Previously, we showed that case-specific non-linear
finite element (FE) models are better at predicting the load to failure
of metastatic femora than experienced clinicians. In this study
we improved our FE modelling and increased the number of femora
and characteristics of the lesions. We retested the robustness of
the FE predictions and assessed why clinicians have difficulty in
estimating the load to failure of metastatic femora. A total of
20 femora with and without artificial metastases were mechanically
loaded until failure. These experiments were simulated using case-specific
FE models. Six clinicians ranked the femora on load to failure and
reported their ranking strategies. The experimental load to failure
for intact and metastatic femora was well predicted by the FE models (R. 2. =
0.90 and R. 2. = 0.93, respectively). Ranking metastatic
femora on load to failure was well performed by the FE models (τ =
0.87), but not by the clinicians (0.11 <
τ <
0.42). Both the
FE models and the clinicians allowed for the characteristics of
the lesions, but only the FE models incorporated the initial bone
strength, which is essential for accurately predicting the risk

The femoral head receives blood supply mainly
from the deep branch of the medial femoral circumflex artery (MFCA).
In previous studies we have performed anatomical dissections of
16 specimens and subsequently visualised the arteries supplying
the femoral head in
55 healthy individuals. In this further radiological study we compared
the arterial supply of the femoral head in 35 patients (34 men and
one woman, mean age 37.1 years (16 to 64)) with a
