Hi Ryan. If it has been 2 years and if ur not having low back pain
, it is likely that there is fusion between L5 and S1 which is the main aim of inserting screws and placing a cage. An x ray
of your lumbosacral spine will confirm the fusion. If there is still doubt in xray ..then a CT scan
will surely confirm the fusion. Once you confirm that it has fused, then there is no need to worry...U can bend, lift weight and lead a normal life.
