Verma-Naumoff syndrome: a case report / Síndrome de Verma-Naumoff: a propósito de un caso

In skeletal dysplasias, there are short rib polydactyly syndromes, which traditionally differentiate into four lethal types. This report describes a case of Type III, which presented characteristics of Types I and II. A 38-year-old woman presented fetal growth restriction at 17 weeks and 6 days, decreased amniotic fluid, enlarged and hyperechogenic kidneys, and long bones below the 3rd percentile. Three weeks later, she developed anhydramnia. The couple did not consent to the performance of an invasive test for genetic diagnosis and chose to maintain the pregnancy. At 33 weeks, due to premature labor and interactivity, a cesarean section was performed, giving birth to a female baby, who died due to respiratory failure there were no vocal cords and no trachea visible at laryngoscopy. On physical examination, he had the phenotypic characteristics of the syndrome. An X-ray showed short ribs and severe pulmonary hypoplasia. After birth, the parents chose not to carry out a genetic study or an anatomical examination. Researchers have suggested that there is an intersection of the anatomical changes of the types. This case report supports this theory.

En las displasias esqueléticas, existen síndromes de polidactilia de costillas cortas, que tradicionalmente se diferencian en cuatro tipos letales. Este reporte describe un caso del tipo III, que presentó características de los tipos I y II. Mujer de 38 años con restricción del crecimiento fetal a las 17 semanas y 6 días, líquido amniótico disminuido, riñones agrandados e hiperecogénicos y huesos largos por debajo del percentil 3. Tres semanas después, desarrolló anhidramnia. La pareja no consintió en la realización de una prueba invasiva de diagnóstico genético y optó por mantener el embarazo. A las 33 semanas, debido al parto prematuro y la interactividad, se realizó una cesárea, dando a luz a un bebé, que murió debido a una insuficiencia respiratoria: no había cuerdas vocales ni tráquea visible en la laringoscopia. Al examen físico presentaba las características fenotípicas del síndrome. Una radiografía mostró costillas cortas e hipoplasia pulmonar severa. Después del nacimiento, los padres optaron por no realizar un estudio genético ni un examen anatómico. Los investigadores han sugerido que existe una intersección de los cambios anatómicos de los tipos. Este reporte de caso apoya esta teoría.

Rehabilitación implanto protésica en paciente con injerto mandibular de larga data / Implant-prosthetic rehabilitation in a patient with a longstanding mandibular graft / Reabilitação protética com implantes em pacientes com enxerto mandibular de longa data

En la actualidad es cada vez más frecuente la consulta de pacientes que siendo sometidos en edades tempranas a cirugías de extirpación tumoral y posterior reconstrucción con injertos presentan problemas tanto funcionales como estéticos, el uso de prótesis implantosoportadas mejora la calidad de vida, pero al mismo tiempo representan un desafío por la baja disponibilidad ósea. Se presenta un caso clínico de rehabilitación protésica implantosoportada en una paciente con gran déficit óseo mandibular como consecuencia de le extirpación de una neoplasia y posterior injerto de costilla. Se colocaron 2 implantes osteointegrados en hueso remanente y rehabilitación con prótesis removible sostenida a una barra colada. Por ser un tratamiento poco invasivo y conservador fue aceptado fácilmente por la paciente y la mejora tanto en la estética como en la función fue notoria.

Nowadays, it is becoming more and more frequent to see patients who underwent surgery for tumor removal and subsequent reconstruction with grafts at an early age, presenting both functional and esthetic problems. The use of implant-supported prostheses improves the quality of life, but at the same time represents a challenge due to the low availability of bone. A clinical case of implant-supported prosthetic rehabilitation is presented in a patient with a great mandibular bone deficit as a consequence of the removal of a neoplasm and subsequent rib graft. Two osseointegrated implants were placed in the remaining bone and rehabilitation with a removable prosthesis supported by a cast bar. Being a minimally invasive and conservative treatment, it was easily accepted by the patient and the improvement in both esthetics and function was notorious.

