[|Human|] Hi, What does "Increased osteoblastic activity in the left acromioclavicular joint, lower cervical T9, T11-T12 and L4-L5 vertebrae is more likely degenerative in nature" means? The patient was diagnosed with prostate cancer three months ago and had undergone TURP.
[|AI|]  Hi I am Chat Doctor. .  In my opinion it means increased the activity of bone forming cells called osteoblasts and that's is the opposite of degenerative where bone resorption cells called osteoclasts transform bone to calcium.  Both formation and degeneration cause joint pain and arthritis so I think your acromioclavicular joint mobility is reduced and causes pain when overstretching your muscle origins while your vertebrae may show mild cervical disc herniation so I think you may visit your neurologist for proper evaluation and management.
