ABSTRACT

OBJECTIVE@#To investigate the short-term effectiveness of INBONE TM Ⅱ total ankle prosthesis arthroplasty in the treatment of moderate to severe varus-type ankle arthritis.@*METHODS@#The clinical and radiographic data of patients with moderate to severe varus-type ankle arthritis, who were admitted between May 2017 and November 2021 and treated with total ankle arthroplasty (TAA) using INBONE TM Ⅱ prosthesis, was retrospectively analyzed. A total of 58 patients (58 ankles) met the selection criteria and were included in the study. Among them, there were 24 males and 34 females, with an average age of 62.6 years (range, 41-85 years). According to the preoperative tibiotalar angle (TTA), the patients were divided into a moderate varus group (group A, TTA 5°-15°, n=34) and a severe varus group (group B, TTA>15°, n=24). There was no significant difference in gender, side, etiology, preoperative American Orthopaedic Foot and Ankle Society (AOFAS) score, ankle dorsiflexion, plantarflexion, and total range of motion, and tibial lateral surface angle (TLS) between the two groups ( P>0.05). Yet the patients in group A were younger than group B, the degrees of oesteoarthritis (Takakura stage) and ankle pain [visual analogue scale (VAS) score] were milder, and the TTA, talar tilt angle (TT), hindfoot alignment angle (HAA) were smaller while the tibial articular surface angle (TAS) was larger, showing significant differences ( P<0.05). The pre- and post-operative VAS score, AOFAS score, the occurrence of early and late complications, the radiographic parameters of the ankle (TTA, TAS, TT, HAA, TLS), ankle dorsiflexion, plantarflexion, and total range of motion were recorded and compared.@*RESULTS@#All patients were followed up 19-72 months, with an average of 38.9 months. Compared with the preoperative data, the VAS score of all patients significantly decreased ( P<0.05); the AOFAS score, ankle dorsiflexion range of motion, and total range of motion significantly increased ( P<0.05); and the TTA, TAS, TT, HAA, and TLS significantly improved at last follow-up ( P<0.05); but there was no significant difference in plantarflexion range of motion ( P>0.05). Early complications occurred in 13 patients, and only 1 patient underwent revision surgery due to a larger size of the talar component. At last follow-up, there was no significant difference in the difference of clinical parameters before and after operation between the two groups ( P>0.05); there was a significant difference in the difference of other radiographic parameters ( P<0.05) except TLS. No significant difference in the incidence of complications between the two groups was found ( P>0.05).@*CONCLUSION@#TAA using the INBONE TM Ⅱtotal ankle prosthesis is an effective treatment for moderate or severe varus-type ankle arthritis, and good clinical and radiographic results can be obtained. Correcting bony deformities and balancing soft tissue are the keys to successful surgery.

ABSTRACT

Ankle arthritis affects approximately 1% of the adult population worldwide and represents a serious global disease burden. However, compared with hip arthritis and knee arthritis, the clinical understanding and treatment of ankle arthritis are still in their infancy. For end-stage ankle arthritis, ankle arthrodesis was considered as the "gold standard" in the past. However, ankle arthrodesis will result in loss of joint mobility, altered gait, limited daily activities, and accelerated degeneration of adjacent joints. Therefore, how to preserve the range of motion of the ankle joint while relieving pain is the key to the treatment of ankle arthritis. Currently, the surgical treatment of ankle arthritis includes arthroscopic debridement, periarticular osteotomies, osteochondral transplantation, ankle distraction arthroplasty, ankle arthrodesis, and total ankle arthroplasty. The choice of treatment should be individualized and based on various factors such as the patient's symptoms, signs, imaging performance, complaints, and financial situation. However, there are no guidelines that give clear treatment recommendations. Therefore, it is necessary to conduct extensive and in-depth discussions on the diagnosis and treatment of ankle arthritis.

