RESUMO

La pseudoartrosis es una complicación caracterizada por la ausencia de consolidación del hueso a los 9 meses desde el inicio de la fractura, con falta de progresión radiológica los últimos 3 meses, siendo sus principales causas el exceso de movimiento en el foco de fractura y una insuficiente vascularización. A pesar de no tratarse de una complicación frecuente, los huesos del antebrazo ocupan el 4.º puesto en incidencia de presentación. El manejo anestésico de la patología quirúrgica del miembro superior se realiza generalmente en régimen ambulatorio con técnicas de anestesia regional guiadas por ecografía. Estas técnicas tienen una doble función: anestesia durante el propio acto quirúrgico con una mínima variabilidad sobre el estado basal del paciente y analgesia en el postoperatorio inmediato, permitiendo de esta manera el alta a domicilio de forma más segura y precoz. Presentamos el caso de un varón de 34 años, con desarrollo de pseudoartrosis atrófica tras fractura diafisaria de radio, en el que se realiza injerto óseo de cresta ilíaca y aspirado de células madre como estímulo de la osteogénesis.(AU)


Pseudarthrosis is a complication characterised by the absence of bone healing 9 months after the onset of the fracture, with a lack of radiological progressionin the last 3 months, and its main causes are excessive movement at the fracture site and insufficient vascularisation. Despite not being a frequent complica-tion, the bones of the forearm occupy the fourth place in incidence of presentation. The anaesthetic management of surgical pathology of the upper limb isgenerally performed on an outpatient basis with regional anaesthesia techniques guided by ultrasound. These techniques have a dual function: anaesthesiaduring the surgical act with minimal variability over the patient’s baseline condition and analgesia in the immediate postoperative period, thus allowing forsafer and earlier discharge home. We present the case of a 34-year-old male with diagnosis of atrophic pseudarthrosis following a diaphyseal fracture of theradius, in whom iliac crest bone grafting and stem cell aspiration were performed to stimulate osteogenesis.(AU)

RESUMO

Objetivo: Comparar in vivo la capacidad de formación ósea de dos tipos de biomateriales diseñados como sustitutivos óseos respecto a autoinjerto de cresta iliaca, uno basado en carbonatohidroxiapatita y otro en vidrio mesoporoso bioactivo. Material y método: Estudio experimental compuesto por 14 conejos de Nueva Zelanda hembras adultas donde se realizó un defecto crítico en hueso radio. La muestra fue dividida en cuatro grupos: defecto sin material, con autoinjerto de cresta iliaca, con soporte de carbonatohidroxiapatita y con soporte de vidrio mesoporoso bioactivo. Se realizaron estudios seriados de radiología simple a las 2, 4, 6 y 12 semanas y estudio de micro-TC a eutanasia a las 6 y 12 semanas. Resultados: En el estudio de radiología simple, el grupo de autoinjerto mostró las mayores puntuaciones de formación ósea (7,5 puntos). Ambos grupos de biomateriales presentaron formación ósea similar (5,3 y 6 puntos, respectivamente) y mayor al defecto sin material (4 puntos), pero siempre menor que el grupo de autoinjerto. Los resultados del estudio de micro-TC mostraron el mayor volumen de hueso en el área de estudio en el grupo de autoinjerto. Los grupos con sustitutivos óseos presentaron mayor volumen de hueso que el grupo sin material, pero siempre menor que en el grupo de autoinjerto. Conclusiones: Ambos soportes parecen favorecer la formación ósea pero no son capaces de reproducir las características del autoinjerto. Por sus diferentes características macroscópicas cada uno podría ser adecuado para un tipo diferente de defecto.(AU)