Atualmente, são cada vez mais frequentes os pacientes submetidos à cirurgia de remoção de tumores e posterior reconstrução com enxertos em idade precoce que apresentam problemas funcionais e estéticos. O uso de próteses implanto-suportadas melhora a qualidade de vida, mas, ao mesmo tempo, representa um desafio devido à baixa disponibilidade de osso. Apresentamos um caso clínico de reabilitação protética implanto-suportada em um paciente com grande déficit ósseo mandibular em consequência da remoção de uma neoplasia e posterior enxerto de costela. Dois implantes osseointegrados foram colocados no osso remanescente e a reabilitação foi feita com uma prótese removível suportada por uma barra de gesso. Por se tratar de um tratamento minimamente invasivo e conservador, foi facilmente aceito pelo paciente e a melhora na estética e na função foi perceptível.

Genetic analysis of a pedigree of DYNC2H1 gene variation-caused short rib polydactyly syndrome type Ⅲ / 中华围产医学杂志

This paper reported the genetic analysis of a pedigree in which three affected fetuses with short limbs were revealed by first-trimester ultrasonography in three consecutive pregnancies. Tissues of the second aborted fetus were collected and analyzed by chromosome karyotype analysis and whole exome sequencing. The results indicated compound heterozygous mutations of EX64-EX83 Del and c.8190G>T in the DYNC2H1 gene. Real-time fluorescence quantitative polymerase chain reaction and Sanger sequencing further confirmed that the two variants were inherited from the father and the mother with normal phenotypes, respectively. EX64-EX83 Del was a likely pathogenic variant and c.8190G>T was a variant of uncertain significance. Based on the above results and the medical history, it was highly suspected that the fetus had autosomal recessive short rib polydactyly syndrome type Ⅲ caused by compound heterozygous variants. Real-time fluorescent quantitative polymerase chain reaction and Sanger sequencing results of the third aborted fetus were consistent with the second fetus. Given the same phenotypes of fetuses in the second and third pregnancy, it was strongly suggested that the heterozygous variations of EX64-EX83 Del and c.8190G>T in the DYNC2H1 gene were the pathogenic variants in this pedigree.

Efficiency and safety of traditional growing rod technique in the treatment of early onset dystrophic scoliosis secondary to type 1 neurofibromatosis with intraspinal rib head in children / 中华骨科杂志

Objective:To investigate the efficiency and safety of traditional growing rod in the treatment of early onset dystrophic scoliosis secondary to type 1 neurofibromatosis (NF1-DS) with intraspinal rib head in children.Methods:From September 2006 to May 2020, this study recruited 20 children with intraspinal rib head with early onset NF1-DS who had received traditional growing rods. There were 13 boys and 7 girls and the age of the initial operation was 7.0±1.6 years (range, 4.1-9.8 years). There were 7 cases of simple left chest bend, 9 cases of simple right chest bend, and 4 cases of double chest bend; 13 patients had varying degrees of kyphosis deformity. Two children had neurological symptoms before surgery, American Spinal Injury Association Impairment Scale (AIS) were grade D. The proportion of the intraspinal rib head (IRP), the Cobb angle of the main chest bend, apical vertebra rotation (AVR), apical vertebral translation (AVT), trunk shift (TS) and sagittal TK, lumbar lordosis (LL), sagittal balance and T 1-S 1 height were measured before and after first time internal fixation and at last follow-up, and the complications were also evaluated. Results:All 20 patients were followed up and the average follow-up time was 41.6±23.8 months (range, 24-99 months). A total of 85 operations was conducted including 63 protrude operations. After operation, the IRP was significantly lower than that before operation (preoperative 33.1%±17.5% vs. postoperative 22.2%±11.3%, P<0.001) and no significant correction loss was found at last follow-up 23.7%±12.4% ( P>0.05). The mean Cobb angle decreased from 75.9°±26.7° preoperatively to 45.0°±18.5° postoperatively ( P<0.001) and there was still significant improvement at the last follow-up (41.0°±17.2°) compared with postoperatively ( P<0.05). The AVR was significantly reduced after surgery compared with preoperatively (33.0°±10.1° vs. 39.3°±13.3°, P<0.001), and the last follow-up (40.1°±11.4°) was significantly improved compared with postoperative ( P=0.005). The T 1-S 1 height increased from 259.8±70.7 mm preoperatively to 296.9±78.4 mm postoperatively ( P=0.001), and at the last follow-up 296.9±78.4 mm was still significantly higher than after operation ( P<0.001), with an average annual increase of 12.4±3.2 mm. Significant correction of AVT, TK, LL and sagittal balance were noted after initial surgery ( P<0.05), and no significant correction loss was found at last follow-up ( P>0.05). There were 10 complications in 7 cases. There were 5 complications of pedicle screw loosening, 1 complication of bolt droping, 2 complications of broken rod, 1 complication of distal junctional kyphosis and 1 complication of adding-on phenomenon. 2 cases with nerve injury were recover after operation (AIS grading E). None of the children had new neurological complications during growth rod insertion and multiple stretching during follow-up. Conclusion:For children with early onset NF1-DS with intraspinal rib head, if the preoperative AIS grade is D or E, traditional growing rod technique is relatively safe and effective and can make the intraspinal rib head remove from the spinal canal partly.

