Texto completoLas fracturas abiertas (FA) suponen un reto para el cirujano ortopédico, dado que se asocian a una alta tasa de infección y de pseudoartrosis. Se han desarrollado múltiples clasificaciones para las FA siendo la clasificación de Gustilo la más universalmente aceptada. Estas clasificaciones proporcionan una orientación en el tratamiento y un pronóstico basándose en criterios clínicos sujetos a una inherente variabilidad interobservador. Si bien la respuesta de fase aguda (RFA) ha sido bien estudiada en pacientes politraumátícos, existen pocos estudios a este respecto en FA. El presente es un estudio prospectivo sobre una cohorte de pacientes con fractura abierta de huesos largos, realizado con el fin de determinar si la RFA correlacionaba con los principales tipos de la clasificación de Gustilo y determinar la utilidad de los reactantes de fase aguda en la predicción de complicaciones y/o del resultado funcional a largo plazo.
MATERIAL Y MÉTODOS
Se trata de un estudio prospectivo, observacional, de un periodo de 15 meses, comprendido entre febrero de 2001 y mayo de 2003. Se incluyeron en el estudio aquellos pacientes esqueléticamente maduros, con fractura abierta de hueso largo, tratados dentro de las 6 primeras horas tras el accidente. Se excluyeron a los pacientes con antecedentes de infección activa, neoplasia o intervención quirúrgica en los 3 meses anteriores. Se excluyeron del estudio los pacientes con enfermedades previas con repercusión sobre la respuesta inmunitaria y/o inflamatoria. Se incluyeron un total de 64 pacientes con 69 FA con un Injury Severity Score (ISS) medio de 10,2. Se determinó la proteína C-reactiva, interleukina 6 (IL-6) y creatínquinasa (CK) el tercer día postoperatorio y se efectuó un seguimiento hasta la consolidación de la fractura registrándose posibles complicaciones. Así mismo se realizó un seguimiento mediante entrevista telefónica, con un mínimo de cuatro años tras la FA, mediante el cuestionario SF-36.
RESULTADOS
Las concentraciones séricas de PCR, IL-6 y CK el tercer día postoperatorio de una FA de hueso largo, no correlacionaron con la clasificación de Gustilo en sus tres tipos principales (p <0.05). La media de las concentraciones de PCR, CK e IL-6 el tercer día postoperatorio no presentó diferencias significativas entre los pacientes que presentaron complicaciones en general, infección y retardo de consolidación o pseudoartrosis, respecto a los pacientes que tuvieron una recuperación sin complicaciones (p>0,05). La mediana del parámetro CK de la presente serie fue de 550 U/L y un total de 21 pacientes (30,4%) presentaron niveles de CK superiores a 1000 U/L. Los resultados en la escala SF-36 no se relacionaron con las concentraciones de PCR, CK e IL-6 el tercer día postoperatorio (p>0,05). Como conclusión, la presente serie muestra que la clasificación de Gustilo no correlaciona con la respuesta de fase aguda tras una FA. Los reactantes de fase aguda no mostraron utilidad para la predicción de complicaciones o de un mejor o peor resultado funcional. De forma interesante, la incidencia de rabdomiolisis fue elevada en esta serie. A pesar de que consideramos necesarios más estudios para corroborar este hallazgo, recomendamos la determinación sistemática de CK en todos los pacientes afectos de FA con el fin de diagnosticar y tratar de forma precoz una eventual rabdomiolisis.

