Introduction: Studying the detailed anatomical features of the femoral medullary area (MA) is fundamental before intra-medullary nailing and knee or hip arthroplasty. We hypothesized a method to measure the regular MA and to correlate it with the actual femoral MA. Material and methods: Serial cross-sectional were taken perpendicular to the longitudinal axis of the bones at regular distances of 50 adult (20-55 years) femoral CTs and 50 adult dry femora (25 male femora and 25 female femora). After identifying the anatomical directions, the actual MA was measured after delineation; the regular MA was measured by filling the medullary cavity with an ellipse where it touches the cavity all through its identifiable margins. The perpendicular diameters were identified and measured. Results: The narrowest actual and regular MA in both males and females either in bones or in CT were at the level of 70%. There was a significant increase in both regular and actual MA in bones than in CTs in most of the studied levels in males and females. A positive correlation between femur length and both regular and actual MA in bones and CT in most of the studied levels in males and females was found. We estimated an equation to predict the regular from the actual MA at all studied levels. Conclusion: Our results may add to the prospective studies that might help improving designs of the femoral implants. [ABSTRACT FROM AUTHOR] |
