[Sonography of the locomotor system. Indications, possibilities, limits and perspectives].

Based on 10 years' experience with sonography in the locomotor system and having participated in the education of about 2,000 colleagues to teach them how to use ultrasonography, the technical and methodological limitations of sonography are reported in the field of muscles and tendons, the spine, shoulder, knee and hip joints, and tumors. The sonographic standards in orthopedics that are performable but not relevant in treatment are discussed, and the nonsense is also pointed out. An attempt is made to make a critical statement about the potentials of orthopedic sonography today.
