ABSTRACT

Abstract Objective Our purpose was to facilitate the simulation of preoperative correction to enable shared doctor-patient decision-making in individuals undergoing high tibial osteotomy (HTO). Methods A total of 22 patients underwent high tibial osteotomy using internal or external fixation devices for medial compartment osteoarthritis of the knee. Preoperatively, assessment of deformity parameters and simulation of the corrective osteotomy was done in the presence of the patient, using Bone Ninja. Postoperatively, the patient's satisfaction level with the quality of explanation provided by the use of this software was assessed using the Patient Satisfaction Questionnaire-short (PSQ-18). A comparison of the correction obtained using paper cuttings and the simulation software was performed. Results All patients were satisfied with their role in the decision-making process. They showed a good understanding and comprehension of the proposed surgery. There was no statistically significant difference between simulated preoperative Medial Proximal Tibial Angle (MPTA) obtained by paper cuttings and software-assisted correction. The PSQ-18 mean score for communication was 4.24 (0.88), for technical quality it was 4.11 (0.59) and for general satisfaction it was 3.11 (0.68). Conclusion Bone Ninja is an effective, convenient, user-friendly and cost-effective deformity planning tool that supersedes the arduous traditional method of paper tracings and scissors.


Resumo Objetivo Nosso objetivo foi facilitar a simulação da correção no pré-operatório para permitir a tomada de decisão médico-paciente compartilhada em indivíduos submetidos a osteotomia tibial alta (OTA). Método22 pacientes foram submetidos a osteotomia tibial alta usando dispositivos de fixação internos ou externos para osteoartrite do compartimento medial do joelho. No pré-operatório, a avaliação dos parâmetros de deformidade e a simulação da osteotomia corretiva foram realizadas na presença do paciente, utilizando Bone Ninja. No pós-operatório, o nível de satisfação do paciente com a qualidade da explicação fornecida pelo uso deste software foi avaliado usando o Questionário de Satisfação do Paciente (Patient Satisfaction Questionnaire-short, PSQ-18, na sigla em inglês). Foi realizada uma comparação da correção obtida com recortes de papel e com o software de simulação. Resultados Todos os pacientes ficaram satisfeitos com seu papel no processo de tomada de decisão. Eles mostraram uma boa compreensão e entendimento da cirurgia proposta. Não houve diferença estatisticamente significativamente entre o ângulo tibial proximal medial (ATPM) pré-operatório simulado obtido por recortes de papel e correção assistida por software. O escore médio do PSQ-18 para comunicação foi de 4,24 (0,88), para a qualidade técnica foi de 4,11 (0,59) e para a satisfação geral foi de 3,11 (0,68). Conclusão Bone Ninja é uma ferramenta de planejamento de deformidade eficaz, conveniente, fácil de usar e econômica que substitui o método tradicional árduo de traçar no papel e com tesoura.

ABSTRACT

Abstract Objective The present study aimed to evaluate esthetic and functional outcomes from the surgical treatment of Madelung deformity in children. MethodThis is a retrospective study of pediatric patients with Madelung deformity who were surgically treated with dome osteotomy of the distal radius and Vickers ligament section from 2015 to 2018. Patients with a minimum postoperative follow-up period of 12 months were included. Demographic data, surgical technique, clinical and radiographic outcomes were analyzed. Pre and postoperative radiographic evaluation consisted of ulnar tilt, lunate subsidence lunate fossa angle, and palmar carpal displacement measurements. The postoperative clinical evaluation consisted of ranges of motion of the wrist, visual analog scale (VAS) and Disabilities of the Arm, Shoulder and Hand (DASH) score. Results Four patients were included, two with idiopathic Madelung deformity and two with bone dysplasia. All patients were females and presented bilateral disease. Six wrists were operated on. The median age at surgery was 15.5 years old, and the median postoperative follow-up time was of 37.5 months. The postoperative radiographic analysis revealed an average correction of 8.8 ± 7.5° for ulnar tilt, 3.0 ± 3.9 mm for lunate subsidence 8.2 ± 6.6° for lunate fossa angle, and 4.7 ± 2.6 mm for palmar carpal displacement. Average postoperative ranges of motion of the wrist joint were 75.8 ± 3.4° for flexion, 62.5 ± 14.1° for extension, 25.7 ± 2.9° for radial deviation, 40.0 ± 2.9° for ulnar deviation, 88.3 ± 2.4° for pronation, and 82.5 ± 2.5° for supination. The median VAS was 1 for residual pain, 0 for functional deficit, 0 for esthetic impairment, and 10 for recommending the surgical procedure. The median DASH score was 0. Conclusion Madelung deformity treatment using dome osteotomy of the distal radius and Vickers ligament section results in excellent esthetic and functional outcomes.

