The choice of surgical versus non-surgical treatments for osteochondritis dissecans is controversial. Consequently, the type and extent of surgery necessary varies based on patient age, severity of the lesion, and personal bias of the treating surgeon—entailing an exhaustive list of suggested treatments. A variety of surgical options exist for the treatment of persistently symptomatic, intact, partially detached, and completely detached OCD lesions. Post-surgery reparative cartilage is inferior to healthy hyaline cartilage in glycosaminoglycan concentration, histological, and immunohistochemical appearance. As a result, surgery is often avoided if non-operative treatment is viable.

Candidates for non-operative treatment are limited to skeletally immature teenagers with a relatively small, intact lesion and the absence of loose bodies. Non-operative management may include activity modification, protected weight bearing (partial or non-weight bearing), and immobilization. The goal of non-operative intervention is to promote healing in the subchondral bone and prevent potential chondral collapse, subsequent fracture, and crater formation.

Once candidates for treatment have been screened, treatment proceeds according to the lesion's location. For example, those with OCD of the knee are immobilized for four to six weeks or even up to six months in extension to remove shear stress from the involved area; however, they are permitted to walk with weight bearing as tolerated. X-rays are usually taken three months after the start of non-operative therapy; if they reveal that the lesion has healed, a gradual return to activities is instituted. Those demonstrating healing by increased radiodensity in the subchondral region, or those whose lesions are unchanged, are candidates to repeat the above described three-month protocol until healing is noted.

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.

A variety of methods may be used to treat the most common being the total hip replacement (THR). However, THRs have a number of downsides including long recovery times and short life spans (of the hip joints). THRs are an effective means of treatment in the older population; however, in younger people they may wear out before the end of a person's life.

Other technicques such as metal on metal resurfacing may not be suitable in all cases of avascular necrosis; its suitability depends on how much damage has occurred to the femoral head. Bisphosphonates which reduces the rate of bone breakdown may prevent collapse (specifically of the hip) due to AVN.

Other treatments include core decompression, where internal bone pressure is relieved by drilling a hole into the bone, and a living bone chip and an electrical device to stimulate new vascular growth are implanted; and the free vascular fibular graft (FVFG), in which a portion of the fibula, along with its blood supply, is removed and transplanted into the femoral head. A 2012 Cochrane systematic review noted that no clear improvement can be found between people who have had hip core decompression and participate in physical therapy, versus physical therapy alone. More research is need to look into the effectiveness of hip core decompression for people with sickle cell disease.

Progression of the disease could possibly be halted by transplanting nucleated cells from bone marrow into avascular necrosis lesions after core decompression, although much further research is needed to establish this technique.

Bisphosphonate therapy has been suggested as a first-line therapeutic option in many case reports and series.

Treatment with tumor necrosis factor alpha antagonists (TNF inhibitors) have been tried in few patients with limited success. Other drugs that are used in psoriatic arthritis, to which SAPHO syndrome is closely related, have also been used in this condition. They include NSAIDs, corticosteroids, sulfasalazine, methotrexate, ciclosporin and leflunomide.

Some patients have responded to antibiotics. The rationale for their use is that Propionibacterium acnes, a bacterium known for its role in acne, has been isolated from bone biopsies of SAPHO patients.

Treatment is difficult, often requiring a joint replacement. Spontaneous improvement occasionally happens and some juxta-articular lesions do not progress to collapse. Other treatments include immobilization and osteotomy of the femur. Cancellous bone grafts are of little help.

Prevention is a more successful strategy than treatment. By using the most conservative decompression schedule reasonably practicable, and by minimizing the number of major decompression exposures, the risk of DON may be reduced. Prompt treatment of any symptoms of decompression sickness (DCS) with recompression and hyperbaric oxygen also reduce the risk of subsequent DON.

