La artritis séptica acromioclavicular es un cuadro sumamente infrecuente que, por lo general, se presenta en articulaciones con alta vascularización, como cadera, rodilla y hombro. El microorganismo aislado con más frecuencia es Staphylococcus aureus. Describimos a una paciente de 56 años con artritis séptica acromioclavicular, que requirió una intervención quirúrgica de urgencia. Otra particularidad del caso es el germen aislado, Staphylococcus argenteus, una bacteria muy infrecuente en este tipo de enfermedad. Nivel de Evidencia: IV

Acromioclavicular septic arthritis is an extremely rare condition that usually occurs in highly vascular joints such as the hip, knee, and shoulder. The most frequently isolated pathogen is Staphylococcus aureus. In this presentation we describe a 56-year-old patient with septic arthritis at the acromioclavicular level, requiring emergency surgical intervention. As another peculiarity, the isolated germ was Staphylococcus argenteus, an extremely rare bacterium in this type of pathology. Level of Evidence: IV

Las luxaciones acromioclaviculares son lesiones frecuentes del hombro en jóvenes y deportistas. Luego de tres semanas del trauma inicial, las estructuras ligamentarias tienen un pobre potencial biológico de cicatrización. Por este motivo, en los casos en los que no se diagnostica oportunamente y/o el tratamiento conservador no es exitoso, debe enfrentarse esta dificultad con una técnica de reconstrucción ligamentaria. Para ello, el uso de injertos, además de optimizar la estabilidad mecánica de la reducción de la luxación, mejora la capacidad biológica de cicatrización. Sin embargo, hasta el momento no existe una técnica estandarizada ni un patrón de oro para el tratamiento quirúrgico reconstructivo de las luxaciones crónicas acromioclaviculares. Se presenta una síntesis de la literatura más reciente y disponible sobre el uso de diferentes tipos de injertos en reconstrucción de luxación acromioclavicular. Nivel de Evidencia: V

Acromioclavicular dislocations are common shoulder injuries in young people and athletes. After three weeks of the initial trauma, the ligament structures have a poor biological healing potential. For this reason, in cases of late diagnosis or unsuccessful conservative management, this difficulty must be addressed with a ligament reconstruction technique. The use of grafts, in addition to optimizing the mechanical stability of the reduction, improves the biological healing capacity. However, to date there is no gold standard among the many techniques described for reconstructive surgical treatment of chronic acromioclavicular dislocations. A synthesis of the most recent literature available on the use of different types of grafts in reconstruction of acromioclavicular dislocation is presented. Level of Evidence: V

OBJECTIVE@#To evaluate the efficacy and prognosis of double button plate combined with strengthened anchor technique and clavicular hook plate internal fixation for complete acromioclavicular joint dislocation.@*METHODS@#From July 2017 to September 2020, a total of 42 patients with acromioclavicular joint dislocation treated by surgery were choosen as study objects and divided into observation group (21 cases) and control group (21 cases). In the observation group, there were 14 males and 7 females, aged 21 to 63 years old, with an average of (45.05±8.70) years old. In the control group, there were 16 males and 5 females, aged 25 to 68 years old, with an average of(45.00±9.44) years old. The patients in the observation group were treated with double button plate combined with strengthened anchor technique, whereas those in the control group received clavicular hook plate internal fixation. The two groups were compared in terms of operating time, intraoperative blood loss, postoperative hospital stay, shoulder pain(visual analogue scale, VAS) score, shoulder function Constant-Murley score and postoperative complications.@*RESULTS@#There was no significant difference between the two groups in intraoperative blood loss or postoperative hospital stay(P>0.05). The operating time of double button plate combined with strengthened anchor technique group (65.24±5.36) min was significantly longer than that of the clavicular hook plate group (48.81±4.72) min, and the difference was statistically significant (P<0.05). There was no significant difference in shoulder function or pain degree between the two groups before operation (P>0.05). After 1 month, 3 months and 6 months, the Constant-Murley score of the observation group was 73.29±2.15, 85.43±1.47, 93.86±1.24 separately, which were significantly higher than those of the control group;and the VAS score was 2.76±0.62, 1.71±0.64, 0.57±0.51 separately, which were significantly lower than those of the control group (P<0.05). One instance of shoulder discomfort was found in the observation group, while 5 cases of shoulder pain, 2 cases of restricted shoulder mobility, and 1 case of subacromial bone absorption were found in the control group. In both group, there was no loss of reduction.@*CONCLUSION@#In the treatment of complete acromioclavicular joint dislocation double button plate combined with strengthened anchor technique achieves favorable clinical result. Internal fixation does not need to be removed. The recovery of shoulder joint function and pain relief are superior than clavicular hook plate internal fixation, which is more worthy of clinical promotion.

