ABSTRACT

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

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

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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

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.

ABSTRACT

Resumen: Introducción: En la luxación acromioclavicular inestable verticalmente es elemental el tratamiento quirúrgico mediante la reconstrucción de los ligamentos coracoclaviculares, con la finalidad de recuperar su estabilidad y función normal. Existen técnicas de un solo túnel o de dos en la clavícula (anatómica) con material biológico o sintético. Material y métodos: Es un estudio cuasiexperimental prospectivo longitudinal; se incluyeron 33 pacientes entre 20 y 50 años de edad con diagnóstico de luxación acromioclavicular completa con inestabilidad vertical. Se les efectuó plastía sólo de los ligamentos coracoclaviculares con técnica anatómica de Mazzocca usando injerto tendinoso autólogo del peroneo lateral corto. La evaluación de resultados fue con el test de PENN. Resultados: 100% de los pacientes se encuentran sin dolor y con un arco de movilidad normal del hombro un año después de la cirugía. Radiográficamente, la distancia coracoclavicular comparada con el lado sano tuvo una diferencia promedio de 1.0 mm en reposo y 0.9 mm bajo carga. Discusión: La plastía tendinosa de los ligamentos coracoclaviculares con técnica anatómica mediante injerto tendinoso autólogo del peroneo lateral corto permite recuperar la estabilidad acromioclavicular y la función normal del hombro a 12 meses de seguimiento.


Abstract: Introduction: In the dislocation acromioclavicular unstable vertically, the surgical treatment is elementary by the plasty of the ligaments coracoclaviculares, with the purpose of recovering its stability and normal function. There are techniques of a single tunnel in the clavicle or two tunnels (anatomical), with biological or synthetic material. Material and methods: It is a longitudinal prospective experimental study; we included 33 patients between 20 and 50 years of age with diagnosis of complete acromioclavicular dislocation with vertical instability. Reconstruction was performed only of the coracoclavicular ligaments with Mazzoca's technique of using autologous tendon graft of the short lateral peroneus. The evaluation of results was with the PENN test. Results: 100% of patients are painless and with an arch of normal shoulder mobility one year after surgery. Radiographically, the coracoclavicular distance compared to the healthy side had an average difference of 1.0 mm at rest and 0.9 mm under load. Discussion: The reconstruction of the coracoclavicular ligaments with anatomical technique by autologous tendon graft of the short lateral peroneus, allows to recover the acromioclavicular stability and the normal function of the shoulder.

ABSTRACT

ABSTRACT OBJECTIVE: The posterosuperior shoulder access used in surgical treatment for acromioclavicular dislocation was constructed through dissection of 20 shoulders from 10 recently chilled adult cadavers, and the distances from this route to the nearby neurovascular structures were analyzed. METHODS: A Kirschner wire was introduced into the top of the base of the coracoid process through the posterosuperior shoulder access, in the area of the origin of the conoid and trapezoid ligaments, thus reproducing the path for inserting two anchors for anatomical reconstruction of the coracoclavicular ligaments. The smallest distance from the insertion point of the Kirschner wire to the suprascapular nerve and artery/vein was measured. RESULTS: The mean distance from the suprascapular nerve to the origin of the coracoclavicular ligaments at the top of the base of the coracoid process was 18.10 mm (range: 13.77-22.80) in the right shoulder and 18.19 mm (range: 12.59-23.75) in the left shoulder. The mean distance from the suprascapular artery/vein to the origin of the coracoclavicular ligaments was 13.10 mm (range: 9.28-15.44) in the right shoulder and 14.11 mm (range: 8.83-18.89) in the left shoulder. Comparison between the contralateral sides did not show any statistical difference. CONCLUSION: The posterosuperior shoulder access route for anatomical reconstruction of the coracoclavicular ligaments in treating acromioclavicular dislocation should be performed respecting the minimum limit of 8.83 mm medially.


