When your big toe is angled towards the second toe, the deformity is called a bunion (hallux valgus). This causes a bump on the side at the base of the big toe. In addition there is often thickening of the skin and tissues next to the affected joint. The thickened skin and tissues may become inflamed, swollen and painful. Sometimes a fluid-filled sac (bursa) develops over the joint.
Shoes with narrow toes can trigger a bunion, but they?re not the underlying cause. Bunions run in families, because foot type (shape and structure) is hereditary, and some types are more prone to bunions than others. Low arches, flat feet, and loose joints and tendons all increase the risk. The shape of the metatarsal head (the top of the first metatarsal bone) also makes a difference: if it?s too round, the joint is less stable and more likely to deform when squeezed into shoes with narrow toes.
A bulging bump on the outside of the base of your big toe. Swelling, redness or soreness around your big toe joint aggravated by footwear. Red, calloused skin along the inside edge of the big toe. Corns or calluses under the ball of the foot or where the first and second toes overlap. Persistent or intermittent pain. Restricted movement of your big toe.
Your doctor will ask questions about your past health and carefully examine your toe and joint. Some of the questions might be: When did the bunions start? What activities or shoes make your bunions worse? Do any other joints hurt? The doctor will examine your toe and joint and check their range of motion. This is done while you are sitting and while you are standing so that the doctor can see the toe and joint at rest and while bearing weight. X-rays are often used to check for bone problems or to rule out other causes of pain and swelling. Other tests, such as blood tests or arthrocentesis (removal of fluid from a joint for testing), are sometimes done to check for other problems that can cause joint pain and swelling. These problems might include gout , rheumatoid arthritis , or joint infection.
Non Surgical Treatment
There are two ways to treat this pathological foot conditions, conservatively and surgically. Conservative treatment is the first line treatment which consists of splints and orthotic care to reduce the causative factors. Realigning the foot with the aid of an orthotic helps prevent further degeneration and/or reduce symptoms of HAV in any stage of its deformity. Along with orthotic care, patients may require debridement of corns and calluses produced due to extra forces produced on the foot. Orthotics will also help the function of the big toe joint as it allows it to bend in the correct position. Footwear advice is also essential in the conservative care of bunions, HAV, there may be a need to change footwear, so it is able to fit properly and be compliment with orthotics. Surgical correction of bunions, HAV is available, however should only be considered when conservative care has failed to reduce the onset of bunions, HAV. It is only considered if there is a clear sign that it will induce a better quality of life for the patient.
Orthopaedic surgeons use many different surgical procedures to treat bunions. The common goal of these procedures is to realign the joint, relieve pain, and correct deformity. These procedures include repair of the Tendons and Ligaments Around the Big Toe. These tissues may be too tight on one side and too loose on the other, creating an imbalance that causes the big toe to drift toward the others. Often combined with an osteotomy, this procedure shortens the loose tissues and lengthens the tight ones. Removal of the damaged joint surfaces, followed by the insertion of screws, wires, or plates to hold the surfaces together until it heals. Used for patients with severe bunions, severe arthritis, and when other procedures have failed. Removal of the bump on the toe joint, used only for an enlargement of the bone with no drifting of the big toe. This procedure is seldom used because it rarely corrects the cause of the bunion. Removal of the damaged portion of the joint, used mainly for patients who are older, have had previous bunion surgery, or have severe arthritis. This creates a flexible "scar" joint. The surgical cutting and realignment of the joint. Your orthopaedic surgeon will choose the procedure best suited to your condition.