Aim: Compare bone formation capacity in vivo of two types of biomaterials designed as bone substitutes with respect to iliac crest autograft, one based on carbonate hydroxyapatites and the other one on bioactive mesoporous glass. Materials and methods: Experimental study consisting on 14 adult female New Zeland rabbits where a critical defect was made in the rabbit radius bone. The sample was divided into four groups: defect without material, with iliac crest autograft, with carbonatehydroxyapatite support, and with bioactive mesoporous glass support. Serial X-ray studies were carried out at 2, 4, 6 and 12 weeks and a microCT study at euthanasia at 6 and 12 weeks. Results: In the X-ray study, autograft group showed the highest bone formation scores. Both groups of biomaterials presented bone formation similar and greater than the defect without material, but always less than in the autograft group. The results of the microCT study showed the largest bone volume in the study area in the autograft group. The groups with bone substitutes presented greater bone volume than the group without material but always less than in the autograft group. Conclusion: Both supports seem to promote bone formation but are not capable of reproducing the characteristics of autograft. Due to their different macroscopic characteristics, each one could be suitable for a different type of defect.(AU)

RESUMO

OBJETIVO: Pese a la alta frecuencia de complicaciones tras la cistoprostatectomía, no ha sido descrita en la literatura médica una fístula que comunique arteria iliaca externa y ureteroileostomía. Presentamos un caso de hemorragia masiva a través de la ostomía de la ureteroileostomía Bricker debido a un aneurisma micótico de arteriailiaca externa fistulizado a la ureteroileostomía. MÉTODO: Paciente de 78 años intervenido de cistoprostatectomía laparoscópica con derivación Bricker debido aneoplasia vesical infiltrante. Durante el postoperatorio inmediato presentó diferentes complicaciones destacando la sepsis debido a una colección pélvica. Acudió a urgencias por hemorragia masiva a través de ostomía de Bricker siendo diagnosticado mediante TC de sangrado activo desde arteria iliaca externa a interior de ureteroileostomía. Ante los hallazgos se decidió cirugía abierta urgente donde se apreció aneurisma con orificio fistuloso comunicando cara medial de arteria iliaca externa con asa de Bricker de medio centímetro de diámetro. Fue necesario ligar dos centímetros de arteria iliaca externa, realizar bypass fémoro-femoral, cierre de orificio en asa de Bricker y ureterostomía cutánea derecha. RESULTADO: Durante el postoperatorio requirió terapia renal sustitutiva, drogas vaso activas y cuidados en reanimación tras lo cual presento mejoría clínica y analítica decidiéndose alta 11 días tras la intervención. CONCLUSIONES: La presencia de una fístula arterial no controlada supone actuar de manera urgente ante una patología como el aneurisma micótico que ya de por sí supone un reto. La sospecha clínica, la rapidez del diagnósticoy la habilidad quirúrgica suponen piezas clave para aumentar las posibilidades de supervivencia del paciente


OBJECTIVE: Despite the high frequency of complications after a radical cystoprostatectomy, the presence of a fistula that communicates the external iliac artery and the ureteroileostomy has not been described in the medical literature. We present the diagnosis and medical management of a massive hemorrhage through the Bricker 's ostomy due to an external iliac artery's mycotic aneurysm fistulized to the ureteroileostomy. METHOD: A 78 years old patient underwent laparoscopic radical cystoprostatectomy with Bricker-type urinary diversión due to muscle-invasive bladder cancer. During the immediate postoperative period he presented different complications including sepsis caused by a pelvic collection. Due to a massive hemorrhage through Bricker's ostomy he went to the emergency department where was diagnosed by CT of active bleeding from right external iliac artery to the interior of the ureteroileostomy. We decided to perform exploratory laparotomy showing an aneurysm with fistulous orifice communicating the medial external iliac artery to Bricker ureteroileostomy. A femoro-femoral bypass, ligation of two centimeters of the external iliac artery, closure of the Bricker's orifice and right cutaneous ureterostomy was needed. RESULTS: After the surgery, the patient required renal replacement therapy and vasoactive drugs. Discharge from the hospital was 11 days after the intervention. CONCLUSIONS: The presence of an uncontrolled arterial fistula implies urgent care in a pathology such as the mycotic aneurysm that already constitutes a challenge. Fast diagnosis and surgical skills are essential to increase patient's survival chances

