Foram tratados 28 pacientes num total de 29 pés, com idade média de 25,8, predomínio do sexo masculino 16 pacientes (57,2%), cor branca 25 pacientes (89,2%), lado direito 16 pacientes (57,2%). Quanto à etiologia houve um predomínio das seqüelas de fraturas de calcâneo 11 pacientes (37,9%) e poliomielite 11 pacientes (37,9%), as outras causas foram necrose do talus 2 pacientes (6,9%), barra óssea 2 pacientes (6,9%), artrose primária 2 pacientes (6,9%) e paralisia cerabral 1 paciente (3,5%). O tempo médio de consolidação foi de 3,5 meses. Foram utilizados enxerto ósseo em 11 pacientes (44%). Houve necessidade em 2 casos (6,9%) de se promover o alongamento do calcâneo para se aumentar o pitch do mesmo. A montagem é simples e se baseia em 2 anéis com fixação transóssea através de 2 fios olivados no talus e 2 no calcâneo. Como resultado foi obtido 100% de consolidação, ausência de dor e osteoporose e boa sensibilidade do pé. Das complicações encontradas além das costumeiras ou próprias do método 1 (3,5%) paciente apresentou infecção profunda em 1 dos fios. O método mostrou-se eficiente independente da etiologia com 100% de consolidação além de permitirem uma certa independência ao paciente durante o tratamento.
Objective: To present the radiographic and functional outcomes of a series of 11 cases of ankle arthrodesis performed with a circular external fixator using the Ilizarov method and a transfusion approach, conducted between January 2017 and June 2018. Methods: The patients were evaluated according to American Orthopedic Foot and Ankle Society (AOFAS) and visual analogue scale (VAS) scores. Ankle radiographs were evaluated on anteroposterior and profile views. All patients underwent a similar procedure regarding the surgical approach and assembly of the Ilizarov apparatus. Results: Eleven patients, with a mean age of 44.81 years (28-70 years), underwent surgery. The average follow-up time was 50.81 weeks (13-90 weeks). The main indication for surgery was post-traumatic secondary arthritis. The mean functional AOFAS score was 55.72 (45-64) points. An evaluation of the soft tissues revealed surgical wound healing of the transfibular approach in 9 patients (81%). All cases showed signs of superficial pin- or wire-tract infection. Union was reported in 10 patients (90.9%), and the radiographic varus deformities found in 2 patients did not exceed 7º. No additional surgical procedure was required during follow-up. Conclusion: Ankle arthrodesis performed by a transfibular approach and fixation performed by the Ilizarov method were efficient, promoted the functional restoration of the patient, considering the complexity of the cases, and resulted in a high union rate. Level of Evidence IV; Therapeutic Studies; Case Series.

Resumo Objetivo Quantificar os níveis de satisfação e dor dos pacientes submetidos a retirada ambulatorial de fixadores externos sem anestesia. Métodos Estudo prospectivo envolvendo 28 pacientes usando fixadores externos submetidos a três questionários associados à Escala Visual Analógica e Numérica da dor durante diferentes etapas da retirada. Resultados A média de dor prévia à retirada foi de 3,61. Logo após o término do procedimento, encontramos média de 6,68 para a dor mais intensa, e de 2,25 para a dor menos intensa. A variação da dor média foi de 4,43, e a dor após uma semana teve média de 2,03. A lembrança dolorosa da retirada foi menor do que a dor referida imediatamente após a retirada (média de 5,29). A predominância no estudo foi de pacientes do sexo masculino de meia-idade, e 89,3% usavam fixador externo do tipo circular. O principal segmento dos membros envolvido foi a perna, e a maior parte dos pacientes não havia feito uso de fixador externo previamente (71,4%); eles optaram pela retirada ambulatorial por se tratar de opção mais rápida (75%), e para evitar internação hospitalar (25%). O momento de dor mais intensa ocorreu durante a retirada dos pinos de Schanz (60,7%), sendo pior nas extremidades dos membros para 75% dos entrevistados. Uma maioria absoluta de 85,7% mostrou-se satisfeita após a retirada, e 82,1% afirmaram que se submeteriam novamente ao procedimento. Conclusão A retirada ambulatorial de fixadores externos sem anestesia é uma opção bem tolerada pelos pacientes, tratando-se de um procedimento com bons níveis de aceitabilidade e satisfação.
