Treatment of equinocavovarus deformity in adults with the use of a hinged distraction++ apparatus.

We evaluated the results following the use of the Volkov-Oganesyan-Povarov hinged distraction apparatus to correct equinocavovarus deformity of the foot in sixty-five adults (eighty-three feet). The deformity was secondary to ischemic and neuropathic changes after trauma to the foot and ankle, poliomyelitis, Charcot-Marie-Tooth disease, or untreated clubfoot. The deformity often was associated with severe neurotrophic changes, extensive scarring of the skin, callosities, or osteomyelitis of the foot, all of which usually preclude operative reconstruction.

[Characteristics of foot blood supply in rigidity of the great toe].

By means of angiography, made in 20 patients with rigidity of the first toes due to osteoarthrosis, there have been revealed chronic deficiency of blood circulation in the foot tissues, especially in its antero-internal section. Blood circulation deficiency is due either to the congenital anomaly of the foot vessels or to the consequences of their traumatic injuries. Blood supply deficiency results in degenerative-dystrophic changes of the first metatarsophalangeal articulations with development of their rigidity, aggravated by post-ischemic contracture of the foot muscles.

Talipes equinocavovarus deformities corrected with the aid of a hinged-distraction apparatus.

In 56 patients (70 feet) with talipes equinocavovarus, various components of deformity were surgically corrected in multiple stages with the aid of a hinged-distraction apparatus and concurrent training and rehabilitation of motion in the ankle joint. Good results were obtained in 53 feet, satisfactory results in 13 feet, and unsatisfactory results in four feet. The complications brought on by apparatus-assisted therapy of talipes equinocavovarus deformities require additional treatment but do not depreciate the method.

[Treatment of equino-excavato-varus deformity of the feet in adults using a hinge-distraction apparatus].

The treatment of severe aggravated forms of equino-excavato-varus deformation of the feet of various etiology is rather difficult because the resections performed to eliminate the deformation require the removal of large quantities of the bone tissue and are traumatic, and when accompanied by neurotrophic disturbances they are usually contraindicated. At the Central Institute of Traumatology and Orthopaedics 65 patients with acutely pronounced feet deformations have been treated with Volkov-Organesian-Povarov distraction apparatuses. In 34 patients the deformation was accompanied by various neurotrophic disturbances.
