Visual trephine arthroplasty assisted percutaneous transforaminal endoscopic discectomy for lumbar disc herniation / 中国骨伤

OBJECTIVE@#To compare the clinical efficacy between visual trephine arthroplasty assisted percutaneous transforaminal endoscopic discectomy (VPTED) and traditional percutaneous transforaminal endoscopic discectomy(PTED) in the treatment of lumbar disc herniation.@*METHODS@#The clinical data of 60 patients with lumbar disc herniation admitted from June 2019 to December, 2020 was retrospectively analyzed. There were 38 males and 22 females, aged from 26 to 58 years old with an average of (43.63±8.48) years, 47 cases were on L4,5 segment and 13 cases were on L5S1 segment. Among them, 32 were treated with VPTED (group A) and 28 were treated with traditional PTED (group B). The general conditions of all the patients were recorded, including intraoperative fluoroscopy times, operation time, hospital stay and surgical complications during follow-up. The arthroplasty area ratio was observed by sagittal CT at the middle level of the intervertebral foramen. Visual analogue scale (VAS) and Japanese Orthopaedic Association (JOA) score of low back pain, Oswestry disability index (ODI) were used to evaluate the clinical efficacy between two groups.@*RESULTS@#All patients were followed up from 9 to 15 months with an average of (12.10±1.16) months. There was no statistical difference of preoperative general data between two groups. The operation time, fluoroscopy times and hospital stay were (70.47±5.87) min, (13.66±1.34) times and (6.31±0.69) d in group A, and (90.71±7.66) min, (22.82±2.48) times and (6.54±0.92) d in group B. The operation time and intraoperative fluoroscopy times in group A were lower than those in group B(P<0.05). There was no significant difference in hospital stay between two groups (P>0.05). No obvious surgical complications were found during the follow-up in both groups. The arthroplasty area ratio in group A was (29.72±2.84)% and (29.57±2.20)% in group B, respectively, with no significant difference (P>0.05). There was no significant difference in VAS, ODI and JOA score between two groups before operation and at the final follow-up(P>0.05), but the final follow-up was significantly improved(P<0.05).@*CONCLUSION@#The two surgical methods have definite clinical efficacy in the treatment of lumbar disc herniation. Visual trephine arthroplasty assisted percutaneous transforaminal endoscopic discectomy has the advantages of high efficiency and rapidity when establishing the channel, and can significantly reduce the operation time and intraoperative fluoroscopy times.

Quality of life analysis on patients after arthroplasty or lumbar arthrodesis / Análise da qualidade de vida em pacientes pós artroplastia ou artrodese lombar / Análisis de la calidad de vida en pacientes tras una artroplastia o artrodesis lumbar

ABSTRACT Objective: To perform a retrospective analysis of patients with degenerative disc disease of the lumbar spine undergoing arthrodesis or lumbar arthroplasty in terms of functional capacity and quality of life. Methods: Retrospective observational study analyzing the medical records of patients undergoing arthrodesis or lumbar arthroplasty, followed-up at an outpatient clinic from 2018 to 2020. Patient characteristics were evaluated; the quality of life through the results of the Short Form 36 Health Survey Questionnaire (SF-36) and the functional capacity using the Oswestry Disability Index (ODI) in the pre-surgical and post-surgical periods (6 months, 1 and 2 years). The criterion to establish statistical significance was p≤0.05. Results: Sixty-one patients were evaluated. After the surgical interventions, the individuals migrated from the classification of invalid (61.4%-64.6%) to minimal/moderate disability (17.7%-25.6%). There was a decline in ODI scores over time of follow-up (p≤0.001) as well as in SF-36 values (p≤0.001) for all surgical techniques. In this regard, evaluating the difference in means revealed the better performance of lumbar arthroplasty (p≤0.001). Conclusion: The data suggest that lumbar arthroplasty offers greater benefits to patients regarding functional capacity and quality of life. Level of Evidence III; Retrospective, descriptive, observational study.

Quanto ao tempo de espera pela ATJ, 56,67% dos pacientes esperaram até 90 dias; 16,67% entre 90 e 180 dias e 26,67% esperaram mais de 180 dias. Foi demonstrada melhora significativa entre as condições clínicas pré e pós ATJ, como mobilidade, edema, rigidez matinal e dor. A redução da dor foi preditora significativamente mais associada com a satisfação com o procedimento. Análise de regressão verificou que os piores resultados foram encontrados nos pacientes que esperaram por mais de 90 dias pela ATJ. Conclusão: o tempo de espera causa um impacto significativo no cotidiano dos pacientes submetidos à ATJ. Quanto maior o tempo de espera, piores são os resultados funcionais, a satisfação e a qualidade de vida desses pacientes.

Objective: to evaluate the relationship between quality of life and waiting time for total knee arthroplasty (TKA) in patients using the public health system. Method: an observational, retrospective, cross-sectional study from January to June 2021. Patients aged 50 years or older who joined the waiting list for surgical treatment for total knee arthroplasty in September 2018 in a tertiary public hospital were included in the study. Data were collected using a questionnaire developed and validated by the institution's own psychology service and processed using descriptive and inferential statistics. Results: thirty patients participated in the research, aged 67 ± 6.63 years, 70% female, and with a mean monthly income of R$1,558.00. Regarding the waiting time for TKA, 56.67% of patients waited up to 90 days; 16.67% between 90 and 180 days, and 26.67% waited more than 180 days. Significant improvement was demonstrated between pre-and post-TKA clinical conditions, such as mobility, edema, morning stiffness, and pain. Pain reduction was significantly more predictor associated with satisfaction with the procedure. Regression analysis found that the worst outcomes were found in patients who waited longer than 90 days for TKA. Conclusion: waiting time has a significant impact on the daily lives of patients undergoing TKR. The longer the waiting time, the worse are the functional results, satisfaction, and quality of life of these patients.

