Swelling in the Left Arm After Proximal Humerus Fracture - Orthopedics

More Info

Hello, thank you for your question regarding your mother's condition following her proximal humerus fracture. It’s understandable to be concerned about swelling and any potential complications after such an injury.

Swelling in the arm after a proximal humerus fracture can be attributed to several factors. Firstly, it’s important to note that swelling is a common response to injury and surgery. The body’s inflammatory response can lead to fluid accumulation in the tissues surrounding the injury site, which may extend down the arm, affecting the forearm and hand. This is often referred to as post-traumatic edema.

In your mother’s case, the fact that the swelling in the upper arm has improved is a positive sign. However, persistent swelling in the forearm and hand, especially if it has been present for 2-3 weeks, warrants further evaluation. The swelling could be due to a few reasons:
1. Fluid Accumulation: After a fracture, the body may retain fluid in the injured area. This can be exacerbated by immobilization, as movement helps promote circulation and fluid drainage.

2. Compartment Syndrome: Although less common, it’s essential to be aware of compartment syndrome, a condition where increased pressure within a muscle compartment can lead to muscle and nerve damage. However, this typically presents with severe pain, numbness, or tingling, and since your mother reports no pain in the elbow, this may be less likely.

3. Joint Issues: The presence of a bony prominence on the outer side of the elbow could indicate a possible misalignment or a bony irregularity. While your mother does not report pain, it’s crucial to ensure that there is no underlying issue such as a malunion or nonunion of the fracture, which could lead to complications in the healing process.

4. Lymphedema: Sometimes, after an injury, the lymphatic system may be affected, leading to lymphedema, which is the accumulation of lymph fluid in the tissues. This can cause swelling that persists even after the initial injury has healed.

Given these possibilities, it’s advisable to have your mother evaluated by her orthopedic surgeon or a healthcare provider. They may recommend imaging studies, such as an X-ray or MRI, to assess the healing of the fracture and to rule out any complications. Additionally, they can evaluate the range of motion and function of the elbow and arm to ensure that rehabilitation is progressing appropriately.

In the meantime, gentle range-of-motion exercises, as tolerated, can help reduce swelling and improve circulation. Elevating the arm and applying cold compresses may also assist in managing the swelling. However, it’s essential to follow the advice of her healthcare provider regarding any exercises or treatments.

In summary, while some swelling is expected after a proximal humerus fracture, persistent swelling in the forearm and hand should be evaluated to rule out any complications. Regular follow-ups with her healthcare provider will be crucial in ensuring a smooth recovery process. Thank you for your inquiry, and I hope your mother experiences a swift and complete recovery.
