47.31),其次是柠檬酸组(1.28±1.85),对照组(-2.77±0.76)。Neubauer小室中的细胞总数显示出统计学上的显着差异(p<0.001),柠檬酸组(10.83±4.08)计数较高,其次是EDTA组(2.92±2.92)。
    结论:在拔除牙的脱水根面应用柠檬酸30分钟,与EDTA治疗5分钟和对照组相比,效果更好。
    OBJECTIVE: The delayed re-implantation of avulsed teeth results in ankylosis, followed by replacement resorption and eventual loss of the tooth within 2-4 years. To prevent tooth loss, the root surface can be etched with acid to expose the collagen fibers present in the cementum layer. This process facilitates normal reattachment and regeneration of the periodontal ligament. This in-vitro study aimed to assess the viability and number of attached cultured Human Periodontal Ligament Cells (HPLC) on the dehydrated root surface of simulated avulsed teeth treated with citric acid and EDTA solutions.
    METHODS: Sound human permanent teeth were included in the study. The root portions of the teeth were sectioned into slices, air-dried for 1 h, and divided into the following three groups: Group A-control; Group B-Citric acid treated for 30 min; Group C-EDTA treated for 5 min. The slices were then placed in cultured HPLC. After a 24-h incubation period, the slices were visualized under the microscope and prepared for reading the viable and dead HPLC using a spectrofluorometer, as well as for counting HPLC in a Neubauer Chamber.
    RESULTS: The spectrofluorometer intensity for viable and dead HPLC showed a statistically significant difference (p = .003 and p = .002), with the mean intensity for viable HPLC greater in citric acid group (69.52 ± 74.51), followed by EDTA group (31.39 ± 9.12), and control group (-130.93 ± 30.99). The dead HPLC intensity was greater in the EDTA group (19.43 ± 47.31), followed by the citric acid group (1.28 ± 1.85), and the control group (-2.77 ± 0.76). The total number of cells in the Neubauer chamber showed a statistically significant difference (p < 0.001), with a higher count in the citric acid group (10.83 ± 4.08) followed by EDTA group (2.92 ± 2.92).
    CONCLUSIONS: The application of citric acid for 30 min on the dehydrated root surface of avulsed teeth demonstrated superior outcomes compared to both EDTA treatment for 5 min and the control group.

    背景:牙齿撕脱需要迅速再植,其中牙周膜(PDL)细胞活力的保存至关重要。已经探索了各种存储介质,然而,缺乏在不同妊娠阶段(羊膜穿刺术和足月)获得的羊水(AF)与HBSS之间的比较。
    目的:本研究旨在评估AF(羊膜穿刺术和足月)在不同时间点对HBSS维持PDL细胞活力和调节细胞凋亡的影响。
    方法:在α-MEM中培养的牙周成纤维细胞用100%AF(羊膜穿刺术)处理,100%房颤(足月),HBSS,在37°C孵育1、3、24和48小时,并使用MTT测定活力和AO/EB染色评估凋亡,24小时后通过荧光显微镜分析。使用单向ANOVA进行统计分析,多变量方差分析,和事后Tukey的多重比较测试(p<.05)。
    结果:羊水(羊膜穿刺术)显示出最高的光密度(OD),这意味着跨时间间隔的细胞活力最高,其次是AF(足月)和HBSS。虽然HBSS保持PDL形态,AF两组均显示形态改变.24小时后未观察到细胞死亡。
    结论:在本研究的局限性内,两个AF组在储存1,3,24和48小时后显示出维持PDL细胞活力的潜力。然而,关于它们作为存储介质的适用性,需要进一步调查。
    BACKGROUND: Tooth avulsion necessitates swift replantation, for which the preservation of periodontal ligament (PDL) cell viability is paramount. Various storage media have been explored, yet a comparison between amniotic fluid (AF) obtained at different gestational stages (amniocentesis and full-term) and HBSS is lacking.
    OBJECTIVE: This study aims to evaluate AF (amniocentesis and full-term) against HBSS in sustaining PDL cell viability and regulating apoptosis at different time points.
