Traumatic atlanto-occipital dislocation with improvement of neurological deficit: case report / Luxação traumática atlanto-occipital com melhora do déficit neurológico: relato de caso / Luxación atlanto-occipital traumática con mejoría del déficit neurológico: informe de un caso

ABSTRACT: Traumatic atlanto-occipital dislocation is a rare, severe, and usually fatal injury. In this paper, we report the case of a 28-year-old patient with multiple trauma, who suffered an atlanto-occipital dislocation (AOD) associated with rotatory dislocation at C1-C2, condyle fracture and traumatic brain injury resulting from a car accident, with a cardiopulmonary arrest at the accident site. The patient had motor and sensory deficits, suffering other complications of clinical severity during hospitalization. After two years of surgical treatment follow-up, the patient had a complete recovery of neuromotor and sensory functions. This case demonstrates that neurological recovery with minimal sequelae is possible, even after an unfavorable prognosis resulting from a severe injury with a high risk of death as this kind of trauma. It is essential for health professionals to have the ability to identify and treat AOD, ensuring improved clinical outcomes, reducing mortality and morbidity, and providing a better life to affected patients.

Comparison between portals for placement of anchors in shoulder instability / Comparação entre portais para colocação de âncoras na instabilidade do ombro

ABSTRACT Objective: to radiographically compare the effects of anchor positioning in the arthroscopic treatment of shoulder instability, in the 3- and 5-o'clock portals. Methods: retrospective study of 36 patients, operated by two shoulder surgeons at the Unimed BH hospital, between January 2013 and January 2018. Each surgeon used only one of either the 3- or the 5-o'clock portal. After postoperative radiographs we performed angle comparisons between the greatest glenoidal axis, the angle of anchor insertion and distance from the inferior pole. Results: the 5-o'clock portal provided better placement than its 3-o'clock counterpart, which allowed for greater orthogonality in relation to the glenoid rim (p < 0.05). Conclusion: the 5-o'clock portal allowed for better anchor placement than the 3 o'clock one. Level of Evidence II, Clinical Trial.

RESUMO Objetivo: Comparar radiograficamente o posicionamento das âncoras utilizadas no tratamento artroscópico da instabilidade do ombro, através dos portais de 3 ou 5 horas. Métodos: Avaliação retrospectivae de 36 pacientes, operados por dois cirurgiões de ombro do Hospital Unimed BH, entre janeiro de 2013 e janeiro de 2018. Cada cirurgião utilizou apenas uma das técnicas - portal de 3 ou 5 horas. As radiografias pós-operatórias foram avaliadas e comparadas a angulações entre o maior eixo da glenoide, o ângulo de inserção da âncora e a distância em relação ao polo inferior. Resultados: A utilização do portal de 5 horas propiciou a colocação mais adequada das âncoras em relação ao portal de 3 horas, permitindo o posicionamento mais ortogonal em relação à borda da glenoide (p < 0,05). Conclusão: A utilização do portal de 5 horas apresenta melhor posicionamento das âncoras quando comparado ao portal de 3 horas. Nível de evidência II, Ensaio Clínico.

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

Material y métodos: un hombre de 31 años, sin antecedentes médicos de interés, sufrió un accidente de tráfico de alta energía. Presentaba una luxación del tendón tibial posterior que pasó desapercibida. Tras un diagnóstico precoz se consiguió realizar una reparación primaria del retináculo flexor y se logró la reducción anatómica del tendón. Resultados: el paciente pudo retomar la actividad deportiva a los tres meses de la lesión con buen resultado funcional. Conclusiones: debemos sospechar esta entidad tras un traumatismo de alta energía con entorsis de tobillo. El tratamiento quirúrgico de esta lesión ofrece buenos resultados funcionales.

Abstract: Introduction: traumatic posterior tibial tendon dislocation is a rare entity that can go unnoticed in our usual clinical practice. Material and methods: a 31-year-old man, with no relevant medical history, suffered a high-energy traffic accident. He presented a dislocation of the posterior tibial tendon that went unnoticed. After an early diagnosis, a primary repair of the flexor retinaculum was performed and the anatomical reduction of the tendon was achieved. Results: the patient was able to resume sports activity three months after the injury with good functional results. Conclusions: we should suspect this entity after high-energy trauma with ankle sprains. Surgical treatment of this lesion offers good functional results.