Anthropometric Tomographic Study of the Hip in a Brazilian Regional Population / Estudo antropométrico tomográfico do quadril em uma população regional brasileira

Abstract Objective The present study aimed to determine the average hip anthropometry of a regional Brazilian population using measurements based on computerized axial tomography (CAT). Methods Retrospective, descriptive analysis of hip measurements from 200 abdominal CATs from patients visiting a medical center. The tests were selected at random to determine 30 previously defined anthropometric measurements. The data were statistically analyzed and compared according to gender and age. Results The prevalence of hip dysplasia was 6%. Signs suggesting femoroacetabular impingement were seen in 26% of cases. Patients over 50 years old presented significantly greater measures of horizontal acetabulum sectors, center-edge angle, and acetabular arch, as well as lower extrusion index, cervical-diaphyseal angle and vertical offset. Some measurements were significantly different according to gender: the lateral center-edge angle (µ » 35.5°) and the acetabular arch (µ » 68.7°) were higher in females. Males presented increased extrusion index (µ » 16%), lateral offset (µ » 38.3 mm), depth (µ » 19.5 mm), and neck diameter (µ » 26.4 mm). Conclusion The present study characterized the hip anthropometry of a regional Brazilian population. It also demonstrated significant morphological differences per age group and gender.

A case series measuring functional outcomes in adult patients who underwent hip arthroplasty using the modified trochanteric slide approach

Background@#Different trochanteric osteotomies have been developed to aid in surgical exposure and proper removal and placement of arthroplasty components. Objectives. The study aimed to measure functional outcomes of the modified trochanteric slide approach for both primary and revision hip arthroplasty with radiologic and clinical variables, identify preoperative indications for the approach and identify possible postoperative complications. @*Methods@#We conducted a retrospective case series of patients who underwent the modified trochanteric slide approach for hip arthroplasty at the orthopedic department of a tertiary hospital from 2012 to 2016. We reviewed patient charts and radiographs. Descriptive statistics were used to analyze data. @*Results@#Out of nine patients screened, seven were included. The average post-op hip range of motion was 42 degrees abduction and 98 degrees flexion. The union rate was 36% and the non-union rate was 7%. @*Conclusion@#The modified osteotomy is still recommended for difficult primaries and revisions to aid in exposure and hip biomechanics post-operatively.

Caracterización de pacientes con fractura de cadera, intervenidos con artroplastia / Characterizing Patients with Hip Fracture, Operated with Arthroplasty

Introducción: Las lesiones traumáticas de la cadera ocupan uno de los propósitos más importantes de la cirugía traumatológica. El uso de la artroplastia como regla de oro en el tratamiento quirúrgico de las mismas, es el fundamento del trabajo. Objetivo: Caracterizar los pacientes con diagnóstico de fractura de cadera, intervenidos con artroplastia total y parcial y estudiar la mortalidad, según el tipo de prótesis utilizada. Métodos: Se realizó un estudio descriptivo de corte transversal retrospectivo en 1506 pacientes del Hospital Ortopédico Docente Fructuoso Rodríguez entre 2015 y 2019, portadores de fractura de cadera, y tratados con artroplastia. Se analizaron variables tales como edad, sexo y comorbilidades presentes. Resultados: Se colocaron prótesis totales a 427 pacientes y en 1079 se utilizó la modalidad de prótesis parcial. Predominaron las personas entre 61 y 80 años de edad. El sexo femenino prevaleció en el estudio, con una relación 3:1. Predominó el grupo de pacientes con 1 o 2 enfermedades asociadas. La mortalidad < 30 días resultó el 1,1 por ciento y ≥ 30 días el 9,2 por ciento. Conclusiones: La utilización de prótesis totales dista mucho de la media interpuesta actualmente en el mundo, donde la prótesis total se maneja como herramienta de elección. Las prótesis parciales quedan reservadas para pacientes que tienen una corta expectativa de vida y muy poco validismo(AU)

Introduction: Traumatic hip injuries occupy one of the most important purposes of trauma surgery. The use of arthroplasty as a golden rule in their surgical treatment is the foundation of the work. Objectives: To characterize patients with a diagnosis of hip fracture, who underwent total and partial arthroplasty and to study mortality, according to the type of prosthesis used. Methods: A descriptive retrospective cross-sectional study was carried out in 1506 patients from Fructuoso Rodríguez Orthopedic Teaching Hospital from 2015 to 2019, with hip fracture, and treated with arthroplasty. Variables such as age, sex, and present comorbidities were analyzed. Results: Total prostheses were placed in 427 patients and in 1079 the partial prosthesis modality was used. Persons between 61 and 80 years of age predominated. The female sex prevailed in this study, with a 3: 1 ratio. The group of patients with 1 or 2 associated diseases predominated. Mortality <30 days was 1.1 percent and ≥30 days was 9.2 percent. Conclusions: The use of total prostheses is far from the current average in the world, where the total prosthesis is used as the tool of choice. Partial prostheses are reserved for patients who have short life expectancy and very little validity(AU)