    METHODS: Periodontal fibroblasts cultured in α-MEM were treated with 100% AF (amniocentesis), 100% AF (full-term), and HBSS, incubated for 1, 3, 24, and 48 h at 37°C, and assessed using the MTT assay for viability and AO/EB staining for apoptosis, which was analyzed via fluorescent microscopy after 24 h. Statistical analysis was conducted using one-way ANOVA, multivariate ANOVA, and post hoc Tukey\'s multiple comparison tests (p < .05).
    RESULTS: Amniotic fluid (amniocentesis) exhibited the highest optical density (OD), which implies the highest cell viability across time intervals, followed by AF (full-term) and HBSS. While HBSS maintained PDL morphology, both AF groups showed altered morphology. No cell death was observed after 24 h.
    CONCLUSIONS: Within the limitations of this study, both AF groups showed the potential to sustain PDL cell viability after 1, 3, 24, and 48 h of storage. However, further investigation is warranted regarding their suitability as storage media.

    背景:研究表明,首次阴道分娩与肛提肌(LAM)损伤之间存在显着关联,这可能导致盆底疾病(PFD)。
    目的:本研究旨在确定初产妇阴道分娩后短期和长期LAM损伤的患病率及其对PFD的影响。
    方法:根据PRISMA方法进行系统评价。使用的数据库是Pubmed,科克伦,还有PEDro.证据的质量评估是使用关键评估技能计划(CASP)进行的。在存在分歧的情况下,研究的选择和评估均由两名研究人员和第三名审阅者完成。
    结果:从搜索,收集了57篇文章,纳入了符合资格标准的19例.发现LAM撕脱的患病率与阴道分娩有关,分娩后1年为13%至28%,分娩后1年为16%至29%。在20%和37%≤1年之间检测到气球,33%的妇女在分娩后1年以上,与撕脱相比似乎更常见。盆腔器官脱垂(POP)被认为是与LAM损伤相关的最常见疾病,似乎与性功能障碍有关.
    结论:阴道分娩后初产妇的LAM撕脱和裂孔区膨胀的患病率很高,与POP的发展有很强的直接关系。
    BACKGROUND: Studies show a significant association between the first vaginal delivery and injuries of the levator ani muscle (LAM), which can cause pelvic floor disorders (PFDs).
    OBJECTIVE: This study aims to identify the prevalence of short and long-term LAM injuries after vaginal delivery in primiparous women and its influence on PFDs.
    METHODS: A systematic review was conducted according to the PRISMA methodology. The databases used were Pubmed, Cochrane, and PEDro. The quality assessment of the evidence was carried out using the Critical Appraisal Skills Programme (CASP). Both the selection of studies and their evaluation were done by two researchers and a third reviewer in cases of disagreement.
    RESULTS: From the search, 57 articles were gathered, and 19 were included to match the eligibility criteria. The prevalence of avulsion of the LAM was found in association with vaginal delivery between 13% and 28% ≤ 1 year after delivery and between 16% and 29% > 1 year after delivery. Ballooning was detected between 20% and 37% ≤ 1 year, and 33% of women > 1 year after delivery, appearing to be more common when compared to avulsion. Pelvic organ prolapse (POP) was considered the most common disorder associated with injuries of the LAM, and there seems to be some connection with sexual dysfunction.
    CONCLUSIONS: Avulsion of the LAM and ballooning of the hiatal area have a high prevalence in primiparous women after vaginal delivery and have a strong direct relation to the development of POP.

    尽管对小儿内侧上髁骨折和上髁炎进行了充分的研究,在该人群中,肘关节内下phy撕脱和韧带损伤的模式值得研究,以告知最佳治疗策略。
    描述儿童和青少年肘部尺侧副韧带(UCL)撕脱伤和软组织损伤的发生和人口统计学相关性。
    横断面研究;证据水平,3.
