Idioma: es.
Resumo: Objetivo: Evaluar los resultados objetivos y subjetivos obtenidos luego de una osteosíntesis con placas en T bloqueadas volares, colocadas mediante una técnica mínimamente invasiva, en fracturas de radio distal con extensión metafisaria. Materiales y Métodos: Evaluación retrospectiva de seis pacientes adultos que presentaron fracturas inestables de radio distal, extrarticulares o articulares parciales, con extensión metafisaria, tratadas quirúrgicamente con placas en T largas de compresión bloqueadas volares, mediante una técnica mínimamente invasiva, entre 2007 y 2012. Edad promedio: 40.17 años. Fracturas de tipo 23A3 (n=6) de la Clasificación AO/OTA. Se realizó la reducción indirecta, bajo radioscopia y, a través de dos pequeñas incisiones, se deslizó, en forma percutánea, una placa bloqueada volar en T. Se analizaron los parámetros radiográficos, el rango de movimiento y la fuerza. Los resultados subjetivos fueron evaluados usando la escala DASH y la escala analógica visual. Resultados: Tiempo de consolidación promedio: 2.4 meses. Los resultados radiográficos no mostraron diferencias significativas entre el primero y el último control al año de seguimiento. Flexión y extensión promedio: 70° y 60°, pronación y supinación: 79° y 80°, respectivamente. Fuerza de prensión promedio: 78,4%. Puntaje DASH 19,82; escala analógica visual 1,5 puntos. Conclusiones: Las técnicas mínimamente invasivas reducen el daño quirúrgico y las complicaciones. Son una opción en pacientes con daño grave de partes blandas, conminución metafisaria y trauma de alta energía. La colocación de placas volares bloqueadas percutáneas es un procedimiento técnicamente demandante, permite obtener fijaciones estables y restaurar la anatomía radial en fracturas de radio distal con extensión metafisaria.

Objective: To evaluate objective and subjective outcomes after closed reduction and minimally invasive volar locked T-plate osteosynthesis for distal radius fractures with metaphyseal involvement. Methods: We retrospectively evaluated six patients treated with minimally invasive volar locked T-plate osteosynthesis for unstable extra-articular or partial articular distal radius fractures with metaphyseal involvement, between 2007 and 2012. Average age: 40.17 years. According to the AO/OTA classification, all patients had 23A3 type fractures. Indirect reduction was performed. Two volar small incisions were made; a volar locked compression T-plate was introduced in the sub-muscular plane, under radioscopic guidance. Analysis included radiological parameters, range of motion and strength. Subjective results were assessed using DASH score and the Visual Analogue Scale. Results: All fractures healed within 2.4 months. Radiographic outcomes showed no differences between the first postoperative control and the last one at one-year follow-up. Average flexion and extension 70° and 60°, pronation and supination: 79° and 80°. Grip strength: 78.4%. DASH score 19.82 and visual analogue scale: 1.5 points. Conclusions: Minimally invasive technique decreases surgical injury and complications. It is an option in patients with metaphyseal comminution, severe soft tissue injuries and high energy trauma. Percutaneous volar locked compression plate allows to obtain a stable fixation and to restore distal radius anatomy in radius fractures with metaphyseal involvement.

Título: Placa hiperpigmentada en la palma de mano de un anciano / Hyperpygmented patch in a old man´s palm
Fonte: Dermatol. peru;21(2):87-90, abr.-jun. 2011. ilus.
Idioma: es.
Resumo: Se presenta el caso de un paciente anciano que acude por una placa marrón en la palma de una mano asintomática. Se comprometen posteriormente la otra palma y las plantas de ambos pies. Presenta serología treponémica positiva, dermatitis en banda con infiltrado inflamatoria a predominio de células plasmáticas, tinción argéntica sugerente y respuesta terapéutica por lo que se concluye que se trataba de un cuadro de sífilis secundaria simulando una tina negra.

We present the case of an old man who seeks medical care because a brown patch in a hand palm without symptoms. A couple of weeks after that both soles and the other hand has been compromised too. We get a positive luetic serology, band dermatitis with great amount of plasma cells, suggestive silver dye, and therapeutic response. We conclude that the case was a luetic secondarily mimic black tinea.

Idioma: en.
Resumo: Introduction: The palmaris longus muscle it is considered one of the most variable muscles in the human body, and its agenesis is the most frequent anatomic variation. The aim of this study was to determine the prevalence of unilateral and bilateral agenesis of palmaris longus muscle for the subjects in the city of Jataí, Goiás. Material and methods: 740 subjects, 279 men and 461 women, in the age of 10-70 years old, were observed through clinical inspection in both forearms to absence of the tendon of palmaris. The data were described in percentage values and the absence of the muscle was analyzed statistically (Chi square test; P < 0.05). Results: The bilateral presence was identified in 73.5%, the absence on the left side in 7.8%, on the right in 6.5% and bilateral absence was observed in 12.2% of subjects. Among women and men the percentage values was 9.3%, 7.3%, 13.1% and 5.4%, 5%, 10.7%, respectively to agenesis in left side, in right side and bilateral agenesis. The unilateral/bilateral agenesis was more frequent in women (29.7%) than in men (21.1%; P < 0.05). Bilateral absence was 12.4% in right handed subjects and 9.1% in left handed subjects (P > 0.05). Left and right handed subjects showed absence of muscle similar in both forearms (P > 0.05). Conclusion: most subjects studied showed bilateral presence of palmaris longus muscle, the agenesis was significantly more common in women and with similar percentage in right and left handed subjects.

