Correlation between quality of life and the clinical results of patients with leprosy with drop foot after tendon transfer / Avaliação de pacientes com hanseníase pós transposição tendínea para pé caído e sua correlação com a qualidade de vida

ABSTRACT Objective: To evaluate the functional results of surgically correcting drop foot in patients with leprosy and compare their SALSA, Social Participation, and AOFAS score. Methods: Overall, 22 patients were subjected to posterior tibial tendon transfer via the subcutaneous route to the foot dorsum with an average follow-up of 56 months (min 12, max 70). In our sample, 15 of the enrolled patients were men and seven, women, aged between 20 and 73 years old who were operated on from January 2014 to December 2017. The Pearson's correlation test (r) was used to measure the correlation among those scales. A p < 0.05 was considered significant between the pre- and pos-operative AOFAS scale scores. Results: Pre-operative average AOFAS score was 59.6 (min 35, max 74) and 77.2 postoperative (min 36, max 97) (p < 0.0001), postoperative Salsa and Social Participation scale, 30.6 and 22.5, respectively. Statistical analysis suggests a strong positive correlation between AOFAS and Salsa scales (r = −0.83) and AOFAS and social participation (r = −0.78). Average dorsiflexion was 5.4 degrees. Conclusion: The surgical correction of drop foot positively affects the quality of life and social participation of patients with leprosy. Level of Evidence III, Retrospective Study.

Estudio biométrico de la distribución de los ramos motores del nervio fibular superficial en el compartimiento lateral de la pierna en individuos brasileiros: implicancias clínicas y variaciones / Biometric study of the distribution of the motor branches of the superficial fibular nerve in the lateral compartment of the leg in Brazilian individuals: clinical implications and variations

El propósito del presente estudio fue conocer la distribución de los ramos motores del nervio fibular superficial (NFS) y de sus respectivas penetraciones en los músculos fibulares en relación al ápice de la cabeza de la fíbula, dividiendo el compartimiento lateral de la pierna en tres regiones a fin de hacer posible una visión más segura de sus correlaciones clínicas y quirúrgicas. A través de disección, se estudiaron 60 piernas pareadas de 30 cadáveres adultos, de ambos sexos, Brasileños, con edad promedio de 44,9 años, siendo 8 de sexo femenino y 22 del masculino. Después de la disección se registraron las distancias de los puntos de penetración de los ramos del NFS en los músculos fibular largo (mFL) y corto (mFC), localizándolos en los tercios proximal, medio o distal, según fuere el caso. Se observó que el mayor número de ramos penetraron en el mFL a nivel de la parte distal del tercio proximal de la pierna, mientras que en el mFC lo hicieron en las partes proximal y distal del tercio medio de la pierna. Los ramos motores para el mFL penetraban en el vientre muscular entre 48,06 y 141,56 mm, y los ramos para el mFC lo hicieron entre 163,34 y 209,67 mm del origen del nervio. No hubo diferencias estadísticamente significativas ni entre los lados derecho e izquierdo ni entre genéros. Independiente de las diferencias metodológicas entre los estudios disponibles, el detalle de la distribución nerviosa en este compartimiento, permitirá una mayor precisión en el momento de elegirse un área para colgajo de injerto autólogo y una menor chance de lesiones iatrogénicas durante cirugías de la región.

The purpose of the present study was to know the distribution of the motor branches of the superficial fibular nerve (SFN) and their respective motor points in the fibular muscles in relation to the apex of the head of the fibula, dividing the lateral compartment of the leg in three regions in order to make possible a safer view of your clinical and surgical correlations. Through dissection, 60 paired legs of 30 adult cadavers, of both sexes, Brazilians, with an average age of 44.9 years, 8 being female and 22 male, were studied. After the dissection, the distances of the motor points of the NFS branches in the fibularis longus (FLm) and brevis (FBm) muscles were recorded, locating them in the proximal, middle or distal thirds. It was observed that the largest number of branches penetrated the FLm at the level of the distal part of the proximal third of the leg, while in the FBm they did so in the proximal and distal parts of the middle third of the leg. The motor branches for the FLm penetrated into the muscular belly between 48.06 and 141.56 mm, and the branches for the FBm did between 163.34 and 209.67 mm of the origin of the nerve. There were no statistically significant differences between the right and left sides or between genres. Regardless of the methodological differences between the available studies, the detail of the nervous distribution in this compartment will allow a greater precision at the time of choosing an area for autologous graft flap and a lower chance of iatrogenic injuries during surgeries of the region.

