ABSTRACT

ABSTRACT Purpose: This study was conducted to further define the specific clinical characteristics of patients with Brown syndrome and evaluate the outcomes of superior oblique tenotomy in its surgical management. Methods: A retrospective analysis of the medical charts of 45 patients with Brown syndrome was performed, which revealed that 11 patients underwent superior oblique tenotomy due to abnormal head posture and/or hypotropia and 1 patient underwent bilateral superior oblique tendon elongation with a silicone band due to abnormal head posture. In the last patient, silicone bands were removed at the postoperative 3rd month due to the lack of improvement in the abnormal head posture and the limitation of elevation in adduction. Simultaneous horizontal rectus muscle surgery was performed in four patients. Results: There was a predominance of female gender, right eye, congenital form, unilaterality, A-pattern, and an abnormal head posture type with a combination of chin up and head tilting. Bilateral form was observed only in female patients. Amblyopia was detected in two patients. Among patients aged >5 years, 40% had reduced stereopsis. Abnormal head posture was found in 60% of patients. More than half of them were diagnosed with a vertical and/or horizontal deviation. Tenotomy procedure eliminated the abnormal head posture in all patients and significantly improved the mean limitation of elevation in adduction and hypotropia (p=0.001, p=0.012). Two patients developed inferior oblique overaction in the operated eye. There was complete spontaneous resolution in two patients. Conclusions: The clinical features of patients with Brown syndrome in our study are considerably consistent with those of previous reports. The present study demonstrated the effectiveness of superior oblique tenotomy with less overcorrection in the surgical treatment of Brown syndrome.(AU)


RESUMO Objetivo: Definir mais detalhadamente as características clínicas específicas de pacientes com síndrome de Brown e avaliar os resultados da tenectomia do músculo oblíquo superior no manejo cirúrgico da síndrome de Brown. Métodos: Prontuários de 45 pacientes com síndrome de Brown foram analisados retrospectivamente. Onze pacientes submetidos à tenectomia do músculo oblíquo superior devido a postura anormal da cabeça ou a hipotropia e um paciente submetido ao alongamento bilateral do tendão do oblíquo superior com uma faixa de silicone devido a postura anormal da cabeça. Neste último paciente, a faixa de silicone foi removida no terceiro mês pós-operatório devido à ausência de melhora na postura anormal da cabeça e à limitação da elevação em adução. Quatro pacientes submeteram-se simultaneamente à cirurgia do músculo reto horizontal. Resultados: Houve predominância de sexo feminino, olho direito, forma congênita, acometimento unilateral, padrão em "A" e um tipo de postura anormal da cabeça combinando queixo elevado e inclinação da cabeça. A forma bilateral foi vista apenas em pacientes do sexo feminino. Foi constatada ambliopia em 2 pacientes. Dentre os pacientes acima de 5 anos de idade, 40% tinham estereopsia reduzida. Postura anormal da cabeça estava presente em 60% dos pacientes. Mais da metade dos pacientes foi diagnosticada com um desvio vertical, horizontal ou ambos. O procedimento de tenectomia eliminou a postura anormal da cabeça em todos os pacientes e melhorou significativamente a limitação média da elevação em adução e a hipotropia (p=0,001 e p=0,012). Dois pacientes desenvolveram hiperação do músculo oblíquo inferior no olho operado. Resolução completa ocorreu espontaneamente em 2 pacientes. Conclusões: O quadro clínico dos pacientes com síndrome de Brown no nosso estudo é bastante consistente com os relatos iniciais na literatura. Este estudo mostrou a eficácia da tenectomia do oblíquo superior, com menor hipercorreção no tratamento cirúrgico da síndrome de Brown.(AU)

ABSTRACT

OBJETIVO: Analisar as características de tendões de Aquiles de ratos após indução de processo inflamatório localizado na pata. MÉTODOS: Foram utilizados três grupos experimentais: grupo inflamado com carragenina na pata de rato (G1); grupo salina (G2) e grupo controle (G3). Após 4 horas os animais foram eutanaziados e o tendão de Aquiles foi removido. RESULTADOS:Não foram observadas diferenças significativas nas análises de proteínas não colagênicas, glicosaminoglicanos e hidroxiprolina, mas uma tendência a diminuição foi verificada em G1. Em organização de moléculas de colágeno não foram observadas diferenças entre os grupos. Com respeito à atividade de MMPs, foi observada uma presença maior da isoforma ativa da MMP-2 em G1, sugerindo que a remodelação do tecido está ocorrendo. CONCLUSÃO: Desta forma, nós concluímos que o processo inflamatório desencadeado em pata de rato pode afetar o remodelamento de tendões situados próximo ao local inflamado.

