Complicated Bosworth fracture-dislocation: A case report and review of the literature / 中华创伤杂志(英文版)

Bosworth fracture and dislocation is relatively rare, accounting for about 1% of ankle fractures. It is characterized by the proximal fibula fracture embedded in the posterolateral distal tibia. Due to an insufficient understanding of this fracture, it is easy to cause missed diagnosis and misdiagnosis in clinical practice. Due to the insertion of the fracture, it is challenging to perform closed reduction, and improper treatment is easy to cause complications. Surgical treatment is recommended for this type of fracture. In order to improve the understanding of orthopedic surgeons about Bosworth fracture and dislocation, this paper reports the diagnosis and treatment of 2 cases of Bosworth fracture and dislocation, and reviews the literature on Bosworth fracture's mechanism, diagnosis, classification, complications, and treatment options in recent years.

A retrospective study on manual reduction combined with Chinese Orthopaedic ankle external fixator in the treatment of trimalleolar fracture / 中国骨伤

OBJECTIVE@#To evaluate the needle puncture safety and clinical efficacy of manual reduction combined with external fixation of ankle frame in the treatment of trimalleolar fracture under the guidance of Chinese Osteosynthesis (CO) theory.@*METHODS@#The clinical data of 118 patients with trimalleolar fractures admitted from December 2010 to December 2021 were retrospectively analyzed. Fifty-three patients were treated with manual reduction combined with external fixation of ankle frame(observation group). Sixty-five patients were treated with open reduction and internal fixation with plate and screws(control group). The operation time, hospitalization days, non-weight-bearing time of the affected limb, clinical healing time of fracture, incidence of complications, visual analogue scale (VAS) before and 1 month after operation, and American Orthopedic Foot and Ankle Society(AOFAS) score of ankle joint before and 1 year after operation were compared between the two groups.@*RESULTS@#Patients in both groups were followed up for more than 1 year. All patients were followed up, and the duration ranged from 14 to 70 months, with an average of(35.28±14.66) months. There were statistically significant in operation time, hospitalization days, non-load-bearing time of affected limbs, clinical healing time of fractures and VAS score one month after operation between the two groups. One month after operation, the VAS score of the observation group was lower than that of the control group(t=3.343, P=0.001). The operation time of the observation group was significantly shorter than that of the control group(t=9.091, P=0.000). The hospitalization days in the observation group were significantly less than those in the control group(t=5.034, P=0.000). The non-load-bearing time of the affected limb in the observation group was significantly shorter than that in the control group(t=11.960, P=0.000). The clinical healing time of fracture in the observation group was significantly shorter than that in the control group(t=4.007, P=0.000). There was no significant difference in AOFAS score between the two groups one year after operation(t=0.417, P=0.678). In the observation group, there were 2 cases of pinhole infection and 3 cases of loss of reduction less than 2 mm. There were 3 cases of surgical incision infection in the control group. There was no significant difference in the incidence of complications between the two groups(χ2=0.446, P=0.504).@*CONCLUSION@#Manual reduction combined with external fixation is safe and effective in the treatment of trimalleolar fracture under the guidance of CO theory, and the function of ankle joint recovers well after operation. This therapy has good clinical value.

Conservative treatment of supination and external rotation for type Ⅲ and Ⅳankle fracture by bone setting / 中国骨伤

