Study of the clinical and functional results of open calcaneoplasty and tendinous repair for the treatment of the insertional tendinopathy of the Achilles' tendon. / Estudio de los resultados clínico-funcionales de la calcaneoplastia abierta y reparación tendinosa con sistema de cinta y doble hilera en el tratamiento de la tendinopatía insercional del tendón de Aquiles.

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.

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

INTRODUCCIÓN Y OBJETIVOS: El concepto Lisfranc sutil define lesiones por baja energía del complejo articular tarso-metatarsiano (CTM) que suponen inestabilidad articular. Con frecuencia pasan desapercibidas, con secuelas a largo plazo. El objetivo es evaluar los resultados clínico-funcionales de los pacientes con lesiones CTM ligamentosas grado II-III (clasificación de Nunley y Vertullo) tratados con cirugía percutánea. MATERIAL Y MÉTODOS: Estudio retrospectivo sobre 16 pacientes intervenidos percutáneamente por lesión ligamentosa CTM. Se recogieron datos demográficos, días de demora del diagnóstico, técnica quirúrgica, reducción articular en carga (adecuada si espacio C1-M2 menor de 2 mm) y puntuación de la escala Manchester-Oxford (MOXFQ). Muestra constituida por nueve varones y siete mujeres, edad media de 43,6 años (17-71) y seguimiento medio 22 meses (12-28). RESULTADOS: El diagnóstico se demoró más de 24 horas en cuatro pacientes (3-6 días). En 11 pacientes el tratamiento consistió en reducción cerrada y síntesis percutánea con tornillos canulados desde M2 a C1 y desde C1 a C2. En tres pacientes se suplementó con agujas Kirschner en los radios laterales. Dos pacientes se trataron con único tornillo M2 a C1. No se consiguió una reducción anatómica en seis pacientes, con una media de 2,6 mm entre C1-M2 (2,1-3 mm); la puntuación media funcional MOXFQ de estos pacientes fue 41,1% (IC 95% 23,1-59,1%), peores resultados comparando con la reducción anatómica: 17,2% (IC 95% 5,7-28,7); diferencia estadísticamente significativa (p < 0,01). CONCLUSIÓN: Las lesiones sutiles del CTM son poco frecuentes y pueden pasar desapercibidas. El tratamiento quirúrgico con síntesis percutánea ofrece buenos resultados clínico-funcionales a medio plazo. La reducción anatómica es un factor determinante para el buen resultado funcional de nuestros pacientes

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

Obturator dislocation of total hip arthroplasty with disassembly of the prosthesis components and periprosthetic fracture in morbid obese patient.

INTRODUCTION: Anterior dislocation is a rare complication of total hip arthroplasty (THA). There exist only three cases in the literature. None of them report disassembly of the prosthesis components. We present a morbidly obese woman who suffered an irreducible obturator dislocation of an infected total hip arthroplasty (THA), due to uncontrolled adduction during an early debridement surgery. Following unsuccessful closed reduction attempts, a Vancouver B2 periprosthetic fracture and disassembly of the prosthetic components were observed. Two-stage revision THA was necessary to resolve the infection and restore hip functionality. In obturator dislocation, the femoral head prosthetic can be trapped in the obturator foramen, and this may disassemble the prosthesis components during reduction maneuvers; theres also risk of periprosthetic fracture. This mandate an open reduction of the joint. Patient obesity could be a determining factor for this rare type of hip arthroplasty dislocation. Obturator dislocation is an extremely rare complication of the total hip arthroplasty, whose reductions should be handled with caution given the risks of periprosthetic fractures. In most cases, an open reduction of the joint is required. CLINICAL IMPORTANCE: Our work is likely to be of great interest because it offers tips for the management of this rare complication based on our experience.

INTRODUCCIÓN: La luxación anterior es una complicación poco frecuente de la artroplastia total de cadera (ATC). Sólo existen tres casos en la literatura. Ninguno de ellos informa del desmontaje de los componentes de la prótesis. Presentamos el caso una mujer obesa que sufrió una luxación irreducible de una artroplastia total de cadera (THA), la cual estaba infectada, debido a la aducción no controlada durante una cirugía de desbridamiento temprano. Después de los intentos fallidos de reducción cerrada, se presentó una fractura periprotésica clasificada como Vancouver B2 y el desmontaje de los componentes protésicos. Ameritó cirugía de revisión en dos etapas, lo cual se realizó para resolver la infección y restaurar la funcionalidad de la cadera. En la luxación obturatriz, la cabeza femoral puede quedar atrapada en el agujero obturador y, como consecuencia, favorecer la disociación de los componentes protésicos al intentar la reducción, asimismo puede favorecer un brazo de palanca que produzca una fractura periprotésica. La obesidad puede ser un factor determinante para la producción de esta rara complicación. Por todo lo anterior, se recomienda considerar de entrada la reducción abierta. La luxación obturatriz es una complicación rara en la artroplastia total de cadera; su tratamiento puede ser difícil y asociarse a fracturas. La relevancia de este caso es que permite mostrar algunas estrategias de manejo para prevenir complicaciones catastróficas.

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

ANTECEDENTES Y OBJETIVOS: Al menos el 10% de las fracturas de tobillo presentan afectación del maléolo posterior de la tibia, lo cual se ha relacionado con peor pronóstico a largo plazo. Nuestro objetivo ha sido analizar los resultados clínico-funcionales de las fracturas de tobillo con afectación del canto posterior, tratadas de forma quirúrgica sin reducción directa del tercer maléolo. MATERIAL Y MÉTODOS: Realizamos un estudio retrospectivo sobre 45 pacientes menores de 60años que hemos clasificado en tres grupos atendiendo al porcentaje de afectación articular del fragmento posterior (<10%, 10-25% y >25%), valorando los resultados funcionales mediante la escala visual analógica del dolor (EVA), la escala American Orthopaedic Foot and Ankle Society (AOFAS) de tobillo y retropié, y el cuestionario de salud global SF-36; también hemos analizado el grado de artrosis con radiografía en carga, al menos un año tras la lesión. RESULTADOS: La puntuación media del dolor EVA de la muestra fue de 1,1 (0-5) en reposo y de 3 (0-8) en ejercicio; en la escala AOFAS fue de 88,4+/-10,1 y en la de SF-36, de 68,5+/-19,3 puntos. Hasta el 18% de los pacientes desarrollaron artrosis radiográficamente significativa a corto y a medio plazo (entre 12 y 73 meses, con una media de 33 meses). El 55,6% presentaban una afectación entre el 10 y el 25% de la superficie articular. Comprobamos que un mayor tamaño del fragmento posterior se relacionaba con mayor grado de artrosis precoz (p < 0,03) y peores puntuaciones en la escala AOFAS (p < 0,01). CONCLUSIÓN: Las fracturas de tobillo con afectación del maléolo posterior parecen contribuir al desarrollo de artrosis precoz con limitación funcional en adultos jóvenes

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 73 months, with a mean of 33 months). 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
