[Computed tomographic studies of the central nervous system in small animals]. / Computertomographische Untersuchungen des Zentralnervensystems bei Kleintieren.

With computed tomography in 44 small animals some well defined anatomical structures and pathological processes of the central nervous system are described. Computed tomography is not only necessary for the diagnosis of tumors; malformations, inflammatory, degenerative and vascular diseases and traumas are also visible.

[Results of magnetic resonance and computerized tomography studies of augmentation plastic surgery of the anterior cruciate ligament using carbon fibers. II]. / Ergebnisse der magnetresonanz- und computertomographischen Untersuchung von Augmentations-plastiken am vorderen Kreuzband mit Kohlestoffasern. Teil II.

19 patients out of those described in part I were examined by MRI and CT. We quote MRI as an excellent new mean of imaging without exposure to ionising radiation which renders sufficient information about the internal knee-structures without surgical invasion. The signal density for the neoligament as well intraarticular as in the "over the top"-position gives evidence for the ingrowth of mesenchymal structures. The MRI diagnosis was proved by histological examination in 2 cases. Very good correspondence between clinic examination and the CT-images could be found. On top of that the tibial drilling holes could be shown in an excellent way. The CT-scan is a fine instrument to judge the postoperative state of the anterior cruciate ligament. The density measurement inside and outside the bone gives evidence for mesenchymal growth inside the carbon fibre structure and the existence of a new natural ligament.

[Total ulnar nerve paralysis in epiphysiolysis of the radius]. / Vollständige Ulnarislähmung bei Epiphysenlösung der Speiche.

Closed epiphysiolysis of the distal radius was followed by a complete sensomotor paralysis of the ulnar nerve revealed on removing the cast. The cause of paralysis was entrapment of the nerve and flexor carpi ulnaris in the fracture. After release of the incarceration and microsurgical extraneural and intraneural neurolysis very good rehabilitation of nervous function resulted. To exclude nerve injury the importance of exact detailed examination of recently injured persons is re-emphasized.
