Medial condyle hypoplasia in adolescent and young adult patients with trochlear dysplasia: a retrospective study / Hipoplasia do côndilo medial em pacientes adolescentes e adultos jovens com displasia troclear: estudo retrospectivo

Abstract Objective: To determine the association between medial femoral condyle hypoplasia and trochlear dysplasia by analyzing the knee magnetic resonance imaging scans of young patients with or without trochlear dysplasia. Materials and Methods: This was a retrospective analysis of magnetic resonance imaging scans of the knees of young individuals (16-35 years of age): 30 patients with trochlear dysplasia and 30 individuals with no signs of patellofemoral instability. The ratios between the depth, width, and height of the medial and lateral femoral condyles (dLC/dMC, wLC/wMC, and hLC/hMC, respectively) were calculated, as was the ratio between the width of the medial condyle and the total width of the femur (wMC/FW). All of the values were determined in consensus by two radiologists. Results: We evaluated 60 patients: 30 with trochlear dysplasia and 30 without. The mean dLC/dMC, wLC/wMC, and hLC/hMC ratios were higher in the patients than in the controls (p < 0.05), whereas the mean wMC/FW ratio was lower in the patients (p < 0.05). The optimal cutoff values, obtained by calculating the areas under the receiver operating characteristic curves, were 1.0465 for the dLC/dMC ratio (76% sensitivity and 63.3% specificity), 0.958 for the wLC/wMC ratio (80% sensitivity and 73.3% specificity), and 1.080 for the hLC/hMC ratio (93.3% sensitivity and 93.3% specificity). Conclusion: Our findings confirm our hypothesis that trochlear dysplasia is associated with medial condyle hypoplasia.

Resumo Objetivo: Determinar a associação entre hipoplasia do côndilo femoral medial e displasia troclear mediante análise de ressonância magnética do joelho de pacientes jovens com displasia troclear e sem displasia troclear. Materiais e Métodos: Análise retrospectiva de exames de ressonância magnética de joelhos de indivíduos jovens (16 a 35 anos de idade), sendo 30 pacientes com displasia troclear e 30 indivíduos sem sinais de instabilidade femoropatelar. As razões entre a profundidade, largura e altura dos côndilos femorais mediais e laterais (dLC/dMC, wLC/wMC e hLC/hMC, respectivamente) foram calculadas, assim como a razão entre a largura do côndilo medial e a largura total do fêmur (wMC/FW). Todos os valores foram determinados em consenso por dois radiologistas Resultados: Foram incluídos no estudo 60 adolescentes e adultos jovens, 30 com displasia troclear e 30 sem displasia troclear. A média das razões dLC/dMC, wLC/wMC, hLC/hMC foi maior nos pacientes do que nos controles (p < 0,05), enquanto a média da razão wMC/FW foi menor nos pacientes (p < 0,05). Os valores de corte ótimos obtidos da área sob a curva característica de operação do receptor foram 1,0465 para dLC/dMC (sensibilidade de 76% e especificidade de 63,3%), 0,958 para wLC/wMC (sensibilidade de 80% e especificidade de 73,3%) e 1,080 para hLC/hMC (sensibilidade de 93,3% e especificidade de 93,3%). Conclusão: Nossos resultados confirmam nossa hipótese de que a displasia troclear está associada a hipoplasia do côndilo medial.

Epithelial ingrowth under LASIK flaps: tips and tricks for preventing recurrence!

Background: LASIK for refractive error correction has become a universal surgery. Despite its popularity, the estimated prevalence of traumatic flap dislocations in post?LASIK patients is 3.9%, and it is sometimes associated with epithelial ingrowth. The prognosis in such cases depends on the rapid surgical revision of the flap with the removal of the EI and perioperative steps to prevent Epithelial ingrowth (EI) recurrence in the future. Purpose: The video aims to display the steps involved in revising the flap, removing EI, and tips to prevent its recurrence. Synopsis: A 33?year?old post? LASIK patient presented with decreased vision, photophobia, and glare during the COVID pandemic in the right eye for 2 months. The best?corrected visual acuity was reduced to 6/60. The anterior segment revealed traumatic flap dislocation along with macro fold temporally and epithelial ingrowth. She underwent a successful flap revision surgery with no recurrence of epithelial ingrowth postoperatively. Highlights: A successful revision of a 2?month? old traumatic folded flap was performed along with the complete removal of EI. It explains the step?by?step approach to avoid the recurrence of EI in each step of the surgical revision of the flap. The video is self?explanatory and guides novice surgeons too

Recurrent Anterior Shoulder Dislocation After Trauma with Coracoid Apophysis Fracture - A Rare Association / Luxação anterior recorrente do ombro após traumatismo com fratura apófise coracoide - Uma associação rara

