Temporomandibular disorder (TMD) is recognized for its high prevalence, presenting characteristic signs and symptoms. Cervical spine pain is present in 70% of diagnosed TMD cases. Aim To verify if women with TMD present changes in isometric muscle strength in the scapula elevation. Methods This is an observational, cross-sectional study. Thirty-five women, aged 22.89±2.04 years, were divided into the TMD group (TMDG), diagnosed with TMD according to the DC/TMD, and control group (CG), with asymptomatic individuals. The volunteers accessed a online link by the smartphone in order to answer questions on personal data, the Fonseca Anamnestic Index (FAI), Neck Disability Index (NDI), and Masticatory preference. In all participants, evaluation of the force of the scapula elevation muscles was performed, using a load cell model MM-100 (Kratos® SP, Brazil). Data were analyzed descriptively using the maximum, mean, and standard deviation and a two-way ANCOVA test was applied for all variables. A significance level of 5% was considered. Results There were no statistically significant differences between the TMDG and CG for the maximal and mean muscle strength of scapular elevation. There were statistically significant differences in FAI (p <0.001*) between the CG and the TMDG. Conclusion Based on the results, it was not possible to confirm the hypothesis that women diagnosed with TMD present lower isometric strength during scapular elevation (right/left).

Abstract Objective To study the anatomy of the medial coracoclavicular ligament and assess the contribution of the acromioclavicular, coracoclavicular and medial coracoclavicular ligaments to the stability of the acromioclavicular joint. Methods Twenty-six shoulders from 16 fresh cadavers were dissected after placement in dorsal recumbency with a 15-cm cushion between the shoulder blades. An extended deltopectoral approach was performed proximally and medially, followed by plane dissection and ligament identification. The acromioclavicular and coracoclavicular distances were measured using points previously marked with a millimeter caliper. Six of these specimens were submitted to a biomechanical study. The acromioclavicular ligament, the coracoclavicular ligament and the medial coracoclavicular ligament were sectioned sequentially, and a cephalic force of 20 N was applied to the lateral clavicle. The acromioclavicular and coracoclavicular distances were measured in each of the ligament section stages. Results The right medial coracoclavicular ligament presented, on average, 48.9 mm in length and 18.3 mm in width. On the left side, its mean length was 48.65 mm, with a mean width of 17.3 mm. Acromioclavicular, coracoclavicular and medial coracoclavicular ligament section resulted in a statistically significant increase in the coracoclavicular distance and posterior scapular displacement. Conclusion The medial coracoclavicular ligament is a true ligamentous structure found in all dissected shoulders. Our results showed that the scapular protraction relaxed the medial coracoclavicular ligament, while scapular retraction tensioned it; in addition, our findings demonstrate that this ligament contributes to the vertical and horizontal stability of the acromioclavicular joint.

Resumo Objetivo Estudar a anatomia do ligamento coracoclavicular medial e avaliar a contribuição do ligamento acromioclavicular, coracoclaviculares e coracoclavicular medial na estabilidade da articulação acromioclavicular. Métodos Foram dissecados 26 ombros de 16 cadáveres frescos, posicionados em decúbito dorso-horizontal, com um coxim de 15 cm de altura entre as escápulas. Realizou-se uma via deltopeitoral estendida proximal e medialmente. Realizou-se dissecção por planos e identificação dos ligamentos. Realizou a medida da distância acromio-clavicular e coracoclavicular usando pontos previamente demarcados com paquímetro milimetrado. Em seis dessas amostras foi realizado estudo biomecânico. Seccionando, nesta ordem, o ligamento acromioclavicular, os coracoclaviculares e o ligamento coracoclavicular medial com uma força cefálica de 20N foi aplicada na clavícula lateral. Foi medida a distância acromio-clavicular e coracoclavicular em cada uma das etapas de secção dos ligamentos. Resultados A média de comprimento do ligamento coracoclavicular medial foi de 48,9mm e a média de largura, de 18,3mm no lado direito. No esquerdo, a média de comprimento foi de 48,65mm e a média da largura, 17,3mm. Após a secção dos ligamentos acromioclaviculares, coracoclaviculares, com a secção do ligamento coracoclavicular medial houve aumento estatisticamente significativo da distância córaco-clavicular e um deslocamento posterior da escápula. Conclusão O ligamento coracoclavicular medial é uma estrutura ligamentar verdadeira, presente em todos os ombros dissecados. Nossos resultados demonstraram que o ligamento coracoclavicular medial encontra-se relaxado com a escápula em protração e tenso com a escápula em retração e segundo nossos resultados participa tanto da estabilidade vertical quanto da estabilidade horizontal da articulação acromioclavicular.

