Minimally Invasive Bunion Surgery vs Lapiplasty: Understanding the Differences

Minimally invasive bunion surgery and the Lapiplasty procedure are both techniques used to treat bunions, but they differ in their approach, surgical methods, and outcomes. At North Texas Foot & Ankle, we want patients to be well-versed in both options. As we explain to our patients, the best procedure for one person is not necessarily the best for another. Some procedures allow you to walk much sooner meaning you may not have to use crutches for as long, and some require longer non-weightbearing. Depending on your foot type and symptoms, a specific procedure may be warranted over another.

Here are some key differences between the two main types of bunion procedures:

Surgical Approach

Minimally Invasive Bunion Surgery: This approach involves making smaller incisions and using specialized instruments to correct the bunion deformity. Surgeons typically use arthroscopy or other minimally invasive techniques to realign the bones and address soft tissue issues.

Lapiplasty: Lapiplasty is a specific type of minimally invasive bunion surgery that involves creating a “triple-cut” osteotomy, which means cutting the bone in three planes. This allows for more comprehensive correction of the deformity.

Bone Realignment

Minimally Invasive Bunion Surgery: Traditional minimally invasive techniques focus on correcting the bunion by addressing bone alignment and soft tissue imbalances. However, they may not provide the same level of stability as the Lapiplasty procedure.

Lapiplasty: Lapiplasty aims to correct the three-dimensional deformity of the metatarsal bone and provide more stable and anatomically accurate correction. It not only addresses the misalignment of the bone but also helps to stabilize the entire bone structure.

Fixation and Stability

Minimally Invasive Bunion Surgery: This approach may use screws, wires, or other fixation methods to hold the bones in the corrected position. However, the stability achieved can vary based on the technique and surgeon’s skill.

Lapiplasty: Lapiplasty uses specialized instrumentation and titanium plates with a “truss” design to secure the bones in the corrected position. This truss-like fixation provides enhanced stability and reduces the risk of recurrence.

Weight-Bearing and Recovery

Minimally Invasive Bunion Surgery: Recovery time can vary, but patients often transition to weight-bearing relatively quickly. However, the degree of weight-bearing allowed might depend on the specific surgical technique used.

Lapiplasty: Patients are typically allowed to bear weight on the treated foot earlier in the recovery process compared to some traditional surgical methods. The stability provided by the Lapiplasty fixation system contributes to this accelerated weight-bearing timeline.

Risk of Recurrence

Minimally Invasive Bunion Surgery: Recurrence rates for bunions can vary based on the specific technique used and the individual patient’s foot structure. Some minimally invasive techniques may have higher recurrence rates compared to Lapiplasty.

Lapiplasty: The Lapiplasty procedure is designed to address the root cause of bunions by correcting the three-dimensional deformity and providing stable fixation. As a result, it has been reported to have lower recurrence rates compared to some other methods.
