patella fracture
Introduction
Introduction The tibia is an important part of the knee joint and the largest sesamoid in the human body. The humeral fissure is medically known as a crack fracture and is one of the types of humeral fractures. In the knee extension activity, the tibia can increase the strength of the quadriceps by about 30% by leveraging, especially when the last 10° to 15° of the knee joint is extended, the effect of the tibia is more important. Improper treatment after a fracture of the humerus will seriously affect the activity of the knee joint and even cause lifelong disability. Because the patella can cause permanent knee function limitation, the knee extension strength is weakened and the quadriceps atrophy can be caused. Therefore, the humerus should be preserved as much as possible after the fracture of the tibia. The tibiofemoral joint is formed in the anterior and posterior aspect of the tibia and femur. The fracture of the humerus should be restored as much as possible to reduce the occurrence of traumatic patellofemoral arthritis.
Cause
Cause
Usually caused by direct blows, slight impacts and falls. Clinically, crack fractures without obvious displacement are the most common. If there is no displacement after the fracture of the tibia, it is fixed by plaster (usually 3-4 weeks) to achieve bone healing, generally not causing traumatic arthritis, but if The fracture is poorly aligned, and the friction during the joint movement may cause traumatic arthritis in a few years.

CT examination of bones and joints of limbs and joints
First, physical examination
Taking a medical history gives us a first impression and revelation, and also guides us to a concept of the nature of the disease.
Second, laboratory inspection
Laboratory examinations must be summarized and analyzed based on objective data learned from medical history and physical examination, from which several diagnostic possibilities may be proposed, and further consideration should be given to those examinations to confirm the diagnosis.
Such as: obvious history of trauma, pain in the affected limb, limited activity. The sacral line can determine the location of the fracture and the displacement.
Diagnosis
Differential diagnosis
The humerus is bruised and kicked. The fractures are mostly comminuted. The aponeurosis and joint capsules on both sides of the aponeurosis and iliac crest are well preserved, and they can also be transverse fractures. Indirect violence, mostly due to the quadriceps contraction, the resulting traction injury, such as sudden slip, knee flexion, quadriceps contraction, tendon bone upward, patellar ligament fixation lower part of the humerus, And caused a fracture of the tibia. Indirect violence is a transverse fracture, with large displacement, and severe tearing of the anterior fascia and bilateral dilatation.