Use of superficial peroneal nerve graft for treating peripheral nerve injuries / Emprego do enxerto do nervo fibular superficial para tratamento de lesões de nervos periféricos

To evaluate the clinical results from treating chronic peripheral nerve injuries using the superficial peroneal nerve as a graft donor source. METHODS: This was a study on eleven patients with peripheral nerve injuries in the upper limbs that were treated with grafts from the sensitive branch of the superficial peroneal nerve. The mean time interval between the dates of the injury and surgery was 93 days. The ulnar nerve was injured in eight cases and the median nerve in six. There were three cases of injury to both nerves. In the surgery, a longitudinal incision was made on the anterolateral face of the ankle, thus viewing the superficial peroneal nerve, which was located anteriorly to the extensor digitorum longus muscle. Proximally, the deep fascia between the extensor digitorum longus and the peroneal longus muscles was dissected. Next, the motor branch of the short peroneal muscle (one of the branches of the superficial peroneal nerve) was identified. The proximal limit of the sensitive branch was found at this point. RESULTS: The average space between the nerve stumps was 3.8 cm. The average length of the grafts was 16.44 cm. The number of segments used was two to four cables. In evaluating the recovery of sensitivity, 27.2% evolved to S2+, 54.5% to S3 and 18.1% to S3+. Regarding motor recovery, 72.7% presented grade 4 and 27.2% grade 3. There was no motor deficit in the donor area. A sensitive deficit in the lateral dorsal region of the ankle and the dorsal region of the foot was observed. None of the patients presented complaints in relation to walking. CONCLUSIONS: Use of the superficial peroneal nerve as a graft source for treating peripheral nerve injuries is safe and provides good clinical results similar to those from other nerve graft sources.

Avaliar resultados clínicos do tratamento das lesões crônicas de nervos periféricos com o nervo fibular superficial como fonte doadora de enxerto. MÉTODOS: Estudo de 11 pacientes com lesões de nervos periféricos nos membros superiores tratados com enxerto do ramo sensitivo do nervo fibular superficial, com intervalo médio de 93 dias entre a data de registro da lesão e a cirurgia. Foram observadas lesões do nervo ulnar em oito pacientes e do nervo mediano em seis. Em três ambos os nervos foram lesados. Na cirurgia faz-se incisão longitudinal na face anterolateral no tornozelo, visualiza-se o nervo fibular superficial, situado anteriormente ao músculo extensor longo dos artelhos. Proximalmente disseca-se a fáscia profunda entre os músculos extensor longo dos artelhos e o fibular longo. A seguir, identifica-se o ramo motor do músculo fibular curto, um dos ramos do nervo fibular superficial. O limite proximal do ramo sensitivo encontra-se nesse ponto. RESULTADOS: A média do espaço entre os cotos nervosos foi de 3,8 cm, comprimento médio dos enxertos de 16,44 cm, número de segmentos usados de dois a quatro cabos. Na avaliação da recuperação da sensibilidade, 27,2% evoluíram para S2+, 54,5% para S3 e 18,1% para S3+. Quanto à recuperação motora, 72,7% apresentavam grau 4 e 27,2%, grau 3. Não houve déficit motor da área doadora, observou-se déficit sensitivo na região dorso lateral do tornozelo e dorsal do pé. Nenhum paciente apresentou queixas à deambulação. CONCLUSÕES: O uso do nervo fibular superficial no tratamento das lesões de nervos periféricos como fonte de enxerto é seguro e proporciona resultados clínicos semelhantes a outras fontes de enxerto de nervos.

