Bunions are bony bumps that form on the side of the big toe joint or baby toe joint (these are commonly called ?bunionettes? or ?tailor?s bunions?). Bunions most commonly result from one or more of the following factors: genetics, faulty foot mechanics like over-pronation, and/or long periods of time spent in improperly fitting footwear. Bunions can start with audible clicking (called ?crepitus?) and/or stiffness in the affected joint which indicates that the joint surfaces are rubbing together improperly. This may progress to include inflammation, degeneration of the surfaces of the joint, deformity (including bone growth at the joint line and displacement of the toe) and ultimately, loss of range of motion in the joint.
The main cause of bunions is a mechanical imbalance in the feet which is usually inherited. The mechanical imbalance is known as overpronation, where the feet roll in towards the arch and big toe. This added weight and stress transfer towards the big toe, causes instability in the structures of this area and a bunion develops.
SymptomsJust because you have a bunion does not mean you will necessarily have pain. There are some people with very severe bunions and no pain and people with mild bunions and a lot of pain. Symptoms for a bunion may include pain on the inside of your foot at the big toe joint, swelling on the inside of your foot at the big toe joint, appearance of a “bump” on the inside edge of your foot. The big toe rolling over to one side. Redness on the inside of your foot at the big toe joint. Numbness or burning in the big toe (hallux). Decreased motion at the big toe joint. Painful bursa (fluid-filled sac) on the inside of your foot at the big toe joint. Pain while wearing shoes – especially shoes too narrow or with high heels. Joint pain during activities. Other conditions which may appear with bunions include Corns in between the big toe and second toe. Callous formation on the side or bottom of the big toe or big toe joint. Callous under the second toe joint. Pain in the second toe joint.
A simple visual exam is all it will take for your doctor to determine whether you have a bunion. He or she may also ask you to move your big toe in order to ascertain your range of motion. Your doctor may also look for any inflammation, redness, or pain. X-rays can help your doctor determine the severity and cause of the bunion. Your doctor may also ask you questions about your footwear, the symptoms you are experiencing, and if other family members also suffer from the condition. All these factors will help him or her diagnose you properly.
Non Surgical Treatment
Patients with a painful bunion may benefit from four to six physical therapy treatments. Your therapist can offer ideas of shoes that have a wide toe box (mentioned earlier). The added space in this part of the shoe keeps the metatarsals from getting squeezed inside the shoe. A special pad can also be placed over the bunion. Foot orthotics may be issued to support the arch and hold the big toe in better alignment. These changes to your footwear may allow you to resume normal walking immediately, but you should probably cut back on more vigorous activities for several weeks to allow the inflammation and pain to subside. Treatments directed to the painful area help control pain and swelling. Examples include ultrasound, moist heat, and soft-tissue massage. Therapy sessions sometimes include iontophoresis, which uses a mild electrical current to push anti-inflammatory medicine to the sore area. This treatment is especially helpful for patients who can’t tolerate injections.
Larger bunions often require the surgeon to move the entire bone over (1st metatarsal). This is accomplished by a cut or fusion at the bottom of the bone. The former technique, is called the Lapidus bunionectomy. Additionally, the repositioned bone is held in place with one or two surgical screws.