Abstract Anterior dislocations represent about 96% of total shoulder dislocations, with recurrence/instability being more common in young patients. Injury of other shoulder structures is frequent, namely bony Bankart lesion. However, the association with coracoid apophysis fracture is very rare. The present article describes the clinical case of a 67-year-old man who presented to the emergency department with complaints of persistent omalgia, with acute episodes, beginning after a fall from his own height. The patient also presented history of shoulder trauma 3 months earlier, which was evaluated at another hospital. Shoulder anterior dislocation was observed radiographically, and the computed tomography (CT) confirmed bone erosion of the anteroinferior part of the glenoid (bone loss of about 50% of the anteroposterior diameter in the lower region of the glenoid), with almost complete resorption of the bony Bankart lesion (apparent in later analysis of the radiography of the initial traumatic episode). Connectedly, a transverse fracture of the coracoid apophysis (type II in the Ogawa classification) was diagnosed. The patient was submitted to surgical treatment, with anterior bone stop confection using the remnant of the fractured fragment of the coracoid supplemented by tricortical autologous iliac graft, fixed with cannulated screws (according to the Bristow-Latarjet and Eden-Hybinett techniques). In the postoperative follow-up, a good functional result was observed, with no new episodes of dislocation and no significant pain complaints. A rare association of shoulder lesions is described, and the challenge of their treatment is highlighted, given the late diagnosis, as in the case presented.

Resumo As luxações anteriores representam cerca de 96% do total de luxações do ombro, sendo a recidiva/instabilidade mais comum em pacientes jovens. A lesão de outras estruturas do ombro é frequente, nomeadamente a lesão óssea de Bankart. Contudo, a associação com a fratura da apófise coracoide é muito rara. Este artigo descreve o caso clínico de um homem de 67 anos que recorreu ao serviço de urgência com queixas de omalgia persistente, com episódios de agudização, iniciados após queda da própria altura. O paciente apresentava ainda histórico de trauma do ombro 3 meses antes, avaliado em outro hospital. A luxação anterior do ombro foi constatada radiograficamente, e a tomografia computorizada (TC) do ombro confirmou erosão óssea da vertente anteroinferior da glenoide (perda óssea de cerca de 50% do diâmetro anteroposterior na região inferior da glenoide), com reabsorção quase completa de lesão óssea de Bankart (aparente em análise a posteriori da radiografia do episódio traumático inicial). Associadamente, foi diagnosticada uma fratura transversa da apófise coracoide (tipo II da classificação de Ogawa). O paciente foi submetido ao tratamento cirúrgico, com confecção do batente ósseo anterior utilizando remanescente do fragmento fraturado do coracoide suplementado por enxerto autólogo tricortical do ilíaco, fixados com parafusos canulados (de acordo com as técnicas de Bristow-Latarjet e Eden-Hybinett). No seguimento pós-operatório, foi observado um bom resultado funcional, sem novos episódios de luxação e sem queixas álgicas significativas. Descreve-se uma associação rara de lesões do ombro, e salienta-se o desafio do tratamento das mesmas dado o seu diagnóstico tardio, como no caso apresentado.

Tratamiento ortésico de luxación de cadera derivada de osteomielitis del cuello del fémur. Presentación de dos casos

La osteomielitis es una inflamación ósea causada principalmente por bacterias. En los casos de osteomielitis del cuello del fémur y artritis séptica concomitante, las complicaciones pueden ocasionar, a largo plazo, acortamiento y deterioro articular considerables. Se describen los casos de dos pacientes neonatos, con manifestaciones de hipertermia como signo común; y solo en uno de ellos limitación del movimiento del miembro inferior derecho, contractura en flexión y aducción, dolorosa a la movilización. El diagnóstico se basó en criterios clínicos, imagenológicos y de laboratorio. El tratamiento consistió en el uso de la férula en abducción, lo cual garantizó la reducción concéntrica de la cabeza del fémur en la cavidad acetabular; esto pudo constatarse mediante seguimiento y control de la reducción, a través de radiografía simple de la pelvis en cada consulta. El diagnóstico precoz de la enfermedad determina el empleo de un tratamiento más conservador, además de minimizar la aparición de complicaciones.

Osteomyelitis is a bone inflammation caused mainly by bacteria. In cases of the femur's neck osteomyelitis and concomitant septic arthritis, complications can lead to considerable joint shortening and deterioration in the long term. The cases of two neonatal patients are described, with hyperthermia manifestations as a common sign; and only in one of them limited movement of the right lower limb, flexion and adduction contracture, painful on movement. The diagnosis was based on clinical, imaging and laboratory criteria. The treatment consisted in the use of the abduction splint, which guaranteed the concentric reduction of the femoral head in the acetabular cavity; this could be verified by monitoring and control of the reduction, through simple radiography of the pelvis in each consultation. The early diagnosis of the disease determines the use of a more conservative treatment, in addition to minimizing complications.

