[The concept of the surgical treatment of ectrodactyly in children].

The author presents his view on the problem of treatment of ectrodactyly on the basis of his experience with treatment of 159 children with this complex pathology. 1211 plastic and reconstructive operations were made on these patients. Results of the treatment were followed up during 14 years.

[Significance of vascular structure and regional hemodynamics in the surgical treatment of hand dysgenesis in children].

The analysis of 195 angiographies of 130 patients with different kind of had dysontogenesis has been made. The age of patients was between 1 and 15 years old. The author believes that the anomalous hand has a deficit of the blood supply.

[Brachydactyly of the hand].

The author has analyzed 54 patients aged from 9 months till 14 years with one of the types of congenital underdevelopment of fingers-brachydactyly. This form of the congenital pathology of the hand is concretized, the X-ray and clinical picture of brachydactyly is analyzed and more exact classification of this pathology is given. The state of blood supply, innervation and histological structure of the abnormal hand tissues are studied.

[Repair of posttraumatic hand defects in children].

The experience with the use of a method of distraction for reconstruction of 98 digits in 37 patients with amputation defects has been summarized. Lengthening of the digits by 3-7 cm was achieved. This permitted to improve considerably the function and cosmetic appearance of a damaged hand.

[Restorative treatment of blast injuries of the hand in children].

The experience of surgical treatment of children with the most grave hand injuries is presented. The authors consider that the restorative treatment is to begin from the moment of initial surgical processing of the explosive hand injuries. Three periods of treatment have been singled out.

[Functional treatment of uncomplicated extension transcondylar fractures of the humerus in children].

In the article is summarized experience of early functional treatment of children with extension trans-condyle fractures of humerus proposed by the authors. The proposed method allows to achieve complete restoration of the damaged elbow joint function in 40 +/- 2 days after the fracture reposition and to obtain excellent functional results with 85% of patients.

[Histological features of interdigital muscles in lengthening of underdeveloped fingers in children].

There has been carried out histologic examination of vermicular and interosseal muscles in case of underdevelopment of fingers before and after the restoration of their length by method of distraction in 45 children aged 4-14 years. There has been stated that in case of congenital finger underdevelopment the hand muscles are subjected to hypoplasia. However they are endowed with high ability of regeneration and restore their structure in response to distraction after adequate regenerative changes.

[Aplasia of the radius of the hand].

In the article is described the congenital pathology of the hand, characterized by the absence of one or several fingers with the corresponding metacarpal bones and bones of the wrist. There is given the clinical picture of 104 patients with the hand radius aplasia. There are singled out main forms of pathology, presented the data of the additional investigation methods (angiography, rheovasography, histologic structure of the affected hand tissues).

[Histologic characteristics of the tendons after lengthening of hypoplastic fingers in children].

A histologic study of the tendons of hypoplastic fingers before and after the restoration of their length by the method of distraction has been performed in 37 children aged 1 to 14 years. It has been established that in congenital defects of development of the hand the tendons of the hypoplastic fingers have an organotypical structure differing only in thinning of the facieles of ascending order. In the process of distraction of the rudiments of the hypoplastic fingers there is lengthening of the tendons with violation of the specialized structures.
