The Chevron Bunionectomy is a surgical procedure used to treat bunion deformities, primarily targeting the alignment of the big toe. It involves making a V-shaped cut in the bone of the first metatarsal, then shifting it into a more natural position to relieve pain, reduce the bony bump, and improve foot function. This surgery is considered minimally invasive and is effective for correcting mild to moderate bunions.
How Common It Is and Who Gets It? (Epidemiology)
Bunions are common, particularly in adults, and affect more women than men, likely due to wearing narrow-toed shoes and high heels. It is estimated that approximately 23% of adults will experience bunions by the time they reach their 60s. The condition is more prevalent in people with abnormal foot structure, a family history of bunions, or those who engage in repetitive stress on the feet.
Why It Happens – Causes (Etiology and Pathophysiology)
A bunion, or hallux valgus, forms when the big toe gradually drifts toward the second toe, causing the first metatarsal to protrude. Common causes include:
- Genetic predisposition to abnormal foot mechanics.
- Tight, narrow shoes that force the toes into unnatural positions.
- Arthritis or other joint issues affecting the foot.
How the Body Part Normally Works? (Relevant Anatomy)
The first metatarsophalangeal joint (MTP joint) is the connection between the first metatarsal bone and the proximal phalanx of the big toe. It allows for necessary movement during walking, running, and other activities. A bunion occurs when this joint is misaligned, leading to a protruding bump and limiting toe movement.
What You Might Feel – Symptoms (Clinical Presentation)
Symptoms of a bunion include:
- Pain at the base of the big toe, exacerbated by pressure from shoes.
- A visible bump at the first MTP joint.
- Decreased range of motion in the big toe.
- Swelling or redness around the joint.
- Difficulty finding shoes that fit comfortably due to the bunion.
How Doctors Find the Problem? (Diagnosis and Imaging)
Diagnosis involves:
- Physical examination to assess the alignment of the big toe.
- X-rays to evaluate the angle between the first metatarsal and the phalanx and determine the extent of the deformity.
- MRI may be used in certain cases to evaluate soft tissue damage or inflammation.
Classification
Bunions are classified based on severity:
- Mild bunion: Slight misalignment, minimal pain.
- Moderate bunion: Noticeable deformity, causing discomfort and difficulty walking.
- Severe bunion: Significant misalignment with pain and limited movement.
Other Problems That Can Feel Similar (Differential Diagnosis)
Other conditions that may mimic a bunion include:
- Arthritis in the MTP joint.
- Gout affecting the toe joint.
- Hammer toe or claw toe deformities.
Treatment Options
Non-Surgical Care
- Wearing wide-toed shoes to reduce pressure on the bunion.
- Padding or spacers to protect the bunion and separate the first and second toes.
- Orthotics to redistribute foot pressure and improve alignment.
- Physical therapy to strengthen foot muscles and improve flexibility.
Surgical Care
- Chevron Bunionectomy, involving a V-shaped cut in the bone to realign the big toe.
- Arthrodesis (joint fusion) for advanced cases where mobility is no longer feasible.
- Minimally invasive techniques for quicker recovery and smaller incisions.
Recovery and What to Expect After Treatment
Recovery typically involves:
- Non-weight bearing for 2 to 6 weeks to allow proper healing.
- Physical therapy to regain movement and strength in the foot.
- Pain management with medications and elevation of the foot.
- Most patients return to normal activities within 6 to 8 weeks, with full recovery potentially taking up to a year.
Possible Risks or Side Effects (Complications)
Possible risks include:
- Infection at the surgical site.
- Recurrent bunion if the misalignment is not corrected properly.
- Nerve damage leading to numbness or tingling.
- Stiffness or limited mobility in the big toe.
- Nonunion or delayed bone healing in rare cases.
Long-Term Outlook (Prognosis)
The Chevron Bunionectomy has a high success rate, with most patients experiencing:
- Pain relief and improvement in foot function.
- Preserved mobility in the big toe.
- Most patients can return to normal footwear and activities within 6 to 8 weeks.
Out-of-Pocket Costs
Medicare
CPT Code 28296 – Chevron Bunionectomy: $200.67
Medicare Part B typically covers 80% of the approved cost for this procedure once your annual deductible has been met, leaving you responsible for the remaining 20%. Supplemental Insurance plans such as Medigap, AARP, or Blue Cross Blue Shield typically cover the remaining 20%, reducing or eliminating out-of-pocket expenses for Medicare-approved surgeries. These plans are designed to work alongside Medicare to fill the coverage gap.
