False.

It is not true that a rheumatologist specializes in diagnosing and treating diseases and disorders involving the bones, joints, and muscles.

Explanation:

A rheumatologist is a doctor who examines the internal medicine of patients in case of treating inflammatory conditions.The rheumatologist treats and diagnoses the patients with problems related to different aspect that affects the joints, tendons, ligaments, bones, and muscles.It is a basic fact that rheumatologist do not perform any surgery instead they treat musculoskeletal conditions.So they do not treat any disorders of bones or joints but they diagnose the inflammatory conditions affecting the bones and joints.
