A bunion, medically known as hallux valgus, is a bony bump that forms on the joint of the big toe. This deformity develops when some of the bones in the front part of your foot move out of place. Bunions cause the tip of the big toe to get pulled inward, which forces the joint at the base of the big toe to stick out. The joint can become sore, red, and swollen over time. Bunions may affect foot mechanics, potentially causing pain during walking or when wearing certain types of shoes.
What Causes a Bunion?
While the exact cause varies, bunions are largely the result of an inherited foot type. The bunion itself is not inherited, but certain foot shapes that make a person prone to developing a bunion are. Wearing shoes that crowd the toes does not directly cause bunions, but it can make the deformity get worse. Foot injuries and congenital deformities may also contribute to the development of this condition.
You should consult a podiatrist if you have ongoing big toe or foot pain that interferes with your daily life. A specialist can evaluate the structure of your foot and determine the severity of the deformity. The most obvious sign of a bunion is a bulging bump on the outside of your big toe, especially if you experience other joint symptoms. Some individuals experience persistent or intermittent pain, and restricted movement of the big toe is common as the condition advances. Bunions often cause corns and calluses to develop from the first and second toes rubbing against each other.
What Treats Bunions?
Treatment plans for bunions focus on relieving pressure and pain, as the deformity itself will not reverse without surgical intervention. Conservative management can stop the deformity from progressing while managing pain. Prescription orthotic devices are shoe inserts customized to the unique structure of your foot to redistribute pressure and support walking. By stabilizing the joint, custom orthotics slow the progression of the deformity and alleviate discomfort during movement.
Physical therapy exercises help maintain joint mobility and strengthen the muscles around the foot and ankle. These exercises work as part of a larger comprehensive condition management plan, and therapy sessions offer expert guidance through personalized stretches. Physical therapy cannot remove the bunion, but it can improve foot function and reduce stiffness.
For acute flare-ups involving significant inflammation, a podiatrist might recommend corticosteroid injections. These injections are administered directly into the toe joint to reduce swelling and pain temporarily. Steroid injections manage symptoms; they do not change the structural deformity. Pain injections often improve an individual’s ability to participate more fully in physical therapy.
When Is Surgery Necessary?
Surgery is recommended when conservative treatments no longer provide relief, especially when pain interferes with daily life. The goal of surgery is to realign the bone, ligaments, tendons, and nerves so the big toe can be brought back to its correct position. A modern innovation in bunion care is minimally invasive surgery techniques. These techniques offer smaller incisions during surgery, which often improve healing times and recovery outcomes.
Minimally Invasive Osteotomy
An osteotomy is the most common type of bunion surgery, and more surgeons are utilizing minimally invasive techniques during it. A minimally invasive osteotomy involves making small incisions to access the bone. After some bone is removed, pins or screws are placed to fully reposition the toe joint, which realigns everything. Incisions are smaller, so there is often less damage to soft tissues, which often leads to faster recovery times. Minimally invasive techniques also cause less postoperative pain compared to traditional surgical methods.
Other Bunion Surgeries
Depending on the severity of the bunion, other surgical options may be required. An exostectomy involves removing the bump from the toe joint, though this is rarely done alone as it does not realign the joint. Arthrodesis removes damaged joint surfaces and inserts screws, wires, or plates to hold the surfaces together until the bones heal. This procedure is generally reserved for severe bunions or cases where arthritis is present in the joint.