RESUMO OBJETIVO: Os autores fizeram o acesso posterossuperior do ombro usado no tratamento cirúrgico da luxação acromioclavicular, a partir da dissecção de 20 ombros de 10 cadáveres adultos recém-resfriados, e analisaram as distâncias da via às estruturas neurovasculares próximas. MÉTODOS: Introduziu-se um fio de Kirschner no topo da base do processo coracoide pelo acesso posterossuperior do ombro, na área de origem dos ligamentos conoide e trapezoide, para reproduzir o trajeto da inserção de duas âncoras para reconstrução anatômica dos ligamentos coracoclaviculares. Mediu-se a menor distância do ponto de inserção do fio de Kirschner ao nervo e à artéria/veia supraescapular. RESULTADOS: A média da distância do nervo supraescapular até a origem dos ligamentos coracoclaviculares no topo da base do processo coracoide foi de 18,10 mm (13,77 a 22,80) no ombro direito e 18,19 mm (12,59 a 23,75) no ombro esquerdo. A média da distância da artéria/veia supraescapular até a origem dos ligamentos coracoclaviculares foi de 13,10 mm (09,28 a 15,44) no ombro direito e 14,11 mm (08,83 a 18,89) no ombro esquerdo. Não houve diferença estatística comparativa entre os lados contralaterais. CONCLUSÃO: A via de acesso posterossuperior do ombro para reconstrução anatômica dos ligamentos coracoclaviculares no tratamento das luxações acromioclaviculares deve ser feita com respeito ao limite de 08,83 mm medialmente.

ABSTRACT

Introducción: La elección del tratamiento quirúrgico de la luxación acromioclavicular, es aún motivo de controversia. En este trabajo se describe una técnica combinada: realizamos un primer tiempo artroscópico, y un segundo tiempo con abordaje mini invasivo. Material y Métodos: Se intervinieron 41 pacientes con luxación acromioclavicular grados III, IV y V. Para el seguimiento Se incluyeron luxaciones agudas, crónicas y cirugías de revisión; se excluyeron pacientes con otras patologías de hombro asociadas, obteniendo un total de 24 pacientes en el seguimiento final. Con una edad promedio de 28,6 años, 20 siendo del sexo masculino. Los pacientes fueron evaluados con el Score de Ucla, el Score de Constant, la evaluación del dolor mediante la Escala Visual Analógica (VAS) preoperatorio, a los 6 y 12 meses Postoperatorio. Resultados: Obtuvimos un Score de Constant preoperatorio de 41,3;: 89.4 a los 6 meses; 92.3 al año. El Score de UCLA, respectivamente: 21.7; 29.1; 31.4 Preoperatorio, a los 6 y 12 meses respectivamente. VAS: 8,4; 2,3; 1,2. Hubo 2 casos de reruptura por trauma y un caso de insatisfacción estética de la cicatriz. Conclusión: Esta técnica brinda una reconstrucción anatómica sólida, estable en plano coronal y axial, combinando dos métodos de reducción, uno sintético y otro biológico, donde el primero aporta la resistencia adecuada hasta la revascularización e integración del aloinjerto, con muy buenos resultados a mediano plazo. Tipo de estudio: Serie de casos. Nivel de evidencia: IV.


Introduction: The optimal surgical technique of AC jont dislocations is still controversial. This paper describes a combined reconstructive technique wich involves a first arthroscopic step, and a second one with minimally invasive approach. Meterials and methods: We performed 41 interventions in patients with acromioclavicular dislocation grade III, IV and V. Acute and chronic dislocations and revision surgeries were included. We excluded patients with other associated pathologies that may cause shoulder pain or function limitation, leaving 24 cases for the final sample. The average age was 28.6 years. 20 patients were male. We use UCLA, VAS and Constant scores before the procedure, and in the postoperative period at 6 and 12 months. Results: The scores achieved the following results: Constant preoperative 41.3; 6 months: 89.4; and 12 months: 92.3. UCLA, respectively: 21.7; 29.1; 31.4. VAS: 8,4; 2,3; 1,2. A case of an esthetic dissatisfaction and two traumatic ruptures were reported. Conclusions: This technique provides a solid, stable and anatomical reconstruction in both axial and coronal planes. It involves two reduction methods, synthetic and biological, where the first one provides adequate strength until allograft revascularization and integration occurs, with goods results in the medium term. Type of Study: Case series. Level of evidence: IV.