ABSTRACT

Abstract Objective The primary aim of the present study was to evaluate the long-term outcomes including survivorship of computer navigated distal femoral lateral opening wedge osteotomy (DFLOWO). The secondary aim was to identify the potential factors that may influence its survivorship. Methods A retrospective analysis of prospectively collected data for patients with lateral compartment arthritis who underwent navigated DFLOWO from December 2006 to November 2012 was performed. The International Knee Documentation Committee (IKDC) and Knee Injury and Osteoarthritis Outcome Score (KOOS) scores were analyzed for outcome measures. Conversion to arthroplasty during the follow-up was the end point. Results A total of 19 DFLOWOs were performed in 17 patients with a mean age of 46.6 ± 6.5 years formed the study cohort. The coronal alignment was corrected from a mean of 7.1° (2-11°) valgus to a mean of 2.1° (0.5°-3°) varus. The IKDC scores improved from mean of 39 preoperatively to 53 at the mean long-term follow-up of 9.1 years. The mean KOOS scores at the long-term follow-up were pain 71, symptoms 56, activities of daily living 82, sports and recreation 59, quality of life 43. Survivorship of the DFLOWO was 78.9% at a follow-up of 9.1 years. Presence of ≥ grade 2 according to the International Cartilage Repair Society (ICRS) cartilage degeneration in the medial compartment of the knee and >7° preoperative valgus deformity were strongly correlated with conversion to total knee arthroplasty (TKA) at the long-term follow-up (r= 0.66). ConclusionsComputer navigated DFLOWO has satisfactory clinical outcomes and 79% survivorship in long-term follow-up. Presence of more than ICRS ≥ grade 2 degenerative changes in the medial compartment of knee with > 7° preoperative valgus deformity negatively affects the survivorship of DFLOWO in the long-term follow-up.

ABSTRACT

Objetivos: Demostrar la utilidad y la facilidad técnica del injerto tibial en defectos óseos orales y maxilofaciales, para tenerlo como un recurso alternativo en la práctica general del cirujano oral y maxilofacial. Caso clínico: Se presenta un caso clínico con el uso de injerto óseo autólogo de tibia para el relleno de un defecto óseo a raíz de una lesión quística. Se realizó la exéresis de la patología quística por medio de un abordaje oral y posteriormente se recolectó hueso medular tibial a través de un abordaje medio al tubérculo anterior de la tibia, para poder colocarlo en el defecto óseo. Conclusión: El injerto de hueso medular de epífisis tibial representa un sitio de recolección de fácil acceso, del que se puede obtener una cantidad de hueso ideal para defectos de pequeño y mediano tamaño de la región maxilofacial, de baja morbilidad y con muy pocas complicaciones post-operatorias, lo que lo convierte en una alternativa para rellenos de cavidades óseas de gran utilidad (AU)


Objective: To demonstrate the utility and technical ease of the tibial graft in oral and maxillofacial bone defects so as to have it as an alternative resource in the general practice of the oral and maxillofacial surgeon. Case report: A clinical case is shown with the use of an autologous tibial bone graft to fill a bone defect as a result of a cystic lesion. The cyst was excised by an oral approach and the medial tibial bone was collected through a middle approach to the anterior tubercle of the tibia, to place it in the bone defect. Conclusion: The tibial epiphysis medullary bone graft represents an easily accessible collection site, from which an ideal amount of bone can be obtained for small and mediumsized defects of the maxillofacial region, with low morbidity and very few post-operative complications, which makes it a useful option for bone cavity filling (AU)

