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 can be caused by rapid growth, high-energy diet, genetic factors, trauma, and hormone imbalances.

Etiology

The exact cause of osteochondrosis is unknown. However, it is believed to be multifactorial, involving genetic, nutritional, and biomechanical factors. Rapid growth and high-energy diet might contribute to the development of the disease in some cases. Trauma to the joint, such as a fracture or dislocation, can also lead to osteochondrosis. Hormonal imbalances, particularly of growth hormone and thyroid hormones, have been implicated as well.

Pathophysiology

In osteochondrosis, the normal process of bone growth and maturation is disrupted. This leads to the development of areas of necrosis (dead bone) in the epiphysis. These areas of necrosis can cause pain and loss of function of the affected joint. Over time, the necrotic bone is resorbed and replaced by new bone. However, this new bone is often weaker and more prone to fracture than normal bone.

Clinical Presentation

The clinical presentation of osteochondrosis can vary depending on the affected joint. Common symptoms include pain, swelling, and limited range of motion of the affected joint. In some cases, a limp or abnormal gait may be observed. The onset of symptoms is usually gradual, and they may worsen with activity.

Diagnosis

Diagnosis of osteochondrosis is typically made based on the patient's history, physical examination, and imaging studies. X-ray is the most commonly used imaging modality, but MRI and CT scan can also be used to confirm the diagnosis and assess the extent of the disease.

Treatment

Treatment of osteochondrosis is primarily conservative, focusing on pain management and maintaining function of the affected joint. This may include rest, physical therapy, and non-steroidal anti-inflammatory drugs (NSAIDs). In severe cases, surgery may be required to remove the necrotic bone and stimulate new bone growth.

Prognosis

The prognosis for osteochondrosis is generally good, with most patients achieving a full recovery with appropriate treatment. However, some patients may experience long-term complications, such as osteoarthritis, if the disease is not properly managed.