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.

Luxación bilateral central femoral tras crisis convulsiva. Anillo antiprotrusivo y cotilo de doble movilidad como opción terapéutica. A propósito de un caso / Bilateral central femoral dislocation after seizure. Antiprotrusive ring and dual mobility cup as a therapeutic option. Apropos of a case

Resumen: Introducción: las crisis convulsivas pueden desencadenar fracturas y luxaciones. Las lesiones dependen de la severidad, duración y el tipo de crisis. Presentamos un caso clínico de un varón que presentó una fractura luxación central bilateral de cadera tras episodio de crisis convulsiva. Un caso pocas veces descrito en la literatura con un manejo complejo y poco habitual. Caso clínico: paciente de 77 años con antecedentes de deterioro cognitivo moderado que sufrió una luxación bilateral central de cadera en contexto de una crisis convulsiva generalizada. Clínicamente, a su llegada a urgencias, el paciente presentaba un acortamiento de la extremidad inferior derecha en comparación con la contralateral, rotación externa y bloqueo articular a la realización del log roll test en ambas extremidades. Se realizó estudio de imagen y optimización clínica previo a cirugía. Se realizó en dos tiempos: primero la cadera izquierda al octavo día de ingreso y la cadera derecha al decimoquinto. En ambas cirugías se realizó el mismo procedimiento mediante implantación de anillo antiprotrusivo y prótesis con cotilo de doble movilidad con vástago femoral no cementado. En el postoperatorio inmediato, el paciente no presentó ninguna complicación asociada a la cirugía. En el seguimiento a los 12 meses, el paciente realiza carga completa con un Harris hip score (HHS) de 77 cadera derecha y 79 en la izquierda; 12 puntos en la escala WOMAC. No ha presentado complicaciones postoperatorias hasta el momento. Conclusiones: estas lesiones son poco comunes en nuestra práctica diaria, donde disponemos de múltiples opciones para abordarlas. En nuestro paciente, el empleo de la artroplastía y de anillos antiprotrusivos nos ofrecen ventajas respecto a las técnicas de síntesis de la fractura, como una movilización precoz y evitar desarrollo prematuro de una artrosis postraumática, con resultados buenos, funcionales y pocas complicaciones postoperatorias.

Abstract: Introduction: seizures can trigger fractures and dislocations. Injuries depend on the severity, duration and type of seizure. We present a case report of a male patient who presented with a bilateral central dislocation fracture of the hip following an episode of seizure. A case rarely described in the literature with complex and unusual management. Case report: a 77-year-old man with a history of moderate cognitive impairment suffered a bilateral central dislocation of the hip in the context of a generalized epileptic seizure. Clinically on arrival at the emergency department, the patient presented shortening of the right lower extremity compared to the contralateral, external rotation and joint locking on log roll test in both extremities. An imaging study and clinical optimization were performed prior to surgery. It was performed in two stages. First the left hip on the 8th day of admission, and the right hip on the 15th. In both surgeries the same procedure was performed, with implantation of an antiprotrusive ring and a double mobility cup prosthesis with an uncemented femoral stem. In the immediate postoperative period, the patient did not present any complications associated with the surgery. At 24-month follow-up, the patient performed full weight bearing with a Harris hip score (HHS) of 77 on the right hip and 79 on the left; 12 points on the WOMAC scale. No postoperative complications have occurred so far. Conclusions: these injuries are uncommon in our daily practice, where multiple options are available to address them. In our patient, the use of arthroplasty and antiprotrusive rings offers advantages over fracture synthesis techniques, such as early mobilization with moderate functional results and few postoperative complications.

Objective: To determine the presence of dysplasia and hip dislocation in children with congenital disorders who attend a national rehabilitation institute. Material and Methods: An observational, descriptive, retrospective and cross-sectional study was conducted using 150 medical records of children from 0 to 2 years of age with congenital disorders with musculoskeletal involvement. Results: The patients had a median age of 11 months and 64% were female. The most frequent alteration was congenital deformity of the hip (52%), followed by spina bifida, congenital deformity of the ECOM, multiple arthrogryposis, and congenital deformity of the feet (23.3%, 6.7%, 5.3% and 4%, respectively). In addition, 17.3% of patients with congenital abnormalities had dislocation, 56.7% had dysplasia and 72.7% had either of the two. In patients with congenital hip deformity, 100% had dysplasia and/or dislocation. In patients with spina bifida, 54.3% had at least one of them. Moreover, 75% of patients with arthrogryposis multiplex and 33.3% of those with congenital deformities of the feet presented dysplasia and/or dislocation. Conclusions: Dysplasia and/or dislocation of the hip are common in children with a diagnosis of congenital hip deformity, spina bifida, congenital arthrogryposis multiplex, and congenital foot deformities.