If you have Secondary Insurance such as TRICARE, an Employer-Based Plan, or Veterans Health Administration coverage, it will act as a secondary payer. These plans usually cover any remaining balance, including coinsurance or small deductibles, which generally range from $100 to $300 depending on your plan and provider network.
Workers’ Compensation
If your Chevron bunionectomy is required due to a work-related injury, Workers’ Compensation will cover all treatment costs, including surgery, rehabilitation, and follow-up care. You will not have any out-of-pocket expenses, as the employer’s insurance carrier directly covers all approved treatments.
No-Fault Insurance
If your bunionectomy surgery is related to an automobile accident, No-Fault Insurance will typically cover the full cost of treatment, including surgery and follow-up care. The only potential out-of-pocket cost may be a small deductible or co-payment depending on your policy.
Example
Emma Davis underwent a Chevron bunionectomy (CPT 28296) to correct her bunion deformity, with an estimated Medicare out-of-pocket cost of $200.67. Since Emma had supplemental insurance through Blue Cross Blue Shield, her remaining 20% balance was fully covered, leaving her with no out-of-pocket expenses for the procedure.
Frequently Asked Questions (FAQ)
Q. What is the Chevron Bunionectomy?
A. The Chevron Bunionectomy is a surgical procedure used to treat bunions by making a V-shaped cut in the bone of the first metatarsal, realigning it to relieve pain, improve function, and reduce the size of the bunion.
Q. How is the Chevron Bunionectomy performed?
A. During the surgery, the surgeon makes a small incision at the side of the big toe, cuts the first metatarsal bone in a V-shape, realigns the bone, and may use screws or plates to stabilize it while it heals.

Summary and Takeaway
The Chevron Bunionectomy is a minimally invasive surgery that provides a highly effective solution for correcting bunions. It offers faster recovery, less pain, and preserved toe movement compared to traditional bunion surgeries, making it an attractive option for many patients.
Clinical Insight & Recent Findings
A recent study compared minimally invasive (MIS) Chevron and Akin bunionectomy with the modified Lapidus procedure in patients with similar bunion severity. Both surgeries produced excellent radiographic correction and similar patient-reported outcomes.
The MIS Chevron technique had shorter operative times and allowed immediate weightbearing, but showed a slightly higher rate of hardware issues and nonunion compared to Lapidus.
Overall, both procedures were safe and effective for mild to moderate bunions, with MIS offering faster recovery but Lapidus remaining preferred for more complex deformities. (“Study comparing minimally invasive Chevron bunionectomy with Lapidus surgery – see PubMed”)
Who Performs This Treatment? (Specialists and Team Involved)
The Chevron Bunionectomy is typically performed by orthopedic surgeons specializing in foot and ankle surgery. The surgical team may include podiatrists and physical therapists to assist with post-operative rehabilitation.
When to See a Specialist?
If you experience persistent pain, difficulty walking, or problems with shoe fitting due to a bunion, it’s important to consult with an orthopedic surgeon to evaluate whether surgical intervention like the Chevron Bunionectomy is appropriate.
When to Go to the Emergency Room?
Seek emergency care if:
- Severe pain at the surgical site.
- Signs of infection such as fever, redness, or drainage.
- Inability to move the toe or bear weight after surgery.
What Recovery Really Looks Like?
After surgery, patients typically wear a walking boot and avoid weight-bearing for 2 to 6 weeks. Full recovery, including the return to regular shoes and activities, can take up to 6 to 8 weeks.
What Happens If You Ignore It?
If left untreated, a bunion can cause chronic pain, difficulty walking, and worsening deformity. Over time, the condition may become more difficult to treat, requiring more invasive procedures.
How to Prevent It?
Prevention includes:
- Wearing properly fitted shoes with a wide toe box.
- Avoiding high heels and tight shoes that force the toes into unnatural positions.
- Early treatment with orthotics for structural issues like flat feet.
Nutrition and Bone or Joint Health
Maintaining healthy calcium, vitamin D, and protein intake supports joint health and helps promote healing after surgery.
Activity and Lifestyle Modifications
Post-surgery, patients should avoid high-impact activities until the foot has fully healed. Gradually resuming physical activities with the help of physical therapy will restore strength and flexibility.