Texto completoINTRODUCTION Pseudoarthrosis or non union is a complication wich incidence is estimated around 5-10% of fractures. Its frequently located in diaphysis of long bones. It is a complication that requires important surgical procedures and a worrying problem in orthopedic and trauma surgery actually. The discovery of a molecule or biomarker to detect those patients at risk of develope a delayed bone healing or non union would help us to establish special measures for their treatment.earlier. MATERIAL AND METHODS We propose a prospective exploratory pilot study that analyzes a cohort of 20 patients diagnosed of non-hypertrophic non-union of long bones undergoing surgical treatment consisting in autologus bone graft +/- re osteosynthesis. These patients were followed for 12 months. Plasma blood samples were obtained to determine Tranforming Growth Factor B1 and B2 (TGF-B1, TGF-B2) at inclusion, at week, 2 weeks, 1 month, 2 months, 3 months, 6 months and 12 months after surgery. Radiological bone healing was evaluated by the Tomographic Union Score (TUS). RESULTS 20 patients were included, 17 were analyzed finally. 9 healed versus 8 that did not heal. The mean values of TGF-B1 at inclusión time point were: 26,702.4 +/- 14537 pg / ml. For TGF-B2: 307.8 +/- 83.1 pg / ml. Statistically significant differences were found between the bone healing group and the non-union group at 12 months for TGF-B1 (p 0.005). No significant differences were found between the two groups for TGF-B2. CONCLUSIONS TGF-B1 can be a serological marker of bone healing although we can not say that it is a biomarker that allows early detection of delayed unión or non unión in base of our results. The same conclusion would be applicable to TGF-B2.

Texto completoIn Rehabilitation Medicine, therapeutic application of vibration energy in specific clinical treatments and in sport rehabilitation is being affirmed more and more. Vibration exposure can have positive or negative effects on the human body, depending on the features and time of the characterizing wave. Short periods of vibration exposure and specific frequency values can determine positive adjustments of human body. Human body doesn’t vibrate like a unique body, but every element regarding its own resonance frequency can cause an amplification or attenuation of the vibrations applied. This is the reason why vibration application mechanisms are crucial: if applied in non specific way, Whole Body Vibration (WBV) treatments could have non positive effects. In order to focus the effect of vibration in the specific treatment area, local vibrations (LV) have been introduced in rehabilitation medicine. The initial aim of the present study was to translate the medical necessity of applying local vibration in clinical treatments into scientific-engineering language, producing a design solution. In collaboration with Boscosystem Company, a manufacturer of rehabilitation medicine and sport training devices, we have produced a specific prototype for LV application on human body. The device is user friendly, “auto-applicable” to the patient, it preserves clinical operator from vibration stress and it makes LV applications ergonomic. Then, we have tested our prototype, verifying that the vibration produced by it and applied on human body has objectively detectable effects, analyzing the behaviour of muscles in rest time and under vibration energy, by using surface electromyography, obtaining a greater response in the second scenary. Subsequently, a real clinical inquiry was made about the device effectiveness and its clinical use on patients. To achieve this goal, in collaboration with the Company Program of Physical Medicine and Day-Hospital Rehabilitation of Policlinico Tor Vergata in Rome, we have applied therapeutic exercise by vibration (TEV) produced by our device on a male patient with a non-union right tibial fracture. In itinere radiological images and Bone Mass Index analysis allow us to state that TEV, made by using our device, contributes decisively to the therapy of pathologies concerning disorders of bone callous forming, resolving the consolidation delay, reducing patient healing time; moreover it isn’t negligible the improvement induced on the patient, as far as paraesthetic symptomatology and reduction of perilesion edema are concerned. The next target of our study was the inquiry of TEV metabolic effects on the application muscle. So, we have used a Tissue Oximeter installed at Fatebenefratelli Isola Tiberina Hospital in Rome, that is able to detect Hb and HbO2 concentration trend, by using NIRS (Near InfraRed Spectroscopy). By making measurements during TEV application, it was possible to obtain information about metabolic activity in the treated area (biceps in our case). By analyzing Hb and HbO2 trends, we have shown a variation of total Hemoglobine, of oxygenated and non-oxygenated Hemoglobine and of oxygen saturation: in particular, we have shown an increase of oxygenated Hemoglobine. More measurements revealed us that, although Hemoglobine concentration increase could be partially caused by temperature rise, Local Vibrations themselves induce sensible variations.

