The possible direction of applying the ERC, and the gap between the PRECICE nail and the ERC resulting from soft tissue in the thigh particularly in obese patients may make magnet-induced rotations difficult.
However, the lens can make the measurement of the in-plane rotation very difficult and impractical.
Axial vertebral rotation is difficult to assess on 2D radiographs but it may be explored with CT scans and 3D CT reconstructions [24, 25].
Interpretation of the signed translations and the rotations is difficult, as values may cancel each other with means/medians close to 0. Since our interest was only in the amount and progression of migration, we only assessed the absolute values statistically.
Shorter rotations allowed those in a difficult rotation to adopt a 'wait it out' attitude and look forward to the end.
The return of Shumpert, Harrellson and Baron Davis, combined with the recent signing of J.R. Smith, creates a crowded rotation and some difficult decisions for Coach Mike D'Antoni.
Assembly with rotation is a difficult problem and remains unsolved.
It is observed from the literature review that the rotation operation is difficult to handle in image hashing techniques [21].
For many EM clerkships, a final exam is taken at the end of the rotation, making it difficult to have time to remediate a potential knowledge deficit until the rotation is complete.
It required the voluntary participation of busy medical students on a difficult rotation.
