Os tumores de parede torácicas são relativamente inusitados, representando 1 a 2% de todas as neoplasias, e cerca de 5% das neoplasias torácicas. Sarcomas são tumores raros e com apresentação heterogênea. São divididos em dois grandes grupos: tumores ósseos e de partes moles. A ocorrência na parede torácica é rara, representando 8% de todos os sarcomas. O tratamento de escolha é a ressecção com margens ampliadas e, quando ocorre a invasão de estruturas profundas, a toracectomia é indicada. A reconstrução do arcabouço ósseo é realizada com materiais de síntese, proporcionando estabilidade, e é seguida da reconstrução de partes moles com retalhos musculares, musculocutâneos ou locais ao acaso. Os tumores malignos primários da parede torácica correspondem a menos de 1% de todas as neoplasias e incluem grande variedade de lesões ósseas e de tecidos moles. Os condrossarcomas representam 20% dos tumores primários da parede torácica, sendo que 80% têm origem nas costelas e 20% no esterno.
Chest wall tumors are relatively uncommon, representing 1 to 2% of all neoplasms, and approximately 5% of thoracic neoplasms. Sarcomas are rare tumors with heterogeneous presentation. They are divided into two large groups: bone and soft tissue tumors. Occurrence in the chest wall is rare, representing 8% of all sarcomas. The treatment of choice is resection with wide margins and, when invasion of deep structures occurs, thoracotomy is indicated. The reconstruction of the bone framework is carried out with synthetic materials, providing stability, and is followed by the reconstruction of soft tissues with muscular, musculocutaneous, or random local flaps. Primary malignant tumors of the chest wall account for less than 1% of all neoplasms and include a wide variety of bone and soft tissue lesions. Chondrosarcomas represent 20% of primary tumors of the chest wall, with 80% originating in the ribs and 20% in the sternum.

Background: Unstable sternal fixation following sternotomy is one of the risk factors that affects postoperative outcomes in cardio-thoracic surgery and is associated with increased risk of infection, bleeding and delayed rehabilitation due to pain associated with sternal movement. Sternal plate systems, which help stabilize fixation, has been limited in use due to patients' comorbidities, such as diabetes mellitus (DM) and obesity. The conventional wire sternal-fixation procedure, which depend on years of physician' experience, raise concerns such as unstable sternal fixation due to uncompleted wire twisting. Therefore, a novel sternal-fixation procedure using both titanium cable and a PLA mesh plate was investigated as a potential improvement for sternal closure. We compared the ability of this new sternum fixation procedure (group N) against the conventional sternal fixation procedure using only a wire (group O) to achieve more stable postoperative sternal fixation. Methods and Results: Among adult open-heart surgeries performed between August 2020 and April 2023, 155 patients who underwent postoperative CT were included, with group N being the combined group and group O being the group using conventional metal wires: group N (86 patients: M 65, F 21) and group O (69 patients: M 50, F 19). Preoperative factors included age at surgery (group N: group O)=68.4±10.6 : 69.6±11.5 years (p=0.25)), BMI (group N: group O=23.0±3.7 : 24.1±7.7 (p=0.16)) and HbA1c (group N: group O=6.3±1.1 : 8.0±10.3% (p=0.10), and no factors were significantly different between the two groups. The CT analysis at the point of hospital discharge after surgery measured postoperative sternal deviation in the third rib position. Transverse displacement was significantly reduced (group N: group O=0.22±0.73: 0.83±1.08 mm (p=0.005)), and longitudinal displacement also showed an improvement but the difference was not statistically significant (group N: group O=0.53±0.86: 0.72±1.14 mm (p=0.13). Conclusion: A novel sternum closing technique using a tension-anchored titanium cable and a PLA mesh plate demonstrated improved postoperative sternal fixation in a controlled study with 155 patients. This new procedure also enables standardized stable sternal closure with a constant force without relying on conventional empirical sensation and without suppressing sternal cutting, thus contributing to the improvement of postoperative quality of life and prevention of complications.

