Luxaciones periastragalinas: análisis de una serie de casos. Nuestro algoritmo de tratamiento urgente / Subtalar dislocations: Analysis of a case series. Our urgent treatment algorithm

Introducción y objetivos: Las luxaciones periastragalinas son una entidad poco frecuente (<1%) de las lesiones traumáticas del pie. Se produce una pérdida de relación anatómica entre astrágalo, calcáneo y escafoides. Solo hay pequeñas series publicadas. Material y métodos: Presentamos los casos de una serie de pacientes (N=13) con luxaciones periastragalinas en los que se realizó un análisis descriptivo de las principales variables epidemiológicas, clínicas y radiológicas, a partir de las cuales se propone un algoritmo de tratamiento urgente. Se excluyeron los casos con fracturas del cuello del astrágalo, cuerpo del calcáneo o fracturas-luxación de Chopart aisladas. Resultados: La mediana de edad fue de 48,5 años con predominio del sexo masculino (69,23%). Cinco pacientes sufrieron caídas-entorsis sobre el tobillo y los 8 restantes mecanismos de alta energía. Las luxaciones mediales (9) predominaron sobre las laterales (4). Además, 4 pacientes presentaron luxaciones abiertas, 2 de ellas tipo IIIC que precisaron amputación. Se solicitó TC en un 76,93% de pacientes y 10 presentaron lesiones óseas asociadas del pie. Se realizó cirugía mediante reducción abierta en todas las lesiones abiertas y en un caso en el que fracasó la reducción cerrada. Cinco pacientes precisaron fijador externo tipo delta. Se objetivó esclerosis subcondral articular en un 77,77% de los casos; si bien solo uno precisó artrodesis subtalar. Conclusiones: Las luxaciones periastragalinas son una urgencia traumatológica y precisan una reducción precoz e inmovilización posterior. La fijación externa temporal transarticular es una buena opción de inmovilización en luxaciones abiertas. Son lesiones graves con alta probabilidad de artrosis precoz.(AU)

Introduction and objectives: Subtalar dislocations are a rare entity (<1%) in traumatic foot injuries. There is a loss of anatomical relationship between the talus, calcaneus and scaphoid. There are only small-published series. Material and methods: We present a series of patients (N=13) with subtalar dislocations in which a descriptive analysis of the main epidemiological, clinical and radiological variables was carried out, from which an urgent treatment algorithm is proposed. Cases with fractures of the neck of the talus, body of the calcaneus, or isolated Chopart fracture-dislocations were excluded. Results: The median age was 48.5 years with a predominance of males (69.23%). Five patients suffered falls or sprained ankles and the other eight suffered high-energy mechanisms. The medial dislocations (nine) predominated over the lateral ones (four). In addition, four patients presented open dislocations, two of them type IIIC that required amputation. CT scans were requested in 76.93% of patients and 10 presented associated bone lesions of the foot. Open reduction surgery was performed in all open lesions and in one case in which closed reduction failed. Five patients required a delta-type external fixator. Subchondral articular sclerosis was observed in 77.77% of cases; although only one required subtalar arthrodesis. Conclusions: Subtalar dislocations are a traumatic emergency that require early reduction and subsequent immobilization. Transarticular temporary external fixation is a good immobilization option in open dislocations. They are serious lesions with a high probability of early osteoarthritis.(AU)

Tratamiento quirúrgico del pie plano valgo adquirido del adulto en estadio IIB: papel de la reparación del «spring ligament» / Surgical treatment at adult acquired flatfoot stage IIB: Spring ligament repair

Antecedentes y objetivos: En el desarrollo del pie plano valgo adquirido del adulto ha cobrado gran importancia el fallo de la columna medial, y no tanto la rotura del tibial posterior, siendo principalmente la lesión del ligamento en hamaca calcaneonavicular (spring ligament) el determinante del desarrollo de esta deformidad. Nuestro objetivo es analizar los resultados clínico-radiológicos de la reparación del ligamento en hamaca y valorar la utilidad e integración de las cuñas de titanio poroso en las osteotomías a las que se asocia la reparación ligamentosa. Material y métodos: Realizamos un estudio retrospectivo de 23 casos con una edad media de 63 años, diagnosticados de pie plano valgo adquirido del adulto estadio IIB de la clasificación RAM tras fallo de tratamiento ortoprotésico, valorando los resultados clínicos mediante la escala de la American Orthopaedic Foot and Ankle Society y los resultados radiológicos pre- y postoperatorios basándose en la variación de los ángulos estudiados (cobertura talonavicular y ángulo talar - 1.° metatarsiano en la proyección dorsoplantar y línea de Meary en la proyección lateral). Resultados: Los puntuación media en escala de la American Orthopaedic Foot and Ankle Society pasó de 52±10 preoperatorio a 88±6 (p<0,05). En cuanto a los resultados radiológicos, se demostró una mejoría estadísticamente significativa (p<0,05) en la variación de los ángulos en el postoperatorio. Conclusiones: La reparación de los estabilizadores mediales, asociada a técnicas óseas ofrece excelentes resultados clínico-radiológicos en el tratamiento del pie plano valgo adquirido del adulto estadio IIB.Además, las cuñas de titanio poroso presentan una adecuada integración, evitando los problemas de pinzamiento de los peroneos asociada al uso de placas y la necesidad posterior de retirada.(AU)

