Self-check method and diagnosis of bent finger (kagayumi yubi)

The flexed toe, commonly called hammertoe, mallet toe, or claw toe, together form the disorder flexor digitorum flavum.The following is a list of the most common problems with the

How to do a self-check for bent finger (kagayumi yubi)

Stand with both legs spread apart.

If there are wrinkles at the joints of the second, third and fourth toes, there is a toe deformity called "flexion toe".

Or, if the tips of the toes are white, there is too much pressure on the tips of the toes, resulting in impaired blood flow. This is also a toe deformity called "flexion toe.

What is a hideously bent finger?

Stand with both legs spread apart.

We will put our weight on our feet.When the joints crease only when weight is placed on the foot, "hideous flexor toe"It is called "bending. This is evidence that when you walk, a load of 1.5 to 2 times your body weight is applied to one leg, and you are bending at that time.

How to put weight on the foot

First, in pairs, the standing person folds his or her hands in front of the body.

Open your foot a fistful.

The seated person lightly grasps the wrist of the standing person.

The seated person holds both wrists of the standing person and puts his or her weight directly under them. Check the state of the toes at that time.

What is wrong with a bent finger (kagayubi)?

It is common to get calluses on the toes when you have a bent toe (kagayubi). What else is not good? The 2nd, 3rd, and 4th toes keep the foot from tilting forward.It acts like a "stopper."The more you bend over, the more likely you are to trip and fall. Therefore, if the flexion finger becomes severe, the forward stopper is lost, causing the patient to trip and fall easily.

 

Also, because the center of gravity shifts backward overall,Bent toes → heel center of gravity → backward/forward pelvic tilt (pelvic deformity) → hunchback/warped back (spine deformity) → rolled/warped shoulders→directional marker or indicatorStraight neck (deformation of neck bones) → mouth breathing / low tongue (breathing problems) → misaligned jaw joints / bite and teethand this process leads to a variety of discomforts (see symptom-specific articles for more information).

Bending fingers → numbness of fingertips, falls, pinching, cold, ingrown toenails, Morton's disease
Heel center of gravity → Achilles tendon rupture, swollen feet, cramps in the calves
Anterior/posterior pelvic tilt → swelling, cold, menstrual irregularity, infertility, sciatic nerve pain
Distortion of the spine → hernia, stenosis, scoliosis, lumbago, back pain
Curly shoulder/ankle shoulder → stiff shoulder, frozen shoulder, rotator cuff tear, etc.
Deformation of neck bones → cervical herniation, stiff neck, mouth breathing, low tongue, sleep apnea syndrome
Distortion of facial muscles → TMJ disorder, bite and teeth misalignment

Properly restoring the shape of the bent toe is necessary to keep the entire body straight, not just the feet.It is.

Professional Evaluation and Diagnosis of Crouching Fingers

The diagnosis of flexion toe (kagayubi) can be based on the patient's symptoms and examination results to diagnose metatarsophalangeal joint deformity, or if infection or arthritis is suspected, testing should be performed.

Diagnosis of Crouching Finger

Although flexion toe deformity can be determined by appearance, diagnosis involves examining the course of symptoms and examining the foot. Examinations include reproducing pain symptoms by moving the foot and examining the toe for contractures.Most of the time they are not taken seriously at the hospital.Think of it as.

Hospitals can diagnose extreme deformities, but most often overlook "mild flexion fingers" or "hideous flexion fingers," judging that there will be no particular problem.There is no recognition that bending fingers affect the whole body, and the guidelines themselves have not been developed.This may be a problem.