ABSTRACT

El acortamiento y la rotación del peroné son las deformidades más frecuentemente encontradas cuando se presentan maluniones postraumáticas del tobillo resultando en ensanchamiento de la mortaja e inestabilidad astragalina, con consecuentes cambios artrósicos. Los pacientes acuden por presentar dolor y limitación en sus actividades diarias y deportivas. En el presente estudio retrospectivo se hace una evaluación de los resultados clínicos y radiológicos de 9 pacientes que se sometieron a tratamiento quirúrgico posterior a maluniones de fracturas de peroné, en los cuales se realizaron osteotomías de alargamiento y desrotación para reconstrucción del tobillo, en la Unidad de Cirugía de Pie y Tobillo del Hospital Universitario de Caracas, entre junio de 2014 y agosto del 2019. Se realizaron mediciones radiológicas pre y postoperatorias de los ángulos de inclinación astragalina, talocrural y bimaleolar, y se reportaron los cambios degenerativos articulares. Para la evaluación clínica y funcional se aplicó la Escala Análoga Visual (VAS) para el dolor, y la Escala AOFAS de retropié, evidenciándose mejoría en cuanto a dolor, función y alineación. El objetivo del tratamiento fue restituir la longitud inicial del peroné, mediante osteototomías oblicuas en el sitio de la fractura anterior, o transversas suprasindesmales, con lo cual también se corrige la alineación del astrágalo, y de esta manera prevenir o disminuir los síntomas y signos inherentes a degeneración articular progresiva(AU)


The shortening and rotation of the fibula are the most frequent deformities found when post-traumatic ankle malunions occur, resulting in widening of the mortise and talus instability, with consequent arthritic changes. Patients have pain and limitation in their daily activities and sports. In the present retrospective study, an evaluation of the clinical and radiological results of 9 patients who underwent surgical treatment after fibular fracture malunions was performed, in which osteotomies of lengthening and de-rotation were performed for reconstruction of the ankle, in the Unit of Foot and Ankle Surgery at the University Hospital of Caracas, between June 2014 and August 2019. Pre and postoperative radiological measurements of the astragaline, talocrural and bimaleolar inclination angles were performed, and degenerative joint changes were reported. For the clinical and functional evaluation, the Visual Analog Scale (VAS) was applied for pain, and the AOFAS Hindfoot Scale, evidencing improvement in pain, function, and alignment. The objective of the treatment was to restore the initial length of the fibula by means of oblique osteotomies at the site of the previous fracture or suprasindesmal transverse osteotomy, which also corrects the alignment of the talus and thus prevents or decreases the symptoms and signs inherent to joint progressive degeneration(AU)

ABSTRACT

Abstract Distal radial fractures are very common. Vicious consolidation can occur in up to one third of these fractures, resulting in wrist pain, restricted movement, and, eventually, physical limitation or disability. The treatment of this condition consists in corrective osteotomy, which requires careful preoperative planning due to its three-dimensional complexity, especially in injuries with joint involvement. Recently, prototyping based on three-dimensional (3D) reconstruction of computed tomography (CT) scans has been used for osteotomy planning in a 3D anatomical model. It allows a better understanding of the deformity in a realistic surgical approach, leading to safer, faster, and more predictable procedures. The aim of the present study is to present this technique and show its use in two clinical cases.


Resumo As fraturas da porção distal do rádio estão entre as mais comuns do esqueleto. A consolidação viciosa pode ocorrer em até um terço dessas fraturas e acarretar restrição de movimento e dor no punho, com consequente limitação ou incapacidade laboral. O tratamento desta condição implica em osteotomia corretiva das deformidades, o que necessita de um planejamento pré-operatório criterioso em virtude de sua complexidade tridimensional, notadamente naquelas em que há acometimento articular. Assim, recentemente, tem sido utilizada a prototipagem a partir da reconstrução 3D da tomografia computadorizada (TC), o que permite o planejamento com realização da osteotomia em modelo anatômico tridimensional, com o melhor entendimento da deformidade, aproximando-se da situação realística da cirurgia, o que torna o procedimento mais seguro, ágil e previsível. O objetivo do presente estudo é apresentar esta técnica e seu emprego em dois casos clínicos.

ABSTRACT

Abstract Objective The present paper evaluates the resuming of physical activities by young, active patients who practiced some sport modality and underwent a high tibial osteotomy (HTO) using the opening wedge technique. Methods A total of 12 patients submitted to HTO using the opening wedge technique were prospectively analyzed. All patients were not playing sports at that time. Pre- and postoperative Lysholm and International Knee Documentation Committee (IKDC) scores, visual analog scale for pain and performance level were compared. The average follow-up time was of 12 months. Results One patient resumed sporting activities at a performance level significantly lower compared to the preoperative level, while eight patients returned at a slightly below level, two returned at the same level and one patient returned at a higher level in comparison with the preoperative period. Conclusion For isolated medial osteoarthrosis treatment, HTO using the opening wedge technique has favorable clinical and functional results, allowing patients to resume their sporting activities.