OBJECTIVE@#To explore curative effect of conservative treatment of supination-lateral rotation (SER) with type Ⅲ and Ⅳ ankle fracture by bone setting technique.@*METHODS@#From January 2017 to December 2019, 64 patients diagnosed with SER with type Ⅲ and Ⅳ ankle fracture were treated with manipulative reduction and conservative treatment (manipulation group) and surgical treatment with open reduction and internal fixation (operation group), 32 patients in each group. In manipulation group, there were 17 males and 15 females, aged from 15 to 79 years old with an average of (51.42±13.68) years old;according to Lauge-Hansen classification, there were 8 patients with supination external rotation type Ⅲ and 24 patients with type Ⅳ. In operation group, there were 13 males and 19 females, aged from 18 to 76 years old with an average of (47.36±15.02) years old;7 patients with type Ⅲ and 25 patients with type Ⅳ. Displacement of ankle fracture was measured by Digimizer software, and compared before treatment, 3 and 12 months after treatment between two groups. Lateral medial malleolus displacement, lateral medial malleolus displacement, lateral malleolus displacement, lateral malleolus displacement, lateral malleolus contraction displacement and posterior malleolus displacement were measured and compared between two groups. Mazur score was used to evaluate ankle joint function.@*RESULTS@#All patients were followed up from 12 to 36 months with an average of (17.16±9.36) months. There were statistical differences in lateral medial malleolus displacement, lateral medial malleolus displacement, lateral malleolus displacement, lateral malleolus displacement, lateral malleolus contraction displacement and posterior malleolus displacement in manipulation group before and after reduction(P<0.05). Compared with operation group, there were no statistically significant differences in lateral malleolus shift, lateral malleolus shift, lateral malleolus contraction shift(P>0.05), while there were statistically significant differences in lateral malleolus shift, posterior malleolus shift up and down (P<0.05). Mazur scores of ankle joint at 3 months after treatment in manipulation group and operation group were 68.84±13.08 and 82.53±7.31, respectively, and had statistical differences(P<0.05), while there was no difference in evaluation of clnical effect(P>0.05). There were no differences in Mazur score and evaluation of clnical effect between two groups at 12 months after treatment (P>0.05).@*CONCLUSION@#Bone setting technique could effectively correct lateral displacement of medial malleolus, lateral displacement of medial malleolus, lateral displacement of lateral malleolus and lateral contraction displacement of lateral malleolus in supination lateral rotation type Ⅲ and Ⅳ ankle fracture, and has good long-term clinical effect, which could avoid operation for some patients and restore ankle function after fracture.

Comparison of posterolateral approach and combined approach in treatment of Mason type 2B posterior malleolar fracture / 中国修复重建外科杂志

OBJECTIVE@#To compare the effectiveness between the posterolateral approach and the posterolateral combined posteromedial approaches in the treatment of Mason type 2B posterior malleolar fracture.@*METHODS@#A retrospective analysis was performed on the clinical data of 79 patients with posterior ankle fracture who met the selection criteria between January 2015 and January 2022. There were 62 cases of Mason 2B Pilon subtype and 17 cases of avulsion subtype. Among Mason 2B Pilon subtype patients, 35 were treated with posterolateral approach (group A), 27 patients were treated with combined approach (group B). There was no significant difference in gender, age, injured side, cause of injury, time from injury to operation, preoperative hospital stay, preoperative visualanalogue scale (VAS) score, and intraoperative internal fixation between the two groups ( P>0.05). All patients with Mason 2B avulsion subtype were treated by posterolateral approach, including 7 males and 10 females, aged from 25 to 68 years, with an average of 46.1 years. The operation time, intraoperative blood loss, postoperative hospital stay, and complications were recorded. The reduction quality was evaluated by Ovadia deals radiographic score, and the ankle function and pain were evaluated by VAS score, American Orthopaedic Foot and Ankle Society (AOFAS) score, and ankle range of motion.@*RESULTS@#Mason 2B Pilon subtype: There was no significant difference in operation time, intraoperative blood loss, postoperative hospital stay, and follow-up time between the two groups ( P>0.05). The radiological evaluation of Ovadia deals in group A was significantly worse than that in group B ( P<0.05). The VAS score in the two groups significantly improved at each time point after operation, and the VAS score and AOFAS score further improved with the extension of time after operation, and the differences were significant ( P<0.05). Except that the AOFAS score of group A was significantly lower than that of group B at last follow-up ( P<0.05), there was no significant difference in VAS score and AOFAS score between the two groups at other time points ( P>0.05). At last follow-up, the ankle range of motion in group A was significantly less than that in group B ( P<0.05). There was no significant difference in the incidence of sural nerve injury, deep tissue infection, limitation of toe movement, and traumatic ankle arthritis between the two groups ( P>0.05). Mason 2B avulsion subtype: The operation time was (119.47±20.61) minutes and the intraoperative blood loss was 50 (35, 55) mL. Seventeen patients were followed up 13-25 months, with an average of 18 months. The Ovadia deals score was excellent in 10 cases, good in 6 cases, and poor in 1 case at 1 week after operation, and the excellent and good rate was 94.1%. All fractures healed in 8-18 weeks with an average of 12.35 weeks. There were 1 case of sural nerve injury and 3 cases of traumatic ankle arthritis after operation. No deep tissue infection or limitation of toe movement occurred. The VAS score decreased significantly and AOFAS score increased significantly with time, and the differences were significant between different time points before and after operation ( P<0.05). The ankle range of motion at last follow-up was (56.71±2.47)°.@*CONCLUSION@#Compared with the posterolateral approach, the combined approach is a better choice for the treatment of Mason 2B Pilon subtype. If the posteromedial bone block does not affect the reduction of the medial malleolus, the posterolateral approach can achieve good effectiveness for Mason 2B avulsion subtype.

