Hip Ozone Injection Protocol
Lateral approach, landmarks, needle and schedule for ozone hip injections, with the Prolozone mixture and ozone-oxygen approaches side by side.
Quick answer: Ozone hip injection uses a lateral approach with a 25G × 2 in needle (Wright). Madrid lists 10–20 mL at 10–20 µg/mL, weekly. The sheet compares the Prolozone mixture and ozone-oxygen approaches.
Warning
Requires hands-on training from an experienced physician
Hip ozone injection should only be performed by a practitioner trained in it by an experienced physician.
Practitioner-only procedure. Injecting ozone, with or without a nutrient mixture, is done by trained, licensed clinicians. This sheet is a reference for them. It is not a self-treatment guide and not medical advice. Strict sterile technique is required every time.
What are the basics of ozone hip injection?
- Madrid lists osteoarthritis, necrosis, synovitis and acetabular impingement as indications for coxofemoral infiltration, with the aims of delaying surgery, reducing pain and restoring mobility.
- Prolozone, as Dr. Jeff Wright teaches it, adds nutrients and ozone to damaged tissue. His explanation: swollen tissue receives less blood, which leaves the area short of oxygen, and ozone supplies bioavailable oxygen.
- Wright's expected course from his own practice: a second injection 10 to 14 days after the first, with results after as few as 3 injections or as many as 6 to 8. Chronically ill patients can need more. He describes his success as 90 to 95 percent. That is his clinical impression, not a trial result.
- Wright's tutorials do not state ingredient amounts. The solution he used is a compounded pre-mix of methylcobalamin (vitamin B12), pyridoxine (vitamin B6), dextrose and procaine. The amounts are in the table below, taken from the compounded formula sheet. He also describes drawing up individual nutrients in a hood.
- The Madrid Declaration describes ozone-oxygen infiltration only: no nutrient mixture. Both are shown side by side below and labeled.

What dose and technique are used for ozone hip injection?
Two approaches are shown side by side. They are different procedures: the Prolozone mixture is Wright's, and ozone-oxygen alone is what Madrid describes.
| Prolozone mixture (per Wright) | Ozone-oxygen only (per Madrid) | |
|---|---|---|
| What goes in | Dr. Wright's pre-mixed solution (formula below), which includes the local anesthetic and B vitamins seen in the demonstration, then ozone gas. | Ozone-oxygen mixture only. |
| Gas volume | Not stated. The hip is a large joint that takes a lot of pressure. The patient says when it is too much and Wright stops. | 10 to 20 mL (section 4.7). The general joint table gives 5 to 20 mL. |
| Concentration | Not stated in the tutorial. | 10 to 20 µg/mL. |
| Approach and needle | Lateral. Palpate the greater trochanter of the femur and move off its edge. 25-gauge by 2-inch needle; a larger needle is sometimes needed. | Not specified by approach. Done under fluoroscopic, ultrasound or anatomical guidance. |
| Schedule | Second injection 10 to 14 days after the first. Results in as few as 3 and as many as 6 to 8 injections. | Once a week until symptoms improve. |
Dr. Wright's pre-mixed solution: how it is made (per 8 mL of mixture)
This is the compounded mixture Dr. Wright used in his protocols. The amounts below are the recipe for making the mixture, taken from the compounded formula sheet, not from the tutorial videos. They are not the amount injected at one site.
| Ingredient | Strength | Amount per 8 mL of mixture |
|---|---|---|
| Methylcobalamin (methyl-B12) | 1 mg/mL | 2 mL |
| Pyridoxine (vitamin B6) | 100 mg/mL | 1 mL |
| Dextrose | 50% | 1 mL |
| Procaine | 2% | 4 mL |
| Total | 8 mL |
- Draw up the solution into a sterile syringe using antiseptic technique (the formula sheet uses a 10 mL syringe).
- Inject the solution at the selected site, using this sheet's own technique and volume.
- Leave the needle in place, remove the syringe, and inject the ozone through the same needle.
How much is injected is not stated in Dr. Wright's hip tutorial, so this sheet gives no solution volume.
This is a compounded pre-mix with a beyond-use date of 90 days refrigerated. The solution is compounded by a pharmacy and requires a prescriber.
Madrid advises placing any local anesthetic so that the ozone does not break it down. Dr. Wright gives his solution first and then the ozone through the same needle. These are two different practices.
What are the best tips when using ozone hip injection?
- Wright chooses the lateral approach because the sciatic nerve runs behind the joint and a posterior injection could pass near it. An anterior approach has a neurovascular bundle.