Texto completoFemoral diaphyseal and supracondylar fractures are very incapacitating problems generally caused by high-energy traumas. Many complications can follow these lesions, but the association of pseudarthrosis with knee stiffness is among the most difficult ones to deal with. Nowadays, there is still a generally accepted approach, which gives priority to the pseudarthrosis treatment before knee blockage release. A simultaneous treatment of both, the fracture nonunion and the knee stiffness, would allow resolution of the problem in a single surgical procedure. Bending of the knee joint would improve the consolidation process and a single admission would decrease patient anxiety. This approach (quadricepsplasty + osteoperiosteal decortication + bone autografting + knee movement recovery), though it may increase tissue handling, blood loss and postoperative morbidity was proposed and it has been attempted in this service (HCPA) since 1990. A total of 12 consecutive patients (six men, six female; mean (sd) age of 30 (15) years; ranging from 22 to 65 years) were submitted to the combined procedure. The average (sd) time since onset of the orthopedic problem was 16 (6) months (range: 10 to 32 months) and the majority of the patients have already undergone surgical treatment. The average (sd) extent of movement was improved from 10o (9o) to 112o (13o) postoperatively. Not only all patients healed the fracture but also have obtained a statistically significant improvement in the extent of movement (Student t=31; P≤0.0001). However, thisimprovement was significantly greater in those patients with less than 16 months since disease onset than those over 16 months (Student t=2.71; P=0.02). This improvement was inversely correlated with time of clinical evolution since disease onset (Pearson correlation=-0,672; P=0,017). Postoperative course was uneventful and no death or severe complication occurred in this series. According to these findings, both purposes, the simultaneous treatment of the femoral pseudarthrosis and knee blockage was successfully achieved and therefore, if a combined approach as earlier as possible is established a better outcome should be expected.

Resumo: Objetivo: Realizar exames de imagem pré-operatórios, verificar a vascularização do segmento proximal do escafoide no intraoperatório e estabelecer correlações diagnósticas destes com o exame anatomopatológico. Justificativa: O diagnóstico pré-operatório do estado vascular do segmento proximal do escafoide é importante para o planejamento e direcionamento da escolha da técnica cirúrgica a ser utilizada. Métodos: Estudo experimental, prospectivo, caracterizado por ensaio não controlado. Os pacientes foram avaliados em relação à necrose do segmento proximal do escafoide em exames pré-operatórios (radiografia, tomografia computadorizada e ressonância nuclear magnética) e, no intraoperatório, no qual a condição vascular do segmento proximal do escafoide foi avaliada após sua perfuração, que demonstrou a presença ou não de sangramento. A ausência de sangramento estabelece como condição um segmento de necrose avascular ou esclerótico. Foi colhido material do segmento proximal e enviado para exame anatomopatológico, e os achados foram classificados em quatro tipos principais: viabilidade óssea, grau intermediário com maior ou menor viabilidade óssea e necrose completa. Foi utilizado o teste de qui-quadrado para testar a associação entre os achados dos exames de imagem e exame intraoperatório quando comparados com o exame de anatomopatológico. Resultados: Foram avaliados 19 pacientes do gênero masculino com diagnóstico de pseudoartrose do escafoide. Os resultados demonstraram que existe associação significativa entre a alteração radiográfica e a necrose óssea p<0,05 (0,026). A tomografia não apresentou associação significativa com o diagnóstico anatomopatológico da necrose do osso escafoide p>0,05 (0,125). A ressonância nuclear magnética mostrou que o hipossinal marcado em T1 apresentou correlação significativa com o diagnóstico anatomopatológico de necrose no segmento proximal do escafoide em todos os pacientes p<0,05 (0,002). Em 90% dos ossos considerados escleróticos na avaliação intraoperatória a necrose foi confirmada pelo exame anatomopatológico, e a associação foi significativa p<0,05 (0,003). Conclusão: Na pseudoartrose do escafoide, imagens de ressonância nuclear magnética com hipossinal de baixa intensidade marcado em T1 e ausência de sangramento no intraoperatório são fortes indicativos de necroseOsteonecrose do segmento proximal
