Femoral neck fracture becomes shorter after surgery, and it is difficult to move for 2 years

Reduction and prevention of necrosis:

Wash with tung bark soup. Paste the ointment. Take 2-3 courses of Bone Strengthening Pill.

First of all, understand what causes shortening? Did it collapse due to necrosis?

If it's a physical principle, of course. See you. Trim your shoes. It's impossible to cut a good leg shorter. Hehe. But you can have a short leg pad high balance.

One and a half years after the femoral neck fracture, the affected area is uncomfortable and may be necrosis. The average healing time for femoral neck fractures is about six months, and when the criteria for healing are met, patients can begin normal activities. However, specific complications such as avascular necrosis of the femoral head thigh bonecrosis, which is one of the most serious and common complications, are most likely to occur 6 to 1 1/2 months after surgery for a femoral neck fracture.

Necrosis of the femoral head is one of the least desirable complications for patients with femoral neck fractures, but it does have a high incidence and is uncomfortable for everyone. Therefore, in order to achieve early prevention and early development, it is necessary to understand the causes of femoral head necrosis secondary to femoral neck fracture and related high-risk factors, so as to achieve the purpose of early prevention and early prevention.

<> What are the causes of high incidence of necrosis of the femoral neck after femoral head surgery? Blood vessels are formed earlier than bones, so they can supply blood to hard bones. By the time a patient has a fracture, the blood vessels in the femoral head may have been damaged, and the femoral head may develop avascular necrosis due to a lack of nutrients in the blood vessels.

Normally, a bone has a large number of blood vessels**it, and when the blood vessels rupture, it can also form a collateral circulation to **no blood** area, and the collateral circulation usually takes about a week to form. This means that many times, when we ligate arterioles, we do not cause limb ischemia and necrosis.

There are many methods, but the most common is three-nail fixation. The patient was afraid of necrosis, so it is estimated that a three-nail internal fixation was done. Joint Replacement:

Depending on the problem, the patient does not have a joint replacement, so it will not be discussed for the time being. What is the cause of discomfort at the site of infection after 1 and a half years of internal fixation? Necrosis of the femoral head:

The early diagnosis of necrosis of the femoral head is MRI, although there is internal fixation, but the current internal fixation is titanium alloy, and low MRI can be done. Therefore, MRI is recommended to determine the presence of necrosis. Of course, don't worry too much, the surrounding soft tissue damage or ** bad will also appear in the discomfort of the affected area.

The main reason for the occurrence of non-union.

1. Age Most scholars believe that too high age is a factor affecting fracture healing, and in foreign countries, the nonunion rate is 32% and 41% at the age of 75; 18% under the age of 75. As a result, the nonunion rate in patients over 75 years of age has increased significantly. 2. Degree of fracture displacement The more serious the fracture displacement, the more difficult it is to heal, which is a recognized law and the most important factor affecting fracture healing.

3. Fracture site At present, most people believe that in addition to femoral neck basal fractures, intracapsular fractures alone have a high non-union rate of high subcephalic fractures. 4. Comminuted fracture site Comminuted fractures mostly occur on the posterior side of the femoral neck, and are difficult to find on the X-ray before reduction. In the case of garden fractures, the nonunion rate is 5% for mild comminutions, moderate for those with moderate comminutions, and 75% for severe comminuters.

The impact of trailing edge crushing on the solidity of the internal fixation is also a factor. 5. The inclination of the fracture line Regarding the clinical significance of the measurement of Pauwell and Linton angles, the inclination of the fracture line is currently used as a separate factor to determine fracture healing, which is insufficient. The inclination of the fracture line had no significant effect on fracture healing.

6. Poor fracture reduction Poor reduction of femoral neck fracture will hinder head revascularization, reduce the contact between the distal and proximal end of the fracture and cause mechanical instability after fixation. 7. The fixation is unreasonable. 8. Premature and unreasonable weight bearing.

Femoral neck fractures are relatively common fractures, and there are two methods:

1. As long as there is a chance of healing, the method of internal fixation is adopted, that is, the internal fixation instruments (hollow nails, power hips, goosehead nails, etc.) are used to connect the two ends of the fracture to allow the fracture to heal, and there is no need for plaster external fixation after internal fixation. It is suitable for patients who are relatively young, have good bone conditions, and the fracture is not particularly serious.

2. Considering that there is no healing or the chance of healing is very small, and the femoral head has irreversible necrosis, these situations are all replaced by the femoral head or total hip placement.

From the situation you described, it is correct for the patient to do internal fixation, but this does not mean that it will be healed, it is related to the specific situation of the fracture, the patient's general condition, and the internal fixation, and no one can give you a ticket.

If the internal fixation does not heal due to internal fixation, the internal fixation can be redone, and whether it heals or not is the same as in the case of the first surgery. If necrosis of the femoral head has already occurred, the only option is joint replacement, and the patient's condition only requires the replacement of the femoral head. It should be noted that the prosthesis of femoral head replacement has a limited service life, which is usually said to be that the imported joint can be used for more than 10 years, and then it will have to be revised, and if the normal life expectancy of 80 years old is calculated, at least 3 or more joint replacement surgeries will be required.

Hope it helps.
