How To Spot Bunions
OverviewThe prominent bone at the side of the big toe rubs against the shoe and the skin becomes reddened. Often a sac of fluid called a bursa may develop in the tissue overlying the prominent bone. This swelling, consisting of inflamed soft tissues and underlying prominent bone is what we call a ?bunion?. If left untreated, they can be very painful. CausesBunions form when the normal balance of forces that is exerted on the joints and tendons of the foot becomes disrupted. This disruption can lead to instability in the joint and cause the deformity. Bunions are brought about by years of abnormal motion and pressure over the MTP joint. They are, therefore, a symptom of faulty foot development and are usually caused by the way we walk and our inherited foot type or our shoes. SymptomsThe initial symptom may be pain at the joint prominence when wearing certain shoes. The joint capsule may be tender at any stage. Later symptoms may include a painful, warm, red, cystic, movable, fluctuant swelling located medially (adventitial bursitis) and swellings and mild inflammation affecting the entire joint (osteoarthritic synovitis), which is more circumferential. With hallux limitus or rigidus, there is restriction of passive joint motion, tenderness at the dorsolateral aspect of the joint, and increased dorsiflexion of the distal phalanx. DiagnosisOrthopaedic surgeons diagnose bunions on the basis of physical examination and weight bearing x-rays. Two angles are assessed, the intermetatarsal angle, that is between the first and second metatarsals (the bones that lead up to the base of the toes). If this angle exceeds 9? (the angle found in the healthy foot) it is abnormal and referred to as metatarsus primus varus. the hallux valgus angle, that is, the angle of the big toe as it drifts toward the small toe. An angle that exceeds 15? is considered to be a sign of pathology. Non Surgical TreatmentApply a commercial bunion pad around the bony prominence, use only non-medicated pads. Wear shoes with a wide and deep toe box. You should be able to "dimple" the leather over your bunion. Avoid all high heeled shoes. If your bunion becomes painful red, and swollen try elevating your foot and applying ice for about 20 minuets every hour. If symptoms persist, consult your podiatrist or physician. Surgical TreatmentThe primary goal of bunion surgery is to relieve the pain associated with the deformity. This is accomplished by correcting the underlying abnormal metatarsal position by realigning it toward the second toe. Removing excessive bone formation on the bunion "bump", releasing the soft tissue tightness which is pulling the big toe towards the second toe. Tightening the soft tissues which are overly stretched on the bump side of the joint. Re-establish the correct alignment of the cartilage surfaces. Move the sesamoid bones into correct alignment. Realign the great toe. Bunion surgery procedures are based on many factors, including health, age and lifestyle of the patient. However, a critical factor in procedure choice is the grading of the bunion deformity. PreventionTo help prevent bunions be sure your shoes don't cramp or irritate your toes. Choose shoes with a wide toe box - there should be space between the tip of your longest toe and the end of the shoe. Your shoes should conform to the shape of your feet without squeezing or pressing any part of your foot. Avoid pointy-toed shoes.