Poisoning by metals used in prothetic materials in orthopedics and its current management / Envenenamiento por metales en materiales protésicos en ortopedia y su tratamiento actual

Fracturas por epilepsia en el hospital Víctor Lazarte Echegaray / Epilepsy Fractures at Víctor Lazarte Echegaray Hospital

Introducción: Las convulsiones pueden producir una tensión muscular significativa capaz de fracturar el hueso. Se halló que el aumento significativo en la incidencia de fracturas se encuentra dentro del grupo de edad entre 45 a 64 años, lo que demuestra que los epilépticos no solo son más vulnerables a las fracturas, sino que tienen un comienzo de fractura más precoz. Las medidas de prevención comprenden suplementos de calcio, vitamina D, densitometría ósea y tratamiento con bifosfonatos, que deben reforzarse en pacientes con epilepsia que tienen riesgo de osteoporosis. Objetivo: Presentar casos de fracturas extracapsular e intracapsular de la cadera por convulsiones epilépticas, atendidos en el hospital Víctor Lazarte Echegaray, Trujillo, Perú, en el periodo comprendido entre 2013 y 2019. Presentación de los casos: Se reporta dos casos de fractura de cadera por convulsiones epilépticas, uno con fractura del acetábulo e iliaco izquierdo y otro a nivel del cuello femoral y subtrocantérica. Conclusiones: Las personas con convulsiones epilépticas poseen un mayor peligro de fracturas, por consiguiente se recomienda a los médicos que maximicen su conciencia sobre las fracturas relacionadas a convulsiones, en especial a pacientes con dolor postictal, debido a que los síntomas pueden ser inespecíficos y una mala interpretación puede impedir la rehabilitación(AU)

Introduction: Seizures can produce significant muscle tension capable of fracturing the bone. The significant increase in the incidence of fractures was found to be within the age group between 45 and 64 years, which shows that epileptics are not only more vulnerable to fractures, but also have earlier fracture onset. Prevention measures include calcium supplements, vitamin D, bone densitometry, and bisphosphonate treatment that should be reinforced in patients with epilepsy who are at risk for osteoporosis. Objective: To present cases of hip fractures due to epileptic seizures, treated at Víctor Lazarte Echegaray Hospital, Trujillo, Peru, from 2013 to 2019. Case report: Cases of hip fracture due to epileptic seizures have been reported, one with fracture of the acetabulum and left iliac and another at the level of the femoral and subtrochanteric neck. Conclusions: Individuals with epileptic seizures have greater risk of fractures, it is recommended that physicians maximize their awareness of seizure-related fractures, especially in patients with postictal pain, since the symptoms can be nonspecific and misinterpretation can prevent rehabilitation(AU)

Arthroscopic Bankart repair combined with Reimplissage for the treatment of recurrent anterior dislocation of shoulder in adults with Hill-Sachs defect / 中国骨伤

OBJECTIVE@#To investigate the method and clinical effects of the treatment of recurrent anterior dislocation of shoulder with Hill-Sachs injury by arthroscopic Bankart repair and Remplissage.@*METHODS@#From March 2016 to March 2019, 106 patients with recurrent anterior dislocation of shoulder with glenoid bone defect less than 20% underwent arthroscopic Bankart repair, including 76 males and 30 females, aged from 18 to 45 (27.3±8.6) years, 59 cases of left shoulder and 47 cases of right shoulder. Range of motion (ROM), American Shoulder and Elbow Surgeons(ASES) score, Constant-Murley score and Rowe score were used to evaluate shoulder functionand stability before and after operation.@*RESULTS@#All patients were followed up, and the duration ranged from 21 to 60 months, with a mean of (41.5± 8.5) months. One patient developed infection after operation, and the infection was controlled after arthroscopic debridement again. The remaining patients did not have clinical complications such as infection, intra articular hematocele and redislocation. Shoulder flexion and lifting increased from (158.33±15.72) ° preoperatively to (169.43±10.04) ° at the latest follow up, and internal rotation changed from T7 (T4 to T10) preoperatively to T8 (T5 to T10) at the latest follow up;the average lateral external rotation and abduction 90 ° external rotation decreased from (58.46±15.51) ° preoperatively and (99.37±14.09) ° to (53.18±14.90) ° and (92.52±13.10) ° at the latest follow up, respectively. The ASES score, Constant -Murley score and Rowe score were significantly improved.@*CONCLUSION@#The clinical effect of rehabilitation of Bankart repair combined with Remplissageunder arthroscopy in the treatment of recurrent dislocation of shoulder joint in adults with Hill-Sachs defect is satisfactory. Although the external rotation function is weaker than that before operation, it can effectively reconstruct the shoulder function and avoid the occurrence ofdislocation after operation.

