Correction of deformities and lengthening of the lower extremities in patients with healed congenital pseudarthrosis of tibia (cCPT) is associated with certain characteristics, difficulties, and complications. But even the restoration of the anatomy and length of the tibia does not solve the problem of further recurrence of the deformity. Aim. This study aimed to evaluate the results of the correction of deformities of the tibia in patients with congenital pseudarthrosis of the tibia after achieving union by using external fixation and guided growth. Materials and methods. The results of treatment of 19 patients with cCPT, aged 4–15 years, which were observed in the Department of the Turner Scientific Research Institute from 2013 to 2018 years, were analyzed. We analyzed the types of deformities before the stage of correction deformities, evaluated the accuracy of the correction deformities after two-level osteotomies of the tibia, and used ortho-SUv passive computer nav...

This study aimed to estimate the results of congenital long bone deformities using the consecutive application of guided growth and external fixation. Materials and methods. We performed a retrospective analysis of the treatment results of 38 children with congenital deformities of long bones. Group 1 consisted of 17 children who underwent consecutive application of two methods: guided growth and external fixation. Group 2 (control group) consisted of 21 children who underwent isolated lengthening and deformity correction by external fixation. Results. There were 14 complications in group 1 and 25 complications in group 2. Moreover, only seven cases in group 1 had complications requiring surgical treatment, whereas 17 cases in group 2 required operative treatment for complications. There was a relatively low level of refractures: zero cases in group 1 and three cases in group 2. The most common complication was a recurrence of deformity associated with the continuous growth of ...

To retrospectively analyze the results of two treatment methods for lower leg deformities associated with partial growth arrest. Materials and methods. Group I comprised 15 children who underwent osteotomy, acute overcorrection, and external fixation by Ilizarov with subsequent lengthening of the segment. Group II comprised 13 patients who underwent epiphysiodesis of the healthy part of the growth plate by drilling, osteotomy with external fixation by use of an Ortho-SUV Frame, and subsequent gradual deformity correction and lengthening. Results. In group I, overcorrection of varus deformities by mechanical axis deviation (MAD) was 18.28 ± 5.25 mm, overcorrection by mechanical medial proximal tibial angle (mMPTA) was 14.86 ± 4.45°, and overcorrection by mechanical lateral distal tibial angle (mLDTA) was 12.85 ± 3.02°. Overcorrection of valgus deformities according to MAD was 15.12 ± 8.28 mm, overcorrection by mMPTA was 10.38 ± 2.77°, and overcorrection by mLDTA was 7.5 ± 3.9°. ...

To retrospectively assess treatment outcomes of long bone deformities of the lower extremities accompanied by shortening in pediatric patients using a software-assisted Ortho-SUV Frame.Materials and methods. The accuracy of deformity correction (AC), period of deformity correction (PDC), external fixation index (EFI), and number of complications in 213 patients were retrospectively analyzed.Results. According to different parameters, AC of femur deformity correction (group 1) varied from 90% to 96%. The average length increase was 47 ± 12 mm. The average distraction duration was 38 ± 14 days. The average PDC was 8 ± 6 days for simple deformities (SDs), 14 ± 7 days for moderate deformities (MDs), and 23 ± 12 days for complex deformities (CDs). EFI was 26 ± 8 days/cm for SDs, 31 ± 6 days/cm for MDs, and 35 ± 12 days/cm for CDs. According to different parameters, AC of the lower leg deformity correction (group 2) varied from 89% to 95%. The average length increase was 52 ± 20 mm. ...

The purpose of this study was to analyze the initial experience with adolescents treated for long-bone deformities of the lower extremities of different etiologies using osteotomies and fixation by interlocking nails.Materials and methods. We analyzed the accuracy of long-bone deformity correction using referent lines and angles, the time of consolidation, number of complications, and functional result.Results. We found that the accuracy of femur deformity correction (dependent on the complicity of the deformity), as estimated by different parameters, varied from 77.8% to 91.7%. Simple deformities and deformities of moderate complicity had the most accurate correction; the group of complex multiplanar deformities of the femur had the least accurate correction. This group included five cases of residual deformity, in which three of these had an angle of residual deformity <10°. The accuracy of leg deformity correction was 90%. Evaluation of the functional results using the L...

Union rates of 86% and complication rates of 29% have been reported 1,2. Circular external fixation has been used successfully, however the presence of an implant restricts pin position opions, and risks endoprosthetic infection 3,4. A novel percutaneously inserted Extracortical Clamp Device (ECD) was developed to allow stable capture of the endoprosthetic femoral fragment without disturbing the prosthesis or cortical envelope and to permit a minimally invasive external fixation solution to achieve union without fracture site or prosthetic bed violation.

The main advantage of these frames is capability to make mathematically precise correction of bone fragments in three planes and six degrees of freedom on the base of calculations made in special software application. Recently these devices are mostly applied in long bone deformity correction but the sphere of its effective useis not limited by only this direction. The article presents the history of investigation of these devices, their development, implemented comparative analysis of the basic hexapods: TSF (Taylor Spatial Frame), IHA (Ilizarov Hexapod Apparatus) and Ortho-SUV Frame.