Background and aims: The spring ligament has paramount role in supporting the arches and its fail causes the collapse of the medial longitudinal arc, inducing adult acquired flatfoot deformity. Our aim was to analyze the clinical and radiological outcomes of spring ligament repair and titanium wedges integration used in surgical osteotomies. Material and methods: We performed a retrospective study of 23 cases with middle ages of 63, diagnosed with adult acquired flatfoot deformity stage IIB in RAM classification after ortho-prosthetic treatment failure, assessing the functional outcomes using the American Orthopedic Foot and Ankle Society scale and the radiological outcomes studying angles variation (talonavicular uncoverage, talo-first metatarsal angle and Meary axis). Results: The mean preoperative American Orthopedic Foot and Ankle Society score of the sample was 52±10 and the postoperative 88±6 (p<0.05). The radiological outcomes showed a statistically significant improvement. Conclusion: Spring ligament repair associated to bone reconstruction offers large functional and radiological outcomes to adult acquired flatfoot deformity stage IIB treatment. Titanium wedges present an excellent bone integration.(AU)

Study of the functional results of the percutaneous surgical treatment of subtle injuries of the tarso-metatarsian complex. / Resultados funcionales del tratamiento quirúrgico percutáneo de las lesiones sutiles del complejo tarso-metatarsiano.

INTRODUCTION AND OBJECTIVES: The concept subtle Lisfranc defines low energy lesions of the tarsometatarsal joint complex (TMC) that involve joint instability. Often unnoticed, with long-term sequelae. The objective is to evaluate the clinical-functional results of patients with MTC ligament damage grade II-III (Nunley and Vertullo classification) treated with percutaneous surgery. MATERIAL AND METHODS: Retrospective study of 16 patients who underwent percutaneous surgery for MLC ligament damage. Demographic data, days of delay in diagnosis, surgical technique, joint reduction in load (adequate if C1-M2 space is less than 2 mm) and Manchester-Oxford scale (MOXFQ) score were collected. The sample consisted of nine males and seven females, mean age 43.6 years (17-71) and mean follow-up of 22 months (12-28). RESULTS: Diagnosis was delayed for more than 24 hours in four patients (3-6 days). In 11 patients the treatment consisted of closed reduction and percutaneous synthesis with cannulated screws from M2 to C1 and from C1 to C2. In three patients it was supplemented with Kirschner wires in the lateral radii. Two patients were treated with only M2 to C1 screws. An anatomical reduction was not achieved in six patients, with a mean of 2.6 mm between C1-M2 (2.1-3 mm); the mean functional MOXFQ score of these patients was 41.1% (IC 95% 23.1-59.1%), worse results compared to the anatomical reduction: 17.2% (IC 95% 5.7-28.7); statistically significant difference (p < 0.01). CONCLUSION: Subtle injuries from MTC are rare and can go unnoticed. Surgical treatment with percutaneous synthesis offers good clinical-functional results in the medium term. The anatomical reduction is a determining factor for the good functional result of our patients.

Study of the relation between the posterior malleolus fracture and the development of osteoarthritis. / Estudio de la relación de la fractura del maléolo posterior y el desarrollo de artrosis.