ABSTRACT

Valorar los resultados de la técnica quirúrgica asistida por artroscopía indicada para el tratamiento de la inestabilidad acromioclavicular crónica (IAC), basada en la fijación coracoclavicular (CC) no-rígida más reconstrucción CC anatómica con aloinjerto tendinoso. Se incluyó a los pacientes con IAC intervenidos entre 2008 y 2012. Las valoraciones clínicas se realizaron mediante el SF36, la EVA y el DASH, aplicados en la visita previa (VPI) a la intervención y en la última visita de seguimiento (UVS). El Constant score y la Escala de Satisfacción General (0-10) se aplicaron en la última visita de seguimiento. Se valoró el desarrollo de subluxaciones secundarias. Se incluyeron 10 pacientes. Edad media 41 años [rango 33-55]. Seguimiento medio 25.50 meses [rango 24-30].En todos los pacientes el tratamiento quirúrgico se indicó cuando el tratamiento conservador fracasó. Cuestionarios aplicados en la VPI y en la UVS: 1. SF36 físico: VPI 29.60 ± 3.41 y UVS 59.58 ± 1.98 (p = 0.000); 2. SF36 mental: VPI 46.57 ± 3.80 y UVS 56.62 ± 1.89 (p = 0.000); 3. EVA: VPI 5.17 ± 2.40 y UVS 1.67 ± 2.07 (p = 0.022); y 4. DASH: VPI 63.33 ± 23.56 y UVS 2.61 ± 1.79 (p = 0.000). El Constant score y la satisfacción general de la UVS fueron 95.56 ± 3.28 y 9.22 ± 0.67 respectivamente. No hubo subluxaciones secundarias. El tratamiento de la IAC mediante un dispositivo de suspensión CC y una reconstrucción anatómica de los ligamentos CC asistida por artroscopía, puede ofrecer una mejoría significativa de la calidad de vida de los pacientes y representa una estrategia que al contemplar una fijación CC mecánica primaria, puede minimizar las posibilidades de fracaso y desarrollo de subluxaciones secundarias.


The purpose of this paper is to assess the results obtained with the arthroscopy-assisted surgical technique for the treatment of chronic acromioclavicular joint instability (CACJI), based on non-rigid coracoclavicular (CC) fixation and anatomical CC reconstruction with a tendinous allograft. Patients with CACJI who underwent surgery between 2008 and 2012 were included in the study. Clinical assessments included SF36, VAS and DASH, applied at the preoperative visit (POV) and at the last follow-up visit (LFUV). The Constant score and the General Satisfaction Score (0-10) were applied at the last follow-up visit. Occurrence of secondary subluxations was assessed. Ten patients were included; mean age was 41 years (range 33-55). Mean follow-up was 25.50 months (range 24-30). Surgical treatment was indicated in all patients after failure of conservative treatment. Questionnaires applied at the POV and the LFUV showed the following results: 1. SF36: physical, POV = 29.60 ± 3.41 and LFUV = 59.58 ± 1.98 (p = 0.000); 2. SF36 mental, POV = 46.57 ± 3.80 and LFUV = 56.62 ± 1.89 (p = 0.000); 3. VAS: POV = 5.17 ± 2.40 and LFUV: 1.67 ± 2.07 (p = 0.022); and 4. DASH: POV = 63.33 ± 23.56 and LFUV = 2.61 ± 1.79 (p = 0.000). The Constant score and the general satisfaction at the LFUV were 95.56 ± 3.28 and 9.22 ± 0.67, respectively. There were no secondary subluxations. Treatment of CACJI with a CC suspension device and arthroscopically-assisted anatomical reconstruction of CC ligaments may provide a significant quality of life improvement to patients. It is a strategy that, upon considering primary mechanical CC fixation, may minimize the chance of failure and occurrence of secondary subluxations.