The goals of treatment are to decrease pain, reduce the loss of hip motion, and prevent or minimize permanent femoral head deformity so that the risk of developing a severe degenerative arthritis as adult can be reduced. Assessment by a pediatric orthopaedic surgeon is recommended to evaluate risks and treatment options. Younger children have a better prognosis than older children.

Treatment has historically centered on removing mechanical pressure from the joint until the disease has run its course. Options include traction (to separate the femur from the pelvis and reduce wear), braces (often for several months, with an average of 18 months) to restore range of motion, physiotherapy, and surgical intervention when necessary because of permanent joint damage. To maintain activities of daily living, custom orthotics may be used. Overnight traction may be used in lieu of walking devices or in combination. These devices internally rotate the femoral head and abduct the leg(s) at 45°. Orthoses can start as proximal as the lumbar spine, and extend the length of the limbs to the floor. Most functional bracing is achieved using a waist belt and thigh cuffs derived from the Scottish-Rite orthosis. These devices are typically prescribed by a physician and implemented by an orthotist. Clinical results of the Scottish Rite orthosis have not been good according to some studies, and its use has gone out of favor. Many children, especially those with the onset of the disease before age 6, need no intervention at all and are simply asked to refrain from contact sports or games which impact the hip. For older children (onset of Perthes after age 6), the best treatment option remains unclear. Current treatment options for older children over age 8 include prolonged periods without weight bearing, osteotomy (femoral, pelvic, or shelf), and the hip distraction method using an external fixator which relieves the hip from carrying the body's weight. This allows room for the top of the femur to regrow. The Perthes Association has a "library" of equipment which can be borrowed to assist with keeping life as normal as possible, newsletters, a helpline, and events for the families to help children and parents to feel less isolated.

While running and high-impact sports are not recommended during treatment for Perthes disease, children can remain active through a variety of other activities that limit mechanical stress on the hip joint. Swimming is highly recommended, as it allows exercise of the hip muscles with full range of motion while reducing the stress to a minimum. Cycling is another good option as it also keeps stress to a minimum. Physiotherapy generally involves a series of daily exercises, with weekly meetings with a physiotherapist to monitor progress. These exercises focus on improving and maintaining a full range of motion of the femur within the hip socket. Performing these exercises during the healing process is essential to ensure that the femur and hip socket have a perfectly smooth interface. This will minimize the long-term effects of the disease. Use of bisphosphonate such as zoledronate or ibandronate is currently being investigated, but definite recommendations are not yet available.

Perthes disease is self-limiting, but if the head of femur is left deformed, long-term problems can occur. Treatment is aimed at minimizing damage while the disease runs its course, not at 'curing' the disease. It is recommended not to use steroids or alcohol as these reduce oxygen in the blood which is needed in the joint. As sufferers age, problems in the knee and back can arise secondary to abnormal posture and stride adopted to protect the affected joint. The condition is also linked to arthritis of the hip, though this appears not to be an inevitable consequence. Hip replacements are relatively common as the already damaged hip suffers routine wear; this varies by individual, but generally is required any time after age 50.

Operations that attempt to restore a blood supply to the lunate may be performed.

Depending on the stage the disease is in when it is discovered, varying treatments are applied.

If X-rays show a mostly intact lunate (not having lost a great deal of size, and not having been compressed into a triangular shape), but an MRI shows a lack of blood flow to the bone, then revascularization is normally attempted. Revascularization techniques, usually involving a bone graft taken elsewhere from the body — often held in place by an external fixator for a period of weeks or months — have been successful at stages as late as 3B, although their use at later stages (like most treatments for Kienböck's) is controversial.

One conservative treatment option would be using an Ultrasound Bone Stimulator, which uses low-intensity pulsed ultrasound to increase vascular endothelial growth factor (VEG-F) and increase blood flow to the bone.

Some Kienböck's patients present with an abnormally large difference in length between the radius and the ulna, termed "ulnar variance", which is hypothesized to cause undue pressure on the lunate, contributing to its avascularity. In cases with such a difference, "radial shortening" is commonly performed. In this procedure, the radius (the lateral long bone) is shortened by a given length, usually between 2 and 5 mm, to relieve the pressure on the dying lunate. A titanium plate is inserted to hold the newly shortened bone together.