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.

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.

Surgical methods and treatment effects of the adult anterior dislocation of the sacroiliac joint / 中华骨科杂志

Objective:To explore the surgical methods and treatment effects of adult anterior dislocation of the sacroiliac joint (AADSJ).Methods:A multi-center retrospective case series study was conducted to analyze the clinical data of 25 cases admitted in 5 clinical centers (affiliations of authors in this article) from January 2016 to January 2021. There were 18 males and 7 females, aged 38.8±15.5 years (range, 18-83 years). The AADSJ clinical classification system was formulated based on the radiographic morphology of anterior dislocation of the sacroiliac joint, which includes two types. Type I: complete anterior dislocation of the sacroiliac joint, and displacement of the entire iliac auricular surface to the front of the sacrum. Type II: fracture of the sacroiliac joint combined with anterior dislocation, subdivided into 3 subtypes. Type IIa: iliac fracture involves the anterior 1/3 of the sacroiliac joint, and dislocation of the ilium anterior to the sacrum. Type IIb: iliac fracture involves the posterior 2/3 of the sacroiliac joint, and dislocation of the ilium anterior to the sacrum. Type IIc: iliac fracture involves the posterior 2/3 of the sacroiliac joint, and dislocation of the ilium anteromedial to the sacrum. The reliability and repeatability of the clinical classification, Tile classification and Young-Burgess classification were performed based on the results of two-phase assessments in four observers. The operations were performed by the lateral-rectus approach and the ilioinguinal approach. The operation time and intraoperative bleeding were recorded. Pelvic X-ray and CT scan were rechecked after the operation. The quality of fracture reduction was evaluated according to Matta score. The postoperative functional rehabilitation was evaluated according to the Majeed rehabilitation standard at one-year follow-up.Results:Among 25 cases in this study, there were 3 cases of Type I, 5 cases of Type IIa, 9 cases of Type IIb and 8 cases of Type IIc according to the clinical classification system. The Kappa values of reliability tests for the clinical classification, Tile classification and Young-Burgess classification were 0.681, 0.328 and 0.383, respectively. The Kappa values of repeatability tests for the clinical classification, Tile classification and Young-Burgess classification were 0.690, 0.221 and 0.395, respectively. The reliability and repeatability of the AADSJ clinical classification were significantly better than other classifications. There were 14 cases underwent lateral rectus abdominis approach and 11 cases underwent ilioinguinal approach. The operative time for managing anterior dislocation of the sacroiliac joint was 122.0±50.7 min (range, 65-148 min) through the lateral rectus abdominis approach, and through the ilioinguinal approach was 178.0±49.9 min (range, 110-270 min), with a significant difference ( t=2.76, P=0.011). The amount of intraoperative blood loss through the lateral rectus approach was 680±330 ml (range, 350-2,120 ml), which was significantly less than that through the ilioinguinal approach (1,660±968 ml, 680-3,300 ml), with a significant difference ( t=3.55, P=0.002). The follow-up period was 1-3 years. At one week after surgery, the quality of fracture reduction evaluated by Matta score showed that the excellent and good reduction rate of the lateral-rectus approach was 79% (11/14), and that of the ilioinguinal approach was 73% (11/14), with no statistically significant difference ( P=1.000). At a one-year follow-up, according to Majeed's criteria, the overall excellent and good rate of the lateral-rectus approach was 64% (9/14), which is similar to 64% (7/11) of that of the ilioinguinal approach. No fracture reduction loss or internal fixation loosening failure occurred. Conclusion:The AADSJ clinical classification system can accurately describe the imaging features and clinical manifestations of AADSJ, with high reliability and repeatability. The AADSJ can be treated by the lateral-rectus approach or the ilioinguinal approach, with similar therapeutic effects but the former having less trauma.