Tumor de Células Gigantes em porção anterolateral de costela / Giant Cell Tumor in anterolateral rib portion

RESUMO: O Tumor de Células Gigantes é uma neoplasia osteolítica benigna, porém agressiva, ricamente vascularizada e com numerosas células gigantes com atividade osteoclástica. Ocorre mais frequentemente nas epífises de ossos longos e raramente acomete as costelas (cerca de 1% dos casos). A apresentação deste tumor em porção anterolateral de arco costal é extremamente rara em comparação com a região posterior. O presente relato descreve o caso de uma paciente que apresentava uma tumoração dolorosa em parede torácica anterolateral esquerda, de crescimento insidioso. Exames de imagem revelaram uma lesão insuflativa em 10º arco costal esquerdo (4,2 x 3,5 cm), com áreas de calcificação interior. A paciente foi submetida a tratamento cirúrgico, com ressecção ampla do tumor, englobando 9º, 10º e 11º arcos costais e uma porção do diafragma. O diagnóstico definitivo de tumor de células gigantes se deu pela imunohistoquímica da peça cirúrgica. Este relato permite fornecer bases para o estudo das possibilidades terapêuticas desta patologia em localizações atípicas, reforçando que a exérese em bloco com margens amplas destes tumores promove uma menor chance de recidiva local. (AU)

ABSTRACT: Giant Cell Tumor is a benign but aggressive osteolytic neoplasm, richly vascularized and with numerous giant cells with osteoclastic activity. It often occurs in long bone epiphyses and rarely affects the ribs (about 1% of cases). The presentation of this tumor in the anterolateral portion of the costal arch is extremely rare compared to the posterior region. The present report describes the case of a patient who had a painful tumor on the left anterolateral chest wall, of insidious growth. Imaging exams revealed an insufflating lesion in the 10th left costal arch (4.2 x 3.5 cm), with areas of interior calcification. The patient underwent surgical treatment, with wide resection of the tumor, comprising 9th, 10th and 11th ribs and a portion of the diaphragm. The definitive diagnosis of giant cell tumor was made by immunohistochemistry of the surgical specimen. This report provides a basis for studying the therapeutic possibilities of this pathology in atypical locations, reinforcing that the block excision with wide margins of these tumors promotes a lower chance of local recurrence.

