In this context, the question is about whether cervical facet injections provide lasting pain relief in whiplash-associated disorder. The finding from Souza is that these injections did not lead to greater pain reduction at three months. So, the statement that they were NOT associated with a bigger improvement at three months is correct. The idea is that any early or short-term relief from the injection did not persist or translate into a superior outcome at the three-month mark, according to that study.

Understanding this helps you see why the result isn’t indicating a meaningful long-term benefit. In whiplash, pain can be influenced by many factors beyond the localized facet joints, and recovery trajectories vary, which can dilute longer-term effects of a single intervention. While facet injections might offer some short-term or diagnostic value in certain patients, Souza’s data suggest no added advantage in pain reduction by three months for this condition.

If you’ve seen options suggesting a clear benefit, no data, or unclear results, those would not align with Souza’s reported finding.
