ABSTRACT

Abstract Objective Clinodactyly is a congenital hand deformity that is characterized by coronal angular deviation and may occur in thumbs or fingers. Surgical treatment is indicated for severe angulations. Among the described techniques, one of the options consists of bone alignment by wedge-shaped addition osteotomy of the anomalous phalanx. Such alignment maneuver creates a problem in skin cover, along with soft-tissue tension at the concave aspect of the deformity. Hence, some sort of skin flap is required for the adequate operative wound closure. We aim to demonstrate the aforementioned technique and to assess the results of bilobed flap in the treatment of hand clinodactyly. Methods Retrospective study conducted between January 2008 and January 2015. Five patients were included in the study, including nine operated digits. Surgical indication consisted of angular deviations ˃ 30o. Neither patients with thumb deformities nor those with deformities associated to syndromes were excluded from the study. We assessed the functional and cosmetic outcomes of the technique, as well as complications and the satisfaction rates of the family. Results All patients had satisfactory functional and cosmetic results, with a mean skin healing of 18.6 days. Among nine operated digits, only one of the patients presented vascular compromise at the distal portion of the first flap lobe, albeit without necrosis or the need for any additional procedure. Patients were followed up on a minimum of 12-month interval. No deformity recurred during the observation period. Conclusion Bilobed flap for the treatment of hand clinodactyly is a good option for skin cover after the osteotomy.


Resumo Objetivo A clinodactilia é uma deformidade congênita da mão, caracterizada por desvio angular coronal, podendo ocorrer em polegares ou dedos. O tratamento cirúrgico é indicado para angulações severas. Dentre as técnicas descritas, uma das opções consiste no alinhamento ósseo, através de osteotomia em cunha de adição da falange anômala. Essa manobra de alinhamento gera uma dificuldade de cobertura cutânea, juntamente com a tensão das partes moles no lado côncavo da deformidade. Sendo assim, algum tipo de retalho cutâneo é necessário para o fechamento adequado da ferida cirúrgica. Objetivamos demonstrar a técnica citada e avaliar os resultados do retalho bilobado no tratamento das clinodactilias da mão. Métodos Estudo retrospectivo entre janeiro de 2008 e janeiro de 2015. Foram incluídos cinco pacientes no estudo, nove dedos foram submetidos à cirurgia. Tiveram indicação cirúrgica os pacientes com desvios angulares nos dedos acima de 30 graus. Não foram excluídos do estudo os pacientes com deformidades no polegar, nem aqueles com deformidades associadas a síndromes. Foram avaliados os resultados funcionais e estéticos com o uso desta técnica, assim como as complicações e o grau de satisfação dos familiares. Resultados Todos os pacientes apresentaram resultados funcionais e estéticos satisfatórios, com cicatrização cutânea média de 18,6 dias. Entre os nove dedos submetidos à cirurgia, apenas um dos pacientes apresentou comprometimento vascular na porção distal do primeiro lobo do retalho, porém sem necrose ou necessidade de qualquer procedimento adicional. Os pacientes foram acompanhados durante um intervalo mínimo de 12 meses. Nenhuma deformidade ocorreu durante o período de observação. Conclusão O uso do retalho bilobado no tratamento das clinodactilias da mão é uma boa opção para cobertura cutânea após a realização de osteotomia.

ABSTRACT

El trasplante dentario autólogo se define como el po-sicionamiento de una pieza dentaria autóloga en un alvéolo post extracción o en un lecho formado qui-rúrgicamente. Actualmente, siguiendo los criterios de selección adecuados y una técnica quirúrgica mi-nuciosa, resulta una alternativa terapéutica ideal en ciertos pacientes. La gran variabilidad de implantes dentales y alternativas de injertos óseos han resuelto el problema de sustituir una pieza dentaria perdida. En los pacientes en crecimiento o con potencial de crecimiento residual del proceso alveolar, se pone en evidencia el inconveniente que puede representar la colocación de implantes, lo que hace necesario ree-valuar la conservación de dientes y la utilización de técnicas quirúrgicas clásicas. Las tasas de éxito de los autotrasplantes autólogos han aumentado con el tiempo, alcanzando cifras mayores al 90%. En el pre-sente artículo se reporta un caso clínico de autotras-plante dentario con planificación digital y una réplica tridimensional de la pieza a trasplantar (AU)


