ABSTRACT
PURPOSE: Several preoperation prognosis models used on the treatment of metastatic bone disease on appendicular skeleton have been devised. The purpose of this study was to compare the performance of different survival prognostic models on patients with metastatic bone disease in long bones in a Chilean population. METHODS: This is a multicentric retrospective study. We retrospectively reviewed the medical records of 136 patients who were confirmed with metastatic bone disease of the appendicular skeleton and who were treated surgically from 2016 to 2019. The minimum follow-up time was 12 months. All patients were assessed using four appendicular metastatic bone disease scoring systems. A preoperative predicted survival time for all 136 patients was retrospectively calculated making use of the revised Katagiri, PathFx, Optimodel and IOR score model. RESULTS: The PathFx model demonstrated an accuracy at predicting 3 (area under the curve [AUC] = 0.61) and 6-month (AUC = 0.65) survival time after surgical management. IOR score model demonstrated an accuracy at predicting 12-month survival time (AUC = 0.64). The survival rate reached the 44% in a year. The median survival time to death or last follow-up time was 14.9 months (SD ± 15). CONCLUSION: PathFx score model demonstrated the highest accuracy at predicting a survival time of 3 and 6 months. IOR score model was the most accurate measure at predicting a survival time of 12-months. To our knowledge, this is the first study reporting a comparative analysis of metastatic bone disease with predicting models in a country located in Latin America. PathFx's and IOR score models are the ones to be used in the Chilean population as the predictive models in metastatic bone disease of the appendicular skeleton.

La tuberculosis persiste siendo un problema importante a nivel mundial. A pesar de que el compromiso de la cadera es infrecuente, su aparición representa un escenario complejo. Presentamos un paciente masculino que desarrolló una infección de la cadera que fue diagnosticada como tuberculosis de forma tardía. El paciente recibió tratamiento médico por 6 meses y luego se realizó una artroplastia total de cadera en dos tiempos, con éxito. Presentamos el reporte de un caso completo, junto a su seguimiento al aão y una revisión de la literatura sobre el tema.
Tuberculosis remains a significant problem worldwide. Even thought hip involvement is an infrequent manifestation, itÌs appearance represents a challenging scenario. We present a male patient who developed a hip infection later discovered to be tuberculosis. The patient received a medical treatment protocol for 6 months and was subsequently treated with a two stage total hip arthroplasty. We present the full case report with itÌs 1-year outcome and a literature review.