ABSTRACT

OBJECTIVES@#To summarize our experience with the sural neurofasciocutaneous flap for reconstructing the soft tissue defects over the forefoot distal to the connecting line of midpoints in the metatarsal bones, and to compare the outcomes between the flap for resurfacing the defects distal and proximal to the connecting line.@*METHODS@#The clinical data of 425 sural neurofasciocutaneous flaps for repairing the soft tissue defects in the middle and lower leg, ankle, and foot between Apr. 2002 and Apr. 2020 were reviewed. Based on the connecting line of midpoints of the metatarsals, the sural neurofasciocutaneous flaps were divided into a forefoot group (flaps with furthest edges distal to the connecting line) and a peri-ankle group (flaps with the furthest edges proximal to the connecting line).@*RESULTS@#The partial necrosis rate in the forefoot group (14.5%, 10/69) was significantly higher than that in the peri-ankle group (7.0%, 25/356), with significant difference (P<0.05). Using the flap alone or in combination with a simple salvage treatment, the ratio of successful coverages of the defects was 98.6% (68/69) in the forefoot group, and 97.8% (348/356) in the peri-ankle group, respectively, with no statistical difference (P>0.05).@*CONCLUSIONS@#The sural neurofasciocutaneous flap is a better choice for covering the soft tissue defects over the forefoot distal to the connecting line of midpoints of the metatarsal bones. The survival reliability of the sural neurofasciocutaneous flap reconstructing the soft tissue defect proximal to the connecting line is superior to that of the flap reconstructing the defect distal to the connecting line.

ABSTRACT

SUMMARY OBJECTIVE: The objective of this study is to report the results of arthroscopic debridement of the subtalar joint in eight patients with Sinus Tarsi Syndrome (STS) refractory to conservative treatment. METHODS: This is a retrospective study of eight patients with STS who underwent subtalar arthroscopy for debridement of the sinus tarsi between January 2015 and January 2017 after six months of conservative treatment. All patients answered an epidemiological questionnaire and underwent functional evaluation with the Visual Analogue Pain Scale (VAS) and the American Orthopedic Foot and Ankle Society Score (AOFAS) in the preoperative and in the last evaluation (average of 12 months - 6-24 months). RESULTS: All patients showed severe synovitis in the region. Seven patients had remnants of the talocalcaneal ligaments and six of the cervical ligament. AOFAS increased by 30 points on average (51.75 in the preoperative period to 82.62 in the last follow-up) and the VAS decreased on average by 5 points (7.37 preoperatively to 2.12 in the last follow-up). These results were statistically significant with p = 0.043 and p = 0.032 respectively. Six patients described the result as excellent and two as good. No complications were reported. All patients returned to sports after six months of follow-up. CONCLUSION: The arthroscopic debridement of the subtalar joint is an effective and safe alternative in the treatment of STS refractory to conservative treatment. More studies, with a prospective methodology, are necessary to prove the results of this technique.


RESUMO OBJETIVO: O objetivo desse estudo é relatar os resultados do desbridamento artroscópico da subtalar em oito pacientes portadores da Síndrome do Seio do Tarso (SST) refratária ao tratamento conservador. MÉTODOS: Este é um estudo retrospectivo com oito pacientes com diagnóstico de STT que foram submetidos à artroscopia subtalar para desbridamento do seio do tarso entre janeiro de 2015 e janeiro de 2017, após seis meses de tratamento conservador. Todos os pacientes responderam questionário epidemiológico e foram submetidos à avaliação funcional com a Escala Visual Analógica de dor (EVA) e o American Orthopaedic Foot and Ankle Society Score (Aofas) no pré-operatório e na última avaliação, em uma média de 12 meses (6-24 meses). RESULTADOS: Todos os pacientes exibiram intensa sinovite na região. Sete pacientes tinham resquícios de ligamentos talocalcaneanos e seis do ligamento cervical. O Aofas aumentou 30 pontos em média (51,75 no pré-operatório para 82,62 no último seguimento) e a EVA diminuiu em média 5 pontos (7,37 no pré-operatório para 2,12 no último seguimento). Esses resultados foram estatisticamente significativos com p = 0,043 e p = 0,032, respectivamente. Seis pacientes descreveram o resultado como excelente e dois como bom. Nenhuma complicação foi relatada. Todos os pacientes retornaram ao esporte após seis meses de acompanhamento. CONCLUSÃO: O desbridamento artroscópico da subtalar é uma alternativa eficaz e segura no tratamento da SST refratária ao tratamento conservador. Mais estudos, com metodologia prospectiva, são necessários para comprovar os resultados da técnica.

