ABSTRACT

Abstract Objective The objective of the present study was to prospectively compare the sural and propeller flaps for soft-tissues coverage of the lower extremity. The following variables were evaluated: incidence of complete or partial flap loss and donor area morbidity (primary closure versus skin graft). Methods Prospective and randomized analysis of data collected from all patients presenting with soft tissue defects of the lower third of the leg and heel treated with reverse sural or propeller flaps. Results Twenty-four patients aged between 4 and 60 years old were evaluated between 2011 and 2017. Complete coverage was obtained in 22 of the 24 patients (91.6%). Two flaps failed (8.4%). The sural flap, being the most popular option, continues to represent a safe and versatile alternative for skin defects of the lower third of the leg and heel region. Likewise, the propeller flap was a comparable option to treat these challenging defects. Conclusion Sural and propeller flaps are good options for soft tissues coverage of the lower extremity, with low complication rates (partial or total flap loss).


Resumo Objetivo O objetivo do presente estudo foi comparar prospectivamente os retalhos sural e propeller para cobertura de partes moles da extremidade inferior. Foram avaliadas as seguintes variáveis: incidência de perda total ou parcial do retalho e morbidade da área doadora (fechamento primário versus enxerto de pele). Métodos Análise prospectiva e randomizada de dados coletados de todos os pacientes apresentando defeitos em tecidos moles da extremidade distal da perna e do retropé submetidos aos retalhos em questão. Resultados Foram avaliados 24 pacientes com idades entre 4 e 60 anos, entre 2011 e 2017. Cobertura completa foi obtida em 22 dos 24 pacientes (91,6%) e observamos falha em 2 retalhos (8,4%). O retalho sural, sendo a opção mais popular, continua a representar uma alternativa segura e versátil para defeitos cutâneos do terço distal da perna e da região do calcanhar. O retalho propeller, da mesma maneira, mostrou-se uma opção comparável para o tratamento destas lesões desafiadoras. Conclusão Os retalhos sural e propeller são boas opções para a cobertura de partes moles da extremidade inferior, demostrando baixas taxas de complicações como perda parcial ou total do retalho.

ABSTRACT

ABSTRACT Objective The medial femoral condyle corticoperiosteal flap is irrigated by the descending genicular artery, and when this is absent, by the superior medial genicular artery. The descending genicular artery divides into the muscular, saphenous, and osteoarticular branches. The objective of this study was to describe the variables involved in the dissection of the medial femoral condyle flap. Methods Thirty thighs from 20 cadavers were dissected and the following variables were recorded: age, height, weight, thigh length, presence of the descending genicular artery, whether the saphenous branch originated from the descending genicular artery, the length of the branches originating from the descending genicular artery, and the diameter of the descending genicular artery and the vena comitans. Results The descending genicular artery was present in 93.3% of the specimens (28/30). The saphenous branch originated from this artery in 76.7% of the dissections (23/70). The mean distance between the origin of the descending genicular artery and the knee joint was 13.4 cm (±١.4), the mean length of the descending genicular artery was 7.5 cm (±1.5), the mean diameter of the descending genicular artery was 1.9 mm (±٠.3), and the mean diameter of the vena comitans was 1.7 mm (±٠.3). Conclusion The vascularized medial femoral condyle is a versatile option for reconstruction of musculoskeletal injuries. It allows transference of bone associated with muscle and skin, which are each nourished by independent branches. Level of Evidence IV; Case series.


RESUMO Objetivo O retalho ósseo vascularizado do côndilo femoral medial deve sua irrigação à artéria genicular descendente e, na ausência desta, à artéria genicular superior medial. A artéria genicular descendente comumente ramifica-se em: ramo muscular, safeno e osteoarticular. O estudo teve por objetivo analisar as variáveis relativas à dissecção do retalho ósseo do côndilo femoral medial. Métodos Foram dissecados 30 joelhos (20 cadáveres), registrando-se: idade; estatura; peso; comprimento da coxa; presença da artéria genicular descendente; se o ramo safeno tem origem na artéria genicular descendente; comprimento dos ramos da artéria genicular descendente e os diâmetros da artéria genicular descendente e veia comitante. Resultados A artéria genicular descendente esteve presente em 93,3% dos espécimes (28/30). O ramo safeno originou-se da artéria genicular descendente em 76,7% das dissecções (23/70). Distância entre origem da artéria genicular descendente e interlinha articular = 13,4 (±1,4) cm, comprimento da artéria genicular descendente = 7,5 (±1,5) cm, diâmetro da artéria genicular descendente = 1,9 (±0,3) mm, diâmetro da veia comitante = 1,7 (±0,3) mm. Conclusão O retalho ósseo vascularizado do côndilo femoral medial mostrou-se a opção versátil para reconstrução de lesões do sistema músculo-esquelético. Permite a elevação de retalho ósseo associado à pele e tecido muscular, cada qual nutrido por ramos independentes. Nível de Evidência IV; Série de casos.