Autologous tooth transplantation is defined as the positioning of an autologous tooth in a post-extraction socket or in a surgically formed bed. Currently, following the appropriate selection criteria and a meticulous surgical technique, it is an ideal therapeutic alternative in certain patients. The great variability of dental implants and bone graft alternatives have solved the problem of replacing a lost tooth. In growing patients or with potential for residual growth of the alveolar process, the inconvenience that implant placement can represent is evident, which makes it necessary to reevaluate tooth conservation and the use of classic surgical techniques. The success rates of autologous autologous transplants have increased over time, reaching figures greater than 90%. This article reports a clinical case of dental autotransplantation with digital planning and a three-dimensional replica of the piece to be transplanted (AU)

ABSTRACT

Proximal tibiofibular instability is a rare condition for which treatment is poorly codified. A 21-year-old patient, a leisure sportswoman, presented a post-traumatic anterolateral instability of the proximal tibiofibular articulation without cartilage lesion. We propose an original surgical technique based on a review of the literature that combines an anatomical ligamentoplasty of the proximal tibiofibular joint and a proximal fibular diaphyseal osteotomy to reduce the distal tibiofibular mechanical stresses. This original technique allows a favorable evolution with recovery of professional and sports activities at 6 months.

ABSTRACT

OBJECTIVE@#To investigate the clinical effect of using lengthened trochanteric osteotomy wire fixation combined with autologous bone graft in patients undergoing revision total hip arthroplasty.@*METHODS@#From December 2010 to December 2018, 18 patients underwent revision of total hip arthroplasty with extended trochanteric osteotomy wire fixation and autogenous bone graft, including 8 males and 10 females with an average age of (78.89±3.32) years old ranging from 68 to 82 years. The time from the initial replacement to the revision was 9 to 22 (16.33±2.93) years. The patients were followed up regularly after operation. The healing time of osteotomy, the time of full weight-bearing activity, Harris score of hip joint and complications were recorded.@*RESULTS@#All 18 patients were followed up for 16 to 38 months with an average of (25.78±6.65) months. The incision length was 16 to 21 cm with an average of (18.89±1.32) cm; the operation time was 105 to 128 min with an average of (115.44±6.59) min, the bleeding volume was 240 to 285 ml with an average of (267.44±13.77) ml. The healing time of osteotomy was 12 to 18 weeks with an average of (15.61±1.75) weeks. Harris score of hip joint was (47.11±5.04) before operation, (76.39±3.85) during full weight-bearing activities, and (82.22±2.76) at the final follow-up(P<0.05). During the follow-up period, there were no complications such as limb shortening, infection, poor incision healing, prosthesis loosening and sinking, and periprosthetic fracture.@*CONCLUSION@#In revision total hip arthroplasty, the use of extended trochanteric osteotomy wire fixation combined with autologous bone graft can achieve satisfactory clinical results, but the surgeon needs to make a systematic plan for the pre-revision, intraoperative and postoperative recovery.

ABSTRACT

El manejo de la inestabilidad patelofemoral se basa en una adecuada evaluación de alteraciones anatómicas predisponentes. Patela alta es una de las causas más importantes de inestabilidad objetiva. La alteración biomecánica que ésta produce puede conducir a luxación patelar recurrente, dolor y cambios degenerativos focales. El examen físico es fundamental en la toma de decisiones. La evaluación imagenológica ha evolucionado desde métodos basados en radiografía hacia mediciones en resonancia magnética, que permiten una orientación más acabada de la relación existente entre la rótula y la tróclea femoral. El tratamiento se fundamenta en la corrección selectiva de los factores causales, donde la osteotomía de descenso de la tuberosidad anterior de la tibia y la reconstrucción del ligamento patelofemoral medial son herramientas que deben considerarse racionalmente. Este artículo realiza una revisión de la literatura, otorgando los fundamentos quirúrgicos que explican la importancia del tratamiento específico de patela alta en inestabilidad rotuliana.


