ABSTRACT

La fijación de luxaciones acromioclaviculares de alto grado con métodos de cerclaje coracoclavicular exige una manipulación cuidadosa del instrumental y de los dispositivos de fijación como suturas o injertos a nivel subcoracoideo. La estrecha relación de la apófisis coracoides con el plexo braquial y la arteria axilar hace que esta sea una zona riesgosa y técnicamente demandante durante la cirugía. Para esta instancia, se han desarrollado dispositivos específicos, pero pueden ser costosos y poco disponibles. Se presenta una técnica manual, reproducible, segura y sencilla, que evita el uso de dispositivos adicionales para realizar cerclaje coracoclavicular en fijación o reconstrucción acromioclavicular.


Stabilization of high-grade acromioclavicular dislocations with coracoclavicular cerclage methods requires careful manipulation of instruments and fixation devices when approaching the coracoid process. This is risky and technically challenging surgical area due to the close relationship with the brachial plexus and the axillary artery. Specific devices have been developed for this instance, but they can be expensive and rarely available. A reproducible, safe and simple manual technique is presented, which avoids the use of additional devices to perform coracoclavicular cerclage in acromioclavicular fixation or reconstruction.

ABSTRACT

ABSTRACT Objective: To describe the upper and lower blepharoplasty technique associated with canthopexy with double pre septal orbicularis muscle elevation with a single suture in order to evaluate the efficacy of the technique. Methods: This is a retrospective study in which the medical records of 5,882 patients who underwent this technique between January 1999 and July 2015 were evaluated. The frequency and main causes of clinical complications and surgical reoperation were analyzed. Results: The incidence of complications found was 12.7% (n=750), being 0.8% (n=47) due to persistent chemosis, 3% (n=176) due to poor lower eyelid positioning, 4.17% (n=245) due to mild eyelid retraction and 4.8% (n=282) because of mild to moderate chemosis. Conclusion: The technique appears to be effective as it is simple and practical, and capable of resulting in positive functional and aesthetic outcomes with low rates of complications.

ABSTRACT Introduction: The suture line dehiscence is one of the most frequent complications in intestinal surgery. Objective: To design a predictive scale for estimating individual probability of suture line dehiscence. Methods: An analytical cohort study, which involved retrospective data collection, was carried out, in the six-year period of 2014-2019, at Celia Sánchez Manduley Hospital. The sample consisted of 437 patients. Dehiscence of the intestinal suture line was used as a dependent variable, while age, sex, comorbidity, hemoglobin, hypoalbuminemia, colon neoplasia, anesthetic risk, among others, were used as independent variables. Results: Through multivariate analysis, an adjusted model was obtained, with the following results for the variables: age over 70 years (P=0.002), hypoalbuminemia (P=0.014), enterocolic anastomosis (P=0.018), urgent surgery (P=0.001), and ileus prolonged paralytic (P < 0.001). The predictive scale was derived from the adjusted statistical model and, based on the probability of dehiscence of the intestinal suture line, classified into three risk groups: low (less than two points), moderate (between 3-5 points) and high (more than six points). It presented a sensitivity of 89.6 percent, a specificity of 89.1 percent, a global predictive percentage of 89.2 percent, a positive predictive value of 66.1 percent, and a negative predictive value of 97.2 percent. It had an excellent calibration and a high discriminative power. Conclusion: A predictive scale was obtained for estimating the individual probability of dehiscence of the intestinal suture line(AU)

ABSTRACT

Relata-se o caso de uma felina, sem raça definida, de oito meses de idade e 3,6 kg, com queixa de impotência funcional completa do membro pélvico esquerdo após trauma. A paciente apresentava aumento de volume em região do joelho, dor à palpação e instabilidade patelar. O diagnóstico de ruptura do ligamento patelar foi realizado com base nos resultados do exame ortopédico, juntamente com exame radiográfico e ultrassonográfico do joelho. O método utilizado para reparo da lesão foi a sutura em oito com fio de tetrafluorcabono associado à sutura interrompida simples para aproximação das bordas do ligamento. Durante a reavaliação de trinta dias pós-operatório, a paciente já apresentava melhora significativa, com atividade funcional completa do membro e ausência de dor.


