Multifunctional humeral intramedullary nail is an orthopedic implant used for the treatment of humeral fractures, mainly composed of a main nail, multiloc locking screw, locking screw, and end cap.
Introduction
Surgical treatment is required for displaced or unstable fractures of the proximal humerus, which are more common in the elderly population. Humeral nail surgery is a widely used treatment option.
Symptoms and treatment methods of proximal humeral fracture
Proximal humeral fracture refers to a fracture involving the upper part of the humerus, such as the surgical neck of the humerus, anatomical neck of the humerus, head of the humerus, large and small nodules of the humerus, and other bone structures. Patients usually experience symptoms such as shoulder swelling, shoulder pain, limited mobility, and bone fricatives. Classify according to the position and degree of displacement. Non displacement fractures can usually be treated conservatively, such as sling fixation and early exercise. However, displaced fractures may require surgical intervention, such as the implantation of humeral screws, to restore shoulder function and prevent complications.
Surgical treatment of humeral nail
The humeral interlocking nail surgery involves inserting an intramedullary nail through the proximal humerus to stabilize the fracture. The main nail is inserted through a small incision near the shoulder joint and guided into the medullary canal using an endoscope. After the nail is in place, insert the screw through the nail into the humeral head to fix the fracture.
Indications for humeral nails
The multifunctional humeral intramedullary nail is suitable for humeral shaft fractures, fractures extending to the shaft, fractures accompanied by shortening and rotation of the fracture segment, and fractures accompanied by shortening and rotation of the fracture segment. In these cases, multifunctional humeral intramedullary nails can provide effective internal fixation and support, helping to restore the normal shape and function of the humerus.
Surgical technique of humeral nail
The humeral nail surgery can be performed using either anterograde or retrograde methods. The anterograde approach involves inserting the nail through the proximal humerus, while the retrograde approach involves inserting the nail from the distal humerus. The choice of approach depends on the location of the fracture and the preference of the surgeon.
Advantages of humeral nail
1. It can provide stable internal fixation, which helps promote fracture healing and recovery.
2. Internal fixation can reduce the movement of the fracture site, which helps alleviate pain and promote functional recovery.
3. Multi functional design can adapt to different types and positions of humeral fractures, improving surgical flexibility and success rate.
4. Compression and stability of the fracture site can be achieved through the adjustment and fixation of screws, which helps to restore the normal shape and function of the humerus.
The results of humeral nail surgery
Humeral nail surgery has been proven to be one of the effective options for treating proximal humeral fractures, with high fracture healing rate and good function. However, careful patient selection and sophisticated surgical techniques can minimize the occurrence of complications such as screw incision, non healing, and infection.
Conclusion
Proximal humeral fracture will have a significant impact on the incidence rate and mortality of patients, especially in the elderly. Humeral nail surgery can effectively restore shoulder function and prevent complications, and is a widely used intramedullary nail implantation technique.