Comportamiento de reingreso a 30 días en un centro de reemplazos articulares. Estudio de cohorte longitudinal / 30 days re-admission in an articular Joint Arthroplasty center. A cohort Study

Introducción Los reemplazos articulares son calificados como procedimientos seguros y exitosos para el tratamiento de la osteoartrosis severa de cadera y rodilla alrededor del mundo. Las tasas de reingreso en los primeros 30 días y las complicaciones se han descrito como una medida para evaluar estándares de calidad. En Colombia no se conoce el comportamiento de éstos estándares. Este estudio pretende aportar información de un centro especializado en reemplazos articulares en Bogotá DC, Colombia, Suramérica. Materiales & Métodos Se realizó un estudio observacional prospectivo de una cohorte de 1.126 pacientes con 626 reemplazos totales de cadera (RTC) y 500 de rodilla (RTR), operados entre los años 2011-2015 en el Hospital Universitario San Ignacio de Bogotá DC, Colombia. Se reportan las tasas de reingreso a 30 días y las complicaciones. Se analiza mediante un modelo de regresión las asociaciones entre variables sociodemográficas y clínicas con el reingreso y las complicaciones. Resultados El 71% de los pacientes fueron mujeres, el promedio de edad de 63 años en los hombres y 65 años en mujeres. La estancia hospitalaria promedio fue de 3,5 días (DE:0,81-6,29). La tasa de reingreso a 30 días por cualquier causa fue 10,8% y la tasa de complicaciones asociadas al procedimiento fue 5,8%, se requirió reintervención quirúrgica en 1,5% de los pacientes. Se encontró asociación estadísticamente significativa entre el índice de Charlson mayor a 2 (OR=2,33[IC95% 1,3-4,18], p=0.004) y el reingreso a 30 días. La principal complicación en RTC fue luxación (1,4%) y en RTR infección de sitio quirúrgico (4%). Se encontró una asociación significativa entre complicaciones a 30 días con los días de hospitalización (OR=1,17[IC95% 1,09-1,25], p=0,00); y con el cirujano 4 en RTR (OR=2,28[IC95% 1,29-4,01], p=0,04); las demás variables no mostraron diferencias significativas. No se aprecian grandes diferencias con lo reportado en la literatura, asociación con estancia hospitalaria y experiencia del cirujano. Discusión La experiencia del cirujano y la aplicación de guías clínicas que optimicen los procesos intrahospitalarios y regulen los días de estancia hospitalaria, se relacionan con un mejor desenlace en la evolución de los pacientes en cuanto al número de complicaciones y reingresos a 30 días.

Background Joint replacements are always defined as safe and successful procedures for the treatment of severe osteoarthritis of the hip and knee around the world. Rates of readmission within initial post surgical 30 days and complications are described as a measure to assess quality standards. In Colombia the behavior of the standards are mainly unknown. Aim of study is to provide information from a specialized in joint replacements center in Colombia. Methods A prospective observational study was carried out on a cohort of 1,126 patients with 626 total hip replacements (THR) and 500 knee replacements (TKR), who underwent surgery between 2011-2015 at a University Hospital in Bogotá, Colombia. 30-day readmission rates and complications were reported. The associations between sociodemographic and clinical variables with readmission and complications were analyzed using a regression model. Results 71% of the patients were women, the average age was 63 years for men and 65 years for women. The mean hospital stay was 3.5 days (SD: 0.81-6.29). The 30-day readmission rate for any cause was 10.8% and the rate of complications associated with the procedure was 5.8%. Additional surgical procedures were required in 1.5% of the patients. A statistically significant association was found between the Charlson index greater than 2 (OR=2.33 [95% CI 1.3-4.18], p=0.004) and readmission at 30 days. The main complication in THR was dislocation (1.4%) and surgical site infection (4%) in TKR. A significant association was found between complications at 30 days and days of hospitalization (OR=1.17 [95% CI 1.09-1.25], p=0.00); and with surgeon 4 in TKR (OR=2.28 [95% CI 1.29-4.01], p=0.04); the other variables did not show significant differences. No differences were found with what is reported in the literature, association with hospital stay and experience of the surgeon. Discussion The surgeon's experience and the application of clinical guidelines that optimize in-hospital processes and regulate the days of hospital stay are related to a better outcome in the evolution of patients in terms of the number of complications and readmissions after 30 days.

Perfil epidemiológico de los pacientes adultos mayores de 65 años con fractura de cadera. Estudio de Cohorte Transversal / Epidemiological profile of adult patients older than 65 years with hip fracture. Cross-sectional study

Introducción Las fracturas de cadera reportan una incidencia en aumento; representan un reto para la salud publica por el alto costo socioeconómico y elevada morbimortalidad. Es importante documentar las complicaciones en la población de Colombia, así como los motivos de reingreso para poder plantear estrategias que contribuyan a disminuirlas. Materiales & Métodos Se realizó un estudio descriptivo, de cohorte transversal, entre enero 2015 y diciembre 2017. Se incluyeron todos los pacientes con fractura de cadera mayores de 65 años. Se excluyeron aquellos con fracturas patológicas y pacientes con antecedente de fractura en esa cadera. Se recolectaron las variables de edad, sexo, antecedentes patológicos, uso de anticoagulantes, manejo farmacológico para osteoporosis, tipo de fractura, complicaciones intraquirúrgicas y postoperatorias, así como el tiempo total desde la fractura hasta el manejo quirúrgico. Resultados Se incluyeron 155 fracturas de cadera con edad promedio de 81.6 años. 74.8% mujeres. El subtipo de fractura más frecuente fue la intertrocantérea (46.5%). El 93.6% de los casos recibió manejo quirúrgico, siendo la artroplastia el procedimiento más realizado. Se realizó manejo quirúrgico en el 85.16% de los pacientes antes de 48 horas y al 40% antes de las 24 horas desde el momento de la fractura. El reingreso fue 20% y la principal causa fueron nuevas fracturas (5.8%). Discusión Se considera el abordaje de los pacientes desde un punto multidisciplinario que maneje sus comorbilidades, fragilidad ósea, debilidad muscular y alteraciones en la esfera mental de forma integral, ya que esto puede afectar positivamente el estado de salud de estos pacientes.

