RESUMEN

INTRODUCTION AND OBJECTIVES: Tendon xanthomas (TX) are lipid deposits highly specific to familial hypercholesterolemia (FH). However, there is significant variability in their presentation among FH patients, primarily due to largely unknown causes. Lipoprotein(a) is a well-established independent risk factor for atherosclerotic cardiovascular disease in the general population as well as in FH. Given the wide variability of lipoprotein(a) among FH individuals and the likelihood that TX may result from a proatherogenic and proinflammatory condition, the objective of this study was to analyze the size of TX in the Achilles tendons of FH participants and the variables associated with their presence, including lipoprotein(a) concentration. METHODS: A cross-sectional study was conducted on 377 participants with a molecular diagnosis of heterozygous FH. Achilles tendon maximum thickness (ATMT) was measured using ultrasonography with standardized equipment and procedures. Demographic variables and lipid profiles were collected. A multivariate linear regression model using a log-Gaussian approach was used to predict TX size. Classical cardiovascular risk factors and lipoprotein(a) were included as explanatory variables. RESULTS: The mean low-density lipoprotein cholesterol level was 277mg/dL without lipid-lowering treatment, and the median ATMT was 5.50mm. We demonstrated that age, sex, low-density lipoprotein cholesterol, and lipoprotein(a) were independently associated with ATMT. However, these 4 variables did not account for most the interindividual variability observed (R2=0.205). CONCLUSIONS: TX, a characteristic hallmark of FH, exhibit heterogeneity in their presentation. Interindividual variability can partially be explained by age, male sex, low-density lipoprotein cholesterol, and lipoprotein(a) but these factors account for only 20% of this heterogeneity.

RESUMEN

La deformidad en equino del tobillo ocurre como consecuencia de múltiples entidades. Aunque la primera línea de tratamiento es la conservadora, las modalidades quirúrgicas son necesarias en la mayoría de los enfermos pediátricos. Estas últimas son las más empleadas por zonas del complejo músculo-tendinoso, en especial los alargamientos fraccionados y en forma de Z-plastia. El objetivo de este trabajo es actualizar y brindar información sobre los distintos procedimientos quirúrgicos en la corrección de la deformidad en equino del tobillo. En la búsqueda y análisis de la información se emplearon las siguientes palabras: equinus deformity, equino varus, equino valgus; drop foot deformity y Achilles tendon Z-lengthening. A partir de la información obtenida, se realizó unala revisión bibliográfica de un total de 187 artículos publicados en las bases de datos PubMed, Hinari, SciELO, EBSCO, Scopus, Medscape y Medline, mediante el gestor de búsqueda y administrador de referencias EndNote. De ellos se utilizaron 30, 28 de los últimos cinco años. Se hace referencia a la anatomía esencial de la zona, al igual que a la prueba de Silfverskiöld. Con relación a la imagenología, se describe la técnica para calcular la distancia del tendón a alargar. Se mencionan las técnicas quirúrgicas de alargamiento fraccionado, por Z-plastia, trasposición anterior del tendón de Aquiles y la hemiepifisiodesis.

Equinus deformity of the ankle occurs as a consequence of multiple entities. Although the first line of treatment is conservative, surgical modalities are necessary in most pediatric patients. The latter are the most used for areas of the muscle-tendinous complex, especially fractional and Z-plasty-shaped lengthening. The aim of this work is to update and provide information on the different surgical procedures in the correction of equinus deformity of the ankle. In the search and analysis of the information, the following words were used: equinus deformity, equinovarus, equinovalgus; drop foot deformity and Achilles tendon Z-lengthening. Based on the information obtained, a bibliographic review of a total of 187 articles published in PubMed, Hinari, SciELO, EBSCO, Scopus, Medscape and Medline databases was carried out using the search manager and reference administrator EndNote. Of these, 30 were used, 28 of the last five years. Reference is made to the essential anatomy of the area, as well as to the Silfverskiöld test. In relation to imaging, the technique to calculate the distance of the tendon to be lengthened is described. Fractional lengthening surgical techniques are mentioned, by Z-plasty, anterior transposition of the Achilles tendon and hemiepiphysiodesis.

