Transplantation of fresh-frozen menisci: an experimental study in dogs.

Transplantation of 25 fresh-frozen medial menisci was studied in 15 adult dogs. Before implantation, the allografts were deep-frozen and stored at -70 degrees C for 6 weeks to 18 months. The animals were killed 2 to 8 months postoperatively, and their knees and transplants were examined macroscopically and histologically.

[Fracture of a transfixed intramedullary nail in a patient with pseudoarthrosis of the femoral diaphysis].

This is a case report on a patient with a multiple femur's fracture where a transfixed intramedullar nailing of Grosse-Kempf type has been done. "The nail dynamization" was not carried out before the beginning of vertical loading. Seven months after the full vertical loading had begun, at a sudden torsian movement of the extremity, the nail had broken.

Allograft meniscus transplantation in the dog.

We studied transplantation of a fresh meniscus in 25 knees in 15 adult dogs. On 2 tables and with 2 surgical teams the medial menisci were explanted, exchanged and implanted into the opposite dog's knee. The animals were killed 4-12 months postoperatively, and the transplants were studied histologically.

[Revascularization of the forelimb in dogs].

Revascularization of the forearm was performed on six mature dogs of a different race. Arteria mediana was cut 2 cm above the fork of the arteria radialis and later sutured with a nonresorptive monofilament thread/Ethilonr/7-0 and 8-0 in diameter. The same process was repeated on the cefalica vein.

[Transplantation of the meniscus in dogs--preliminary report].

A preliminary investigation of the allogenic transplantation of the meniscus without the vascular bundle was carried out in 4 adult dogs with 8 knees. In one operation session on 2 dogs at 2 operative tables and with two operative teams an identical surgical procedure in general anaesthesia was done. A medial parapatellar incision of the knee was used, the medial capsule and the collateral ligament near its proximal insertion were severed.
