Fixation of Intertrochanteric Fractures with Dynamic Hip Screws: Randomized Controlled Trial Comparing Hardinge and Minimally Invasive Approaches.

Objective To compare the techniques for the osteosynthesis of intertrochanteric fractures with dynamic hip screws (DHSs) through the Hardinge and minimally-invasive access routes of the hip, evaluating the operative time, the degree of pain in the immediate postoperative period, the hematimetric loss, and the functional aspects of active mobility. Methods A randomized, double-blinded clinical trial in which 66 patients with intertrochanteric fractures were submitted to osteosynthesis by DHS. The patients were divided into a test group, submitted to the minimally-invasive access, and a control group, in whom the surgery was performed through the Hardinge route. Results Patients submitted to the minimally-invasive treatment presented a lower degree of postoperative pain compared to the group treated by the Hardinge lateral route ( p < 0.001), as well as lower hematimetric loss ( p < 0.001), shorter operative time ( p < 0.001), and improvement in immediate postoperative active mobility tests ( p <0.05). Conclusion The study demonstrated the clinical superiority of the minimally-invasive access route parameters analyzed in relation to the Hardinge access for the fixation of intertrochanteric fractures when DHS is the choice osteosynthesis method. Level of evidence I.

Resumo Objetivo Comparar as técnicas de osteossíntese de fraturas intertrocantéricas com o parafuso dinâmico de quadril (dynamic hip screw, DHS, em inglês) pelas vias de acesso de Hardinge e minimamente invasiva do quadril, avaliando o tempo cirúrgico, o grau de dor no pós-operatório imediato, a perda hematimétrica, e os aspectos funcionais de mobilidade ativa. Métodos Estudo clínico randomizado e duplo-cego, em que 66 pacientes com fratura intertrocantérica foram submetidos a osteossíntese com DHS. Os pacientes foram divididos em um grupo teste, submetidos ao acesso minimamente invasivo, e um controle, em que a cirurgia foi realizada pela via de Hardinge. Resultados Os pacientes submetidos ao tratamento pela via minimamente invasiva apresentaram um grau de dor pós-operatória inferior em comparação ao grupo tratado pela via lateral de Hardinge (p< 0,001), assim como menor perda hematimétrica (p< 0,001), menor tempo operatório (p< 0,001), e melhora nos testes de mobilidade ativa pós-operatória imediata (p< 0,05). Conclusão O estudo demonstrou a superioridade clínica nos parâmetros analisados da via de acesso minimamente invasiva em relação ao acesso de Hardinge para a fixação de fraturas intertrocantéricas, quando o DHS for a opção de osteossíntese escolhida. Nível de evidência I.

Effectiveness of treatment of transtrochanteric fractures with dynamic hip screws using minimally invasive access / Eficácia do tratamento das fraturas transtrocanterianas com dynamic hip screw com acesso minimamente invasivo

OBJECTIVE: To analyze the short-term results from treating unstable intertrochanteric fractures with Dynamic Hip Screws (DHS), using a minimally invasive route, focusing on the functional aspects and complication and mortality rates of the method. METHODS: This was a prospective longitudinal study on 140 patients who underwent fixation of transtrochanteric fractures with the DHS system with a lateral minimally invasive access in the hip, between January and December 2013. The patients were evaluated pre and postoperatively (after six months of follow-up) by means of the Parker and Palmer mobility score. Women comprised 65.7% of the sample, and 54.3% of the fractures were on the right side. The patients' mean age was 80 years, ranging from 60 to 93 years. RESULTS: We observed an overall decrease in the mobility score and an increase in the degree of dependence over the short term. However, we encountered only two deaths in the study sample and there were no cases of infection or nonunion. CONCLUSION: Despite the efficacy of the treatment with DHS, with high rates of fracture consolidation and a low mortality rate, we noted that the patients still showed significant functional limitation at the follow-up six months after the operation.

OBJETIVO: Analisar os resultados do tratamento de fraturas transtrocantéricas instáveis com o Dinamic Hip Screw (DHS) por via minimamente invasiva e avaliar aspectos funcionais, taxas de complicação e óbitos do método, em curto prazo. MÉTODOS: Trata-se de um estudo longitudinal prospectivo, com 140 pacientes submetidos à fixação de fraturas transtrocantéricas com sistema DHS, com acesso minimamente invasivo lateral do quadril, de janeiro a dezembro de 2013. Os pacientes foram avaliados pré e pós-operatoriamente (com seis meses de seguimento), de acordo com o escore de mobilidade de Parker e Palmer. A amostra apresentou 65,7% de mulheres, com o lado direito mais acometido (54,3%). A média de idade foi de 80 anos, variação entre 60 e 93. RESULTADOS: Notamos uma diminuição global no escore de mobilidade e aumento no grau de dependência desses pacientes em curto prazo. No entanto, obtivemos apenas dois óbitos na amostra estudada e nenhuma infecção ou falha na consolidação das fraturas. CONCLUSÃO: Apesar da eficácia do tratamento com DHS, com elevados índices de consolidação e baixa taxa de mortalidade, notamos que os pacientes, ainda assim, apresentam uma limitação funcional significativa no seguimento até seis meses pós-operatórios.

Avaliação da qualidade de vida submetidos à hemiartroplastia dos pacientes do quadril / Evaluation of the quality of life of patients undergoing hemiarthroplasty of the hip

Análise comparativa da qualidade de vida dos pacientes submetidos à hemiar troplastia do quadril, no pré-operatório, com três e seis meses de operados, por meio do questionário SF-36 (Medical Outcomes Study 36 - Item short form health survey). Métodos: Estudo prospectivo em 12 pacientes com fratura do colo do fêmur, submetidos à artroplastia parcial do quadril, de junho de 2013 a julho de 2014. Houve predomínio do sexo feminino, com 58,3%. A média de idade foi de 83 anos e em 91,7% foi decorrente de queda da própria altura. Foram aplicados os questionários SF-36 no pré-operatório e três e seis meses do pós-operatório. Resultados: Com relação à saúde física, os pacientes apresentaram baixa pontuação na capacidade funcional e nos aspectos físicos. Boa pontuação no subitem estado geral e alta pontuação no quesito dor. A vitalidade, os aspectos sociais e a saúde mental tiveram pontuações moderada e baixa no que diz respeito aos aspectos emocionais. Conclusão: Com a amostra analisada, podemos dizer que o procedimento de hemiartroplastia do quadril, nas fraturas do colo do fêmur instáveis, em pacientes com baixa demanda funcional analisados no período pós-operatório de seis meses, permite, sim, a manutenção da qualidade de vida.

This was a comparative analysis on the quality of life of patients who underwent hemiarthroplasty of the hip, assessed before the operation and 3 and 6 months after the operation, by means of the SF-36 questionnaire (Medical Outcomes Study 36-Item Short Form health survey). METHODS: A prospective study was conducted on 12 patients with femoral neck fractures who underwent partial hip arthroplasty between June 2013 and July 2014. Female patients predominated (58.3%). The mean age was 83 years and, in 91.7%, the fracture was due to falling from a standing position. The SF-36 questionnaire was applied before the operation and 3 and 6 months after the operation. RESULTS: With regard to physical health, the patients presented low scores for functional capacity and physical aspects. They had good scores for the subitem of general state and high scores regarding pain. Vitality, social aspect and mental health had moderate scores and emotional aspects had a low score. CONCLUSION: With the sample analyzed here, we can say that the hip hemiarthroplasty procedure for cases of unstable femoral neck fractures, in patients with low functional demands analyzed over a postoperative period of 6 months, does indeed allow quality of life to be maintained.