Se deben tener consideraciones especiales cuando se realizan reparaciones quirúrgicas del tendón de Aquiles. Su anatomía e irrigación particular plantean desafíos únicos para el manejo, y tener comprensión profunda de estas características es crucial para escoger el tratamiento adecuado y lograr resultados exitosos. El objetivo de este trabajo es analizar la eficiencia de la reparación quirúrgica de la rotura aguda del tendón de Aquiles con técnica de Dresden, entre el 2015 y el 2021. Se realizó un estudio de tipo analítico, observacional, longitudinal y prospectiva. El análisis del aspecto estadístico fue a través de estadística descriptiva y asociación de las variables. Se incluyeron 34 pacientes con un promedio de 42 años, la mayoría de sexo masculino. Al aplicar las escalas VISA-A se obtuvo un promedio de 12 puntos, 67,5 puntos a los 6 meses y 80,5 puntos a los 12 meses. En la encuesta SF-12 a los 6 meses se obtuvo un promedio de 68,5 puntos y 80 puntos a los 12 meses; un paciente presentó rechazo de la sutura y 6 afirmaron algún grado de edema residual aun al año de la cirugía. La reparación quirúrgica con técnica de Dresden mejora la funcionabilidad del tendón de malos resultados a regulares y buenos resultados al año de seguimiento. El 68% de la población estudiada afirmó que se encuentran satisfechos con la cirugía(AU)

Special considerations must be made when performing surgical repairs of the Achilles tendon. Its particular anatomy and blood supply pose unique management challenges, and a thorough understanding of these characteristics is crucial to choosing the right treatment and achieving successful results. The objective of this work is to analyze the efficiency of the surgical repair of the acute rupture of the Achilles tendon with the Dresden technique, between 2015 and 2021. An analytical, observational, longitudinal and prospective study was carried out. The analysis of the statistical aspect was through descriptive statistics and association of the variables. 34 patients with an average age of 42 years were included, most of them male. When applying the VISA-A scales, an average of 12 points was obtained, 67,5 points at 6 months and 80,5 points at 12 months. In the SF-12 survey at 6 months an average of 68,5 points and 80 points at 12 months were obtained; One patient presented rejection of the suture and 6 reported some degree of residual edema even one year after surgery. Surgical repair with the Dresden technique improves the functionality of the tendon from poor to regular results and good results after a year of follow-up. 68% of the population studied stated that they are satisfied with the surgery(AU)

RESUMEN

Objective: The purpose of this study is to evaluate the clinical outcomes and complications of percutaneous achilles tendon repair with absorbable sutures. Material and methods: A prospective cohort study including patients treated for an achilles tendon rupture from January 2016 to March 2019 was conducted. Inclusion criteria: ≥18 years of age, non-insertional (2–8cm proximal to insertion) achilles tendon ruptures. Open or partial ruptures were excluded. The diagnosis was based on clinical criteria and confirmed by ultrasonography in all patients. Epidemiological data, rupture and healing risk factors, previous diagnosis of tendinopathy, pre-rupture sport activity, job information, mechanism of rupture and the time in days between lesion and surgery were collected. Patients were assessed using visual analogue scale (VAS) at the 1, 3, 6 and 12-month follow-up. The achilles tendon rupture score (ATRS) were assessed at the 6 and 12 month follow-up. Ultrasound was performed at the 6-month follow-up. The re-rupture rate and postoperative complications were also collected. Conclusions: In our experience, percutaneous achilles tendon repair with absorbable sutures in patients with an acute achilles tendon rupture has shown good functional results but with a high incidence of complications. Although most complications were transitory sural nerve symptoms, this complication would be avoided in patients treated conservatively. For this reason, conservative treatment associated with an early weightbearing rehabilitation protocol should be considered a viable option for patients with achilles tendon ruptures, mainly in cooperative young patients.(AU)