Introduction: curved and hooked acromia play a key role in shoulder impingement syndrome. Little is known about acromial type in the Brazilian population. Aim: To describe the acromial profile of Brazilian young adults; to evaluate its correlation with gender and handedness and the occurrence of symmetry between the genders. Methodology: forty acromia in 20 Brazilian adults of both genders, aged 21-25 years, were studied. The acromial type was classified through the Bigliani/Epstein method using radiographs in supraspinatus outlet view. Results: as there was no gender difference in occurrences of acromial type, we considered the male and female groups together. Thus, among the 20 right acromia, we found 5 type I (25%), 8 type II (40%) and 7 type III (35%). Among the 20 left acromia, we found 4 type I (20%), 11 type II (55%) and 5 type III (25%). The only left-handed volunteer (100%) presented acromial type III in both the right and the left shoulder. Among the 19 right-handed volunteers, 5 (26.3%) presented right acromion type I, 8 (42.1%) had type II and 6 (31.6%) had type III; for the left acromion, 4 (21.1%) presented type I, 11 (57.9%) had type II and 4 (21.1%) had type III. Acromial symmetry occurred in 60% of females and 70% of males. Conclusion: type II acromion was predominant, in both the right and the left shoulder in Brazilian young adults. There was no correlation between acromial type and gender. It was not possible to analyze the correlation between acromial type and handedness. Acromial type tended to be symmetrical in our sample.

Introdução: o acrômio curvo e gancho desempenham um papel fundamental na Síndrome do impacto do ombro. Pouco se sabe sobre o tipo acromial na população brasileira. Objetivo: descrever o perfil do tipo acromial em adultos jovens brasileiros e avaliar sua correlação com o gênero e a lateralidade e a ocorrência de simetria entre os sexos. Metodologia: foram estudados 40 acrômios de 20 adultos brasileiros, de ambos os sexos, com idade entre 21 e 25 anos. O tipo acromial foi classificado pelo método de Bigliani/ Epstein nas radiografias de perfil de escápula. Resultados: como não houve diferença na ocorrência do tipo acromial quanto ao gênero, consideramos os grupos masculino e feminino juntos. Assim, dos 20 acrômios direitos, foram encontrados 5 (25%) do tipo I, 8 (40%) do tipo II e 7 (35%) do tipo III, enquanto que dos 20 acrômios esquerdos, foram encontrados 4 (20%) tipo I, 11 (55%) tipo II e 5 (25%) tipo III. O único voluntário canhoto (100%) apresentou para o ombro direito e esquerdo o tipo acromial III. Dos 19 voluntários destros, 5 (26,3%) apresentavam acrômio direito tipo I, 8 (42,1%) tipo II e 6 (31,6%) tipo III; para o acrômio esquerdo, 4 (21,1%) apresentavam tipo I, 11 (57,9%) tipo II e 4 (21,1%) tipo III. A simetria acromial ocorreu nos grupos feminino (60%) e masculino (70%). Conclusão: o acrômio tipo II foi o mais predominante para os ombros direito e esquerdo em adultos jovens brasileiros. Não houve correlação entre o tipo de acromial e o gênero. Não foi possível analisar a correlação entre o tipo acromial e a lateralidade. O tipo acromial tende a ser simétrico em na amostra estudada.