Patellofemoral instability management is based on a thorough evaluation of predisposing anatomical factors. Patella alta is one of the utmost causes of objective instability. As a result, biomechanical disturbance can lead to recurrent patellar instability, pain, and focal degenerative changes. Physical examination is paramount in decision making. Imaging evaluation has evolved from X-rays based methods to magnetic resonance measurements, which allows a more accurate assessment of the patellotrochlear relationship. Treatment is based on a selective risk factors correction, where tibial tubercle distalization osteotomy and medial patellofemoral ligament reconstruction must be considered altogether. This article reviews the surgical rationale of patella alta treatment in patellofemoral instability.

ABSTRACT

Los dientes supernumerarios y la fusión dental son anomalías del desarrollo dental cuyas causas aún no se han dilucidado con certeza. El cuarto molar inferior, también denominado distomolar, es uno de los dientes supernumerarios con menor frecuencia de aparición clínica y su fusión con el tercer molar es una condición todavía menos común. A continuación, se reportan los casos clínicos de tres pacientes masculinos que presentaron fusión del tercer molar inferior derecho con un distomolar tratados mediante odontectomía (AU)


Supernumerary teeth and dental fusion are abnormalities of dental development whose causes have not yet been elucidated with certainty. The lower fourth molar, also called distomolar, is one of the supernumerary teeth with the least frequency of clinical appearance and its fusion with the third molar is an even less common condition. Next, the clinical cases of three male patients who presented fusion of the right lower third molar with a distomolar treated by odontectomy are reported (AU)

ABSTRACT

El desarrollo de teléfonos inteligentes ha creado nuevas oportunidades para incorporar la tecnología médica en la práctica clínica diaria. La medición intraoperatoria exacta de los grados necesarios de corrección es un desafío frecuente para el cirujano cuando realiza osteotomías desrotadoras. Por lo general, se utilizan clavijas divergentes colocadas proximal y distal a la osteotomía que, luego de la desrotación, deben quedar paralelas. Sin embargo, la medición de estos grados, en general, se hace por estimación visual, lo que suele ser poco preciso. El objetivo de este estudio es describir un detalle técnico que combina la aplicación de clavijas divergentes con la medición intraoperatoria mediante telefonía móvil para mejorar la precisión de las osteotomías desrotadoras. Nivel de Evidencia: V


Smartphone technology has created new opportunities to incorporate medical technology into daily clinical practice. Accurate intraoperative measurement of the desired derotation angle is a frequent challenge for the surgeon when performing derotational osteotomies. Divergent pins are commonly used proximal and distal to the osteotomy, which after derotation should remain parallel. However, the measurement of the derotation angle is usually performed by visual estimation, which could be unreliable. The aim of this study is to describe a technical detail that combines the application of divergent pins with intraoperative measurement by mobile phone to improve the accuracy of derotational osteotomies. Level of Evidence: V