Objetivo: El propósito de este estudio es evaluar los resultados clínicos y las complicaciones de la reparación percutánea del tendón de Aquiles con suturas reabsorbibles. Material y métodos: Se realizó un estudio de cohorte prospectivo que incluye pacientes tratados por una rotura del tendón de Aquiles desde enero de 2016 hasta marzo de 2019. Criterios de inclusión: ≥18años de edad, roturas del tendón de Aquiles no insercionales (de 2 a 8cm proximales a la inserción). Se excluyeron roturas abiertas o parciales. El diagnóstico se basó en criterios clínicos y se confirmó mediante ecografía en todos los pacientes. Se recogieron datos epidemiológicos, factores de riesgo de rotura y cicatrización, diagnóstico previo de tendinopatía, actividad deportiva previa a la rotura, información laboral, mecanismo de rotura y tiempo en días entre la lesión y la cirugía. Los pacientes fueron evaluados utilizando la escala analógica visual (VAS) en el seguimiento de 1, 3, 6 y 12meses. La puntuación de rotura del tendón de Aquiles (ATRS) se evaluó a los 6 y 12meses de seguimiento. La ecografía se realizó a los 6meses de seguimiento. También se recogieron la tasa de re-ruptura y las complicaciones postoperatorias. Conclusiones: En nuestra experiencia, la reparación percutánea del tendón de Aquiles con suturas reabsorbibles en pacientes con rotura aguda del tendón de Aquiles ha mostrado buenos resultados funcionales pero con una alta incidencia de complicaciones. Aunque la mayoría de las complicaciones fueron síntomas transitorios del nervio sural, esta complicación se evitaría en pacientes tratados de forma conservadora. Por esta razón, el tratamiento conservador asociado a un protocolo de rehabilitación con carga temprana debe considerarse una opción viable para pacientes con roturas del tendón de Aquiles, principalmente en pacientes jóvenes colaboradores.(AU)

Inclusion criteria: ≥18 years of age, non-insertional Achilles tendon ruptures. Diagnosis based on clinical criteria, confirmed by ultrasonography. Assessment using Visual Analogue Scale (VAS), Achilles Tendon Rupture Score (ATRS) and ultrasound. Re-rupture rate and postoperative complications were collected. Results: VAS scoring (SD) at 1, 3, 6 and 12 months follow-up (FU) were 2.63 (0.83), 1.79 (1.25), 0.69 (1.09) and 0.08 (0.39), respectively. Mean (SD) ATRS score was 92.45 points at 6 months (6.27) and 94.04 points at 12 months FU (4.59). Three re-ruptures (5.77%) occurred with a mean time between surgery and re-rupture of 108.75 days (SD 28.4), all of them within 4-month FU. No ruptures at the time to return to sports activity. Thirteen complications (25%) (3 re-ruptures, 1 superficial wound infection and 9 transitory sural nerve injuries). Conclusions: Percutaneous Achilles tendon repair with absorbable sutures in patients with acute Achilles tendon ruptures has shown good functional results but with a high incidence of complications. Although most complications were transitory sural nerve symptoms, these would be avoided with conservative treatment.

RESUMEN

Introducción: Las fluoroquinolonas han sido asociadas con aumento del riesgo de tendinopatía y rotura del tendón de Aquiles (RTA), especialmente en pacientes mayores de 60 años. Métodos: Se llevó a cabo un estudio retrospectivo en el que se incluyó a los pacientes mayores de 60 años con RTA atendidos en nuestro centro durante el período 2000-2017. Resultados: Se identificó a 44 pacientes con RTA, de los cuales 18% (8/44) habían sido tratados previamente con fluoroquinolonas, con una media de edad al diagnóstico de RTA de 77,37 años y corticoterapia concomitante en 4 de ellos. En 7 pacientes la rotura fue espontánea y todas requirieron tratamiento quirúrgico. Se encontró una frecuencia significativamente mayor de tabaquismo, corticoterapia concomitante y roturas espontáneas en el grupo tratado con fluoroquinolonas. Conclusiones: La RTA es un evento adverso que puede ocurrir en pacientes mayores de 60 años tratados con fluoroquinolonas, por lo que debería realizarse una adecuada evaluación relación riesgo-beneficio en esta población, especialmente en presencia de factores de riesgo asociados.(AU)

Background: Fluoroquinolones have been associated with increased risk of tendinopathy and Achilles tendon rupture (ATR), especially in patients over 60 years of age.Methods: A retrospective study was carried out including patients over 60 years of age with ATR attended in our centre over the period 2000-2017. Results: We identified 44 patients with RTA, of whom 18% (8/44) had been previously treated with fluoroquinolones, with a mean age at diagnosis of ATR of 77.37 years and concomitant corticotherapy in 4 of them. In 7patients, the rupture was spontaneous and all required surgical management. A significantly higher frequency of smoking, concomitant corticotherapy and spontaneous ruptures were found in the group treated with fluoroquinolones. Conclusions: ATR is an adverse event that can occur in patients over 60 years of age treated with fluoroquinolones, so an adequate risk-benefit assessment should be carried out in this population, especially in the presence of associated risk factors.(AU)

