Gushcha A.O., Kolesov S.V., Poltorako E.N., Kolbovskiy D.A., Kaz’min A.I.


Purpose: to compare the results of surgical treatment of patients with multilevel lumbar vertebral canal stenosis. Patients and methods. Prospective randomized multicenter study included 71 patients aged 41 - 79 years. In the 1st group of patients (n=38) a standard wide decompression of the spinal canal, transpedicular fixation of one clinically and roentgenologically significant spinal motion segment using rigid stabilization and interbody fusion was performed. In the 2nd group (n=33) microdecompression of the spinal canal, transpedicular fixation of one clinically and roentgenologically significant segment using the rods of nitinol transpedicular device. The results were assessed by the pain VAS, ODI and SF-36 questionnaires, roentgenologic, CT and MRI data. Results. Mean follow up made up 1.5 years, the maximum one - 3.0 years. Significant pain relief and im- provement in the quality of life as compared with the preoperative level was reported for both groups. No sig- nificant difference between the groups was observed. Functional roentgenograms showed within 5° (4.2 - 6.5°) preservation of motion in the stabilized segment only in patients from the 2nd group. Adjacent segment pathology in 12 months after operation was diagnosed only in 1 patient from the 1st group. Conclusion. Preliminary results allow considering the dynamic transpedicular fixation using nitinol rods as an effective surgical technique for the treatment of degenerative lumbar spine pathology.

Potentialities of diffusion weighted MRI in the assessment of the degree of adjacent intervertebral disc degeneration: rigid lumbosacral stabilization and total intervertebral disc arthroplasty

Byval’tsev V.A., Stepanov I.A., Pestryakov Y.Y.


Purpose: to evaluate the condition of adjacent intervertebral discs (IVD) after single level rigid lumbosacral stabilization and total arthroplasty by calculating IVD height index and apparent diffusion coefficient (ADC). Patients and methods. The study included 117 patients (64 women and 53 men) after rigid lumbosacral stabilization or total arthroplasty of the degenerative IVD at L5-S1 level. Values of ADC and height of the adjacent IVD were assessed prior to surgery, at discharge and in 6, 12, 24 and 36 months after surgical intervention. Results. The value of the height of the adjacent IVD in patients after rigid stabilization in the early postoperative period averaged 0.58±0.046, in 6 months - 0.58±0.044 and 0.52±0.037 in 36 months after surgery. In patients after total arthroplasty it made up 0.59±0.041, 0.60±0.038 and 0.56±0.02, respectively. Comparison of the adjacent IVD height indices showed significant difference starting from the 12th observation months (p<0.05). In group of patients after rigid stabilization the value of ADC made up 1547.7±231.4 mm2/s in the early postoperative period, 1314.5±117.9 mm2/s in 6 months and 1189.3±117.9 mm2/s in 36 months after surgery. In patients after total arthroplasty it was 1539.7±228.9 mm2/s, 1477.3±245.1 mm2/s and 1334.5±217.6 mm2/s, respectively. Statistically significant difference in ADC values between 2 groups of patients was noted in 6 months after surgery and later (p<0.05). Conclusion. Diffusion weighted MRI with ADC calculation is a modern noninvasive diagnostic method for early stages of adjacent IVD degeneration. In contrast to rigid lumbosacral stabilization, total IVD arthro- plasty enables to delay slightly the degeneration of segments adjacent to the operated level.

Krivoshein A.E., Konev V.P., Kolesov S.V., Byval’tsev V.A., Kaz’min A.I.


Purpose: to elaborate the criteria for the assessment of the degree of spinal motion segment degradation at various methods for posterior spine fixation in experiment. Material and methods. The study included mongrel dogs with body mass of 12±1.5 kg aged 21±3 months. Transpedicular lumbar spine fixation was performed with either rigid titanium alloy rods (1st group, n=5) or dynamic nitinol rods (2nd group, n=5). X-ray examination and morphologic study of the structural elements of spinal motion segment (SME) were performed to all animals in 3, 6, 12, 18 and 24 months after surgery. Results. Functional examination showed that in both groups the range of motion made up 18±1.2° preoperatively. In the 1st group of animals the range of motion in the operated SME made up 0±0.03°. In the second group the range of motion was preserved throughout the experiment and averaged 15±1.3° that made up 78.9% of the preoperative range. In both groups the disc height at the fixation level was constant throughout the experiment and made up 0,3±0.003 cm pre- and postoperatively. Obtained roentgenologic and morphologic data indicated that posterior dynamic spine fixation with nitinol rods ensured more balanced distribution of loads on the supportive elements of the construction and enabled prevent the development of the adjacent segments degeneration. Based on the study results the criteria for the assessment of the degree of the facet joints and discs degradation were formulated.