Tendinopatia dos fibulares: [revisão] / Fibular tendinopathy: [review]

JUSTIFICATIVA E OBJETIVOS: Ressaltar as características do acometimento dos tendões fibulares e o seu tratamento. O objetivo deste estudo foi analisar as diferenças referentes à nomenclatura do acometimento dos tendões, a etiologia, incidência, sintomatologia e o tratamento da tendinopatia dos fibulares. CONTEÚDO: Foram consultados os bancos de dados da Pubmed, CAPS e Google acadêmico, bem como revistas científicas com as seguintes palavras-chaves: tendinose, tendinopatia, tendinite e tenossinovite dos músculos fibulares. Além disso, livros também foram verificados. Foram revisadas 33 referências bibliográficas e foi encontrado que a tendinopatia está ligada a um processo degenerativo, a etiologia é de caráter multifatorial, sua maior incidência é em esportes como basquete, balé e atletismo. Nos achados clínicos, encontra-se fraqueza muscular e nem sempre há dor. CONCLUSÃO: Quando há prevalência de processo degenerativo a nomenclatura mais correta a ser utilizada é tendinopatia, ocorrendo com maior frequência em esportes e não sendo obrigatória a presença de dor. Apesar de o tratamento ser pouco descrito, os exercícios excêntricos parecem trazer os melhores resultados, porém, há a necessidade de outros estudos que abordem o tema.

BACKGROUND AND OBJETIVES: To describe the characteristics of the involvement of the peroneal tendons and their treatment. The aim of this study was to analyze the differences regarding the nomenclature of the affected tendon, the etiology, incidence, symptoms and treatment of peroneal tendinopathy. CONTENTS: Web pages for search (PubMed, Google scholar and CAPS) and journals were consulted with the following keywords: tendinosis; tendinopathy, tendinitis and tenosynovitis of the peroneal muscles. In addition, books were also checked. We reviewed 33 references and found that tendinopathy is related to a degenerative process, the etiology is multifactorial, and its highest incidence is in sports like basketball, ballet and athletics. In clinical findings, there is muscle weakness and there is not always pain. CONCLUSION: When there is prevalence of the degenerative process more accurate nomenclature to be used is tendinopathy, occurring more frequently in sports and not being required the presence of pain. Although the treatment is not well described, eccentric exercises seem to bring the best results, however, there is a need for further studies that will address this issue.

Inervación de los músculos fibulares largo y corto en individuos chilenos: estudio anatómico y biométrico / Innervation of the fibularis longus and brevis muscles in chilean individuals: anatomic and biometric study

La inervación de los músculos del compartimiento lateral de la pierna es conocida desde un punto de vista general y su dependencia del nervio fibular superficial (NFS) es descrita en la mayoría de los textos clásicos. Sin embargo, detalles del número de ramos nerviosos que reciben los músculos y a que nivel se encuentran sus puntos motores es poco conocido, sobretodo en nuestra población. Basado en lo anterior y con el propósito de aportar datos respecto a las variables mencionadas y determinar niveles de origen y localización de los puntos motores de los músculos fibulares largo y corto, se realizó un estudio anatómico y biométrico en 16 piernas formolizadas de individuos adultos, chilenos. Se realizó disección por planos, identificando en la parte proximal de la pierna el nervio fibular común (NFC) y su punto de división en nn. fibular superficial (NFS) y fibular profundo (NFP), localizando los ramos primarios (R1,R2,R3 o más) dirigidos a los músculos en estudio. Para determinar su punto de origen y punto de penetración en éstos, se identificó la parte más prominente del epicóndilo lateral del fémur, desde el cual se registró la distancia entre este punto de referencia y las variables mencionadas. Cuando hubo subdivisiones en ramos secundarios (RS), se registró también su punto de origen y punto de penetración en el vientre muscular. En el m. fibular largo se observó en los 16 casos R1 y R2; 13 casos con R1, R2 y R3; 5 casos con R1, R2, R3 y R4 y 1 presentó 5R. El R1 provino del NFC en 6 casos (37,5 por ciento), del NFS en 9 (56,3 por ciento) y del nervio cutáneo dorsal medial (división precoz de NFS) en 1 (6,3 por ciento); el R2 se originó en el NFC en 2 casos (12,5 por ciento), del NFS en 13 (81,3 por ciento) y del nervio cutáneo dorsal medial en 1(6,3 por ciento); el R3 fue emitido por el NFS en 11 casos y por el nervio cutáneo dorsal intermedio (división precoz NFS) en 2 casos. Los ramos primarios se subdividieron hasta en 5 RS. El m. fibular corto...

