Brodie’s abscess is a subacute form of osteomyelitis, causing vague symptoms such as bone pain and tenderness. It can be difficult to identify, but medical imaging can show changes in the bone. Treatment involves antibiotics and surgery in some cases, with amputation as a last resort. Prompt evaluation and treatment are important to prevent permanent damage.
Brodie’s abscess is a bone disease seen most commonly in long bones such as the femur and tibia. It is a form of osteomyelitis or bone infection and is considered a subacute form, as the symptoms differ from those seen in patients with acute osteomyelitis. Treatment involves giving drugs to kill the causative organisms, and in some cases, surgery may be needed to drain and clean the abscess. In rare cases, amputation is required due to bone damage.
In osteomyelitis, infectious organisms such as staph bacteria enter the bone and begin to reproduce. The subacute forms cause vague symptoms such as bone pain, tenderness of the skin over the site, and general feelings of being unwell. Brodie’s abscess can be difficult to identify as the symptoms are often general and very vague, and it may take some time to pinpoint the source of the symptoms.
Medical imaging studies of a patient with this type of abscess will show a change in the bone at the site of the abscess. In some patients, this takes the form of a thin line, while in others, a Brodie’s abscess may appear as a round or oblong section of bone filled with pus and fluid. Sometimes, the abscess will start to drain, causing infection and inflammation around the bone. Most commonly, the infection is located in the metaphysis, the area of the bone between the shaft and the end, and in children such infections can interfere with bone development.
Once diagnosed, Brodie’s abscess can be treated with antibiotic medications. The antibiotics will penetrate the bone, killing the bacteria and allowing the inflammation and infection to resolve. Abscess drainage can be performed surgically for large pus formations. Surgery may also be used to debride dead tissue if the infection has spread above the bone location. In cases where the subacute abscess can persist for an extended period of time, causing chronic pain and inflammation, the limb sometimes has to be amputated.
People of all ages and fitness levels can develop this type of abscess and can encounter it in a variety of circumstances. Prompt evaluation and treatment of obvious pain, swelling, and inflammation are critical to identifying and treating conditions like Brodie’s abscess before they cause permanent damage. Seeing a specialist can be helpful for patients, as a regular doctor may not have much experience with the type of inflammation in question and may miss the warning signs.
