[Diagnosis and treatment of frostbite].

Pathophysiology, clinical picture with grading and in some cases controversial possibilities of treatment are described. We report on our experience in treatment of 21 cases of frostbite on hands and feet. Widening by DSA of the diagnostic spectrum of late sequelae is emphasized.

[Should a single long finger be replanted?].

The indications for the replantation of single amputated digits are still widely discussed. According to our experience of 136 replanted single fingers in a period of six years and the results of an examination of 86 of these cases carried out subsequently, a large percentage of the patients is satisfied with the outcome of their operations. Therefore in general replantation of single fingers should not be rejected. In a doubtful case it would be advisable to transfer the patient to a hand- and microsurgery center.

[Thumb replacement by microsurgery].

Our experiences with 11 heterotopic finger replantations and 18 cases of free second toe transfer for thumb reconstruction are reported. The wrap-around flap technique (Morrison) is also described.

[Microsurgical anastomoses of nerves and arteries using absorbable sutures (author's transl)].

Anastomoses of the carotid artery and the sciatic nerve of the rat were performed by using the microsurgical technique and comparing the nonabsorbable suture material Ethilon and the absorbable Vicryl, both 0,2 metric. No suture insufficiency neither in sutured nerves nor in vessels could be observed. After 70 to 84 days the Vicryl sutures were completely absorbed. In particular nerve sutures using Vicryl proved to be superior to Ethilon, as the displacement of axons in the area of granuloma decreased with progressing absorption of the suture and the degeneration of the axons was less renewed.

[Microsurgical nerve and blood vessel sutures with resorbable suture material].

An experimental study of the behavior of the absorbable suture Polyglactin 910 (Vicryl) 0,2 metric in the tissue was performed. Microsurgical sutures of nerves and vessels (sciatic nerve and carotid artery) were performed and compared with a non-absorbable suture (Ethilon). The micromorphological studies included a period of 12 weeks after surgery. The absorbable suture showed equal mechanical qualities, with the advantage that the suture material and the tissue reaction disappeared after the 10th week, while the poor visualization of the absorbable suture under the operating microscope was a disadvantage.

[Microsurgical nerve and blood vessel sutures using a resorbable suture material].

Anastomosis of A. carotis and of N. ischiadicus of the rat were carried out by microsurgical technique in comparison to the nonabsorbable suture material Ethilon and the absorbable Vicryl, both 0,2 metric. There occurred no suture insufficiencies with either sutured nerves or vessels. After 70-84 days the Vicryl sutures were completely absorbed. In particular with nerve sutures Vicryl proved to be superior to Ethilon, as the displacement of axons in the area of granuloma decreased with progressing absorption of the suture and thus also resulting less renewed and thus also resulting less renewed degeneration of the axons.

[Late results after thumb replantation].

72 cases of thumb amputation and replantation were studied, 50% of which resulted from saw injuries and 20% from avulsions. 64 (88,9%) of the thumbs survived. The functional results in 52 available for review show that 95% achieved a good or satisfactory result. This demonstrates clearly that a thumb amputation is always an absolute indication for a replantation. In a multiple amputation case, where the thumb is destroyed or absent one should do a primary finger transfer. In such cases also we achieved similar good results.

[Bone healing in replantation surgery of the hand].

For the most part we use single axial Kirschner drill wires for the stabilization of fractured bones in the replantation surgery on the hand. The results of a re-examination of 102 patients with 176 replanted parts of the hand are reported and discussed.

[Finger replantation in children].

The possibility of replantation is discussed for children's amputation injuries. The use of this technique is also indicated for multiple amputations and severe crush injuries. More than half of the replanted fingers healed successfully. Since the existence of the Replantation centre of the Klinikum Rechts der Isar, over 600 operations of separated limbs were performed. The healing rate of totally and subtotally separated limbs of adults was 87%. The attempt was made to replant separated digits of 14 children, aged from 1 to 8 years, with microvascular anastomoses. The grade of injuries and the minimal size of anatomic structures demand a particularly high standard of the operative standard. Replantation was also indicated for badly squashed and contaminated limbs.