Conclusiones: el bloqueo del pie a nivel del tobillo con fines quirúrgicos, resulta eficaz en las lesiones del pie en pacientes diabéticos; ya que mejora la calidad de vida de estos al brindarles una técnica anestésica adecuada en manos eficientes(AU)


Introduction: the most feared complication of diabetes mellitus (DM) is the diabetic foot and, as a threatening consequence of this, the amputation of the whole limb, with all the psychological and social significance it brings. Ankle-level block, despite being a simple technique, is not standard practice for patients with impaired physical condition. Objectives: to identify the effectiveness of the ankle block for surgical procedures of the foot in diabetic patients with compromised physical condition. Methods: A longitudinal, observational, analytic, prospective, cohort study was carried out in a population of diabetic patients in Dr. Antonio Agostinho Neto General Teaching Hospital of Guantanamo, who were surgically intervened for infectious foot lesions and performed ankle-level foot-trunk block. From a sample group of 48 patients, through a probabilistic determination, a sample of 32 was taken during the period from February 2014 to February 2016. Results: There was a predominance of urgent interventions located on the instep and knuckles amputation. Complications were minimal as related to the application of the ankle block technique, with only one failure of the technique; adequate hemodynamic clinical control was maintained, 100 percent of postoperative analgesia was ensured. Conclusions: the ankle-level foot block for surgical purposes is effective in diabetic patients' foot lesions, as it improves their quality of life by providing adequate anesthetic technique in efficient hands(AU)

ABSTRACT

The main etiology of ankle osteoarthrosis is post-traumatic and its prevalence is highest amongyoung individuals. Thus, this disease has a great socioeconomic impact and gives rise to significant losses of patients' quality of life. The objective of its treatment is to eliminate pain and keep patients active. Therefore, the treatment should be staged according to the degree of degenerative evolution, etiology, joint location, systemic condition, bone quality, lower-limb alignment, ligament stability and age. The treatment algorithm is divided into non-surgical therapeutic methods and options for surgical treatment. Joint preservation, joint replacement and arthrodesis surgical procedures have precise indications. This article presents a review on this topic and a proposal for a treatment algorithm for this disease...


A principal etiologia da osteoartrose (OA) do tornozelo é pós-traumática e sua maior prevalência está entre indivíduos jovens; assim, essa doença apresenta grande impacto socioeconômico e significativo prejuízo na qualidade de vida dos pacientes. O objetivo do tratamento é eliminar a dor e manter os pacientes ativos. Dessa forma, o tratamento deve ser estagiado de acordo com o grau de evolução da degeneracão, a etiologia, a localização articular, a condição sistêmica, a qualidade óssea, o alinhamento do membro inferior, a estabilidade ligamentar e a idade. O algoritmo de tratamento é dividido nas modalidades de terapia não cirúrgicas e nas opções de tratamento cirúrgico. As cirurgias de preservação articular, as cirurgias de substituição articular e as artrodeses apresentam indicações precisas. O presente artigo apresenta uma revisão sobre o tema e uma proposta de algoritmo de tratamento para essa doença...