During Stage 3, the lunate has begun to break apart due to the pressure of the surrounding bones. This causes sharp fragments of bone to float between the joints, causing excruciating pain. At this point, the lunate is ready for removal. The most frequently performed surgery is the "Proximal Row Carpectomy", where the lunate, scaphoid and triquetrum are extracted. This greatly limits the range of motion of the wrist, but pain relief can be achieved for longer than after the other surgeries.

Another surgical option for this stage is a titanium, silicon or pyrocarbon implant that takes place of the lunate, though doctors shy from this due to a tendency of the implant to smooth the edges of the surrounding bones, thus causing painful pinched nerves when the bones slip out of place.

After the lunate is removed, another procedure, "ulnar shortening" can be performed. This relieves pressure on the newly formed wrist joint of the pisiform, hamate and capitate. Depending on the surgeon, the procedure may be performed the same way as the "radial shortening" where a small section is removed, or the entire top of the ulna may be excised.

At Stage 4, the lunate has completely disintegrated and the other bones in the wrist have radiated downward to fill in the void. The hand now has a deformed, crippled appearance. The only procedure that can be done is the "total wrist fusion", where a plate is inserted on the top of the wrist from the radius to the carpals, effectively freezing all flexion and movement in the wrist. Rotation is still possible as it is controlled by the radius and ulna.

This is currently the last and most complete surgical option for Kienböck's sufferers.

Most of the treatments described here are not mutually exclusive — meaning that a single patient may receive many of them in his quest to relieve pain. For instance, some patients have had casting, bone graft, radial shortening, proximal row carpectomy, and wrist fusion, all on the same hand.

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.

One of the major concerns is bone density and bone loss. Non-hormonal bisphosphonates increase bone strength and are available as once-a-week prescription pills. Metastron also known as strontium-89 chloride is an intravenous medication given to help with the pain and can be given in three month intervals. Generic Strontium Chloride Sr-89 Injection UPS, manufactured by Bio-Nucleonics Inc., it is the generic version of Metastron. Astra zantec is currently under review as to the benefits in bone cancer.

Chondroblastoma has not been known to spontaneously heal and the standard treatment is surgical curettage of the lesion with bone grafting. To prevent recurrence or complications it is important to excise the entire tumor following strict oncologic criteria. However, in skeletally immature patients intraoperative fluoroscopy may be helpful to avoid destruction of the epiphyseal plate. In patients who are near the end of skeletal growth, complete curettage of the growth plate is an option. In addition to curettage, electric or chemical cauterization (via phenol) can be used as well as cryotherapy and wide or marginal resection. Depending on the size of the subsequent defect, autograft or allograft bone grafts are the preferred filling materials. Other options include substituting polymethylmethacrylate (PMMA) or fat implantation in place of the bone graft. The work of Ramappa "et al" suggests that packing with PMMA may be a more optimal choice because the heat of polymerization of the cement is thought to kill any remaining lesion.

Both radiotherapy and chemotherapy are not commonly used. Radiotherapy has been implemented in chondroblastoma cases that are at increased risk of being more aggressive and are suspected of malignant transformation. Furthermore, radiofrequency ablation has been used, but is typically most successful for small chondroblastoma lesions (approximately 1.5 cm). Treatment with radiofrequency ablation is highly dependent on size and location due to the increased risk of larger, weight-bearing lesions being at an increased risk for articular collapse and recurrence.

Overall, the success and method of treatment is highly dependent upon the location and size of the chondroblastoma.

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.

The infected tissue of the periapical cyst must be entirely removed, including the epithelium of the cyst wall; otherwise a relapse is likely to occur. Root canal treatment should be performed on the tooth if it is determined that previous therapy was unsuccessful. Removal of the necrotic pulp and the inflamed tissue as well as proper sealing of the canals and an appropriately fitting crown will allow the tooth to heal under uninfected conditions.