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 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

ABSTRACT Objective: To evaluate the clinical and radiological results of posterior vertebral column resection (PVCR) for the treatment of kyphosis from spinal tuberculosis. Methods: Retrospective study of a series of 14 cases, 9 female and 5 male, with a mean age of 28 years (1 to 64) at the time of surgery, with spinal tuberculosis with mean kyphosis of 56.42° (2° to 95°). Results: All patients underwent surgical treatment with PVCR, with a mean number of 2.57 (1 to 6) resected vertebrae and a mean number of instrumented vertebrae of 6.14 (4 to 8). The mean kyphosis correction was 64% after up to one year of follow-up. Prior to surgery, eight patients had signs of spinal cord impairment (ASIA score ranging from A to D), and six did not present any deficit of strength or sensory function (ASIA E). There was no neurological worsening and everyone with deficits improved by at least one degree on the scale. In the postoperative follow-up, bone consolidation was observed in all patients, except one. Among the intra- and postoperative complications, pleurotomy was the most prevalent. Conclusion: Posterior vertebral column resection has proven to be a safe and effective option for the treatment of kyphotic deformity from spinal tuberculosis. Level of evidence IV; Therapeutic studies - Investigation of treatment results.

ABSTRACT

Tibial plateau leveling osteotomy (TPLO) associated to cranial wedge closing ostectomy (CCWO) has been one of the best options to manage cranial cruciate ligament (CCL) disease and excessive tibial plateau angle (TPA) in large dogs, however, the complication rate is potentially high. It is believed that a more robust fixation is necessary to stabilize them and decrease the risk of implant failure. A 6-year-old male American Pit Bull, weighing 36kg, with 90-day history of right hind limb lameness, was diagnosed with CCL disease. Due to the excessive tibial plateau angle (42°), TPLO was associated with a modified CCWO using a double plating technique. A final TPA of 12° was accomplished, and a restricted level of exercises and physiotherapy were recommended. The patient was followed monthly until the fifth month postoperatively, when radiographic bone consolidation and no lameness were observed. By the date of this submission, 3 years after the procedure, the owner has reported no complications. The double plating technique for fixing TPLO and modified CCWO proved to be effective for the treatment of CrCL deficiency in a large dog with an excessive TPA.(AU)


A osteotomia de nivelamento do platô tibial (TPLO) associada à ostectomia modificada em cunha de fechamento cranial da tíbia (CCWO) tem sido uma das melhores opções para tratamento de cães grandes com doença do ligamento cruzado cranial (DLCCr) e ângulo excessivo do platô tibial, mas o índice de complicações é alto. Acredita-se haver necessidade de fixação mais robusta para reduzir as chances de falha nos implantes. Um cão macho, seis anos, da raça American Pit Bull, 36kg, com histórico de claudicação em membro pélvico direito há 90 dias, foi diagnosticado com DLCCr. Devido ao ângulo excessivo do platô tibial (42°), a osteotomia de nivelamento do platô tibial foi associada à ostectomia modificada em cunha de fechamento cranial da tíbia (CCWO) por meio da técnica de placa dupla. No pós-operatório imediato, identificou-se TPA de 12°; exercícios controlados e fisioterapia foram recomendados e a evolução do quadro foi analisada mensalmente até o quinto mês pós-cirurgia. Com 150 dias de evolução, não houve alterações de locomoção e havia ocorrido completa consolidação radiográfica das osteotomias. Até o momento da submissão deste artigo, três anos pós-procedimento, o tutor relata ausência de complicações, via contato telefônico. Portanto, a técnica modificada mostrou-se eficaz no tratamento da DLCCr.(AU)