ABSTRACT

As regiões distais do membro inferior, incluindo o terço inferior da perna e os pés, são áreas muito propensas a perda de partes moles por trauma e lesões tróficas. A posição anterior da tíbia, com sua cobertura pouco espessa e vulnerável, além da grande quantidade de tendões, que não podem permanecer expostos, exigem uma cobertura cutânea rápida e, ao mesmo tempo, complexa. A situação em relação à direção do fluxo sanguíneo, a escassez de ventres musculares para retalhos e pele pouco elástica para retalhos randomizados viáveis complicam esta situação. No passado, retalhos com transferência intermediária foram utilizados; assim como os de perna cruzada, "cross leg", ainda são, com desvantagens importantes: dependem de mais de um tempo cirúrgico, geram muito desconforto ao paciente e nem sempre são eficazes. A microcirurgia tornou-se uma opção que contribui muito para cobertura de lesões neste aspecto, porém, depende de equipe com treinamento e material especializado. As áreas doadoras são maiores, podem causar relativo déficit funcional e utilizam troncos vasculares maiores. Os retalhos fasciocutâneos de fluxo reverso podem contribuir para a cobertura de lesões pequenas e médias nesta localização, com sequelas funcionais e estéticas menores; e menor tempo cirúrgico. Constitui eficiente opção cirúrgica por sua facilidade, segurança e versatilidade. Neste estudo, temos o objetivo demonstrar o retalho supramaleolar de fluxo reverso utilizado em 4 casos, com aplicações em situações diferentes, com resultados satisfatórios de fácil execução e reprodução.


The regions of the distal lower limb, including the 1/3 lower leg and foot areas are very prone to loss of soft tissue for trauma and ulcerations. The anterior position of the tibia, with its coverage slightly thick and vulnerable, besides the large amount of tendons, which can not remain exposed, requiring skin coverage quickly and simultaneously complex. The situation with respect to the direction of blood flow, lack of muscle bellies for flaps and skin flaps for inelastic randomized viable complicates this situation. In the past, with intermediate transfer flaps were used, as the leg cross, are still with major drawbacks: they rely on more than one occasion, generate a lot of discomfort to the patient and are not always effective. Microsurgery has become an option that helps a lot to cover injuries this point, however, depends on the team with training and specialized equipment. Donor areas are larger, can cause functional impairment and use on major vascular trunks. The fasciocutaneous flaps of reverse flow can contribute to the coverage of small and medium lesions in this location, with minor aesthetic damage and functional and less time for surgery. It constitutes effective surgical option for its ease, safety and versatility. In this study we demonstrate supramalleolous flap of reverse flow used in 4 cases, with applications in different situations, with satisfactory results easy and reproduction.

ABSTRACT

To determine the outcome of heel and ankle reconstruction with distally-based sural island flap. Case series. The study was carried out in Plastic Surgery Department, Chittagong Medical College Hospital, from January 2007 to April 2009. Twenty two subjects with soft tissue defect of heel and ankle requiring coverage were included in the study. The flap was first outlined on the posterior aspect of leg at the junction of upper and middle-third. Having incision made over the designed flap and along the line of the fascial pedicle, the vessels and the nerve were ligated at the proximal margin and severed. The skin island was elevated with the deep fascia. The sub-cutaneous fascial pedicle was then raised, with a width of 2.5 cm to include the sural nerve and vessels. The recipient defect was covered after tunneling the island flap. The donor site was closed directly when the wound was less wide and with a split skin graft when the wound was large. Results were analyzed in terms of graft acceptance and complications determined as percentage frequencies. Of the 22 patients, 15 had uneventful recovery with almost complete take of flaps. Although 5 patients showed marginal necrosis initially, they later on healed by secondary intention without requiring any secondary graft coverage. The rest two had a marked loss of flap in the peripheral part and required secondary graft coverage. Immediate venous congestion was commonly encountered which disappeared within a few days. There were no delayed complaints regarding sensation of the flaps. Distally-based sural island flap can be performed as a one-step procedure without sacrifice of any major artery. It is reliable, safe and should be the choice for reconstruction of ankle and heel defects