    进行了机构审查委员会批准的审查,以确定2016年至2021年在三级儿科运动医学实践中连续治疗的内侧肘损伤患者。在损伤评估期间获得了射线照片,排除无移位的内侧上髁突炎和完全上髁骨折的患者,导致150例发生软组织损伤的患者发生在内侧上髁突(下突)远端进行研究。对X线片进行了评估,以评估从近端内侧上髁或远端尺骨上结节对UCL的骨性撕脱。没有骨性撕脱的影像学证据的损伤,但是临床检查结果与韧带损伤一致,被归类为放射学阴性的UCL损伤,如果检查中存在中度至重度肘部内侧肿胀或对内侧结构损伤的严重关注,则进行磁共振成像(MRI)以进一步评估这些损伤。评估这些MRI扫描以对UCL损伤进行分类并评估骨膜或软骨撕脱。
    总共150名患者(平均年龄,12.5±3.4岁;70名女性),55%(150/274)的整个内侧肘损伤人群,有一个下骨软骨损伤。在这些病人中,在X线片上检测到62岁的骨性撕脱,和88有一个影像学阴性损伤。除了62个射线照相撕脱,在影像学阴性损伤上获得的61次MRI扫描显示33次完整的UCL中断,导致63.3%(95/150)的患者完全韧带断裂。有了核磁共振扫描,诊断为UCL的软骨或骨膜撕脱37例(61%)。总的来说,所有150个骨下损伤中有66%有骨质,软骨,或骨膜UCL撕脱。软骨患者(平均年龄,10.3岁)和骨骼(平均年龄,10.6岁)的撕脱比中央韧带损伤的年轻(平均年龄,14.2岁)或骨膜(平均年龄,14.2年)撕脱(P=0.005)。损伤机制与MRI扫描中确定的UCL撕裂位置之间存在显着关联:创伤性跌倒与远端撕裂有关,投掷伤与近端撕裂有关(P<.001)。
    UCL中央韧带和撕脱性病变可在小儿肘关节内侧损伤后频繁诊断,其中大多数是完全受伤,并且可能需要MRI进行诊断。损伤的机制可以预测韧带损伤的位置,与UCL或骨膜的软组织损伤相比,在较年轻的年龄更容易出现骨软骨撕脱。这些损伤的患病率值得进一步研究非手术治疗或手术修复技术的最佳方案和结果。
    UNASSIGNED: Although pediatric medial epicondylar fractures and apophysitis are well studied, patterns of subapophyseal avulsion and ligamentous injuries of the medial elbow in this population merit investigation to inform optimal treatment strategies.
    UNASSIGNED: To describe the occurrence and demographic correlates of ulnar collateral ligament (UCL) avulsion and soft tissue injuries of the pediatric and adolescent elbow.
    UNASSIGNED: Cross-sectional study; Level of evidence, 3.
    UNASSIGNED: An institutional review board-approved review was conducted to identify consecutive patients with medial elbow injuries treated in a tertiary pediatric sports medicine practice between 2016 and 2021. Radiographs were obtained during injury evaluation, and patients with nondisplaced medial epicondylar apophysitis and complete epicondylar fracture were excluded, resulting in 150 patients with soft tissue injuries occurring distal to the medial epicondyle apophysis (subapophyseal) for study. Radiographs were evaluated for bony avulsion of the UCL from either the medial epicondyle proximally or the ulnar sublime tubercle distally. Injuries without radiographic evidence of bony avulsion, but with clinical examination findings consistent with ligamentous injury, were classified as radiographically negative UCL injuries, and magnetic resonance imaging (MRI) was performed to further evaluate these injuries if moderate to severe medial swelling of the elbow or significant concern for medial structural injury was present on examination. These MRI scans were evaluated to classify the UCL injury and assess for periosteal or cartilaginous avulsions.
    UNASSIGNED: A total of 150 patients (mean age, 12.5 ± 3.4 years; 70 female), 55% (150/274) of the entire medial elbow injury population, had a subapophyseal injury. Of these patients, 62 had a bony avulsion detected on radiograph, and 88 had a radiographically negative injury. In addition to the 62 radiographic avulsions, the 61 MRI scans obtained on those radiographically negative injuries revealed 33 complete UCL disruptions, resulting in 63.3% (95/150) of patients sustaining a complete ligamentous disruption. With the MRI scans, 37 (61%) cases of cartilaginous or periosteal avulsion of the UCL were diagnosed. Overall, 66% of all 150 subapophyseal injuries had a bony, cartilaginous, or periosteal UCL avulsion. Patients with cartilaginous (mean age, 10.3 years) and bony (mean age, 10.6 years) avulsions were younger than those with central ligament injury (mean age, 14.2 years) or periosteal (mean age, 14.2 years) avulsions (P = .005). There was a significant association between the mechanism of injury and the location of UCL tear identified on MRI scans: traumatic falls were associated with distal tears, and throwing injuries were associated with proximal tears (P < .001).
