Understanding Bunion Surgery: A Comprehensive Guide
A bunion is a common foot deformity characterized by a bony lump at the base of the big toe. Where the big toe itself is malaligned and pointing towards the second toe, It is known as "hallux valgus". There are many reasons why bunions and hallux valgus may develop. It commonly occurs when there is prolonged pressure on your feet that compress the big toe towards your second toe. Narrow or pointed shoes are a main reason for the formation of bunions. In some patients, unions may limit mobility and cause severe discomfort, particularly while wearing tight shoes.
Conservative methods to treat painful bunions include wearing broad-toe shoes can help reduce pain. The more severe types of bunions may not be successfully managed without surgery. Surgery might be required if non-surgical modalities, such as shoe adjustments, are ineffective at relieving pain.
There are several surgical techniques [1] to manage bunions and hallux valgus. A surgical procedure known as a bunionectomy is intended to remove this bony deformity and relieve related discomfort.
Corrective osteotomies describe surgical procedures to realign a deformed bone. There are many different types of osteotomies that are performed on hallux valgus, and this depends on the severity of the deformity as well as the surgeon’s surgical experience. Understanding the various types of bunion surgeries and their recovery processes is crucial for anyone considering surgery.
What is a Bunionectomy?
A bunionectomy is a surgical treatment that involves the removal of abnormal prominence of the bones. The main goal of hallux valgus surgery is to reduce the pain and restore normal function in the affected foot.
Common symptoms that may lead to the recommendation for surgery include:
- Severe pain that compromises standing or moving about in daily life
- Deformity of the big toe
- Inability to move the big toe properly
- Swelling and inflammation around the base of the big toe
Types of Bunion Surgery
Correction of bunions involves different types of surgeries depending on the severity of symptoms, malalignment, and functional impairment. The type of surgery recommended will depend on the severity of the bunion and the patients’ functional limitations:
- Osteotomy: An osteotomy corrects the bunion by cutting and realigning the bones of the foot. Screws or pins are then inserted into your bones to realign your big toe joint. The most common types include:
- Chevron Osteotomy: This is a V-shaped cut in the bone that allows for realignment. This is utilized for patients with mild to moderate bunions.
- Scarf Osteotomy: This is a Z-shaped cut to reduce the overhanging bone in moderate bunions which enhances both stability and adjustment of the toe.
- Akin Osteotomy: This surgery focuses on correcting the alignment of the first bone in the big toe (proximal phalanx).
- Exostectomy: In this procedure, the surgeon shaves off the bunion, removing the bony bump without correcting any toe deformity. . Exostectomy is rarely used alone, as it does not address the underlying deformity. Surgeons often combine it with an osteotomy to reposition the toe. Exostectomy is typically reserved for cases involving minor bunions. Most patients with bunions have severe deformities which require a corrective osteotomy as well as bunionectomy.
- Arthrodesis: Arthrodesis is the surgical procedure, where two or more bones are fused (joint together) to restore the alignment. The worn out parts of your big toe joint are carefully smoothened out and removed. Screws are placed across the joint to hold the two bones together. This method is typically used for severe cases of arthritis.
3. Lapidus: In this procedure, the surgeon removes the bunion and realigns the foot by fusing the joint between the first metatarsal bone (the long bone in the middle of the foot) and the medial cuneiform (one of the small bones where the foot meets the ankle). This fusion stabilizes the toe and corrects the deformity. The Lapidus procedure is typically recommended for individuals with severe bunions, as well as those with hypermobility in the foot, where the bunion causes the toe to become unstable or move excessively. It is also an effective option for younger patients with bunions.
4. Minimally Invasive Bunion Surgery: It is a modern approach that uses smaller incisions to reduce recovery time and scarring. Minimally invasive bunion surgery offers many of the same benefits as traditional procedures but with smaller incisions, reduced recovery time, and fewer complications. It does not require special instrumentation and is performed under direct vision without fluoroscopy (Real-time X-ray imaging).

After surgery, patients can expect some swelling and pain after any form of surgery. This is routinely, managed with medication, foot elevation and rest. Protective measures like special shoes or boots may also be used to stabilize the foot. Dr Mizan uses a forefoot offloading shoe so that patients may walk immediately while their toes are protected. It is important to avoid placing your full body weight on the operated foot as it takes several weeks for the bones to heal and recover.
In the initial weeks, patients will need assistance walking, such as crutches or walkers. During this period resting and elevating your foot will be crucial. Follow-up appointments will be scheduled to monitor healing and care for the stitches. X-rays may be performed at these appointments to monitor the bone healing progress.
Long-term Recovery (Several Months)Recovery can take several months, during which you will gradually return to regular activities. Physical therapy may be recommended to regain strength and flexibility. Factors affecting recovery time include age, overall health, and type of surgery performed.
Full RecoveryMost patients return to their full physical function within 3 to 6 months. This will include low impact sports such as jogging, cycling and swimming. Recovery and function also depends on patients general physical abilities, body weight and the type of surgery they received. Physiotherapy and rehabilitation are important aspects of recovery after surgery. They are aimed at maintaining muscle strength, joint flexibility and range of motion.