Positioning of custommade acetabular components at revision hip arthroplasty: do they really match as “a key and a lock”?

Kovalenko A.N., Tikhilov R.M., Bilyk S.S., Shubnyakov I.I., Cherkasov M.A., Denisov A.O.


Purposes are to determine 1) what frequency and what degree is of custom acetabular implants malposition in comparison with planned position, 2) what the reason of malposition is and 3) what the malposition consequences we can wait for. Patients and methods. The observation group included 20 patients (18 women and 2 men) with severe acetabular defects. Mean age of patients made up 53 (22-72) years. Position of the implants was compared with the parameters of preoperative planning using 5 postoperative CT indices (inclination, anteversion of semi- spherical part of the implant, spatial location of the rotation center in three axes). More than 10° deviation for inclination or anteversion and 5° dislocation of the rotation center in any axis was considered as a malposition of the component. Results. Only 5 of 20 constructions matched conditionally permissible limits by all the parameters. Most often excessive dislocation of the rotation center in lateral direction (10 cases) and excessive anteversion (9 cases) were observed. During 6 weeks follow up no complications related to the acetabular component position were recorded. Conclusion. It was shown that at revision arthroplasty with custom-made implants the probability of implant malposition as compared to the preoperative plan. The main reason could be the complexity of intraoperative orientation under conditions of abnormal hip anatomy. Malposition of the implants beyond the stated values did not result in complications within the early postoperative period. The longer follow up is required for the assessment of the long-term results.

Zelichenko E.A., Guzeev V.V., Koval’skaya Y.B., Gurova O.A., Guzeeva T.I.


Introduction. Osseointegration process exerts considerable influence on the term of biological fixation of the implants and is an important parameter that is to be focused on at the implant placement. Purpose: to conduct a comparative analysis of the osseointegration of the titanium alloy implants with different coatings for the determination of the optimum coating compound for osteogenesis. Materials and methods. Comparative analysis of osteogenic properties of the implants with thermal chemical surface treatment, calcium phosphate coating and Germanium enriched (3% and 5%) calcium phosphate coatings applied by electrochemical technique was performed. Implant recipients were 29 not pedigree male cats aged 1.5 to 4.0 years with 2500 to 3400 g body weight. Experimental animals were euthanized in 90 days after surgical intervention. Results. Histological study results showed that bone tissue regeneration was most active when implants with higher level (5%) of Germanium in calcium phosphate coating were used. Calcium phosphate coatings and Germanium enriched ones showed better osseointegration as compared to the implants with thermal chemical surface treatment.

Dynamics of the formation of protection for circulatory bed in bone regenerate

Shchyurov V.A., Boichuk S.P., Tarchokov V.T., Mel’nikova L.V.


Evaluation of the bone regenerate maturation in 21 patients, aged 27 - 66 years, with closed shoulder fractures was performed in the course of treatment by Ilizarov technique according to the rate of blood supply velocity at functional load and by the value of that load. Examination was performed in 1 and 2 weeks as well as in 1 and 2 months after fixation. Within the first 2 weeks the bone fragments micro mobility at 10 kgF axial load on the extremity made up 194±42 µm. Subsequently as the regenerate became compact the bone fragments micro mobility decreased up to 53±13 µm (p≤0.02). During the fixation period the load tolerance increased from 5 to 15 kgF. The threshold of load tolerance was detected by the occurrence of unpleasant feel- ings the regenerate zone and increased rate of blood circulation in the vessels. At the end of fixation period the rate of blood circulation was decreased by 2 times and practically did not change at increasing loads confirming the formation of the protection system for circulatory bed in the bone regenerate.