Analysis of the efficacy of a modified posteromedial approach for Klammer III posterior Pilon fractures / 中华创伤杂志(英文版)

PURPOSE@#To analyze the curative effect and technical points of a modified posteromedial approach in the treatment of Klammer III posterior Pilon fracture.@*METHODS@#A retrospective analysis of patients with Klammer III posterior Pilon fractures were conducted in our department from January 2018 to December 2019. Before the surgery, the patients were fully relieved of swelling and pain, and a comprehensive examination was carried out. The posteromedial approach exposed the posterior and medial fracture block of the distal tibia. According to the fracture of external malleolus, it is determined whether to combine a lateral incision and protect tendons and vascular nerves by a retractor, and then perform a fracture reduction and internal fixation. Postoperatively, the patients were treated with analgesia, detumescence, anticoagulation and rehabilitation exercise. The American orthopaedic foot and ankle society (AOFAS) score and visual analogue score were recorded at regular follow-up after surgery. A t-test was used for the comparison of the preoperative and final AOFAS score.@*RESULTS@#There were 7 male and 13 female (n = 20) included in the study, aged 22 to 88 years (average age 54.2 years). The injury mechanisms were falling from a height (n = 7), traffic accident (n = 6), walking injury (n = 2) and heavy injury (n = 5). The postoperative follow-up duration was 12-24 months (mean 16.95 months). The AOFAS score of the 20 patients before and after surgery were compared. The preoperative AOFAS score was 38.90 ± 3.91, and the final AOFAS score was 80.55 ± 4.20, (p < 0.001). The mean final visual analogue scores at rest, active and weight-bearing walking were 0.30, 0.85 and 1.70, respectively. One patient reported poor postoperative wound healing and required a return to hospital for debridement and anti-infection treatment.@*CONCLUSION@#In the treatment of Klammer III posterior Pilon fractures, the modified posteromedial approach can fully expose the fracture block and the collapsed articular surface of the medial malleolus, achieve good reduction and internal fixation with limited injury of the tendon and vascular nerves, and have a better prognosis.