RESUMO

The objective of this study was to determine sex differences in the anatomical relations between clinically relevant and palpable bony landmarks (anterior superior iliac spine, or ASIS), posterior superior iliac spine (PSIS), iliac tubercle and greater trochanter, and with the gluteal muscles and sciatic nerve. After dissection, distances along the iliac crest, angles and distances between bony landmarks, muscle thicknesses of gluteus maximus and gluteus medius, the fibre angles of gluteus maximus, and anatomical relations between the sciatic nerve and bony landmarks, were measured. In 23 cadavers (11 males; 12 females), iliac crest total length, distances between the greater trochanter, ASIS and iliac tubercle, and between the sciatic nerve and iliac crest, but only the angle at the PSIS between the iliac tubercle and greater trochanter, were significantly larger in males. Distances and angles reflecting horizontal measures, iliac crest proportions, and gluteus maximus fibres angles were not different between sexes. Gluteus maximus muscle fibre angles differed significantly along the sagittal plane and from medial to lateral. In conclusion, while males have a larger ilium and taller pelvis, there was no sex difference in pelvic width. Therefore, the female pelvis is shorter and relatively wider with respect to pelvic height, but is not absolutely wider than the male pelvis. This puts females at a greater risk of sciatic nerve injury with a dorsogluteal site injection. The angles of the gluteus maximus muscle fibres varied along their length and were not consistently 45o as commonly described

RESUMO

Introducción: El dolor en fosa ilíaca derecha es un motivo frecuente de consulta y el diagnóstico de apendicitis sigue siendo un reto. El Pediatric Appendicitis Score (PAS) estratifica el riesgo de padecer apendicitis, y la ecografía abdominal aporta información sin irradiación. Este estudio pretende correlacionar su puntuación y la ecografía con el despistaje de apendicitis y valorar su rendimiento. Pacientes y métodos: Estudio prospectivo de casos y controles, analítico, observacional y longitudinal. Se evaluó a los pacientes <15 años, atendidos por sospecha de apendicitis en urgencias de un centro de II nivel, durante 6 meses. Se analizaron los datos de forma univariante y bivariante, utilizando pruebas no paramétricas y paramétricas según la distribución. Resultados: Se incluyeron 68 pacientes con dolor en fosa ilíaca derecha: 26 apendicitis (casos) (38,2%) y 42 (61,7%) otros diagnósticos (controles). El PAS en apendicitis fue de 7,5±1,8 y en otros diagnósticos de 5,4±1,8 (p<0,01). Al 70,5% con PAS ≥4 se les realizó una ecografía (diagnósticas de apendicitis 58,1%, descartaron 25,6% y no concluyentes 16,3%). Se calculó la sensibilidad y especificidad por grupos de PAS solamente, e incluyendo la ecografía. El mejor resultado fue para PAS ≥4 con realización de ecografía con una sensibilidad 96,2%, especificidad 94,1%, VPP 96,1% y VPN 94,1%. Conclusiones: El PAS es una buena herramienta de cribado para el diagnóstico de apendicitis. La ecografía presenta un alto rendimiento para el diagnóstico de apendicitis. Este rendimiento mejora al realizarla en el grupo de pacientes con PAS ≥4