Abstract: Background: The purpose of this study was to correlate the preoperative imaging, vascularity of the proximal pole, and histology of the proximal pole bone of established scaphoid fracture nonunions. Methods: This was a prospective observational study. Patients were evaluated preoperatively for necrosis of the proximal scaphoid fragment by radiography, computed tomography (CT) and magnetic resonance imaging (MRI). Vascular status of the proximal scaphoid was determined intraoperatively, demonstrating the presence or absence of puncate bone bleeding. Samples were harvested from the proximal scaphoid fragment and sent for pathological examination. We determined the association between the imaging and intraoperative examination and histological findings. Results: We evaluated 19 male patients diagnosed with scaphoid nonunion. CT evaluation showed no correlation to scaphoid proximal fragment necrosis. MRI showed a marked low signal intensity on T1-weighted, and the diagnosis of necrosis in the proximal scaphoid fragment was confirmed by the histology in all patients. Intraoperative assessment showed that 90% of bones had absence of intraoperative puncate bone bleeding, which was confirmed as necrosis by microscopic examination. Correlation between preoperative imaging, intraoperative findings and pathology was found in 41% of cases, with 26% for bone necrosis and 15% for viable bone. Conclusions: In scaphoid nonunion MRI images with marked low signal intensity on T1-weighted and the absence of intraoperative puncate bone bleeding are strong indicatives of osteonecrosis of the proximal fragment

Texto completoThe nonunion fracture is a relatively frequent complication in both human and veterinary medicine. Among their types, the atrophic nonunion fracture is usually the most difficult to treat and the elective treatment is surgery. In order to search for alternative therapeutic approach, the present study aimed to analyze the morphological changes induced by the use of nandrolone decanoate in experimental nonunion fracture with vascular deficit in the rat model. Ten adult Wistar rats (Rattus norvegicus) were divided into two groups, control (GC) and nandrolone decanoate (GNan). Surgical protocols were developed to promote fracture nonunion in the left femur diaphysis with vascular deficit by removing the periosteum and endosteum and isolating the fracture site using a latex artifact. After the establishment of the nonunion fracture, the GNan was treated with nandrolone decanoate (1.5mg/kg IM, once a week, during 4 weeks). Periodical radiological examinations were performed. In addition, anatomopathological evaluation, scanning electron microscopy, computed micro-tomography and optical microscopy techniques were performed. The results showed that the surgical protocols to establish the nonunion fracture were efficient and allowed qualitative and quantitative evaluation of bone growth. Besides, the nandrolone decanoate promoted the bone regeneration at the nonunion fracture site by raising the osteblastic activity and reducing the osteclastic activity. The percentage of collagen analysis did not reveal significant differences between GC and GNan. This guarantees some quality for the regenerated bone. Due to the economical viability of the use of nandrolone decanoate use, new advanced studies are recommended to prove the therapeutic potential of that anabolic steroid for the treatment of atrophic nonunion fracture in humans and other animals

Texto completoLa pseudoartrosis es una alteración en el normal proceso de la consolidación ósea que se traduce clínicamente por dolor y persistencia del foco de la fractura con movilidad y desviación del los fragmentos. Es la principal complicación de las fracturas, especialmente en los huesos largos, afectando al 10% de las mismas. El tratamiento de las pseudoartrosis combina diferentes técnicas incruentas con éxito dispar e inconvenientes. Las ondas de choque extracorpóreas son ultrasonidos de alta energía, originados en nuestro caso a través de un generador electromagnético, capaces de producir efecto físicos y biológicos en los huesos, mediante el efecto Hopkins y el fenómeno de cavitación, induciendo una hemorragia subperiostal que estimula el crecimiento óseo de novo. En el presente trabajo se trata de medir la eficacia de las ondas de choque extracorpóreas en el tratamiento de las pseudoartrosis establecidas de los huesos largos de las extremidades inferiores, a través de una valoración clínica y radiológica.
