ABSTRACT Objective: To assess the adequacy to the Brazilian population of orthopedic implants used for treatment of proximal femoral fractures. Methods: The neck-shaft angle of the femur of 101 patients was measured in anteroposterior pelvis radiographs and these measurements were correlated to gender, age, height, weight and ethnicity. In addition, we compared the values of the neck -shaft angle with the angulation of the main implants available in the Brazilian market for the treatment of transtrochanteric fractures. Results: Of the 101 measurements, an average of 130.9±6.7° was obtained, ranging from 112° to 150°. Correlating these measurements with epidemiological variables, only age was statistically significant. Conclusion: Most of the analyzed population presented anatomical characteristics that allow the proper use of these implants to treat transtrochanteric fractures, as indicated from the analysis of neck-shaft angles. Nonetheless, 4% of individuals did not fit this pattern and would have required alternative implants. Level of Evidence III, Study of nonconsecutive patients; without consistently applied reference ''gold'' standard.

OBJETIVO: avaliar a capacidade funcional da articulação do quadril e a qualidade de vida de pacientes portadores de osteoartrose submetidos à artroplastia total. MÉTODOS: foram avaliados 12 pacientes através do questionário Harris Hip Score (modificado/ escala de 0-95 pontos) e goniometria no pré e pós-operatório de artroplastia total de quadril. RESULTADOS: a amplitude de movimento mostrou-se incompleta em todos os arcos de movimento no pré-operatório. No pós-operatório os valores aumentaram significativamente na flexão (p=0,007), extensão (p=0,02), abdução (p=0,001), rotação medial (p=0,0002) e lateral (p=0,01), apenas o aumento do movimento de adução de quadril não foi significativo (p=0,08). A medida do escore obtido através do questionário no pré-operatório foi 39,7 pontos e no pós-operatório 74,1 pontos (P<0,000001). CONCLUSÕES: a artroplastia total do quadril proporciona ao paciente alívio da dor, melhora na realização das atividades da vida diária e aumento da amplitude do movimento articular do quadril. Os pacientes, porém, relatam medo e insegurança na realização dessas atividades.

OBJECTIVE: To evaluate the functional capacity of the hip articulation and the quality of life of patients with osteoarthritis submitted to total artroplasty. METHODS: 12 patients were assessed through the questionnaire Harris Hip Score (modified/scale of 0-95 points) and goniometry in the pre- and post-surgery of total hip artroplasty. RESULTS: The pre-surgery questionnaire score was 39.7 and in the post-surgery the average score reached 74.1 points (p = 0.000001). The range of motion of the hip was incomplete in all the movement arches in the pre-surgery, but in the post-surgery this value increased significantly in flexion (p = 0.007), extension (p = 0.02), abduction (p = 0.001, medial rotation (p = 0.0002) and lateral rotation (p = 0.01); only the aduction movement was not significantly increased (p = 0.08). CONCLUSIONS: Total hip artroplasty reliefs patients pain, improves daily life activities and increases the hip range of motion; patients, however, relate fear and insecurity in the accomplishment of those activities.