Clinical results of modified medial approach in the treatment of Pilon fracture with medial column compression / 中国骨伤

OBJECTIVE@#To explore the clinical results of modified medial incision in the treatment o f Pilon fracture with medial column compression and evaluate its safety.@*METHODS@#Thirty-one patients of Pilon fracture with medial column compressiom accepted surgical treatments in the Department of Foot and Ankle at Honghui Hospital of Xi'an Jiaotong University from January 2015 to January 2019. According to the imaging data at admission, 31 cases were diagnosed as closed Pilon fractures, and both preoperative X-ray and 3D CT scan were shown as medial column compressive fractures. All patients underwent modified medial incision with complete data, including 23 males and 8 females;ranging in age from 22 to 65 years old, with an average of (39.5±16.2) years old. All patients underwent modified medial approach combined with other approaches to expose the broken end of fracture. The time from trauma to operation ranging from 7 to 20 days, with a mean of(9.5±5.5) days. The incision and fracture healing were followed up regularly after operation.@*RESULTS@#All patients were followed up with an average of(15.7±5.5) months(ranged, 13 to 25 months). Preoperative and postoperative routine X-ray and 3D CT examination showed anatomical reduction in 8 cases, and the anatomical reduction rate was 25.81%. Up to the latest follow-up, all 31 fractures had achieved bone healing, and the healing time ranged from 11 to 22 weeks, with a mean of (14.3±4.7) weeks. At the latest follow-up, the American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot scores ranged from 75 to 89, with a mean of 80.5±4.9, 24 patients got a good result, 7 fair.@*CONCLUSION@#The improved medial approach for Pilon fracture can directly expose the posterior medial, medial and anterior medial of the distal tibia. After reduction under direct vision, the medial compressed and collapsed articular surface are fixed. The clinical curative effect is satisfactory and the wound complications are less. It is recommended for Pilon fracture where compression of the medial articular surface is predominant.

Tratamiento de una fractura-luxación del tobillo mediante la fijación externa RALCA. Seguimiento de cinco años / Treatment of an ankle fracture-dislocation using RALCA external fixation. Five-year monitoring

RESUMEN La fractura luxación del tobillo se presenta con alguna frecuencia en la práctica médica. La asociación de una luxación en las fracturas de tobillo modifica su abordaje terapéutico puesto que la articulación no debe permanecer por más de seis horas en dicha situación y por ende se requerirá del tratamiento quirúrgico de urgencia. Son conocidas las complicaciones relacionadas con la no reducción de una luxación en el periodo de tiempo mencionado anteriormente, dentro de estas, la necrosis avascular del astrágalo representa la más temida debido a la incapacidad que genera. Por tales razones se decidió presentar un caso que muestra el tratamiento de una fractura -luxación del tobillo derecho, en una paciente de 30 años de edad, estabilizada mediante el empleo de un mini fijador RALCA, la cual fue seguida por un periodo de cinco años.

ABSTRACT Ankle fracture dislocation occurs with some frequency in medical practice. The association of a dislocation in ankle fractures modifies its therapeutic approach since the joint should not remain for more than six hours in this situation and therefore emergency surgical treatment will be required. Complications related to the non-reduction of a dislocation in the previously mentioned period of time are known; within these, avascular necrosis of the talus represents the most feared due to the disability it generates. For these reasons, it was decided to present a case that shows the treatment of a fracture -luxation of the right ankle, in a 30-year-old patient, stabilized by using a RALCA mini fixator, which was followed for a period of five years.

Manejo terapéutico del maléolo posterior en fracturas trimaleolares de tobillo: revisión bibliográfica / Therapeutic management of the posterior malleolus in trimaleolar ankle fractures: review / Manejo terapêutico do maléolo posterior em fraturas do tornozelo trimaleolar: revisão bibliográfica