We report the case of an eight-month-old, 3.6 kg, crossbred feline, complaining of complete functional impotence of the left pelvic limb after trauma. The patient presented swelling in the knee region, pain on palpation and patellar instability. The diagnosis of patellar ligament rupture was based on the results of the orthopedic examination, together with radiographic and ultrasound examinations of the knee. The method used to repair the lesion was eight-point suture with tetrafluorocabono thread associated with simple interrupted suture for approximation of the ligament edges. During the thirty-day postoperative reassessment, the patient already presented significant improvement, with complete functional activity of the limb. and absence of pain.

ABSTRACT

OBJETIVO:Comparar el promedio de curva de presión de contacto y el porcentaje de presión de contacto residual final en la interfase tendón-huella de una reparación transósea (TO) realizada con nudos cruzados y una configuración Mason-Allen modificada (MAM). MÉTODOS: Se utilizaron ocho hombros de cordero para simular una rotura de manguito rotador. Se midió la presión con un sensor digital. Se registró la presión basal durante la aplicación de carga cíclica y al final de la intervención. Se compararon dos reparaciones: dos túneles TOs con nudos cruzados (TOCs) (n » 4) y dos puntos MAMs (n » 4) utilizando suturas MaxBraid #2 (Zimmer Biomet, Warsaw, IN, EEUU). Se realizaron 1.000 ciclos, con una frecuencia de 2 Hz y una carga de 30 N. Se utilizó el test de t de Student, y se consideraron significativos valores de p < 0,05. RESULTADOS: El promedio de curva de presión de contacto en las piezas que fueron reparadas con suturas TOCs fue de 86,01 8,43%, mientras que con MAM fue de 73,28 12,01% (p < 0,0004). El promedio del porcentaje residual al final del ciclado fue de 71,57% para suturas TOCs y de 51,19% para MAM (p < 0,05). CONCLUSION: La reparación TOC presenta mayor promedio de curva de presión de contacto y mayor porcentaje de presión de contacto residual final en la interfase tendón-huella que la reparación con sutura MAM luego de carga cíclica estandarizada, lo que podría traducirse en una mejor cicatrización del tendón. NIVEL DE EVIDENCIA: Estudio de ciencia básica.


OBJECTIVE: To compare the average contact pressure curve and the percentage of final residual contact pressure at the tendon-footprint interphase of a transosseous (TO) repair performed with crossover sutures or a modified Mason-Allen (MMA) configuration. METHODS: Eight lamb shoulders were used to simulate a rotator cuff tear. The pressure was measured with a digital sensor. The baseline pressure was recorded during the application of the cyclic load and at the end of the intervention. Two repairs were compared: 2 crossover TO (CTO) sutures (n » 4) and 2 MMA sutures MMA (n » 4), using MaxBraid #2 (Zimmer Biomet, Warsaw, IN, US) sutures. A thousand cycles were performed, with a frequency of 2 Hz and a 30-N load. The Student t-test was used, and significance was set at p < 0.05. RESULTS: The average contact pressure curve was of 86.01 8.43% for parts repaired with CTO sutures, and of 73.28 12.01% for those repaired with MMA sutures (p < 0.0004). The mean residual percentage at the end of cycling was of 71.57% for CTO sutures, and of 51.19% for MMA sutures (p < 0.05). CONCLUSION: The CTO repair shows a higher average contact pressure curve and a higher percentage of final residual contact pressure at the tendon-footprint interphase than the MMA suture repair after standardized cyclic loading, potentially resulting in improved tendon healing. LEVEL OF EVIDENCE: Basic Science Study.

