The Weil Osteotomy (WO) is a type of surgery designed to fix foot pain caused by problems with the bones in the forefoot, particularly the metatarsals (the bones behind your toes). This condition, known as metatarsalgia, happens when there’s too much pressure on the balls of the feet, often due to the bones not being properly aligned. The surgery works by shortening one of the metatarsal bones to relieve pressure and pain.
How Common It Is and Who Gets It? (Epidemiology)
Metatarsalgia and related conditions that lead to pain in the forefoot, particularly the metatarsals, are common in individuals who have altered foot mechanics or those who place excess pressure on the balls of their feet. This can be caused by improper footwear, foot deformities, or specific activities like running. The Weil Osteotomy is especially effective in patients with misaligned metatarsals that cause pain and discomfort.
Why It Happens – Causes (Etiology and Pathophysiology)
Metatarsalgia occurs when the metatarsals, specifically the third one, are too long compared to the other bones. This imbalance increases pressure on the balls of the feet, causing pain, discomfort, and difficulty walking. In some cases, conditions like rheumatoid arthritis or trauma may also contribute to this condition. The Weil Osteotomy addresses this by shortening the metatarsal and realigning the bones to better distribute pressure.
How the Body Part Normally Works? (Relevant Anatomy)
The metatarsal bones in the foot play a vital role in supporting the body’s weight and helping in walking and balance. The first and second metatarsals are generally more stable, while the third one, if too long, can cause excessive pressure in the ball of the foot, leading to pain. The Weil Osteotomy corrects this by shortening the metatarsal, allowing for better foot mechanics and reduced pressure.
What You Might Feel – Symptoms (Clinical Presentation)
Common symptoms of metatarsalgia include:
- Pain: Typically in the ball of the foot, worsening with walking or standing.
- Tenderness: Swelling and tenderness over the affected metatarsal.
- Difficulty Walking: The pain makes it hard to walk normally, causing discomfort and altered gait.
How Doctors Find the Problem? (Diagnosis and Imaging)
Diagnosis of metatarsalgia is made through:
- Physical Examination: Assessing foot alignment and pressure points in the ball of the foot.
- X-rays: These help identify the length of the metatarsals and detect any deformities.
- Other Imaging: In some cases, MRIs may be used to get a better view of the soft tissue and joint involvement.
Classification
Metatarsalgia is often classified based on the severity of the condition and the extent of misalignment of the metatarsals. The Weil Osteotomy is most commonly used in cases where one or more metatarsals are significantly out of alignment, causing pain and dysfunction.
Other Problems That Can Feel Similar (Differential Diagnosis)
Conditions like Morton’s neuroma, sesamoiditis, or fractures can present with similar symptoms of foot pain. Morton’s neuroma, in particular, can cause pain in the ball of the foot and is often mistaken for metatarsalgia. Imaging and physical examination are essential to differentiate these conditions.
Treatment Options
Non-Surgical Care:
-
- Footwear Modifications: Soft, cushioned shoes to reduce pressure on the metatarsals.
- Orthotics: Custom insoles to redistribute pressure and provide arch support.
- Physical Therapy: Strengthening exercises for the foot and ankle to improve alignment.
- Pain Management: Use of NSAIDs or corticosteroid injections to reduce inflammation.
Surgical Care:
-
- Weil Osteotomy: The primary surgical option for correcting the length of the metatarsal, realigning the bones, and relieving pressure on the foot.
Recovery and What to Expect After Treatment
After Weil Osteotomy surgery, patients typically wear a special shoe or boot to protect the foot while it heals. Weight-bearing may be restricted for several weeks, and physical therapy is encouraged to restore mobility and prevent stiffness. Full recovery can take several months, depending on the extent of the surgery and individual healing progress.
Possible Risks or Side Effects (Complications)
- General Risks: Infection, scarring, and nerve injury are potential risks of any surgery.
- Specific Risks: Floating toes (stiff toes that don’t touch the ground), failure of the osteotomy, or issues with healing.
- Postoperative Care: The risk of complications can be minimized with proper aftercare, including following rehabilitation instructions and wearing protective footwear as prescribed.
Long-Term Outlook (Prognosis)
The prognosis for Weil Osteotomy is generally excellent. Most patients experience significant pain relief and improved foot function. However, the long-term success depends on post-operative rehabilitation, weight management, and avoiding high-stress activities during recovery.
