The Proximal Humerus Fracture Surgery Explained
The Proximal Humerus Fracture Surgery Explained A proximal humerus fracture involves a break in the upper part of the arm bone, near the shoulder joint. This type of injury is common, especially among older adults with osteoporosis, as well as in sports accidents or falls. While many minor fractures heal with conservative treatment such as immobilization, more complex or displaced fractures often require surgical intervention to restore function and prevent long-term disability.
Surgical treatment options for proximal humerus fractures vary depending on the fracture’s pattern, displacement, patient age, activity level, and overall health. The primary goal of surgery is to realign the fractured bone fragments and stabilize them to allow for proper healing and restore shoulder mobility. The Proximal Humerus Fracture Surgery Explained
One common surgical technique is open reduction and internal fixation (ORIF). In this procedure, the surgeon makes an incision over the shoulder to access the fractured bone. Using specialized tools, the surgeon realigns the bone fragments—this process is called reduction—and then secures them with hardware such as plates and screws. The plates are contoured to fit the anatomy of the proximal humerus, and the screws hold the fragments in place as the bone heals. This method is often preferred for fractures where the bone fragments are displaced but still have good blood supply. The Proximal Humerus Fracture Surgery Explained
In cases where the fracture is severely comminuted (broken into many pieces) or if the bone quality is poor, especially in elderly patients with osteoporosis, a shoulder replacement may be considered. This involves removing the damaged head of the humerus and replacing it with a prosthetic component. This procedure, known as shoulder arthroplasty, provides immediate stability and pain relief, often resulting in better functional outcomes for certain patients.

Minimally invasive techniques, such as percutaneous pinning, are also employed in some cases. This involves inserting metal pins through small incisions to hold fracture fragments together. While less invasive, this method is generally suitable for specific fracture types and less complex injuries.
Postoperative care is crucial for successful recovery. Patients typically wear a shoulder immobilizer temporarily to protect the repair. Early passive range-of-motion exercises are initiated to prevent stiffness, followed by gradual strengthening activities. The timeline for returning to normal activities varies, but most patients regain significant shoulder function within several months. The Proximal Humerus Fracture Surgery Explained
Complications from proximal humerus fracture surgery can include infection, nerve or blood vessel injury, hardware failure, or nonunion of the fracture. Therefore, choosing an experienced orthopedic surgeon and adhering to postoperative instructions are key factors in achieving a positive outcome. The Proximal Humerus Fracture Surgery Explained
In summary, proximal humerus fracture surgery aims to restore the anatomy and function of the shoulder. Whether through fixation or replacement, advances in surgical techniques continue to improve recovery times and functional results for patients suffering from these complex injuries.
