Purpose: To assess age related manifestations of the femur and tibia in patients with vitamin D-resistant rickets (VDR) and explore causes for recurrent deformity using imaging modalities.

Methods: Computed tomography (CT), magnetic resonance imaging (MRI) and dual energy X-ray densitometry (DEXA) were used to assess conditions of long bones of lower limbs in patients with vitamin D-resistant rickets aged from 4 years to 30 years preoperatively and after limb lengthening.

Results: Age related MRI findings showed specific structure of the femur and tibia in patients with VDR preoperatively and after operative treatment.

Background: Periprosthetic joint infection (PJI) is a devastating complication of joint arthroplasty. The identification of microorganisms in biofilm-related PJI is challenging yet significant stage of the treatment process. Medical microbiology methods, such as pure culture isolation, remain the gold standard.

In this article, the use of external fixation in the management of juxta-articular fractures in paediatric patients is discussed. Basic principles of Ilizarov technique are described for distal radial, distal femoral, distal humeral and distal tibial fractures. Common indications for external fixation in pediatric fractures are comminuted, complicated, and/or open fractures, particularly at the distal humerus, distal radius, distal femur and distal tibia.

Many orthopaedic procedures require drilling of bone, especially fracture repair cases. Bone drilling results in heat generation due to the friction between the bone and the drill bit. A high-level of heat generation kills bone cells.

Congenital pseudarthrosis of tibia is a genetic, systemic pathology with impaired bone remodeling and unknown pathogenetic mechanisms. Orthopaedic treatment of the disease can fail in some cases. The process of bone remodeling is known to occur under control of local and systemic growth factors, and we sought to explore several osteotropic growth factors, markers of osteogenesis and biologically active molecules in the blood serum of patients with congenital pseudarthrosis of tibia.

For the purpose of comparative analysis of the clinical course of fascial fibromatosis and tissue composition of the palmar aponeurosis in patients of different age groups сase reports and histological surgical material from 179 Dupuytren's contracture patients treated in 2014-2018 were analyzed. Patients were distributed in age groups: the 1st - younger than 50 years, the 2nd - 50-65 years, the 3rd - over 65 years old. In all groups four variants of Dupuytren's contracture clinical course were noted: swift, fast, benign and deffered.

Background: The use of intramedullary elastic nailing is a method of choice for prevention of complications in children with osteogenesis imperfecta. However, the morphology of the growing long bones in the conditions created was not investigated.

Aim: The purpose of our experiment was to study the impact of elastic intramedullary nailing on the histostructure of long bones in their physiological growth.

Early treatment of bone fractures was performed using implants, which are often used in the form of plates of various types, which are fixed on the bone surface (extracellular fixation) and nails that are located in the medullary canal (intracerebral fixation). The goal of this study was to investigate the features of osseointegration of implants for internal fixation (intramedullary or extramedullary) with various bioactive coating techniques. During experimental study on 20 mongrel dogs, the implant model in the form of 1.

Purpose: To explore the role of closed suction drain in multi-level posterior spinal surgery.

Methods: We performed prospective, open-label, randomised control, superiority trial with parallel design and 1:1 allocation. A total of 161 patients undergoing posterior spinal surgery involving more than one motion segment at a dedicated spine surgery department were randomly allocated into "drain" or "no-drain" groups, based on which surgical drain was employed at the end of surgery.

Telescopic rodding has been developed in order to obtain long-lasting osteosynthesis in the growing long bones of children with osteogenesis imperfecta (OI). The major and still unsolved drawback of any telescopic rod or nail design is a lack of rotational stability and, currently, no telescopic system allows immediate weight-bearing. When these problems are associated with insufficient longitudinal bone stability and diminished healing capacity, the result can be unfavourable causing secondary bone fragment displacement, delayed or non-union.

Aim: To investigate the structural and functional characteristics of palmar hypodermal tissue vascularization in Dupuytren's contracture patients of different age groups.

Methods: Eighty-seven Dupuytren's contracture patients underwent partial fasciectomy. Twenty-two of them were less than 55 years old (Y-group, = 22); the others were 55 and older (O-group, = 65).

Limb lengthening by Ilizarov lengthens not just the long bone, but also the soft tissues too. Damage of the muscles during corticotomy and their stretching during distraction play a crucial role in occurrence of complications and final limb function. We present here a systematic codified nomenclature system of each muscle summarising all the influence that corticotomy and distraction have the particular muscle and demonstrate the same in the setting of tibial lengthening.

Introduction: Ilizarov bone transport for large bone defect is challenging and may end in distraction osteogenesis failure.

Material And Methods: Ten forearm and seven tibial defect cases with failed regeneration due to ischaemia during bone transport were studied retrospectively. Mean forearm and tibial defects were 5.

Ilizarov is an accepted technique for lengthening short amputation stumps to improve prosthetic function and rehabilitation. The relation of stump lengthening and phantom limb pain (PLP) has not been reported in literature. We present here a case report of a transfemoral amputee who had a flare up of PLP following stump lengthening.

Peroneal neuropathy is one of the complications of orthopaedic leg lengthening. Methods of treatment include slowing of distraction and decompression both of which may lead to additional complications. The purpose of this study was to analyse the changes in histologic peroneal nerve structure during experimental orthopaedic lengthening using various modes of manual or automatic distraction.

We propose an in vitro method for studying permeability of spinal cord dura mater for components of autological serum using an original device. Sixty native samples of the spinal cord dura mater obtained from 12 mongrel dogs were used for testing of the device. The coefficient of permeability variation (V) for blood serum substances did not exceed 5% in most cases excluding lactate (V=8.

Aim: To determine peculiarities of tissue responses to manual and automated Ilizarov bone distraction in nerves and articular cartilage.

Methods: Twenty-nine dogs were divided in two experimental groups: Group M - leg lengthening with manual distraction (1 mm/d in 4 steps), Group A - automated distraction (1 mm/d in 60 steps) and intact group. Animals were euthanized at the end of distraction, at 30 day of fixation in apparatus and 30 d after the fixator removal.