BACKGROUND AND AIMS: At least 10% of ankle fractures involve the posterior malleolus of the tibia, which has been related to poorer long-term prognosis. Our aim was to analyse the clinical and functional outcomes of ankle fractures involving the posterior edge, treated surgically without direct reduction of the third malleolus. MATERIAL AND METHODS: We performed a retrospective study of 45 patients aged under 60, who we classified into three groups in terms of the percentage of joint involvement of the posterior fragment (<10%, 10%-25% and >25%) assessing the functional outcomes using the visual analogue pain scale (VAS), the AOFAS scale (American Orthopedic Foot and Ankle Society) of the ankle and hindfoot and the global health questionnaire SF-36; we also analysed the degree of osteoarthritis with weight-bearing radiography, at least one year following the injury. RESULTS: The mean VAS pain score of the sample was 1.1 (0-5) at rest and 3 (0-8) on exercise; 88.4±10.1 on the AOFAS scale, and 68.5±19.3 points on the SF-36. Up to 18% of the patients developed radiographically significant osteoarthritis in the short and medium term (between 12 and 73months, with a mean of 33months). Of the patients, 55.6% had involvement of between 19% and 25% of the joint surface. We found that a larger posterior fragment size related to a greater degree of early-onset osteoarthritis (P<.03) and poorer AOFAS scores (P<.01). CONCLUSION: Ankle fractures involving the posterior malleolus seem to contribute to the development of early-onset osteoarthritis with functional limitation in young adults.

Osteosíntesis percutánea en fracturas de pilón tibial, ¿condiciona la técnica quirúrgica el resultado final? / Percutaneous osteosynthesis in tibial pilon fractures. Does the surgical technique determine the final result?

Objetivo. Analizar los resultados del tratamiento de las fracturas de tibia distal con o sin afectación intraarticular, tratadas con osteosíntesis percutánea mediante placas o tornillos canulados. Material y método. Estudio retrospectivo de 107 pacientes intervenidos entre 2001 y 2012. Criterios de inclusión: fracturas 43-A y 43-C1 y C2 según la clasificación AO, tratadas con osteosíntesis percutánea mediante placa bloqueada o 2 tornillos canulados en aspa. Se evaluaron 33 pacientes: 16 casos fueron sintetizados con placa bloqueada (G1) y 17 con tornillos canulados (G2). El tiempo medio hasta cirugía fue de 8,31 días (0-14) en G1 y de 2 días (0-7) en G2. La media de seguimiento fue de 72 meses (12-132). Tiempo medio hasta consolidación: 17,08 semanas (8-48) en G1 y 14,56 semanas (8-24) en G2. Los resultados se evaluaron según la escala AOFAS, radiografías simples y complicaciones durante el seguimiento. Resultados. La valoración media según la AOFAS fue de 78,62 en G1 (22-93) y 90,63 en G2 (70-100), siendo esta diferencia estadísticamente significativa. En G1 el 61,4% (8) de los resultados fueron excelentes o buenos, mientras que en G2 lo fueron el 76% (13). Ausencia de casos con deformidad axial y acortamientos. Se registraron 4 infecciones superficiales y una rotura de material en G1. Discusión. La osteosíntesis percutánea con tornillos canulados supone una alternativa adecuada para el manejo de fracturas tibiales sin gran componente articular con mejores resultados que la síntesis con placas. El menor tiempo desde el traumatismo hasta la intervención en este grupo mejora la evolución de partes blandas, siendo significativo en el resultado final (AU)

Objetive. To analyze the outcomes of distal tibia fractures with or without extension into the ankle joint, treated by percutaneous cannulated screws or locking plates. Material and methodmethod. A retrospective study was conducted on 107 patients treated between 2001 and 2012. Inclusion criteria: fractures 43-A and 43-C1 and C2 according to the AO/OTA system, treated with percutaneous osteosynthesis by locking plate or two cannulated screws in X -letter setting. A total of 33 patients were evaluated: 16 tibial fractures were performed with locking plate (G1) and 17 with cannulated screws (G2). Mean time to surgery was 8.31 days (0-14) in G1, and 2 days (0-7) in G2. The mean follow-up was 72 months (12-132). Mean time to healing: 17.08 weeks (8-48) in G1, and 14.56 weeks (8-24) in G2. The results were evaluated according to the AOFAS scale, with plain X-rays, and complications during follow-up. Results. The mean evaluation according to the AOFAS score was 78.62 in G1 (22-93), and 90.63 in G2 (70-100), and this was statistically significant. In G1, 61.4% (8) of the results were excellent or good, while in G2 it was 76% (13). There were no axial deformity cases or shortenings. There were 4 superficial infections and one broken device recorded in G1. Discussion. The percutaneous cannulated screw fixation is a suitable alternative for the management of fractures without significant joint involvement, and seems to offer better functional results than plates. The shortest time from injury to intervention in this group improves the progress of the soft tissues, and can improve the final result (AU)
