Can a femoral head necrosis occur after 3 months of femoral neck fracture?

1) Healing of femoral neck fracture Femoral neck fracture healing is slow, taking an average of 5 to 6 months, therefore, the diagnosis of healing should not be less than 5 years; The factors affecting fracture healing are related to age, physical condition, fracture location, fracture type, fracture and displacement degree, reduction quality, and internal fixation strength. According to relevant statistics, the nonunion rate of fractures is relatively high, with an average of about 15.

2) The problem of avascular necrosis of the femoral head.

Avascular necrosis of the femoral head remains a serious and unresolved problem. According to the literature, the necrosis rate is generally 20 35. The earliest time of femoral head necrosis is 2 to 3 months after injury, and the latest can be 5 years, and it is generally believed that the postoperative observation time should not be less than two years.

3) Functional recovery of femoral neck fractures.

Functional recovery from femoral neck fractures is not as good as for other fractures. Generally speaking, only about half (50) of patients are able to achieve satisfactory functional recovery, and they can walk easily, painlessly, and squat freely. About 15% of patients have nonunion fractures.

About 20 to 35 percent of patients have necrosis of the femoral head. There are also some patients who develop traumatic arthritis of the hip after the injury.

Therefore, it is necessary to avoid weight bearing for at least two years in order to better promote early **.

You fall, and there is generally no necrosis of the femoral head....If it is a pathological fracture, such as a fracture caused by tuberculosis, there is a high risk of necrosis of the femoral head, ...... occurIt stands to reason that you should be fine in three months, and you don't need a re-examination.

Femoral head necrosis is usually possible within 5 years after a femoral neck fracture**. The probability of occurrence is only statistically significant, there is no specific data, and it can only be said that it has a certain proportional relationship with the high age, the severity of the injury, the location of the fracture line and the ** plan chosen. The older the age, the more prone to necrosis, the location of the fracture line will also affect the possibility of femoral head necrosis, young people, middle-aged people and the elderly femoral neck fracture surgical options are also different, and the selection of inappropriate surgical plans will also lead to an increased possibility of femoral head necrosis.

In general, after a femoral neck fracture**, it is necessary to have regular reexaminations within 5 years so that signs of femoral head necrosis can be detected in time and can be treated in time, and in the case of children or young adults, the observation time should be longer.

Avascular necrosis of the femoral head after a femoral neck fracture is typically typical because it often occurs continuously during the recovery period from trauma.

Deep tenderness, localized deep tenderness at the midpoint of the groin and posterior piriformis muscle, and tenderness at the adductor insertion due to adductor muscle tension

Hip dysfunction:"4"positive word test, positive Thomas's sign, abduction, external rotation, internal rotation, and significantly limited flexion activity

Limb shortening due to collapse of the femoral head, positive Ellis's sign, positive Tedrenberg's test;

Significant disuse amyotrophy;

Longitudinal axis percussion pain of the affected limb is positive when intramedullary pressure is high, the pressure in the joint cavity is high, or when the repair of dead bone resorption reaches the articular surface.

It is recommended to pay attention to the maintenance of the femoral head in daily life, and avoid weight bearing, trauma, hormones, alcohol, etc.

Because the blood vessels of the femoral head are all around the femoral neck, they are prone to necrosis.

After the fracture of the femoral neck, the blood vessels will be destroyed, and the blood vessels are all around the femoral neck, resulting in blood restriction**, resulting in ischemia of the femoral head and necrosis of the femoral head.

The femoral head supports our upper body, due to the long-term pressure of the upper body, although the fracture is recovered, it will also cause necrosis of the femoral head for a long time.

Because the bone is injured after a fracture, it is more susceptible to injury, and the bone is easy to die after being injured.

Because his injury to the femoral head is relatively close. So it will be a big deal of damage. Therefore, you should pay attention to it in your daily life.

Femoral neck fractures are particularly prone to necrosis of the femoral head, the main reason is that after you are injured in the middle of this bone, you will find that its recovery is very slow, in this case, a special necrosis of the bone will be formed, then it is a very serious phenomenon.