Psychometric examination of Runco Ideational Behavior Scale: Thai adaptation

Creativity is a multidimensional construct. Several different approaches have been developed to measure creativity, including psychometric scales. The Runco Ideational Behavior Scale (RIBS) is one such measure of creative ideation. The primary purpose of this paper was to assess the 23 items of the RIBS in the context of the Thai language and examine scale reliability and validity. Participants, consisting of 508 undergraduate students selected from five Thai public universities, were selected through a convenience sampling approach involving both exploratory and confirmatory factor analysis. Results suggested that the Thai version of the RIBS presented a valid measure to a certain extent. Factor analysis of the empirical data indicated a two-dimensional structure. Confirmatory factor analysis (CFA) results confirmed that the two-factor construct demonstrated a better fit with improved psychometric characteristics. Six items were eliminated from the Thai RIBS version inventory: five items during explanatory factor analysis (EFA) and one during the CFA process. Results will contribute to ascertaining that the Thai version of the RIBS instrument can be used as a self-assessment tool for measuring students' creative ideation. Implications and limitations of this research are discussed with suggestions for future studies. (AU)

Anatomical variations and congenital anomalies of the ribs revisited by multidetector computed tomography / Variantes anatômicas e anomalias congênitas dos arcos costais revisitadas por meio da tomografia computadorizada de multidetectores

Abstract As they are asymptomatic or have a nonspecific, anatomical variations of the ribs are usually detected as incidental findings on imaging studies. They may be isolated changes or can be related to anomalies or clinical syndromes. Such variations are easily overlooked on conventional radiography and computed tomography if they are not actively investigated, mainly because most indications for a chest X-ray studies aim to evaluate the lung parenchyma and mediastinal structures. The objective of this pictorial essay was to use multislice computed tomography images to illustrate the imaging aspects of the main anatomical variations and congenital anomalies of the ribs.

Resumo As variantes anatômicas dos arcos costais são, geralmente, achados incidentais nos exames de imagem, em razão do seu comportamento assintomático ou quadro inespecífico, podendo constituir alterações isoladas ou relacionadas a anomalias e síndromes clínicas. Essas alterações são facilmente negligenciadas na radiografia convencional e na tomografia computadorizada se não forem investigadas ativamente, principalmente quando a maioria das indicações do estudo radiológico do tórax tem como objetivo a avaliação do parênquima pulmonar e das estruturas mediastinais. O objetivo deste artigo é demonstrar, por meio da tomografia computadorizada multidetectores, os aspectos de imagem das principais variantes anatômicas e anomalias congênitas dos arcos costais.

Study of dexmedetomidine combined with ropivacaine intercostal block on pain and sleep in patients with multiple ribsfracture / 中国医师进修杂志

Objective To study the effects of dexmedetomidine combined with ropivacaine for intercostal nerve block on pain and sleep in patients with multiple ribs fracture. Methods One hundred and seventy-eight patients with multiple ribs fracture were divided into two groups according to the random digits table method: control group (ropivacaine, 88 cases) and experimental group (dexmedetomidine combined with ropivacaine, 90cases). On the second day after admission, the patient underwent intercostal nerve block guided by ultrasound. Pain score of resting pain, cough pain and night pain at each time point and the sleep condition was compared after 3 days. Results In 4—7 ribs fracture patients, the resting pain score in the experimental group was significantly lower than that in the control group within 16 hours: (1.3 ± 0.6)scores vs. (1.7 ± 0.7) scores, (2.1 ± 0.4) scores vs. (2.2 ± 0.6) scores, (2.2 ± 0.3) scores vs. (2.3 ± 0.3)scores; while in the cough pain score, the experimental group was significantly better than the control group within 24 hours: (1.6 ± 0.8) scores vs. (2.5 ± 0.9) scores, (3.0 ± 0.7) scores vs. (3.3 ± 0.8) scores, (3.3 ± 0.7) scores vs. (4.0 ± 0.9) scores, (4.9 ± 1.0) scores vs. (5.4 ± 1.0) scores. The differences were statistically significant (P<0.05). In patients with more than 7 ribs fractures, the resting pain scoreand cough pain score ,the experimental group were significantly better than those in the control group within 12 hours (P<0.05). On the first day and the second day after the block, the insomnia scores in the experimental group were significantly lower than those of the control group: (2.5 ± 0.7) scores vs. (4.2 ± 1.6) scores, (2.8 ± 0.8) scores vs. (4.5 ± 1.5) scores. The difference was statistically significant (χ2＝7.374, 7.989, P < 0.05) . Conclusions For patients with multiple ribs fracture, the use of dexmedetomidine combined with ropivacaine for intercostal nerve block can improve the analgesic effect, prolong the analgesic time, and improve sleep quality.