ABSTRACT

ABSTRACT Objective: To analyze 10 consecutive cases of microsurgical arteriovenous loops created to reconstruct complex injuries from March 2011 to May 2012. Methods: This observational cohort-type study conducted by the Hand and Microsurgery Group at the HC-FMUSP included patients who were candidates for microsurgical reconstruction as a last alternative to amputation of the limb with proven absence of adequate recipient vessels for primary microsurgical anastomosis, in a prospective and consecutive manner. We analyzed 14 variables (epidemiological, clinical, procedure-related, and outcome) in patients who underwent reconstruction using an arteriovenous loop utilizing a single-stage or two-stage procedure. Results: The injuries were mostly traumatic (80%). The success rate of the single-stage procedure was 75%, and 17% for the two-stage procedure. The rate of preservation for the injured limb was 44%. Conclusion: This study reinforces the more recent understanding that the indication for single-stage or two-stage reconstruction should be individualized; our findings favor the single-stage reconstruction. This technique should be used in selected cases, as a last reconstructive alternative before amputation, and further studies are necessary to confirm its safety and efficacy in our practice. Level of Evidence IV; Case series.


RESUMO Objetivo: Analisar dez casos consecutivos de alças vasculares microcirúrgicas realizadas para reconstrução de feridas complexas no período de março de 2011 a maio de 2012. Métodos: Estudo de observação, analítico do tipo coorte, realizado pelo Grupo de Mão e Microcirurgia do Instituto de Ortopedia e Traumatologia do HC-FMUSP. Foram incluídos, prospectivamente e de maneira consecutiva, os pacientes candidatos à reconstrução microcirúrgica como última alternativa à amputação do membro, com comprovada ausência de vasos receptores adequados para anastomose microcirúrgica primária. Foram analisadas 14 variáveis (epidemiológicas, clínicas, relacionadas ao procedimento e resultados) nos pacientes submetidos à reconstrução com alça em tempo único e em dois tempos. Resultados: As lesões foram de etiologia traumática em sua maioria (80%). A taxa de sucesso do procedimento em tempo único foi de 75%, e em dois tempos de 17%. A taxa de manutenção do membro lesado foi de 44%. Conclusão: Este estudo reforça o entendimento mais recente de que a indicação de reconstrução em um ou dois tempos deve ser individualizada, e nossos resultados favorecem a reconstrução em tempo único. A técnica deve ser usada em casos selecionados, como última opção reconstrutiva à amputação, sendo necessários mais estudos para atestar sua segurança e eficácia em nosso meio. Nível de Evidência IV; Série de casos.

ABSTRACT

Brachial plexus injuries, in all their severity and complexity, have been extensively studied. Although brachial plexus injuries are associated with serious and often definitive sequelae, many concepts have changed since the 1950s, when this pathological condition began to be treated more aggressively. Looking back over the last 20 years, it can be seen that the entire approach, from diagnosis to treatment, has changed significantly. Some concepts have become better established, while others have been introduced; thus, it can be said that currently, something can always be offered in terms of functional recovery, regardless of the degree of injury. Advances in microsurgical techniques have enabled improved results after neurolysis and have made it possible to perform neurotization, which has undoubtedly become the greatest differential in treating brachial plexus injuries. Improvements in imaging devices and electrical studies have allowed quick decisions that are reflected in better surgical outcomes. In this review, we intend to show the many developments in brachial plexus surgery that have significantly changed the results and have provided hope to the victims of this serious injury.

ABSTRACT

OBJETIVO: O Harris Hip Score é instrumento de avaliação específica, desenvolvido originalmente para avaliar os resultados da artroplastia total de quadril. O objetivo deste estudo foi traduzir e adaptar culturalmente este instrumento para a língua portuguesa. MÉTODO: O método de tradução e adaptação cultural do Harris Hip Score envolveu quatro etapas: 1 - tradução inicial; 2 - retrotradução; 3 - apreciação das versões com elaboração da versão de consenso; 4 - pré-teste comentado com elaboração da versão final. RESULTADOS: A versão de consenso foi aplicada em 30 pacientes com afecção do quadril, sendo verificadas dificuldades no entendimento de algumas expressões, as quais foram substituídas por termos de mais fácil entendimento. Na reaplicação do questionário com a nova versão houve entendimento por 100 por cento dos pacientes no que diz respeito ao sentido semântico, idiomático e contextual. CONCLUSÃO: A versão brasileira do Harris Hip Score permitiu a disponibilização de mais este instrumento para avaliação da qualidade de vida de pacientes com afecções do quadril. Há necessidade de um estudo de avaliação da confiabilidade e validade da versão adaptada culturalmente, a qual já está em desenvolvimento.


OBJECTIVE: The Harris Hip Score is a specific evaluation tool, originally developed to assess the results of hip arthroplasty. The objective of this study was to translate and cross-culturally adapt the Harris Hip Score for the Portuguese language. METHOD: The method of translating and culturally adapting the Harris Hip Score involved four steps: 1 - initial translation, 2 - back-translation, 3 - evaluation of the pre-final versions with the development of a consensus version, 4 - commented pre-test with development of the final version. RESULTS: The consensus version was applied to thirty patients with hip disorders. Some difficulties were identified in understanding some expressions, which were replaced by more commonly-used expressions. When the questionnaire was re-applied, it was understood by 100 percent of the patients, in relation to the semantic, idiomatic and conceptual meanings. CONCLUSION: The Brazilian version of the Harris Hip Score provides another important tool for assessing quality of life of patients with hip disorders. A further study is currently underway to evaluate the reliability and validity of the culturally adapted version.