To compare quality of life in patients with Tossy type III acromioclavicular dislocation treated with the hook-plate ORIF technique, the Weaver & Dunn technique and the Bosworth technique. Material and methods: A cross-sectional analytical survey was conducted from January 2012 to April 2013 in patients with a diagnosis of Tossy type III acromioclavicular dislocation treated surgically with the hook-plate ORIF technique, the Weaver & Dunn technique, and the Bosworth technique. We included patients ages 18 to 70 years old, operated within three weeks after the diagnosis. Quality of life was assessed using the hetero-administered DASH questionnaire once the informed consent was obtained. Results: Forty-seven patients were operated on. They were divided into 3 groups: hook-plate ORIF technique, with 26 patients: Weaver & Dunn technique, 11 patients; and Bosworth technique, 10 patients. Sex and age distribution were similar in all 3 groups, with p = 0.137 and p = 0.252, respectively. Time elapsed after surgery was similar in all 3 groups, with p = 0.051. The hook-plate ORIF technique was the most frequently used one, in 26 surgeries. 96.4% of patients had mild disability and symptoms with the hook-plate ORIF technique, and 100% with the Bosworth and Weaver & Dunn techniques. Conclusions: Quality of life was similar with all 3 surgical techniques and involved mild disability and symptoms. The hook-plate ORIF technique was the most frequently used technique.

ABSTRACT

OBJETIVO: Avaliar os resultados do tratamento cirúrgico de 84 luxações acromioclaviculares agudas com a utilização da via de acesso posterossuperior do ombro. MÉTODOS: Foram avaliados 84 casos de luxações acromioclaviculares agudas grau III da classificação de Allman-Tossy operados de novembro de 2002 a maio de 2010. A média de idade dos pacientes foi de 34 anos. O diagnóstico foi realizado por avaliação clínica e radiográfica. Os pacientes foram operados pela mesma equipe cirúrgica em até três semanas da data do trauma realizando-se a via de acesso posterossuperior do ombro com acesso ao topo da base do processo coracoide para colocação de duas âncoras utilizadas na redução da luxação. O seguimento mínimo foi de 12 meses. A avaliação clínica-radiográfica pós-operatória foi realizada pelos critérios de Karlsson modificados e do escore da Universidade da Califórnia em Los Angeles (UCLA). RESULTADOS: Dos 84 pacientes operados, 92,8% apresentavam resultados bons ou excelentes e 7,2% de resultados regulares ou fracos pelo escore de avaliação da UCLA. Pelos critérios de Karlsson modificados 76,2% foram avaliados como grau A, 17,9% como grau B e 5,9% como grau C. CONCLUSÃO: A VIA de acesso posterossuperior do ombro é uma nova opção para acesso ao processo coracoide e tratamento das luxações acromioclaviculares, com resultados clínicos e radiográficos equivalentes aos da literatura.


OBJECTIVE: To evaluate the results from surgical treatment of 84 cases of acute acromioclavicular dislocation, using a posterosuperior access route. METHODS: Eighty-four cases of acute acromioclavicular dislocation (grade III in the Allman-Tossy classification) operated between November 2002 and May 2010 were evaluated. The patients' mean age was 34 years. The diagnoses were made using clinical and radiographic evaluations. The patients were operated by the same surgical team, within three weeks of the date of the trauma, using a posterosuperior approach to the shoulder to access the top of the base of the coracoid process for placement of two anchors, which were used in reducing the dislocation. The minimum follow-up was 12 months. The postoperative clinical-radiographic evaluation was done using the modified Karlsson criteria and the University of California at Los Angeles (UCLA) score. RESULTS: 92.8% of the 84 patients treated presented good or excellent results, and 7.2% presented fair or poor results, using the UCLA assessment score. According to the modified Karlsson criteria, 76.2% were assessed as grade A, 17.9% as grade B and 5.9% as grade C. CONCLUSION: The posterosuperior access route to the shoulder is a new option for accessing the coracoid process and treating acromioclavicular dislocation, with clinical and radiographic results equivalent to those in the literature.

