An uncommon instance of endogenous aseptic inflammation of the bone marrow with an unclear etiology is known as chronic recurrent multifocal osteomyelitis (CRMO). It can progress in a subacute or primary chronic manner. It is generally accepted that CRMO is primarily caused by autoimmune processes because the ailment is frequently associated with other autoimmune conditions. CRMO affects girls more frequently than boys, with a peak age of 10 years, and was first identified in 1972 by Giedeon et al.



Children and young adults are susceptible to the disease of chronic recurrent multifocal osteomyelitis (CRMO). The disease’s subtle onset of local discomfort and edema in damaged bones is how it manifests clinically. Its course consists of sporadic flare-ups and remissions, with successive bones being damaged. Although an autoinflammatory illness with bone inflammation may be the reason, the etiology of CRMO is yet unknown.

Multiple lucencies, identifiable zones of patchy but dense sclerosis, cortical thickening from periosteal new bone growth, and enlarged bone size are all radiographic characteristics of this lesion. Numerous treatment plans had only produced a minimal or transient response. Until recently, it was believed that just 0.4 out of every 100,000 persons would develop CRMO. CRMO seems to be more widespread than that as it gains more recognition. CRMO may even be more frequent than bone infections. The typical age at which CRMO begins is 9 to 10 years old. More females than boys are impacted.


The disorder CRMO is an auto-inflammatory condition, which means that even when there is no infection, the immune system assaults the bones and causes inflammation. A tiny percentage of CRMO patients have a hereditary component. More than one member of some families has CRMO.



The main complaint is bone discomfort. The affected area is typically tender and painful to press on. The person may avoid using the injured body part because of the pain. Certain CRMO patients may develop arthritis (joint swelling). During an active illness, fatigue is frequent. CRMO has a sneaky start of symptoms and, according to some accounts, can take up to 12 months on average to be diagnosed. Local discomfort, functional impotence, erythema, and cramping are frequently the patient’s initial symptoms and are frequently misdiagnosed for bacterial osteomyelitis.

At the time of diagnosis, most patients have an average of five bone lesions, and some of them may not be experiencing any symptoms. A cohort of 178 pediatric CRMO patients in France showed a 70% multifocal bone lesion prevalence, with an average of 2 to 9 lesions per patient at the time of diagnosis, and a 30% single bone lesion prevalence.



Examination, imaging (such as X-rays, bone scans, or MRI), bone biopsy, and laboratory (blood) testing all contribute to the diagnosis. Most people’s lab results are normal, however, some people may have anemia (insufficient oxygen carried by the blood throughout the body) or have increased levels of inflammatory markers (ESR, CRP).

On an x-ray, bone scan, or MRI, damaged or changed bone might be visible. The most accurate imaging technique for detecting indications of CRMO is MRI. In order to rule out infection or malignancy, a bone biopsy may be required. A biopsy in CRMO typically reveals either long-lasting or short-term (acute) irritation.

Homeopathic Treatment:


The severity of the disease affects how osteomyelitis is treated. While simply using antibiotics to treat acute osteomyelitis, doctors use surgery to cure chronic osteomyelitis. Homeopathic treatment for osteomyelitis has been shown to be beneficial. Additionally, there are specialized homeopathic medications that can treat osteomyelitis. Professional homeopaths frequently deal with joint problems, bone injuries, and wound infections.

Doctors occasionally discover that acupuncture works well to reduce inflammation, discomfort, fever, and swelling. Non-steroidal anti-inflammatory agents are the primary line of treatment, and they have response rates as high as 80%. Corticoids, interferon, calcitonin, azithromycin, sulfasalazine, and bisphosphonates are some of the other alternatives mentioned. Blockers of the tumor necrosis factor (TNF) may be utilized in extreme situations.

Biologic drugs like infliximab, an IV infusion, or injectable pharmaceuticals like etanercept, adalimumab, or anakinra are some more therapeutic possibilities. Both methotrexate and biological drugs inhibit the immune system. People who take these medications have a higher risk of infection and should be examined by a doctor if they experience a fever or other infection-related symptoms.

Before beginning biological drugs, individuals must have a TB screening. Chronic recurrent multifocal osteomyelitis is also treated with bisphosphonates like pamidronate and zoledronic acid. These medications are IV infusions used to treat osteoporosis and other bone disorders. After the infusion, bisphosphonates can produce symptoms similar to the flu for a few days.


crmo-7Living with chronic recurrent multifocal osteomyelitis frequently entails taking medication and scheduling follow-up appointments with a rheumatologist. Some people need to limit their activity to avoid serious injury or bone deterioration, depending on which bones are involved. If a spine fracture happens, those with spinal involvement are at risk for suffering significant injuries.

Activity limitations should be discussed with a doctor by people with CRMO. It is possible for CRMO to disappear in certain persons, either temporarily or permanently. Others may experience persistent pain (amped musculoskeletal pain) that is unresponsive to treatment even when CRMO is under control. A pain clinic may be needed to address this kind of discomfort.
