[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.

Long-term follow-up results of 97 finger replantations.

From a total number of 664 finger replantations (DII-DV) we were able to carry out a follow-up of 97 postoperative cases using the follo-wing assessment criteria: mobility, sensitivity, type of amputation, mechanism of injury, level and extent of amputation. Subjective criteria were also taken into account. Using the results of the study we have been able to formulate an evaluation as to the absolute indication for operation of fingers DII-DV.

Replantation of the hallux by microsurgical techniques.

In this report three cases of successful hallux replantation are presented. The indications for this type or surgery are discussed on the basis of the functional results of these replantations. In our opinion, corrective surgery is indicated in all cases of traumatic hallux and/or multiple-toe amputations.

[International definitions in the field of replantation surgery and possibilities of an evaluation system of the functional results].

Based on the work of the Replantation Committee of the International Society of Reconstructive Microsurgery, general definitions in the field of replantation surgery are outlined. Specially the terms total and subtotal amputations in contrast to the term of revascularisation are clearly separated. In the other part of the paper general ideas are discussed about the different aspects for the judgement of the late functional results. It is recommended that an assessment of how the patient can use his replanted parts in his profession and daily life should receive particular emphasis.

[Reimplantation of peripheral parts of the extremities. 808 cases and functional results].

The Authors present 808 replantations by microsurgery in patients aged between 16 months and 70 years. The functional results were controlled in 369 cases after 10 to 20 months. The less satisfactory function was found in patients over 50 years and following combined injuries of the hand. The replantation of the thumb achieved the best results. The Authors point out that, despite a poor prognosis, some replantations should still be attempted because every case needs to be evaluated individually.

[The neurovascular forearm island flap].

We describe a neurovascular island flap of forearm skin based on the radial artery at the wrist level with reversed arterial blood flow. The flap may cover almost any skin and soft tissue defect of the hand. The flap is drained via venous anastomosis between one of the forearm veins and a suitable vein of the hand. Sensation is provided through a microneural anastomosis of one of the sensitive nerves of the forearm to a corresponding nerve of the hand.

[Thumb replacement by transplantation of the 2d toe].

After traumatic loss, the thumb can now be replaced by transfer of the toe due to the development of microvascular techniques. Because of the better aesthetic and functional result in the donor foot we prefer the second toe to the big toe. By including a part of the second metatarsal bone the length of the second toe transplants can be adjusted appropriately. In this report the operative technique and the result of eight of such procedures with seven successes is described.

[Microsurgery: organization and indication in the Federal Republic of Germany].

Since 1960's the new technique of microsurgery of the nerves was introduced in Germany at Departments of Plastic Surgery, Handsurgery and Neurosurgery. Since 1974 the technique of microvascular surgery was used in different places. In March 1975 the first free flap transfer was performed at our clinic in Munich. In the same year 24 h reimplantation services were established in Hamburg and Munich. In connection with training of other colleagues and information of the population we could perform up to 31 march 1980 703 replantations at the hand with a survival rate of 78.5%. Through education by annual instructional courses and fellowships at our clinic further replantation services were established in Germany. A general request showed that up to the middle of 1979 2742 micro- and 381 macro-replantations were performed in Germany. The places where replantations are done should be classified in 1. replantation centres (at present 9 in FRG), 2. replantation services (at present 4 in FRG), 3. places with microvascular experiences (at further 4 places in FRG). The training program for a member of a replantation team should include: 1. general surgery, traumatology, 2. plastic surgery, 3. hand surgery, 4. microsurgery. Beside the replantation also the clinical application of free tissue transplantation is increasingly used at our clinic and other places in Germany.

[Autologous vein grafts as artery replacement in microsurgery. An experimental study of micro- and macromorphologic changes 3 weeks to 12 months postoperatively].

In 45 rabbits we interposed autologous vein grafts of different length in equivalent defects of the femoral artery. After fixed intervals of six weeks to 12 months functional, histological and angiographic studies were done. Long grafts showed the same thrombus rate as short ones. The histological findings showed a marked thickening of the vessel wall with a maximum between six to eight weeks after operation. After this period this thickening was reduced but was after 12 months still noticeable. The angiography showed no signs of stenosis or narrowing of the lumen. Occasionally we saw bone formation or incrustation which might be induced by intima lesions.

Definitions and classifications in replantation surgery.

Attempts have been made internationally to introduce clear definitions and classifications in the new field of replantation surgery. A special Committee of the International Society of Reconstructive Microsurgery has developed and suggested clear definitions in this new field and has recommended an international replantation sheet. The next step will be to define criteria to assess the late functional results of such replantations.

[Primary transpositions of fingers, results (author's transl)].

12 cases of finger transposition during replantation using microvascular techniques are reported, all of which were performed in the Department of Plastic and Reconstructive Surgery, Klinikum Rechts der Isar der Technischen Universität München (Head of Department: Prof. Dr. med. Ursula Schmidt-Tintemann). In multiple injuries of the hand, it is sometimes necessary to reconstruct fingers depending on their functional importance, when it is not possible to make a precise anatomical reconstruction owing to the destruction of the various amputated parts. The functional results following finger transposition are comparable to the results following 500 finger replantations in our hospital.