The innervation of the muscles of the lateral compartment of the leg is known from a general point of view and its dependence of the superficial fibular nerve (SFN) is described in the majority of the classic texts. Nevertheless, there is little information regarding detail of the number of nervous branches that muscles receive, or the location of its motor points, principally in our population. The objective of this study was to contribute to anatomic knowledge of the mentioned variables and determine the origin levels of muscular branches and the motor points location in the fibularis longus and fibularis brevis muscles. We carried out an anatomical and biometric study in 16 cadaveric legs fixed in formaldehyde of adult, Chilean individuals. Dissections were made, identifying in the proximal part of the leg the common fibular nerve (CFN) and its division point in superficial (SFN) and deep (DFN) fibularis nerves, locating the primary branches (R1, R2, R3 or more) directed for the muscles in the study.To determine the origin level of muscular branches and motor point, we identified the most prominent part of the lateral epicondyle of femur, from which the distance was recorded between this point of reference and the mentioned variables. When there were subdivisions in secondary branches (SB), also we recorded its point of origin and motor point in the muscular belly. In the fibularis longus muscle we observed R1 and R2 in 16 cases; R1, R2 and R3 in 13 cases; R1, R2, R3 and R4 in 5 cases and 5R in one case. The R1 originated from the CFN in 6 cases (37.5 percent), from the SFN in 9 (56.3 percent) and from the medial dorsal cutaneous nerve (SFN precocious division) in 1 (6.3 percent); The R2 originated in the CFN in 2 cases (12.5 percent), of the SFN in 13 (81.3 percent) and of the medial dorsal cutaneous nerve in 1 (6.3 percent); the R3 was emitted by the SFN in 11 cases and by the intermediate dorsal cutaneous nerve (SFN precocious division) in 2...

Se presenta el caso de un hombre de 34 años con cuadro clínico crónico de úlceras cutáneas y monoparesia inferior izquierda. Electromiografía que evidencia neuropatía sensitiva del nervio fibular superficial izquierdo; estudios ecográficos sin evidencia de enfermedad arteriovenosa. El paciente no presentó mejoría de lesiones cutáneas con inmunosupresión agresiva. En la biopsia de piel y de nervio sural se encontraron trombos y ausencia de infiltrado inflamatorio compatibles con vasculopatía y neuropatía trombóticas. Se documentó la presencia de anticoagulante lúpico, TPT prolongado y anticuerpos anti-B2 glicoproteína 1 positivos.

This following case report describes a 34 years-old man with chronic clinical skin ulcers and left lower monoparesis. Electromyography revealed sensory neuropathy of the left superficial fibular nerve; the ecographic studies showed absence of artery or venous disorder. The patient showed no improvement of skin lesions with aggressive immunosuppression. The biopsy of the skin and the sural nerve reported thrombi and absence of inflammatory infiltrates; findings that support the diagnosis of thrombotic vasculopathy and neuropathy. The presence of lupus anticoagulant, prolonged PTT and positive anti-B2 glycoprotein antibodies were documented.
