[Juvenile osteochondrosis and osteonecrosis].

BACKGROUND

Juvenile osteonecrosis is an important topic in orthopedics. A wide variety of body regions of the growing patient are affected, predominantly during adolescence. All are characterized by a usually unknown aetiology as well as a stadium-like course. The main problem is a local osseous circulatory disorder, which causes osteonecrosis.

RISK FACTORS: Mechanical overloading due to increased body weight, axial misalignment, and sports activity is discussed as a risk factor. Healing depends on the localization and extent of the osseous necrosis.

DIAGNOSTICS: Diagnostically, radiologic imaging is used, in which the typical bony remodeling can be followed.

THERAPY: The therapeutic procedure depends on the affected region but is usually accompanied by a reduction of mechanical loading. If the clinical and radiological findings worsen, surgical treatment must be considered. The recognition and treatment of juvenile osteonecrosis is important and significantly influences the further development of the patient.