ABSTRACT

La microcirugía endodóntica (MCE) es una alternativa al tratamiento no quirúrgico de la periodontitis apical persistente. Por su evolución junto a los avances tecnológicos, la incorporación de la tomografía computarizada de haz cónico (CBCT), la tecnología de impresión tridimensional (3D) y las guías quirúrgicas diseñadas con software asistido por computadora, han permitido implementar la planificación digital llevada a cabo en el acto quirúrgico. El objetivo de este informe es describir un caso clínico de MCE guiada, con un protocolo de diseño digital y el uso de una guía quirúrgica impresa en resina biocompatible, diseñada con precisión de acuerdo con las mediciones de CBCT preoperatorias. Se diseñó un kit de trefinas con "sleeves" (Neokings) para realizar la osteotomía y resección de los últimos 3 mm apicales direccionados por la guía quirúrgica. La tabla cortical intacta se recuperó y se utilizó como injerto junto con plasma rico en fibrina. La guía de cirugía apical permite al profesional lograr ubicar con precisión los tejidos objetivos de la cirugía y acortar el tiempo del procedimiento. Un control CBCT inmediato mostró la planificación exacta en 3D del sitio quirúrgico (AU)

ABSTRACT

Introducción: Existen múltiples tratamientos quirúrgicos del hallux valgus. El propósito de este estudio fue comparar los resultados radiográficos de corrección angular y su mantenimiento a mediano plazo, entre dos técnicas percutáneas: MICA y Bösch. Materiales y Métodos: Análisis prospectivo comparativo de pacientes sometidos a cirugía de hallux valgus mediante dos técnicas percutáneas (grupo Bösch: 42 pies, grupo MICA: 36 pies). Se compararon las correcciones de los ángulos IM, MTF y AMD, y el poder de corrección de ambas osteotomías y su mantenimiento a mediano plazo. Se registraron las complicaciones posoperatorias. Seguimiento mínimo: 6 meses. Resultados: La corrección promedio de los ángulos IM, MTF y AMD fue: 20,22°; 7,74°; 8,26° a los 6 meses en el grupo Bösch; y de 15,8°; 1,6° y 1,98° en el grupo MICA. El potencial de corrección IM fue mayor en el grupo Bösch. No hubo diferencias significativas entre ambos grupos en cuanto a la pérdida de corrección entre las 6 semanas y los 6 meses, salvo el ángulo MTF en el grupo MICA. La corrección del ángulo AMD fue mejor en el tiempo con la técnica MICA. Hubo 4 complicaciones con la técnica MICA y 8 con la técnica de Bösch. Conclusiones: Ambas técnicas logran una corrección adecuada del hallux valgus moderado. Sin embargo, el poder de corrección del ángulo IM a mediano plazo fue mayor con la técnica de Bösch. En el otro grupo, aunque se perdió la corrección del ángulo MTF entre las 6 semanas y los 6 meses, los valores se mantuvieron dentro de los 20° de valgo MTF. Nivel de Evidencia: II


Introduction: Multiple surgical treatments for the hallux valgus have been described. The purpose of this study is to compare the radiological results for the angular correction and its stability on the middle term between two percutaneous techniques (MICA versus BOSCH technique). Materials and methods: Prospective comparative analysis of surgically treated patients with hallux valgus by two percutaneous techniques (BOSCH group: 42 feet; MICA group: 36 feet) in homogenous groups. Intermetatarsal, metatarsophalangeal and distal metatarsal articular angle corrections were compared, as well as the correction power of both osteotomies and its stability in the middle term. Postoperative complications were recorded. Minimum follow-up: 6 months. Results: Average angle correction of MTP, IM y DMAA 6 months after surgery in Bosch group: 20,22°; 7,74°; 8,26°; MICA: 15,8°; 1,6° and 1,98° respectively. BOSCH group had a higher IM correction power. There were no significant statistical differences between both groups in the loss of correction by 6 weeks to 6 months; except for the MTP angle in the MICA group. MICA presented a better correction of the DMAA in time. Postoperatively, MICA had 4 complications, while BOSCH 8. Conclusions: We obtained good results with both techniques in the treatment of moderate hallux valgus. However, patients undergoing the Bosch technique had greater correction on the intermetatarsal angle in the mid-term follow-up. Although the MTP angle correction decreased between 6 weeksand 6 months in MICA technique, the values remained within normal 20° of valgus MTP. Level of Evidence: II