Background Hip fractures are a pathology with an increasing incidence, represent a challenge for public health due to the high socioeconomic cost and high morbidity and mortality. It is important to document the complications in our population, as well as the reasons for readmission to be able to propose strategies that contribute to reducing them. Method A descriptive, cross-sectional, retrospective study was conducted in the period between January 2015 and December 2017. All patients with hip fractures older than 65 years were included. Those with pathological fractures and patients with a history of fracture in that hip were excluded. The variables of age, sex, pathological antecedents, use of anticoagulants, type of fracture, intra-surgical and postoperative complications and total time from fracture to surgical management were collected. Results 155 hip fractures were properly documented, mean age 81.6 years, 74.8% were women. The most frequent fracture was the intertrochanteric (46.5%). 93.6% of the cases received surgical management, being hip arthroplasty the most performed procedure. Surgical management was performed in 85.16% of patients before 48h and 40% before 24h from the time of fracture. The readmission rate was 20% and the main cause was new fractures 5.8% Discussion We consider the approach of patients from a multidisciplinary standpoint that treat the comorbidities, bone fragility, muscle weakness and alterations in the mental sphere, because that may possibly affect the outcome of patients in a positive way.

Methods A retrospective study of 38 patients undergoing primary or revision total hip arthroplasty (THA) using the acetabular dual-mobility cup (DMC) implant between January 2012 and January 2018. The rates of complications and instability after surgery were evaluated. Results In total, 42 arthroplasties were performed in 38 patients, with a minimum follow-up of 16 months. The mean age of the sample was 60 years. In 38 cases, we used a cementless DMC, and, in the other 4 cases, a cemented DMC. There were no cases of early or late instability. Conclusion The series herein presented proves the good result of the DMC in cases of primary arthroplasty, complex and complicated cases of failed osteosynthesis of proximal femoral fractures, and revision for THA instability. The absence of episodes of prosthetic instability and complications in complex cases of primary and revision THA increases the confidence in this concept.

Resumo Objetivo Avaliar a incidência de instabilidade protética em uma série consecutiva de 42 casos de artroplastia total do quadril com uso do acetábulo de dupla mobilidade. Métodos Estudo retrospectivo de 39 pacientes que passaram por artroplastia total de quadril (ATQ) primária ou de revisão usando taça de dupla mobilidade (TDM) acetabular entre janeiro de 2012 e janeiro de 2018. Foram avaliadas as taxas de complicações e de instabilidade após a cirurgia. Resultados Foram feitas 42 artroplastias em 38 pacientes, com um seguimento mínimo de 16 meses. A média de idade da amostra foi de 60 anos. Em 38 casos, usamos TDM sem cimento, e nos outros 4 casos, TDM cimentada. Não houve instabilidade precoce ou tardia. Conclusão A série aqui apresentada prova o bom resultado da TDM em artroplastias primárias, casos complexos e complicados de falha de osteossíntese de fratura proximal do fêmur, e cirurgia de revisão por instabilidade na ATQ. A falta de episódios de instabilidade prostética e complicações em casos complexos de ATQ primária ou de revisão aumentou a confiança nesse conceito.

Cobertura con colgajos de dispositivos ortopédicos en el miembro inferior: experiencia clínica / Covering with Orthopedic Devices Flaps in the Lower Limbs: A Clinical Experience

RESUMEN Introducción: La cobertura de dispositivos ortopédicos expuestos y las infecciones en el hueso con colgajos es un tema controvertido. No existe un consenso claro sobre el tratamiento de esta complicación. En los últimos años se aprecia una tendencia a mantener el material de osteosíntesis y a controlar la infección aportando tejido bien vascularizado en forma de colgajo muscular o fasciocutáneo. Objetivo: Evaluar el éxito reconstructivo con colgajos de defectos de partes blandas en miembros que han precisado de una osteosíntesis, en función de la presencia de infección y el estado de los dispositivos de implante en el momento de la reconstrucción. Métodos: Estudio retrospectivo de una serie de 15 casos con un defecto de partes blandas en las extremidades inferiores secundario a la implantación de dispositivos ortopédicos en el hueso. Todos los casos recibieron cobertura con un colgajo muscular o fasciocutáneo con o sin retirada de los implantes. Se estudió la presencia o ausencia de infección previa a la reconstrucción (signos clínicos, resultado del cultivo microbiológico y exposición del material ortopédico), la retirada o mantenimiento del implante durante la reconstrucción, y la presencia de complicaciones posoperatorias. Se relacionaron estas variables con el éxito reconstructivo posoperatorio. El análisis de las variables se realizó con los estadísticos chi cuadrado, Wilcoxon y U de Mann Whitney, según el tipo de variable, y para una significación de 0,05. Resultados: La frecuencia de éxito reconstructivo fue mayor en aquellos pacientes con cultivo negativo sin exposición de material óseo (p = 0,038). Se encontró menor tasa de complicaciones en los pacientes que presentaban infección antes de la reconstrucción (p = 0,039), y en aquellos con cultivo positivo y exposición del material previos a la cirugía, cuyos implantes habían sido retirados durante la reconstrucción (p = 0,032). Conclusiones: El aporte de tejido bien vascularizado en forma de colgajo permite el mantenimiento del material ortopédico con una frecuencia de éxito de 66,67 %, y resultados favorables de mediano a largo plazo. La exposición y el resultado del cultivo son indicadores predictivos de los resultados de la cirugía(AU)