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

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

Abstract Objectives The present study evaluates and compares the surgical treatment of acute and chronic acromioclavicular dislocations (ACDs) to define the most effective therapeutic plan. Methods A retrospective study consisting of 30 patients submitted to the surgical treatment of types III and V ACDs between 2011 and 2018; the subjects were separated according to a temporal classification in acute (< 3 weeks; subgroup I) and chronic (> 3 weeks; subgroup II) subgroups. All patients underwent a postsurgical evaluation with a standardized protocol containing epidemiological, functional, and radiological data. Results Subgroup I presented a visual analog scale (VAS) score of 1.10, a Constant-Murley score of 92.3, and a University of California at Los Angeles (UCLA) Shoulder Rating score of 33.5. The coracoclavicular (CC) distance was of 11.0 mm, and the average increase in CC space was lower than 8.9% compared to the contralateral shoulder. In subgroup II, the VAS score was of 1.11, the Constant-Murley score was of 94.2, and the UCLA score was of 32.4. The CC distance was of 13.8 mm, with a 22.9% increase in CC space compared to the contralateral side. Conclusion Although there was no significant difference between the evaluated items, subgroup I tended to present a lower CC distance (p = 0.098) and a lower percentage increase in CC distance (p = 0.095) compared to subgroup II. Thus, the surgical treatment must be performed within three weeks after the trauma to try to avoid such trend. If the acute treatment is not possible, the modified Weaver Dunn technique has good clinical and functional outcomes.

Resumo Objetivos Avaliar e comparar os resultados do tratamento cirúrgico das luxações acromioclaviculares (LACs) aguda e crônica, definindo o plano terapêutico mais eficaz. Métodos Estudo retrospectivo realizado com 30 pacientes operados entre 2011 e 2018 para LAC tipos III e V, separados de acordo com a classificação temporal em subgrupo agudo (< 3 semanas; subgrupo I) e subgrupo crônico (> 3 semanas; subgrupo II). Todos os pacientes foram submetidos a avaliação pós-cirúrgica com protocolo padronizado composto por dados epidemiológicos, funcionais e radiográficos. Resultados No subgrupo I, a pontuação na escala visual analógica (EVA) foi de 1,10, o escore de Constant-Murley foi de 92,3, e o escore da University of California at Los Angeles (UCLA) foi de 33,5. A distância coracoclavicular (CC) foi de 11,0 mm, e o aumento do espaço CC foi em média menor do que 8,9% em relação ao ombro contralateral. No subgrupo II, a EVA foi de 1,11, o escore de Constant-Murley foi de 94,2, e o da UCLA, 32,4. A distância CC foi de 13,8 mm, sendo o aumento do espaço CC de 22,9% em relação ao contralateral. Conclusão Apesar de não ter havido diferença significativa entre os quesitos avaliados, houve uma tendência de o subgrupo agudo apresentar distância CC (p = 0,098) e percentual de aumento da distância CC (p = 0,095) menor do que o subgrupo crônico. Assim, é interessante que o tratamento cirúrgico seja realizado nas primeiras três semanas após o trauma, para tentar evitar essa tendência. Nos casos em que não for possível realizar o tratamento na fase aguda, a técnica de Weaver Dunn modificada apresenta bons resultados clínicos e funcionais.

