Advanced bunion correction with minimal downtime and faster recovery. At Annapolis Foot & Ankle Center, Dr. Eric Harmelin offers state-of-the-art minimally invasive bunion surgery for patients seeking effective bunion correction with reduced pain, smaller scars, and quicker return to activities.
What is Minimally Invasive Bunion Surgery?
Minimally invasive bunion surgery (MICA - Minimally Invasive Chevron and Akin) is an advanced surgical technique that corrects bunion deformities through 3-5 small incisions, each less than 1 centimeter in length. Unlike traditional open surgery that requires large incisions of 3-5 inches, this innovative approach uses specialized instruments and fluoroscopic (real-time X-ray) guidance to precisely realign the bones of the big toe.
How the Procedure Works
During minimally invasive bunion surgery, Dr. Harmelin:
- Makes tiny incisions: 3-5 small puncture wounds through the skin
- Uses specialized burrs: Water-cooled cutting instruments instead of traditional saws
- Realigns bones precisely: Cuts and repositions the first metatarsal and big toe bones
- Secures with screws: Places titanium screws through the small incisions
- Monitors with fluoroscopy: Real-time X-ray guidance ensures optimal positioning
Types of Minimally Invasive Bunion Procedures
PECA (Percutaneous Chevron Akin) for Mild to Moderate Bunions
The PECA technique involves cutting both the first metatarsal bone (chevron osteotomy) and the big toe bone (Akin osteotomy) to correct the bunion alignment. This procedure is ideal for patients with mild to moderate bunion deformities.
Recovery timeline:
- Immediate weight bearing after 24 hours
- Return to normal shoes in 6 weeks
- Full activity resumption in 8-10 weeks
Minimally Invasive Lapidus for Severe Bunions
For severe bunions or those with instability, the minimally invasive Lapidus technique fuses the joint between the first metatarsal and medial cuneiform bones while also correcting the big toe position. This provides more powerful correction for complex deformities.
Recovery timeline:
- Weight bearing begins 2-4 weeks post-surgery
- Return to normal shoes in 8 weeks
- Full activity resumption in 10-12 weeks
Benefits of Minimally Invasive Bunion Surgery
| Advantage | Minimally Invasive | Traditional Open Surgery |
|---|---|---|
| Incision Size | 3-5 small punctures (<1 cm each) | Large incision (3-5 inches) |
| Pain Level | Significantly reduced | More extensive post-operative pain |
| Weight Bearing | Immediate to 24 hours | 2-6 weeks non-weight bearing |
| Return to Normal Shoes | 6-8 weeks | 10-12 weeks |
| Scarring | Barely visible tiny marks | Prominent surgical scar |
| Infection Risk | Lower risk | Higher risk due to larger incisions |
| Swelling | Minimal soft tissue disruption | Significant swelling from tissue damage |
Understanding Bunions (Hallux Valgus)
A bunion is a foot deformity caused by malalignment of the foot bones, not simply a "growth" of bone. The condition, medically known as hallux valgus, develops when the first metatarsal bone deviates inward while the big toe angles toward the second toe, creating the characteristic bump on the inside of the foot.
Common Causes of Bunions
- Genetics: Inherited foot structure and biomechanics
- Footwear: High heels and narrow toe boxes
- Foot mechanics: Flat feet and ligament laxity
- Medical conditions: Rheumatoid arthritis and inflammatory disorders
- Age: Progressive worsening over time due to soft tissue changes
When to Consider Surgery
Bunion surgery may be recommended when:
- Conservative treatments have failed to provide relief
- Pain interferes with daily activities
- Difficulty fitting into shoes
- Progressive deformity affecting toe function
- Development of secondary conditions (hammertoes, arthritis)
Am I a Candidate for Minimally Invasive Bunion Surgery?