Evaluation of Clinical & Functional Outcomes Bristow Latarjet Procedure in the Management of Recurrent Anterior Shoulder Dislocation

Background: Glenohumeral joint is highly susceptible to dislocation due to its wide range of movements. Recurrent anterior shoulder dislocations are common in young adults. The Bristow Latarjet procedure is one of the effective techniques for the treatment of recurrent anterior shoulder dislocation. This study aimed to assess the clinical and functional outcome of the Bristow Latarjet procedure in the management of recurrent anterior shoulder dislocation. Material & Methods: This prospective interventional study was conducted in the Department of Orthopaedic Surgery, BSMMU, from October 2017 to September 2019. Within this period, a total of 40 cases of recurrent anterior shoulder dislocation that meet inclusion criteria were taken as a sample. Patients were evaluated both pre and postoperatively for functional outcomes according to Rowe’s score for instability. A purposive non-randomized sampling technique was used in this study. All the data were compiled and sorted properly and the quantitative data were analyzed statistically by using Statistical Package for Social Science (SPSS-25). The results were expressed as frequency, percentage and mean ± SD. Paired Student’s‘t’ test was performed to compare pre and final postoperative follow-up. The level of significance was calculated at a confidence interval of 95% and p-value <0.05. Results: : In this study age of the patient ranged from 18-40 years and the mean age was 28.2±6.3. 29(72.5). Surgery was done within 4-6 months of the first dislocation in 5 patients, within 6-12 months in 21 patients and after 12 months in 14 patients. The mean (±SD) Rowe score for instability was significantly (p<0.001) higher 6 months after the Bristow Latarjet procedure at 91.87(±9.00) in comparison to preoperative periods 52.62(±18.40). Results were excellent in 32(80%), good in 4(10%), fair in 3(7.5%) and poor in 1(2.5%) patients. 36(90%) patients were in the satisfactory group and only 4(10%) in the unsatisfactory group. Only 1(2.5%) patient developed screw migration, 2(5%) patients developed subluxation, and 1(2.5%) patient developed postoperative arthritis. Conclusion: It can be concluded that the Bristow-Latarjet procedure is a very effective and safe procedure with reduced complications, presenting very satisfactory functional results in the treatment of recurrent anterior shoulder dislocation.

Causes of late-presenting developmental dislocation of the hip beyond 12 months of age: A pilot study

Background & objectives: Developmental dysplasia of the hip (DDH), when detected early, can usually be managed effectively by simple methods. A delayed diagnosis often makes it a complex condition to treat. Late presentation of DDH is fairly common in developing countries, and there is scarcity of literature regarding the epidemiology and reason for late presentation. Through this study, we attempted to identify the reasons for late presentation of DDH in children more than 12 months of age. Methods: Fifty four children with typical DDH and frank dislocation of hip in whom treatment was delayed for 12 months or more were included. Parents were interviewed with a pre-structured questionnaire and data were collected for analysis with Microsoft Excel 2016 and SPSS version 26. Results: Diagnostic delay was the most common reason for late presentation and was observed in 52 children (96.2%). The mean age at diagnosis was 24.7 months. The mean age at treatment was 37.3 months with a mean delay of 12.5 months from diagnosis and 22.1 months from initial suspicion. Physician-related factors contributed 55.3 per cent, while family and social issues accounted for 44.7 per cent of overall reasons for diagnostic and treatment delays. Interpretation & conclusions: Late presentation of DDH in walking age is common. Physician- and family-related factors accounted for most of these cases. Failure or inadequate hip screening at birth by the attending physician is a common reason for late diagnosis. The family members were unaware about the disorder and developed suspicion once child started walking with an abnormal gait

Ultrasound techniques for the detection of developmental dysplasia of the hip: a systematic review and meta-analysis

ABSTRACT BACKGROUND: Developmental dysplasia of the hip (DDH) encompasses a broad spectrum of hip pathologies, including femoral or acetabular dysplasia, hip instability, or both. According to the medical literature, ultrasonography is the most reliable diagnostic method for DDH. Several techniques for the assessment of hips in newborns and infants, using ultrasonography, have been described. OBJECTIVE: To compare the accuracy of the Graf technique and other diagnostic techniques for DDH. DESIGN AND SETTING: A systematic review of studies that analyzed ultrasound techniques for the diagnosis of DDH within an evidence-based health program of a federal university in São Paulo (SP), Brazil. METHODS: A systematic search of relevant literature was conducted in the PubMed, EMBASE, Cochrane Library, CINAHL, and LILACS databases for articles published up to May 5, 2020, relating to studies evaluating the diagnostic accuracy of different ultrasound techniques for diagnosing DDH. The QUADAS 2 tool was used for methodological quality evaluation. RESULTS: All hips were analyzed using the Graf method as a reference standard. The Morin technique had the highest rate of sensitivity, at 81.12-89.47%. The Suzuki and Stress tests showed 100% specificity. The Harcke technique showed a sensibility of 18.21% and specificity of 99.32%. CONCLUSION: All the techniques demonstrated at least one rate (sensibility and specificity) lower than 90.00% when compared to the Graf method. The Morin technique, as evaluated in this systematic review, is recommended after the Graf method because it has the highest sensitivity, especially with the three-pattern classification of 89.47%.