La osteomielitis primaria de esternón es muy infrecuente en niños, con menos de 100 casos publicados hasta la actualidad. Su presentación clínica es a menudo inespecífica, lo que causa un retraso en el diagnóstico. Se presentan dos nuevos casos de osteomielitis primaria de esternón. Ambos referían un cuadro de fiebre, malestar general, dolor torácico y rechazo del decúbito, con eritema preesternal en uno de los casos. La velocidad de sedimentación globular y la proteína C-reactiva estaban elevadas en ambos casos. El diagnóstico se confirmó mediante estudios de imagen y en un caso se aisló Staphylococcus aureus sensible a meticilina en el hemocultivo. Ambos se recuperaron sin complicaciones con tratamiento antibiótico. Debe tenerse en cuenta la osteomielitis primaria de esternón en el diagnóstico diferencial del dolor torácico, especialmente si se acompaña de fiebre, signos inflamatorios locales, intolerancia al decúbito o elevación de reactantes de fase aguda.
Primary sternal osteomyelitis is very rare in children, with less than 100 cases published to date. Its clinical presentation is often non-specific, which results in a diagnostic delay. Here we describe 2 new cases of primary sternal osteomyelitis. Both referred fever, malaise, chest pain, and refusal to lie down, with pre-sternal erythema in one of the cases. The erythrocyte sedimentation rate and C-reactive protein values were high in both cases. The diagnosis was confirmed by imaging studies; methicillin-sensitive Staphylococcus aureus was isolated in the blood culture of one of them. Both recovered without complications with antibiotic treatment. Primary sternal osteomyelitis should be considered in the differential diagnosis of chest pain, especially if accompanied by fever, local inflammatory signs, intolerance to lying down, or increased acute phase reactants.

ABSTRACT Introduction: In this study, it was aimed to compare the clinical results and complications of rigid titanium plate reinforcement and only conventional wire methods for sternum fixation in morbidly obese patients who underwent sternotomy for open-heart surgery. Methods: The study was planned as a retrospective case-control study. Morbidly obese patients who underwent open-heart surgery with median sternotomy between 2011 and 2021 were analyzed retrospectively. Results: There was no statistically significant difference between the two groups in terms of characteristics of the patients (P≥0.05). Sternal dehiscence, sternum revision, wound drainage, and mediastinitis were significantly less common in the titanium plate group (P≤0.05). There was no statistically significant difference between the groups in terms of 30-day mortality (P≥0.05). Conclusion: Rigid titanium plate reinforcement application produced more positive clinical results than only conventional wire application. In addition, it was determined that although the rigid titanium plate application prolonged the operation time, it did not make a significant difference in terms of mortality and morbidity compared to the conventional wire applied group.

SUMMARY OBJECTIVE: The aim of this study was to investigate the relationship between the development of deep sternal wound infection after open heart surgery and inflammatory parameters obtained from routine biochemical tests. METHODS: A total of 280 patients who underwent cardiac surgery with median sternotomy between January 2015 and January 2020 were examined retrospectively. Patients who developed deep sternal wound infection were identified as "Group 1," and those who did not develop deep sternal wound infection were identified as "Group 2." RESULTS: There were 70 patients with a mean age of 61.6±9.9 years in Group 1 and 210 patients with a mean age of 62.7±9.8 years in Group 2. As a result of the analysis, it was found that the presence of concomitant chronic obstructive pulmonary disease, concomitant diabetes mellitus, blood and blood product transfusion, postoperative 2nd day C-reactive protein, postoperative 1st day neutrophil-to-lymphocyte ratio, and delta neutrophil-to-lymphocyte ratio was found as independent predictive factors of postoperative deep sternal wound infection development (p=0.043, p=0.012, p=0.029, p=0.009, p=0.002, and p<0.001; respectively). As a predictor of deep sternal wound infections development, postoperative 1st day neutrophil-to-lymphocyte ratio cutoff value was 11.2 (area under the curve [AUC] 0.598; p=0.014; 60% sensitivity, and 65.2% specificity), and delta neutrophil-to-lymphocyte ratio cutoff value was 9.6 (AUC 0.716; p<0.001; 57.1% sensitivity, and 73.8% specificity). CONCLUSIONS: Deep sternal wound infection development can be predicted with inflammatory parameters such as neutrophil-to-lymphocyte ratio and C-reactive protein that are obtained from cheap and easily available routine biochemical tests.

