Musculoskeletal ultrasound shows tendons, muscles and joints in real time. Learn when it is used for shoulder pain, tendon tears, heel pain and guided injections.
Musculoskeletal ultrasound shows tendons, muscles, ligaments, bursae and joint fluid in real time, and lets the doctor press on the painful spot and move the joint during the scan. It is widely used for shoulder pain (rotator cuff and bursitis), tennis elbow, heel pain, tendon tears and to guide injections. It is quick, radiation-free and less costly than MRI, but MRI is better for deep joint structures.
Why Choose Ultrasound for Soft Tissue?
Ultrasound is dynamic: the sonologist can see the tendon glide during movement and compare with the other side. It is excellent for superficial structures and tendons, allows immediate answers and can guide an injection precisely. It cannot see inside bone or deep joint structures such as the labrum, so MRI is added if needed. See MRI shoulder scan.

- Shoulder pain with limited lifting or night pain
- Tennis and golfer's elbow. See MRI elbow scan
- Heel and sole pain; Achilles problems
- Wrist swelling, ganglion cysts and carpal tunnel causes
- Muscle strain, lumps and swellings
- Hip and knee fluid collections
Ultrasound-Guided Injections
Under ultrasound view, a doctor can place a steroid or other injection exactly into a bursa, tendon sheath or joint, which is more accurate and safer than a blind injection. Repeated steroid injections in the same tendon should be avoided because they can weaken it. Platelet-rich plasma and other options are used in selected cases.
Preparation and Procedure
No fasting or special preparation is needed. Wear loose clothes that expose the area. The scan takes 15 to 20 minutes. The sonologist may ask you to move the shoulder or foot during scanning. Bring previous X-rays or MRI reports. See ultrasound abdomen for another common ultrasound use.
Limits
Ultrasound results depend on the skill of the operator. It cannot assess bone marrow, deep cartilage, the labrum and structures hidden by bone. A normal ultrasound does not rule out all causes of pain, such as neck problems that refer pain to the shoulder.
A Practical Example
Meera, 52, has shoulder pain when lifting her arm and at night. Ultrasound shows a partial tear of the supraspinatus tendon and fluid in the bursa. Her doctor advises physiotherapy and an ultrasound-guided injection into the bursa, and her pain improves in weeks. A friend with an unclear shoulder problem goes on to MRI.
Key Facts at a Glance
- Ultrasound shows tendons and bursae in real time
- No radiation and no preparation needed
- It guides injections accurately
- MRI is better for deep joint structures
After the Scan and Next Steps
Take the report to an orthopaedic or sports medicine doctor. Rest from the aggravating activity, learn physiotherapy exercises, correct posture and gradually return to activity. Avoid repeated steroid injections in the same tendon. Report sudden loss of strength, a visible gap or deformity, or fever with a swollen joint promptly.
Questions to Ask Your Doctor
- Is my pain from the tendon, the bursa or the joint?
- Is my tear partial or complete?
- Do I need MRI, an injection or surgery?
- When can I return to sport or work?
Common Mistakes to Avoid
- Repeated steroid injections without rehabilitation.
- Ignoring night pain and weakness.
- Returning to heavy lifting too early.
Booking, Timing and Report
Ultrasound is usually available without a long wait, and many scans can be done the same day. Carry your doctor's prescription and old ultrasound reports, and follow the instructions about a full or empty bladder or fasting. The scan takes 15 to 30 minutes, and the report is usually ready the same day.
