Lumbar facet joint effusion in MRI: a sign of instability in degenerative spondylolisthesis?
Facet joint effusion is clearly correlated with spontaneous reduction of the extent of slippage in the supine position compared to the upright position. Also, the greater the difference in right and left facet effusion, the higher the likelihood of having a RT. Future studies should assess whether analysis of facet joint effusion measured on routine MRI can help in decision-making regarding the optimal surgical treatment to be applied (decompression alone or combined with fusion).
The RD is unlikely to have contributed significantly to reducing alcohol consumption, as most alcohol pledge signatories appear to have committed to actions that they would have undertaken anyway, regardless of the RD. Irrespective of this, there is considerable scope to improve the clarity of progress reports and reduce the variability of metrics provided by RD pledge signatories.
