The Orthopedic Foundation for Animals in the United States will grade elbow X-rays of dogs intended for breeding.

In a recent comparative orthopedic study, a new bioscaffold having an embryonic-like structure has shown positive clinical outcomes in dogs with advanced, end stage osteoarthritis. The bioscaffold was implanted into intra-articular areas and reported up to 90-days of clinical improvement after a single implant. The bioscaffold has been shown to cause infiltrating cells to upregulate a variety of tissue repair factors including aggrecan, connective tissue growth factor, bone morphogenetic protein, transforming growth factors, and other tissue repair factors associated with osteoarthritis TR BioSurgical, LLC.

OCD also is found in animals, and is of particular concern in horses, as there may be a hereditary component in some horse breeds. Feeding for forced growth and selective breeding for increased size are also factors. OCD has also been studied in other animals—mainly dogs, especially the German Shepherd—where it is a common primary cause of elbow dysplasia in medium-large breeds.

In animals, OCD is considered a developmental and metabolic disorder related to cartilage growth and endochondral ossification. Osteochondritis itself signifies the disturbance of the usual growth process of cartilage, and OCD is the term used when this affects joint cartilage causing a fragment to become loose.

According to the Columbia Animal Hospital the frequency of affected animals is dogs, humans, pigs, horses, cattle, chickens, and turkeys, and in dogs the most commonly affected breeds include the German Shepherd, Golden and Labrador Retriever, Rottweiler, Great Dane, Bernese Mountain Dog, and Saint Bernard. Although any joint may be affected, those commonly affected by OCD in the dog are: shoulder (often bilaterally), elbow, knee and tarsus.

The problem develops in puppyhood although often subclinically, and there may be pain or stiffness, discomfort on extension, or other compensating characteristics. Diagnosis generally depends on X-rays, arthroscopy, or MRI scans. While cases of OCD of the stifle go undetected and heal spontaneously, others are exhibited in acute lameness. Surgery is recommended once the animal has been deemed lame.

Osteochondritis dissecans is difficult to diagnose clinically as the animal may only exhibit an unusual gait. Consequently, OCD may be masked by, or misdiagnosed as, other skeletal and joint conditions such as hip dysplasia.

OCD is a relatively rare disorder, with an estimated incidence of 15 to 30 cases per 100,000 persons per year. Widuchowski W "et al." found OCD to be the cause of articular cartilage defects in 2% of cases in a study of 25,124 knee arthroscopies. Although rare, OCD is noted as an important cause of joint pain in active adolescents. The juvenile form of the disease occurs in children with open growth plates, usually between the ages 5 and 15 years and occurs more commonly in males than females, with a ratio between 2:1 and 3:1. However, OCD has become more common among adolescent females as they become more active in sports. The adult form, which occurs in those who have reached skeletal maturity, is most commonly found in people 16 to 50 years old.

While OCD may affect any joint, the knee—specifically the medial femoral condyle in 75–85% of knee cases—tends to be the most commonly affected, and constitutes 75% of all cases. The elbow (specifically the capitulum of the humerus) is the second most affected joint with 6% of cases; the talar dome of the ankle represents 4% of cases. Less frequent locations include the patella, vertebrae, the femoral head, and the glenoid of the scapula.

The ultimate cause for these conditions is unknown, but the most commonly cited cause factors are rapid growth, heredity, trauma (or overuse), anatomic conformation, and dietary imbalances; however, only anatomic conformation and heredity are well supported by scientific literature. The way that the disease is initiated has been debated. Although failure of chondrocyte differentiation, formation of a fragile cartilage, failure of blood supply to the growth cartilage, and bone necrosis all have been proposed as the starting point in the pathogenesis, recent literature strongly supports failure of blood supply to growth cartilage as most likely.

Osteochondrosis is a family of orthopedic diseases of the joint that occur in children and adolescents and in rapidly growing animals, particularly pigs, horses, dogs, and broiler chickens. They are characterized by interruption of the blood supply of a bone, in particular to the epiphysis, followed by localized bony necrosis, and later, regrowth of the bone. This disorder is defined as a focal disturbance of endochondral ossification and is regarded as having a multifactorial cause, so no one thing accounts for all aspects of this disease.

Although the exact cause of Panner Disease is unknown, in recent research, it has been concluded that it may be associated with frequent throwing or other athletic activity. In the same article that talks about varying osteochondrosis diseases, it is pointed out that Panner Disease always involves alteration of the capitellum, which can be visualized by radiography. In another research article, the research team aimed to summarize the best available evidence for diagnosis and treatment for Panner Disease. In the article it was found that the most common symptoms that patients with Panner Disease present with are elbow stiffness and swelling, limited range of motion, and limited elbow extension. In alignment with the previously mentioned article, the team of researchers also concluded that Panner Disease involves irregularity of the capitellum, specifically that it appears flattened. Panner Disease often gets misdiagnosed as osteochondritis dissecans (OCD), and in this article they distinguish the difference between the two diseases are age difference and radiographic findings. In alignment with the two previously discussed articles, another article that reports on three case studies of Panner Disease, states that the primary treatment that is used for Panner Disease is rest and restriction from all physical and athletic activity that involves the use of the upper extremities; the activity is suggested to be ceased until the symptoms are relieved.