El osteocondroma es un tumor óseo benigno que afecta, en general, a niños y adultos jóvenes. Se localiza habitualmente en las metáfisis de los huesos largos alrededor de la rodilla, aunque también puede afectar a huesos planos como la escápula.Se presenta el caso clínico de un niño de 11 años con tumoración dolorosa en la superficie dorsal de la escápula de un año de evolución. Se diagnostica un osteocondroma escapular, localización poco frecuente para este tumor. Debido a la persistencia de la sintomatología, se realizó exéresis quirúrgica

Osteochondroma is a benign bone tumor that usually affects children and young adults. It is typically located in the metaphysis of long bones around the knee, although it could also affect flat bones like scapula. We report the case of a 11-year-old child with one year of evolution painful tumor at the dorsal surface of the scapula. He was diagnosed with osteochondroma of the scapula, uncommon location for this tumor. Due to the persistence of the symptomatology surgical excision was performed.

Abstract Simple bone cysts rarely occur in the scapula, and, to our knowledge, they have not been reported in the acromion. In the present report, we present the case of a 24-year-old female patient who was successfully treated by curettage and grafting using xenografting. No recurrence findings were observed during the follow-up six months postoperatively, the patient had recovered full range of motion, and she was able to perform all routine activities satisfactorily.

Resumo Cistos ósseos simples são raros na escápula, e, pelo que sabemos, não foram relatados no acrômio. Aqui, apresentamos uma paciente do sexo feminino, de 24 anos, submetida com sucesso ao tratamento composto por curetagem e xenoenxerto. Não foram observados achados de recidiva no acompanhamento pós-operatório de seis meses, quando a paciente apresentou amplitude total de movimento e foi capaz de realizar todas as atividades rotineiras de maneira satisfatória.

INTRODUÇÃO: As unidades de cuidados neonatais dispõem de altos recursos tecnológicos que, aliados ao avanço da ciência, visam garantir a sobrevida de recém-nascidos (RNs). Entretanto, o internamento expõe os RNs a variados estímulos que, associados a assistência inadequada, podem favorecer o surgimento de alterações posturais. OBJETIVO: Investigar a frequência dos sinais sugestivos de retração de cintura escapular em RNs que necessitaram de internamento. MATERIAIS E MÉTODOS: Estudo observacional, quantitativo e longitudinal, realizado com 16 RNs, internados na Unidade de Cuidados Intermediários (UCI) de um hospital estadual, localizado na cidade de cidade de Salvador, Bahia, no ano de 2019. Os dados foram coletados por meio de medidas das escápulas, sinal do cachecol, protocolo de inspeção biomecânica e prontuários. RESULTADOS: Sete (43,7%) RNs apresentaram sinais sugestivos de retração de cintura escapular. Seis (37,5%) apresentaram sinal do cachecol positivo e apenas um (6,3%) apresentou simultaneamente os sinais de abdução de membros superiores, adução escapular, sinal do cachecol positivo e redução das medidas das escápulas em relação à coluna ao longo do internamento. A comparação entre a diferença do maior e do menor valor das medidas das escápulas, com o sinal do cachecol, não foi estatisticamente significante. Porém, aqueles que apresentaram sinal do cachecol positivo e/ou diminuição das medidas atingiram valores máximos de dias de internamento. CONCLUSÃO: Os sinais sugestivos de retração de cintura escapular estiveram presentes em quase metade da amostra. Importante salientar que esses achados traduzem as características específicas da população do estudo, considerando suas limitações.