Abstract Objective: To examine the relationship that the types and locations of fractures of the sternum have with mortality and morbidity. Materials and Methods: We analyzed the records of 115 patients diagnosed with fracture of the sternum, due to blunt trauma, between 2007 and 2018. Records of computed tomography studies were obtained from the radiology archive of a tertiary teaching hospital. The type of fracture was classified as linear, displaced, or comminuted, whereas the fracture location was classified as the manubrium, body, or xiphoid process. Results: A total of 108 patients were included in the study. Of those patients, 92 (85.2%) were male and 16 (14.8%) were female. The etiology was a traffic accident in 72 cases (62.6%) and a fall from height in 36 (31.3%). The mean age was 42.1 ± 17.7 years for males and 53.9 ± 20.0 years for females. The mortality rate was 11.1%. Among the 12 deceased patients, the mean age was 44.4 ± 18.3 years. The fracture was located exclusively in the manubrium in 64 patients (59.3%), exclusively in the body of the sternum in 41 (38.0%), and in both locations in three (2.7%), whereas none were located in the xiphoid process. Morbidity rates were higher in the patients with fractures of the manubrium than in those with fractures of the body of the sternum, as was the incidence of accompanying bone fractures and organ injuries. The fracture was linear in 44 patients (40.7%), displaced in 62 (57.4%), and comminuted in 30 (27.8%). The mortality was significantly higher for comminuted fractures than for the other fracture types (p = 0.045; β = 4.40). Conclusion: Fracture of the manubrium can be indicative of the severity of trauma and has a poor prognosis.
Resumo Objetivo: Examinar a relação entre o tipo e a localização da fratura de esterno com mortalidade e morbidade. Materiais e Métodos: Foram analisados os prontuários de 115 pacientes com diagnóstico de fratura de esterno por trauma contuso entre 2007 e 2018. Os registros de estudos de tomografia computadorizada foram obtidos do arquivo de radiologia de um hospital universitário terciário. O tipo de fratura foi classificado como linear, deslocado ou cominutivo, enquanto o local da fratura foi classificado como no manúbrio, no corpo ou no processo xifoide. Resultados: Cento e oito pacientes foram incluídos no estudo. Desses, 92 (85,2%) eram do sexo masculino e 16 (14,8%) eram do sexo feminino. As causas foram acidente de trânsito em 72 casos (62,6%) e queda de altura em 36 (31,3%). A média de idade foi de 42,1 ± 17,7 anos para os homens e de 53,9 ± 20,0 anos para as mulheres. A taxa de mortalidade foi de 11,1%. Entre os 12 pacientes que faleceram, a média de idade foi de 44,4 ± 18,3 anos. A fratura localizou-se apenas no manúbrio em 64 pacientes (59,3%), somente no corpo do esterno em 41 (38,0%) e em ambas as localizações em três pacientes (2,7%), e nenhuma ocorreu no apêndice xifoide. As taxas de morbidade foram maiores nos pacientes com fraturas no manúbrio do que nos com fraturas no corpo do esterno, assim como a incidência de fraturas ósseas e lesões de órgãos adjacentes. A fratura foi linear em 44 pacientes (40,7%), deslocada em 62 (57,4%) e cominutiva em 30 (27,8%). A mortalidade foi significativamente maior nos casos de fraturas cominutivas do que em outros tipos de fratura (p = 0,045; β = 4,40). Conclusão: A fratura do manúbrio pode ser um indicativo da gravidade do trauma e de mau prognóstico.