Life expectancy for individuals with hypochondroplasia is normal; the maximum height is about 147 cm or 4.8 ft.

Scheuermann's disease is self-limiting after growth is complete, meaning that it generally runs its course and never presents further complication. Typically, however, once the patient is fully grown, the bones will maintain the deformity. For this reason, there are many treatment methods and options available that aim to correct the kyphosis while the spine is still growing, and especially aim to prevent it from worsening.

While there is no explanation for what causes Scheuermann's Disease, there are ways to treat it. For decades there has been a lot of controversy surrounding treatment options. For less extreme cases, manual medicine, physical therapy and/or back braces can help reverse or stop the kyphosis before it does become severe. Because the disease is often benign, and because back surgery includes many risks, surgery is usually considered a last resort for patients. In severe or extreme cases, patients may be treated through an extensive surgical procedure in an effort to prevent the disease from worsening or harming the body.

In Germany, a standard treatment for both Scheuermann's disease and lumbar kyphosis is the Schroth method, a system of specialized physical therapy for scoliosis and related spinal deformities. The method has been shown to reduce pain and decrease kyphotic angle significantly during an inpatient treatment program.

In regards to treatment of hypochondroplasia usually takes the form of orthopedic surgery and physical therapy. Genetic counseling is advised for individuals and their families. Specifically in the case of spinal stenosis, one option is laminectomy.

Osteoporosis is due to causal factors like atrophy of disuse and gonadal deficiency. Hence osteoporosis is common in post menopausal women and in men above 50 yrs. Hypercorticism may also be causal factor, as osteoporosis may be seen as a feature of Cushing's syndrome.

Spinal fusion for kyphosis and scoliosis is an extremely invasive surgery. The risk of complications is estimated to be about 10%. Possible complications may be inflammation of the soft tissue or deep inflammatory processes, breathing impairments, bleeding and nerve injuries, or infection. As early as five years after surgery around 5% require reoperation and long-term issues remain unclear. Taking into account that some of the symptoms of the spinal deformity cannot be changed by surgical intervention, surgery remains a cosmetic indication, though the cosmetic effects of surgery are not necessarily stable.

The goal of treatment in Panner disease is to relieve pain. Treatment for Panner Disease is very minimal because in most children the bones repair their blood supply and rebuild themselves and this leads to the rebuilding of the growth plate and the capitellum returns to its normal shape. The period of rebuilding and regrowth varies from child to child and can last anywhere between weeks to several months. To relieve the pain, the child is restricted from participating in sports and activities until the elbow is healed and to also rest the affected elbow. Rest will allow for the pain to be relieved and return of full elbow movement. It may also be recommended for children to apply an icepack or heat to the elbow to alleviate pain and swelling. If the child has great difficulty bending and straightening the arm then physical therapy may also be recommend. Occasionally, it is recommended for children to use nonsteroidal anti-inflammatory drugs (NSAIDs) or acetaminophen to also reduce pain and swelling. For treatment, Panner Disease heals well in children with rest and restriction of physical activity and sports using the affected arm. The prognosis is also good with treatment and the affected capitellum is remodeled. Irregularities of the capitellum and surrounding elbow area can both be seen by radiograph and MRI. When treatment is effective the flattened and fragmented capitellum is completely remodeled and returns to its normal circular shape, and also the high intensity signal on a MRI T2 series disappears. These results indicate that the capitellum is completely remodeled and the child is able to return to normal physical and sports activities.

Metabolic bone disease is an umbrella term referring to abnormalities of bones caused by a broad spectrum of disorders.

Most commonly these disorders are caused by abnormalities of minerals such as calcium, phosphorus, magnesium or vitamin D leading to dramatic clinical disorders that are commonly reversible once the underlying defect has been treated. These disorders are to be differentiated from a larger group of genetic bone disorders where there is a defect in a specific signaling system or cell type that causes the bone disorder. There may be overlap. For example, genetic or hereditary hypophosphatemia may cause the metabolic bone disorder osteomalacia. Although there is currently no treatment for the genetic condition, replacement of phosphate often corrects or improves the metabolic bone disorder.

Osteochondritis is a painful type of osteochondrosis where the cartilage or bone in a joint is inflamed.

It often refers to osteochondritis dissecans (sometimes spelt "dessecans", and abbreviated OCD). The term "dissecans" refers to the "creation of a flap of cartilage that further dissects away from its underlying subchondral attachments (dissecans)".

The other recognized types of osteochondritis are osteochondritis deformans juvenilis (osteochondritis of the capitular head of the epiphysis of the femur) and osteochondritis deformans juvenilis dorsi (osteochondrosis of the spinal vertebrae, also known as Scheuermann's disease).

Osteochondritis, and especially osteochondritis dissecans, can manifest in animals as a primary cause of elbow dysplasia, a chronic condition in some species and breeds.

In terms of epidemiology, Jackson–Weiss syndrome is a rare genetic disorder; the overall contribution of FGFR mutation to the condition is not clear.