ABSTRACT

PURPOSE To describe patient-reported outcomes, radiological results, and revision to total hip replacement in patients with hip dysplasia that underwent periacetabular osteotomy as isolated treatment or concomitant with hip arthroscopy. METHODS Case series study. Between 2014 and 2017, patients were included if they complained of hip pain and had a lateral center-edge angle ≤ of 20°. Exclusion criteria included an in-maturate skeleton, age of 40 or older, previous hip surgery, concomitant connective tissue related disease, and Tönnis osteoarthritis grade ≥ 1. All patients were studied before surgery with an anteroposterior pelvis radiograph, false-profile radiograph, and magnetic resonance imaging. Magnetic resonance imaging was used to assess intraarticular lesions, and if a labral or chondral injury was found, concomitant hip arthroscopy was performed. The non-parametric median test for paired data was used to compare radiological measures (anterior and lateral center-edge angle, Tönnis angle, and extrusion index) after and before surgery. Survival analysis was performed using revision to total hip arthroplasty as a failure. Kaplan Meier curve was estimated. The data were processed using Stata. RESULTS A total of 15 consecutive patients were included; 14 (93%) were female patients. The median follow-up was 3.5 years (range, 2 to 8 years). The median age was 20 (range 13 to 32). Lateral center-edge angle, Tönnis angle, and extrusion index correction achieved statistical significance. Seven patients (47%) underwent concomitant hip arthroscopy; three of them (47%) were bilateral (10 hips). The labrum was repaired in six cases (60%). Three patients (15%) required revision with hip arthroplasty, and no hip arthroscopy-related complications are reported in this series. CONCLUSION To perform a hip arthroscopy concomitant with periacetabular osteotomy did not affect the acetabular correction. Nowadays, due to a lack of conclusive evidence, a case by case decision seems more appropriate to design a comprehensive treatment.

ABSTRACT

La búsqueda por encontrar métodos para acortar la duración de los tratamientos de ortodoncia tiene un pasado reciente, un presente y un futuro. Las fuerzas ortodóncicas que se ejercen sobre la membrana periodontal producen movimientos dentarios por modificaciones histológicas y biomoleculares. El conocimiento de los procesos biológicos da lugar a implementar cambios para favorecer la aceleración de los procesos resortivos y neoformativos. El objetivo de esta publicación es hacer una breve síntesis de lo acontecido con este tema y exponer el procedimiento de las micro-osteoperforaciones (MOPs) como una opción complementaria al tratamiento de ortodoncia convencional. Aún no existe suficiente apoyo de ensayos clínicos en humanos para aseverar su éxito. Más aún, distintos autores publican conclusiones contradictorias. Es de esperar que, en breve, nuevas investigaciones contribuyan a respaldarlo o desestimarlo (AU)


The quest to find methods to shorten the duration of orthodontic treatments has a recent past, a present, and a future. Orthodontic forces exerted on the periodontal membrane produce tooth movements by histological and biomolecular modifications. Knowledge of biological processes results in changes to promote the acceleration of spring and neoformative processes. The objective of this publication is to make a brief synthesis of what happened with this topic and expose the micro-osteoperforations (MOPs) procedure as a complementary option to conventional orthodontic treatment. There is not yet enough support from human clinical trials to assert its success. Moreover, different authors publish conflicting conclusions. It is to be expected that, shortly, further investigations will help to support or dismiss it (AU)

ABSTRACT

Una de las causas de la evolución de la periodontitis es la formación de defectos óseos y pérdida de inserción clínica. Una manera de eliminar el defecto intraóseo y su bolsa periodontal es eliminar las paredes de hueso que componen el defecto para colocar el complejo dentogingival en una posición más apical. La cirugía ósea es un procedimiento periodontal resectivo que involucra la modificación del tejido óseo del soporte dental, la cual es una modalidad del tratamiento periodontal quirúrgico que puede utilizarse para eliminar eficazmente los defectos óseos periodontales para estabilizar la inserción periodontal. El objetivo del presente estudio es realizar una revisión de la literatura sobre las consideraciones actuales, técnicas y principios de la cirugía ósea resectiva en el paciente periodontalmente comprometido (AU)


One of the causes of the evolution of periodontitis is the formation of bone defects and loss of clinical attachment, where one way to eliminate the intraosseous defect and its periodontal pocket is to eliminate the bone walls that make up the defect to place the dentogingival complex in a more apical position. Bone surgery is periodontal surgery that involves the modification of the supporting bone tissue of the teeth, which is a modality of surgical treatment that can be used to effectively eliminate periodontal defects and stabilize the periodontal insertion. The aim of the present study is to conduct a literature review about the considerations, techniques and principles of resective bone surgery in the periodontally compromised patient (AU)