ABSTRACT

OBJECTIVE@#To compare and analyze the mechanical differences between single-row suture anchor fixation for repairing rotator cuff injuries and double-row suture bridges for repairing rotator cuff injuries from a biomechanical perspective.@*METHODS@#The CT scan data of healthy adult shoulder joint were imported into Mimics, Geomagics and Hypermesh to carry out reverse reconstruction of two repair models, material assignment and mesh division, and the tearing of supraspinatus muscle was designed. After treatments, the load and boundary conditions were applied to the shoulder joint in ABAQUS software. The shoulder joint was fixed with four working conditions including flexion 15 °, flexion 30 °, internal rotation 15 ° and internal rotation 30 ° after anchor fixationand repair. The stress changes of the upper rotator cuff muscle and the anchor with thread were compared under these four conditions.@*RESULTS@#Under the two flexion conditions, the stress of the supraspinatus in the double row suture bridge fixation model was 8.3% and 12% less than that in the single-row suture anchor fixation, respectively. Under the two internal rotation conditions, the stress of supraspinatus in the double row suture bridge fixation model was 47% and 48% less than that in the single row fixation repair model, respectively.@*CONCLUSION@#The "load sharing" effect between the two rows of four anchors makes the stress distribution more dispersed, increases the contact area between the supraspinatus muscle and the humerus, reduces the stress of the anchor, avoids the serious stress concentration phenomenon, and explains the advantages of the fixation method of the double row suture bridge from the biomechanical angle.

ABSTRACT

Shoulder arthroscopic as a conventional method usually is applied to repair rotator cuff tears. In clinical, plenty single-row, double-row and transosseous tunnels suture technique are performed, but the ideal suture technique for rotator cuff repair is not found. Compared with single-row, double-row has better strength in biomechanics property. As the two best suture technique among the single-row, massive cuff stitch and modified Mason-Allen suture have the strongest biomechanics property. Clinical trials indicate that double-row could improve healing rates, but there are no significant difference in clinical outcome functional scores. Transosseous tunnel techniques possess a better bio-mechanic property, which could improve regional micro-environment and induce tendon-bone healing. Transosseous tunnel techniques are better for small to media size rotator cuff tears and osteoporosis patient. The author suggest that optimal rotator cuff repair technique should performed according to skill of performer and individual of patient by analysing bio-mechanic properties, clinical outcome, operative complexity and patient situation. The technique should follow simple opertaion, rapid, less trauma, stable fixation and utility to perform.

Material and Methods: In total, 30 patients ranging between 18-30 years of age and of either sex who had bilaterally impacted mandibular third molars were randomly selected. Split mouth study method was used so that the participants served as their own control. Group 1 consisted of primary closure of left mandibular impacted third molars and Group 2 consisted of secondary closure of right mandibular impacted third molars. Basement evaluations were recorded for each patient along with subjective and objective evaluations for postoperative 7 days. Data analysis was carried out by SPSS 17.0 software using Mann-Whitney U test, Wilcoxon matched-pairs test and t-test. A p-value ≤ 0.05 was assigned as statistically significant. Results: When compared to group 1, group 2 revealed statistically less pain and swelling following the secondary closure of wound from day 1 to 7. There was a significant improvement in mouth opening in Group 2 at day 1 (p=0.0005) and at day 7 (p=0.00001). Conclusion: Secondary wound closure after disimpaction of mandibular third molar results in better postoperative recovery than primary closure.

ABSTRACT

OBJECTIVES: In the present study, a novel single knot tenorrhaphy was developed by combining the modified Kessler flexor tendon suture (MK) with the loop lock technique. METHODS: A total of 48 porcine flexor digitorum profundus tendons were collected and randomly divided into six groups. The tendons were transversely cut and then repaired using six different techniques, the MK method, double knot Kessler-loop lock flexor tendon suture (DK), and single knot Kessler-loop lock flexor tendon suture (SK), each in combination with the epitendinous suture (P), and the same three techniques without P. Furthermore, by performing the load-to-failure tests, the biomechanical properties and the time taken to complete a repair, for each tenorrhaphy, were assessed. RESULTS: Compared to the MK+P method, DK+P was more improved, thereby enhancing the ultimate tensile strength. The SK+P method, which required fewer knots than DK+P, was easier to perform. Moreover, the SK+P repair increased the force at a 2-mm gap formation, while requiring lesser knots than DK+P. CONCLUSION: As opposed to the traditional MK+P method, the SK+P method was improved and exhibited better biomechanical properties, which may facilitate early mobilization after the repair.