Posterior reduction for treatment of acute severe traumatic lumbar spondylolisthesis / 中华创伤骨科杂志

Objective:To evaluate the clinical effects of posterior reduction in the treatment of acute severe traumatic lumbar spondylolisthesis.Methods:A retrospective study was conducted to analyze the clinical data of 12 patients with acute severe traumatic lumbar spondylolisthesis who had been treated by posterior reduction at Department of Spinal Surgery, Zhengzhou Orthopaedic Hospital from June 2010 to December 2018. There were 7 males and 5 females with an age of (25.7±1.8) years. The spondylolisthesis was at L4 in 4 cases and at L5 in 8 cases, and grade Ⅲ in 7 cases, grade Ⅳ in 4 cases and grade Ⅴ in 1 case according to the Meyerding classification. By the American Spinal Injury Association (ASIA) grading, the preoperative neurological function was at level B in 6 cases, at level C in 4 cases, and at level D in 2 cases. All the 12 patients underwent posterior reduction and internal fixation with pedicle screws, as well as intervertebral bone graft fusion. Operation time and intraoperative blood loss were recorded. Clinical efficacy was evaluated by visual analogue scale (VAS) and Oswestry disability index (ODI) before and after surgery, and neurological function was evaluated by ASIA grading. X-ray, CT plain scan and reconstruction were used to observe internal fixation and bone grafting.Results:All patients were followed up for (18.5±2.1) months. The operation time was (165.7±42.3) min and the blood loss (497.7±75.3) mL. The VAS pain scores [(2.7±0.3) points and (1.8±0.2) points] and ODIs (18.2%±2.3% and 14.5%±2.6%) at 2 weeks after operation and at the last follow-up were significantly lower than the preoperational values [(8.5±0.6) points and 72.3%±12.3%] ( P<0.05), but there was no statistically significant difference between 2 weeks after operation and the last follow-up ( P>0.05). At the last follow-up, X-rays and CT scans showed good fixation and adequate bone grafting; the spondylolisthesis was grade 0 in 10 cases and grade I in 2 cases; the ASIA level of neurological function was C in 2 cases, D in 3 cases, and E in 7 cases. Healing of surgical incision was delayed in 2 patients but responded to symptomatic treatment. Follow-ups observed no such complications as loosening or pulling out of internal fixation. Conclusion:In the treatment of acute severe traumatic lumbar spondylolisthesis, posterior reduction can effectively restore the spondylolisthesis sequence and restore spinal stability, leading to satisfactory curative outcomes.

Diagnosis and treatment of posterior shoulder dislocation combined with reverse Hill-Sachs lesion / 中华创伤骨科杂志

Objective:To explore the diagnosis and treatment of posterior shoulder dislocation combined with reverse Hill-Sachs lesion.Methods:Two male patients were treated at Department of Joint Surgery, Affiliated Hospital of Qingdao University for posterior shoulder dislocation combined with reverse Hill-Sachs lesion from August to November 2022. Case 1 was a 46-year-old man, admitted 1 day after right should injury, and case 2 a 57-year-old man, admitted 2 days after right should injury. The injury was caused by electric shock in both, and their fractures were fresh with an injury area>50%. After anatomical reduction of the collapsed humeral head via the pectoralis major deltoid approach, an artificial bone was implanted and fixated with countersunk screws in both cases to reduce the shoulder joint. The Constant-Murley scale and visual analogue scale (VAS) were used to evaluate the functional recovery of the shoulder and pain after treatment.Results:No such perioperative complications as incision infection, brachial plexus injury or vascular injury was observed in either of the 2 patients. Reexamination 3 months after surgery showed in case 1: 110° of shoulder anterior flexion, 90° of shoulder abduction, 30° of external rotation (neutral position), 70° of internal rotation (neutral position), 70 points of Constant-Murley shoulder score, and 3 points of VAS pain score; in case 2: 130° of shoulder anterior flexion, 120° of shoulder abduction, 50° of external rotation (neutral position), 80° of internal rotation (neutral position), 70 points of Constant-Murley shoulder score, and 2 points of VAS pain score.Conclusion:For patients with posterior shoulder dislocation complicated with reverse Hill-Sachs lesion and humeral head collapse greater than 50%, open reduction and screw internal fixation combined with artificial bone grafting can achieve good short-term curative efficacy.
