In order to assess the internal restraints and joint forces which had not been considered properly in initial design, a numerical approach was chosen.
The contribution of the capsular ligaments was not uniform: the ischiofemoral ligament provided primary internal rotation restraint in more than half the tested positions and was particularly prominent in high flexion (≥ 30°), adduction and internal rotation, or low flexion (≤ 30°), abduction and internal rotation (Fig. 5).
The internal rotation restraint and supporting sling protecting against subluxation in deep hip flexion (Figs 5 and 6) offered by the ischiofemoral ligament could benefit patients who have undergone THA by passively stabilising the hip in a position where few muscles have favourable lines of action.
In the absence of internal, moral restraints, external ones can only do so much.The world watched London in fascinated amazement.
Early-age cracking might be due to external loading, but also to the internal or external restraint resulting from autogenous, drying and thermal shrinkage.
With references to the relevant standards, sections address structural design of rigid, semi-rigid and flexible pipes, longitudinal stress, steel pipe wall thickness, resistance to internal forces, pipe restraint and thrust blocks.
The contraction of the material is normally hindered by either internal or external restraints so that tensile stresses are induced.
If nothing else, for a brief moment, a few days, we can embrace our full identity and worship freely without the internal or external restraints as a supposed walking dichotomy.
An internal risk assessment of restraint techniques, obtained by the Guardian, shows that certain procedures approved for use against non-compliant children carry a 40% or 60% chance of causing injuries involving the child's airway, breathing or circulation, the consequences of which could be "catastrophic".
The consensus of the ALL Expert Group is as follows: Mean load to failure: around 180 N, Mean stiffness: 31 N/mm, Function: the ALL acts as a restraint for internal rotation of the tibia and affects the pivot-shift in the ACL-deficient knee.