A diagnosis of kyphosis is generally made through observation and measurement. Idiopathic causes, such as vertebral wedging or other abnormalities, can be confirmed through X-ray. Osteoporosis, a potential cause of kyphosis, can be confirmed with a bone density scan. Postural thoracic kyphosis can often be treated with posture reeducation and focused strengthening exercises. Idiopathic thoracic kyphosis due to vertebral wedging, fractures, or vertebral abnormalities is more difficult to manage, since assuming a correct posture may not be possible with structural changes in the vertebrae. Children who have not completed their growth may show long-lasting improvements with bracing. Exercises may be prescribed to alleviate discomfort associated with overstretched back muscles. A variety of gravity-assisted positions or gentle traction can minimize pain associated with nerve root impingement. Surgery may be recommended for severe idiopathic kyphosis.

Body braces showed benefit in a randomised controlled trial.

The Milwaukee brace is one particular body brace that is often used to treat kyphosis in the US. Modern CAD/CAM braces are used in Europe to treat different types of kyphosis. These are much easier to wear and have better in-brace corrections than reported for the Milwaukee brace. Since there are different curve patterns (thoracic, thoracolumbar and lumbar), different types of brace are in use, with different advantages and disadvantages.

There is no causative / curative therapy. Symptomatic medical treatments are focussing on symptoms caused by orthopaedic, dental or cardiac problems. Regarding perioperative / anesthesiological management, recommendations for medical professionals are published at OrphanAnesthesia.

Treatment for Jackson–Weiss syndrome can be done through surgery for some facial features and feet. Secondary complications such as hydrocephalus or cognitive impairment, can be averted via prompt surgery.

Ellis–van Creveld Syndrome (also called "chondroectodermal dysplasia" or "mesoectodermal dysplasia" but see 'Nomenclature' section below) is a rare genetic disorder of the skeletal dysplasia type.

Currently there are no open research studies for otodental syndrome. Due to the rarity of this disease, current research is very limited.

The most recent research has involved case studies of the affected individuals and/or families, all of which show the specific phenotypic symptoms of otodental syndrome. Investigations on the effects of FGF3 and FADD have also been performed. These studies have shown successes in supporting previous studies that mutations to FGF3 and neighboring genes may cause the associated phenotypic abnormalities. According to recent studies involving zebrafish embryos, there is also support in that the FADD gene contributed to ocular coloboma symptoms as well.

Future research studies are required in order to better grasp the specific relationship between the gene involved and its effect on various tissues and organs such as teeth, eyes, and ear. Little is known and there is still much to be determined.

Cartilage–hair hypoplasia (CHH), also known as McKusick type metaphyseal chondrodysplasia, is a rare genetic disorder. It is a highly pleiotropic disorder that clinically manifests by form of short-limbed dwarfism due to skeletal dysplasia, variable level of immunodeficiency and predisposition to malignancies in some cases. It was first reported in 1965 by McKusick et al. Actor Verne Troyer is affected with this form of dwarfism, as was actor Billy Barty, who was renowned for saying "The name of my condition is Cartilage Hair Syndrome Hypoplasia, but you can just call me Billy."

There is currently no specified treatment for individuals suffering from otodental syndrome. Considering that there are many possible genetic and phenotypic associations with the condition, treatment is provided based on each individual circumstance. It is recommended that those affected seek ear, nose & throat specialists, dental health specialists, and facial oral health specialists immediately; in order to determine potential treatment options.

Common treatment methods given are:

- Dental treatment/management – which can be complex, interdisciplinary and requires a regular follow up. Tooth extraction(s)and if needed, medications may be administered for pain, anxiety, and anti-inflammation. The affected individual is usually placed on a strict and preventative dental regiment in order to maintain appropriate oral hygiene and health.

- Endodontic treatment – individuals consult with an endodontist to analyze the individuals dental pulp. Typically endodontic treatment proves to be difficult due to duplicated pulp canals within the affected teeth. There may be a need for multiple extractions as well. Dental prosthesis and/or dental implants may be necessary for individuals that lack proper oral function, appearance, and comfort.

- Orthodontic treatment – given the predicament of the size and location of the affected oral area, molars and canines, orthodontic treatment is generally required in order treat any problems associated with the individuals bite pattern and tooth appearance.

- Hearing aids – in some cases affected individuals will suffer from hearing imparities and it may be necessary for hearing aid use.

The functional prognosis is mostly good with those that suffer from otodental syndrome. Appropriate dental treatment, hearing aids, and visitation to necessary specialists are recommended. Quality of life may be affected by psychological and functional aspects. It is also recommended that genetic counseling be given to families that have or may have this condition.

Patients with CHH usually suffer from cellular immunodeficiency. In the study of 108 Finnish patients with CHH there was detected mild to moderate form of lymphopenia, decreased delayed type of hypersensitivity and impaired responses to phytohaemagglutinin. This leads to susceptibility to and, in some more severe cases, mortality from infections early in childhood. There has also been detected combined immunodeficiency in some patients

Patients with CHH often have increased predispositions to malignancies.