OBJECTIVE: To analyze the characteristics of the Achilles tendon of rats after induction of localized inflammation in the rat paw. METHODS: In our study three groups were used: inflamed group with carrageenan in rat paw (G1); saline group (G2) and control group (G3). After 4 hours the animals were euthanized and the Achilles tendon removed. RESULTS: No significant differences were observed in the analysis of non-collagenous proteins, glycosaminoglycans and hydroxyproline in the groups but a tendency of reduction was verified in G1. About the organization of collagen molecules, no differences were observed between groups. With respect to MMPs activity, a stronger presence of the active isoform of MMP-2 in G1 was observed, suggesting that the remodeling was occurring. CONCLUSION: Thus, we conclude that the inflammatory process in rat paw may affect the remodeling of tendons located near the inflamed site.

ABSTRACT

PURPOSE: To investigate the degree of reunion in rabbit eyes of the superior oblique tendon after several surgical weakening procedures. METHODS: A total of 32 rabbits (64 eyes) were used in this study. The rabbits were randomly assigned to four groups, eight rabbits (16 eyes) in the tenotomy group, eight rabbits (16 eyes) in the tenectomy group, eight rabbits (16 eyes) in the disinsertion group and eight rabbits (16 eyes) in the recession group. The degree of reunion or reattachment of the superior oblique tendon on the globe were examined on four eyes in each group at postoperative weeks two, four, six and eight. RESULTS: At eight weeks, the newly created insertion site remained at the same site in all eyes in the recession group, and the distal end of the superior oblique tendon was reattached at the medial border of the superior rectus muscle in all four eyes in the tenotomy and disinsertion groups, and in three of four eyes in the tenectomy group. CONCLUSIONS: From this experimental study, it was speculated that superior oblique recession is more effective than other superior oblique weakening procedures. This result could be helpful in the prediction of time of recurrence for superior oblique overaction after superior oblique weakening procedures.

ABSTRACT

The critical step in dynamic claw-finger correction procedures is adjustment of tension on the tendon slips which are being sutured at the new insertion sites to correct finger-clawing. Several methods to balance and adjust the tension have been described ever since these procedures have been in use. Ultimately it is the experience of the operating surgeon that helps to decide as to the tension that is to be kept on each slip so that maximum deformity correction is obtained without compromising the functional capabilities of the hand. An attempt has been made to describe this "experience" in words so that the surgeons who perform these corrective surgical procedures for the first time have some criteria to guide them.

ABSTRACT

Objetivos: Analisar o exame ultra-sonográfico no diagnóstico da LER/DORT, através da correlação entre os aspectos clínicos com os achados ultra-sonográficos (avaliação qualitativa) de ombros e punhos e análise das dimensões do túnel do carpo e nervo mediano nos indivíduos sintomáticos e assintomáticos. Métodos: Realizados exames ultra-sonográficos com transdutor linear de alta resolução (10 MHz) de ombros e punhos em 56 indivíduos, todos do sexo feminino, montadores de velocímetros, sendo 41 sintomáticos e afastados do trabalho com diagnóstico de LER/DORT e 15 assintomáticos. A técnica utilizada segue a estabelecida na literatura. Foram correlacionados os achados ultra-sonográficos com os achados de exame físico de acordo com significância clínica que cada teste realizado poderia indicar (quadros 1 e 2). As medidas do túnel do carpo e nervo mediano realizadas em diversos planos (pisiforme e hamato) e a área calculada através do método indireto, considerando o túnel do carpo e nervo mediano com forma geométrica ovóide. Os achados foram submetidos à avaliação estatística. Resultados: Os principais achados de exame físico nos 41 indivíduos sintomáticos foram: dor a palpação da cintura escapular, teste do pinçamento subacromial positivo, dor a palpação no punho e testes de Phalen e Finkelstein positivos. Dos 82 exames de ultra-som nos indivíduos sintomáticos: 29 exames de ombros (35,4 por cento) e 17 exames de punhos (20,7 por cento) mostraram-se alterados. As principais foram: Líquido/bursite subacromial subdeltoídea, líquido na bainha do tendão da cabeça longa do bíceps, nervo mediano espessado e líquido na bainha dos tendões flexores. Dos 30 exames de ultra-som nos indivíduos assintomáticos 10 exames (33,3 por cento) mostraram alguma alteração. O achado mais freqüente foi: tendinopatia calcária em 8 casos, 66,7 por cento do total dos achados encontrados. Na correlação entre o exame físico e achados ultra-sonográficos no ombro, não houve concordância significativa para dor a palpação e pinçamento subacromial; houve concordância significativa para a negatividade entre lesão do manguito rotador e do tendão da cabeça longa do bíceps. Não houve concordância significativa entre o exame físico e achados ultra-sonográficos no punho. Não houve diferença estatisticamente significante entre as medidas do túnel do carpo e nervo mediano para os indivíduos sintomáticos e assintomáticos. Conclusões: O exame ultra-sonográfico não mostrou correlação significativa com os parâmetros clínicos, em pacientes com LER/DORT, porém pode confirmar a ausência de lesão tecidual específica principalmente nos ombros devido à correlação estatística para a negatividade entre os teste do manguito e tendão da cabeça longa do bíceps. Não houve diferença nas dimensões do túnel do carpa e nervo mediano entre os indivíduos sintomáticos e assintomáticos.

