Five bisphosphonates are currently available. In general, the most commonly prescribed are risedronic acid, alendronic acid, and pamidronic acid. Etidronic acid and other bisphosphonates may be appropriate therapies for selected patients but are less commonly used. None of these drugs should be used by people with severe kidney disease.

- Etidronate disodium The approved regimen is once daily for six months; a higher dose is more commonly used. No food, beverage, or medications should be consumed for two hours before and after taking. The course should not exceed six months, but repeat courses can be given after rest periods, preferably of three to six months duration.

- Pamidronate disodium in intravenous form: the approved regimen uses an infusion over four hours on each of three consecutive days, but a more commonly used regimen is over two to four hours for two or more consecutive or nonconsecutive days.

- Alendronate sodium is given as tablets once daily for six months; patients should wait at least 30 minutes after taking before eating any food, drinking anything other than tap water, taking any medication, or lying down (patient may sit).

- Tiludronate disodium are taken once daily for three months; they may be taken any time of day, as long as there is a period of two hours before and after resuming food, beverages, and medications.

- Risedronate sodium tablet taken once daily for 2 months is the prescribed regimen; patients should wait at least 30 minutes after taking before eating any food, drinking anything other than tap water, taking any medication, or lying down (patient may sit).

- Zoledronic acid is given as an intravenous infusion; a single dose is effective for two years. This is recommended for most people at high risk with active disease.

Calcitonin, also called calcitonin-salmon, is a synthetic copy of a polypeptide hormone secreted by the ultimobranchial gland of salmon. Miacalcin is administered by injection, three times per week or daily, for 6–18 months. Repeat courses can be given after brief rest periods. Miacalcin may be appropriate for certain patients, but is seldom used. Calcitonin is also linked to increased chance of cancer. Due to the increased risk of cancer, the European Medicines Agency (EMA) recommended that calcitonin be used only on a short-term basis for 3 conditions for which it had previously been approved in the European Union: Paget's disease, acute bone loss resulting from sudden immobilization, and hypercalcemia caused by cancer.

The EMA said it based its recommendations on a review of the benefits and risks of calcitonin-containing medicines. Conducted by the agency's Committee for Medicinal Products for Human Use (CHMP), the review encompassed available data from the companies that market these drugs, postmarketing safety data, randomized controlled studies, 2 studies of unlicensed oral calcitonin drugs, and experimental cancer studies, among other sources.

CHMP found that "a higher proportion of patients treated with calcitonin for long periods of time develop cancer of various types, compared with patients taking placebo." The increase in cancer rates ranged from 0.7% for oral formulations to 2.4% for the nasal formulation. CHMP concluded that the benefits of calcitonin for osteoporosis did not exceed the risks. The nasal spray's only indication is for osteoporosis, thus justifying the drug's removal from the market.

As a solution for injection or infusion, calcitonin should be administered for no more than 4 weeks to prevent acute bone loss resulting from sudden immobilization, and normally for no more than 3 months to treat Paget's disease, the EMA said. The agency did not specify a time frame for the short-term use of calcitonin for treating hypercalcemia caused by cancer.

Non-steroidal anti-inflammatory drugs (NSAIDs) and corticosteroids are most used in PDP treatment. These drugs inhibit cyclo-oxygenase activity and thereby prostaglandin synthesis. Since PGE is likely to be involved in periosteal bone formation and acroosteolysis, this is why these drugs can alleviate the polyarthritis associated with PDP. In addition, NSAIDs and corticosteroids decrease formation of inflammatory mediators, reducing inflammation and pain. In case of possible gastropathy, the COX-2 selective NSAID etorixocib is preferred.

Infliximab can reduce pain and arthritis in PDP. It is a monoclonal antibody that blocks the biological action of TNF-α (tumor necrosis factor-alpha). TNF-α is an inflammatory cytokine found in high levels in PDP and it is involved in the production of other inflammatory mediators which increase the expression of RANKL. RANKL is thought to increase bone resorption.

Medical management of OFC consists of Vitamin D treatment, generally alfacalcidol or calcitriol, delivered intravenously. Studies have shown that in cases of OFC caused by either end-stage renal disease or primary hyperparathyoidism, this method is successful not only in treating underlying hyperparathyoidism, but also in causing the regression of brown tumors and other symptoms of OFC.

Rheumatologic symptoms can be improved by treatment with biphosphonates, such as pamidronate or risedronate. Biphosphonates inhibit osteoclastic bone resorption and therefore reduce bone remodeling and alleviate painful polyarthritis.

