Propósito: validar el "Michigan Hand Outcomes Questionnaire" para el uso en población clínica colombiana, obtener una versión en español que tenga equivalencia trans-lingüística y evaluar la fiabilidad, sensibilidad al cambio, validez de contenido y de constructo del instrumento traducido y adaptado al español. Métodos: estudio observacional de validación de una escala en 205 pacientes colombianos con patología de mano asistentes a las consultas de cirugía plástica, rehabilitación y reumatología en un Hospital Universitario de referencia regional. Resultados: el análisis de componentes principales mostró seis dominios. A pesar de tener el mismo número de dominios, el contenido de algunos de ellos fue diferente a las subescalas originales. Se evaluó la consistencia interna incluyendo los 37 ítems de la escala original y se obtuvo un valor de Alfa de Cronbach de 0,92. Todas las subescalas tenían buena reproducibilidad prueba-reprueba excepto dolor. Al evaluar los resultados de la escala, tres y seis meses después de su primera aplicación, se pudo observar que había diferencias estadísticamente significativas en la puntuación total y en la de cada una de las subescalas. Conclusiones: la versión en español para Colombia del Michigan Hand Outcomes Questionnaire tiene buena confiabilidad, validez y sensibilidad al cambio. La evaluación de consistencia interna indicó que la escala podría ser acortada y posiblemente mejoren aún más sus propiedades psicométricas.
Purpose: to validate the Michigan Hand Outcomes Questionnaire for its use in Colombian clinical population: to translate and adapt the scale in order to obtain a cross-linguistically equivalent version in Spanish, and to assess the reliability, sensitivity to change, and content and construct validity of the Colombian Spanish version. Methods: observational study to validate a scale in 205 Colombian patients of plastic surgery, rehabilitation, and rheumatology in a University Hospital, who had a hand disorder. Results: the principal component analysis showed six domains, as in the original questionnaire, but the content of some of them differed from the original MHQ scales. We assessed internal consistency of the entire 37-item original scale, and Cronbachs alpha was of 0,92. All scales had good test-retest reproducibility, except for the Pain scale. Upon evaluation of the results of the scale three and six months after its first application, significant differences could be observed in the total score as well as in the scores for each of the scales. Conclusions: the Colombian Spanish version of Michigan Hand Outcomes Questionnaire has good reliability, validity, and sensitivity to change. Assessment of internal consistency indicated that the scale could be reduced and its psychometric properties would possibly improve.

BACKGROUND: One goal of lipoplasty is to create a round and projected buttock contour. Despite multiple papers evaluating lipoinjection, controversies still remain. METHODS: This report describes a series of patients who underwent liposuction, gluteal lipoinjection, and evaluation with magnetic resonance imaging (MRI). From January 2003 to January 2004, the patients scheduled for contour surgery by the investigators were evaluated using MRI, photographic records, and gluteal circumference measurement 1 week before surgery, then 2 weeks and 3 months after the procedure. A statistical analysis was performed for 10 patients who received, on the average, a 350-ml injection of fat obtained during liposuction. RESULTS: Gluteus muscle volume increased, reaching a higher level 2 weeks after the injection than the level 3 months afterward (p < 0.001). The gluteal circumference, modified 2 weeks after surgery by about 1 to 3 cm, came back to previous values 3 months after the procedure (p < 0.05), a phenomena interpreted as reabsorption and resolution of the postoperative edema. There is no correlation between the gluteus muscle volume obtained by MRI and the gluteal circumference (p > 0.05). CONCLUSIONS: The findings led to the conclusion that enhancement of the gluteal contour after fat injection results from survival of the injected tissue 3 months after the surgery, which was objectively evaluated by MRI as having a calculated reabsorption rate of 24% to 36%.