    UNASSIGNED: UCL central ligament and avulsion lesions may be frequently diagnosed after injury to the pediatric medial elbow, the majority of which are complete injuries, and may require MRI for diagnosis. The mechanism of injury may predict the location of ligamentous injury, and osteocartilaginous avulsions are more likely to present at younger ages than injuries to the soft tissue of the UCL or periosteum. The prevalence of these injuries merits further investigation into best protocols of nonoperative treatment or surgical repair techniques and outcomes.

    目的:提肌撕脱是盆腔器官脱垂(POP)的主要病因,主要通过断层轴面成像诊断。二维成像也可以对提肌成像。目的是通过评估断层超声成像获得的冠状平面来测试冠状平面评估在提上肌创伤诊断中的可重复性和有效性。
    方法:对接受访谈的女性进行回顾性研究,三级泌尿妇科病房的POPQ和四维经唇超声。对存档的体积数据进行后处理以进行评估;以及提上肌面积和估计冠状平面中的残余肌肉质量。测试了后两种措施的观察者间可重复性以及提上肌创伤与POP的各种措施之间的关联。
    结果:观察者之间的协议对百分比估计很好(ICC0.743),但对于面积测量来说是公平的(ICC0.482)。看到了六百二十四个女人,468(75%)有显著的临床脱垂。在137例(22%)中诊断出了完全的提上肌撕脱。平均TTS为2.7(范围0-12)。在冠状平面评估中,右侧和左侧的平均肌肉面积为1.47(SD0.76)cm2和1.55(SD0.74)cm2,分别(P=.005)。肌肉质量的平均估计值分别为76%和79%(P=.021)。这两项措施都与持久性有机污染物密切相关;然而,在预测POP方面并不优于TTS。
    结论:体积数据中的冠状平面评估是可重复的,对于评估提上肌创伤是有效的。肌肉质量估计可能比肌肉面积更好。
    OBJECTIVE: Levator avulsion is a major etiological factor of pelvic organ prolapse (POP) and is primarily diagnosed on tomographic axial plane imaging. Two-dimensional imaging can also image the levator. The objective was to test reproducibility and validity of coronal plane assessment for diagnosis of levator trauma by assessing the coronal plane obtained on tomographic ultrasound imaging.
    METHODS: A retrospective study of women who had undergone an interview, POPQ and four-dimensional translabial ultrasound at a tertiary urogynecological unit. Post-processing of archived volume data was performed for assessment; and levator muscle area and estimate of remnant muscle mass in the coronal plane. Interobserver reproducibility of the latter two measures and associations between various measures of levator trauma and POP were tested.
    RESULTS: Interobserver agreement was good for percentage estimates (ICC 0.743), but fair for area measurements (ICC 0.482). Six hundred and twenty four women were seen, 468 (75%) had significant clinical prolapse. Full levator avulsions were diagnosed in 137 (22%). Mean TTS was 2.7 (range 0-12). On coronal plane assessment average muscle area was 1.47 (SD 0.76) cm2 and 1.55 (SD 0.74) cm2 on the right and left, respectively (P = .005). It was 76% and 79% for average estimates of muscle mass (P = .021). Both measures were strongly associated with POP; however, they were not superior to TTS in predicting POP.
    CONCLUSIONS: Coronal plane assessment in volume data is reproducible and valid for evaluation of levator trauma. Muscle mass estimate may be a better measure than muscle area.