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

OBJECTIVE@#To study the clinical efficacy and complications of Endobutton titanium plate and clavicle hook plate in the treatment of acromioclavicular dislocation.@*METHODS@#Total 48 patients with Rockwood Ⅲ to Ⅴ acromioclavicular joint dislocation from March 2015 to May 2019 were retrospectively divided into two groups according to different surgical methods. Among the patients, 23 patients were treated with Endobutton loop titanium plate fixation (observation group), including 15 males and 8 females, ranging in age from 23 to 59 years old, with an average of(36.2±8.1) years old;Rockwood type Ⅲ in 6 cases, type Ⅳ in 11 cases and type Ⅴ in 6 cases. Twenty-five patients were treated with clavicular hook plate(control group), including 17 males and 8 females, ranging in age from 22 to 54 years old, with an average of (34.7±6.4) years old; Rockwood type Ⅲ in 6 cases, type Ⅳ in 14 cases and type Ⅴ in 5 cases. The operation time, intraoperative bleeding, hospitalization time, visual analogue scale (VAS) of pain, Constant-Murley score of shoulder function and postoperative complications were compared between the two groups.@*RESULTS@#All the patients were followed up, and the duration ranged from 24 to 51 months, with a mean of (30.5±6.5) months. The amountof bleeding and hospitalization time in the observation group were (71.9±4.0) ml and(8.2±1.6) d respectively;and those in the control group were (97.6±13.4) ml and (12.8±1.2) d respectively. There was significant difference between the two groups (@*CONCLUSION@#Compared with clavicular hook plate internal fixation in the treatment of acromioclavicular joint dislocation, Endobutton loop titanium plate internal fixation technology has the advantages of less surgical bleeding, shorter hospitalization time, less postoperative pain, good recovery of shoulder joint function and less complications.

OBJECTIVE@#To compare the clinical efficacy of titanium cable biomimetic reconstruction of coracoclavicular ligament and clavicular hook plate in the treatment of acromioclavicular joint dislocation.@*METHODS@#The clinical data of 39 patients with severe acute acromioclavicular joint dislocation from January 2017 to December 2018 were retrospectively analyzed, 19 patients in double strand titanium cable group, including 13 males and 6 females, aged from 26 to 67 years old; Rockwood classification:10 cases of type Ⅲ, 4 cases of type Ⅳ and 5 cases of type Ⅴ;8 cases of traffic injury and 11 cases of fall injury;the time from injury to operation was 3 to 6 days. There were 20 patients in steel plate group, including 15 males and 5 females, aged from 25 to 71 years old. Rockwood classification:11 cases of type Ⅲ, 4 cases of typeⅣ, 5 cases of type Ⅴ;7 cases of traffic injury, 13 cases of fall injury;the time from injury to operation was 2 to 7 days. The length of incision, operation time, intraoperative blood loss, cost, VAS score before and after operation, and Constant-Murley score before and after operation were compared between two groups. Postoperative X-ray films were taken to observe the reduction and maintenance of acromioclavicular joint dislocation. Complications were recorded.@*RESULTS@#Thirty-six patients were followed up for 12 to 14 months. The amount of intraoperative blood loss in the two groups was basically the same. The operation incision in double strand titanium cable group was shorter, the operation time in steel plate group was shorter, and the operation cost in double strand titanium cable group was less. One week and one year after operation, the pain of double strand titanium cable group was less than that of steel plate group. One year after operation, the Constant-Murley score of double strand titanium cable group was higher than that of steel plate group. The postoperative X-ray showed that the acromioclavicular joint in double strand titanium cable group was well reduced, and there was 1 case with slight reduction loss. In the plate group, there was no reduction loss after removal of the clavicular hook plate, and 8 patients had distal clavicular bone atrophy or acromion bone resorption. In steel plate group, 4 cases had long-term postoperative pain, postoperative dysfunction and other complications.@*CONCLUSION@#The clinical effect of coracoclavicular ligament reconstruction with double strand titanium cable is better than that of clavicular hook plate in the treatment of severe acute acromioclavicular joint dislocation, with less trauma (no secondary operation) and lower cost.

OBJECTIVE@#To investigate the clinical effect of arthroscopic assisted TightRope plate, Triple-Endobutton plate and Double Endobutton plate in treating of Rockwood type Ⅲ-Ⅴ acromioclavicular dislocation.@*METHODS@#From January 2014 to January 2018, 128 patients with acromioclavicular dislocation were treated by operation. According to the operation plan, the patients were divided into three groups:Double Endobutton group, Triple-Endobutton group and TightRope group. All patients with acromioclavicular dislocation were operated by the same operation team, and the chief surgeon was the same chief physician. General baseline data such as gender, age, operation time, incision length, intraoperative blood loss, VAS score of pain and Constant-Murley shoulder function score were recorded.@*RESULTS@#The wound healed well and no recent complications occurred. One hundred and eleven patients were followed up for 6 to 12(9.1±3.1) months. There was no significant difference on general data among three groups (P >0.05). Among three groups, the operation time of Triple -Endobutton group was the longest, significantly higher than that of other two groups(<0.05);the operation time of TightRope group was the shortest, significantly lower than that of other two groups (<0.05). At 1 month after operation, VAS score comparison of three groups, TightRope group was significantly lower than other two groups, with statistical difference (<0.05). At 12 months after operation of three groups, the Constant-Murley score of TightRope group was significantly higher than that of two group (<0.05). The incidence of incision infectionin TightRope group was significantly lower than that of other two groups(<0.05); the incidence of reduction loss in Double Endobton group was significantly higher than that of other two groups(<0.05), the incidence of reduction loss in TightRope group was significantly higher than that of Triple endobton group(<0.05);the incidence of joint adhesion in TightRope group was significantly lower than that of other two groups(<0.05).@*CONCLUSION@#TightRope plate fixation with arthroscopy is more advantageous than Double Endobutton plate fixation and Triple-Endobutton plate fixation.