ABSTRACT

RESUMEN: Paredes sin instrumentar y con material obturador endodóntico residual pueden elevar la posibilidad de la falla adhesiva de postes de fibroresina. Las fresas de desobturación y conformación del espacio protésico poseen una sección circular, lo que dificulta una adecuada preparación y limpieza de las paredes de los conductos ovales. El objetivo del presente estudio fue evaluar la capacidad de limpieza ultrasónica del espacio protésico y cómo ésta influyó en la resistencia a la tracción de postes de fibroresina en conductos ovales. Se utilizaron 30 premolares con conducto ovalado divididos aleatoriamente en 3 grupos de estudio (n=10), siendo: grupo A: preparación rotatoria con complemento ultrasónico, grupo B: preparación rotatoria y grupo C: grupo control. Postes de fibra de vidrio fueron cementados y luego de 7 días se realizaron cortes de un milímetro de grosor del tercio cervical y medio de cada muestra y se evaluó microscópicamente el área de gutapercha remanente y área efectiva de adhesión. Estos fueron sometidos a una prueba de push out evaluando la resistencia adhesiva de los postes. Finalmente fueron observados microscópicamente para analizar tipo de falla. Los resultados se analizaron mediante el test de ANOVA, Bonferroni, Kruskal-Wallis y Mann Whitney (p < 0.05), registrando diferencias estadísticamente significativas en la resistencia a tracción, área de gutapercha remanente y área disponible para la adhesión; además de una relación directa entre gutapercha remanente y menor resistencia a la tracción. Conclusiones: La preparación ultrasónica del espacio protésico aumenta la resistencia a la tracción de postes de fibroresinas cementados en conductos ovalados.


ABSTRACT: Untouched canal walls with residual filling materials can increase the probability of adhesive failure of fiber posts. The drills used for desobturation and conformation of the prosthetic space, has a circular cross section, which does not allow a proper preparation and cleaning of oval-shaped canal walls. The objective of the study was to evaluate the ultrasonic cleaning of the prosthetic space and how this influences the adhesive strength of fiber posts in oval-shaped canals. Thirty (30) oval-shaped canal premolars were randomly divided into 3 groups (n = 10): Group A: rotary desobturation with ultrasonic complement, group B: rotary desobturation without ultrasonic complement and group C: control group. Fiberglass posts were cemented; after 7 days, one-millimeter slices were performed, one of the cervical and another from the middle third of the root. The slices were analyzed under an optical microscope to evaluate remaining gutta percha and effective adhesion area. Samples were subjected to a push-out test to evaluate bond strength of the fiber resin posts. Finally, samples were evaluated microscopically to analyze the type of failure. The results were analyzed using ANOVA, Bonferroni, KruskalWallis and Mann Whitney test (p < 0.05), recording statistically significant differences in bond strength, remaining gutta-percha area and clean walls for adhesion; In addition, to a direct relationship between remaining gutta percha and lower adhesive strength, the ultrasonic preparation of the prosthetic space increases bond strength of fiber posts in oval canals.

ABSTRACT

Pedicle subtraction osteotomy (PSO) is a powerful tool for themanagement of sagittal misalignment. However, this procedure has a high rate of implant failure, particularly rod breakages. The four-rod technique diminishes this complication in the lumbar spine. The aim of the present study is to provide a case report regarding PSO and fourrod technique stabilization in the treatment of short-angle hyperkyphosis in the thoracolumbar (TL) junction. The authors describe the case of a patient with TL hyperkyphosis secondary to spinal tuberculosis treated with L1 PSO and fixation with a four-rod technique. There were no major surgical complications. The self-reported quality of life questionnaires (the Short-Form Health Survey 36 [SF-36] and the Oswestry disability index) and radiological parameters were assessed preoperatively, as well as 6, 12 and 24 months after surgery, and they showed considerable and sustained improvements in pain control and quality of life. No hardware failure was observed at the two-year follow-up.