Out-of-Pocket Cost
Medicare
CPT Code 28308 – Weil Osteotomy (Metatarsal Osteotomy for Structural Correction): $130.95
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 generally cover that remaining 20%, minimizing or eliminating out-of-pocket expenses for Medicare-approved surgeries. These plans work with Medicare to fill the coverage gap and reduce your financial responsibility.
If you have Secondary Insurance, such as TRICARE, an Employer-Based Plan, or Veterans Health Administration coverage, it acts as a secondary payer. These plans usually cover any remaining balance, including coinsurance or small deductibles, which typically range from $100 to $300, depending on your plan and provider network.
Workers’ Compensation
If your Weil osteotomy is required due to a work-related injury or condition, Workers’ Compensation will cover all related medical expenses, 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 Weil osteotomy is needed because of an automobile accident or foot injury, No-Fault Insurance will typically cover the full cost of treatment, including surgery and recovery. The only potential out-of-pocket cost may be a small deductible or co-payment depending on your policy.
Example
Samantha Lewis required a Weil osteotomy (CPT 28308) to correct a metatarsal deformity and relieve pain in her foot. Her estimated Medicare out-of-pocket cost was $130.95. Since Samantha had supplemental insurance through Blue Cross Blue Shield, her remaining balance was fully covered, leaving her with no out-of-pocket expenses for the procedure.

Summary and Takeaway
The Weil Osteotomy is a highly effective surgery for relieving foot pain caused by metatarsalgia, particularly when a long metatarsal is causing excess pressure on the ball of the foot. The procedure offers significant pain relief, improves foot function, and allows patients to return to normal activities after full recovery. While risks exist, the procedure is generally safe, with excellent outcomes when proper post-operative care and rehabilitation are followed.
Clinical Insight & Recent Findings
A recent study reviewed 62 publications to understand why “floating toes” — a condition where toes fail to touch the ground after a Weil osteotomy — occur and how they can be prevented. The review identified several contributing factors, including changes in the mechanical structure of the foot, downward shifting of the metatarsophalangeal joint’s rotation center, tendon and ligament imbalance, and surgical factors such as excessive bone shortening or scarring.
Modified and triple Weil osteotomies, which better preserve the natural metatarsal alignment (“Maestro parabola”), significantly reduce these complications. The study also highlighted that adding flexor tenodesis or combining the procedure with proximal interphalangeal (PIP) joint arthrodesis can improve long-term outcomes.
Proper preoperative planning, surgical precision, and structured postoperative rehabilitation were emphasized as key to preventing floating toes and restoring normal foot mechanics. (“Study on floating toe prevention after Weil osteotomy – see PubMed.”)
Who Performs This Treatment? (Specialists and Team Involved)
Orthopedic surgeons specializing in foot and ankle surgery typically perform the Weil Osteotomy. A multidisciplinary team, including physical therapists and rehabilitation specialists, may also be involved in post-operative care.
When to See a Specialist?
If you experience persistent pain in the ball of your foot that doesn’t improve with conservative treatments like orthotics or rest, it’s important to see a specialist to determine if surgery is needed.
When to Go to the Emergency Room?
Seek emergency care if you experience severe pain, swelling, or signs of infection following surgery.
What Recovery Really Looks Like?
Recovery from the Weil Osteotomy requires several months, with early weeks focused on protecting the foot, followed by physical therapy to restore strength and mobility.
What Happens If You Ignore It?
Ignoring metatarsalgia can lead to persistent pain, altered gait, and further damage to the foot. Early surgical intervention like the Weil Osteotomy can prevent worsening symptoms and improve long-term outcomes.
How to Prevent It?
Prevent metatarsalgia by wearing well-fitting shoes with adequate cushioning, managing body weight, and avoiding activities that place excessive pressure on the balls of the feet.
Nutrition and Bone or Joint Health
A diet rich in calcium and vitamin D is important for bone health, and maintaining a healthy weight will reduce stress on the feet.
Activity and Lifestyle Modifications
After surgery, low-impact exercises are ideal to maintain fitness while allowing the foot to heal. Avoid high-impact activities until the foot has fully recovered.
