Malunion is a medical term that refers to the improper healing of a broken bone in an abnormal position. This can occur when the bone fragments are not properly aligned during the healing process. Malunion can lead to deformity, pain, and loss of function in the affected area.

Causes

The primary cause of malunion is improper alignment of the bone fragments during the healing process. This can occur due to a variety of reasons, including inadequate immobilization of the fracture, premature weight-bearing, or inadequate surgical intervention. Other factors that can contribute to malunion include the patient's age, overall health, and the type and location of the fracture.

Symptoms

The symptoms of malunion can vary depending on the location and severity of the malunion. Common symptoms include pain, deformity, and loss of function in the affected area. In some cases, the patient may also experience difficulty moving the affected limb or joint.

Diagnosis

Diagnosis of malunion typically involves a physical examination and imaging tests, such as X-rays or CT scans. These tests can help to determine the alignment of the bone fragments and the extent of the malunion.

Treatment

Treatment for malunion typically involves surgery to realign the bone fragments. This may involve cutting the bone and realigning it, or it may involve grafting bone from another part of the body to help support the malunion. In some cases, physical therapy may also be recommended to help improve function and mobility in the affected area.
