ABSTRACT
INTRODUCTION: A metastasis is the tumor cell capacity to migrate from the primary tumor and implant itself in tissues of an organ at a distance by hematogenous, lymphatic or contiguity. The main causes of bone metastases are: breast, prostate and lung cancer. It usually occurs in patients over 50 years of age. There is a predilection for metastasizing to the axial skeleton. OBJECTIVE: To determine the frequency of tumors that produce bone metastases in our institution. MATERIAL AND METHODS: Observational, cross-sectional, descriptive study, for retrospective analysis of the cases of patients diagnosed with bone metastases. RESULTS: 193 cases; 121 women and 72 men with an age range of 42 to 84 years. Cancers associated with bone metastases were breast, lung, prostate, cervical and renal cancers; to a lesser extent other such as colon, thyroid, liver and skin. The most affected bones were axial skeleton: lumbar and dorsal spine, and in appendicular skeleton the femur in the diaphysiary region and in the humerus the proximal third. At present it has not been possible to improve the effectiveness of timely detection strategies, so bone pain should begin with a protocol of tumor suspicion. CONCLUSIONS: More than 80% of the patients came for fracture. All patients had a history of pain greater than 12 months with no prior study protocol.
INTRODUCCIÓN: Una metástasis es la capacidad celular tumoral para migrar del tumor primario e implantarse en tejidos de un órgano a distancia por vía hematógena, linfática o contigüidad. Las principales causas de metástasis óseas son: cáncer de mama, próstata y pulmón. Habitualmente se da en pacientes mayores de 50 años. Existe predilección por metastatizar al esqueleto axial. OBJETIVO: Determinar la frecuencia de los tumores que producen metástasis óseas en nuestra institución. MATERIAL Y MÉTODOS: Estudio observacional, transversal, descriptivo, para análisis retrospectivo de los casos con diagnóstico de metástasis ósea. RESULTADOS: Ciento noventa y tres casos; 121 mujeres y 72 hombres con rango de edad de 42 a 84 años. Los cánceres asociados a metástasis ósea fueron cáncer de mama, pulmón, próstata, cervicouterino y renal; en menor proporción otros como colon, tiroides, hígado y piel. Los huesos más afectados fueron esqueleto axial: columna lumbar y dorsal; en esqueleto apendicular el fémur en la región diafisaria y en el húmero el tercio proximal. En la actualidad, no se ha logrado mejorar la efectividad de estrategias de detección oportuna, por lo que los cuadros de dolor óseo deben iniciar con un protocolo de sospecha tumoral. CONCLUSIONES: Más de 80% de los pacientes acudieron por fractura. Todos tenían historial de dolor mayor a 12 meses sin protocolo de estudio previo.

ABSTRACT
Objetivo: Reportar la capacidad de la proteína morfogenética de lograr la consolidación ósea en pacientes con seudoartrosis congénita de tibia. Pacientes y métodos: Se realizó en tres pacientes con diagnóstico de seudoartrosis congénita de tibia, se hizo seguimiento durante seis meses a cada uno observando la consolidación y capacidad funcional de la extremidad. Resultados: Se logró consolidación en todos los casos presentándose ésta a los tres meses y medio en promedio. Conclusiones: La proteína morfogenética tiene utilidad como coadyuvante para conseguir la regeneración y consolidación ósea en pacientes con seudoartrosis congénita de tibia.
Objective: To report the ability of bone morphogenetic protein to achieve bone healing in patients with congenital pseudoarthrosis of the tibia. Patients and methods: Three patients with a diagnosis of congenital pseudoarthrosis of the tibia were followed-up for six months. Bone healing and functional capacity of the limb were observed. Results: Bone healing occurred in all cases at a mean of three and half months of treatment. Conclusions: Morphogenetic protein is useful as an adjuvant to achieve bone regeneration and healing in patients with congenital pseudoarthrosis of the tibia.

The developmental dysplasia of the hip (DDH), where the spectrum of deformity varies from a slight mismatch in the articular surfaces between the ilium and femur, which will bring a premature wear of the joint, until the situation more serious when the femoral head is out of the acetabulum, causing a host of disorders side as curvature of the spine, significant shortening of the limb deformities in the knee and the contralateral hip, as well as causing pain and loss of joint mobility mentioned. All this makes the spectrum of abnormalities in a person being disabled with a social and economic burden for the family and society. "Preventing" a clinical entity such as developmental dysplasia of the hip does not mean to anticipate the presentation, because children continue to be born with this problem, but to have a program for early detection and early treatment and thus prevent the occurrence. The goal of this study was to provide the medical community that timely tool for prevention. When diagnosed and treated in a timely and favorable prognosis qualified for motor function and quality of life.

Osteoblastic osteosarcoma is the most frequent malignant bone neoplasia in pediatric patients. It accounts for 50% of primary bone tumors and the most frequent age at presentation is adolescence, particularly during the growth spurts. Cases of children younger than 8 years of age have been reported in the literature. The purpose of this article is to report the case of a male, 19 month-old patient with osteoblastic osteosarcoma of the left distal femur and proximal tibia. It is considered as a special case due both to the age at presentation and to the multicenter feature of the tumor. This suggests that this entity may be more aggressive and rapidly growing in younger children. At the National Pediatrics Institute, in 35 years we only had three cases of children younger than 5 years.