In isolated cases, tamoxifen was effective in PDP treatment, especially for bone and joint pain. In PDP patients, high levels of nuclear receptors were found for steroids, which was the rationale to use tamoxifen, an estrogen receptor antagonist. Tamoxifen and several of its metabolites competitively bind to estrogen receptors on tissue targets, producing a nuclear complex that decreases DNA synthesis. Cells are in G and G phases. In vitro studies showed that tamoxifen acts as an estrogen agonist on bone and inhibits the resorbing activity of osteoclasts (disruption of bone tissue).

In especially severe cases of OFC, parathyroidectomy, or the full removal of the parathyroid glands, is the chosen route of treatment. Parathyroidectomy has been shown to result in the reversal of bone resorption and the complete regression of brown tumors. In situations where parathyroid carcinoma is present, surgery to remove the tumors has also led to the regression of hyperparathyroidism as well as the symptoms of OFC.

Bone transplants have proven successful in filling the lesions caused by OFC. A report showed that in 8 out of 11 instances where cavities caused by OFC were filled with transplanted bone, the lesion healed and the transplanted bone blended rapidly and seamlessly with the original bone.

What happens after your child is diagnosed with CRMO/CNO?

Find a doctor who has experience with patients with CRMO/CNO. CRMO/CNO in children is generally treated by a pediatric rheumatologist. Ask your doctor for a referral.

Why do we treat CRMO/CNO?

- Reduce inflammation

- Prevent bone damage and bone deformities

- Decrease pain

How is CRMO/CNO treated?

CRMO/CNO is different for each patient. Not every child responds to every treatment. Your doctor may need to try several medications before finding the one that works for your child. In severe cases, doctors may combine medications to treat the disease. Your doctor will work with you and your child to help find the best treatment.

For some CRMO/CNO patients, the disease can be managed with non-steroidal anti-inflammatory drugs (NSAIDs). NSAIDs are the first line treatment. However, if NSAIDs are not effective, or if your child does not tolerate NSAIDs well, second line treatments are available.

First line treatments include Naproxen (Aleve), Celecoxib (Celebrex) Meloxicam (Mobic), Piroxicam (Feldene), Indomethacin (Indocin), Diclofenac (Voltaren).

Second line treatments include corticosteroids (Prednisone/Prednisolone), Methotrexate (Otrexup, Rasuvo, Trexall), Sulfasalazine (Azulfidine), Pamidronate (Aredia), Zolendronic Acid (Zometa), Adalimumab (Humira), Etanercept (Enbrel), Infliximab (Remicade).

These medications are also used in children with other inflammatory and/or bone conditions. Side effects may occur while taking these medications. Your physician will have a discussion with you prior to starting any new treatment.

There is no cure, although curative therapy with bone marrow transplantion is being investigated in clinical trials. It is believed the healthy marrow will provide the sufferer with cells from which osteoclasts will develop. If complications occur in children, patients can be treated with vitamin D. Gamma interferon has also been shown to be effective, and it can be associated to vitamin D. Erythropoetin has been used to treat any associated anemia. Corticosteroids may alleviate both the anemia and stimulate bone resorption. Fractures and osteomyelitis can be treated as usual. Treatment for osteopetrosis depends on the specific symptoms present and the severity in each person. Therefore, treatment options must be evaluated on an individual basis. Nutritional support is important to improve growth and it also enhances responsiveness to other treatment options. A calcium-deficient diet has been beneficial for some affected people.

Treatment is necessary for the infantile form:

- Vitamin D (calcitriol) appears to stimulate dormant osteoclasts, which stimulates bone resorption

- Gamma interferon can have long-term benefits. It improves white blood cell function (leading to fewer infections), decreases bone volume, and increases bone marrow volume.

- Erythropoietin can be used for anemia, and corticosteroids can be used for anemia and to stimulate bone resorption.

Bone marrow transplantation (BMT) improves some cases of severe, infantile osteopetrosis associated with bone marrow failure, and offers the best chance of longer-term survival for individuals with this type.

In pediatric (childhood) osteopetrosis, surgery is sometimes needed because of fractures. Adult osteopetrosis typically does not require treatment, but complications of the condition may require intervention. Surgery may be needed for aesthetic or functional reasons (such as multiple fractures, deformity, and loss of function), or for severe degenerative joint disease.