OBJECTIVE@#To explore the clinical effect of the modified double Endobutton technique combined with Nice node in the treatment of Rockwood Ⅲ-Ⅴ acromioclavicular joint dislocation.@*METHODS@#From March 2016 to January 2019, 23 patients with Rockwood Ⅲ-Ⅴ acromioclavicular joint dislocation were treated with modified double Endobutton technique to reconstruct coracoclavicular ligament and Nice node to repair acromioclavicular ligament, including 18 males and 5 females, aged 31 to 53 (43.2±5.4) years, 9 on the left and 14 on the right, and the time from injury to operation was 1 to 10 days. Before operation, X-ray films and CT three-dimensional reconstruction of bilateral shoulder joint were performed. Postoperative complications were observed. Six months after operation, DASHand Constant-Murley scores were used to evaluate the treatment effect.@*RESULTS@#The incision healed in one stage after operation, and no complications such as vascular and nerve injury and stress fracture occurred. All patients were followed up for 6 to 24 (12.0±4.9) months. At 6 months follow-up, the DASH score was 0.40±0.10 lower than that of 19.80±4.50 before operation, and the Constant-Murley score was 94.20±4.20 higher than that of 38.60±3.90 before operation.@*CONCLUSION@#The treatment of Rockwood Ⅲ-Ⅴ dislocation of acromioclavicular joint with double Endobutton technique and nice knot is satisfactory in the early stage. The long-term effect and complications need further follow-up.

OBJECTIVE@#To explore the method and effect of small incision TightRope fixation in the treatment of fresh acromioclavicular joint dislocation.@*METHODS@#From January 2016 to May 2018, 28 cases of fresh acromioclavicular dislocation were treated, including 20 males and 8 females, aged 26 to 87 years with an average age of 51.3 years. The modified Rockwood classification included 1 case of typeⅡ, 22 cases of typeⅢand 4 cases of type V. The average time from injury to operation was 2.4 days. The operative time, shoulder function recovery time and postoperative complications were recorded, and the immediate reduction effect and Karlsson function of shoulder joint were evaluated.@*RESULTS@#In 28 patients, only one Rockwood typeⅡ was used to reconstruct the pyramidal ligament, and the other 27 were used to reconstruct the pyramidal ligament and the trapezoid ligament. The average operation time was (66.50±12.62) min (including intraoperative fluoroscopy time). Twenty-eight cases were followed up for 11 to 20 (16.7±4.6) months. The recovery time of shoulder function was 2 to 7 months with an average of 4 months. During the follow-up period, 1 case had osteolysis and loss of reduction at the clavicular plate site, and the rest had no complications such as re-dislocation and button plate prolapse. Immediate reduction effect after operation:6 cases with reduction insufficiency, 17 cases with complete reduction and 5 cases with excessive reduction;Karlsson function evaluation of shoulder joint in the last follow-up:excellent in 21 cases, good in 6 cases and poor in 1 case;Pearson analysis =0.060, suggesting that the immediate reduction effect of fresh acromioclavicular dislocation operation has no significant correlation with Karlsson function evaluationof shoulder joint in the last follow-up.@*CONCLUSION@#TightRope fixation through a small incision in the base of coracoid process is a simple and effective method for the treatment of dislocation of acromioclavicular joint. There was no significant correlation between the slight difference of immediate reduction effect within 5 mm and Karlsson function evaluation of shoulder joint in the last follow-up. It is suggested to pay attention to the loss of reduction and osteolysis of clavicular plate in clinical follow-up.