ABSTRACT

Introducción: Las técnicas para corregir las deformidades del hallux incluyen osteotomías metatarsianas y falángicas. Las osteo-tomías sobre la falange proximal corrigen el DASA y el ángulo interfalángico. Sin embargo, no se han publicado las indicaciones para la osteotomía de la falange distal. El objetivo de este artículo es comunicar la técnica y las indicaciones de la osteotomía percutánea de la falange distal del hallux, y evaluar los resultados de una serie de casos. materiales y métodos: Se analizaron 14 pies en los que se realizó una osteotomía de la falange distal del hallux para corregir una deformidad. Se midieron el DASA, la oblicuidad interfalángica y el ángulo falange distal-interfalángico en las radiografías. La técnica quirúrgica fue percutánea con control fluoroscópico. Los resultados se evaluaron mediante las escalas analógica visual de dolor y AOFAS. Seguimiento medio: 52 meses. Resultados: 13 pies de mujeres y un pie de hombre. Edad promedio: 58 años. Los resultados clínico y estético fueron excelentes, con alivio del dolor. Mejoría de la escala AOFAS: promedio 37 puntos. Análisis comparativo de ángulos preoperatorios y posoperatorios: DASA (p = 0,01), excepto cuando se aisló de la muestra a los pacientes con osteotomía tipo Akin (p = 0,33); ángulos F2-IF y F2-MTF (p <0,00001). Se registraron las complicaciones. Conclusiones: En la deformidad en valgo de la falange distal del hallux sintomática, se debe considerar una osteotomía correctora sola o asociada a osteotomía de la falange proximal. La osteotomía percutánea de la falange distal es un método eficaz, seguro y rápido. Nivel de Evidencia: IV


Introduction. There are many techniques to correct the hallux deformity. Most of them include metatarsal and/or phalanx osteotomies. The Akin osteotomy of the proximal phalanx is used to correct the distal articular set angle (DASA), or the interphalangeal angle. However, indications for the distal phalanx osteotomy remain unpublished. The aim of this study is to communicate the technique of performing and the indications for percutaneous osteotomy of the distal phalanx of the hallux, and evaluate the results of a cases series. Materials and methods. We report 14 cases in which distal phalangeal osteotomy was performed. Radiographic measurements were performed on dorsal-plantar view foot, to analyze distal articular set angle (DASA), interphalangeal obliquity, and F2-IP angle. Surgical technique was performed by minimally incision surgery. The clinical and functional results were evaluate by the visual analogue scale pain, and the AOFAS score. Mean follow-up was 52 months. Results. The clinical result for all the patients was excellent, pain was relieved and deformities corrected. Pre- and post-operative comparative angles: DASA (p: 0.01), except when isolated from the sample for Akin-type osteotomy (p: 0.33). Angle F2-IF and angle F2-MTF (p: <0.00001). The patients where highly satisfied with both the aesthetic and functional results. Complications were registered. Conclusion. In the symptomatic hallux´s distal phalanx deformity a corrective distal phalanx osteotomy should be considered alone, or associated with the osteotomy of the proximal phalanx. Percutaneous distal phalanx osteotomy is an effective, safe, and fast procedure. Level of Evidence: IV

ABSTRACT

Objetivo: Comunicar los resultados de una serie de adultos con consolidaciones en valgo del codo tratados con una osteotomía en cuña sustractiva monoplanar. materiales y métodos: Se incluyeron 5 pacientes. Se describe la técnica quirúrgica que consistió en un abordaje posterior paratricipital, resección en cuña sustractiva y transposición anterior del nervio cubital. El seguimiento promedio fue de 17 meses. Resultados: Se trató a 4 hombres y una mujer, con una edad promedio de 27 años. La movilidad preoperatoria promedio fue de 138-7° y la posoperatoria, de 138-6°, el puntaje de dolor en la EAV fue de 4 y 1, el MEPS de 71 y 97, y el DASH de 26 y 8, respectivamente. La evaluación radiográfica preoperatoria arrojó un valgo promedio de 30° con un valgo contralateral de 11°. La corrección radiográfica demostró un valgo de 13°. Se obtuvo una corrección promedio de 2° menos que del otro lado. Todas las osteotomías consolidaron, y la medición de la prominencia medial fue, en promedio, un 32% mayor que en el preoperatorio. Según la escala de Oppenheim, el resultado fue excelente en 4 pacientes y bueno en uno. La satisfacción personal fue, en promedio, de 8,6. Conclusiones: La osteotomía en cuña sustractiva para tratar un codo valgo es una buena opción terapéutica, con recuperación de valores angulares comparables con el lado contralateral, y alta tasa de satisfacción de los pacientes. Como es una técnica menos compleja que las osteotomías multiplanares, es nuestra elección ante una consolidación viciosa en valgo del codo del adulto. Nivel de Evidencia: IV