Functional Shoulder Evaluation after Osteosynthesis of Greater Tuberosity Fracture: Is There any Influence of Glenohumeral Dislocation? / Avaliação funcional do ombro após osteossíntese da fratura da tuberosidade maior: Há influência da luxação glenoumeral?

Abstract Objective To evaluate the postoperative functional and radiographic outcomes of the shoulder of patients submitted to transosseous suturing of a greater tuberosity fracture (GTF) through an anterolateral route and the influence of the glenohumeral dislocation on these outcomes. Methods We conducted a retrospective study and functional assessment using the Constant-Murley score. The distance between the greater tuberosity and the joint surface of the proximal humerus (in true anteroposterior radiographs) after the union was calculated. We used the Fisher exact test for the categorical independent variables, and the Student t or Mann-Whitney test for the non-categorical variables. Results In total, 26 patients met the inclusion criteria, and 38% of the sample presented an association between glenohumeral dislocation and GTF. The mean Constant-Murley score was of 82.5 + 8.02 points. The presence of an associated dislocation did not alter the functional outcome. The mean distance between the greater tuberosity of the humerus and the joint surface of the humeral head after the union was of 9 + 4.3 mm below the articular line of the humeral head. The dislocation led to a lower level of reduction, but this did not influence the Constant-Murley score. Conclusion The cases of GTF submitted to surgical treatment with transosseous sutures had good functional outcomes. The presence of dislocation made the anatomical reduction of the greater tuberosity difficult. However, it did not influence the Constant-Murley score.

Resumo Objetivo Avaliar os resultados funcional e radiográfico pós-operatórios do ombro, em pacientes submetidos a sutura transóssea de fratura da tuberosidade maior (FTM) por acesso anterolateral, e a influência da luxação glenoumeral nesses resultados. Métodos Realizou-se estudo retrospectivo e avaliação funcional (pela escala de Constant-Murley). Calculou-se a distância entre a tuberosidade maior e a superfície articular do úmero proximal (por meio de radiografia em incidência anteroposterior verdadeira) após a consolidação. Usou-se o teste Exato de Fisher para as variáveis independentes categóricas, e os testes tde Student ou de Mann-Whitney para as não categóricas. Resultados Ao todo, 26 pacientes preencheram os critérios de inclusão. A associação de luxação glenoumeral com FTM foi observada em 38% da amostra. A média da pontuação na escala de Constant-Murley foi de 82,5 + 8,02. A presença de luxação associada não alterou o resultado funcional. A distância média da consolidação da tuberosidade maior do úmero em relação à superfície articular da cabeça umeral foi de 9 + 4,3 mm abaixo da linha articular da cabeça umeral. Pacientes com luxação associada evoluíram com redução menor, mas isso não influenciou na pontuação na escala de Constant-Murley. Conclusão As FTMs submetidas ao tratamento cirúrgico com sutura transóssea evoluíram com bom resultado funcional. A presença de luxação dificultou a redução anatômica da tuberosidade maior. Entretanto, isso não influenciou na pontuação na escala de Constant-Murley.

Multidirectional Instability in a Neglected Elbow Dislocation Managed with Circumferential Ligament Reconstruction. A Case Report / Instabilidade multidirecional em uma luxação negligenciada do cotovelo gerenciada com reconstrução do ligamento circunferencial. Um relato de caso

Abstract Neglected elbow dislocation is an uncommon condition and its treatment remains challenging. We present a case of a middle-aged woman presenting with neglected elbow dislocation and multi-direction instability in whom open reduction of the elbow joint and circumferential ligamentous reconstruction with a gracilis tendon graft was done. The functional outcome assessed with the Mayo elbow performance index was excellent. This circumferential technique is undoubtedly a viable technique and the indications can be extended to even manage a neglected dislocation. This procedure reduces the need or diminishes the duration of external fixation requirement and thereby encourages early mobilization.

Resumo A luxação negligenciada do cotovelo é uma condição incomum e seu tratamento permanece desafiador. Apresentamos o caso de uma mulher de meia-idade que apresentou luxação negligenciada do cotovelo e instabilidade multidirecional, na qual foi realizada redução aberta da articulação do cotovelo e reconstrução ligamentar circunferencial com enxerto de tendão gracilis. O resultado funcional avaliado com o índice de desempenho do cotovelo de Mayo foi excelente. Essa técnica circunferencial é, sem dúvida, uma técnica viável e as indicações podem ser estendidas para gerenciar até mesmo um deslocamento negligenciado. Este procedimento reduz a necessidade ou diminui a duração da exigência de fixação externa e, assim, incentiva a mobilização precoce.