OBJECTIVES@#To explore the safety and effectiveness of arthroscopic reconstruction of coracoclavicular ligament by suspensory fixation to manage the acute acromioclavicular joint dislocation.@*METHODS@#From January 2016 to December 2017, 18 cases of acute acromioclavicular joint dislocation were carried out with arthroscopic reconstruction of coracoclavicular ligament by double Endobutton plate suspensory fixation. Anteroposterior view X-ray plain radiographs were obtained on the second day, 6 months and 12 months after the surgery, MRI was performed in 1 year after operation. Meanwhile, subjective and objective scoring were obtained by Vsual Analogue Scale (VAS), Rating Scale of the American Shoulder and Elbow Surgeons (ASES) and University of California at Los Angeles Shoulder Rating Scale (UCLA).@*RESULTS@#All patients were followed up for 12 to 30 months (an average of 18 months). There was no patient with infection, neurovascular injury, loosening and breakage of internal fixation, re-dislocation of acromioclavicular joint, clavicular fracture, coracoid process fracture, etc. Postoperative X-ray showed that all acromioclavicular joints were completely relocated. The follow-up of MRI after 1 year showed no obvious dislocation of acromioclavicular joint and good recovery of acromioclavicular space. Postoperative shoulder joint function, VAS, ASES, UCLA and acromioclavicular distance were significantly improved compared with those before surgery, with statistically significant differences (all <0.05).@*CONCLUSIONS@#Arthroscopic reconstruction of coracoclavicular ligament by suspensory fixation to manage the acute acromioclavicular joint dislocation has the advantages of minimal invasive, rapid functional recovery and less complications and satisfactory early clinical results.

Abstract Objective To evaluate the clinical, radiological and functional results of the surgical treatment of acute acromioclavicular dislocation using a coracoclavicular fixation technique (syndesmopexy) with two metallic anchors, temporary clavicle and scapula fixation, and transfer of the coracoacromial ligament. Methods Longitudinal observational study of 30 patients with diagnoses of acute acromioclavicular dislocation, who were submitted to surgical treatment with a minimum follow-up of six months, and who were evaluated clinically, radiologically, and by the University of California at Los Angeles (UCLA), the Disabilities of the Arm, Shoulder and Hand (DASH) and the Constant-Murley functional scores. Results The mean values of the scores were: UCLA = 32; DASH = 11.21; and Constant-Murley = 86.93, with satisfactory results higher than 80%. The unsatisfactory results were associated with acromioclavicular pain on palpation, positive subacromial impingement tests, and older age group, presenting statistical significance (p < 0.05). Radiologically, higher values on account of the coracoclavicular distance ratio from the operated shoulder compared to the normal shoulder were related to worse outcomes, but with no statistically significant difference. No associations were found between the results of the functional scores and the variables degree of the injury, coracoacromial ligament transfer, clinical impression of loss of reduction and scapulothoracic dyskinesis. Conclusion The technique used provides an efficient fixation, with a high level of satisfaction according to the UCLA, Constant-Murley and DASH scores; moreover, it has a low complication rate, despite the high rate of residual radiological acromioclavicular subluxation.

Resumo Objetivo Avaliar os resultados clínicos, radiológicos, e funcionais do tratamento cirúrgico da luxação acromioclavicular aguda, utilizando a técnica de sindesmopexia coracoclavicular com duas âncoras metálicas, fixação temporária clavículo-escapular, e transferência do ligamento coracoacromial. Métodos Estudo observacional longitudinal com trinta pacientes com diagnóstico de luxação acromioclavicular aguda submetidos à cirurgia, com seguimento mínimo de seis meses, avaliados clínica, radiograficamente, e pelos escores de University of California at Los Angeles (UCLA), Disabilities of the Arm, Shoulder and Hand (DASH) e Constant-Murley. Resultados Os valores médios dos escores foram: UCLA = 32; DASH = 11,21; e Constant-Murley = 86,93, com resultados satisfatórios acima de 80%. Os resultados insatisfatórios foram relacionados à dor acromioclavicular, a testes de impacto subacromial positivos, e aos pacientes de faixa etária mais elevada (p < 0,05). Radiologicamente, valores maiores em razão da distância coracoclavicular do ombro operado, comparado com o ombro normal, foram relacionados a piores resultados, embora sem significância estatística. Não foi observada associação entre os resultados dos escores funcionais e as variáveis grau da lesão, transferência do ligamento coracoacromial, impressão clínica de perda de redução, e discinesia escapulo-torácica. Conclusão A técnica utilizada propicia uma fixação eficiente, com alto índice de satisfação segundo os escores de UCLA, Constant-Murley e DASH. Observou-se baixo índice de complicações apesar da frequência elevada de subluxação acromioclavicular radiológica residual.