ABSTRACT

RESUMEN: Un desafío común en la ortodoncia es la realización de cierres de espacio en brechas largas con pérdida ósea significativa producto de extracciones tempranas, sitio de extracciones traumáticas o expansiones en adultos con tabla vestibular delgada. El propósito de este artículo es difundir una teoría del movimiento dental desarrollada a partir de una serie de investigaciones que intentan probarla en animales como seres humanos. Las dos fases de remodelación de hueso son la "activación - reabsorción" (proceso catabólico) y "activación-formación" (proceso anabólico) de las superficies del hueso, resultando en los cambios de tamaño, forma y posición del hueso. La inflamación es necesaria para el movimiento dentario. Se puede estimular ambas fases mediante pequeñas perforaciones del hueso que pueden ser realizadas de forma segura en la superficie vestibular o lingual de las tablas corticales pudiendo ser superficiales o profundas. Se muestran ejemplos clínicos de pacientes tratados con el enfoque de la Teoría bifásica mediante estimulación ósea transgingival. Se concluye que esta teoría bifásica permite explicar la favorable respuesta que se observa en situaciones clínicas complejas cuando se estimula el movimiento con micro-osteoperforaciones.


ABSTRACT: A common challenge in orthodontics is the task of space closures in long gaps with significant bone loss due to early extractions, site of traumatic extractions or expansions in adults with thin vestibular table. The purpose of this article is to disseminate a theory of dental movement developed from a series of investigations that try to test it in animals as human beings. The two phases of bone remodeling are the "activation - resorption" (catabolic process) and "activation-formation" (anabolic process) of bone surfaces, resulting in changes in bone size, shape and position. Inflammation is necessary for tooth movement. Both phases can be stimulated by small perforations of the bone that can be performed safely on the vestibular or lingual surface of the cortical boards, which may be superficial or deep. Clinical examples of patients treated with the biphasic theory approach by transgingival bone stimulation are shown. It is concluded that this biphasic theory allows to explain the favorable response observed in complex clinical situations when the movement is stimulated with micro-osteoperforations.

ABSTRACT

Introducción: El síndrome de pinzamiento cubito carpiano es una de las causas más frecuentes de dolor cubital de la muñeca. Es una patología de tipo degenerativa y progresiva. El objetivo del tratamiento quirúrgico se basa en la descompresión articular del cubito con el carpo proximal. Con los avances tecnológicos es posible realizar la osteotomía del cubito por via artroscópica y así tratar también lesiones asociadas. Material y Métodos: Evaluamos 13 pacientes con síndrome de impactación cubital desde el 01/01/2018 hasta el 01/03/19, utilizando la clasificación de Palmer para evaluar las lesiones. Evaluamos 7 mujeres y 6 hombres. La edad de los pacientes fue desde los 47-82 años (62 años promedio). El 69,2% en edad laboral (9 pacientes) y el 30,7% jubilados (4 pacientes) con un seguimiento de 3 a 12 meses (8,9 meses de promedio). Todos los pacientes fueron tratados por artroscopia. Se evaluó el Rango de Movilidad (ROM), fuerza de agarre, escala de Mayo de Muñeca y escala de DASH. Resultados: Hemos tenido mejoras en test del dolor y la fuerza, el ROM promedio fue de 80° extensión, 80° de flexión, 30° para la desviación radial y 25° de desviación cubital. El Score de muñeca de mayo fue: excelente 8 pacientes (61,5%), bueno en 5 pacientes (38,4%) y un mal resultado (7,69). La fuerza comparativa final fue del 82%. El Dash Score preoperatorio fue de 87 puntos y en el Post operatorio de 5 puntos. Conclusión: La osteotomía de cubito tipo wafer o en oblea artroscópica da resultados satisfactorios mejorando los ROM, recuperando la fuerza de forma total o parcial y disminuyendo el dolor siempre y cuando está bien indicada la cirugía. Tipo de estudio: Serie de casos. Nivel de evidencia: IV