Surgical options for previously treated teeth that would not benefit from root canal therapy include cystectomy and cystostomy. This route of treatment is recommended upon discovery of the cyst after inadequate root canal treatment. A cystectomy is the removal of a cyst followed by mucosa and wound closure to reduce chances of cyst regeneration. This type of treatment is more ideal for small cysts.

A cystostomy is recommended for larger cysts that compromise important adjacent anatomy. The cyst is tamponaded to allow for the cyst contents to escape the bone. Over time, the cyst decreases in size and bone regenerates in the cavity space.

Marsupialization could also be performed, which involves suturing the edges of the gingiva surrounding the cyst to remain open. The cyst then drains its contents and heal without being prematurely closed. The end result is the same as the cystostomy, bone regeneration. For both a cystostomy and marsupialization, root resectioning may also be required in cases where root resorption has occurred.

Because newborns can breathe only through their nose, the main goal of postnatal treatment is to establish a proper airway. Primary surgical treatment of FND can already be performed at the age of 6 months, but most surgeons wait for the children to reach the age of 6 to 8 years. This decision is made because then the neurocranium and orbits have developed to 90% of their eventual form. Furthermore, the dental placement in the jaw has been finalized around this age.

When treatment is required, this is usually by surgical removal of the cyst. There are four ways in which cysts are managed:

- Enucleation - removal of the entire cyst

- Marsupialization - the creation of a window into the wall of a cyst, allowing the contents to be drained. The window is left open, and the lack of pressure within the cyst causes the lesion to shrink, as the surrounding bone starts to fill in again.

- Enucleation following marsupialization - Sometimes marsupialization is carried out as a single procedure, but usually it is followed by a second procedure to remove the cyst. This is particularly the case when cysts are very large and their removal would leave a significant surgical defect.

- Enucleation with curettage - this is removal of the cyst and some of the surrounding bone, which may contain some of the lining of the cyst.

Chemotherapy and radiotherapy are effective in some tumors (such as Ewing's sarcoma) but less so in others (such as chondrosarcoma).

There is a variety of chemotherapy treatment protocols for bone tumors. The protocol with the best reported survival in children and adults is an intra-arterial protocol where tumor response is tracked by serial arteriogram. When tumor response has reached >90% necrosis surgical intervention is planned.

Treatment ranges from simple enucleation of the cyst to curettage to resection. For example, small radicular cyst may resolved after successful endodontic ("root-canal") treatment. Because of high recurrence potential and aggressive behaviour, curettage is recommended for keratocyst. However, the conservative enucleation is the treatment of choice for most odontogenic cysts. The removed cyst must be evaluated by pathologist to confirm the diagnosis, and to rule out other neoplastic lesions with similar clinical or radiographic features (e.g., cystic or solid ameloblastoma, central mucoepidermoid carcinoma). There are cysts, e.g. buccal bifurcation cyst with self-resolation nature, in which close observation can be employed unless the cyst is infected and symptomatic.

Treatment is symptomatic, often addressing indicators associated with peripheral pulmonary artery stenosis. Laryngotracheal calcification resulting in dyspnea and forceful breathing can be treated with bronchodilators including the short and long-acting β2-agonists, and various anticholinergics. Prognosis is good, yet life expectancy depends on the severity and extent of diffuse pulmonary and arterial calcification.

Structural nasal deformities are corrected during or shortly after the facial bipartition surgery. In this procedure, bone grafts are used to reconstruct the nasal bridge. However, a second procedure is often needed after the development of the nose has been finalized (at the age of 14 years or even later).

Secondary rhinoplasty is based mainly on a nasal augmentation, since it has been proven better to add tissue to the nose than to remove tissue. This is caused by the minimal capacity of contraction of the nasal skin after surgery.