Objective: To report the results of a series of adult patients with a valgus malunion of the elbow treated with a supracondylar subtractive monoplanar wedge osteotomy, materials and methods: 5 patients were included. The surgical technique consisted of a posterior paratricipital approach, with resection of a subtractive wedge and the anterior transposition of the ulnar nerve. The average follow-up was 17 months.Results: 4 patients were men and 1 woman with an average age of 27 years. The preoperative range of motion was 138°-7° and the postoperative range of motion was 138-6°. Pain according to VAS was 4 and 1, MEPS was 71 and 97, and DASH was 26 and 8, respectively. The preoperative radiological evaluation showed an average valgus of 30° with a contralateral valgus of 11º. The final valgus obtained was 13°. The final correction was, on average, 2° less than the contralateral side. All osteotomies healed and the medial prominence was on average 32%, more than before surgery. According to Oppenheim scale, the results were excellent in 4 patients and good in 1. Personal satisfaction was, on average, 8.6. Conclusions: Supracondylar subtractive wedge osteotomy is a good option for the treatment of adult cubitus valgus with a recovery of angular values similar to the contralateral side and a high satisfaction rate. As it is a simpler technique, compared to the multiplanar osteotomies, it is our treatment of choice for adult cubitus valgus. Level of Evidence: IV

ABSTRACT

El objetivo de este artículo es actualizar los conocimientos sobre la impactación cubitocarpiana y su tratamiento. Estudios clásicos sobre la biomecánica del borde cubital de la muñeca han demostrado que los cambios milimétricos en la relación de longitud entre el cúbito y el radio alteran significativamente la transferencia de cargas entre los huesos del carpo, el radio y el cúbito. Así, un aumento relativo en la longitud del cúbito generará una carga excesiva sobre la articulación cubitocarpiana que producirá un espectro de cambios degenerativos progresivos en el domo cubital, el semilunar, el piramidal y el complejo del fibrocartílago triangular que finalizarán con artrosis cubitocarpiana y radiocubital distal. La impactación cubitocarpiana, en sus diversos estadios degenerativos, se puede tratar mediante osteotomías que buscan descomprimir la carga cubitocarpiana. Las osteotomías pueden ser extrarticulares o intrarticulares. Entre las extrarticulares, están las diafisarias, las metafisarias sin exposición articular (subcapitales) y las metafisarias distales con exposición articular y, entre las intrarticulares, la cirugía de resección en oblea (wafer), que reseca cartílago y hueso subcondral del domo cubital, y puede ser un procedimiento abierto o artroscópico. Si hay artrosis radiocubital distal, solo se podrá tratar con cirugías de rescate, como Darrach, Sauvé-Kapandji, Bowers, o una prótesis radiocubital distal. Estas técnicas de osteotomía se han analizado detalladamente para lograr definir sus ventajas y desventajas. Finalmente se propone una forma de tipificar la impactación cubitocarpiana, cuyo objetivo es orientar al lector hacia el mejor tratamiento posible, avalado por la bibliografía actual. Nivel de Evidencia: V


The purpose of this article is to provide updated knowledge about ulnocarpal impaction syndrome (UCIS) and its treatment. Classic studies on biomechanics of the ulnar side of the wrist have shown that millimetrical changes in the relative lengths of the ulna and the radius significantly alter the load transmission between the carpal bones, the radius and the ulna. Thus, an increase in the relative length of the ulna will generate an excessive load on the ulnocarpal joint, which will produce a spectrum of progressive degenerative changes in the ulnar dome, lunate, triquetrum, and the triangular fibrocartilage complex (TFCC), that will lead to ulnocarpal and distal radioulnar joint (DRUJ) osteoarthritis. In its various degenerative stages, UCIS can be treated with osteotomies that seek to decompress the ulnocarpal load. These can be extra-articular or intra-articular. Within the extra-articular osteotomies, we find the diaphyseal, metaphyseal without joint exposure (subcapital), and the distal metaphyseal with joint exposure. Within the intra-articular ones, we find the wafer procedure, which resects the cartilage and subchondral bone of the ulnar dome, and can be performed either openly or arthroscopically. If there is associated DRUJ osteoarthritis, it can only be treated with salvage surgeries such as the Darrach, Sauvé-Kapandji, and Bowers procedures, or a DRUJ arthroplasty. These osteotomy techniques will be analyzed in detail in order to define their advantages and disadvantages. Finally, we propose a way to typify the UCIS to guide the reader towards the best possible treatment supported by current literature. Level of Evidence: V