INTRODUCTION: Neonatal care units have high technological resources that, together with the advancement of science, aim to ensure the survival of newborns (NBs). However, hospitalization exposes newborns to various stimuli that, associated with inadequate care, can favor the appearance of postural changes. OBJECTIVE: To investigate the frequency of signs suggestive of scapular waist retraction in newborns who required hospitalization. Materials and METHODS: Observational, quantitative, and longitudinal study, carried out with 16 newborns, admitted to the Intermediate Care Unit (ICU) of a state hospital, located in the city of Salvador, Bahia, in the year 2019. Data were collected through scapula measurements, scarf signs, biomechanical inspection protocol, and medical records. RESULTS: Seven (43.7%) of the newborns showed signs suggestive of scapular waist retraction. Six (37.5%) showed a positive scarf sign and only one (6.3%) simultaneously showed signs of the abduction of the upper limbs, scapular adduction, positive scarf sign, and reduced scapular measurements in relation to the spine along with hospitalization. The comparison between the difference between the highest and lowest scapular measurements, with the scarf sign, was not statistically significant. However, those who showed a positive scarf sign and/or reduced measurements reached maximum values for days of hospitalization. CONCLUSION: Signs suggestive of scapular waist retraction were present in almost half of the sample. It is important to note that these findings reflect the characteristics of the study population, considering their limitations.

The incidence of posterior instability of shoulder joint was significantly lower than that of anterior instability, but the clinical diagnosis and treatment was difficult, and the misdiagnosis and missed diagnosis rate were high. Its etiology, clinical manifestation and treatment strategy are totally different from the anterior instability. Therefore, the deep understanding of the anatomical structure around the shoulder joint, the mastery of the examination method, and the classification of the shoulder instability based on the anatomy and injury mode are of great importance to improve the accuracy of diagnosis. CT three-dimensional reconstruction is helpful to evaluate the defect of humeral head and glenoid bone, and MRA is helpful for the accurate diagnosis of posterior glenoid lip and joint capsule. The treatment was divided into conservative treatment and surgical treatment. Conservative treatment is recommended for muscular instability. Surgical treatment is recommended for traumatic and dysplastic instability. Different operative methods should be performed according to the injury of glenoid side or humeral head side. According to the condition of bone defect, soft tissue operation, bone grafting or osteotomy were performed to reconstruct the posterior stable structure of the glenoid injury; according to the area of the anterior bone defect, bone grafting or subscapular muscle packing were performed to the head of humerus defect. The former has the advantages of short learning curve and firm fixation, while the latter has the advantages of minimally invasive operation and the ability to observe the lesions from multiple angles and accurately control the location of bone masses. This paper summarizes the above problems.

The surgical treatment of recurrent anterior shoulder dislocation is a difficult problem in the field of sports injury medicine. The main reason focus on dynamic and osseous constraints of shoulder joint could not recover well. At present, arthroscopic surgery is used at home and abroad, and could receive statisfied postoperative effect, but the choice of specific surgical methods is still controversial. According to presence and size of glenoid and humeral skull defects, different treatments should be selected in clinic. The author recommends that no articular glenoid defect or glenoid defect 40% or Bristow-Latarjet if the surgical repair fails, bone grafting is used. In addition, if (humeral avulsion of glenohumeral ligaments, HAGL) injury existed, HAGL injury repair should be used. In addition to considering the important factor of bone defects, it is necessary to combine patient's age, exercise level and surgeon's technique to comprehensively select the bestsurgical method.

Resumen: La luxación glenohumeral recurrente suele asociarse a pérdida ósea de la porción glenoidea, siendo la localización anteroinferior la más afectada. El entendimiento de las estructuras relacionadas así como el uso de estudios de imagen actuales tales como la tomografía axial computarizada y la resonancia magnética han permitido avanzar respecto a la comprensión de la patología, asimismo el desarrollo de materiales quirúrgicos y herramientas de mínima invasión nos permiten continuar innovando respecto a los tratamientos previamente descritos, siendo posible intervenir en detalles técnicos con la intención de mejorar los resultados. Es por eso que hemos realizado lo descrito por Eden-Hybinette utilizando injerto tricortical cadavérico con tornillos canulados como método de fijación, limitando las comorbilidades asociadas a la toma de autoinjerto, dando como resultado un amplio beneficio para el paciente durante el procedimiento quirúrgico y en el período de recuperación.