ABSTRACT

The study was aimed at comparing the ultimate load bearing capabilities between normal patellar tendons (control group) and tendons after central one-third removal (removal group). Eleven fresh Thai cadavers provided study specimens. The average age of the cadavers was 24.86 +/- 7.13 years. Five tendons were used as control specimens and another six tendons underwent central one-third removal. The Instron 5583 testing machine and Cooper's technique of measurements were used to test the ultimate load. Rate of elongation of tendon was set at 500 mm/sec. The results showed that the removal group cross-sectional area was 48.67 mm2 or 49.64 per cent of the control group (98.04 mm2). The mean ultimate load of the control group was 4,365.59 N. The mean ultimate load of the removal group was 2,226.58 N or about 51 per cent. The energy level to breaking point in the control group was 72.17 J and 32.58 (45.14%) in the removal group. The average width of the central one-third portion was measured at 8.68 +/- 0.56 cm. Generally in a clinical situation, when the ultimate load is reduced to about half in the donor knee, care must be taken before allowing full weight to bear. Caution should also be emphasized in cases where a routinely 10 mm wide graft has been taken, as the donor tendon may be weakened by more than half and may rupture prematurely.

ABSTRACT

A retrospective study was carried out to compare the effectiveness of different muscles as motors in modified lasso procedures for correction of finger clawing in leprosy. It was observed that palmaris longus and extensor carpi radialis longus were more suitable than the flexor digitorum superficialis. In some patients, removal of superficialis is associated with complications which could not be predicted before surgery. Extensor carpi radialis longus has advantages over palmaris longus in selected cases.

ABSTRACT

Skin and tendon samples of male albino rat taken for analysis, on the 120th day of smoking showed that, compared to controls, the cigarette smoke exposed group showed an increase in tensile strength of both skin and tendon while extensibility of skin remained the same and that of the tendon increased. Thermal behaviour such as isometric tension and temperature at isometric tension increased in rat skin, while in tendon only isomeric tension increased. Shrinkage temperature of skin and tendon has showed no alteration in cigarette smoke exposed rats.

ABSTRACT

El tratamiento del síndrome subacromial ha tenido diferentes modalidades y no es hasta los últimos años cuando realmente se le ha dado más valor a la acromioplastia. La artroscopia, la tomografía axial computarizada, la resonancia magnética y el ultrasonido, son de inigualable valor para establecer el diagnóstico en más de 90 por ciento de los casos. Además, el tratamiento por artroscopia inicia su verdadera validez en este síndrome con una recuperación funcional importante. Se hizo la revisión de 184 casos, entre los que predominó el sexo femenino con 56.52 por ciento. Los recursos diagnósticos fueron placa radiográfica simple, artrografía, ultrasonido y artroscopia. Se observó que la artrografía y el ultrasonido y artroscopia. Se observó que la artrografía y el ultrasinido son confiables en el 80 por ciento, mientras que la artroscopia lo fue en el 62.50 por ciento. Los resultados con acromioplastia fueron buenos en el 84.87 por ciento de los casos regulares en el 14.13 y malos en el 1.09. Se concluye que el ultrasonido y la artrografía son recursos básicos para el diagnóstico, que la artrografía debe ser desechada por ser un método invasivo. Que los resultados son satisfactorios en el 84.78 por ciento y que las complicaciones son mínimas.