The abnormality of the number of ribs misleading incorrect vertebral segment identification during lumbar intervention: Two cases report

BACKGROUND: For patients who have back pain or radiating pain, lumbar intervention should be performed at the correct lumbar segment that triggers pain. It is quite common for pain physicians to identify lumbar segments based upon the 12th pair of ribs to do an interventional procedure. CASE: We experienced two cases of rib number abnormality (absent 12th rib pair) that made the injection ineffective. In both cases, we had misidentified the lumbar segmentation due to rib abnormality. Although the procedure was performed properly, the clinical symptoms of the patient were not well correlated with the dermatome, and the diagnosis was delayed. CONCLUSIONS: These cases suggest that rib counting is necessary for more accurate lumbar segmentation. If the expected effect has not appeared after intervention, rib numbers should be checked.

Costal malformation related to thoracolumbar scoliosis in adolescents - case report / Malformação costal relacionada à escoliose toracolombar em adolescente - relato de caso / Malformación costal relacionada con la escoliosis toracolumbar en adolescentes - relato de caso

ABSTRACT Congenital scoliosis associated with costal malformation is well known. However, there are no reports of idiopathic scoliosis associated with the fusion of the costal arcs in the literature. This report describes a case of idiopathic scoliosis with fusion of the 1st and 2nd costal arches in a female patient and reports changes in the deformity due to scoliosis because of the treatment. The analysis was performed from a morphological and clinical point of view, and by complementary tests. Radiographs and CT scans were obtained and evaluated from the first consultation in 2012 and during the period in which the patient was followed in a private clinic, until the stabilization of the condition, in 2014. The evolution was favorable with the use of a Milwaukee vest and there was improvement of the clinical picture after the skeletal maturity, and the angle of lateral curvature, measured by the Cobb method, initially of 20 degrees, was reduced and stabilized in nine degrees, measure which is currently maintained. The analysis showed concomitant pathologies, and the fusion of costal arches did not influence the spine deformity, since there was regression with the clinical treatment. This evolution leads us to conclude that adolescent idiopathic scoliosis should be imputed as the sole responsible for the clinical picture of the patient, and that the fusion of the costal arches does not interfere with the biomechanics of the spine. Level of Evidence: IV. Type of study: Case series.

RESUMO A escoliose congênita associada à malformação costal é bem conhecida. Porém, não existe na literatura relatos de escoliose idiopática associada à fusão dos arcos costais. Este relato descreve um caso de escoliose idiopática com a fusão do 1º e 2º arcos costais em paciente do sexo feminino, e relata modificações da deformidade por escoliose em decorrência do tratamento. A análise foi realizada do ponto de vista morfológico, clínico e por exames complementares. Foram avaliadas radiografias e tomografias obtidas desde a primeira consulta, em 2012, e durante o período em que a mesma foi acompanhada em uma clínica particular, até a estabilização do quadro em 2014. A evolução foi favorável com uso de colete de Milwaukee e houve melhora do quadro clínico após maturidade esquelética, sendo que o ângulo de curvatura lateral, aferido pelo método de Cobb, inicialmente de 20 graus, reduziu e se estabilizou em nove graus, sendo que esta medida se mantém atualmente. Pela análise realizada, houve uma concomitância de patologias, sendo que a fusão de arcos costais não influenciou na deformidade da coluna, uma vez que a mesma regrediu com o tratamento clínico. Esta evolução nos leva a concluir que a escoliose idiopática da adolescente deve ser imputada como a única responsável pelo quadro clínico da paciente, e que a fusão dos arcos costais não interfere na biomecânica da coluna vertebral. Nível de Evidência: IV. Tipo de estudo: Série de caso.

