The purpose of the study was to analyze the medium- and long-term results of hip arthroplasty using Paavilainen technique in patients with the congenitally dislocated hip. Methods: From 2001 to 2012 180 operations were carried out were using the Paavilainen technique in 140 patients with high dislocation of the hip (Crowe IV). All patients were clinically evaluated using the Harris Hip Score (HHS), VAS and radiography. Statistical analysis was performed using the Pearson correlation coefficients, multiple regression analysis and classification trees analysis. Results: The average Harris score improved from preoperative 41.6 (40,3-43,5) to 79.3 (77,9-82,7) at final follow-up, and the difference was significant. Early complications were 9% (the most frequent were fractures of the proximal femur), later - 16.7% (pseudoarthrosis of the greater trochanter, 13.9%; disclocations-1,1%, aseptic loosening of the components - 1.7%), reoperation performed in 8.3% of cases. Such factors as age and limb length has statistically significant effect on functional outcomes. Established predictive model allows to get the best possible functional outcome in such patients with severe dysplasia. Conclusions: Total Hip arthroplasty using the Paavilainen technique is an effective method of surgical treatment in patients with the congenitally dislocated hip, but it is technically difficult operation with a high incidence of complications in comparison with standard primary total hip replacement.

«Frozen shoulder» is a common problem and difficult to treat. The present prospective randomised single-blind controlled trial evaluates the efficacy of the fascial distortion model according to Typaldos as a remedy for the «frozen shoulder». Material and methods. A total of 60 patients were randomised to receive either the FDM-guided treatment (FDM, n = 30) or a «conventional» manual therapy (MT, n=30). The primary endpoint for the treatment effect was the shoulder mobility, and secondary endpoints were pain (measured on a VAS), raw force and function as expressed by the Constant-Murley and DASH scores. Results. Before therapy groups were well comparable in terms of all outcome parameters. All endpoints showed a substantial and significant improvement in both treatment groups. Improvement was significantly more marked in the FDM group as compared to the MT group, and the effect occurred significantly faster. During posttreatment observation, there was no further improvement and the achieved benefit in mobility in the FDM group decreased. However, the abduction ability of 15,2±37,2° continued to be substantially better than in control patients (124.1±38.6°, p <0,01), and the ultimate improvement in abduction was 59.4° (64% more than baseline) as opposed to 25.9° (27%) in controls. Secondary outcome parameters (raw force, functional handicap, and pain) showed a significant improvement in both groups but a significantly better result in patients treated according to FDM guidelines. However, patients in this group experienced pain during the treatment more frequently (21/27 vs. 10/27, P < 0,01 ). Conclusion. «Frozen shoulder» treatment according to the FDM is an effective modality with swift onset of action and acceptable side effects that is superior to conventional manual therapy. Long-tern effects, and modes of action need to be investigated.

Skeletal dysplasias are challenging for diagnostics and treatment. We present a series of fifteen patients with different forms of skeletal dysplasias with age ranged from 6 to 17 years with variable clinical presentations managed as a part of the project of scientific cooperation between Turner Paediatric Orthopaedic Institute and Orthopaedic Hospital Vienna-Speising. The spectrum of diagnoses included multiple epiphyseal dysplasia, spondyloepiphyseal dysplasia congenita, diastrophic dysplasia, metaphyseal dysplasia, spondylometaphyseal dysplasia, Stickler syndrome, Kniest dysplasia, and anauxetic dysplasia. Complex treatment, which included axial correction and juxta-articular realignment, was performed as a single-stage, or consecutive surgery. Surgical techniques included corrective osteotomies with internal fixation, guided growth technique and external fixation devices. Best results (full axial correction, normal alignment of the joint) were achieved in 8 patients, including 2 patients with metaphyseal dysplasia, 2 patients with multiple epyphyseal dysplasia, 2 patients with spondyloepyphyseal dysplasia, patient with Stickler syndrome and patient with spondylometaphyseal dysplasia. Good results (partial correction at the present time) were seen in 4 patients (2 patients with Kniest dysplasia, 1 - with multiple epyphyseal dysplasia and 1 - with anauxetic dysplasia). Satisfactory results (non-progressive condition in previous progression) were obtained in 2 patients with diastrophic dysplasia, and poor results (progression of the deformity) - in 1 patient with diastrophic dysplasia. Positive results in most of the cases of our series make promising future for usage of complex approach for orthopedic management of children with skeletal dysplasias; advanced international cooperation is productive and helpful for diagnostics and management of rare diseases.

The purpose - to optimize the quality of perioperative management of adolescents with damage of the anterior cruciate ligament of the knee. Material and methods: Perioperative methods of anesthesia in 71 patients were estimated. Psycho-emotional status was evaluated on the basis of determining the level of reactive anxiety (Spielberg Hanin scale) and intraoperative anesthesia (unilateral spinal anesthesia or combined) has been chosen. Results: According to the results of lactate and glucose levels in the blood the efficacy of unilateral spinal anesthesia during surgery was demonstrated. Visual analog scale revealed the advantage of extended continuous iliofascial block over an isolated femoral nerve blockade for adequate analgesia for postoperative period. The advantages of the performing continuous iliofascial block under ultrasound were demonstrated.

