Fracture of proximal fibula

Introduction to proximal humerus fracture The humerus is one of the two bones of the calf. It is located at the outer part of the calf, and the outer part of the tibia is slender and divided into one body and two ends. Most fractures often occur in combination with the upper humerus or humeral shaft fracture, but direct external force can cause fracture of the humeral head or neck. The fracture line may be oblique or transverse, and the displacement of the broken end is less common. basic knowledge Sickness ratio: 0.0001% Susceptible people: no special people Mode of infection: non-infectious Complications: common peroneal nerve injury

Causes of proximal humerus fracture

The disease is mainly caused by traumatic factors, mostly caused by direct external force on the outside of the calf. The traumatic violence includes impact and crush injury caused by car accidents, heavy body bruises, and wounds.

Proximal humerus fracture prevention

The disease is caused by traumatic factors. Paying attention to production and life safety is the key to preventing this disease.

Complications of proximal humerus fracture Complications, common peroneal nerve injury

Most of these types of fractures have upper humeral or humeral shaft fractures, which are collectively referred to as proximal humeral fractures. These fractures are difficult to fix because they are close to the knee joint. They are complicated by joint stiffness, skin necrosis, infection and other complications. In some serious cases, such as burst fractures, in addition to bone damage, there are also very serious soft tissue injuries, mostly associated with blood vessels, common peroneal nerve injury, if the treatment is unreasonable, the soft tissue damage is aggravated, the presence of foreign bodies, Increased wound tension, easy to develop skin necrosis and infection.

Symptoms of proximal humerus fractures Common symptoms Calf muscles of the calf muscles... Joint pain, sacral muscle tear, simple fracture, sacral muscle symmetry atrophy... Gastrocnemius muscle strain

The main symptoms of this disease are lateral calf pain, swelling and tenderness, and a history of direct external injury to the outside of the calf. Although the patient can walk without walking, but the weight is painful, the tenderness is in the soft tissue contusion fracture site, but if squeezed in the middle of the calf The humerus, or the pain in the wound site caused by the fixed rotation of the knee, may be a proximal humerus fracture. In addition, when the affected limb is resistant to knee flexion, the biceps femoris attaches to the humeral head, causing pain.

Examination of proximal humerus fracture

The disease has a clear history of trauma, generally according to its medical history and physical examination can be diagnosed, auxiliary examination is mainly X-ray examination, X-ray film can show the specific location of the fracture and the scope of the injury, is conducive to diagnosis, for some special In cases, X-ray examination is not sufficient to clearly determine the condition, CT examination can be used.

Diagnosis and diagnosis of proximal humerus fracture

Diagnosis can be based on medical history, clinical symptoms, and laboratory tests.

For the proximal humeral fracture combined with a tibial fracture, and a burst fracture, it needs to be differentiated from the tibial plateau fracture, especially in the treatment of many different places.

Proximal rupture of the humerus refers to a comminuted fracture caused by strong violence in the proximal part of the humerus. The fracture is "explosive"-like rupture and affects the tibial plateau, accompanied by fractures of the humerus and external malleolus. The fracture injury mechanism is different from the sputum type in the Schatzker classification of the tibial plateau fracture. The fracture of the tibial plateau is mostly the violent impact of the knee joint in the knee joint, the lateral side, the knee joint, the valgus, causing the tibial plateau and the lateral collapse fracture. The main metaphysis involved, the main fractures are oblique and transverse fractures, and the other are associated with collateral ligaments, knee ligament and meniscus injury, while the proximal humeral fractures are mainly caused by direct violence in the upper part of the lower leg, soft tissue The injury is very serious, mostly accompanied by blood vessels, common peroneal nerve injury, both intra-articular fractures and shortening of the length of the tibia. Both treatments require restoration of the articular surface integrity and tibia height of the tibial plateau as much as possible, but the humerus is near. The treatment of the end burst fracture is more difficult than the tibial plateau fracture, and the proximal humeral burst fracture is a high-energy injury, which not only causes severe comminutedness. Fracture, and cause severe local soft tissue injury, severe soft tissue injury is easy to cause complications of internal fixation after incision, but without internal fixation, fracture stability is difficult to maintain, can lead to nonunion or malunion, closed reduction External fixation is only suitable for large fractures without comminution and displacement. For the treatment of burst fractures, limited internal fixation combined with external fixation for the treatment of tibial plateau fractures with severe soft tissue injury, the needle infection rate is 10%. Bone traction can gradually restore the limb force line, reduce the possibility of blood vessel compression, and at the same time facilitate the observation of soft tissue swelling, and can open the fascia decompression at any time to prevent irreversible necrosis of the affected tissue.