Introduction: Pain in the right iliac fossa is a frequent reason for consultation and the diagnosis of appendicitis remains a challenge. The Pediatric Appendicitis Score (PAS) stratifies the risk of suffering appendicitis, and abdominal ultrasound provides information without irradiation. This study aims to correlate the score and the ultrasound with the screening of appendicitis and evaluate its efficiency. Patients and methods: Prospective study of cases and controls, analytical, observational and longitudinal. Patients <15 years of age, treated for suspected appendicitis in the emergency department of a II level center, were evaluated for 6 months. The data were analyzed univariate and bivariate, using nonparametric and parametric tests according to the distribution. Results: 68 patients with pain in the right iliac fossa were included: 26 appendicitis (cases) (38.2%) and 42 (61.7%) other diagnoses (controls). The PAS in appendicitis was 7.5±1.8 and in other diagnoses 5.4±1.8 (p <0.01). At 70.5% with PAS ≥4 an ultrasound was performed (diagnosis of appendicitis 58.1%, discarded 25.6% and inconclusive 16.3%). Sensitivity and specificity were calculated by PAS groups only, and including ultrasound. The best result was for PAS ≥4 with ultrasound with a sensitivity of 96.2%, specificity 94.1%, PPV 96.1% and NPV 94.1%. Conclusions: PAS is a good screening tool for the diagnosis of appendicitis. Ultrasound presents a high efficiency for the diagnosis of appendicitis. This efficiency improves when performed in the group of patients with PAS ≥4

RESUMO

Background: Older alveolar cleft patients (>12 years old) often have wide bone defect as well as teeth loss, resulting in poor osseous healing with conventional alveolar bone grafting (ABG). In this study, we investigated a surgical technique of block iliac bone grafting for the alveolar cleft reconstruction and evaluated the clinical and radiological outcomes of these cleft patients. Material and Methods: Fifteen patients were included in this study. All cases received preoperative cone bean computed tomography (CBCT) scans for the alveolar cleft evaluation. Osseous outcomes of block iliac bone grafting were assessed at 1 week, 3- and 6-month postoperatively. Volume changes and bone resorption rates were calculated using the measurement modules of Simplant software. Bone samples from one patient undergoing dental implantation were assessed by micro-CT and histological examination. The morbidities of donor-site were analyzed by clinical examination and questionnaire survey. Results: The average age of the case series was 18.53±2.50 years. The intraoral incision of thirteen cases healed well. However, two cases had oronasal fistula and graft exposure at 1-week postoperatively. The results of follow-up CBCT scans showed significant resistance to radiation on both sides of the bone graft, suggesting a good osseous healing and new bone formation. The mean residual bone volume was 1.68±0.26 cm3 , 1.29±0.23 cm3 and 1.15±0.23 cm3 at 1-week, 3- and 6-month postoperatively. Correspondingly, the mean bone resorption rates in 3- and 6-month postoperative were 21.78±6.88% and 30.66±8.97%, respectively. From micro-CT and HE examinations, the block bone samples exhibited a cancellous structure in which mature bone trabecula and functional blood vessels appeared. The average scores of donor-site morbidities were drastically decreased at 3- and 6-month postoperatively compared with those at 1-week postoperatively. Conclusions: Our results demonstrated that block iliac bone grafting could achieve satisfying osseous outcomes in older alveolar cleft patients, and this technique provided favorable bony condition for further treatments, especially dental implantation (AU)

RESUMO

El sarcoma epitelioide representa menos del 1% de los sarcomas de partes blandas, posee una elevada capacidad para invadir los linfáticos regionales y alta tasa de recurrencias. Las formas clásicas se localizan preferentemente en la porción distal de las extremidades y afectan sobre todo a varones jóvenes, mientras que las formas proximales, además de características histológicas diferentes, tienden a situarse en el tronco, la pelvis y la raíz de las extremidades. El desarrollo intraóseo de este sarcoma es excepcional. En este artículo describimos a un paciente de 47 años que consultó por dolor en la región sacroilíaca derecha imitando una sacroilitis. La tomografía computarizada pélvica objetivó una lesión osteolítica en la región posterosuperior del ilíaco derecho, de la que se obtuvieron muestras mediante biopsia percutánea. Los hallazgos histológicos fueron típicos de sarcoma epitelioide clásico. En nuestro conocimiento, este es el segundo caso descrito en la literatura en que esta neoplasia se desarrolla primariamente en el tejido óseo (AU)