Introduction: The ulnar carpal impingement syndrome is one of the most frequent causes of ulnar pain in the wrist. It is a pathology of degenerative and progressive type. The objective of surgical treatment is based on the joint decompression of the ulna with the proximal carpus. With technological advances, it is possible to perform the osteotomy of the ulna by arthroscopic route and thus also treat associated injuries. Material and Methods: We evaluated 13 patients with ulnar impaction syndrome from 01/01/2018 to 03/01/19 using the Palmer classification to evaluate the lesions. We evaluated seven women and six men. The age of the patients was from 47-82 years (62 years average). 69.2% of working age (9 patients) and 30.7% retired (4 patients) with a follow-up of 3 to 12 months (8.9 months on average). All patients were treated by arthroscopy. The Mobility Range (ROM), grip strength, Wrist May scale and DASH scale were evaluated. Results: We have had improvements in pain and strength tests, the average ROM was 80° extension, 80° flexion, 30° for radial deviation and 25° ulnar deviation. The Wrist Score of May was excellent 8 patients (61.5%), Good in 5 patients (38.4%) and a poor result (7.69). The final comparative strength was 82%. The preoperative Dash Score was 87 points and in the post-operative of 5 points. Conclusion: The osteotomy of ulnar type wafer or arthroscopic wafer gives satisfactory results improving the ROM, recovering the strength totally or partially and decreasing the pain as long as surgery is well indicated. Type of study: Case series. Level of evidence: IV

ABSTRACT

Introducción: La osteotomía de la tuberosidad anterior de la tibia (O-TAT) es una técnica quirúrgica que permite restablecer la alineación distal de la rótula en pacientes esqueléticamente maduros. Los objetivos de este estudio fueron evaluar los resultados funcionales y analizar factores que influyeron en el desarrollo de complicaciones. Materiales y Métodos: Se analizaron retrospectivamente pacientes con O-TAT tratados entre 2008 y 2016. Se documentaron datos demográficos y clínicos. Los resultados fueron evaluados según las escalas de Kujala y Tegner-Lysholm, y las complicaciones, con una adaptación de la clasificación de Clavien- Dindo. Resultados: Se analizaron 33 O-TAT en 29 pacientes (17 mujeres). Mediana de la edad: 18 años (RIC 2, mín.-máx. 14-39). Mediana de seguimiento: 49 meses (RIC 2, mín.-máx. 12-115). Mejoría en las escalas de Kujala y Tegner-Lysholm de 61 y 61,5 a 94 y 92,3, respectivamente (p = 0,001). La mediana de tiempo de consolidación fue de 8 semanas. Hubo 9 complicaciones (27%): 1 grado II (infección superficial) y 8 grado III (artrofibrosis, fracturas de tibia y fracturas de TAT, n = 2). La tasa de complicaciones fue más alta en los pacientes sometidos a desinserción de la TAT (51,5% vs. 11,1%, p = 0,029). Conclusiones: La O-TAT representa una técnica eficaz para tratar diversas patologías de la articulación patelofemoral en adolescentes y adultos jóvenes. Hubo complicaciones en un alto porcentaje de los procedimientos, sin que esto afectara el resultado final. El riesgo de complicaciones fue mayor en las osteotomías que requirieron desinserción de la TAT y la reconstrucción ligamentaria. Nivel de Evidencia: IV


