The aim of the investigation is to increase the efficiency of treatment of osteoarthrosis deformans of foot and ankle joints by developing and applying new hi-tech methods of treatment - individual replacement of the foot bones and joints. Materiales and methods. 39 patients with the specified pathology were surveyed. Standard total ankle replacement was performed in two of them (STAR, W. Link), 16 patients underwent the first MTP joint replacement with Total toe system. In five cases with the 1st MTPJ arthrosis there was observed total, subtotal and polylocal aseptic necrosis of the head of the first metatarsal bone. 10 patients had a similar picture of damage of the talus due to trauma. For these patients individual artificial implants of the talus and endoprostheses of the first MTPJ were developed. Modern techniques (CT, MRT) were used to early radiodiagnosis of posttraumatic talus damage. Results and Discussion. There were developed new methods of surgical treatment of such consequences of trauma of the talus as total, subtotal and polylocal aseptic necrosis - individual total replacement of the talus by original patented technique and replacement of the first MTP joint in cases of severe aseptic necrosis of the 1st metatarsal bone's head with the implant with the long stem (when standard joint replacement is noneffective). Pre-production models of implants and tools were made, and technical tests of designs were carried out. Source

There have been presented clinical presentation of traumatic brain compression, and considered modern diagnostic and surgical approaches. Five variants of surgical approaches depending on the dynamics of clinical presentation, and the findings of instrumental investigations (CT, MRT) have been suggested. Indications and contradictions to conservative treatment of brain compression have been stated. There has been emphasized the aspects of the problem unsolved and under debate. Source

The aim of the study is to develop a method to determine a projection angle of frontal inclination of pelvic component of an endoprosthesis. Materials and Methods. There has been made an experimental study using roentgenometry. Acetabular components of endoprostheses of different manufacturers have been tested. Results. A new X-ray angle metric index of frontal inclination of pelvic component of endoprostheses of different modifications is suggested. It enables to determine a frontal inclination angle of pelvic component of an endoprosthesis. The index corresponds to a true one and does not depend on design features of an endoprosthesis. Source

There have been shown the treatment possibilities of patients with post-burn and post-traumatic cicatricial deformity and defects of various localizations using the method of expander dermatension. The effectiveness of a new way of a dosage dermatension management in a constant mode by liquid pumping into a ballon-expander through infusomat (Patent No.2271157) has been studied. An optimal solution administration rate for different expanders has been selected. There has been described the way of objective control of soft tissue condition during distraction using thermovision studies (Patent No.2306847). The use of the techniques suggested enables to reduce the number of complication on dermatension stage and reduce the period of in-patient treatment by 1.5-2 times. Source

Background/purpose: The present study aimed to investigate the influence of topical corticosteroid therapy and tacrolimus on morphological indices of different skin phototypes and to optimize topical therapy using the OCT technique. Methods: Twenty healthy volunteers aging from 20 to 30 (14 men and 6 women) took part in the study: 10 persons with skin phototype I, II and 10 persons with skin phototype V, VI. Morphological state of the skin was assessed before and during application of topical steroids of different strength and calciumneurin inhibitors for 49 days. Morphological state was studied in vivo using the optical coherence tomograph. Results: Morphological manifestations of skin atrophy with the use of clobetasol propionate appear earlier than with the use of hydrocortisone 17-butyrate; this process was faster in representatives of groups V, VI. Epidermal thinning in the zone of tacrolimus application was not recorded in any phototype. Conclusion: Recording of early preclinical signs of epidermis thinning in the course of OCT follow-up may be an indication for changing the corticosteroid therapy by calciumneurin inhibitors, which will permit to individualize the therapy, to increase its efficacy, and to minimize the possibility of complications in each particular case. © 2013 John Wiley & Sons A/S.