Abstract: Recurrent glenohumeral dislocation is usually associated with bone loss of the glenoid portion, with the anteroinferior location being the most affected. The understanding of the related structures, as well as the use of current imaging studies such as computed axial tomography and magnetic resonance imaging, have made progress in understanding the pathology, as well as the development of surgical materials and minimally invasive tools, they allow us to continue innovating with respect to the previously described treatments, being possible to intervene in technical details with the intention of improving the results. That is why we have done what described by Eden-Hybinette, using tricortical cadaveric graft and as fixation method, limiting the comorbidities associated with the autograft taking, resulting a wide benefit for the patient, during the surgical procedure and in the recovery period.

Abstract Objective The objective of this paper was to identify safety parameters in the posterior surgical approach of the scapula through a cross-sectional cadaver study. Methods Thirteen cadaver shoulders with no history of surgery or prior musculoskeletal dysfunction, with mean age, weight, and height of 70.1 years, 61.5 kg, and 1.64 m, respectively, were dissected. The anatomic landmark of the studied pathway (infraglenoid tubercle) and its distance to the axillary and suprascapular nerves were measured. Results The mean distance between the infraglenoid tubercle (IT) and the axillary nerve (AN) was 23.8 mm, and the mean distance from the IT to the suprascapular nerve (SN) was 33.2 mm. Conclusion The posterior approach may be considered safe through the interval between the infraspinatus and teres minor. However, caution should be taken during muscle spacing because of the short distance between the fracture site and the location of the SN and AN. These precautions help to avoid major postoperative complications.

Resumo Objetivo O presente trabalho teve como objetivo identificar parâmetros de segurança para a realização da via de acesso cirúrgico posterior da escápula por meio de um estudo transversal em cadáveres. Métodos Foram dissecados 13 ombros de cadáveres sem história de cirurgia ou disfunção musculoesquelética prévia e em bom estado de conservação, com médias de idade, peso e altura de 70,1 anos, 61,5 kg, 1,64m, respectivamente. Identificou-se marco anatômico da via estudada (tubérculo infraglenoidal) e sua distância para os nervos axilar e supraescapular foi medida. Resultados A distância média encontrada entre o tubérculo infraglenoidal (TI) e o nervo axilar (NA) foi de 23,8 mm e distância média do TI ao nervo supraescapular (NSE) foi de 33,2 mm. Conclusão A via posterior pelo intervalo entre os músculos infraespinal e redondo menor é considerada segura; porém, é preciso atenção e cautela durante o afastamento muscular, devido à curta distância média entre o sítio de fratura e a localização do NSE e do NA. Tais precauções podem evitar maiores complicações pós-operatórias.

El tratamiento quirúrgico del cáncer de mama puede dejar secuelas tardías tales como escápula alada, pérdida de movilidad articular del hombro, sobrepeso, etc. Basado en lo anterior, el objetivo del presente estudio fue describir las secuelas morfofuncionales en mujeres operadas de cáncer de mama de las regiones de la Araucanía y del Bío-Bío, Chile, explorando también si el procedimiento quirúrgico conllevaría a la presencia de escápula alada. Para ello, se realizó un estudio cuantitativo, observacional y de corte transversal en treinta mujeres operadas de cáncer de mama, de edades comprendidas entre 28 y 76 años (55,67±11,60). Un profesional entrenado evaluó peso, estatura, índice de masa corporal (IMC), índice de cintura cadera (ICC), rangos articulares de hombro (ROM, Range of Movement) y fuerza prensil, aplicándose además la prueba de Hoppenfeld para identificar escápula alada. Los resultados mostraron diferencias significativas en el ROM a la abducción de hombro (p<0,05), correlación significativa positiva de leve (r=0,370) a moderada (r=0,514) entre el ROM del lado afectado tanto para la flexión como la abducción con la fuerza prensil. Destacan, un IMC de 28,91±5,31 kg/m2, un ICC de 0,86±0,06 cm y la presencia de escápula alada en el 36,7 % de las participantes. No se encontró asociación entre el abordaje quirúrgico y la presencia de escápula alada. Hubo secuelas morfo-funcionales en las mujeres en estudio, destacándose las alteraciones en el rango de movimiento del miembro superior, sobrepeso, riesgo cardiovascular y la presencia de escápula alada, sin asociarse al tipo de abordaje quirúrgico.

