"Bones" at the base of the big toesIt appears for various reasons, but in most cases they are the result of deforming osteoarthritis metatarsophalangeal joints and are accompanied by outward deflection of fingers. Most often the disease occurs in women, and the reason for this becomes uncomfortable wearing dress shoes with a narrow nose and high heels. However, this is not all of the factors that can serve as an impetus to the development of osteoarthritis of the thumb.
Causes of osteoarthritis of the thumb as, indeed, andosteoarthritis of other joints of the foot in common with the etiology of degenerative diseases in general. However, in the first place in the list of pathogens is a joint microtrauma.
- Wearing narrow shoes compression foot in the metatarsophalangeal joints.
- Wearing shoes with heels and redistribute the load on the various departments of the foot, overloading the metatarsophalangeal joint arthrosis and provoking the large and often the second toe.
- Flat feet, and often a longitudinal than the cross violates the biomechanics of the foot.
- Continuous vertical load on the foot, such as walking long distances, work, assuming a standing position, which form a flat foot.
- Chronic microtrauma of the joints as a result of professional activity. For example, in athletes and ballet dancers osteoarthritis of the big toe is quite common.
- Acute trauma to the joint.
- Hypothermia feet.
All these factors suggestdirect destruction of articular cartilage in combination with inflammation and blood circulation, leading to degeneration and subsequent degeneration of the cartilage. As a result of lower depreciation stability of the articular cartilage and increase the load on the bones that form the joint, osteophytes are formed, which distort the joint and contribute to the further deflection thumb outward of the foot. The subsequent destruction of the bone accompanied by the formation of cystic cavities, arthritis development and further disease progression.
Radiological deforming osteoarthritismetatarsophalangeal joint of the foot appears narrowing of joint space, the formation of marginal growths of bone, joint degeneration. Bony growths are formed mainly on the back and the plantar side of the outer joint department. At an inner portion, they appear only when the position of the bones forming the joint is normal.
Osteoarthritis - a chronic disease, and sharpeningaccompanied by joint inflammation. For this stage of disease are typical manifestations of pain, redness and swelling in the joint. Movement in the metatarsophalangeal articulation become painful and limited, which leads to lameness. In the period of remission there is increased joint fatigue, pain after excessive stress, bone joint deformation.
In its development, the metatarsophalangeal osteoarthritis goes through several stages.
stage I - At this stage of the disease is manifested fatigue, recurrent pain in the joint, associated with the load pressure, but these symptoms disappear after a rest.
stage II - General and osteoarthritis arthritis metatarsophalangealjoint in particular is characterized by more severe pain, only slightly sagging during the holidays. The joint is constrained, deformed toe deviates outwards and downwards.
stage III - The disease leads to severe strainjoint and constant pain. This forces to abandon the model of shoes and limit physical activity. Trying to unload the affected joint, patients with walking body weight is transferred to the outer side of the foot, resulting in the plantar surface of the base 4 and pin 5 painful blisters appear.
Osteoarthritis of the first toe severely limits the physical capabilities of the patient, but does not lead to disability.