Introducción: El manejo terapéutico de las fracturas de maléolo posterior en las fracturas trimaleolares de tobillo continúa en debate. Nuestro objetivo fue realizar una búsqueda de la evidencia científica sobre los aspectos terapéuticos de las fracturas de maléolo posterior en el contexto de las fracturas trimaleolares. Materiales y métodos: Se realizó una revisión de la bibliografía sistematizada por dos revisores, centrados en el manejo terapéutico del maléolo posterior. Resultados: Se obtuvieron 16 artículos clínicos de un total de 1029 pacientes, 8 estudios nivel de evidencia II y 8 de nivel IV. Se sistematizaron las indicaciones quirúrgicas y se analizaron los resultados funcionales y las complicaciones. Conclusiones: La comprensión pato-anatómica de estas fracturas es cada día mayor, principalmente por la utilización habitual de tomografías computarizadas (TC). El tratamiento quirúrgico sobre el maléolo posterior está evidenciando buenos y excelentes resultados funcionales. Para una adecuada decisión terapéutica se debería tener en cuenta ciertos factores: inestabilidad tibiotalar y sindesmótica, congruencia articular y características morfológicas del maléolo posterior. La reducción abierta (RA) y fijación interna con placa de sostén es el tratamiento que ha demostrado mejores resultados a corto y mediano plazo, no encontrando estudios con seguimiento a largo plazo.

Introduction: The therapeutic management of posterior malleolus fractures in trimaleolar ankle fractures continues in debate. Our objective was to conduct a search for scientific evidence on the therapeutic aspects of posterior malleolus fractures in the context of trimaleolar fractures. Materials and methods: A review systematic of the literature was carried out by two reviewers, focusing on the therapeutic management of the posterior malleolus. Results: 16 clinical articles were obtained with a total of 1029 patients, 8 studies level of evidence II and 8 studies level IV. The surgical indications were systematized, and the functional results and complications were analyzed. Conclusions: The patho-anatomical understanding of these fractures is increasing every day, mainly due to the usual use of CT scans. Surgical treatment on the posterior malleolus shows good and excellent functional results. For an adequate therapeutic decision certain factors should be taken into account: tibiotalar and syndesmotic instability, joint congruence and morphological characteristics of the posterior malleolus. Open reduction and internal fixation with support plate is the treatment that has shown better results in the short and medium term, not finding studies with long-term follow-up.

Haste intramedular de fíbula nas fraturas maleolares do tornozelo - técnica cirúrgica e revisão da literatura / Intramedullary nailing of lateral malleolus in ankle fractures - surgical technique and literature review

RESUMO Nosso objetivo é descrever a técnica de fixação intramedular (IM) da fíbula no tratamento cirúrgico das fraturas maleolares do tornozelo. A redução é realizada sempre de forma percutânea: quando o traço de fratura é oblíquo simples, utilizamos uma pinça de redução de pontas e quando a fratura apresenta padrão multifragmentar, usa-se tração longitudinal e rotação. Isso reduz as complicações relacionadas à redução aberta e fixação interna com placa. A técnica demonstrou ser simples e reprodutível. Além disso, essa forma de fixação permite apoio precoce do peso corporal, o que acelera o processo de reabilitação e potencialmente acelera a cicatrização da fratura. A fixação IM da fíbula mostrou-se uma opção viável para a fixação do maléolo lateral nas fraturas do tornozelo, devendo ser considerada no arsenal do cirurgião.

ABSTRACT Our objective is to describe the technique of intramedullary (IM) nailing of lateral malleolus in the surgical management of ankle fractures. Fracture reduction is performed either percutaneously with a small pointed reduction clamp in simple oblique fractures or using longitudinal traction and rotation for comminuted fractures, thus reducing complications related to open reduction and internal fixation with a plate. The technique has been shown to be simple and reproducible. In addition, the technique allows early weight bearing, which accelerates rehabilitation and potentially fasten fracture healing. IM nailing is a viable option for the fixation of the of lateral malleolus in ankle fractures and should be considered in the surgeon's armamentarium.