Surgical treatment of breast cancer can leave late sequelae such as winged scapula, loss of joint mobility of the shoulder, overweight, etc. Based on the above, the objective of the present study was to describe the morpho-functional sequelae in women operated on for breast cancer from the regions of Araucanía and Del BíoBío, Chile, also exploring whether the surgical procedure would lead to the presence of scapula winged. For this, a quantitative, observational and cross-sectional study was conducted in thirty women operated on for breast cancer, aged between 28 and 76 years (55.67 ± 11.60). A trained professional evaluated weight, height, body mass index (BMI), hip waist index (ICC), shoulder joint ranges(ROM, Range of Movement) and prehensile strength, and applied the Hoppenfeld test to identify the winged scapula. The results showed significant differences in the ROM to shoulder abduction (p <0.05), positive significant correlation of mild (r = 0.370) to moderate (r = 0.514) between the ROM of the affected side for both flexion and abduction with prehensile force. Highlights, a BMI of 28.91 ± 5.31 kg / m2, an ICC of 0.86 ± 0.06 cm and the presence of winged scapula in 36.7 % of the participants. No association was found between the surgical approach and the presence of the winged scapula. There were morphofunctional sequelae in the women under study, highlighting the alterations in the range of movement of the upper limb, overweight, cardiovascular risk and the presence of the winged scapula, without being associated with the type of surgical approach.

SUMMARY: The suprascapular artery (SSA) has been identified to be of clinical relevance to clavicular fracture, suprascapular neuropathy and surgical intervention of shoulder. Thus its origin and course have been intensively studied. In this case, we found a unilateral variation of the suprascapular artery, originating from the 1st segment of axillary artery, and sequentially penetrating the upper trunk of brachial plexus, passing through the suprascapular notch under the superior transverse scapular ligament. This case will be helpful to clinical management in cervical and shoulder region.

RESUMEN: Se ha identificado que la arteria supraescapular (ASS) tiene relevancia clínica en la fractura clavicular, la neuropatía supraescapular y la intervención quirúrgica del hombro. En consecuencia, su origen y su curso han sido ampliamente estudiados. En este caso, encontramos una variación unilateral de la arteria supraescapular, originada en el primer segmento de la arteria axilar, y que penetraba secuencialmente en el tronco superior del plexo braquial, pasando a través de la incisura supraescapular debajo del ligamento escapular transverso superior. Este caso será útil para el manejo clínico en la región cervical y del hombro.

Resumen: Introducción: Las fracturas escapulares comprenden 1% del total de las fracturas en general y de 3 a 5% del hombro, las cuales se presentan por alta energía en pacientes jóvenes. Sólo 10% tiene indicación quirúrgica al tomarse como base la alteración de complejo suspensorio del hombro. El objetivo es valorar el resultado de pacientes con indicación quirúrgica así como una revisión de la literatura. Reporte de casos: Presentamos dos pacientes con fractura del cuerpo escapular derecho Bartonicek D con desplazamiento mediolateral, deformidad angular anteroposterior y alteración del ángulo glenopolar. Se realizó el manejo quirúrgico con osteosíntesis y placas convencionales y anatómicas. Se realizó valoración funcional y seguimiento radiográfico de ambos casos a los seis meses y se obtuvo arcos de movilidad flexión 180o/170o en ambos casos, así como escalas funcionales DASH 22/25, Constant 90/89 y Simple Shoulder Test 11/11 respectivamente; se obtuvo una consolidación ósea grado III-IV de Montoya. Discusión: Se considera importante realizar una adecuada reducción y estabilización del trazo de fractura debido al bajo grado de satisfacción con tratamiento conservador en pacientes con alta demanda funcional, que consiste en dolor residual, pinzamiento y disquinesia escapular. Se recomienda la cirugía para estas fracturas ya que comprometen la cadena cinética del hombro e impactan en el resultado funcional a corto y mediano plazo.