ABSTRACT Introduction: The covering of exposed orthopedic devices and bone infections with flaps are a controversial issue. There is no clear consensus concerning the treatment of this complication. In recent years, there has been a trend to maintain the osteosynthesis material and to control the infection by providing well vascularized tissue in the form of a muscular or fasciocutaneous flap. Objective: To assess the reconstructive success with flaps of soft tissue defects in limbs that have required osteosynthesis, based on the presence of infection and the status of the implant devices at the time of reconstruction. Methods: Retrospective study of a series of 15 cases with soft tissue defect in the lower limbs after implantation of orthopedic devices to the bone. All the cases were covered with muscle or fasciocutaneous flap, with or without removal of the implants. The presence or absence of infection prior to reconstruction (clinical signs, results of microbiological culture, and exposure of the orthopedic material), removal or maintenance of the implant during reconstruction, and the presence of postoperative complications were studied. These variables were associated with postoperative reconstructive success. The analysis of the variables was performed using the chi-square, as well as Wilcoxon and Mann Whitney U tests, according to the type of variable, and for a significance of 0.05. Results: The frequency of reconstructive success was higher in those patients with negative culture and without exposure of bone material (P=0.038). A lower rate of complications was found in patients with infection before reconstruction (P=0.039), and in those with positive culture and exposure of the material prior to surgery, whose implants had been removed during reconstruction (P=0.032). Conclusions: The provision of well vascularized tissue in the form of flap allows maintenance of the orthopedic material with a success rate of 66.67%, as well as favorable outcomes in the mid to long terms. The results of exposure and culture are predictive indicators of surgery outcomes(AU)

Fractura de cadera y artroplastia en adulta mayor centenaria. Reporte de caso y revisión de literatura / Hip fracture and arthroplasty in centenary elderly. Case report and literature review

La fractura de cadera es una patología cuya incidencia ha aumentado drásticamente en proporción al aumento de la población adulta mayor. En los últimos años, los longevos superan los 100 años y son ellos quienes mayoritariamente presentan esta urgencia trauma-tológica, que casi en la totalidad de los casos se presenta posterior a caídas de bajo impacto y requieren resolución quirúrgica. A continuación, se presenta el caso de una paciente femenina centenaria con fractura de cadera que fue sometida a manejo quirúrgico con posterior recuperación funcional parcial. Se resalta que la edad no es una contraindicación quirúrgica.

Hip fracture is a pathology whose incidence has increased dramatically accordingly with population aging. In recent years, the long-lived have exceeded 100 years. They are who mostly present this traumatic emergency, which almost in all cases occurs after low-impact falls and requires surgical resolution.We expose the case of a centennial female patient presenting with a hip fracture and undergoing surgical orthopaedic repair. She had a partial functional recovery. Our review shows that age is not a surgical contraindication.

Bupivacaine-induced myotoxicity during a continuous perineural femoral block: case report / Miotoxicidad inducida por bupivacaína durante un bloqueo continuo del nervio femoral: reporte de caso

Abstract Introduction: Regional anesthesia is widely used for postopera tive analgesia in total knee arthroplasty (TKA). Although it is a safe and effective procedure, serious complications may still develop. In the event of an unusual or torpid evolution, the possibility of local anesthetic-induced myotoxicity should be suspected. Case presentation: A 54-year old patient, American Society of Anesthesiologists (ASA) II, underwent TKA due to primary gonarthrosis.. The analgesic technique used was a femoral nerve block associated with continuous perineural infusion. 24 hours later, the patient's medical condition deteriorated presenting pain, edema, and functional limitation of the thigh of the operated extremity. The symptoms were suggestive of myotoxicity, confirmed with diagnostic images leading to the removal of the catheter. The patient experienced then a significant improvement and was discharged 5 days after surgery. Conclusion: The diagnosis of myotoxicity from local anes thetics is rare, since its manifestations may be masked by the usual symptoms of the postoperative period. Early identification of the condition is fundamental to reduce its negative impact on the patient's recovery and satisfaction. Since the scope of the damage depends particularly on the concentration and duration of the exposure to the local anesthetic agent, there is a need to implement protocols that enable an effective block with the lowest concentration and volume of the medication.

Resumen Introducción: La anestesia regional es ampliamente usada para la analgesia posoperatoria en la Artroplastia de Reemplazo de Rodilla (ARR). Aunque son procedimientos seguros y efectivos, la posibilidad de complicaciones graves existe. Ante una evolución inusual o tórpida se debe sospechar la posibilidad de miotoxicidad inducida por anestésicos locales. Presentación del caso: En un paciente de 54 años, American Society of Anesthesiologists (ASA) II, se llevó a cabo ARR por gonartrosis primaria. Como técnica analgésica se usó el bloqueo de nervio femoral asociado a infusión continua perineural. 24 horas después el paciente presenta deterioro clínico dado por dolor, edema y limitación funcional en muslo de extremidad operada. Ante síntomas sugestivos de miotoxicidad confirmada por imágenes diagnósticas, el catéter fue retirado. Posteriormente, presentó una mejoría significa tiva y egresó del hospital al quinto día posoperatorio. Conclusiones: El diagnóstico de miotoxicidad por anestésicos locales es poco frecuente debido a que sus manifestaciones pueden estar enmascaradas por los síntomas habituales durante el periodo posoperatorio. Su identificación temprana es funda mental para disminuir el efecto negativo sobre la recuperación y la satisfacción del paciente. Dado que la magnitud del daño depende especialmente de la concentración y la duración de la exposición al anestésico local, es necesario implementar proto colos que permitan lograr un bloqueo efectivo con la menor concentración y volumen posible del medicamento.