RESUMEN La escoliosis congénita asociada a la malformación costal es bien conocida. Sin embargo, no existen relatos de escoliosis idiopática asociada a la fusión de los arcos costales en la literatura. Este relato describe un caso de escoliosis idiopática con la fusión del primer y segundo arco costal en paciente del sexo femenino y relata modificaciones de la deformidad por escoliosis como consecuencia del tratamiento. El análisis fue realizado desde el punto de vista morfológico y clínico y por exámenes complementarios. Se evaluaron las radiografías y tomografías obtenidas en la primera consulta, en 2012 y durante el período en el que la paciente fue acompañada en una clínica particular, hasta la estabilización del cuadro, en 2014. La evolución fue favorable con uso de chaleco de Milwaukee y hubo una mejora del cuadro clínico después de la madurez esquelética, siendo que el ángulo de curvatura lateral, medido por el método de Cobb, inicialmente de 20 grados, se redujo y se estabilizó en nueve grados, lo que se mantiene actualmente. Por el análisis realizado, hubo concomitancia de patologías, siendo que la fusión de arcos costales no influenció la deformidad de la columna, una vez que hubo regresión con el tratamiento clínico. Esta evolución nos lleva a concluir que la escoliosis idiopática de esta adolescente debe ser imputada como la única responsable del cuadro clínico de la paciente, y que la fusión de los arcos costales no interfiere en la biomecánica de la columna vertebral. Nivel de Evidencia: IV. Tipo de estudio: Serie de caso.

Staged Nasal Reconstruction Using a Forehead Flap and Rib Bone and Cartilage Graft in a Binder Syndrome Patient: A Case Report

Binder syndrome is a rare maxillofacial abnormality. Yet, once presented, it often needs to be addressed surgically. To suit this purpose, various surgical techniques have been developed. This paper is a case report of a staged nasal reconstruction in a Binder syndrome patient using rib bone and cartilage graft and forehead flap. At the same time, preoperative and postoperative anthropomorphometric measurements were compared to assess the efficiency of the proposed surgical technique.

Moenkhausia lepidura (Kner, 1858) (Characiformes, Characidae): osteology and relationships / Moenkhausia lepidura (Kner, 1858) (Characiformes, Characidae): osteologia e relações de parentesco

Abstract Cladistic analysis of fishes are mostly based on osteological studies. Phylogenetic relationships within the family Characidae are poorly known in part due to the lack of anatomical studies of its members, including osteology. The present contribution aims to offer a detailed description of all bony complexes of Moenkhausia lepidura. Two remarkable morphological conditions present in the species are discussed: a bony lamella on the proximal portion of the ribs and a basal expansion of the gill rakers. A morphological survey of several species of Characidae along with available phylogenetic information of the family indicates the putative relationships of Moenkhausia lepidura with other small characids presenting bony lamella on ribs and a dark mark on the caudal fin.

Resumo Análises cladísticas morfológicas de peixes são, em grande parte, baseadas em estudos osteológicos. As relações filogenéticas em Characidae são pouco conhecidas, em parte devido à falta de estudos anatômicos de seus representantes, incluindo a osteologia. O presente estudo tem por objetivo oferecer uma descrição detalhada dos complexos ósseos de Moenkhausia lepidura. Duas condições morfológicas notáveis presentes na espécie são discutidas: uma lamela óssea na porção proximal das costelas e uma expansão basal dos rastros branquiais. Um estudo morfológico de diversas espécies de Characidae, juntamente com informações filogenéticas disponíveis na família, indica a possível relação de M. lepidura com pequenos caracídeos que apresentam lamelas ósseas nas costelas e marcas escuras na nadadeira caudal.