The long-term-outlook for people with osteopetrosis depends on the subtype and the severity of the condition in each person.The severe infantile forms of osteopetrosis are associated with shortened life expectancy, with most untreated children not surviving past their first decade. seems to have cured some infants with early-onset disease. However, the long-term prognosis after transplantation is unknown. For those with onset in childhood or adolescence, the effect of the condition depends on the specific symptoms (including how fragile the bones are and how much pain is present). Life expectancy in the adult-onset forms is normal.

As of October 2015, asfotase alfa (Strensiq) has been approved by the FDA for the treatment of hypophosphatasia. Current management consists of palliating symptoms, maintaining calcium balance and applying physical, occupational, dental and orthopedic interventions, as necessary.

- Hypercalcemia in infants may require restriction of dietary calcium or administration of calciuretics. This should be done carefully so as not to increase the skeletal demineralization that results from the disease itself. Vitamin D sterols and mineral supplements, traditionally used for rickets or osteomalacia, should not be used unless there is a deficiency, as blood levels of calcium ions (Ca2+), inorganic phosphate (Pi) and vitamin D metabolites usually are not reduced.

- Craniosynostosis, the premature closure of skull sutures, may cause intracranial hypertension and may require neurosurgical intervention to avoid brain damage in infants.

- Bony deformities and fractures are complicated by the lack of mineralization and impaired skeletal growth in these patients. Fractures and corrective osteotomies (bone cutting) can heal, but healing may be delayed and require prolonged casting or stabilization with orthopedic hardware. A load-sharing intramedullary nail or rod is the best surgical treatment for complete fractures, symptomatic pseudofractures, and progressive asymptomatic pseudofractures in adult hypophosphatasia patients.

- Dental problems: Children particularly benefit from skilled dental care, as early tooth loss can cause malnutrition and inhibit speech development. Dentures may ultimately be needed. Dentists should carefully monitor patients’ dental hygiene and use prophylactic programs to avoid deteriorating health and periodontal disease.

- Physical Impairments and pain: Rickets and bone weakness associated with hypophosphatasia can restrict or eliminate ambulation, impair functional endurance, and diminish ability to perform activities of daily living. Nonsteroidal anti-inflammatory drugs may improve pain-associated physical impairment and can help improve walking distance]

- Bisphosphonate (a pyrophosphate synthetic analog) in one infant had no discernible effect on the skeleton, and the infant’s disease progressed until death at 14 months of age.

- Bone marrow cell transplantation in two severely affected infants produced radiographic and clinical improvement, although the mechanism of efficacy is not fully understood and significant morbidity persisted.

- Enzyme replacement therapy with normal, or ALP-rich serum from patients with Paget’s bone disease, was not beneficial.

- Phase 2 clinical trials of bone targeted enzyme-replacement therapy for the treatment of hypophosphatasia in infants and juveniles have been completed, and a phase 2 study in adults is ongoing.

Guidelines for management of patients up to 18 years with Langerhans cell histiocytosis has been suggested. Treatment is guided by extent of disease. Solitary bone lesion may be amenable through excision or limited radiation, dosage of 5-10 Gys for children, 24-30 Gys for adults. However systemic diseases often require chemotherapy. Use of systemic steroid is common, singly or adjunct to chemotherapy. Local steroid cream is applied to skin lesions. Endocrine deficiency often require lifelong supplement e.g. desmopressin for diabetes insipidus which can be applied as nasal drop. Chemotherapeutic agents such as alkylating agents, antimetabolites, vinca alkaloids either singly or in combination can lead to complete remission in diffuse disease.

Treatment is usually surgical removal of the gland(s) containing adenomas, but medication may also be required.

Paget's disease of the breast is a type of cancer of the breast. Treatment usually involves a lumpectomy or mastectomy to surgically remove the tumour. Chemotherapy and/or radiotherapy may be necessary, but the specific treatment often depends on the characteristics of the underlying breast cancer.

Invasive cancer or extensive ductal carcinoma "in situ" is primarily treated with modified radical mastectomies. The procedure consists in the removal of the breast, the lining over the chest muscles and a part of the lymph nodes from under the arm. In cases of noninvasive cancers, simple mastectomies are performed in which only the breast with the lining over the chest muscles is removed.

Patients suffering from cancer that has not spread beyond the nipple and the surrounding area are often treated with breast-conserving surgery or lumpectomy. They usually undergo radiation therapy after the actual procedure to prevent recurrence. A breast-conserving surgery consists in the removal of the nipple, areola and the part of the breast that is affected by cancer.

