As a quad I have used my thumb over the decades in various ways to lift and push on things that have probably resulted in unnatural forces in biomechanically disadvantageous directions. The result is now excruciating pain doing the most trivial of activities and even at rest. MRI and x-ray shows nothing overtly obvious. It may just be a situation of ligamentous laxity, chronic hyperextension, as well as joint and neuronal compression.
All minor treatment options have proven ineffective. There is really nothing left to do except to consider a thumb fusion. However even the hand surgeon I go to is loath to do it, citing his one experience with the quad where the healing process took repeated surgeries over the period of a year for the fusion to take. At least that's what he says.
If this is the route chosen, I can only imagine the nightmare of the healing process in which all weight-bearing will probably need to be eliminated for at least 2 to 3 months. This would make all ADLs impossible and necessitating getting a Foley for that period, which I've had before for such issues and which is the least of my long-term worries.
Any knowledge of such maladies or people that have had similar problems?
