Question

i dont know yet

Explanation:

Arthrocentesis is a fluid - removal procedure from a joint, not for bone diagnosis. Arthroscopy is for joint visualization, not ideal for the given bone conditions. MRI is good for soft - tissue and some bone details but not the most specific for the wide range of bone issues mentioned. A bone scan is highly sensitive in detecting metastatic bone cancer, fractures, early infections, and certain degenerative bone diseases by detecting areas of increased bone metabolism.

Answer:

Bone scan