Epithelioid sarcoma represents less than 1% of soft tissue sarcomas and has a high recurrence rate and strong ability to invade the regional lymphatic pathways. Classic epithelioid sarcoma has a predilection for young men and usually affects the distal extremities, while the proximal-type is characterized by different histological features and most commonly occurs in the proximal part of the extremities, trunk and pelvis. Intraosseous tumor development is rare. We describe a 47 year old patient with sacroiliac pain mimicking sacroiliitis. A computed tomography of the pelvis showed a destructive intraosseous lesion of the upper- right iliac. Percutaneous biopsy of the lesion was obtained and histological findings were typical of classic epithelioid sarcoma. To our knowledge, this is the second case of intraosseous epithelioid sarcoma described in the medical literature (AU)

RESUMO

Introducción: La dismenorrea primaria (DP) es un desorden ginecológico común en mujeres en edad reproductiva. Se define como el conjunto de síntomas que preceden a la menstruación, siendo el más característico de ellos el dolor en la zona baja del abdomen seguido del dolor lumbo-pélvico. Objetivos: Valorar el efecto de la manipulación global de la pelvis (MGP) sobre el dolor lumbar en pacientes con DP a través de: (i) el dolor lumbo-pélvico percibido; (ii) el umbral del dolor a la presión (UDP) en las articulaciones sacroilíacas (ASIS); (iii) la respuesta endógena del cuerpo frente al dolor con la liberación de catecolaminas y serotonina. Material y Métodos: Estudio experimental, controlado, aleatorizado, doble ciego. Han participado 20 pacientes con DP, 10 formaron parte del Grupo Experimental (GE) y 10 del Grupo Control (GC). Se midió el dolor lumbo-pélvico con una escala visual analógica (EVA), el UDP con un dinamómetro digital y los niveles de catecolaminas/serotonina con una analítica sanguínea. Resultados: El GE obtuvo una mejoría significativa en el UDP de ambas ASIS (p=0.001), no así en el dolor lumbo-pélvico percibido (p=0.129). Asimismo, aumentaron los niveles de serotonina y dopamina en el GE aunque no de manera significativa (p=0.447) y (p=0.255) respectivamente, mientras que disminuyó la concentración en plasma de adrenalina (p=0.819) y noradrenalina (p=0.218). Conclusiones: La MGP mejora el UDP en ambas ASIS en pacientes con DP, no así el dolor lumbo-pélvico medido con EVA. La MGP también aumenta los niveles de serotonina, aunque no de manera significativa, mientras que no produce ningún cambio en los niveles plasmáticos de catecolaminas (AU)


Introduction: Primary Dysmenorrhea (PD) is a common gynaecological disorder in women of childbearing age. The most common premenstrual symptom is pain in the lower abdomen, followed by low back and pelvic pain. Objectives: We aim to assess the effect of global pelvic manipulation (GPM) on low back pain in subjects with PD through the evaluation of the: (i) self-perceived low back-pelvic pain; (ii) pressure pain threshold (PPT) in right and left sacroiliac joints (SIJ), and (iii) endogenous response of the organism to pain following catecholamines and serotonin release. Material and Methods: A randomized, double-blind, controlled clinical trial was performed to evaluated the efficacy of the GPM in the treatment of women with PD. Twenty patients (n=20) with PD were screened, ten (n=10) belonged to the control group (CG) and ten (n=10) to the experimental group (EG). The low back-pelvic pain was measured using Visual Analogue Scale (VAS) scores, the PPT was determined with a digital algometer, and a blood test was performed to determine catecholamines (adrenaline, noradrenalin, and dopamine) and serotonin levels. Results: A significant improvement of the PPT of both SIJ (p = 0.001) was observed in the EG, although there were no differences in the self-perceived low back-pelvic pain (p = 0.129). There was a nonstatistically significant increase in serotonin (p=0.447) and dopamine (p = 0.255) levels, as well as a nonsignificantly decrease in plasma levels of adrenaline (p = 0.819) and noradrenalin (p=0.218) in the EG. Conclusions: The bilateral GPM technique improves the PPT in both SIJ in patients with PD, but it does not affect the self-perceived low back-pelvic pain. The GPM also increases serotonin levels, but not significantly, although no changes are detected in the catecholamines plasma levels(AU)