Abstract Introduction: The objective of this study was to identify risk factors for deep sternal wound infection (DSWI) after off-pump coronary artery bypass (OPCAB) grafting surgery. Methods: A total of 8,442 patients undergoing OPCAB from April 1, 2009 to December 31, 2018 were retrospectively analyzed. A total of 956 were eventually enrolled on this study based on our exclusion criteria. All subjects were divided into two groups: group 1 (n=63) - DSWI; group 2 (n=893) - without DSWI. Patients were excluded if they had one of the following: acute coronary syndrome, conversion to OPCAB grafting surgery, redo procedure, concomitant cardiac surgery procedures. Results: The prevalence of body mass index (BMI) ≥40 kg/m2 (7.9% vs. 1.9%, respectively; P=0.01), lower extremity atherosclerotic artery disease (23.8% vs. 7.2%, respectively; P=0.001) and use of bilateral internal thoracic artery (19.5% vs. 2.5%, respectively; P=0.008) was significantly higher in patients with DSWI. The incidence of morbidities, including reoperation for bleeding (26.4% vs. 2.1%, respectively; P<0.001), stroke (4.8% vs. 0.8%, respectively; P=0.02), acute renal failure (7.9% vs. 0.8%, respectively; P=0.001), delirium (7.9% vs. 1.7%, respectively; P=0.008) and blood transfusion (30.6% vs. 9.8%, respectively; P<0.001) was significantly higher in patients with DSWI. Conclusions: A BMI of >40 kg/m2, lower extremity artery disease, use of bilateral internal thoracic artery (BITA) graft, postoperative stroke, sepsis, reoperation due to postoperative complications and blood product requirement significantly increased the risk of sternal infection after OPCAB.

OBJECTIVES@#To find the appropriate method for age estimation for different ages and sexes.@*METHODS@#The costal cartilage, sternum and pubic symphysis of 91 unknowns from 2000 to 2020 from the Forensic Department of the Criminal Investigation Team of Shanghai Public Security Bureau were collected. Costal cartilage, sternal and pubic symphysis inferences were used to estimate the age, and the consistency between the estimated results and the actual physiological age of the unknowns was tested. The accuracy of age estimation of different samples was compared, and the relationship between accuracy and age and sex was analyzed.@*RESULTS@#Using the costal cartilage method, the inference errors of males, females and the whole population under 40 years old were (0.608±2.298) years, (0.429±1.867) years and (0.493±2.040) years, while those over 40 years old were (-1.707±3.770) years, (-3.286±4.078) years and (-2.625±4.029) years. The differences between different age groups in these three populations were statistically significant (P<0.05). Using the sternum method, the inference errors of males and females under the age of 40 were (0.921±3.019) years and (0.452±1.451) years, while those over the age of 40 were (-5.903±5.088) years and (-1.429±2.227) years. The differences between different age groups in males and females were statistically significant (P<0.05). Using the pubic symphysis method, the inference errors of males and females under 40 years old were (-0.204±1.876) years and (0.238±2.477) years, while those over 40 years old were (1.500±2.156) years and (-2.643±4.270) years. The differences between different age groups in males and females were statistically significant (P<0.05). Using the sternum method and pubic symphysis method for age estimation of over 40 years old, the difference between different sexes was statistically significant (P<0.05).@*CONCLUSIONS@#All three methods of age estimation are stable and effective and more accurate for people under 40 years old. For age estimation of unknowns over 40 years old, the pubic symphysis method is preferred in males and the sternum method is preferred in females.

ABSTRACT Objective: To evaluate the sagittal tomographic reformatting of the sternum using unpublished radiographic parameters (indexes and angles), comparing them between the different types of pectus, and controls. Methods: 44 patients with pectus deformities and controls underwent chest CT for analysis. The types of pectus were classified into: inferior pectus carinatum (IPC), superior (SPC) and lateral (LPC), and broad (BPE) and localized pectus excavatum (LPE). The following tomographic parameters were created and measured: (1) spine-manubrium-sternum index (SMS); (2) column-sternum index (CSI); (3) manubrium-sternal angle (MSA); (4) inferior manubrium angle (IMA); and (5) inferior sternum angle (ISA). Statistical analysis was performed between the pectus and control groups, and between the different types of pectus. Results: There was a significant difference between: a) pectus excavatum and pectus carinatum when analyzing the SMS, CSI, MSA and ISA indexes. b) LPE and control group for SMS and ISA. c) LPC and LPE, and LPC and BPE for SMS; d) BPE and LPC for CSI; e) IPC and LPE, and IPC and BPE for ISA; f) SPC and LPE, and SPC and BPE for IMA. Conclusion: The radiographic indexes and angles created provided differentiation parameters between patients with different types of pectus, and between these and controls.

