ORIF for Humerus Fractures: Techniques and Benefits

Fractures of the humerus, or upper arm bone, can be debilitating injuries that require surgical intervention for proper healing. One common surgical technique used for humerus fractures is open reduction and internal fixation (ORIF). This procedure involves making an incision to realign the fractured bone fragments and then securing them in place with screws, plates, or rods. ORIF for humerus fractures has several techniques and benefits that make it a preferred treatment option for many patients. In this article, we will explore these techniques and benefits in detail.

1. Indications for ORIF

Before discussing the techniques and benefits of ORIF for humerus fractures, it is important to understand the indications for this procedure. ORIF is typically recommended for fractures that meet certain criteria:

  • Displaced fractures: When the bone fragments are significantly out of alignment, ORIF is necessary to restore proper anatomical alignment.
  • Articular fractures: Fractures that involve the joint surface of the humerus may require ORIF to prevent long-term joint dysfunction.
  • Open fractures: If the fracture has broken through the skin, ORIF is often performed to reduce the risk of infection and promote proper healing.
  • Pathological fractures: Fractures caused by underlying bone diseases, such as cancer, may require ORIF to stabilize the bone and alleviate pain.

These are just a few examples of the indications for ORIF in humerus fractures. The decision to perform this procedure is made on a case-by-case basis, taking into consideration the specific characteristics of the fracture and the patient’s overall health.

2. Surgical Techniques

ORIF for humerus fractures can be performed using various surgical techniques, depending on the location and severity of the fracture. The following are some commonly used techniques:

2.1 Plate and Screw Fixation

This technique involves using metal plates and screws to stabilize the fractured bone fragments. The surgeon makes an incision over the fracture site, aligns the bone fragments, and then secures them in place using a plate and screws. This method provides excellent stability and allows for early mobilization of the arm.

2.2 Intramedullary Rod Fixation

In this technique, a metal rod is inserted into the medullary canal of the humerus to stabilize the fracture. The rod is typically inserted through a small incision near the shoulder or elbow joint. This method is particularly useful for fractures that are located in the middle of the humerus shaft.

2.3 External Fixation

External fixation involves the use of pins or screws that are inserted into the bone fragments and connected to an external frame. This technique is often used for complex fractures or when there is significant soft tissue damage. It allows for early mobilization and can be adjusted as the fracture heals.

These are just a few examples of the surgical techniques used in ORIF for humerus fractures. The choice of technique depends on various factors, including the location and complexity of the fracture, the surgeon’s expertise, and the patient’s individual circumstances.

3. Benefits of ORIF

ORIF for humerus fractures offers several benefits compared to non-surgical treatment options. Some of the key benefits include:

3.1 Improved Alignment and Stability

By realigning the fractured bone fragments and securing them in place, ORIF provides better anatomical alignment and stability. This promotes proper healing and reduces the risk of long-term complications, such as malunion or nonunion.

3.2 Early Mobilization

ORIF allows for early mobilization of the arm, which is crucial for maintaining joint function and preventing stiffness. Non-surgical treatments, such as casting or bracing, often require prolonged immobilization, leading to muscle atrophy and joint stiffness.

3.3 Reduced Pain and Improved Function

Properly aligned and stabilized fractures result in reduced pain and improved function. ORIF allows patients to regain their pre-injury level of activity and return to their daily routines more quickly.

3.4 Lower Risk of Infection

ORIF reduces the risk of infection compared to non-surgical treatments for open fractures. By surgically cleaning and stabilizing the fracture, the risk of contamination and subsequent infection is minimized.

3.5 Better Cosmetic Outcome

ORIF can often provide a better cosmetic outcome compared to non-surgical treatments. By realigning the bone fragments, the surgeon can restore the natural shape and contour of the arm, resulting in a more aesthetically pleasing appearance.

4. Rehabilitation and Recovery

Following ORIF for humerus fractures, rehabilitation plays a crucial role in the patient’s recovery. The rehabilitation process typically involves:

  • Physical therapy: This helps restore range of motion, strength, and function of the arm. Physical therapists use various exercises and techniques to gradually increase the patient’s mobility and strength.
  • Occupational therapy: Occupational therapists focus on activities of daily living, such as dressing, grooming, and eating. They help patients regain independence and adapt to any functional limitations caused by the fracture.
  • Home exercises: Patients are often given specific exercises to perform at home to complement their in-clinic therapy. These exercises help maintain and further improve the progress made during formal rehabilitation sessions.

The duration of rehabilitation varies depending on the severity of the fracture and the individual’s healing process. It is important for patients to follow their rehabilitation plan diligently to achieve the best possible outcome.

5. Potential Complications

While ORIF for humerus fractures is generally a safe and effective procedure, there are potential complications that can arise. Some of these complications include:

  • Infection: Despite efforts to minimize the risk of infection, it can still occur. Prompt treatment with antibiotics and, in some cases, surgical debridement may be necessary to control the infection.
  • Nonunion: In some cases, the fractured bone fragments may fail to heal properly, resulting in nonunion. This may require additional surgical intervention, such as bone grafting, to promote healing.
  • Malunion: If the bone fragments heal in an incorrect position, malunion can occur. This can lead to functional limitations, deformity, and the need for corrective surgery.
  • Nerve or blood vessel injury: During the surgical procedure, there is a small risk of damaging nearby nerves or blood vessels. This can result in sensory or motor deficits, which may require further treatment.

It is important for patients to be aware of these potential complications and discuss them with their surgeon before undergoing ORIF for humerus fractures.


ORIF for humerus fractures is a surgical technique that offers several benefits compared to non-surgical treatment options. It provides improved alignment and stability, allows for early mobilization, reduces pain, lowers the risk of infection, and can result in a better cosmetic outcome. Rehabilitation plays a crucial role in the patient’s recovery, helping restore function and mobility. While complications can occur, the overall success rate of ORIF for humerus fractures is high. By understanding the techniques and benefits of this procedure, patients can make informed decisions about their treatment options and have realistic expectations for their recovery.