Stress distribution in lower second molar mesialization using mini-implants: a pilot study using 3D finite element analysis / Distribuição de tensões na mesialização do segundo molar inferior usando mini-implantes: um estudo piloto usando análise de elementos finitos 3D

Objective: to analyze the stress distribution in a 3D model that simulates second molar mesialization using two different types of mini-implants. Material and Methods: a mandible bone model was obtained by recomposing a computed tomography performed by a software program. The cortical and trabecular bone, a lower second molar, periodontal ligament, orthodontic tube, resin cement and the mini-implants were designed and modeled using the Rhinoceros 4.0 software program. The characteristics of self-drilling orthodontic mini-implants were: one with 7 mm length, 1 mm transmucosal neck section and 1.6 mm diameter and another with 5 mm length and 1.5 mm diameter. A total of 235.161 and 224.505 elements were used for the mesh. These models were inserted into the bone block and then subjected to loads of 200 cN (centinewton). The results were calculated and analyzed by the Ansys 17.0 software program for qualitative verification through displacement and maximum principal stress maps. Results: it was possible to observe that the periodontal ligament presented low displacement and stress values. However, the physiological values presented are among those capable to provide orthodontic movement, with compression and tensile area visualization staggered between 0.1 and -0.1 MPa (megapascal). Conclusion: within the limitations of the study, the mini-implants tested showed similar results where the load on the tooth allowed dental displacement (molar mesialization), with a tendency to rotate it, theoretically allowing the second molar to take the location of the first molar. (AU)

Objetivo: analisar a distribuição de tensões em um modelo 3D que simula a mesialização do segundo molar usando dois tipos diferentes de mini-implantes. Material e Métodos: um modelo de osso mandibular foi obtido por recomposição de uma tomografia computadorizada realizada por um software. O osso cortical e trabecular, um segundo molar inferior, ligamento periodontal, tubo ortodôntico, cimento resinoso e os mini-implantes foram projetados e modelados no software Rhinoceros 4.0. As características dos mini-implantes ortodônticos auto perfurantes foram: um com 7 mm de comprimento, 1 mm de secção transmucosa e 1,6 mm de diâmetro e outro com 5 mm de comprimento e 1,5 mm de diâmetro. Para a malha, foram utilizados 235.161 e 224.505 elementos. Esses modelos foram inseridos no bloco ósseo e então submetidos a cargas de 200 cN (centinewton). Os resultados foram calculados e analisados pelo software Ansys 17.0 para verificação qualitativa por meio de mapas de deslocamento e tensões máximas principais. Resultados: foi possível observar que o ligamento periodontal apresentou baixos valores de deslocamento e tensões. Porém, os valores fisiológicos apresentados são capazes de proporcionar movimentação ortodôntica, com visualização da área de compressão e tração escalonada entre 0,1 e -0,1 MPa (megapascal). Conclusão: dentro das limitações do estudo, os mini-implantes testados apresentaram resultados semelhantes onde a carga sobre o dente permitiu o deslocamento dentário (mesialização do molar), com tendência a girá-lo, permitindo teoricamente que o segundo molar ocupe do lugar do primeiro molar (AU)

Treatment of recurrent anterior shoulder dislocation using the latarjet technique / Tratamento da luxação anterior recidivante do ombro pela técnica de latarjet

ABSTRACT Objective: To describe the functional results, recurrence rate, postoperative radiographic appearance, and complications of patients undergoing the Latarjet procedure over 24 months. Methods: Retrospective case series, including adult patients with recurrent traumatic anterior glenohumeral dislocation undergoing the Latarjet procedure. We clinically evaluated patients preoperatively by the Rowe score and at six, 12, and 24 months after the procedure. The positioning, consolidation, and resorption of the graft were analyzed by plain radiography. The recurrence rates and other complications were also described. Results: We analyzed 40 patients (41 shoulders). The Rowe score median increased from 25 before surgery to 95 at 24 months after surgery (p < 0.001). We observed graft resorption in three cases (7.3%) and consolidation in 39 (95.1%). Most grafts presented adequate placement. We observed two recurrences (4.8%), one case of dislocation and one of subluxation. Seven patients (17.1%) had a positive apprehension test. The study had no cases of infection, neuropraxia, or graft breakage. Conclusion: Latarjet surgery is a safe and effective procedure in the treatment of recurrent anterior dislocation of the shoulder. This surgery enables a statistically significant improvement according to the Rowe score, with a low number of recurrences. Level of Evidence IV, Case Series.