Título: Transposición tendinosa con el palmar mayor para restablecer la extensión de los dedos en la parálisis del nervio radial / Tendinous transposition with palmaris major to restore the fingers extension in the radial nerve paralysis
Fonte: Rev. cuba. ortop. traumatol;25(1):56-68, ene.-jun. 2011.
Idioma: es.
Resumo: INTRODUCCIÓN: Cuando se realizan transferencias tendinosas para restablecer la extensión de los dedos por parálisis del nervio radial ha sido motivo de controversia entre la decisión de que músculo a utilizar, el cubital anterior o palmar mayor. El objetivo de esta investigación es mostrar nuestra experiencia con el empleo del músculo palmar mayor. MÉTODOS: Se realizó un estudio longitudinal, en 39 pacientes con el diagnóstico de parálisis del nervio radial, donde se evaluó los resultados funcionales de las transposiciones tendinosas para restablecer la extensión de los dedos. El palmar mayor fue empleado en 27 pacientes, 15 por vía subcutánea y 12 a través de la membrana ánteríor ósea, y se utilizó cubital anterior en 12 pacientes como grupo control. RESULTADOS: La evaluación de la extensión de las articulaciones metacarpofalángicas de los dedos fue excelente y buena en 37 de los 39 pacientes sin que existiera asociación estadística en relación al músculo empleado. La fuerza muscular flexora de la muñeca después de la cirugía disminuyó a grado 3 en 11 de los 12 pacientes en que se utilizó el cubital anterior a diferencia de los que utilizaron el palmar mayor en los que la fuerza fue de grado 4 en 17 de los 27. La complicación más frecuente fue la desviación radial de la muñeca que se presentó en 4 pacientes, en todos se habÝa utilizado el cubital anterior. CONCLUSIONES: El músculo palmar mayor es la alternativa más recomendada para restablecer la extensión de los dedos en las parálisis del nervio radial

INTRODUCTION: When tendinous transfers are carried out to restore the finger extension due to radial nerve paralysis, there are controversies in the decision of which muscle be used, the anterior cubital one or the palmaris major. The objective of present research is to show our experience with the use of the palmaris major muscle. METHODS: A longitudinal study was conducted in 39 patients diagnosed with radial nerve paralysis, where we assessed the functional results of tendinous transpositions to restore the finger extension. The palmaris major was used in 27 patients, 15 by subcutaneous route and 12 through the interosseous membrane and the anterior cubital one was used in 12 patients as control group. RESULTS: The assessment of the extension of fingers metacarpophalangeal joints was excellent and good in 37 of the 39 patients without statistic association in relation to the muscle used. The flexor muscular strength of wrist after surgery decreased at grade 3 in 11 of the 12 patients in which we used the anterior cubital one unlike those used the palmaris major where the strength was of grade 4 in 17 of the 27 patients. The more frequent complication was the wrist radial deviation present in 4 patients in which we used the anterior cubital one. CONCLUSIONS: The palmaris major muscle is the more recommended alternative to restore the fingers extension in radial nerve paralyses

Título: Estudo comparativo experimental da injeção perineural do álcool benzílico 0, 75 e do álcool etílico absoluto nos nervos palmares de eqüinos / Experimental comparative study of perineural injection of benzyl alcohol 0, 75 and absolute ethyl alcohol in equine palmar nerves

Idioma: pt.
Resumo: Foi estudada a neurólise química dos nervos Palmares em 10 eqüinos. Usando-se uma ferradura especial para induzir claudicação, a locomoção avaliada ao passo e trote e os graus foram registrados antes e após a injeção perineural do álcool benzílico 0,75% (Grupo A) e o álcool etílico absoluto (Grupo B). Os testes mostraram que ambos os neurolíticos dessensibilizaram completamente a sola dos animais a partir de 30 dias, assim permanecendo até o 150º dia nos animais do Grupo A, quando ocorreu retorno progressivo da sensibilidade. Jáno Grupo B, aos 180 dias, a sensibilidade permanecia ausente. A análise histopatológica revelou que nos nervos infiltrados com álcool benzílico 0,75% prevaleceram lesões próprias de axonotemese,sugerindo tendência de regeneração e restabelecimento da condução nervosa, enquanto que nos nervos infiltrados com álcool etílico absoluto, prevaleceram lesões simuladoras de neurotemese, com degeneração nervosa permanente. Concluiu-se que os álcoois utilizados foram eficientes bloqueadores temporários ou permanentes dos nervos Palmares em eqüinos.

The clinical and histopathological effects of two alcoholic neurolytics were studied in horses. Normal horses were shod with a designed shoe adaptted with 5 screws to produce solar pain. After gait and lameness score analysis, the palmar nerve of 5 horses was injected with 5 ml of 0,75% benzyl alcohol (Group A) and 5 horses were injected with 5 ml of absolute ethyl alcohol (Group B). The animals were submitted to regular lameness evaluation and solar sensibility tests during next six months. The solar sensitivity returned 5 months latter in the group injected with benzyl alcohol 0,75%, while in the group injected with absolute ethyl alcohol, the sole was still desensitized 6 months latter. The histopathological findings showed that the nerve injected with benzyl alcohol 0,75%, resulted inaxonotmesis, characterized by axonal nerve degeneration, with possibilities for the nerve conduction recovery. The perineural injectionof ethyl alcohol absolute, resulted in neurotmesis with difficult nerve regeneration. It was concluded that chemical neurolysis with alcoholis an option for temporary or permanent nerve blocks in horses.