In most cases, adjuvant treatment is part of the treatment schema. This type of treatment is normally given to patients with cancer to prevent a potential recurrence of the disease. Whether adjuvant therapy is needed depends upon the type of cancer and whether the cancer cells have spread to the lymph nodes. In Paget's disease, the most common type of adjuvant therapy is radiation following breast-conservative surgery.

Adjuvant therapy may also consist of anticancer drugs or hormone therapies. Hormonal therapy reduces the production of hormones within the body, or prevents the hormones from stimulating the cancer cells to grow, and it is commonly used in cases of invasive cancer by means of drugs such as tamoxifen and anastrozole.

The surgical removal of one or more of the parathyroid glands is known as a parathyroidectomy; this operation was first performed in 1925. The symptoms of the disease, listed above, are indications for surgery. Surgery reduces all cause mortality as well as resolving symptoms. However, cardiovascular mortality is not significantly reduced.

The 2002 NIH Workshop on Asymptomatic Primary Hyperparathyroidism developed criteria for surgical intervention . The criteria were revised at the Third International Workshop on the Management of Asymptomatic Primary Hyperparathyroidism . These criteria were chosen on the basis of clinical experience and observational and clinical trial data as to which patients are more likely to have end-organ effects of primary hyperparathyroidism (nephrolithiasis, skeletal involvement), disease progression if surgery is deferred, and the most benefit from surgery. The panel emphasized the need for parathyroidectomy to be performed by surgeons who are highly experienced and skilled in the operation. The Third International Workshop guidelines concluded that surgery is indicated in asymptomatic patients who meet any one of the following conditions:

- Serum calcium concentration of 1.0 mg/dL (0.25 mmol/L) or more above the upper limit of normal

- Creatinine clearance that is reduced to <60 mL/min

- Bone density at the hip, lumbar spine, or distal radius that is more than 2.5 standard deviations below peak bone mass (T score <-2.5) and/or previous fragility fracture

- Age less than 50 years

Operative intervention can be delayed in patients over 50 years of age who are asymptomatic or minimally symptomatic and who have serum calcium concentrations <1.0 mg/dL (0.2 mmol/L) above the upper limit of normal, and in patients who are medically unfit for surgery

More recently, three randomized controlled trials have studied the role of surgery in patients with asymptomatic hyperparathyroidism. The largest study reported that surgery resulted in an increase in bone mass, but no improvement in quality of life after one to two years among patients in the following groups:

- Untreated, asymptomatic primary hyperparathyroidism

- Serum calcium between 2.60–2.85 mmol/liter (10.4–11.4 mg/dl)

- Age between 50 and 80 yr

- No medications interfering with Ca metabolism

- No hyperparathyroid bone disease

- No previous operation in the neck

- Creatinine level < 130 µmol/liter (<1.47 mg/dl)

Two other trials reported improvements in bone density and some improvement in quality of life with surgery.

Depending on the level of pain and damage suffered by a patient, a physician will recommend a treatment regimen that will relieve symptoms. Some of the most common recommendations include avoiding activities that make the pain worse, ice the knee for 20 to 30 minutes throughout the day to reduce inflammation, use over the counter anti-inflammatory medications, paracetamol (acetaminophen) and physical therapy.

Topical creams and patches can also be used for pain treatment and they have been proven to reduce pain by 33 to 57%.

Exercises can help increase range of motion and flexibility as well as help strengthen the muscles in the leg. Physical therapy and exercise are often effective in reducing pain and improving function. Working with a physical therapist to find exercises that promote function without risking further injury is effective for most patients. Many of the exercises used can be performed while sitting in a chair or standing in place. They are performed so that additional stress or weight is not placed on the knee joint. Water exercises are highly recommended along with the use of elastic bands.

Supportive devices like knee braces can be used. In most cases, the arthritis is centered on a single side of the knee, so braces are effective in providing stability to one side. Two different forms of braces are available. A support brace provides the aid the entire knee requires, where an up-loader brace shifts the pressure away from the specific part of the knee that is experiencing the pain. Shoes or inserts that are considered to be energy absorbing are found useful for some patients as well as walking devices like a cane. Shoe insoles that are fitted to correct flat feet have provided relief to many patients.

The use of oral steroids and anti-inflammatory medicines help to reduce the amount of inflammation and pain felt in the knee. If over the counter medicines like ibuprofen or naproxen are not strong enough, prescription strength medicines are used. If oral medicine and physical therapy don't help your knee enough, doctors may consider giving patients injections with pain medicine. Hyaluronic acid is present in the knee, but injections of it can be used to protect the joint when the cartilage becomes thinner and can't do it alone. These injections can provide more pain relief than oral medications lasting from six months to a year.