ABSTRACT

Introducción: El bloqueo del nervio ciático a nivel poplíteo, ya sea por vía lateral o posterior, fue descrito por varios autores. La imposibilidad de colocar a algunos pacientes en decúbito ventral para el abordaje posterior nos llevó a estudiar este abordaje medial del nervio ciático para bloqueo analgésico en cirugía de tobillo y pie. Objetivo: Evaluar la utilidad y eficacia de un nuevo abordaje del nervio ciático en el hueco poplíteo siguiendo un protocolo de analgesia posoperatoria en cirugía de tobillo y pie. Material y métodos: 40 pacientes ASA I-II programados para cirugías de tobillo y pie. Se realizó el bloqueo del nervio ciático como técnica analgésica a nivel del hueco poplíteo por vía medial. Utilizando la técnica de neuroestimulación, se inyectaron 30 ml de bupivacaína 0,375 por ciento como dosis única. Como técnica anestésica se realizó un bloqueo subaracnoideo en la misma posición. Fueron evaluados en el intraoperatorio: tiempo para realizar el bloqueo, distancia piel nervio, respuesta obtenida, punciones vasculares y contactos óseos. Luego, en el posoperatorio, se midió el grado de analgesia por escala visual análoga (EVA), necesidad de rescates, duración del bloqueo y grado de satisfacción. Resultados: El tiempo promedio para realizar el bloqueo fue de 2,55 min, y la distancia promedio piel-nervio fue de 66 ± 5 mm. En 12 (30 por ciento) pacientes la primera respuesta obtenida fue de ciático poplíteo externo, y en 28 (70 por ciento) de ciático poplíteo interno. Observamos 2 punciones vasculares y una ósea. El promedio de duración del bloqueo fue de 15,54 horas. El dolor por EVA a las 4, 8, 12 y 24 horas fue de 0,38, 0,58, 2 y 3,55, respectivamente. En 6 pacientes se requirió rescate analgésico. Discusión: En nuestra experiencia, el abordaje medial fue fácil de realizar y de gran utilidad para el manejo de la analgesia posoperatoria en cirugías de tobillo y pie, especialmente en pacientes con dificultades para posicionarse en decúbito ventral.


Introduction: The block of the sciatic nerve at the level of the popliteal space, be it by lateral or posterior approach, has been described by several authors. The impossibility of placing some patients face down for posterior approach led us to study this medial approach of the sciatic nerve for analgesic blockage in ankle and foot surgery. Objective: To evaluate the usefulness and efficiency of a new approach to the sciatic nerve in the popliteal space following a protocol of postoperative ankle and foot surgery analgesia. Material and methods: 40 ASA I-II patients programmed for ankle and foot surgery. Block of sciatic nerve was carried out as an analgesic technique at the level of the popliteal space through a medial route. Using the neurostimulation technique, 30 ml of 0,375 per cent bupivacaine was injected as a single dose. The anesthesia technique was the subaracnoid block in the same position. During the operation, the following data was evaluated: time taken for blocking, skin-nerve distance, response obtained, vascular punctures and bone contacts. Degree of analgesia by analogue visual scale (EVA), need for rescue, duration of blockage and degree of satisfaction were measured during the postoperative period. Results: The average time for blockage was 2,55 min and the average skin-nerve distance was 66 ± 5 mm. In 12 (30 per cent) patients the first response obtained was of external popliteal sciatic and in (70 per cent), of internal popliteal sciatic. We observed 2 vascular and one bone punctures. The average duration of the block was 15,54 hours. Pain by analogue visual scale at 4, 8, 12 and 24 hours was 0,38, 0,58, 2 and 3,55, respectively. Six patients required analgesic rescue. Discussion: In our experience, the medial approach was easy to carry out and very useful for managing postoperative analgesia in ankle and foot surgery, particularly in patients who had difficulties in lying on their stomach