ABSTRACT

Introducción: El reemplazo total de rodilla luego de una osteotomía tibial alta plantea dificultades técnicas adicionales. El objetivo de este estudio fue analizar los resultados clínicos y radiográficos de la conversión a reemplazo total de rodilla luego de una osteotomía tibial alta y comparar la evolución de los pacientes con una osteotomía de cierre (sustractiva) o de apertura (aditiva) previa. Materiales y Métodos: Se analizó retrospectivamente una serie de 46 artroplastias de rodilla realizadas entre 1997 y 2019, en 39 pacientes con antecedente de osteotomía tibial alta. Se evaluaron los parámetros clínicos y radiográficos antes de la artroplastia y después, determinando el eje femorotibial, la caída tibial posterior, el valor de Insall-Salvati y el Knee Society Score. También se compararon los resultados en pacientes con antecedente de osteotomía tibial sustractiva vs. aditiva. Resultados:El seguimiento promedio fue de 5.72 años (mín. 1, máx. 19). El Knee Society Score de la serie tuvo una mejoría promedio de 42,3 a 79,8. La caída tibial posterior y el índice de Insall-Salvati no sufrieron grandes modificaciones luego de la cirugía. La supervivencia promedio de la osteotomía aditiva hasta la conversión a reemplazo total de rodilla fue de 5.5 años, mientras que la de la sustractiva, de 13.5 años.Conclusiones:Pese a la dificultad técnica que puede plantear, el reemplazo total de rodilla luego de una osteotomía tibial alta valguizante tuvo una buena evolución clínico-radiográfica a corto y mediano plazo, y el tipo de osteotomía no repercutió en los resultados luego de la artroplastia.

Introduction: Total knee replacement after a high tibial osteotomy presents additional technical difficulties. The objective of this study was to analyze the clinical and radiological outcomes of conversion to total knee replacement after a high tibial osteotomy and to compare the evolution of patients with a history of a closing (subtractive) versus opening (additive) osteotomy. Materials and Methods: A series of 46 knee arthroplasties performed between 1997 and 2019 in 39 patients with a history of a high tibial osteotomy was retrospectively analyzed. The clinical and radiographic parameters were evaluated before and after the arthroplasty by measuring the femorotibial axis, the posterior tibial slope, the Insall Salvati value, and the Knee Society Score. At the same time, the results were compared in patients with a history of subtractive versus additive tibial osteotomy. Results:In the series of 46 patients, an average follow-up of 5.72 years was achieved (minimum 1, maximum 19). The Knee Society Score for the entire series had an average improvement from 42.3 to 79.8 points. The posterior tibial slope and the IS value did not show great modifications after surgery. In this series, the average survival of additive osteotomy until conversion to total knee replacement was 5.5 years, while for the subtractive one it was 13.5 years. Conclusions:Despite the technical difficulty that it may present, total knee replacement after a valgus high tibial osteotomy presented a good clinical-radiological evolution in the short and medium term and the type of osteotomy did not affect the results obtained after arthroplasty.

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.

ABSTRACT

Forensic odontology is a specialty of dental sciences that deals with dental evidence in the interest of the justice system. The science of autopsy has been developing from the ancient times even before the popularization of general medicine. The objective of a medico-legal autopsy is to identify significant clues for an ongoing forensic investigation. However, in certain circumstances, it is difficult to conduct an oral examination owing to the anatomic location of the oral cavity. The onset of rigor mortis after death poses further complications. Thus, skillful and sequential dissections of the oral and para-oral structures are required to expose the dentition. Dental autopsy includes incisions and resection of the jaw for the detailed examination of the oral cavity. The procedure involves various modes of examination, including visual and radiographic, which help in human identification in forensic investigation. The present paper provides an overview of the various methods of dental autopsy.