Introducción: La Organización Mundial de la Salud define como persona anciana a toda aquella de entre 75 y 90 años, y los que sobrepasan esta edad se denominan personas de edad muy avanzada. El objetivo de este estudio fue analizar los resultados posoperatorios de las fracturas de tobillo tratadas con técnicas MIPO, y de reducción abierta y fijación interna (RAFI), en las que se logró una reducción funcional y biológica en pacientes >75 años. Materiales y Métodos: Entre 2013 y 2017, se evaluó a 13 pacientes >75 años con fractura inestable de tobillo. Seis fueron operados con técnica MIPO y siete, con RAFI. Todos fueron evaluados a los 90 días y a los 18 meses de la cirugía mediante el puntaje de la AOFAS. Resultados: La edad promedio era de 79.7 años (rango 75-95). El puntaje global de la AOFAS fue 97 a los 90 días y 96 a los 18 meses. No se observaron pérdidas de reducción ni vicios de ejes. Conclusión: Nuestro estudio indica que la reducción biológica y funcional en pacientes >75 años es el tratamiento ideal para las fracturas de tobillo. Nivel de Evidencia: IV

Introduction: The World Health Organization defines an elderly person as anyone who is between 75 and 90 years of age, while those older are called old people. The objective of this study was to discuss postoperative results of ankle fractures treated with MIPO and ORIF techniques, achieving a functional and biological reduction in patients older than 75 years. Methods: Between 2013 and 2017, 13 patients beyond the age of 75 with unstable ankle fractures were evaluated. Six were treated with MIPO technique and 7 with ORIF. All patients were evaluated at 90 days and at 18 months postoperatively using the AOFAS score. Results: Mean age was 79.7 years (range 75-95). Overall postoperative AOFAS score was 97 at day 90 and 96 at 18 months. No losses of reduction or shaft defects were observed. Conclusion: Our study indicates that biological and functional reduction in patients older than 75 years is the ideal treatment for ankle fractures. Level of Evidence: IV

Funcionalidad y estabilidad del tratamiento de la fractura de tobillo B de Weber con lesión deltoidea a nivel sindesmal dependiendo del nivel de colocación del tornillo transindesmal (2. 0 o 3. 5 cm) / Functionality and stability of the treatment of Weber B ankle fractures with syndesmotic injury depending on the placement level of the screw (2. 0 versus 3. 5 cm)

Resumen: Introducción: La fractura del tobillo es una de las lesiones más frecuentes del sistema musculoesquelético; existen estudios de población que reportan un aumento en la incidencia de estas fracturas a partir de los años 70 asociado al incremento en la difusión a través de los medios de las actividades deportivas de contacto. Las fracturas trans- y suprasindesmales afectan la sindesmosis y, de no tratarse adecuadamente, dejarán inestabilidad articular. El tratamiento más común es la colocación de un tornillo; existe controversia en la altura a la que este se debe colocar con respecto a la línea articular tibioastragalina. Material y método: Estudio descriptivo, observacional, retrospectivo y transversal de expedientes clínicos y radiográficos de pacientes operados de fractura bimaleolar; se les dividió en dos grupos: aquellos con el tornillo transindesmal a 2 o 2.5 cm y aquellos con el tornillo a 3.5 cm o más proximal. Se recolectaron 34 casos en total (grupo A: 16 pacientes; grupo B: 18), 22 del sexo masculino y 12 del femenino, de edades entre 19 y 45 años. Resultados: Se aplicó la escala funcional de Olerud-Molander y se midió el claro medial del tobillo para considerar el grado de reducción de la sindesmosis. Se compararon los resultados de ambos grupos. Discusión: El sitio de localización del tornillo de situación a 2.0 cm presentó un porcentaje de 75% de estabilidad articular y 25% de inestabilidad articular, la funcionalidad articular fue relativamente menor en comparación con la colocación del tornillo a 3.5 cm, donde se logró una estabilidad articular de 83.3% y 16.3% de inestabilidad articular.