RESUMO

Odontogenic fibromyxomas are benign odontogenic tumors of mesenchymal origin of rare presentation in the oralcavity, which exhibit locally aggressive behavior and are prone to local recurrence. The controversy has mainlybeen on therapeutic management with recommendations varying, depending on the clinical cases, from simplecurettage of lesion to segmental bone resection. We present a case report describing the reconstruction of an os-seous defect in the maxilla and the restoration with dental implants in a 32 year old female patient after radicalsurgical excision due to an odontogenic fibromyxoma with locally aggressive behavior. The primary reconstructionof maxillary discontinuity defect was carried out by an immediate non-vascularized cortico-cancellous iliaccrest graft. Using a computer-guided system for the implant treatment-planning, three dental implants were secondaryplaced in the bone graft by means of flapless implant surgery. The patient was subsequently restored withan implant-supported fixed prosthesis that has remained in continuous function for a period of three years. Thesurgical, reconstructive and restorative treatment sequence and techniques are discussed (AU)

RESUMO

Introducción: el colgajo de cresta ilíaca (CCI) es uno de los utilizados con mayor frecuencia en la reconstrucción facial. Su vascularización depende de los vasos circunflejos ilíacos profundos (ACIP, VCIP). Este trabajo describe, por primera vez, la posibilidad de doble irrigación de la isla cutánea del CCI incluyendo el sistema circunflejo ilíaco superficial para la reconstrucción de cabeza y cuello. Material y método: se diseccionaron 10 regiones inguinales de 5 cadáveres en el Departamento de Anatomía de la Facultad de Medicina Rovira i Virgili de Reus (Tarragona). En el periodo 2005-2007, 3 pacientes fueron intervenidos en el Servicio de Cirugía Maxilofacial del Hospital Joan XXIII de Tarragona, requiriendo un colgajo osteomiocutáneo microvascularizado de cresta ilíaca. Resultados: los 3 casos clínicos mostraron una evolución satisfactoria. Esta técnica proporciona una mayor vascularización del colgajo y una mayor disponibilidad tridimensional e implica menor morbilidad de la zona donante, ya que se necesita tallar menos cantidad de oblicuo pues la irrigación de los vasos perforantes no depende de la ACIP. Conclusiones: esta variación técnica del colgajo de cresta ilíaca puede sernos de gran utilidad en la reconstrucción de defectos complejos maxilofaciales a cambio de realizar una disección vascular y su anastomosis extra (AU)


Introduction. The iliac crest flap is commonly used in reconstructions of the head and neck. The vascularisation of this region depends on the deep circumflex iliac artery and vein(ACIP/VCIP). The present study describes for the first time, the simultaneous use of the deep and superficial circumflex iliac systems to obtain an iliac crest flap for head and neck reconstructions. Material and method: Ten inguinal regions were dissected in five cadavers in the Human Anatomy and Embryology Unit of the Faculty of Medicine of the Rovira i Virgili University. In the period 2005-2007, three patients required mandibular reconstruction with a microvascularisediliac crest osteocutaneous flap at the Maxillofacial Surgery Unit of the Joan XXIII University Hospital. Results: The 3 cases showed a favourable outcome. This “supercharging” variation guarantees the perfusion to the skin flap, provides a better three-dimensional arrangement of the soft tissue and lowers the morbidity at the donor site, as much less internal oblique muscle cuff is harvested Conclusions: This technique may be of great interest in the reconstruction of complex maxillofacial defects instead of having to carry out a vascular dissection and its extra anastomosis (AU)
