What Are the Causes of Pain with Hip Flexion?

Femoral neck fractures are one of the common fractures in middle-aged and elderly people. Almost all middle-aged and elderly people's femoral neck fractures are caused by indirect violence, mainly external rotation violence, such as a flat fall, sudden lower limb torsion, etc. can cause fractures. Generally, it is due to slippery roads, uneven roads, and lower limb twisting, varus, or eversion when the upper and lower steps are injured. There are also internal factors, such as osteoporosis, which are mainly due to frailty, poor neuromuscular regulation, inflexible joints, and lack of defense responses to external injuries. Because the osteoporosis of the femoral neck of the elderly is fragile and bears a lot of pressure, only a small rotational external force will cause a fracture.

Hip pain in the elderly

Because the elderly are susceptible to osteoporosis, which makes the femoral neck of the elderly more vulnerable, sometimes a slight fall can cause a fracture. Coupled with the poor blood flow of the femoral neck in the elderly, this will lead to the clinical symptoms of hip pain after the fracture of the elderly, the wound does not love healing or ischemic necrosis of the femoral head.

Femoral neck fractures are one of the common fractures in middle-aged and elderly people. Almost all middle-aged and elderly people's femoral neck fractures are caused by indirect violence, mainly external rotation violence, such as a flat fall, sudden lower limb torsion, etc. can cause fractures. Generally, it is due to slippery roads, uneven roads, and lower limb twisting, varus, or eversion when the upper and lower steps are injured. There are also internal factors, such as osteoporosis, which are mainly due to frailty, poor neuromuscular regulation, inflexible joints, and lack of defense responses to external injuries. Because the osteoporosis of the femoral neck of the elderly is fragile and bears a lot of pressure, only a small rotational external force will cause a fracture.

Hip pain in the elderly after trauma and inability to move should be considered a hip fracture, including a femoral neck fracture. A common special manifestation is pain and tenderness. Hip pain after a fall injury, tenderness in front of the hip, and throbbing pain in the soles of the feet, called indirect throbbing pain, are important signs of fracture. The elderly suffer from hip pain after falling and are afraid to stand and walk, most likely due to a femoral neck fracture. In addition to the spontaneous pain of the hip, the pain is more obvious when the affected limb is moved, but sometimes the fracture has only cracks without displacement, and the patient's pain is not obvious. He can even stand and walk.

Hip fractures often occur in elderly people after a fall. After the injury, the affected side usually has pain in the hip. Sometimes, it may be described as knee pain (due to the obturator nerve reflex). It is impossible to stand. Mild shortening that causes the lower limbs to be unequal in length is a very diagnostic feature. Squeezing the front of the affected hip can cause pain during the examination, and tapping the heel can make the pain worse. X-rays should be taken immediately to confirm the diagnosis of the fracture, and at the same time determine its type. Generally speaking, as long as the hip fracture of the elderly is treated in time and X-ray examination is performed, accurate diagnosis is not difficult. However, special attention should be paid to some non-displaced fractures that can still walk after the injury. At this time, the fracture line can not see the fracture line, which is likely to cause missed diagnosis, and patients often continue to walk, eventually leading to complete misalignment of the fracture. Therefore, for some elderly patients with falls and no obvious symptoms, further CT examinations can be performed, or patients can stay in bed with special T-shaped wooden shoes for 2-3 weeks before X-ray examination.

Differential diagnosis of hip pain in the elderly:

1. Swelling and tenderness of the lateral hip: Swelling and tenderness of the lateral hip is one of the clinical diagnosis basis for intertrochanteric fractures. Femoral intertrochanteric fractures mostly occur at 66 to 76 years of age. The incidence is three times higher in women than in men. Griffin and Boyd's study of 300 cases of femoral intertrochanteric fractures shows that the mortality rate of patients within 3 months after injury is 16.7%, which is about twice the mortality rate of patients with femoral neck fractures. The reason for such a high mortality rate is that the patient is older; the trauma that caused the fracture is heavier; the blood loss after the fracture is large; the treatment operation is relatively large. It can be seen that the intertrochanteric fracture is a more serious fracture.

2. Hip pain: It is commonly known as patellofemoral pain. In medicine, we call it hip pain, referred to as hip pain, which is expressed as uncomfortable pain in or around the hip joint. There are many causes of hip pain, and there are major causes for different age groups.

3. Hip discomfort: Swelling caused by acetabular dysplasia will initially be located in the knee joint, and then mainly in the hip, thigh root, and groin areas. The initial manifestation is hip soreness and discomfort, which increases after standing or walking for a long time, and generally improves slightly after rest. Most patients don't think it's due to fatigue or sprain.

Elderly people should pay special attention to protecting their femoral head parts. When exercising or doing housework, pay attention not to hit the hips or use the hips hard. Do not lift or lift heavy objects, and try to avoid accidental injuries to reduce the chance of femoral neck fractures. If the elderly have suffered trauma, such as falling or bumping, they must immediately stop the movement of the affected limb, and go to the hospital to take X-ray examinations in time to clear the diagnosis, so as not to lose the opportunity of early treatment.
