The Concept of Treatment for Surgical Infection in the Hindfoot.

Background: Chronic osteomyelitis of the calcaneus (OC) and open infected calcaneal fractures, especially when complicated by infected soft tissue defects, present significant surgical challenges. Accepted recommendations for the surgical treatment of this pathology are yet to be established.

Methods: Drawing from our experience and the consensus among experts, we have developed a concept for selecting optimal, well-known surgical approaches based on the specific pathologic presentation.

New Method of Tibio-calcaneal-Navicular Arthrodesis After Talectomy.

Background: After astragalectomy, patients still have a shortening of the limb, which can require various reconstructive manipulations. We have developed a simple and versatile tibio-calcaneal-navicular arthrodesis (TCNA) technique to reduce limb shortening.

Methods: The main difference from the standard method of arthrodesis between the tibia and calcaneus is that in our method after astragalectomy, the tibia rests with the anterior edge against the os navicularis, and the posterior edge against the calcaneus.

Investigation of the process intergrowth of bone tissue into the hole in titanium implants (Experimental research).

Introduction: Despite the use of modern implants, complications such as nonunion and avascular necrosis of the femoral head are observed in femoral neck fractures (FNF). We have created a new perforated I-beam implant for FNF osteosynthesis and developed a new osteosynthesis philosophy based not only on the mechanical and biomechanical interaction of the bone-implant system, but also on the interaction of the biological properties of the bone and the implant. The purpose of the work is to study the interaction of the biological process of the bone - its regeneration (germination) of bone tissue into the holes of the implant.

Metal Hypersensitivity or Missed Periprosthetic Joint Infection? A Critical Review.

The World Association Against Infection in Orthopedics And Trauma (W.A.I.

Efficiency of an implant: new criterion of objective assessment of implants for osteosynthesis of femoral neck fracture.

Purpose: In line with several designs for osteosynthesis of femoral neck fracture (FNF), their effectiveness is still estimated by the results of biomechanical and clinical trials, finite element method (FE). But surgeons require the criteria which would define their properties in advance and allow improve the results of treatment.

Methods: When new implant (NI) is being designed, we developed such criterion - index efficiency of an implant (IEI) - and performed mathematical comparative researches of properties of NI with the known designs.