Rib's strapping-traction technology combined with memory-alloy ribs embracing fixator for multiple rib fractures under video-assisted thoracoscope / 中华创伤杂志

Objective To investigate the clinical efficacy of rib's strapping-traction technology using absorbable implants combined with memory-alloy ribs embracing fixator in treating multiple rib fractures under video-assisted thoracoscope.Methods A retrospective case control study was performed to analyze 178 patients with multiple rib fractures treated from January 2015 to June 2017.According to the operation method,all patients were divided into observation group (91 patients) and control group (87 patients).The observation group including 59 males and 32 females aged (39.7 ± 7.8)years adopted internal fixation by rib's strapping-traction technology using absorbable implants combined with memory alloy ribs embracing fixator under video-assisted thoracoscopic surgery.The control group including 56 males and 31 females aged (40.2 ± 6.9) years adopted internal fixation by conventional rib's clamping-traction technology using towel forcep combined with memory-alloy ribs embracing fixator under video-assisted thoracoscopic surgery.The incision length,single rib internal fixation time,number of internal fixation rib fractures,visual analogue scale (VAS) score on postoperative 1 d,postoperative chest drainage,postoperative hospital stay,and postoperative fracture healing were compared between the two groups.Results All patients were followed up for 3-30 months (mean,16.7 months).All operations were successful,with no case of thoracotomy.The observation group had shorter incision length [(4.3 ± 1.2) cm vs.(6.2 ± 1.7) cm] and single rib internal fixation time [(10.3±2.9)min vs.(14.1 ±2.3)min] than the control group (P＜0.05).There were no significant differences (P ＞ 0.05) between the two groups in number of internal fixation rib fractures [(5.7±.3.6) vs.(5.9±3.3)],postoperative chest drainage [(668.3 ±131.4)ml vs.(703.7±116.2)ml],postoperative hospital stay [(6.4 ± 1.8) d vs.(6.8 ± 1.7) d],the VAS score on postoperative 1 d [0-3 point,62％ vs.61％;4-6 point,38％ vs.39％],postoperative osteophyte formation rate [postoperative 1 month,97％ vs.95％;postoperative 3 months,100％ vs.100％].Stable chest walls and thoracic deformity recovery were seen in all patients,with no significant complications occurred.Conclusion Rib's strapping-traction technology using absorbable implants combined with memory-alloy ribs embracing fixator under video-assisted thoracoscope is convenient and has exact efficacy for multiple rib fractures,with advantage of shorter incision length and operation time over conventional thoracoscopic surgery,and thus is worthy of clinical application.

Bilateral First Rib Stress Fractures with Pseudoarthrosis in a Young Weightlifter: A Rare Cause of Shoulder Pain / 대한스포츠의학회지

Isolated stress fracture of the first rib is quite rare cause of uncertain shoulder pain in athletes. These fractures are stress induced and precipitated by repeated traction of muscles acting on the first rib. A prompt diagnosis can shorten the time required for healing and decrease the risk of associated complication as nonunion or pseudoarthrosis. The diagnosis can be made by taking a thorough history and performing chest X-ray, computed tomography, or bone scan. Early recognition and proper management generally lead to successful outcomes and return to normal activities. Typically, they heal with conservative treatment with rest and mild analgesia. This report describes stress fractures of bilateral first rib in a weightlifter, one of which developed into a pseudoarthrosis as a result of persistent overhead activities due to missed diagnosis.

Minimally invasive surgery in patients with multiple fractured ribs complicated with traumatic diaphragmatic hernia / 中国内镜杂志

Objective To explore the effect of minimally invasive surgery in patients with multiple fractured ribs complicated with traumatic diaphragmatic hernia. Methods Clinical data of 48 patients with multiple fractured ribs complicated with traumatic diaphragmatic hernia from January 2010 to January 2016 were retrospective analyzed. All the patients were divided into control group and observation group according to the operation method, 24 cases in each. Patients in control group were treated with thoracotomy, while patients in observation group were treated by video-assisted thoracic surgery. Results The incision length, operative time, blood loss, postoperative thoracic drainage time and hospital stay in the observation group were significantly lower than that in control group, and the difference was statistically significant (P < 0.05). Patients with fractured ribs of the two groups were cured after bandage fixation and the observation group were treated with no conversion to thoracotomy. Clinical efficiency of the two groups were 91.67% and 79.16% and the overall complication rate was 8.32% and 37.48% respectively, the difference is statistically significant (P < 0.05). Conclusion The video-assisted thoracic surgery in treatment of multiple fractured ribs complicated with traumatic diaphragmatic hernia has advantages of less trauma and blood loss during operation, shorter operation time, faster postoperative recovery, and better curative effect, lower incidence of complications. It can be further promoted and used in clinical.