RESUMO Objetivo: Descrever os resultados funcionais, a taxa de recidiva, o aspecto radiográfico pós-operatório e as complicações de pacientes submetidos ao procedimento de Latarjet ao longo de 24 meses. Métodos: Série de casos retrospectiva que inclui pacientes adultos com luxação glenoumeral recidivante anterior traumática submetidos ao procedimento de Latarjet. Avaliamos clinicamente os pacientes pela escala de Rowe pré-operatória e aos 6, 12 e 24 meses após o procedimento. O posicionamento, a consolidação e a reabsorção do enxerto foram analisados por radiografia simples. Descrevemos ainda as taxas de recidiva e as demais complicações. Resultados: Analisamos 40 pacientes (41 ombros). A mediana da escala de Rowe evoluiu de 25,0 antes da cirurgia para 95,0 passados 24 meses desde a cirurgia (p < 0,001). Foi observada reabsorção do enxerto em três casos (7,3%), e consolidação em 39 (95,1%). A maioria dos enxertos apresentava posicionamento adequado. Ocorreram duas recidivas (4,8%), sendo um caso de luxação e outro de subluxação. Sete pacientes (17,1%) referiam sensação de apreensão. Não ocorreram casos de infecção, neuropraxia ou quebra do enxerto. Conclusão: A cirurgia de Latarjet é um procedimento seguro e eficaz no tratamento da luxação anterior recidivante do ombro, possibilitando melhora funcional significativa de acordo com a escala de Rowe, com baixo número de recidivas. Nível de Evidência IV, Série de Casos.

Postoperative Functional Evaluation in Patients Undergoing Surgical Treatment of the Terrible Triad Injury of the Elbow / Avaliação funcional pós-operatória em pacientes submetidos a tratamento cirúrgico da tríade terrível do cotovelo

Abstract Objective To evaluate the functional results of patients submitted to a surgical approach for the treatment of the terrible triad of the elbow, analyzing the treatment methods used and associated epidemiological variables. Methods Patients who underwent surgical treatment for the terrible triad of the elbow from February 2018 to June 2020 at our service were evaluated. The identified sample consisted of 17 patients, but of these, only 13 completed all stages of the study and, therefore, were considered as the universe to be considered. Epidemiological information of interest was collected: age, sex, hand of dominance, affected side, characteristics and classification of injuries, trauma mechanism, time to surgery, type of procedure performed and range of motion. The Mason classification was used for radial head fractures and the Regan and Morrey classification for the coronoid process. In order to perform a functional analysis, the DASH and BRUCE questionnaires were applied. Results About 77% of the patients were male, 92% of the fracture mechanisms were due to high-energy trauma. Contrary to this, the predominance of the non-dominant side was observed as the most affected. Evaluating the results according to the time to start the treatment, the patients operated within 14 days had statistically better functional results. Conclusion Surgical treatment of TTIE generates acceptable functional results in most cases. The success of the treatment is related to the time interval between the trauma and the first surgery, in addition to the severity of the injuries.

Resumo Objetivo Avaliar os resultados funcionais dos pacientes submetidos a abordagem cirúrgica para o tratamento da tríade terrível do cotovelo, analisando os métodos de tratamento utilizados e variáveis epidemiológicas associadas. Métodos Foram avaliados pacientes submetidos aotratamento cirúrgico de tríade terrível do cotovelo de fevereiro de 2018 a junho de 2020 em nosso serviço. A amostra identificada foi de 17 pacientes, mas destes apenas 13 concluíram todas as etapas das pesquisas e por isso foram considerados como o universo a ser levado em consideração. Coletou-se informações epidemiológicas de interesse: idade, sexo, dominância, lado acometido, características e classificações das lesões, mecanismo do trauma, tempo para cirurgia, tipo de procedimento realizado e o arco de movimento. Foi utilizada a classificação de Mason para a fratura de cabeça do rádio e a de Regan e Morrey, para o processo coronoide. A fim de realizar uma análise funcional, aplicou-se os questionários de DASH e BRUCE. Resultados Cerca de 77% dos pacientes foram do sexo masculino, 92% dos mecanismos de fratura foram por trauma de alta energia. Contrariamente a esta, observou-se a predominância do lado não dominante como o mais afetado. Avaliando os resultados de acordo com o tempo para início do tratamento, os pacientes operados em até 14 dias obtiveram resultados funcionais estatisticamente melhores. Conclusão O tratamento cirúrgico da TTC gera resultados funcionais aceitáveis na maioria dos casos. O sucesso do tratamento está relacionado ao intervalo de tempo entre o trauma e a primeira cirurgia, além de se relacionar com a gravidade das lesões.

Evaluation of Screws Positioning in Latarjet Surgery: Is There a Correlation between Parallelism to Glenoid and Radiographic Complications? / Avaliação do posicionamento dos parafusos na cirurgia de Latarjet: Existe correlação entre paralelismo à glenoide e complicações radiográficas?

Abstract Objective To evaluate whether the parallelism of screws with glenoid in Latarjet surgery interferes in the positioning of the graft and to verify the reproducibility of a method of measuring screws positioning. Methods Retrospective, multicenter study, of patients with anterior shoulder instability submitted to modified Latarjet surgery and at least one year of postoperative follow-up. Two radiologists analyzed the postoperative tomographic images, acquired in a database, to evaluate the positioning of screws and radiographic complications. Results We evaluated 34 patients, aged between 21 and 60 years, one of them with bilateral shoulder involvement, totaling 35 shoulders evaluated. The tomographic evaluation of the inclination angles of the screws showed no difference between the observers. There was intra- and interobserver agreement to evaluate the following surgical parameters: graft position, presence or not of radiographic complications. Conclusion The technique described for measuring the parallelism of screws in Latarjet surgery presented a very good and excellent intra-observer agreement, respectively. Screw parallelism with glenoid is recommended; however, it is not a mandatory and unique condition to avoid radiographic complications.