Shoulder Arthroplasty: Tenotomy of the Subscapularis Tendon versus the Lesser Tuberosity Osteotomy / Artroplastia de ombro: tenotomia do subescapular versus osteotomia do tubérculo menor

Abstract Objective To evaluate and compare subscapular muscle function among patients undergoing subscapular tenotomy (Group A) and lesser tuberosity osteotomy (Group B), in patients treated with total and partial anatomic shoulder arthroplasty for primary osteoarthrosis. Methods Retrospective study of patients with primary glenohumeral osteoarthrosis surgically undergoing total or partial anatomic shoulder prosthesis implant, evaluated by clinical examination, imaging exams, analogue pain scale and Constant and Murley functional score. A total of 28 patients were evaluated, totalizing a sample of 32 operated shoulders. The minimum follow-up was of 12 months (mean 47.45 months). Results Among patients submitted to subscapularis tendon tenotomy, 10 had an ultrasound with total rupture of its thickness (56%). All of the patients of the group B showed lesser tuberosity healing. There was no difference between groups comparing strength evaluated by Belly press and Bear hug tests as well as clinical outcome, through the Constant and Murley score. Conclusions We did not find differences between Groups A and B evidenciated by comparing strength in the Lift-off test, in the Belly press and Bear hug tests and through he Constant and Murley score.

Resumo Objetivo Avaliar e comparar a função do músculo subescapular entre os grupos submetidos a tenotomia do subescapular (Grupo A) e osteotomia do tubérculo menor (Grupo B), em pacientes tratados por artroplastia anatômica total e parcial de ombros apresentando osteoartrose primária. Métodos Estudo retrospectivo de pacientes portadores de osteoartrose primária glenoumeral tratados cirurgicamente com prótese anatômica total ou parcial de ombro, avaliados por exame clínico, exames de imagens, escala visual analógica de dor e escore funcional de Constant e Murley.

Resultados Nos pacientes submetidos à tenotomia do tendão subescapular, dez obtiveram resultado ultrassonográfico com ruptura de sua espessura total (56%). A consolidação ocorreu em todos pacientes submetidos a osteotomia do tubérculo menor. Não houve diferença entre os grupos na comparação do teste Lift Off, da força nos testes Belly Press e Bear hug, e no escore de Constant e Murley. Conclusões Não encontramos diferença entre os grupos A e B na comparação do teste Lift Off, da força nos testes Belly Press e Bear hug, e no escore de Constant e Murley.

IPACK block: emerging complementary analgesic technique for total knee arthroplasty / Bloqueo IPACK: Complemento analgésico emergente en artroplastia de rodilla

Abstract Introduction: Pain control in total knee arthroplasty (TKA) is a determining factor in the patient's rehabilitation process. With conventional peripheral blocking techniques for the posterior compartment, foot drop, and distal motor deficit have been reported. The infiltration between popliteal artery and capsule of the knee (IPACK) block is a promising emerging analgesic technique. Objective: To describe analgesic control, opioid consumption, and mobility of patients scheduled for TKA using IPACK block as adjunct analgesic to the femoral block. Methods: We conducted a prospective observational cohort study over a 6-month period in adults taken to TKA. Sociodemographic and anthropometric characteristics, laterality, postoperative pain, and opioid consumption, patient and surgeon satisfaction (Likert), postoperative nausea and vomiting, and walk in the first 24hours, were evaluated and reported with a descriptive analysis. Results: Twenty-seven patients taken to TKA received an IPACK block. The pain score remained in a mild level during the 48 hours of evaluation. In 73% of the cases, an opioid rescue dose was not required; 81% of the patients managed to walk in the first 24 hours. Conclusion: The IPACK block, combined with femoral block and neuraxial anesthesia, turn out to be an excellent analgesic strategy for TKA, achieving adequate pain management, prompt rehabilitation, and early ambulation of the patient.

Resumen Introducción: El control del dolor en artroplastia total de rodilla (ATR) es determinante en el proceso de rehabilitación del paciente. Con las técnicas convencionales de bloqueo periférico para el compartimiento posterior se ha reportado pie caído y déficit motor distal. Por lo anterior, se decidió evaluar en una cohorte las cualidades analgésicas del bloqueo IPACK como una técnica emergente prometedora. Objetivo: Describir el control analgésico, consumo de opioides y movilidad de pacientes programados para ATR usando bloqueo IPACK como adyuvante analgésico al bloqueo femoral. Métodos: Se realizó un estudio de cohorte prospectivo, en adultos llevados a ATR, durante 6 meses. Se evaluaron las características sociodemográficas, antropométricas, lateralidad, dolor postopera torio y consumo de opioides, satisfacción del paciente y del cirujano, náuseas y vómito postoperatorio, caminata en las primeras 48 h. Se informar los resultados de forma descriptiva. Resultados: En total, 27 pacientes a quienes se les realizó ATR obtuvieron bloqueo IPACK. La puntuación del dolor se mantuvo en una escala leve en un rango de 1-3 durante las 48 horas de seguimiento. En el 73% de los casos no se requirió una dosis de opioide de rescate. El 81% de los pacientes logró caminar en las primeras 24 horas. Conclusión: El IPACK, combinado con el bloqueo femoral y la anestesia neuroaxial, resultan ser una excelente estrategia analgésica para logar un adecuado control del dolor en ATR, pronta rehabilitación y deambulación temprana del paciente.

