What does " there is some minimal cystic change in the lunate" mean as stated by an mri. how serious is it and what can be done ? from weightlifting.

Mild arthritis: Cystic changes can be incidental, or the beginning of the develpoment of a ganglion cyst. Unless there is severe pain, this is usually nothing to be worried about.

Repeated trauma: We believe that mechanical stress and repeated minor trauma near the surface of the bone may lead to intramedullary vascular disturbance with consequent foci of aseptic bone necrosis. The revitalisation of these areas causes fibroblastic proliferation, followed by mucoid degeneration of the connective tissue into cysts.. Curettage or excision is usually effective, and recurrence is rare.

Prob not important: Small bone cysts in the lunate are common. Unless the cortex of the bone is involved, these are usually not related to pain. Not having seen the mri, it is not clear that this is of any importance at all. You might ask your doctor the same question though, as the MRI may have contained more detail.