RESUMO O pectus excavatum é considerado uma patologia da parede torácica, onde há convexidade no aspecto ventral do esterno, o que gera complicações secundárias, como alongamento ventrodorsal do tórax e aumento da pressão intratorácica, entre outras. No presente caso, o corpo de um cachorro Buldogue Francês nasceu com sinais prévios de decaimento e baixo consumo de leito materno, além de uma avaliação médica forense. De acordo com a avaliação patológica, foi encontrada uma fenda no peito esternal relacionada às esternas caudais próximas à cartilagem xifóide, conteúdo espumoso na cartilagem epiglótica da laringe e sinais graves de enfisema nos lobos caudal, craniano e médio pulmonar. Na avaliação cardiológica, foi observada assimetria morfológica invaginante no septo interventricular na mesma área em que a fenda esternal ocorre, por sua vez, na avaliação radiográfica, evidencia uma depressão dorsal do terço caudal do esterno com alterações consideráveis na silhueta cardíaca. Na Colômbia não há relatos de ninhadas completas que apresentem esta alteração, portanto, pretende-se que este seja o primeiro relatório anatomopatológico e de imagem que descreva a patologia em caninos.
ABSTRACT Pectus excavatum is considered a pathology of the chest wall where there is convexity in the ventral aspect of the sternum, which generates secondary complications, such as ventrodorsal stretching of the chest and increased intrathoracic pressure, among others. In the present case, the body of a French bulldog dog was born with previous signs of decay and low consumption of maternal waste, in addition to a forensic medical evaluation. According to the pathological evaluation, a crack was found in the sternal chest related to the caudal sternum close to the xiphoid cartilage, frothy content in the laryngeal epiglottis cartilage and severe signs of emphysema in the caudal, cranial and middle lung lobes. In the cardiological evaluation, an invaginating morphological asymmetry was observed in the interventricular septum in the same area in which the sternal cleft occurs, in turn, in the radiographic evaluation, it shows a dorsal depression of the caudal third of the sternum with considerable changes in the cardiac silhouette. In Colombia there are no reports of complete litters that present this alteration, so it is intended that this is the first anatomopathological and imaging report that describes the pathology in canines.

Abstract Introduction: In this study, we aimed to evaluate the anatomical deformations of the major vascular structures in the retrosternal area caused by adhesions following coronary artery bypass grafting (CABG). Methods: This single-center, retrospective study included a total of 40 patients with a previous CABG who were admitted to our emergency unit for any reason and underwent a contrast-enhanced chest computed tomography (patient group) and 40 patients without previous cardiac surgery (control group) between January 2018 and November 2019. The retrosternal area was compared between the groups using the statistical shape analysis method. The distance between the sternum and the ascending aorta and pulmonary artery was measured and anatomical deformations of the retrosternal area were examined. Results: There was a statistically significant difference in the anatomical structures of the retrosternal area between the patient and control groups (P<0.001). The distance from the midsternal line to the highest point of the pulmonary artery was statistically significantly shorter in the patient group, compared to the control group (P=0.013). The distance from the sternum to the ascending aorta was also shorter in the patient group, although it did not reach statistical significance (P>0.05). Conclusions: Our study results showed narrowing of the retrosternal area following CABG and a shorter distance from the sternum to the pulmonary artery than the ascending aorta. Based on these findings, surgeons should be cautious about possible injuries in patients requiring cardiac surgery with repeated median sternotomy.