Results of Total Cervical Disc Replacement with a Minimum Follow-up of 10 Years / Resultados da artroplastia total de disco cervical com acompanhamento mínimo de 10 anos

Abstract Objective In the present study, we present the results with at least 10 years of follow-up of the cervical disc prosthesis implanted in a single level. Methods Retrospective study of patients undergoing single-level total cervical disc replacement (TCDR). Clinical results included the neck disability index (NDI) and the visual analogue scale (VAS) in the preoperative period, one year postoperatively, and a minimum of 10 years of follow-up. The radiographic parameters included cervical mobility, segmental lordosis, C2-C7 angle, heterotopic ossification (HO), facet and joint degeneration (FJD) and adjacent segment disease (ASD). Results We identified 22 patients, 16 women and 6 men with mean age of 39.7 years old (26-51 years old), of which fifteen completed a minimum follow-up of 10 years. There was a statistically significant improvement of NDI and VAS (p < 0.001) between the preoperative and the postoperative periods (1 year or > 10 years). At the end of 10 years, HO was observed in 59% of the cases. The mobility of the implant was preserved in 80% of the patients. Radiological evidence of ASD was recorded in 6 patients (40%). There was no correlation between the clinical parameters evaluated and the presence of ASD or the different classes of HO. Conclusion Clinical improvement in all evaluated parameters, which persists over time. Most implants maintained mobility, as has already been demonstrated in other studies with shorter follow-ups. In a significant percentage of cases, ASD was observed, questioning the concept of motion preserving technology. However, we did not have any surgical intervention for this reason, since there was no correlation with worse clinical results.

Resumo Objetivo No presente estudo, apresentamos os resultados com um acompanhamento mínimo de 10 anos da artroplastia total do disco cervical (ATDC) em um nível. Métodos Estudo retrospectivo de pacientes submetidos a ATDC em um nível. Os resultados clínicos incluíram o índice de incapacidade relacionada ao pescoço (IIRP) e a escala visual analógica (EVA) no período pré-operatório, um ano pós-operatório e um mínimo de 10 anos de acompanhamento. Os parâmetros radiográficos incluíram a mobilidade cervical, lordose segmentar, ângulo C2-C7, ossificação heterotópica (OH), degeneração facetária e articular (DFA) e doença do segmento adjacente (DSA). Resultados Identificados 22 pacientes, 16 mulheres e 6 homens com média de idade de 39,7 anos (26-51 anos), dos quais 15 tiveram um acompanhamento mínimo de 10 anos. Foi verificada melhoria estatisticamente significativa do IIRP e EVA (p < 0,001) entre pré-operatório e pós-operatório. (1 ano ou > 10 anos). Ao final de 10 anos, OH foi observada em 59% dos casos. A mobilidade do implante foi preservada em 80% dos pacientes. Houve evidência radiológica de DSA em 6 pacientes (40%). Não houve correlação entre os parâmetros clínicos avaliados e a presença de DSA ou as diferentes classes de OH. Conclusão Melhoria clínica em todos os parâmetros avaliados, que persiste ao longo do tempo. A maioria dos implantes manteve a mobilidade, como já demonstrado em estudos anteriores com acompanhamentos mais curtos. Numa percentagem significativa, a DSA estava presente, questionando o conceito da tecnologia de preservação de movimento. No entanto, sem nenhuma intervenção cirúrgica por esse motivo, uma vez que não houve correlação com piores resultados clínicos.

Schwannoma anciano del nervio obturador: una rara causa de neuralgia / Ancient schwannoma of the obturator nerve: an uncommon cause of pelvic neuralgia

Los tumores retroperitoneales son lesiones infrecuentes. Las tumoraciones nerviosas benignas como los schwannomas representan menos del 3% de ellos, siendo extremadamente raros los que afectan el nervio obturador. Presentamos el caso de un paciente con importante afectación funcional en miembro inferior izquierdo y dolor pélvico, al que se le diagnosticó neoplasia retroperitoneal. Fue intervenido por vía laparoscópica objetivándose la dependencia de la lesión del nervio obturador. Se llevó a cabo una exéresis completa de la lesión preservando parcialmente el nervio. El paciente tuvo una evolución funcional y álgica muy favorable. La anatomía patología reveló la presencia de schwannoma, del denominado subtipo "anciano", sin datos de malignidad. Consideramos que el informe de un caso como este puede ayudar a conocer una patología muy infrecuente y a tener en consideración algunos puntos clave como la técnica de abordaje y la necesidad de preservación de las estructuras nerviosas.

Retroperitoneal tumors are uncommon; benign tumors originating in the nerve cells as schwannomas represent less than 3%, while schwannomas of the obturator nerve are extremely rare. We report the case of a male patient with significant functional compromise of the left lower limb and pelvic pain who was diagnosed with a retroperitoneal tumor. The patient underwent laparoscopic surgery during which the compromise of the obturator nerve was evident. The lesion was completely resected with partial preservation of the nerve. The patient progressed with favorable functional recovery and pain relief. The histopathological examination reported a benign ancient schwannoma. We believe that this case report can help to understand a very rare condition and consider some key points such as the technique of approach and the need for preservation of the nerve structures.