RESUMEN

BACKGROUND AND OBJECTIVES: Insertional tendinopathy accounts for 23% of the pathology of the Achilles tendon. Surgery is indicated when conservative treatment of pain and functional limitation fails. Our objective is to analyse the clinical-functional results of surgical treatment with disinsertion, debridement and double row reattachment with high strength suture tape. MATERIAL AND METHODS: We present 13 patients with insertional Achilles tendinopathy, treated between February 2015 and October 2016. In all of them we performed inverted T-tendon disinsertion, debridement and calcareoplasty followed by double row tendon re-anchorage, without knots, with high resistance suture tape. Functional results were assessed with the AOFAS scale before and after surgery, with an average follow-up of 22 months. RESULTS: The patients, 11 males and 2 females, with an average age of 43 years, presented a preoperative AOFAS score of 34.77±10.1 that reached 90.85±7 points after the operation, with an average increase of 56.08 points (IC 95% 48.13-64.02; P<0.01). The time to return to sports activities was 19 weeks (16-22). There were no complications. CONCLUSION: The technique we present reports excellent results as a surgical treatment of insertional Achilles tendinopathy with intralesional calcification; it allows a wide contact surface between bone and tendon and an earlier return to previous sports activity.

RESUMEN

The Achilles tendon acts by transmitting the force created by the contraction of the sural triceps to the calcaneus. This allows the elevation during the gait cycle. A sudden contraction in elderly patients may generate avulsion fracture of the posterior tubercle of the calcaneus due to poor bone quality or rupture of the tendon, with one of these two structures yielding in most cases. We report the case of a 72-year-old woman who suffered a low energy right heel trauma while stepping off the bus. She was diagnosed an avulsion fracture of the posterior tubercle of the calcaneus. When performing ORIF procedure of the fracture, an associated rupture of the Achilles tendon is diagnosed. Both pathologies are treated in the same surgical act. We recommend using a second imaging study along with the x-ray in order to anticipate associated injuries and adequate surgical planning in elderly patients.

RESULTADOS A los 5 años de la cirugía del pie izquierdo y 4 años del pie derecho la paciente estaba asintomática. Presentaba una fuerza para la flexión plantar bilateral de 5/5, pudiendo caminar y subir escaleras sin molestias. Presentaba una escala AOFAS de 85 y 90 puntos en el pie izquierdo y derecho, respectivamente. No hubo recidivas. DISCUSIÓN Los xantomas son depósitos de colesterol en el tejido conectivo de la piel, tendones o fascia, como resultado de una hiperlipoproteinemia. La importancia del caso radica en su sospecha diagnóstica, ya que la xantomatosis cerebrotendinosa suele manifestarse en pacientes de menos de 30 años de edad y en los que se ha recomendado la resección radical de las tumoraciones, e incluso del tendón, debido a las frecuentes recidivas. CONCLUSIÓN En pacientes de mayor edad con lesiones que infiltran el tendón, se puede optar por un tratamiento menos agresivo con un buen resultado clínico.

OBJETIVE Presentation of an unusual case of cerebrotendinous xanthomatosis in an elderly patient whose first manifestation was bilateral Achilles tendon xanthomas. MATERIAL AND METHODS 62-year-old woman presenting solid and polylobed tumors on the posterior aspect of both Achilles tendons for eight years. The diagnosis was made by means of hyperlipidemia and a genetic study. Surgical partial excision of the tumors was performed. RESULTS Five years after surgery on the left foot and four years after the right foot, the patient was asymptomatic. Bilateral plantar flexion force was 5/5, The patient was able to walk and climb stairs without discomfort. AOFAS score was 85 and 90 on the left and right feet, respectively. There were no recurrences. DISCUSSION Xanthomatosis is a genetic alteration with deposits of cholesterol in connective tissue of the skin, tendons or fascia, because of hyperlipoproteinemia. The importance of the present case lies in its diagnostic suspicion, since cerebrotendinous xanthomatosis manifests usually in patients under 30 years of age and in whom radical resection of tumors, and even of the tendon, has been recommended due to frequent recurrences . CONCLUSION In older patients with tumors that infiltrate the tendon, a less aggressive treatment can be chosen with a good clinical result.