Introdução: O bloqueio do nervo ciático a nível poplíteo, seja por via lateral ou posterior, foi descrito por vários autores. A impossibilidade de colocar alguns pacientes na posição decúbito ventral para a abordagem posterior nos levou a estudar esta abordagem medial do nervo ciático para o bloqueio analgésico em cirurgia de calcanhar e pé. Objetivo: Avaliar a utilidade e eficácia de uma nova abordagem do nervo ciático no oco poplíteo seguindo um protocolo de analgesia pósoperatória em cirurgia de calcanhar e pé. Material e métodos: Estudaram-se 40 pacientes ASA I-II programados para cirurgias de calcanhar e pé. Foi feito o bloqueio do nervo ciático como técnica analgésica na altura do escavado poplíteo por via medial. Utilizando a técnica de neuroestimulacão, injetou-se uma dose única de 30 ml de bupivacaína 0,375 por cento. Na mesma posição, foi realizado um bloqueio subaracnóideo como técnica anestésica. No intraoperatório foram avaliados: tempo para realizar o bloqueio, distancia pele-nervo, resposta obtida, punçõs vasculares e contatos ósseos; e no pós-operatório, o grau de analgesia empregando a escala visual análoga (EVA), a necessidade de resgates, a duração do bloqueio e o grau de satisfação. Resultados: O tempo médio para realizar o bloqueio foi de 2,55 min, e a distancia média pele-nervo foi 66 ± 5 mm. Em 12 (30 por cento) pacientes a primeira resposta obtida correspondeu ao ciático poplíteo externo, e em 28 (70 por cento) ao ciático popliteo interno. Houve duas punções vasculares e uma óssea. A duração média do bloqueio foi de 15,54 horas. A dor por EVA as 4, 8, 12 e 24 horas foi de 0,38, 0,58,2 e 3,55, respectivamente. Seis pacientes precisaram analgesia de resgate. Discussão: Em nossa experiencia, a abordagem medial foi fácil de realizar e de grande utilidade para o controle da analgesia pós-operatória em cirurgias de calcanhar e pé, especialmente em pacientes com dificuldades para se posicionar em decúbito ventral.

ABSTRACT

Introducción: la fractura del tobillo es frecuente. Su tratamiento puede ser quirúrgico y no quirúrgico. La principal complicación es la inestabilidad residual de la articulación, la cual afectaría adversamente su comportamiento biomecánico resultando en una pérdida de la función y una artrosis temprana. El objetivo de este estudio es determinar el resultado funcional de la técnica con placa antideslizante versus la técnica con placa lateral para el manejo de fracturas de tobillo Weber B. Materiales y métodos: se diseñó un estudio cuasiexperimental. Se incluyeron en el estudio pacientes con diagnóstico de fractura de tobillo tipo Weber B y se asignaron de manera aleatoria a dos grupos. El grupo 1 (31 pacientes) recibió una intervención quirúrgica con fijación con técnica de placa antideslizante y el grupo 2 (39 pacientes) con fijación con placa lateral. Se aplicaron escalas de valoración de tobillo en cuatro momentos. Resultados: 70 pacientes cumplieron los criterios de inclusión. Se encontró una mayor recuperación funcional en el grupo de placa antideslizante (p < 0,032) a los tres meses posquirúrgicos. Conclusión: la recuperación funcional fue mayor en los pacientes sometidos a la intervención quirúrgica con técnica de placa antideslizante comparados con la de placa lateral a las 12 semanas posquirúrgicas.