Abstract: Background: Ankle fractures are one of the most frequent lesions of the musculoskeletal system; there are studies that report an increase in the incidence of these fractures starting in the 1970s, associated with the increased media outreach of sporting activities. Supra- and transyndesmal fractures often lead to injury of the syndesmosis, which, if not treated properly, will leave joint instability. The most common treatment is the placement of a transyndesmal screw; there is controversy on the height in which it should be located with regard to the distal tibial joint line. Material and method: A descriptive, observational, retrospective and transversal study with clinical and radiographic records of patients operated on bimalleolar fractures; they were divided into two groups: those with the transyndesmal screw at 2 or 2.5 cm and those with the screw at 3.5 cm or more proximal. There was a total of 34 cases (group A: 16 patients; group B: 18), 22 male and 12 female, aged between 19 and 45 years. Results: We applied the Olerud-Molander ankle score for the clinical evaluation and measured the radiographic medial space of the ankle to consider the degree of reduction. The results in both groups were compared. Discussion: The location of the screw at 2.0 cm presented a percentage of 75% of joint stability and 25% of joint instability, the joint functionality was relatively smaller in comparison to the placement of the screw at 3.5 cm, with which we achieved a joint stability of 83.3% and 16.3% of joint instability.

Comparación funcional en el tratamiento de las fracturas de tobillo B de Weber con implante y sutura versus tornillo situacional / Functional comparison in the treatment of Weber type B ankle fractures with suture device versus screw

Resumen: Antecedentes: Diez por ciento de todas las fracturas de tobillo, 20% de las fracturas tratadas quirúrgicamente y de 1 al 18% de los esguinces presentan lesión de la sindesmosis. Los métodos utilizados para su reducción son tornillos situacionales metálicos o bioabsorbibles, reparación directa y el uso de suturas con o sin botones. El objetivo de este trabajo fue comparar la función clínica de las fracturas de tobillo B de Weber tratadas con TightRope o con el uso de tornillo situacional. Material y métodos: Se realizó un estudio observacional, comparativo, transversal en el período comprendido de Marzo del 2012 a Marzo del 2015. Se utilizó la escala de AOFAS de tobillo para valorar la función de pacientes con fracturas Weber B con lesión de sindesmosis tratados con tornillo situacional tricortical de 3.5 mm y pacientes tratados con sistema TightRope. Resultados: Se estudiaron 43 pacientes con una media de 47 años de edad. Se realizó la prueba de ANOVA de un factor para comparar los resultados de ambos grupos observando que a los tres, seis y 12 meses el grupo de TightRope presentó una mejoría significativa en cuanto al puntaje de AOFAS en comparación con el grupo de tornillo situacional (p = 0.05). Discusión: El uso del sistema TightRope presenta mejor función clínica en comparación con el tornillo situacional tricortical de 3.5 mm en el corto plazo, de acuerdo con la escala de AOFAS.

Abstract: Background: Ten percent of all ankle fractures, 20% of the fractures treated surgically, and 1-18% of all sprains involve a syndesmosis injury. The methods used for reduction are metal or bioabsorbable syndesmotic set screws, direct repair, and sutures with or without buttons. The purpose of this study was to compare the clinical function of patients who sustained Weber B ankle fractures and were treated with the TightRope system or a syndesmotic set screw. Material and methods: An observational, comparative, cross-sectional study was conducted between March 2012 and March 2015. The AOFAS ankle scale was used to assess function in patients with Weber B fractures with a syndesmosis injury treated with a 3.5 mm tricortical set screw or with the TightRope system. Results: Forty-three patients were included, their mean age was 47 years. The single-factor ANOVA test was used to compare the results of both groups. The latter showed that at 3, 6 and 12 months the TightRope group showed a significant improvement based on the AOFAS score, compared with the set screw group (p = 0.05). Discussion: The use of the TightRope system results in better clinical function in the short term compared with the 3.5 mm tricortical set screw, according to the AOFAS scale.

