Malunion

A malunion is when a fractured bone doesn’t heal properly. Some ways that it shows is by having the bone being twisted, shorter, or bent. Malunions can occur by having the bones improperly aligned when immobilized, having the cast taken off too early, or never seeking medical treatment after the break.

Malunions are painful and commonly produce swelling around the area, possible immobilization, and deterioration of the bone and tissue.

Signs and symptoms

Malunions are presented by excessive swelling, twisting, bending, and possibly shortening of the bone. Patients may have trouble placing weight on or near the malunion. However, most commonly the presentation of a bend in the bone exhibits the diagnosis of a malunion.

Diagnosis

An X-ray is essential for the proper diagnosis of a malunion. The doctor will look into the patient’s history and the treatment process for the bone fracture. Oftentimes a CT scan and probably a MRI are also used in diagnosis. MRI are used to check of cartilage and ligament issues that developed due to the malunion and misalignment. CT scans are used to locate normal or abnormal structures within the body and to help during procedures to guide the placement of instruments and/or treatments.