Ideal Candidates
Minimally invasive bunion surgery works best for patients with:
- Mild to moderate bunions: Bunion angle typically less than 40 degrees
- Good bone quality: Adequate bone density for screw fixation
- Realistic expectations: Understanding of recovery process and limitations
- Healthy circulation: Good blood flow for proper healing
- Stable foot structure: Minimal associated deformities
When Traditional Surgery May Be Better
Open surgery may be recommended for:
- Severe deformities: Bunion angles greater than 40 degrees
- Arthritis in the big toe joint: Requiring joint fusion
- Osteoporosis: Weak bones that may not hold screws securely
- Complex foot deformities: Flat feet requiring additional procedures
- Previous failed bunion surgery: Revision cases with scar tissue
The Surgical Process at Annapolis Foot & Ankle Center
Pre-Operative Evaluation
Dr. Harmelin conducts a comprehensive assessment including:
- Physical examination: Evaluation of foot structure and range of motion
- Weight-bearing X-rays: Measurement of bunion angles and bone alignment
- Medical history review: Assessment of overall health and medications
- Gait analysis: Understanding of foot function and biomechanics
- Treatment planning: Selection of optimal surgical technique
Day of Surgery
Minimally invasive bunion surgery is performed as an outpatient procedure:
- Anesthesia: Local anesthesia with sedation for comfort
- Duration: Typically 45-60 minutes per foot
- Monitoring: Continuous fluoroscopic guidance
- Immediate care: Application of surgical dressing and post-operative shoe
- Discharge: Same-day release with walking capability
Recovery and Post-Operative Care
Immediate Post-Operative Period (0-2 Weeks)
- Weight bearing: Immediate or within 24 hours as directed
- Surgical shoe: Special post-operative footwear protection
- Elevation: Keep foot elevated 80% of time in first week
- Wound care: Keep dressings dry and clean
- Activity: Limited walking, no strenuous activity
Early Recovery (2-6 Weeks)
- Follow-up visits: Regular monitoring with X-rays
- Gradual activity increase: Progressive weight bearing
- Swelling management: Continued elevation and ice as needed
- Range of motion: Gentle toe exercises to prevent stiffness
- Work return: Desk jobs typically 1-2 weeks, standing jobs 2-4 weeks
Full Recovery (6+ Weeks)
- Normal shoes: Gradual transition to regular footwear
- Exercise resumption: Progressive return to sports and activities
- Final healing: Continued bone remodeling for 3-6 months
- Long-term care: Proper footwear and foot care maintenance
Success Rates and Patient Satisfaction
Minimally invasive bunion surgery demonstrates excellent success rates with high patient satisfaction. Studies show:
- 85% of patients report "good" to "very good" outcomes
- 10% report satisfactory results with minor limitations
- Reduced pain medication use compared to traditional surgery
- Better range of motion preservation of big toe joint
- Lower complication rates due to minimal tissue disruption
- Faster return to activities with improved quality of life
Potential Risks and Complications
While minimally invasive bunion surgery has a lower complication rate than traditional surgery, potential risks include:

Frequently Asked Questions
What is minimally invasive bunion surgery?
Minimally invasive bunion surgery (MICA) corrects bunion deformities through 3-5 small incisions less than 1 centimeter each, using specialized instruments and fluoroscopic guidance. This technique causes less tissue disruption, reduced pain, and faster recovery compared to traditional open surgery.
How long is recovery from minimally invasive bunion surgery?
Recovery from minimally invasive bunion surgery is typically 6-8 weeks for return to normal shoes, compared to 10-12 weeks for traditional surgery. Most patients can bear weight immediately and return to work within 2 weeks, depending on their occupation.
Am I a candidate for minimally invasive bunion surgery?
Candidates for minimally invasive bunion surgery include patients with mild to moderate bunions, good bone quality, and realistic expectations. Severe deformities, significant arthritis, or osteoporosis may require traditional open surgery for optimal results.
How painful is minimally invasive bunion surgery?
Minimally invasive bunion surgery is significantly less painful than traditional surgery due to smaller incisions and less tissue disruption. Most patients require only over-the-counter pain medication for 3-5 days post-surgery.
Can I walk immediately after surgery?
Most patients can bear weight immediately or within 24 hours after minimally invasive bunion surgery while wearing a special post-operative shoe. This is a major advantage over traditional surgery, which often requires weeks of non-weight bearing.
Will my bunion come back after surgery?
The recurrence rate for minimally invasive bunion surgery is very low when performed on appropriate candidates. Wearing proper footwear and following post-operative instructions significantly reduces the risk of bunion return.
How small are the scars?
Scars from minimally invasive bunion surgery are barely visible, typically appearing as small dots or lines less than 1 centimeter each. These fade significantly over time and are often difficult to detect.
When can I return to sports and exercise?
Return to sports and exercise varies by activity level and healing progress. Most patients can resume low-impact activities at 6-8 weeks and high-impact sports at 10-12 weeks, always with Dr. Harmelin's clearance.
Do I need physical therapy after surgery?
Formal physical therapy is often not required after minimally invasive bunion surgery. Dr. Harmelin will provide specific exercises and instructions for home rehabilitation to maintain flexibility and strength.
How long do the surgical screws stay in my foot?
The titanium screws used in minimally invasive bunion surgery are designed to remain permanently in your foot. They are biocompatible and rarely cause problems or require removal.
