Humerus Fractures, Treatment & Surgery

The treatment that are most well-suited for your distal humerus fracture depend on a number of factors, including age, current health, the severity of the fracture and history with various medications and treatments. Humerus fracture, which is a complete or partial breakage of the upper arm bone, is most commonly caused by trauma, particularly a fall, and accounts for 3% of all fractures.

Distal Humerus Fracture Diagnosis

A humerus fracture can reduce your ability to easily perform daily tasks. If you have any reason to think that you may have a fracture in your humerus, it is important to seek medical attention. To best diagnose your injury, your doctor will ask a series of questions about your health history and how the injury occurred. If the specific location of the breakage is not known, one or more of these tests will help locate its exact spot:

  • X-Ray (Radiograph) – This is the first test done to determine where the fracture is located and the extent of the injury. It is done using electromagnetic radiation that is sent through the shoulder and upper arm area. Bone absorbs the radiation, making it appear on the transposed image. This is usually a sufficient test to see the location and severity of the fracture.
  • Computed Tomography Scan (CT or CAT scan) – A CAT scan is a combination of X-Ray and computer technologies and may be used if the radiograph is not clear.
  • Magnetic Resonance Imaging (MRI) – If further imaging is needed, or the patient cannot be exposed to more radiation, an MRI will be done. This uses magnetic fields that generate vibrations through radio waves aimed at the shoulder and upper arm area. These vibrations are then transposed onto a high-definition computer image.

Nonsurgical Treatment for Distal Humerus Fractures

If the humerus fracture is stable or not displaced, a splint may be used to immobilize it while it heals. This type of nonsurgical approach will be monitored throughout the healing process to ensure there are no complications and that the bone is in fact healing as it should. Once the doctor is certain that there are no bone fragments or anything out of place, the patient may be able to start moving it after a few weeks. This will help speed the recovery time. The patient will still be advised to avoid lifting anything heavy until the fracture has healed completely.

Surgery for Distal Humerus Fractures

In cases where a humerus fracture has been displaced or the bone has lacerated the skin, surgery will be required. The aim of most humerus fracture surgeries is to realign the bones and guide them as they heal. The vast majority of humerus fractures are treated using one of the following techniques:

  • Internal Fixation – Through the use of pins, metal plates and screws, one or all of these pieces will be affixed to the bone to help reconnect the broken pieces and stabilize them for healing. The incision is typically made behind the elbow. Because of this, after surgery the patient will likely have to remain in a splint to reduce any strain on the incision.
  • Elbow Replacement – This is highly unique, but when the lower part of the humerus has been damaged, the elbow may have received equal force of the impact and may need to be replaced. This is most common in elderly patients. A metal or plastic implant will be used to replace the elbow. The procedure is similar to that of a hip or knee replacement.

Distal Humerus Fracture Research

Much of the research surrounding humerus fractures has to do with those that occur in the elderly. Because the elderly are more inclined to have reduced bone density, they are at a significantly higher risk of breaking one of their bones. The humerus is a particular risk because it is often broken when a person tries to brace their fall or falls on their side. More specifically, proximal humerus fractures account for 10% of all fractures in people over the age of 65.

In the elderly, one of the main concerns is the length of time it takes for the humerus to heal. During this time, a person is limited in the number of activities they can perform. A recent study done by the Mayo Clinic Department of Orthopedic Surgery took a look at one of the more controversial treatment methods for proximal surgeries in the humerus. These have long been controversial because they are believed to limit the ability of the elderly to move and therefore can lead to other health concerns, such as blood clots and death.

In the study, a hybrid approach of an implant combined with internal fixation led to fewer complications and better mobility following the surgery. In similar study by Brunner, similar results were found. Additionally, it was determined that the length and number of screws used to position the bone had significance on the overall outcome of the patients’ health. It was not determined that the elderly were affected by the longer recovery times and limited mobility during the recovery time.

As research on surgery to repair proximal humerus fractures is ongoing, it is a good idea for your conversation about it with your doctor to be ongoing as well.