Resumen: Introducción: La luxación de la articulación acromioclavicular es una lesión común que se observa principalmente en adultos jóvenes. Las indicaciones para el manejo quirúrgico y la técnica más adecuada siguen siendo controvertidas. Material y métodos: La técnica quirúrgica presentada se basa en una reconstrucción anatómica de los ligamentos coracoclaviculares mediante un injerto autólogo del tendón del semitendinoso, sin túneles en la clavícula y sin ningún dispositivo de fijación, ya que se utilizan sólo suturas. Resultados: Se logró la reconstrucción anatómica y biológica de los ligamentos coracoclaviculares, la cual utilizó un autoinjerto tendinoso sin ningún dispositivo de fijación adicional, lo que minimiza el riesgo de complicaciones relacionadas con el uso de tornillos o implantes metálicos. Discusión: Este procedimiento es un método eficaz y confiable para estabilizar la articulación. Se requieren estudios que informen los resultados funcionales y radiológicos con el empleo de esta técnica quirúrgica para entonces poder asegurar que tiene ventajas sobre otras opciones terapéuticas existentes en la actualidad.

Abstract: Introduction: Dislocation of the acromioclavicular joint is a common injury, which is observed mainly in young adults; indications for surgical management and the most appropriate technique remain controversial. Material and methods: We present a surgical technique, whose objective is the anatomical reconstruction of the coracoclavicular ligaments with autologous semitendinous graft, without tunnels in the collarbone and without fixing devices. Results: This technique is reliable for stabilizing the joint in the short term and we consider that it could neutralize the anteroposterior translation of the distal collarbone. Discussion: Studies are required to report on functional and radiological results, with the use of this surgical technique so that we can then point out that it has advantages over other therapeutic options existing today.

Abstract Objective To evaluate the mechanical properties of sutures commonly used in orthopedic surgeries, characterizing their behavior through tensile tests and determining which one has greater mechanical strength. Method Tensile tests of different sutures were performed in a mechanical testing machine BME 10 kN, using a 50 kgf maximum capacity loading cell. Seven samples from each suture material were tested. Both ends of the sample material were fixed in the proper metal claw, maintaining an initial length of 5 cm. Tests were performed at a speed of 20 mm/minute and at room temperature, recording data for maximum displacement and maximum force at the rupture point. Results FiberWire® #2 (Artrhex, Naples, FL, USA) presented the highest mean strength of rupture (240.17 N), followed by HiFi® #2 (Conmed, Utica, NY, USA) (213.39N) and Ethibond® #5 (Ethicon Inc., Somerville, NJ, USA) (207.38 N). Ethibond® #2 (Ethicon Inc., Somerville, NJ, USA) had the lowestmean strength of rupture (97.8 N). Conclusion Non-absorbable braided polyblend sutures, more recently introduced, are superior to conventional, braided polyester sutures, and FiberWire® #2 is the most resistant suture evaluated in the present study.

Resumo Objetivo Avaliar as propriedades mecânicas dos fios de sutura normalmente usados nas cirurgias ortopédicas e caracterizar seu comportamento por meio de ensaios de tração para verificar qual deles apresenta maior resistência mecânica. Método Os ensaios de tração dos diferentes tipos de fios de sutura foram feitos na máquina de ensaios mecânicos BME 10 kN, comcélula de carga de capacidademáxima de 50 kgf. Foram ensaiadas sete amostras de cada tipo de fio de sutura, foram fixadas cada uma das extremidades da amostra na garra metálica própria para o ensaio de fios e manteve-se o comprimento inicial de 5 cm. Os ensaios foram feitos com uma velocidade de 20 mm/minuto e à temperatura ambiente, registraram-se os dados de força máxima e o deslocamento máximo na ruptura dos fios. Resultados A força média de rupturamais elevada foi observada na sutura FiberWire® 2 (Artrhex, Naples, FL, EUA) (240,17 N), seguida pela HiFi® 2 (Conmed, Utica, NY, EUA) (213,39 N) e Ethibond® 5 (Ethicon Inc., Somerville, NJ, EUA) (207,38 N). A menor força média de ruptura foi obtida para o fio Ethibond® 2 (Ethicon Inc., Somerville, NJ, EUA) (97,8 N). Conclusão Os fios de sutura não absorvíveis de polimistura trançada, de surgimento mais recente, são superiores ao fio de sutura convencional de poliéster trançado. O FiberWire® 2 é o mais resistente dos fios avaliados no presente estudo.
