I can help with interpretation but a diagnosis requires much more that x-ray results. Loss of lordosis could be from degenerative disc changes or simply positioning when the x-ray was taken. It may not mean much.
Spondylosis simply means degeneration of discs or facets. It may or may not mean much. Disc spaces significantly narrowed means degenerative disc disease and would fit with loss of lordosis from degenerative discs.
Calcificantion of the posterior longitudinal ligament at C5 may mean an old injury, ossification of the PLL (a disorder more commonly seen in Asians) or a calcified disc herniation.
Again- x-rays are used in conjunction with a history, physical examination and other tests (MRI etc.) to come up with a diagnosis.
