Unicortical screws or insufficient graft compression can result in nonunion and breakage of screws [5, 33].
Post-operative radiographs in these two models also showed an osteotomy gap, suggesting insufficient inter-fragmentary compression.
In advanced stages of calcification of the arterial wall cuff pressure is insufficient to achieve compression of the arterial vascular tree.
The outcome of cardiopulmonary arrest, as measured by survival rate and cerebral performance category (CPC), is worse when the quality of CPR is suboptimal in some way, such as insufficient depth of chest compression or an excessive number of ventilations.
There was insufficient evidence to determine whether higher compression forces in larger breasts were due to increased glandular content.
A post-compression exposure of tablets to the vapors of appropriate solvents realizes the necessary compaction of matrices, in fact, a high compression force (3 ton) is insufficient, per se, to prevent matrix disintegration in the dissolution medium, whereas such a disintegration is prevented by the treatment with solvent vapors, even with a low compression force (0.3 ton).
However, the efficacy of manual jugular vein compression may be limited to insufficient pressure and may even cause serious side effects such as a decrease in cerebral blood flow by direct carotid artery compression.
These vascular conduits may suffer not only from insufficient tensile strength, but also from vulnerabilities related to compression, torsion, and pulsatile pressurization.
There was found insufficient prevalence and incidence rate to conclude for radial nerve compression and pronator teres syndrome [see Additional file 3].
In CSA, lesions to the anterior horn cells are a result of an indirect insufficient blood supply due to cervical canal stenosis, or by compression or stretching of the intra- and extramedullary vessels with movements of the cervical spine [ 3].
