Objective: Evaluate the influence in the position of the anti-rotational device in cephalomedullary nails and its influences on the consolidation of trochanteric fractures. Methods:Retrospective case series comprising 58 patients with unstable trochanteric fractures that underwent osteosynthesis with cephalomedullary nail and anti-rotational device. Were analyzed the radiographs of the pelvis and ipsilateral hip osteosynthesis with 6 months postoperatively and compared to initial. The radiographic parameters used were tip-apex index (TAD), the positioning of the sliding screw in relation to the central axis of the femoral neck, the angle of reduction and fracture healing.Results: From the 58 patients selected for initial postoperative examination, 15 (26%) died, 6 (10%) lost the thread of the treatment and 37 (64%) were reassessed. Most of them were female patients, beteween the ninth and tenth decade of life. It was observed that 31 (84%) fractures were consolidated, while 6 (16%) patients had their fractures not yet consolidated. The reduction angle in healed fractures was 129o and in non-healed were 136o. In these, the position of the sliding screw was far from the central axis of femoral neck. Conclusion:The fixation of trochanteric fractures with cephalomedullary nail with anti-rotational device is safe. The reduced fractures with valgus above 135 ° showed higher rates of nonunion. In these cases the position of the sliding screw was lower than ideal to fit the anti-rotational device, which may have affected negatively the fracture healing.

Objective: The objective of this study is to present demographic data on the occurrence of spinal metastases in the service where the work was performed and to investigate the reliability of the modified Tokuhashi score in the decision making in patients with metastatic spinal cancer. Methods: We conducted a review of medical records of all cases of vertebral bone metastasis, confirmed by anatomopathological examination, from January 2009 to June 2012. Data review included demographic details, origin of the primary cancer, duration of symptoms, localization of metastases, Karnofsky performance scale and survival based on modified Tokuhashi score. We divided patients into three groups. Group A included patients with life expectancy of less than six months, group B included patients with life expectancy of between six and 12 months, and group C included patients with a life expectancy of more than 12 months. We compared the calculated survival with the current survival in the three groups with all patients followed-up to a minimum of 1 year or until death. Results: The predict survival in group A was 63.6% according to the modified Tokuhashi score, albeit group B had only 30% agreement. Conclusions: For patients in group A, the agreement rate of patient survival was better (63.4%) than that observed in patients in group B (30%). Our sample had no patient classified as group C.Keywords: Spine; Neoplasm metastasis; Bone and bones; Survival analysis; Demographic data. RESUMO Objetivo: O objetivo do trabalho é apresentar dados demográficos sobre a ocorrência de metástases na coluna vertebral no