Resultados Foram avaliados 34 pacientes, com idades entre 21 e 60 anos, sendo que um deles tinha acometimento bilateral dos ombros, totalizando 35 ombros avaliados. A avaliação tomográfica dos ângulos de inclinação dos parafusos não apresentou diferença entre os observadores. Houve concordância intra e interobservador para avaliação dos seguintes parâmetros cirúrgicos: posição do enxerto, presença ou não de complicações radiográficas. Conclusão A técnica descrita para mensuração do paralelismo dos parafusos na cirurgia de Latarjet apresentou uma concordância intra e inter observador muito boa e excelente, respectivamente. O paralelismo do parafuso com a glenoide é recomendado; no entanto, não é condição obrigatória e única para se evitar as complicações radiográficas.

Developmental Dysplasia of the Hip - Part 1 / Displasia do desenvolvimento do quadril - Parte 1

Abstract Developmental dysplasia of the hip (DDH) is a condition characterized by changes in joint formation within the last months of intrauterine life or the first months after birth. Developmental dysplasia of the hip presentation ranges from femoroacetabular instability to several stages of dysplasia up to complete dislocation. Early diagnosis is essential for successful treatment. Clinical screening, including appropriate maneuvers, is critical in newborns and subsequent examinations during the growth of the child. Infants with suspected DDH must undergo an ultrasound screening, especially those with a breech presentation at delivery or a family history of the condition. A hip ultrasound within the first months, followed by pelvic radiograph at 4 or 6 months, determines the diagnosis and helps follow-up. Treatment consists of concentric reduction and hip maintenance and stabilization with joint remodeling. The initial choices are flexion/abduction orthoses; older children may require a spica cast after closed reduction, with or without tenotomy. An open reduction also can be indicated. After 18 months, the choices include pelvic osteotomies with capsuloplasty and, eventually, acetabular and femoral osteotomies. The follow-up of treated children must continue throughout their growth due to the potential risk of late dysplasia.

Resumo O termo displasia do desenvolvimento quadril (DDQ) refere-se à condição na qual a articulação sofre alterações na sua formação durante os últimos meses da vida intrauterina ou nos primeiros meses após o nascimento. No espectro de apresentação, varia desde a instabilidade femuroacetabular, passando por estádios de displasia até a completa luxação. O diagnóstico precoce é fundamental para o sucesso do tratamento. A triagem através do exame clínico incluindo manobras apropriadas é imprescindível nos recém-nascidos e nas avaliações subsequentes durante o crescimento da criança. O rastreamento ultrassonográfico é indicado nos bebês sob suspeita clínica e muito mais recomendável naqueles que tiveram apresentação pélvica para o parto ou que tenham antecedentes familiares. A ultrassonografia do quadril nos primeiros meses seguida da radiografia da bacia após o 4° ou 6° mês de vida são os exames que determinam o diagnóstico e auxiliam o seguimento. O tratamento está baseado na obtenção de uma redução concêntrica e na manutenção e estabilização do quadril, propiciando a remodelação articular. Inicialmente, as órteses de flexão/abdução são a escolha; em crianças maiores pode ser necessário o uso de gesso após redução incruenta com ou sem tenotomia; redução aberta pode ser indicada e após os 18 meses as osteotomias pélvicas associadas a capsuloplastia e eventuais osteotomias acetabular e femoral. Crianças tratadas devem ser acompanhadas durante todo o seu crescimento pelo eventual risco de displasias tardias.

Evaluation of tenotomy in the hip subluxation treatment of children with zika syndrome / Avaliação da tenotomia no tratamento da subluxação do quadril de crianças com zika

ABSTRACT Objectives: Evaluate the efficacy and effects of releasing the muscles of subluxated hips of patients with SCZ. Methods: This is a retrospective study with 29 patients with subluxation of the hip, corresponding to 55 hips operated in a public hospital in Recife, Brazil. Preoperative femoral head migration (PM) percentages were evaluated and compared with 6- and 12-month postoperative results. Results: Twenty-nine patients were eligible, representing 55 hips evaluated. 19 were female (65.5%), with a mean age of 31.45 months (ranging from 23 to 42 years). 19 patients were GMFCS level V (65.5%), 34.5% were level IV, and 20 of the 29 patients (69%) had no complications. The PM had an absolute reduction of 11.6% (GMFCS IV) and 13.31% (GMFCS V) in the first six months. After 12 months, there was a regression of MP of 7.14% (GMFCS V) and 11.25% (GMFCS IV) compared to preoperative values, with no significant statistical difference among MP values presented between 6 and 12 months after surgery. Conclusions: The surgery was effective in PM regression during the analyzed period and presented a low complication rate. Level of Evidence III; Comparative retrospective study.