    骨盆前突撕脱性骨折是罕见的损伤,经常影响青少年参加运动。发生这种情况的原因是,由于上骨尚未完全融合,因此无法承受施加的牵引力。由于其复杂的肌肉结构,是穿过两个下肢关节的几块肌肉的起源,骨盆受伤的风险增加。骨盆撕脱伤的诊断很大程度上取决于影像学。检测软组织变化的最佳方法,包括肌腱或肌肉拉伤,骨髓水肿,血肿,软组织撕脱伤,是磁共振成像。它也是显示肌腱回缩的最佳方法,可以帮助临床医生发现可能从手术治疗中受益的患者。
    我们报告了6例青少年职业足球运动员在踢足球时遭受撕脱伤的案例。患者痛苦地限制了髋关节的活动范围,并且无法承受体重。他们中的一些人在体检时感到受伤区域的触诊疼痛。磁共振显示有或没有移位的骨碎片的骨生长板撕脱,经过保守治疗,具有出色的临床和放射学效果。
    为了准确诊断骨盆撕脱伤和临床处理,重要的是,每个照顾这个病人的人都知道常见的损伤机制,射线照相结果,和可用的治疗方法。
    UNASSIGNED: Pelvic apophyseal avulsion fractures are uncommon injuries that frequently affect adolescents while participating in sports. This occurs because the enthesis cannot withstand the tractional force applied because the apophysis has not yet fully fused. Due to its complex muscular structure, being the origin of several muscles that cross two lower extremity joints, the pelvis has an increased risk for such injuries. The diagnosis of pelvic avulsion injuries depends heavily on imaging. The best way to detect soft-tissue changes, including tendon or muscle strain, bone marrow edema, hematomas, and soft tissue avulsion injuries, is with an magnetic resonance imaging . It is also the best at showing tendon retraction and can help the clinician spot patients who might benefit from surgical treatment.
    UNASSIGNED: We report six cases of adolescents professional footballers that suffered avulsion injuries while playing football. The patients had painfully restricted hip range of motion and were unable to bear weight. Some of them on physical examination felt pain at the palpation of the injured area. Magnetic resonance revealed apophysis growth plate avulsion with or without displaced bone fragments that were treated conservatively with an excellent clinical and radiological outcome.
    UNASSIGNED: For an accurate diagnosis of pelvic avulsion injuries and clinical management, it is important that everyone caring for this patient population is aware of the common injury mechanisms, radiographic findings, and available treatments.

    目的:描述以前未报道的犬腕骨副Salter-HarrisI型骨折的成功手术治疗。
    方法:一个11周大的完整雌性金毛-贵宾犬十字架,怀疑从高处坠落后,有明显的左前肢跛行史。
    关于体检,患者在触诊时表现出严重的左前肢跛行和疼痛,以及左腕骨的活动范围。左前肢远端的正交X射线照片显示,副腕骨的I型Salter-Harris骨折,掌骨碎片近端移位。
    结果:患者接受了切开复位和内固定,其中骨折用两根1.1毫米克氏针复位和稳定。术后,患者最初使用腕关节屈曲绷带管理2周,然后使用软垫绷带维持至术后4周.患者恢复良好,并在去除腕骨屈曲绷带后舒适地行走和负重。术后4周和8周进行的重复X光检查显示骨折愈合充分,但显示出轻度的近端植入物移位。未进行植入物移除,由于患者在家中表现良好,植入物迁移出现静态,且未引起临床发病。
    结论:据作者所知,这是唯一报道的犬腕骨副骨Salter-Harris骨折病例,也是唯一描述的成功手术稳定病例.
    OBJECTIVE: To describe the successful surgical management of a previously unreported Salter-Harris type I fracture of the accessory carpal bone in a dog.
    METHODS: An 11-week-old intact female Golden Retriever-Poodle cross presented with a history of a marked left forelimb lameness following a suspected fall from a height.
    UNASSIGNED: On physical examination, the patient demonstrated a severe left forelimb lameness and pain on palpation and range of motion of the left carpus. Orthogonal radiographs of the distal left forelimb demonstrated a type I Salter-Harris fracture of the accessory carpal bone with proximal displacement of the palmar fragment.
    RESULTS: The patient underwent open reduction and internal fixation wherein the fracture was reduced and stabilized with two 1.1-mm Kirschner wires. Postoperatively, the patient was initially managed with a carpal flexion bandage for 2 weeks and then a soft padded bandage was maintained until 4 weeks postoperatively. The patient recovered well and was walking and weight-bearing comfortably following removal of the carpal flexion bandage. Repeat radiographs performed 4 and 8 weeks postoperatively demonstrated adequate fracture healing but showed mild proximocaudal implant displacement. Implant removal was not performed, as the patient was doing well at home and the implant migration appeared static and was not causing clinical morbidity.
    CONCLUSIONS: To the authors\' knowledge, this was the only reported case of a Salter-Harris fracture of the accessory carpal bone in a dog and the only described case of successful surgical stabilization.
