Patellar tendon rupture

Introduction to fracture The iliac crest is usually avulsed at the lower edge of the humerus. It can also be seen that the distal tibial tuberosity is avulsed. Due to the contraction of the quadriceps, the tibia can be retracted 3-6 cm with the quadriceps tendon. Therefore, for the fracture, early repair should be emphasized. In the late stage, reconstruction surgery was often performed due to contracture and scarring after loss of tension. basic knowledge The proportion of illness: 0.001% Susceptible people: no specific population Mode of infection: non-infectious Complications: Arthritis

Cause of sputum fracture

(1) Causes of the disease

Because the injury of the knee extension device is usually caused by the sudden flexion of the knee joint and the sudden and severe contraction of the quadriceps muscle, and at this time, the humerus is the fulcrum of the femoral condyle of the entire knee extension device, and therefore, the injury of the knee extension device is There are many fractures of the tibia, and the fracture of the quadriceps tendon and tendon is relatively rare.

(two) pathogenesis

A typical trauma mechanism is a sudden strong protective contraction of the quadriceps muscle during an unprepared knee flexion resulting in degenerative or weak tendon rupture.

break prevention

Preventive work begins with the details of life. Pay attention to calmness and avoid emotional conflicts leading to the disease. Secondly, early detection, early diagnosis and early treatment are also important for indirect prevention of this disease.

Fracture complications Complications

The symptoms of this disease are often not serious in the early stage. The rest or general painkillers can be relieved. The lesions continue to develop under the hidden state until the development of patellofemoral arthritis. In severe cases, the knee flexion and extension activities are limited and cannot stand on one leg. . When tibiofemoral arthritis has developed in the late stage, the cartilage and subchondral bone in the lesion area have been significantly damaged, and the cartilage has no ability to regenerate. In addition, the disease is also easy to merge with meniscus injury and traumatic arthritis. Secondly, once the disease is diagnosed, it is necessary to immediately perform ligament repair and fix the joint avoidance activity. After 8 weeks of fixation, the plaster can be removed and the rehabilitation training is gradually strengthened to promote the recovery of the disease.

Symptoms of sputum fracture common symptoms knee extension trauma wound nodules

Most occur in people over the age of 40. The location of the fracture is mostly in the lower humerus and the tibial tuberosity. After trauma, the patient has a typical knee extension, tenderness at the fracture site, hemorrhage, discontinuous emptiness, and humerus up.

fracture inspection

No relevant laboratory tests. X-ray films (lateral position) can show the rupture of the iliac crest and the avulsion of the tibial tuberosity.

Diagnostic identification of sputum fracture

diagnosis

Trauma history, clinical manifestations, typical knee extension and X-ray examination can be diagnosed.

Differential diagnosis

The disease is mainly differentiated from the fracture of the tibia. The fracture of the tibia is often accompanied by a history of trauma. Generally, the violent compression of the gastrocnemius muscle and the quadriceps muscle cause the muscles to contract and break the humerus. After the fracture, there is also the inability to stand upright, pain, and walking obstacles. Therefore, the clinical manifestations of the two are extremely similar, and can be differentially diagnosed by the plane of the knee joint and CT examination.
