[Classification of total and subtotal amputations].

Up to now the succes rates in replantation surgery which are reported in the literature do not include the functional results. To compare the final functional results it is necessary to have a common international classification of what is a complete amputation and what is a incomplete one. It is then important to compare only similar subtotal amputations. In this paper we suggest a definition and classification of amputations in the upper extremity in the following way: type I....bone type II....extensor tendons type III....flexor tendons type IV....palmar digital nerves type V....skin A subtotal amputation will intakt flexor and extensor tendons as well as palmar nerves should be classified as "type II, III. IV".

[Complications in the replantation of amputated digits].

The reason for thrombosis in replantation is very often the injured intima of the vessel ends. The vessel ends should be excised until absolutely normal tissue is reached. In many cases of oblique cutting, avulsion or crushing it is then difficult or impossible to approximate the ends and venous grafts are employed to avoid undue skeletal shortening.

[Successful re-implantation of the metacarpus (author's transl)].

Two cases of subtotal traumatic metacarpal amputation in young people are described. Re-implantation with the help of microvascular surgical techniques was successful. In one case in which vascular connections to two long fingers were still present, the advantages of reconstruction of important vessels are pointed out, not only for re-implantation itself, but also as prophylaxis against circulatory disorders.

Replantation surgery.

From 1975 to 1988, replantation operations of fingers or hands were performed in 2,040 patients at the Division of Plastic and Reconstructive Surgery, Technical University Munich, Germany. The meticulous repair of blood vessels is still the most important step for a successful replantation. The liberal use of vein grafts very often makes replantations possible even in avulsion and crush injuries. The best functional results are achieved in replantations of distal finger parts, because an intact proximal interphalangeal joint and tendon apparatus guarantees almost a full range of motion. Age alone is not an exclusionary factor for replantation. Even 70 or 80 year old patients can achieve a satisfying functional result after replantation. Replantation as a matter of course is indicated in every amputation. Nevertheless, the extent of tissue damage, patient age and general health condition as well as the patient's wishes regarding a replantation have to be considered before performing a replantation. In addition, only continuous, long-term physical therapy be specialized physical therapists and the continuous postoperative attention of the surgeon ensure a satisfying result.

PVP breast implants after two years: initial results of a prospective study.

A prospective study of a new mammary prosthesis with PVP-based gel as filling material was carried out. Scheduled follow-ups were planned at 3, 6, 12, and 24 months post-implantation to assess all complications, Baker scores, and the patient's, and the physician's global assessment of each implant. PVP-filled implants were used in 95 breasts for augmentation (60%) or reconstruction (40%). Sixty-nine percent of all patients underwent a primary procedure, 19% had a history of severe capsular fibrosis. During follow-up, a hematoma was observed in 2% and a seroma in 5%. Leakage occurred in 3% (one iatrogenic and two cases of unknown reason), a Baker 3 in 6% (12 months). No volume increase of the implants occurred. The probability that a patient would be complication-free at 24 months was 0.86. Physician's and patient's satisfaction rating after 12 months remained high without any time effect (physician very good/good 63%, patient 75%). According to our current experiences, the PVP-filled implants are a remarkable alternative with an improved viscosity and enhanced x-ray transmission, compared to saline filled implants.

Morbidity of the groin flap transfer: are we getting something for nothing?

The morbidity of pedicled groin flap transfer for upper extremity soft tissue reconstruction was investigated in 24 patients. The problems of the transferred flaps and of the donor site, and associated illness after the operation, are reported. The morbidity of groin flaps should be considered carefully, especially if transfer is planned in older patients.

Microvascular anastomosis by invagination: an experimental study.

A technique of end anastomosis of microvessels of equal or unequal diameter, requiring only two sutures is described. In the present investigation we used the common carotid artery and the femoral vein of 37 white rats. The adventitia of the proximal part of the anastomosed artery was subsequently prepared and removed. However, in case of vein anastomosis, the adventitia of the distal part was removed. Following this washing with saline solution was done. 10-0 Nylon monofil sutures, were used which were placed at 180 degrees. The anastomosis was completed by ligation in such a way that one end was invaginated into the other and was fixed firmly. Five months later the anastomoses were examined after careful preparation under the surgical microscope and photographed. A SEM examination was then done in half of them and photos were taken at 24X, 80X, 1,200x magnification. The remaining tissue was examined histologically. The findings after surgical microscope SEM and histological examination are described.

Salvage operations for complication following replantation and free tissue transfer.

Venous and arterial thrombus formation is the typical complication of microvascular surgery. Treatment is based on reoperation (thrombectomy), the administration of heparin, low moleecular weight dextran and platelet antisludge (dipyridamol and acetylsalicylic acid). As the reoperation must be performed promptly, careful postoperative monitoring of the transplant is required.