ABSTRACT

Introducción: las luxaciones acromioclaviculares son frecuentes en los servicios de urgencias de ortopedia, en su gran mayoría reciben un tratamiento conservador, sin embargo, para aquellas que requieren de manejo quirúrgico no existe una técnica estándar con adecuados resultados a largo plazo. El objetivo fue describir el abordaje quirúrgico con la técnica de estabilidad bidimensional con supersuturas en luxaciones acromioclaviculares agudas y reportar los desenlaces funcionales, radiológicos y complicaciones en el postoperatorio utilizando esta técnica. Materiales y métodos: se trata de un estudio descriptivo de series de casos, realizado en dieciocho pacientes con diagnóstico de luxación acromioclavicular aguda (menor de dos semanas) entre enero de 2015 a noviembre de 2019 en dos instituciones de Bogotá, Colombia. Evaluando la funcionalidad con el cuestionario DASH, se realizó un análisis radiológico tomando radiografías comparativas de la articulación acromioclavicular teniendo en cuenta la distancia acromioclavicular y coracoclavicular en el postoperatorio inmediato, al mes y después de los seis meses. Resultados: como resultados posteriores a la intervención quirúrgica se encontraron puntajes óptimos con resultados satisfactorios en el cuestionario de evaluación funcional (95% con puntajes por debajo de 15 puntos a los seis meses de evaluación con una mediana de 3.7 en escala de 0-100) y hallazgos imagenológicos postoperatorios con esta técnica quirúrgica con baja incidencia de complicaciones (dos pacientes con dolor y uno con hiperestesia de la zona intervenida). Conclusión: en conclusión, la técnica quirúrgica de estabilidad bidimensional con supersuturas presenta resultados satisfactorios de funcionalidad con baja frecuencia de complicaciones siendo de gran valor para el manejo de lesiones acromioclaviculares agudas


Introduction: acromioclavicular dislocations are frequent in orthopedic emergency services, the vast majority receive conservative treatment, however, in those that require surgical management there is no standard technique with adequate long-term results. The objective was to describe the surgical approach with the two-dimensional stability technique with supersutures in acute acromioclavicular dislocations and to report the functional and radiological outcomes and complications in the postoperative period using this technique. Materials and methods: this is a descriptive study of case series, carried out in eighteen patients with a diagnosis of acute acromioclavicular dislocation (less than two weeks) between January 2015 and November 2019 in two institutions in Bogotá, Colombia. Evaluating the functionality with the DASH questionnaire, a radiological evaluation was carried out taking comparative radiographs of the acromioclavicular joint, considering the acromioclavicular and coracoclavicular distance, in the immediate postoperative period, at one month and after six months postoperatively. Results: after the surgical intervention, optimal scores were found with satisfactory results in the functional evaluation questionnaire (95% with scores below 15 points at six months of evaluation with a median of 3.7 on a scale of 0-100) and findings postoperative imaging with this surgical technique with a low incidence of complications (two patients with pain and one with hyperesthesia of the intervened area). Conclusion: the two-dimensional stability surgical technique with supersutures presents satisfactory results of functionality with a low frequency of complications, being of great value for the management of acute acromioclavicular injuries

ABSTRACT

Twelve dogs with traumatic hip luxation were selected for surgical intervention with a modified iliofemoral suture technique using an anchor screw to substitute the passage of suture material through a perforated tunnel in the ilium. Six procedures were performed with non-absorbable suture and other six with absorbable suture materials. These cases were evaluated at 15, 30, 60, and 90 days after surgery by performing an ambulation analysis and palpation of the joint. In all cases, there was a return of partial and total limb support in an average of 3 and 19 postoperative, respectively. The fixation strategy of the suture material in the ilium using an anchor screw proved to be efficient with a smaller surgical approach and lesser surgical difficulty, maintaining joint congruence in acute as chronic luxation cases. The use of absorbable and non-absorbable sutures had excellent clinical results, but there was a subjective superiority of the first ones, once 4 dogs of the non-absorbable group presented some discomfort during the postoperative palpation of the joint, 90 days after surgery.(AU)