Introduction: Tibial tubercle osteotomy (TTO) is a surgical approach that allows for the restoration of distal patellar alignment in skeletally mature patients. The objectives of this study were to evaluate functional results and to analyze the risk factors associated with complications. Methods: We carried out a retrospective analysis of patients subjected to a TTO between 2008 and 2016 and documented demographic and clinical data. Results were evaluated according to Kujala Anterior Knee Pain Scale and Tegner-Lysholm Knee Scoring Scale. Complications were evaluated with a modified Clavien-Dindo classification of Surgical Complications. Results: We evaluated 33 TTOs in 29 patients (17 women) with a median age of 18 years (IQR 2, range 14-39) and a median follow-up time of 49 months (IQR 2, range 12-115). The Kujala and the Tegner-Lysholm scoring improved from 61 and 61.5 to 94 and 92.3, respectively (p=0.001). Union was achieved at a median of 8 weeks. There were 9 complications (27%): a grade II complication (superficial infection) and 8 grade III complications (arthrofibrosis, tibial fractures, and anterior tibial tubercle fractures). Osteotomies in which tibial tubercle was completely detached had a significantly higher rate of complications (51.5% vs. 11.1%, p=0.029). Conclusions: TTO represents an effective approach for the treatment of several conditions of the patellofemoral joint in adolescents and young adults. In our series, a high percentage of the procedures presented complications, although they did not affect the final result. Osteotomies that involve complete detachment of the tubercle and those associated with ligament reconstruction have an increased risk of complications. Level of Evidence: IV

ABSTRACT

Introducción: La osteotomía de la tuberosidad anterior de la tibia es un procedimiento efectivo y seguro para el tratamiento de la inestabilidad patelofemoral. El objetivo del presente trabajo es desarrollar las indicaciones y evaluar las complicaciones de dicho procedimiento realizado en un grupo de pacientes intervenidos por nuestro equipo. Material y método: Se analizaron en forma retrospectiva las historias clínicas de 77 pacientes intervenidos quirúrgicamente por inestabilidad patelofemoral a quienes se les realizó una osteotomía de la TAT, y en quienes se utilizó la misma técnica quirúrgica. Se registró edad, sexo, actividad deportiva y número de intervenciones, y se analizaron las indicaciones quirúrgicas de cada caso. Por último, se cuantifico el número de complicaciones (menores y mayores) y se evaluó el grado de satisfacción postquirúrgica de los pacientes con el score de kujala. Resultados: En la mayoría de los casos los pacientes presentaban un aumento de la distancia ST-TAT de más de 20 mm con un ángulo Q aumentado, asociado a episodios de luxación recidivante de rotula y dolor anterior de rodilla. La complicación más frecuente fue la recidiva del dolor (de menor intensidad y frecuencia que el presentado previo a la cirugía). Registramos dos casos de aflojamiento de material que requirió una segunda cirugía y un caso de secreción persistente de herida quirúrgica que no requirió re intervención. Conclusión: La osteotomía de la TAT es una procedimiento eficaz y con bajo índice de complicaciones postoperatorias para tratar la luxación recidivante de rotula, permitiendo al paciente retornar a sus actividades deportivas con un bajo porcentaje de morbilidad postoperatoria. Tipo de estudio: Serie de casos. Nivel de evidencia: IV


Introduction: Tibial anterior tuberosity osteotomy is an effective and safe procedure for the treatment of patello-femoral instability. The objective of the present paper is to talk about the indications and to evaluate the complications of the mentioned procedure performed in a group of patients who underwent surgery with our team. Material and method: The clinical histories of 77 patients operated due to patello-femoral instability, who underwent TT osteotomy and in whom the same surgical technique was performed, were analyzed retrospectively. Age, gender, sports activity and number of surgeries were registered and surgery indications in each case were analyzed. Lastly, the number of (minor and major) complications was quantified and patients postop satisfaction was evaluated with the Kujala score. Results: In most of cases patients presented a ST-TT distance increase of over 20 mm with an augmented Q angle associated to patellar recurrent luxation episodes and to anterior knee pain. The most frequent complication was pain recurrence (of lower intensity and frequency than that presented prior to surgery). Two cases of loosening material which required a second surgery and one case of persistent secretion from the surgical wound which did not require a new surgery were registered. Conclusion: The TT osteotomy is an effective procedure and with a low postop complications rate to treat patellar recurrent luxation, which allows the patient to resume sports activities with a low rate of postop morbidity. Type study: Case series. Level of evidence: IV
