hallo dear friend ,thanks for writing to HCM
i hv studied your case
in old age these kind of picture is due to degeneration process
yes
joint replacement surgery will give you relief to your hip pain
it will give you better mobility
but will not answer to your spine pain
spine pain will go on increasing day by day
so for better mobility you have to solve both problem
epidural injection in spine can control your spine problem
you need some neurotropics like
pregabalin and calcium suppliment with vit D
avoid lifting weights
sit with taking support to your back
continue spine strenghthening exersizes
you may need
MRI SPINE
hope this information will help you
