Here is a complete guide to giving an intramuscular (IM) injection in the hip/gluteal area.
Intramuscular (IM) Injection in the Hip
There are two main hip sites used for IM injections:
- Ventrogluteal site (preferred - gluteus medius/minimus)
- Dorsogluteal site (buttock - now discouraged)
Ventrogluteal Site (Recommended)
The ventrogluteal site is the current preferred site for IM injections in adults and children over 7 months. It has thick muscle, fewer nerves and blood vessels, and thinner overlying skin compared to the dorsogluteal (buttock) site.
Why it's preferred over the dorsogluteal site
- No major nerves or vessels nearby (the dorsogluteal site is close to the sciatic nerve and can cause leg paralysis if the nerve is hit)
- Thinner skin means the needle reliably reaches muscle
- Less painful
- Works for thin, average, and overweight patients
Step-by-Step: Finding the Ventrogluteal Site
Position the patient: Side-lying or standing, with the hip slightly flexed. The hip to be injected should be on top (if side-lying).
Landmarking - V Method (standard BMI)
- Use the opposite hand - if injecting the right hip, use your left hand
- Place your palm over the greater trochanter (the bony bump on the side of the hip)
- Point your index finger toward the anterior superior iliac spine (ASIS) - the bony point at the front of the hip
- Spread your middle finger back toward the iliac crest (top ridge of the pelvis)
- This creates a V shape - inject into the center of the V
Landmarking - G Method (geometric, works for all BMIs)
Draw imaginary lines from the bone landmarks (greater trochanter, ASIS, iliac crest) to form a triangle. Draw median lines from each corner. The injection point is where they intersect.
Performing the Injection
| Step | Action |
|---|---|
| 1 | Wash hands, gather equipment (syringe, needle, alcohol swab, gloves, medication) |
| 2 | Select correct needle length - typically 38 mm (1.5 inch) for most adults; longer for obese patients |
| 3 | Draw up medication, remove air bubbles |
| 4 | Clean the site with an alcohol swab and let it dry completely |
| 5 | Spread or bunch the skin depending on the patient (spread for most adults) |
| 6 | Insert the needle at a 90-degree angle in one smooth motion |
| 7 | Aspirate (pull back the plunger slightly) - check for blood; if blood appears, withdraw and restart |
| 8 | Inject the medication slowly (about 1 mL per 10 seconds) |
| 9 | Withdraw the needle smoothly at the same angle |
| 10 | Apply gentle pressure with a cotton ball or gauze - do not rub (rubbing can cause irritation or force medication into subcutaneous tissue) |
| 11 | Dispose of needle safely in a sharps container - never recap |
Needle Size Guidelines
| Patient | Needle Gauge | Needle Length |
|---|---|---|
| Average adult | 21-23 G | 38 mm (1.5 in) |
| Thin adult | 23-25 G | 25 mm (1 in) |
| Obese adult | 21-23 G | 50-75 mm (2-3 in) |
Z-Track Technique (for irritating medications)
For medications that stain or irritate tissue (e.g., iron injections):
- Pull the skin and subcutaneous tissue 2-3 cm to the side before inserting the needle
- Insert and inject normally
- Wait 10 seconds after injecting
- Withdraw the needle, then release the skin - this seals the track and prevents leakage upward
Key Safety Points
- Never inject into the dorsogluteal (upper outer buttock) unless specifically directed - risk of sciatic nerve injury
- Always aspirate before injecting (especially for the gluteal area)
- Rotate sites if giving frequent injections
- Maximum volume per ventrogluteal site: 3-5 mL for an adult
- The ventrogluteal site should not be used in children under 7 months
This video tutorial by Nurse Sarah gives a clear visual demonstration of the ventrogluteal IM technique:
Note: This is a clinical skill. If you are a patient giving injections at home (e.g., for self-administered medications), your healthcare provider should train you in person before you attempt this independently.

Medical anatomical diagram of the hip bones showing the ventrogluteal injection site landmarks. Clear illustration of the pelvis and upper femur from the lateral/side view, highlighting the iliac crest, anterior superior iliac spine (ASIS), and greater trochanter of the femur. Show the V-shaped hand landmarking technique with index finger pointing to the ASIS and middle finger spread toward the iliac crest, forming a V shape. Label the bones clearly: iliac crest, anterior superior iliac spine, greater trochanter, and mark the injection point at the center of the V. Medical textbook style, clean white background, labeled diagram.
Here are the three key bones/landmarks that form the V shape for the ventrogluteal injection:
- Iliac Crest - the top ridge of the pelvis (your middle finger follows this)
- Anterior Superior Iliac Spine (ASIS) - the bony point at the front of the hip (your index finger points here)
- Greater Trochanter of the Femur - the large bony bump on the outer side of the upper thigh (your palm rests on this)
The injection point sits in the center of the V formed between your index and middle fingers - this is the safe zone over the gluteus medius muscle, well away from the sciatic nerve.