Surgery is the final option but may be required to relieve symptoms. Arthroscopy is performed through tiny cuts where damaged parts of the knee can be removed. Osteotomy is performed to reshape the bones in the knee and is only performed if one side of the knee is damaged. Arthroplasty is a replacement surgery where an artificial joint is used.

Low level laser therapy can be considered for relief of pain and stiffness associated with osteoarthritis.

Culture and sensitivity of the wound site determines the choice of antibiotic. Repeated culture and sensitivity testing is often carried out in OM since the treatment is prolonged and antibiotic resistance may occur, when a change in the drug may be required.

Excellent for single-focus disease. With multi-focal disease 60% have a chronic course, 30% achieve remission and mortality is up to 10%.

Most hip fractures are treated surgically by implanting an orthosis. Surgical treatment outweighs the risks of nonsurgical treatment which requires extensive bedrest. Prolonged immobilization increases risk of thromboembolism, pneumonia, deconditioning, and decubitus ulcers. Regardless, the surgery is a major stress, particularly in the elderly. Pain is also significant, and can also result in immobilization, so patients are encouraged to become mobile as soon as possible, often with the assistance of physical therapy. Skeletal traction pending surgery is not supported by the evidence. Regional nerve blocks are useful for pain management in hip fractures.

Red blood cell transfusion is common for people undergoing hip fracture surgery due to the blood loss sustained during surgery and from the injury. Adverse effects of blood transfusion may occur and are avoided by restrictive use of blood transfusion rather than liberal use. Restrictive blood transfusion is based on symptoms of anemia and thresholds lower than the 10 g/dL haemoglobin used for liberal blood transfusion.

If operative treatment is refused or the risks of surgery are considered to be too high the main emphasis of treatment is on pain relief. Skeletal traction may be considered for long term treatment. Aggressive chest physiotherapy is needed to reduce the risk of pneumonia and skilled rehabilitation and nursing to avoid pressure sores and DVT/pulmonary embolism Most people will be bedbound for several months. Non-operative treatment is now limited to only the most medically unstable or demented patients, or those who are nonambulatory at baseline with minimal pain during transfers.

Rehabilitation has been proven to increase daily functional status. It is unclear if the use of anabolic steroids effects recovery.

There have been attempts to control the inflammation using drugs that work in other conditions where inflammation is a problem. The most successful of these are steroids, but they have side effects when used long term. Other medications, including methotrexate, colchicine and canakinumab, have been tried with some success. Otherwise, the treatment is supportive, or aimed solely at controlling symptoms and maximizing function.

An endocrine bone disease is a bone disease associated with a disorder of the endocrine system. An example is osteitis fibrosa cystica.

The medication(s) listed below have been approved by the Food and Drug Administration (FDA) as orphan products for treatment of this condition. Learn more orphan products.

Pathologic fractures in children and adolescents can result from a diverse array of disorders namely; metabolic, endocrine, neoplastic, infectious, immunologic, and genetic skeletal dysplasias.

- Osteogenesis imperfecta

- Primary hyperparathyroidism

- Simple bone cyst

- Aneurismal bone cyst

- Disuse osteoporosis

- Chronic osteomyelitis

- Osteogenesis imperfecta

- Rickets

- Renal osteodystrophy

- Malignant infantile osteopetrosis

- juvenile osteoporosis

- juvenile rheumatoid arthritis

In circumstances where other pathologies are excluded (for example, cancer), a pathologic fracture is diagnostic of osteoporosis irrespective of bone mineral density.

Some patients have no symptoms, spontaneous remission, or a relapsing/remitting course, making it difficult to decide whether therapy is needed. In 2002, authors from Sapienza University of Rome stated on the basis of a comprehensive literature review that "clinical observation without treatment is advisable when possible."

Therapeutic options include surgery, radiation therapy, and chemotherapy. Surgery is used to remove single lymph nodes, central nervous system lesions, or localized cutaneous disease. In 2014, Dalia and colleagues wrote that for patients with extensive or systemic Rosai–Dorfman disease, "a standard of care has not been established" concerning radiotherapy and chemotherapy.

Infantile cortical hyperostosis is a self-limited condition, meaning that the disease resolves on its own without treatment, usually within 6–9 months. Long-term deformities of the involved bones, including bony fusions and limb-length inequalities, are possible but rare.