Abstract: Introduction: Scapular fractures comprise 1% of all fractures and 3 to 5% of the shoulder, they occur in young patients by high energy trauma. Only 10% have surgical indication based on the alteration of the shoulder's suspensory complex. The objective is to assess the outcome of patients with surgical indication as well as a review of the literature. Case report: We present two patients with Bartonicek D fracture of the right scapular body with mediolateral displacement, anteroposterior angular deformity and alteration of the glenopolar angle. Surgery was performed on both cases with conventional and special anatomical plates. Functional assessment and radiographic follow-up of both cases were performed at 6 months, obtaining flexion mobility of 180º/170º in both cases, as well as functional scales DASH 22/25, Constant 90/89 and Simple Shoulder Test 11/11 respectively; with bone consolidation grade III-IV of Montoya. Discussion: Due to the low degree of satisfaction with conservative treatment in patients with high functional demand, and multiple complications consisting in residual pain, impingement and scapular dyskinesia; it is important to perform an adequate reduction and stabilization of the fracture. We recommend surgical management for this type of fractures since they compromise the kinetic chain of the shoulder and impact the functional outcome in the short and medium term.

ABSTRACT Objective: To evaluate the chest wall shape in patients with adolescent idiopathic scoliosis (AIS) in comparison to healthy subjects and the association between the chest wall shape with the spine deformity and lung function in patients with AIS. Methods: This cross-sectional study enrolled 30 AIS patients and 20 healthy subjects aged 11-18 years old. The Cobb angle evaluation was performed in AIS patients. The chest wall shape was assessed by the photogrammetry method, using the Postural Assessment Software (PAS). We created thoracic markers shaped as angles (A) and distances (D), as follows: A2 (right acromion/xiphoid/left acromion), A4L (angle formed between the outer point of the smallest waist circumference and its upper and lower edges on the left side), A7 (angle formed by the intersection of the tangent segments of the upper and lower scapulae angles), D1R/D1L [distance between the xiphoid process and the last false rib on the right (R) and left (L) sides], and D3 (distance between xiphoid process and anterior superior iliac spine). Results: The thoracic markers A2 and A7 were significantly higher, while the A4L and D1R/D1L were significantly reduced in the AIS group compared to the control. Moderate correlations were found between: A2 and the main and proximal thoracic Cobb angles (r=0.50, r=0.47, respectively); D1R/D1L and the main thoracic Cobb angle (r=- 0.40); and the forced expiratory volume in the first second (FEV1) and D3R (r=0.47). Conclusions: The photogrammetry method was able to detect chest wall changes in AIS patients, besides presenting correlation between Cobb angles and lung function.