Analysis of 45,507 surgical treatment of distal tibia and malleolar fractures over 14 years / Análise de 45.507 tratamentos cirúrgicos das fraturas distais da tíbia e do tornozelo ao longo de 14 anos

ABSTRACT The distal leg joint fractures are among the most common fractures in humans across all age groups, and 50% of them require surgical treatment. Few studies discuss the epidemiology and costs of this fracture in the global and national literature. Objective: To evaluate the annual incidence and reimbursement value of distal leg joint fractures requiring surgical treatment from 2008 to 2021. Methods: A retrospective study was conducted to analyze the complex structured data of high volume and high variability (Big Data), publicly available on the TabNet platform (DATASUS), via software with artificial intelligence. Data from 2008 to 2021 on surgical treatment for malleolar fracture, distal tibia fracture, and isolated fibula fracture were analyzed. Results: From 2008 to 2021, there was an average incidence of 28.8 fractures/105 inhabitants per year, representing 14.62% of all fractures. The total amount paid for hospitalizations due to these fractures was R$ 34,218,014.62 over these 14 years. Conclusion: The incidence of distal leg joint fractures follows the pattern of those recorded in other countries. The adjustment of reimbursement over the years was lower than the accumulated inflation. Level of Evidence II, Economic and Decision Analyses - Developing an Economic or Decision Model.

Early detection and risk factors of congenital hip dislocation in Morocco

Background and Objective: Congenital dislocation of the hip is a malformation of the lower limbs that could be complicated by a disabling physical handicap with long-term psychological and social repercussions if detected late. This study aims to describe the screening for congenital hip dislocation and to investigate the association between the occurrence of this anomaly and possible risk factors in Morocco. Methods: The study was based on the exploitation of the records of children treated at the trauma and orthopedics department of the Mohammed VI University Hospital in Marrakech, Morocco. It concerned 160 cases with a 5-year follow-up from January 2016 to March 2021. Results: The results of the study showed that 56.7% of the affected children had a bilateral dislocation and 25.8% of the cases had a left-sided dislocation. The malformation occurred more frequently in females 69.2%. A familial disposition to the malformation was found in about 22% of the cases. The diagnosis was late (at walking age) in 61% of children following the onset of lameness with or without pain in 91% of children. In 41.87% of the hips, the reduction was surgical, with 28% failure dominated by acetabular dysplasia in 11%. Conclusion: The risk factors for congenital hip dislocation identified in our setting were dominated by sex, primiparity, consanguineous marriage, and the presence of a family history of dislocation. Communication of risk factors specific to our setting to healthcare personnel will allow them to guide the diagnosis and increase vigilance in the at-risk population for management that prevents the development of complications.

Finite element analysis of different reconstruction methods of coracoclavicular ligament for acromioclavicular joint dislocation / 中国骨伤

OBJECTIVE@#This study aims to examine the biomechanical effects of different reconstruction methods, including single-bundle, double-bundle anatomical reconstruction, and double-bundle truly anatomical reconstruction of the coracoclavicular ligament on the acromioclavicular joint using finite element analysis, to provide a theoretical basis for the clinical application of truly anatomical coracoclavicular ligament reconstruction.@*METHODS@#One volunteer, aged 27 years old, with a height of 178 cm and a weight of 75 kg, was selected for CT scanning of the shoulder joint. Three-dimensional finite element models of single-bundle reconstruction, double-bundle anatomical reconstruction, and double-bundle truly anatomical reconstruction of coracoclavicular ligament were established by using Mimics17.0, Geomagic studio 2012, UG NX 10.0, HyperMesh 14.0 and ABAQUS 6.14 software. The maximum displacement of the middle point of the distal clavicle in the main loading direction and the maximum equivalent stress of the reconstruction device under different loading conditions were recorded and compared.@*RESULTS@#The maximum forward displacement and the maximum backward displacement of the middle point of the distal clavicle in the double-bundle truly anatomic reconstruction were the lowest, which were 7.76 mm and 7.27 mm respectively. When an upward load was applied, the maximum displacement of the distal clavicle midpoint in the double-beam anatomic reconstruction was the lowest, which was 5.12 mm. Applying three different loads forward, backward, and upward, the maximum equivalent stress of the reconstruction devices in the double-beam reconstruction was lower than that in the single-beam reconstruction. The maximum equivalent stress of the trapezoid ligament reconstruction device in the double-bundle truly anatomical reconstruction was lower than that in the double-bundle anatomical reconstruction, which was 73.29 MPa, but the maximum equivalent stress of the conoid ligament reconstruction device was higher than that of the double-bundle anatomical reconstruction.@*CONCLUSION@#The truly anatomical reconstruction of coracoclavicular ligament can improve the horizontal stability of acromioclavicular joint and reduce the stress of the trapezoid ligament reconstruction device. It can be a good method for the treatment of acromioclavicular joint dislocation.