Doze cães com luxação coxofemoral traumática foram submetidos à intervenção cirúrgica de sutura iliofemoral modificada com uso de parafuso âncora substituindo a passagem de fio através de túnel perfurado no ílio. Seis procedimentos foram realizados com fio não absorvível, e outros seis com fio absorvível. Os casos foram avaliados aos 15, 30, 60 e 90 dias após a cirurgia, por meio de análise de deambulação e palpação articular. Em todos os casos, houve retorno de suporte parcial e total do peso no membro operado, em média, aos três e 19 dias de pós-operatório, respectivamente. A estratégia de fixação do fio de sutura no ílio com parafuso âncora se mostrou eficaz, permitindo uma abordagem cirúrgica menos invasiva, com menor dificuldade na execução, garantindo manutenção da congruência articular tanto em quadros de luxação aguda como crônica. O uso de fio absorvível e não absorvível teve bons resultados clínicos, porém houve uma superioridade subjetiva do primeiro, uma vez que quatro pacientes do grupo fio inabsorvível mostraram desconforto à palpação da articulação aos 90 dias após a cirurgia.(AU)

ABSTRACT

Abstract Objective To evaluate different femoral fixation devices for medial patellofemoral ligament reconstruction and compare their effectiveness regarding fixation strength up to failure in porcine knees. Methods Thirty porcine knees were used, divided into three groups of 10 knees. The removed grafts were dissected from the extensor tendons of porcine feet. In each group, the graft was fixed to the femur with an interference screw, an anchor, or adductor tenodesis. The three methods were subjected to biomechanical tests using a universal Tensile testing machine at a speed of 20 mm/minute. Results The highest average linear resistance under lateral traction occurred in group 1, "screw fixation" (185.45 ± 41.22 N), followed by group 2, "anchor fixation" (152.97 ± 49, 43 N); the lower average was observed in group 3, "tenodesis fixation" (76.69 ± 18.90 N). According to the fixed error margin (5%), there was a significant difference between groups (p < 0.001); in addition, multiple comparison tests (between group pairs) also showed significant differences. Variability was small, since the variance coefficient was lower than 33.3%. Conclusion Interference screws in bone tunnels and mountable anchors fixation with high resistance wire are strong enough for femoral fixation in porcine medial patellofemoral ligament reconstruction. Adductor tenodesis, however, was deemed fragile for such purpose.


Resumo Objetivo Avaliar diferentes dispositivos de fixação femoral na reconstrução do ligamento patelofemoral medial para comparar sua eficácia quanto à força de fixação até a falha em joelhos suínos. Métodos Foram ensaiados 30 joelhos de suínos subdivididos em 3 grupos de 10 joelhos. Os enxertos retirados foram dissecados de tendões extensores das patas dos suínos. Cada grupo teve o enxerto fixado ao fêmur com parafuso de interferência, âncora, ou tenodese no tendão adutor. Os 3 métodos foram submetidos à testes biomecânicos utilizando uma máquina universal de ensaio de tração com uma velocidade de 20 mm/min. Resultados Verificamos que a média mais elevada da resistência linear sob tração lateral (185,45 ± 41,22 N) ocorreu no grupo 1: "fixação por parafuso," seguido do grupo 2: "fixação por âncora" (152,97 ± 49,43 N), e a média foi menor no grupo 3: "fixação por tenodese" (76,69 ± 18,90 N). Para a margem de erro fixada (5%), comprovou-se a diferença significativa entre os grupos (p < 0,001) e também através dos testes de comparações múltiplas (entre os pares de grupos) verificou-se a ocorrência de diferenças significativas. A variabilidade expressada por meio do coeficiente de variação mostrou-se reduzida, já que a referida medida foi inferior a 33,3%. Conclusão O uso de parafusos de interferência no túnel ósseo de joelhos porcinos é suficientemente forte para fixação femoral na reconstrução do ligamento patelofemoral medial, assim como a fixação com âncoras montáveis com fio de alta resistência. Entretanto, a tenodese no tendão adutor mostrou-se frágil para essa finalidade.