RESUMEN

The treatment of a chronic rupture of the Achilles tendon remains difficult. Different techniques such as augmentation or plasties are used for restoring the gap in these ruptures. The combination of Achilles tendon rupture with other tendon ruptures may increase the difficulty in their treatment. We present a rare combination of a delayed Achilles tendon rupture and a peroneus brevis tendon rupture and its management. The importance of the presented case is the combination of both ruptures that adds difficulty to the surgical technique. A thorough analysis should be made of the magnetic resonance findings when planning a tendon transposition. To our knowledge, there are no reports of a simultaneous combination of an Achilles tendon rupture and a peroneus brevis tendon rupture.

RESUMEN

Introducción: Las roturas del tendón de Aquiles son lesiones traumáticas frecuentes. El tratamiento generalmente es quirúrgico. La cirugía puede ser abierta o percutánea. El objetivo de este estudio es evaluar los resultados clínico-funcionales en pacientes con roturas agudas del tendón de Aquiles tratados por técnica mínimamente invasiva de Dresden. Materiales y Métodos: Estudio prospectivo comparativo de 15 casos con roturas agudas del tendón de Aquiles. Se analizaron características del intraoperatorio, la hospitalización, los resultados funcionales y la evaluación de acuerdo con el puntaje de la AOFAS. El seguimiento promedio fue de 18 meses. Resultados: Se mencionan los resultados sobre la base del tiempo quirúrgico, la estadía hospitalaria, el tiempo hasta la cirugía, la carga del peso y el protocolo posoperatorio. El puntaje de la AOFAS a los 5 meses fue 94,66. El retorno a la actividad laboral fue, en promedio, a los 3.53 meses y el retorno a la actividad deportiva, a los 6.53 meses. Conclusiones: La técnica percutánea para la reparación de roturas agudas del tendón de Aquiles es una buena opción, los pacientes tienen una buena evolución y el índice de complicaciones es bajo. Nivel de Evidencia: IV

Introduction: The Achilles tendon ruptures are common traumatic injuries. Treatment is usually surgical. Surgery may be open or percutaneous. The aim of this study is to evaluate the clinical and functional outcomes in patients with acute Achilles ruptures treated by minimally invasive Dresden technique. Methods: Prospective study of 15 patients with acute Achilles tendon ruptures. Intraoperative characteristics, hospitalization, functional outcomes and evaluation according to AOFAS score were evaluated. The average follow-up was 18 months. Results: Results are listed based on the surgical time, hospital stay, time to surgery, weight load and postoperative protocol. The AOFAS score at five months was 94.66 points. Patients returned to work at 3.53 months on average and to their sport activities at 6.53 months Conclusions: The percutaneous technique for the repair of acute Achilles tendon rupture is a good choice.

RESUMEN

Haglund's syndrome produces posterior impingement of the heel, which is caused by a posterosuperior calcaneal exostosis, known as Haglund's deformity, associated with Achilles tendinitis and retrocalcaneal bursitis. Its pathogenesis is unknown. We report two cases that were diagnosed clinically and confirmed radiographically. One patient was treated conservatively and the other underwent surgery. The diagnosis is based on clinical signs and radiological images, using the measurement of the parallel pitch lines, in a lateral radiograph of the ankle. Initial treatment is usually conservative and includes anti-inflammatory or analgesic agents, physiotherapy and low-heeled, open-heeled shoes. If conservative treatment does not relieve the pain, surgery may be necessary.

RESUMEN

OBJECTIVE: To compare the mechanical failure of the Dresden technique for Achilles tendon repair with the double modified Kessler technique controlled repair technique. The maximum resistance of the two repair techniques are also compared. MATERIAL AND METHODS: A total of 30 Achilles tendon ruptures in bovine specimens were repaired with an Ethibond(®) suture to 4.5cm from the calcaneal insertion. Each rupture was randomly distributed into one of two surgical groups. After repair, each specimen was subjected to a maximum traction test. The mechanical failure (tendon, suture, or knot) rates (proportions) were compared using the exact Fisher test (α=.05), and the maximum resistances using the Student t test (α=.05). RESULTS: There was a difference in the proportions of mechanical failures, with the most frequent being a tendon tear in the Dresden technique, and a rupture of the suture in the Kessler technique. DISCUSSION: The repair using the Dresden technique performed in the open mode, compared to the Kessler technique, has a more suitable mechanical design for the repair of middle third Achilles tendon ruptures on developing a higher tensile resistance in 58.7%. However, its most common mechanical failure was a tendon tear, which due to inappropriate loads could lead to lengthening of the Achilles tendon.