Digital measurement of anatomical parameters associated with vertebral units fixed by ribs and pedicle fixation of T4-T10 / 中华创伤骨科杂志

Objective To perform digital 3D measurement of anatomic parameters associated with vertebral units fixed by ribs and pedicle fixation of T4-T10,providing evidence for clinical application.Methods Spiral CT scan of T4-T10 vertebrae was conducted in 15 normal adults without spinal disorder.The data were imported into computer to establish units and disc models of thoracic and rib vertebrae T4-T10 using Mimics 16.0 software and Ansys 11.0 finite element software.The following data were measured in the vertebral pedicle-rib unit fixation group (group A) by software:transverse diameter of vertebral pedicle-rib unit,length of the outside pedicle screw,inclination angle of pedicle screw,and maximum and minimum inclination angles of pedicle screw;the following data were also measured in the pedicle fixation group (group B) by software:pedicle transverse diameter,length of pedicle screw,inclination angle of pedicle screw,and maximum and minimum inclination angles of pedicle screw.The corresponding parameters were compared between groups A and B.Results In both groups,the transverse diameters and screw lengths gradually increased with the increase in the vertebral sequence while the inclination angle of pedicle screw,and maximum and minimum inclination angles of pedicle screw decreased with the increase in the vertebral sequence.All the parameters in groups A were significantly larger than the corresponding ones in group B (P ＜ 0.05).Conclusions Of the spinal segment of T4-T10,the rib vertebral unit fixation can provide greater safe screw angles and screw diameters for clinical surgery.This is of vital significance for reducing the surgical complexity and improving screw prehension.

Value of imaging in the diagnosing echinococcosis of ribs / 中华放射学杂志

[Absract] Objective To investigate the imaging features of CT and MRI of echinococcosis, and improve the imaging knowledge of the disease. Methods Clinical and radiological findings of echinococcosis of ribs were retrospectively analyzed by reviewing the seventeen cases confirmed by clinical and pathological findings. All patients had CT scan, eight had X?ray plain film and five had MR examination, while 4 patients underwent additional contrast?enhanced CT examination. Results All lesions were unilateral. There were 33 ribs involved, and single involved rib was seen in 7 cases. On CT scans, 10 cases showed cystic, swelling and osteolytic bone destruction, and 7 cases showed moth?eaten osteolytic bone destruction. There were 13 cases of hydatid cyst, 3 cases of a single sac watery density shadow and 10 cases of polycystic separating wheels form. There were 4 cases of fractured ribs, 2 cases of the longitudinal fracture and 2 cases of the transverse fracture. On MRI, there was one case of rib medullary cavity expansion destruction. It was a single cyst with hypointensity on T1WI, hyperintensity on T2WI and hyperintensity on short time inversion recovery (STIR) images. There were one case of rib medullary cavity expansion destruction and 3 cases of hydatid erosion ribs cortex among 4 cases of polycystic type. Polycystic type echinococcosis appeared hypointensity on T1WI, hyperintensity on T2WI and hyperintensity on STIR images. Polycystic type had mother sac and ascus structure, and signal intensity of ascus was higher. STIR sequence showed more clearly polycystic structure. Conclusions CT and MRI can clearly show location of echinococcosis of ribs. There are the imaging features of cystic, swelling and osteolytic bone destruction or complicating cyst of polycystic type which can help the qualitative diagnosis of rib echinococcosis.
