Answer :
Final answer:
The surgery involving the implantation of metal rods is for treating scoliosis. Option (B) is correct.
Explanation:
Scoliosis is the condition treated with the described surgery involving the implantation of bilateral metal rods with pedicle screws or other implants through an anterior or a posterior approach and fusion with bone grafting.
This procedure aims to enhance the stability of the spine by allowing some movement, similar to the natural functioning of vertebrae, rather than complete fusion.
The surgery is not typically performed for spinal stenosis, herniated disc, or degenerative disc disease as they have different treatment approaches.