In rhinoplasty, the use of autografts (tissue from the same person as the surgery is performed on) is preferred. However, this is often made impossible by the relative damage done by previous surgery. In those cases, bone tissue from the skull or the ribs is used. However, this may give rise to serious complications such as fractures, resorption of the bone, or a flattened nasofacial angle.

To prevent these complications, an implant made out of alloplastic material could be considered. Implants take less surgery time, are limitlessly available and may have more favorable characteristics than autografts. However, possible risks are rejection, infection, migration of the implant, or unpredictable changes in the physical appearance in the long term.

At the age of skeletal maturity, orthognathic surgery may be needed because of the often hypoplastic maxilla. Skeletal maturity is usually reached around the age of 13 to 16. Orthognathic surgery engages in diagnosing and treating disorders of the face and teeth- and jaw position.

For low-risk stress fractures, rest is the best management option. The amount of recovery time varies greatly depending upon the location and severity of the fracture, and the body's healing response. Complete rest and a stirrup leg brace or walking boot are usually used for a period of four to eight weeks, although periods of rest of twelve weeks or more are not uncommon for more severe stress fractures. After this period, activities may be gradually resumed as long as the activities do not cause pain. While the bone may feel healed and not hurt during daily activity, the process of bone remodeling may take place for many months after the injury feels healed. Incidences of refracturing the bone are still a significant risk. Activities such as running or sports that place additional stress on the bone should only gradually be resumed. Rehabilitation usually includes muscle strength training to help dissipate the forces transmitted to the bones.

With severe stress fractures (see "prognosis"), surgery may be needed for proper healing. The procedure may involve pinning the fracture site, and rehabilitation can take up to six months.

Children younger than 6 have the best prognosis, since they have time for the dead bone to revascularize and remodel, with a good chance that the femoral head will recover and remain spherical after resolution of the disease. Children who have been diagnosed with Perthes' disease after the age of 10 are at a very high risk of developing osteoarthritis and coxa magna. When an LCP disease diagnosis occurs after age 8, a better outcome results with surgery rather than nonoperative treatments. Shape of femoral head at the time when Legg-Calve Perthes disease heals is the most important determinant of risk for degenerative arthritis; hence, the shape of femoral head and congruence of hip are most useful outcome measures.

There are many causes of toothache and its diagnosis is a specialist topic, meaning that attendance at a dentist is usually required. Since many cases of toothache are inflammatory in nature, over the counter non-steroidal anti-inflammatory drugs (NSAIDs) may help (unless contraindicated, such as with a peptic ulcer). Generally, NSAIDs are as effective as aspirin alone or in combination with codeine. However, simple analgesics may have little effect on some causes of toothache, and the severe pain can drive individuals to exceed the maximum dose. For example, when acetaminophen (paracetamol) is taken for toothache, an accidental overdose is more likely to occur when compared to people who are taking acetaminophen for other reasons. Another risk in persons with toothache is a painful chemical burn of the oral mucosa caused by holding a caustic substance such as aspirin tablets and toothache remedies containing eugenol (such as clove oil) against the gum. Although the logic of placing a tablet against the painful tooth is understandable, an aspirin tablet needs to be swallowed to have any pain-killing effect. Caustic toothache remedies require careful application to the tooth only, without coming into excessive contact with the soft tissues of the mouth.

For the dentist, the goal of treatment generally is to relieve the pain, and wherever possible to preserve or restore function. The treatment depends on the cause of the toothache, and frequently a clinical decision regarding the current state and long-term prognosis of the affected tooth, as well as the individual's wishes and ability to cope with dental treatment, will influence the treatment choice. Often, administration of an intra-oral local anesthetic such as lidocaine and epinephrine is indicated in order to carry out pain-free treatment. Treatment may range from simple advice, removal of dental decay with a dental drill and subsequent placement of a filling, to root canal treatment, tooth extraction, or debridement.

Giant osteoclasts can occur in some diseases, including Paget's disease of bone and bisphosphonate toxicity.
