Msk Guided Injection 1 Ultrasound Scan

• What it does: Combines high-resolution imaging with a single, accurate medication injection
• Duration: Complete visit—including scan, injection, and recovery—takes ≤30 minutes
• Goal: Pinpoint the exact source of pain and deliver medicine where it’s needed most

Real-time ultrasound guidance explained

A small probe glides over your skin, sending painless sound waves into the joint or tendon. The live picture appears on a monitor, letting the physician watch the needle travel to the precise trouble spot.

Diagnostic vs therapeutic injection

• Diagnostic: A tiny amount of anesthetic confirms the pain source.
• Therapeutic: Steroids, hyaluronic acid, PRP, or Botox are injected for long-term relief.

• Corticosteroid – fast anti-inflammatory
• Hyaluronic acid – joint lubrication for osteoarthritis
• Platelet-rich plasma (PRP) – healing boost for tendons
• Botulinum toxin (Botox) – muscle spasticity relief

• Joint effusion volume (excess fluid)
• Tendon integrity & sheath thickness
• Needle placement accuracy in real time

• Confirm the exact pain generator
• Deliver medication directly, avoiding pill side-effects
• Reduce or eliminate the need for surgery

Look for these signs:

• Joint pain lasting >6 weeks
• Tendonitis or bursitis flare-ups
• Sports injuries (tennis elbow, runner’s knee)
• Chronic inflammatory conditions like rheumatoid arthritis

• Higher accuracy: up to 96 % vs 60 % for blind injections
• Radiation-free: safe for repeated use
• Faster recovery: shorter procedure, less tissue trauma

• Rotator-cuff tendinopathy
• Plantar fasciitis
• Carpal tunnel syndrome
• Frozen shoulder
• Golfer’s or tennis elbow

• Bring: List of current medications and any recent imaging reports
• Do NOT fast—eat and drink normally
• Wear: Loose clothing that exposes the target joint or limb

• Disclose blood-thinning meds (aspirin, warfarin)
• Notify staff of allergies to local anesthetics or latex
• Arrange a short ride if you feel anxious about needles

• When: Any time of day; avoid during active skin infection
• Who: Adults and teens ≥15 kg; pregnancy cases handled individually

1. Consent – explanation and signature
2. Skin prep – sterile wipe and mark
3. Ultrasound scan – locate problem area
4. Needle insertion – watch live on screen
5. Injection – medication delivered
6. Monitoring – 10 minutes observation before discharge

Tell the team if you are: pregnant, breastfeeding, allergic to lidocaine, or on strong blood thinners.

• Common but mild: tiny bruise, brief swelling
• Rare: infection (1 in 10,000)
• Limitations: very deep joints or high BMI may need MRI guidance instead
