RESUMO
La osteomielitis crónica recurrente multifocal es un trastorno inflamatorio estéril en las extremidades. Afecta principalmente a niños simulando una osteomielitis infecciosa. Puede estar asociada a trastornos inflamatorios cutáneos y del tracto intestinal. Los niveles de reactantes de fase aguda están normales o levemente altos. Las radiografías muestran lesiones osteolíticas rodeadas por esclerosis, pero pueden ser normales al inicio de la enfermedad. Identificar las características propias de la enfermedad y descartar una etiología infecciosa permiten establecer un diagnóstico oportuno y ofrecer el manejo adecuado. Se presentan tres casos de esta patología. Un hombre de 24 años con síntomas inflamatorios persistentes y recidivantes en el tobillo derecho, de 8 años de evolución. Una niña de 11 años que acude reiterativamente por dolor en hemitórax, clavícula derecha y tobillo izquierdo, y una niña de 12 años con múltiples episodios breves de síntomas inflamatorios en ambos tobillos. Los tres casos, sin leucocitosis, reactantes de fase aguda levemente aumentados o negativos, con criterios mayores y menores de Jasson para diagnóstico de esta patología. Los cuadros mejoraron con antinflamatorios no esteroides. Es importante conocer esta rara entidad como posibilidad diagnóstica, pues un diagnóstico oportuno evita el uso innecesario de antibióticos y la resolución del cuadro se logra con antinflamatorios no esteroides, sin necesidad de procedimientos quirúrgicos que aumentan las comorbilidades.

Chronic recurrent multifocal osteomyelitis is a sterile inflammatory limb disorder. It mainly affects children simulating an infectious osteomyelitis. It may be associated with inflammatory skin and intestinal tract disorders. Acute phase reactant levels are normal or slightly high. X-rays show osteolytic injuries surrounded by sclerosis, which may be normal at the beginning of the disease. A timely diagnosis based on identifying the disease characteristics and ruling out an infectious etiology, allows to indicate the proper treatment. We present three patients with this pathology. A 24-year-old man with persistent and recurrent inflammatory symptoms in the right ankle, that evolved for 8 years. An 11-year-old girl who periodically attends due to pain in hemithorax, right clavicle and left ankle; and a 12-year-old girl with multiple brief episodes of inflammatory symptoms in both ankles. The three cases, without leukocytosis, acute phase reactants slightly increased or negative, with major and minor Jasson's diagnosis criteria for this pathology. These conditions improved with non-steroidal anti-inflammatory drugs. It is important to know this rare condition as a diagnostic possibility, as a timely diagnosis prevents unnecessary use of antibiotics and it may resolve with a simple therapy of non-steroidal anti-inflammatory drugs, without the need of surgical procedures that increase comorbidities.

INTRODUCTION: Impingement and penetration of the anterior cortex of the femur have been reported as complications after cephalomedullary nailing. The purpose of this study was to determine factors related to nail impingement in our population of Hispanic patients. MATERIALS AND METHODS: A non-matched case-control study was carried out and 156 patients who underwent cephalomedullary nailing from 2010 and 2013 were included; 78 cases with anterior cortical impingement and 78 control cases without impingement were documented. Demographic variables and specifications of the nails such as manufacture and radius of curvature were recorded. The presence of impingement, angle of incidence on radiographs--indirect measurement of the femoral bow on the sagittal plane--and nail entry site were determined. Bivariate and multivariate logistic regression analyses were performed to identify the factors associated with cortical impingement. RESULTS: The distribution by sex corresponded to 87 females (56%) and 69 males (44%) with a mean age of 75 years [SD 18.2]. Cortical impingement was presented in 78 cases (50%) and 6 (3.8%) patients evidenced penetration of the anterior cortex of the femur. On the bivariate analysis the posterior nail start site is highlighted, which showed a positive association with impingement (OR 4.3; 95% CI 1.1-36 and p = 0.04). After the multivariate analysis, the factors associated with anterior cortical impingement included female gender (OR 2.2; 95 % CI 1.1-4.6 and p ≤ 0.038), straight nails-short nails-(OR 4.9; 95% CI 2.2-10 and p ≤ 0.001) and angle of incidence ≥7° (OR 4.9; 95% CI 2.2-10 and p ≤ 0.001), the latter showing a likelihood of 57 % for impingement, increasing to 90% with an angle of incidence of 11°. CONCLUSIONS: Posterior entry site should be avoided and an anterior site should be used. Female gender, straight nails and greater angle of incidence of the femur were associated with cortical impingement. A specific intramedullary nail design is needed for the Hispanic population due to high impingement and anterior cortical penetration rates seen with conventional nails. Short curved nails and long nails with a lower radius of curvature are required.