ABSTRACT

Ocorrendo isoladamente, as fraturas da clavícula e as luxações acromioclaviculares são lesões muito comuns. A combinação de uma luxação acromioclavicular e de uma fratura do terço lateral da clavícula não é rara. Entretanto, existem muito poucos casos descritos de luxações acromioclaviculares associadas a fraturas do terço médio da clavícula; aquelas associadas a fraturas do terço medial são ainda mais raras. Nós reportamos o caso de um indivíduo adulto do sexo masculino que sofreu uma luxação acromioclavicular (tipo IV) associada a uma fratura extra-articular desviada da extremidade medial da clavícula (grupo 3 de Almann) em um acidente ciclístico. O paciente foi tratado na fase aguda com redução aberta e fixação interna das duas lesões. Na avaliação clínica, 12 meses após a cirurgia, o paciente apresentava-se assintomático, com mobilidade ativa e passiva completa, força e resistência normais e simetria das cinturas escapulares. As radiografias e a tomografia computadorizada tridimensional mostravam subluxação posterossuperior persistente da articulação acromioclavicular e consolidação anatômica da fratura clavicular.


Fractures of the clavicle and acromioclavicular dislocations are very common injuries when they occur separately. The combination of an acromioclavicular dislocation and a fracture of the lateral third of the clavicle is not rare. However, there are very few reported cases of acromioclavicular dislocations associated with fractures of the middle third of the clavicle; those associated with fractures of the medial third are even rarer. We report the case of an adult male who suffered an acromioclavicular dislocation (type IV) associated with a displaced extra-articular fracture of the medial end of the clavicle (Almann group 3) in a cycling accident. The patient was treated during the acute phase with open reduction and internal fixation of the two lesions. At the clinical evaluation 12 months after the surgery, the patient was asymptomatic, with full active and passive mobility, and normal strength and endurance of the shoulder girdle. Radiographs and a three-dimensional CT scan showed persistent posterosuperior subluxation of the acromioclavicular joint and anatomical consolidation of the clavicular fracture.

ABSTRACT

Introducción: La luxación acromioclavicular es una lesión traumática del hombro. Las alternativas quirúrgicas incluyen el uso de tornillos, suturas o anclajes. El uso de suturas tipo Fiber- Tape™ es una alternativa usada frecuentemente, sin tener actualmente un consenso sobre las variables que influyen en la resistencia de la reparación. Objetivo: Evaluar el punto máximo de fallo (PMF) de distintas distancias entre los nudos de suturas FiberTape™. Hipótesis: Una mayor distancia entre las suturas aumenta la resistencia. Material y Método: Modelo mecánico porcino ex vivo. Tres grupos de 12 muestras (N=36). Grupo 1: distancia 5 mm, Grupo 2: distancia 10 mm, Grupo 3: distancia 15 mm. Se realiza una tracción axial continua y progresiva, hasta el fallo. Resultados: Grupo 1: 312N (182-442N), Grupo 2: 430N (368-595N), Grupo 3: 595,5N (441-978N) (p≤0,05). Conclusión: La distancia de 15 mm entre los nudos presenta una resistencia superior, estadísticamente significativa respecto al resto.


Introduction: Acromioclavicular dislocation is a traumatic injury of the shoulder. The surgical options include the use of screws, sutures or anchors. The use of sutures type FiberTape™ is a frequently used alternative, having no current consensus on the variables that influence the strength of the repair. Objective: Evaluate ultimate failure point (UFP) of differents distances between the knots of Fibertape™ suture. Hypothesis: A greater distance between sutures improves resistance. Material and Method: Porcine metatarsal samples- Three groups of 12 samples (N=36). Group 1: 5 mm of distance, Group 2: 10 mm of distance, Group 3: 15 mm of distance. A continuous axial traction until failure was applied. Results: Group 1: 312N (182-442N), Group 2: 430N (368-595N), Group 3: 595,5N (441-978N) (p<0.05). Conclusion: The distance of 15 mm between the nodes has a higher resistence, statistically significant compared to the rest.