Artroscopía del tobillo en el tratamiento de la fractura de Bosworth / Ankle arthroscopy in treatment of Bosworth fracture

Resumen: La fractura de Bosworth corresponde a un patrón de fractura-luxación del tobillo con luxación fija del segmento proximal de la fíbula posterior al maléolo posterior de la tibia. Es una lesión poco frecuente que requiere un alto índice de sospecha para su diagnóstico. La luxación fija de la fíbula impide la reducción cerrada, por lo que se impone una reducción abierta y la osteosíntesis de los fragmentos de fíbula y/o tibia. Presentamos un caso clínico de una paciente que sufrió esta lesión asociada a fractura del maléolo interno; fue sometida a tratamiento quirúrgico, asimismo se procedió a la artroscopía anterior del tobillo para evaluar la estabilidad de la sindesmosis, exéresis de fragmentos osteocondrales libres, desbridamiento y microfracturas de lesiones condrales inestables del astrágalo. Un año después la paciente permanece con dolor residual ocasional y un rango de movimiento normal comparado con el tobillo contralateral. La fractura de Bosworth es una lesión grave y poco frecuente que requiere un diagnóstico precoz y tratamiento quirúrgico urgente. La utilización de la artroscopía en su tratamiento agudo permite el diagnóstico y tratamiento de la patología intraarticular asociada y asiste en la evaluación de la reducción adecuada de la fractura y de la estabilidad de la sindesmosis tibiofibular.

Abstract: The Bosworth fracture is a pattern of fracture-dislocation of the ankle joint with fixed dislocation of the proximal part of the fibula behind the posterior malleolus. It is a rare injury, which requires high index of suspicion for diagnosis. Fixed dislocation of the fibula does not allow for closed reduction, so open reduction and fixation of fibula or tibia is required. We present a case report of a patient who suffered a Bosworth fracture, with associated medial malleolus fracture. She underwent surgical treatment with open reduction and internal fixation of the fibula and tibia. We also performed anterior arthroscopy of the ankle, to evaluate the tibiofibular syndesmosis, remove loose osteochondral fragments, and perform debridement and microfracture of unstable chondral lesions of the talus. One year after injury, she remains with occasional pain and a normal range of motion comparing to the contralateral ankle joint. Bosworth fracture is a serious and rare injury, which requires early diagnosis and urgent surgical treatment. Performing ankle arthroscopy in the acute treatment of the Bosworth fracture allows for diagnosis and treatment of associated intra-articular injuries, as well as assisting with adequate fracture reduction and evaluation of the tibiofibular syndesmosis stability.

Fractura de tobillo en adolescentes: fractura triplanar de tobillo asociada a fractura de pierna / Ankle fracture in adolescents: triplanar injury associated to fracture of leg

Resumen: Introducción: la gran mayoría de fracturas epifisiarias pediátricas pueden categorizarse según la clasificación de Salter Harris. Existen otros tipos de patrones como la fractura triplanar y la de Tillaux, la primera es un patrón de fractura complejo con rasgos de fractura en planos sagital, transverso y frontal. Estos tipos de fractura pueden estar asociados a complicaciones importantes como cierre fisiario precoz, desejes y alteraciones de la marcha. Presentamos el caso de un paciente que además de tener una fractura triplanar presentó una fractura de pierna ipsilateral, este complejo escenario de rara ocurrencia fue tratado mediante reducción y osteosíntesis de ambas fracturas. Presentamos este caso para ayudar en el manejo de estas lesiones que como consecuencia de las actividades deportivas a edades tempranas pueden tornarse cada vez más frecuentes.

Abstract: Introduction: the vast mayority of epiphyseal children fractures could be classified according to Salter Harris. There are other types of patterns such as triplanar and Tillaux fractures. The former is a complex type with fracture lines in sagital, axial and frontal planes. These fractures have main complications such as early epiphyseal closure, mechanical axis malalignment and gait disturbances. A clinical case is pictured which had a tibial shaft and ipsilateral triplanar fracture, this complex scenario of rare ocurrence was treated with reduction and osteosynthesis of both fractures. This clinical case is shown to help in the management of these injuries that with the early sport practice initiation, could appear more frequently.
