flaccid metatarsalgia
Introduction
Introduction to Relaxation Pain Plantar pain is the pain of the forefoot humeral head or humeral shaft. According to its etiology, it can be divided into relaxation pain and pressure pain. basic knowledge The proportion of illness: 0.03--0.05% Susceptible people: no specific population Mode of infection: non-infectious complication:
Cause
Cause of relaxation pain
(1) Causes of the disease
Because the congenital first metatarsal is too short, it can not be effectively weight-bearing, but the second or third metatarsal replacement requires disease.
(two) pathogenesis
More often occurs on the basis of congenital first metatarsal deformity, such as the first metatarsal is too short, varus or abnormal activity, because the first metatarsal can not be effectively weight-bearing, but need the second or third metatarsal replacement, under normal circumstances, bone The contraction of the iliac crest makes the humeral heads close to each other. If the weight is increased, the long-distance walking, strenuous exercise, and the weakness of the foot after the disease, the interosseous muscle atrophy is weak, the stability of the humeral head is reduced, and the transverse arch is collapsed. Pain occurs when the transverse ligament is loose.
Prevention
Relaxation pain relief
Congenital diseases are temporarily preventable. Advocate eugenics and prenatal care.
Complication
Relaxation pain complications Complication
Can be clawed toe.
Symptom
Relaxation pain symptoms common symptoms foot swelling tenderness
The pain is located on the transverse ligament of the humeral head. It has persistent burning pain and is aggravated when walking. It can affect the calf. There are tenderness on the temporal and dorsal sides of the humeral head. There are sputum on the face, wide forefoot and atrophy of the interosseous muscle. Presenting a claw toe.
Examine
Examination of loose pain
X-ray plain film can be seen, the first and second tibia and two wedge-shaped bone gaps are widened; the second and third humerus are thick and fat, and the density is increased; the first metatarsal shortening, varus and other deformities, generally do not need CT And MRI examination.
Diagnosis
Diagnosis and diagnosis of relaxation pain
There is a typical clinical manifestation, X-ray shows that the first, second tibia and two wedge-shaped bone gap widening can be diagnosed.
Pain toe joint pain is a pain involving the metatarsophalangeal joint. It is a common symptom, almost all due to subsurface dislocation caused by abnormal joint surface and impact of joint capsule and synovial membrane, eventually leading to destruction of articular cartilage (degenerative joint disease) .
If the joint pain does not have obvious fever and swelling, inflammatory joint disease can generally be ruled out, but it is beneficial to check according to rheumatism. Joint pain without burning sensation, no numbness or tingling, can be distinguished from neuroma or neuralgia of the interphalangeal nerve.
When the joint is palpated and the joint is active, tenderness usually occurs on the dorsal side and the sole of the joint, and the symptoms of neuralgia are often limited to the sole of the foot.