- He marks the site first. A wince or an ouch at the marked spot tells him he is on target.
- To confirm placement, palpate the same spot again after the anesthetic is in. If it hurts less, the needle was in the right place.
- Tell the patient what to expect. Pressure and fullness while the gas goes in are normal, and the patient should say when it is too much. Wright says an electrical zing is not normal: stop and reposition.
What are the precautions for ozone hip injection, and who should avoid it?
- Sterile technique every time. Madrid says most serious side effects trace back to malpractice, including technique, asepsis and antisepsis. Its reported serious events include septic arthritis of the knee after intra-articular infiltration, abscess after paravertebral injection, and one death from sepsis after a paravertebral infiltration done without proper asepsis (Madrid Declaration on Ozone Therapy, 4th edition (ISCO3, 2025), section 2.5).
- Clean the injection site with alcohol and let it dry before the needle goes through (as Dr. Wright does). Use sterile, single-use syringes and needles, and do not touch the vial adapter once it is out of its package (Wright).
- Draw up nutrient solutions in a hood with needleless vial adapters, as Dr. Wright demonstrates in his overview video. Check that every solution you inject is allowed by your licensing board, as he advises.
- Never inject ozone gas into a vein or an artery. Madrid strongly discourages both because of the risk of air embolism, and lists embolic events after paravertebral and intradiscal injections among its serious adverse events.
- Avoid the posterior approach because of the sciatic nerve. Wright also notes a neurovascular bundle at the anterior approach.
- Stop when the patient says the pressure is too much.
Contraindications
The Madrid Declaration lists these contraindications for systemic ozone (IV and blood). It gives no separate list for intra-articular injection, but many practitioners use the same screening before treating:
- Direct inhalation of ozone gas. The fluid lining the lungs has no antioxidants to buffer it, so inhaled ozone is toxic.
- Glucose-6-phosphate dehydrogenase (G6PD) deficiency (favism, acute hemolytic anemia). Madrid lists it as a contraindication for systemic ozone, but whether it is absolute is debated. MediSkill protocols start low and go slow; see the contraindications article.
- Toxic hyperthyroidism (severe Graves' disease)
- Thrombocytopenia (platelets under 50,000) and severe coagulation disorders
- Severe cardiovascular instability
- Acute alcohol intoxication
- Recent acute myocardial infarction
- Acute massive hemorrhage
- Convulsive states
- Hemochromatosis
- Patients receiving intravenous copper or iron therapy
Pregnancy. Madrid advises avoiding ozone therapy in the first trimester (weeks 0 to 13) and reserves its use in pregnancy for specialists in gynecology and obstetrics.
More detail
Landmarks and steps, as demonstrated by Dr. Wright
- Palpate the greater trochanter of the femur and mark the site just off its edge.
- Clean the site with alcohol and let it dry.
- Insert the 25-gauge by 2-inch needle through the lateral side. Drop the needle down to the site. A wince confirms the spot.
- Inject the solution containing local anesthetic and B vitamins.
- Inject the ozone while the patient reports pressure. Stop when the patient says it is too much.
- Palpate the same spot again to compare tenderness.
Equipment
- 25-gauge by 2-inch needle (larger when needed) and sterile syringes
- Dr. Wright's compounded pre-mixed solution (requires a prescriber), or individual nutrients drawn up in a hood with needleless vial adapters
- Ozone-oxygen gas in a syringe
- Alcohol prep; imaging guidance as Madrid describes
What the studies used
Study doses are listed as printed in each paper and are not Madrid or Wright dosing.
- In 54 people with hip osteoarthritis, ozone at 20 µg/mL, 10 mL, fluoroscopy-guided with a 22G needle, lowered pain (VAS) after 1, 2 or 3 injections two weeks apart. Three injections beat two at 4, 12 and 24 weeks. There was no control group. Three minor injection-site discomforts were reported, with no infection, hematoma or nerve injury (Ozalp 2026).
- In a 325-person knee and hip series (abstract only), hip pain went from 7.33 to 3.3 at one month with 20 µg/mL, 5 to 10 mL, by lateral approach, 25G by 90 mm needle. There was no control group, and the abstract reports two deaths at the one-year follow-up, with the cause not stated (Baeza-Noci 2018).
Hip evidence is thinner than knee: the study summary we drew on has no randomized hip trial, only uncontrolled series. No human study of the classic Prolozone mixture (procaine, vitamins and ozone) is in the study summary we drew on. Trials that add something to ozone used dextrose, somatropin or hypertonic saline, and the evidence for Wright's mixture itself rests on his clinical experience.