Aim: to find the optimal configuration of passive computer-assisted ORTO-SUV device for the correction of complicated midfoot and hindfoot deformities. Material and methods: The study was carried out using plastic “shin-foot”complexes, on which different versions of Orto-SUV device layout: five versions for midfoot deformities and three versions for hindfoot deformities. A model providing maximum amplitude of the movement was considered optimal. Results: Optimal layout for midfoot provides dorsiflexion of 41,1±1,7°; plantar flexion - 32,1±1,4°; supination - 53,3±1,8°; pronation - 35±1,6°; abduction - 44,2±2,1°; adduction - 43,2±1,7°. Optimal layout for the correction of hindfoot deformities provides rotation in sagittal plane upwards - 96,5±2,4°;rotation in sagittal plane downwards - 36,2±1,4°;“varusation” (angulationmedially in the frontal plane) - 31±1,3°; “valgusation” (in the frontal plane outwards) - 44,5±1,9°; movement upwards and backwards, angle of 45° to the horizontal plane - 86,4±1,2 mm; movement downwards and anteriorly, angle of 45° to the horizontal plane - 81,5±1,1 mm.

Tarsal coalition - is an abnormal fusion between two or more tarsal bones which can lead to foot pain, progressive foot deformity, and frequent ankle sprains. Radiological diagnosis of tarsal coalitions on the standard plain radiographs is difficult because of indirect visualization of the fusion zone. Computed tomography is helpful for confirmation of the diagnosis. Purpose: to determine diagnostic value of indirect radiological signs of tarsal coalitions. Material and methods. The analysis of the radiographs of 25 patients with confirmed tarsal coalitions and the radiographs of 37 patients with valgus deformities of feet without tarsal coalitions. Results. The sensitivity and specificity of tarsal coalitions radiological signs were determined. Sensitivity of the "anteater nose" in our study was 92,3%, specificity - 94,31%; C-sign had sensitivity 88,89% and specificity - 77,08%; “talar beak” symptom had sensitivity 36,36 percent and specificity - 97,14%. Conclusion. Sensitivity and specificity of indirect radiological signs of tarsal coalitions determined in our study have sufficient diagnostic value, and computed tomography of the foot should be done for confirmation of diagnosis.

The study aimed a comparison of treatment results in patients with two-column acetabular fractures (AO, Type C) when using different operative approaches: ilioinguinal (12), Y-type (16) and a combination of posterior-lateral and ilioinguinal approaches (3). Surgical treatment was carried out not later than 3 weeks after injury. The joint congruence was reached in all the cases. The operative time, blood loss, complications, long-term results of treatment were evaluated. The study showed the effectiveness of ilioinguinal approach in case of the simple two-column fractures. When treating patients with complex fractures of the anterior column, the authors found no significant difference in operative time and intraoperative blood loss between the cases of V-type and combined approaches. In patients with two-column fractures accompanied with posterior wall lesion the time of surgery was significantly lower when using the Y-shaped approach as against the two different approaches.

Authors describe the proposed method of bone plasty using the template made of an aluminum foil. The detailed description of this option and some clinical cases are presented. Clinical application of the proposed method has shown its high efficiency.

Ossificans progressive fibrodysplasia (OPF) presents a rare genetically caused osteopenia manifested by calcification and ossification of muscles, tendons, ligaments, fascia, and subcutaneous tissues due to aggressive fibroblasts proliferation. The disease is usually associated with congenital skeletal abnormalities: clinodactyly of the first toe, ankylosis of the first interphalangeal joints, and flexion contracture of the first finger. Surgical attempts of ossifications excision are unsuccessful and worsen the situation. 5 patients with OPF are presented. A course of the disease, clinical pattern, and surgery outcomes are disclosed. Both orthopedic manifestations such as congenital hand and foot abnormalities being a key to early clinical evaluation and secondary changes are described in detail. Also, postoperative complications are presented. Surgeonsare recommended to be on guard against this disease when planning the operations for heterotopic ossifications as well as for relating hand and foot abnormalities.

The authors have analyzed scientific works on various aspects of the problem of knee arthroplasty connected with the pathology of periarticular soft tissues. One of the main goals was to trace the evolution of flap surgery principles in the treatment of patients with this pathology. It has been stated that today we can trace two sides in «the problem of soft tissues». The first one in the historical perspective is an operative management of complex wounds following knee arthroplasty, and this side has been studied well enough. The second one is the prophylaxis of skin necrosis and wound infection via flap surgery. This problem is still far from solving. Although in the tradition of world orthopedic surgery pedicled flap transfer and free tissue transfer in the complex cases of knee arthroplasty is not an exclusive practice, the methodology of flap surgery demands further development and scientific foundation.