Abstract Introduction: Use of bilateral internal thoracic artery (BITA) as graft in coronary artery bypass grafting (CABG) is controversial because it is related to higher in-hospital mortality, incidence of sternal wound-related infection, and an increase in surgical time. The primary objective of this study is to evaluate in-hospital mortality and mortality within 30 days from discharge. The secondary objective is to evaluate the occurrence of deep sternal wound infection in a 90-day follow-up. Methods: This is a retrospective review of the medical records of 152 patients undergoing elective CABG with the use of BITA and cardiopulmonary bypass (CPB). These patients were divided into two groups, diabetics and non-diabetics. Patients with acute myocardial infarction and concomitant valvular disease were not included in the sample. Results: Preoperative characteristics did not show significant differences between the groups, which allowed a comparative analysis. The variables electrocardiography time and aortic clamping time were higher in the diabetic group, with a significant statistical difference (P<0.0001). In-hospital mortality occurred in three patients, and there was no mortality up to 30 days in both groups. There was no significant difference in the primary end point between groups (P=0.56). Deep sternal wound infection was present in only one patient and showed no significant difference in the secondary outcome between groups (P=0.40). Conclusion: We did not observe a higher mortality and occurrence of deep sternal wound infection with the use of BITA in diabetic patients compared to non-diabetics, even with greater CPB and aortic clamping times in diabetics.

Primary malignant giant cell tumor (PMGCT) is a diagnosis based on the presence of a high-grade sarcomatous component along with a typical benign giant cell tumor (GCT). We report the first case of PMGCT of the sternum in a 28-year-old male with painless swelling over the manubrium sterni. The differential diagnoses of PMGCT and giant cell-rich osteosarcoma were considered. Surgical resection was performed, and the reconstruction was done with a neosternum using polymethyl methacrylate and prolene mesh. At 30 months follow-up, the patient is disease-free.

SUMMARY: The purpose of this research is to determine a regression equation for estimation of stature from length of sternum measurements. This research was carried out on 1001 subjects (504 male and 497 female) among the population of Montenegrin adolescents. The stature and length of sternum measurements were taken according to the ISAK protocol, and the data were analyzed statistically. Linear regression analysis determined the prediction of and length of sternum on the criterion variable a body height at the significance level of p <0.05. These relations are presented in the form of scatter diagram. Thereby, we obtained the coefficient of determination, the multiple correlation coefficients, the partial correlation coefficient, the regression, t-test and standardized beta coefficient. The results of this research study confirmed that length of sternum reliably predicts stature in both sexes of Montenegrin adolescents and revealed a very useful finding for physical anthropologists and experts from related fields. It was confirmed that there is a correlation between length of sternum and body height (males: 33.1 %, females: 31.3 %). Therefore, length of sternum has proven to be a reliable predictor on the basis of which the actual body height can be estimated.
RESUMEN: El propósito de este estudio fue determinar una ecuación de regresión para la estimación de la estatura a partir de la longitud del esternón. El análisis se llevó a cabo en 1001 sujetos (504 hombres y 497 mujeres) entre la población de adolescentes montenegrinos. Se tomaron medidas de la estatura y la longitud del esternón de acuerdo con el protocolo ISAK, y los datos se analizaron estadísticamente. El análisis de regresión lineal determinó la predicción y la longitud del esternón en la variable de criterio de la altura del cuerpo con nivel de significancia de p <0,05. Las relaciones se presentan en forma de diagrama de dispersión. De este modo, obtuvimos el coeficiente de determinación, los coeficientes de correlación múltiple, el coeficiente de correlación parcial, la regresión, la prueba t y el coeficiente beta estandarizado. Los resultados de este estudio confirmaron que la longitud del esternón logra predecir la estatura en ambos sexos de adolescents montenegrinos de manera confiable, y reveló un hallazgo útil para los antropólogos físicos y los expertos de áreas relacionadas. Se confirmó que existe una correlación entre la longitud del esternón y la altura del cuerpo (hombres: 33,1 %, mujeres: 31,3 %). Por lo tanto, la longitud del esternón ha demostrado ser un predictor confiable sobre la base de la cual se puede estimar la altura real del cuerpo.

Sternal fractures are not frequent. There are not many case reports and nowadays, there is not an agreement regarding their treatment. The aim of this report is to present a case in order to contribute clarifying the existing therapeutic proposals. A case of a 45 years-old male patient, who consults because of pain in the anterior region of the chest after a traffic accident is analyzed. The images studies reveal an sternal fracture on the upper third. A surgical approach is proposed but, as the patient refuses it, an ambulatory treatment is made with a satisfactory evolution. Although a surgical treatment was not done, the non surgical management achieved satisfactory results
