[The use of medialis pedis flap for the plastic surgery of its injuries].

Complex topological investigation of 19 lower extremities of 10 nonfixed cadavers was conducted to substantiate the isolation possibilities and the variants of application of the foot insular medial flap. Fascio-cutaneous transplant was isolated on the inner foot side in the region of its nonbearing surface. Transposition of the flap on the proximal vascular-nervous pedicle was conducted into the heel region or on the distal vascular pedicle-into the anterior parts of foot with the microneuroraphy of the nerve sensitivity. Transplantation of such a tissue complex permitted to restore the adequate sensitivity and a full value cutaneous cover in the foot region.

Vascularized megaflaps.

In the early 1980s Japanese surgeons introduced very long free flaps based on two vascular pedicles from the thoracodorsal and groin territories. Such flaps, vascularized through two pedicles, may be called megaflaps. One or both bundles may be anastomosed as necessary to vascularize the flap. Anatomical studies and clinical experience point to new donor sites for such megaflaps.

A new classification of vascularized flaps in plastic and reconstructive surgery.

Advances during the last 15 years in microsurgical technique and in our understanding of vascular anatomy have led to the development of two new branches of plastic and reconstructive surgery. The first is the transfer of free composite flaps with microvascular anastomoses. The second is transposition of island flaps solely on a proximal or distal vascular bundle. Both types of operations require an adequate vascular pedicle to provide sufficient blood circulation for flap viability and survival in the recipient site.

[Areas of safe use of bone nails on the forearm].

On the basis of the data of topography-anatomical study, carried out at 30 upper extremities, are proposed zones and directions of safe application of wires of the compression-distraction apparatus at 4 forearm levels, developed with allowance made for individual differences in structure and topography of vessels and nerves as well as functional position of the segment. An experimental examination (30 extremities) and clinical approval (30 patients) of the proposed zones and directions have confirmed the practical use of the obtained data that allows to recommend them to be widely introduced into the clinical practice.

[The anatomicophysiological characteristics of the forearm as a donor site for the formation of tissue complexes on vascular pedicles].

Based upon results of the complex topographical anatomical research fulfilled on 68 upper extremities the forearm area is considered as a single donor zone for the formation of composite cutaneous flaps on the vascular pedicle good for both microsurgical autotransplantation and replacement in the form of islands on the proximal and distal vascular pedicles. Individual differences in the structure and topography of vascular-nervous formations of the forearm are presented as well as a rational technique of the formation of tissue flaps developed with special reference to them.

[Possibilities of reconstruction of the fingers in relation to individual differences in their topographic-anatomic structure].

On the basis of the results of topographic and anatomical investigation carried out at 44 hands of cadavers are discussed the possibilities of restoration of the first finger by means of movement of damaged fingers on the neurovascular limb. The fundamental methods of surgical technique, developed with regard to the structure of neurovascular formations of the hand and individual variability of their topography, are expounded.

[Vascularized tissue complexes from the region of the radial artery in plastic surgery of the arm].

Based upon results of topographo-anatomical research and personal experiences with transplantation of 91 tissue complexes on radial vascular bundle the authors made an attempt to systematize the available data concerning this source of tissues. The substantiation of using the tissue complexes consisting of several fascio-cutaneous (fascio-cutaneous and muscular) flaps at different levels of the vascular pedicle as well as superlong deltoid-radial flap on two vascular pedicles are first given.

[Comparative characteristics of the forearm and crus as donor sites for obtaining composite skin flaps on vascular pedicles].

The ++topographo-anatomical investigations on 67 forearms and 58 crura permitted to establish the possibility for formation of the free similar types of island composite cutaneous flaps on the large vascular bundles. On the crus, the possibility to elevate two more types of the island cutaneous flaps without transection of the major vessels is substantiated. The variants of microsurgical autotransplantation and trasplantation+ of the composite cutaneous flaps of the forearm and crus on the vascular pedicles are discussed.

[New principles in classifying vascularized tissue complexes used in plastic and reconstructive surgery].

Based on their personal experience of transplantation of 152 free and 367 non-free++ blood-supplied tissue complexes the authors propose to divide them into three main groups in relation to their specific formation and transplantation: mono-, poly- and megacomplexes of tissue (flaps). Distinctions of these three groups of tissue complexes, their general properties as well as indications for their application are discussed.

[Donor tissue source in plastic surgery of the hand].

From topographic and anatomical examination of 32 upper limbs the authors proved that an island skin-fascia graft supplied with blood by the septocutaneous branches of the posterior interosseous vascular bundle can be formed on the posterior aspect of the forearm. Such a graft on a peripheral vascular pedicle was transplanted in 6 patients with defects in the integumentary tissues of the hand; it healed completely in 4 cases, peripheral necrosis occurred in 2 cases but did not affect the end result. The use of means of optic magnification and prevention of compression of the vascular pedicle in the postoperative period ensure successful transplantation of the graft.

[Islet flaps from the forearm in plastic surgery of the hand].

An analysis of islet flaps of the forearm used in the performing of complex reconstructive operations on the hand in 37 patients is presented. A substantial shortcoming of transplantation of the radial and elbow flaps is a possible development of disturbance of blood circulation in the hand tissues which can require emergent plasty of the transected artery. In transplantation of the posterior flap of the forearm the blood circulation in the hand tissues was not disturbed.
