Nielsen Congenital Dystrophy

Nielsen congenital dystrophy (also known as dystrophia brevicollis congenita) is a rare congenital disease characterized by abnormal development of the cervical vertebrae. This leads to shortening of the neck and limitation of its mobility.

The disease was first described in 1950 by Danish radiologist Jens Nielsen, after whom it was named. The cause of Nielsen dystrophy is not completely clear, but is presumably associated with disturbances in the intrauterine development of the cervical spine.

The main symptoms are a short neck, low hairline at the back of the head, limited mobility and neck pain. There may be problems with breathing, swallowing, and poor posture.

Diagnosis is based on analysis of neck X-rays, CT and MRI. Treatment is mainly symptomatic and includes physiotherapy, exercise therapy, and sometimes surgery. The prognosis depends on the degree of damage to the cervical vertebrae. With timely diagnosis and treatment, patients' quality of life can be normal.



Nielsen congenital dystrophy (synonyms: congenital short-beak syndrome, congenital short-beak disease, congenital short-beak syndrome) is a hereditary disease of birds, characterized by a shortening of the beak and skull, as well as impaired bone growth.

Congenital dystrophy was first described in 1926 by the Danish veterinarian Nielsen, who called it short-beak syndrome. In the 1930s, other scientists discovered that short beak syndrome is caused by mutations in a gene encoding a protein called collagen X. However, the exact cause of the disease is still unknown.

Congenital dystrophy can appear in different forms, but the most common is the short-beaked form, in which the beak and skull become short and thin. Birds with this form of the disease may have breathing problems, as well as impaired bone growth and the development of various diseases such as arthritis and osteoporosis.

Treatment of congenital dystrophy can be difficult because the mutations that cause the disease can be very complex and often cannot be corrected. However, in some cases, the use of special medications that help improve bone growth and prevent the development of complications may be effective.

It is important to note that congenital dystrophy is not a contagious disease and does not pose a threat to human health. However, if you notice signs of this disease in your bird, it is recommended that you contact your veterinarian for diagnosis and treatment.
