Final answer:
There is no correct answer listed in the options provided, as rotator cuff tear, osteoarthritis, rheumatoid arthritis, and bicipital tendinitis are all intrinsic to the shoulder or its immediate structures, whereas an extrinsic disorder would come from outside the shoulder joint.
Step-by-step explanation:
The question pertains to identifying an extrinsic disorder that could lead to frozen shoulder, also known as adhesive capsulitis. Frozen shoulder involves the formation of scar tissue leading to reduced shoulder mobility due to the inflammatory response after an injury or disorder. Among the provided options, osteoarthritis and rheumatoid arthritis are intrinsic joint diseases that may contribute to frozen shoulder through inflammatory processes within the joint itself.
However, rotator cuff tear and bicipital tendinitis are disorders related to the tendons surrounding the shoulder, not extrinsic disorders. Therefore, none of the listed options are technically considered 'extrinsic disorders' in the context of leading to a frozen shoulder, as they are all intrinsic to the shoulder joint or its immediate structures.