RESUMO Objetivo: Avaliar o formato da caixa torácica em pacientes com escoliose idiopática do adolescente (EIA), comparando-os com indivíduos saudáveis e analisar a associação do formato da caixa torácica com a deformidade da coluna vertebral e função pulmonar em pacientes com EIA. Métodos: Estudo transversal que avaliou 30 pacientes com EIA e 20 indivíduos saudáveis com idade entre 11 e 18 anos. O ângulo de Cobb foi avaliado em pacientes com EIA. O formato da caixa torácica foi analisado pelo método da fotogrametria, utilizando o Software para Avaliação Postural (SAPO). Foram criados marcadores torácicos descritos como ângulos (A)e distâncias (D): A2 (acrômio direito/processo xifoide/acrômio esquerdo), A4E (ângulo formado entre o ponto externo da menor circunferência da cintura e suas bordas superior e inferior do lado esquerdo), A7 (ângulo formado pela interseção das retas tangentes aos ângulos superior e inferior das escápulas), D1D/D1E [distância entre o processo xifoide e a última costela falsa nos lados direito (D) e esquerdo (E)] e D3 (distância entre o processo xifoide e a espinha ilíaca anterossuperior). Resultados: Os marcadores torácicos A2 e A7 foram significativamente maiores, enquanto o A4E e o D1D/D1E foram significativamente menores no grupo EIA em relação ao controle. Foram encontradas correlações moderadas entre: A2 e os ângulos de Cobb torácico principal e proximal (r=0,50 e r=0,47, respectivamente); D1D/D1E e o ângulo de Cobb torácico principal (r=-0,40); e o volume expiratório forçado no primeiro segundo (VEF1) e D3D (r=0,47). Conclusões: O método da fotogrametria detectou alterações na caixa torácica de pacientes com EIA, além de apresentar correlações significativas entre os ângulos de Cobb e a função pulmonar.

PURPOSE: This study investigated the effects of shoulder protraction exercise according to weight by examining the surface electromyography (EMG) amplitude in the serratus anterior (SA), upper trapezius (UT), and pectoralis major (PM) as well as the activity ratio of each muscle. METHODS: Twenty three winging scapula subjects participated in the study. The subjects performed scapula protraction at shoulder 90° flexion and 60° horizontal abduction with up to four (none, 1kg, 1.5kg, and 2kg) dumbbells in the supine position. The EMG data were collected from the dominant side muscles during a shoulder protraction exercise according to weight in the supine position. One way repeated measures analysis of variance (ANOVA) was used to compare the normalized activities of the SA, UT, and PM and the ratios of PM/SA and UT/SA. RESULTS: The results showed that the activities of both the SA and UT were highest for the shoulder protraction exercise at 2kg in the supine position. The UT/SA ratio also was the lowest for exercise at 2kg. On the other hand, the activities of both the UT and PM/SA ratio were similar under all conditions. CONCLUSION: These results show that there is a need to selectively strengthen the SA muscle in the case of patients with the shoulder dysfunction. In particular, it is necessary to weigh 2kg when performing shoulder protraction exercises in the supine position to activate the SA muscle in patients with a winging scapula.

Klippel-Feil syndrome is characterized by congenital fusion of two or more cervical vertebrae, a low hair line at the back of the head, restricted neck mobility, and other congenital anomalies. We report a 16-year-old young man with Klippel-Feil syndrome, Sprengel deformity of the right scapula, thoracic kyphoscoliosis, and mandibular prognathism with an anterior open bite. He was treated with orthodontic treatment and maxillofacial surgery. An anticipated difficult airway due to a short neck with restricted neck movements and extrinsic restrictive lung disease due to severe thoracic kyphoscoliosis increased his anesthesia risk. Due to his deviated nasal septum and contralateral inferior turbinate hypertrophy, we chose awake fiber optic orotracheal intubation followed by submental intubation. Considering the cervical vertebral fusion, he was carefully positioned during surgery to avoid potential spinal injury. He recovered well and his postoperative course was uneventful.

Acromial fractures are well-documented complications subsequent to reverse shoulder arthroplasty (RSA), and most appear as stress fractures with no history of single trauma. To date, no study has reported the occurrence of acute displaced acromial fracture due to sudden strong deltoid contraction during heavy work. Displacement of the fracture results in a challenging surgery since it is difficult to obtain adequate fixation in thin and osteoporotic bones. We report a rare case of acute displaced acromial fracture after successful RSA treatment, using a novel technique of open reduction and internal fixation, applying two 4.5 mm cannulated screws and lateral clavicle precontoured plate.