ABSTRACT

JUSTIFICATIVA E OBJETIVOS: Foram estudados os efeitos da clonidina sobre a latência, a qualidade da anestesia e a duração da analgesia do bloqueio do nervo isquiático com ropivacaína a 0,5 por cento. MÉTODO: Quarenta pacientes adultos foram submetidos a cirurgias sobre o pé e/ou a face lateral do tornozelo sob bloqueios combinados de nervos femoral e isquiático, por via anterior, em que foram alocados, segundo números aleatórios em grupo 1: 25 mL de ropivacaína a 0,5 por cento e placebo perineural; grupo 2: 2 æg.kg-1 de clonidina por via muscular e 25 mL de ropivacaína a 0,5 por cento perineural; e grupo 3: 2 æg.kg-1 de clonidina e 25 mL de ropivacaína a 0,5 por cento perineural, injetados após obtidas respostas motoras com correntes de 0,2 e 0,5 mA. A sensibilidade e a motricidade foram avaliadas por 30 minutos após o bloqueio. Um escore de efetividade total do bloqueio foi atribuído. A qualidade da anestesia cirúrgica foi classificada com sucesso ou falha, segundo a necessidade de suplementação sistêmica. A duração foi o tempo desde a realização do bloqueio até a primeira solicitação de analgésico. RESULTADOS: As latências medianas foram 5, 12,5 e 17,5 minutos nos grupos 1 a 3, respectivamente (p = 0,11). As taxas de sucesso foram de 100 por cento, 93 por cento e 75 por cento, respectivamente (p = 0,12). A duração da analgesia pós-operatória foi de 14,5, 13,5, e 13,75 horas, respectivamente (p = 0,15). CONCLUSÕES: A clonidina por via muscular ou perineural não influenciou a latência, a qualidade de anestesia ou a duração da analgesia do bloqueio do nervo isquiático com ropivacaína a 0,5 por cento.

ABSTRACT

Este trabajo analiza una muestra de 15 pacientes para evaluar el tratamiento tanto médico como quirúrgico de la Artritis Reumatoide Juvenil. Se hizo una revisión de la literatura sobre las posturas actuales en el tratamiento médico de esta enfermedad progresiva, haciendo hincapié en el importante papel que juega la cirugía preventiva como método de elección para detener o retrasar la destrucción articular. Se hace un esquema de los pasos quirúrgicos de las principales técnicas utilizadas. Al analizar los pacientes se observa que estos necesitan muchas veces múltiples intervenciones quirúrgicas en un tiempo o sucesivas en distintas articulaciones. Por supuesto que la cirugía debe ir siempre acompañada de un largo periodo de rahabilitación y mantener continuamente la medicación terapéutica

ABSTRACT

Se realizó un estudio retrospectivo (1987- 1997) en el archivo de historias médicas del Hospital "Domingo Luciani", logrando reunir 21 historias clínicas con igual número de casos, de pacientes a quienes se les cumplió artrodesis de tobillos con clavo trilaminar canulado de Smith- Petersen. 13 pacientes fueron hombres y 8 mujeres, con una edad promedio de 32,5 años, donde la osteoartrosis post-traumática representó la etiología más frecuente. La técnica quirúrgica se cumplió a través de un abordaje anterior para la resección de las superficies articulares y una incisión en cara plantar a nivel del cuerpo del calcáneo para la introducción del clavo trilaminar canulado de Smith-Petersen, según la técnica y el instrumental original diseñado para este clavo. De los 21 pacientes, 16 tuvieron un resultado excelente. Nuestro objetivo es dar a conocer un material osteosíntesis que ofrece facilidades técnicas idóneas para este tipo de procedimiento

ABSTRACT

Tratamos un caso de fractura-luxación del tobillo con luxación retrotibial del fragmento proximal del peroné, llamada fractura de Bosworth, cuyo diagnóstico fue desconocido en un primer momento, y en el cual la reducción ortopédica por maniobras clásicas fracasó. En el acto operatorio fue posible su identificación, siendo fácil la reducción y estabilización con osteosíntesis, evolucionando favorablemente, con los cuidados postoperatorios habituales a las fracturas de tobillo. Siendo una lesión infrecuente, nos pareció oportuno revisar los casos publicados, describiendo los posibles mecanismos, características radiológicas y tratamientos

ABSTRACT

Os autores fazem estudo tardio de 15 casos de artrodese do tornozelo e sua repercussäo nas articulaçöes subjacentes. Baseados na revisäo dos casos, apoiada nos exames clínicos e radiológicos, os autores concluem que o método é efetivo, apesar dos reflexos nas demais articulaçöes do pé, e que as alteraçöes ósseas verificadas näo repercutem na vida cotidiana dos pacientes.
