Dokolin S.Y., Varfolomeev A.P., Kuz’mina V.I., Artyukh V.A., Marchenko I.V.

Abstract

Purpose — to evaluate mid-term outcomes of reverse joint replacement in patients with shoulder arthropathy and massive rotator cuff tear.

Material and Methods. Reverse shoulder arthroplasty with delTa xTeNd (depuy) was performed in 38 patients in the period from december 2010 to december 2016 by the same surgical team. patients’ age ranged from 38 to 82 years. Indications for replacement were pain syndrome and pseudoparalysis of the upper limb in presence of a large or massive Rc tear as well as shoulder arthropathy of various severity degree. Outcomes were evaluated by standard aSeS, cS and ucla scales. Roentgenological examination included ap and axial x-rays during follow up from 1 to 6 years after the surgery with analysis of implants positioning. Mean follow up was 24,2±6,6 months.

Results. good outcomes were reported in 6 (15,8%) patients. average functional scores were: aSeS 87,4±2,1, ucla 29,7±1,5 and cS 14,0±2,3. Satisfactory outcomes were observed in 27 (14,2%) patients: aSeS 76,2±2,3, ucla 26,8±1,3 and cS 22,0±1,4 scores. poor outcomes were reported in 5 (14,2%) patients with persisting pain syndrome.

Conclusion. To avoid significant and multiple complications after reverse shoulder replacement a precise preoperative planning considering particular destructive changes of glenoid fossa is required. For young and physically active patients the authors recommend to use alternative treatment options aiming at restoration of normal shoulder biomechanics and prophylaxis of arthropathy.

Zinoviev M.P., Paskov R.V., Sergeev S.K., Rimashevsky D.V.

Abstract

Purpose — to evaluate the impact of frontal positioning of prosthesis components after bilateral Tka on short term functional outcomes. 

Material and Methods. The authors performed a retrospective analysis of teleroentgenograms of 466 patients after bilateral Tka with initial varus deformity. Functional and roentgenological outcomes were evaluated at average in 16,4±2,9 months postoperatively. Mean preoperative varus deformity was 10° (from 5 to 25°), initial angle between the anatomical and mechanical femoral axis (FVa) was 6,7±2° (from 3 to 12°). The neutral axis of both lower limbs (Hka = 180±0,5°) was obtained in 99 (21,2%) out of 466 patients. Residual deformity in one of the limbs above 3° with the neutral alignment of the contralateral limb was observed in 44 (9,4%) patients, bilateral residual deformity – in 32 (6,9%) patients. Other 291 patients demonstrated the deviation from mechanical axis in the range from 1 to 3° (±0,5°). all patients were divided into three groups: first group consisted of 10 patients with neutral axis of one limb and varus deformity of the other limb above 3°; second group — 10 patients with bilateral residual varus deformity above 3°; third group — 12 patients with neutral axis of both limbs (Hka = 180°). The angle of residual deformity averaged 3,7° (from 3,2 to 5,1°).

Results. No statistically significant differences between the groups were observed for dynamometric parameters and SF-36 scores, as well as for functional kSS scores (p>0,05). However, the authors reported in patients of the first group a stance phase on the side of residual varus deformity longer at 15% (p<0,05) and transfer phase shorter at 17% (p<0,05) as compared to contralateral limb (with neutral alignment, Hka = 180°), which is indicative of load asymmetry and can have a negative impact at a later stage.

Conclusion. Symmetrical residual varus deformity of lower limbs in the rage of 3,2–5,1° has no negative impact of short term clinical and functional outcomes of Tka. Muscular function and gait properties in patients with neutral axis of the lower limbs and in patients with symmetrical residual varus deformity after Tka were similar 16,4±2,9 months postoperatively.

ARTICULATION AND BACKSIDE WEAR ANALYSIS AFTER LONG-TERM IN VITRO WEAR SIMULATION OF VITAMIN E STABILIZED POLYETHYLENE ACETABULAR LINERS WITH A PRESS-FIT LOCKING MECHANISM

Puente Reyna A.L., Holderied M., Jäger M., Schilling C., Grupp T.M.

Abstract

A previous retrieval study analyzed the backside wear of short-term implanted liners against in vitro tested liners of similar life in service and showed comparable results among both groups, with no significant backside wear due to micro-motion.

The purpose — to obtain a picture of the overall wear (articulation and backside surfaces) of 0.1% vitamin e blended polyethylene liners, with a locking mechanism based on a press-fit cone in combination with a rough titanium conical inner surface in the fixation area, under a 20 million cycles hip wear simulation.

Materials and Methods. A semi-quantitative method was used in order to assess the damage on the backside of the liners and a 3d measuring machine to assess the creep and wear at the articulation surface.

Results. The total average backside wear score was 22.00±2.59 from a maximum total score of 147 after 5 million cycles (mc), increased to 31.92±5.57 after 10 mc, but showed no further increment after 15 and 20 mc. The reference liners (subjected only to axial load) showed similar wear scores and modes as the liners under wear simulation (axial load and movement). Small scratches produced during insertion and removal were clearly seen at the rim (fixation) area and no considerable abrasion was observed. The machining marks on the convex surface were always visible. Regarding the articulation surface, a steady state wear rate of 7 µm/year was measured.

Conlusion. These results determined that most of the backside wear produced on the liners occurred during their insertion and removal rather than during their life in service. Moreover, the wear at the articulation surface was similar to that seen in vivo at short- and mid-term on highly cross-linked polyethylene liners with and without vitamin e content.

FEATURES OF IMAGING FINDINGS IN CHILDREN WITH CONGENITAL THORACIC SPINE DEFORMITY ON THE BACKGROUND OF MALSEGMENTATION OF VERTEBRAE LATERAL SURFACE

Vissarionov S.V., Baindurashvili A.G., Khusainov N.O., Kokushin D.N., Bart V.A., Beletsky A.V.

Abstract

Purpose — to study alterations in the bony structures in cases of congenital deformity of the thoracic spine combined with malsegmentation of lateral surfaces of vertebrae due to pathological processes during growth period of childern and to find correlation with above alterations.

Material and Methods. The study included 30 patients with congenital deformity of thoracic spine combined with malsegmentation of lateral surfaces of vertebrae. age of patients ranged from 3 to 10 years (mean of 7 years). gender distribution — 19 female and 11 male patients. all patients underwent imaging examination including spine roentgenography in two standard views in prone position as well as computer tomography.

Results. Magnitude of deformity scoliotic curve was 67° (45–88°) and of pathological thoracic lordosis — 23° (18–27°). Mean number of block vertebral motion segments included into the main deformity curve was 6 (3–8). Mean distance between the outline of lateral vertebral surface and lateral outline of projection of curve root of apical vertebra on convex side of deformity (aB) was 6 mm (4–10 mm). correlation analysis demonstrated that aB distance mostly depended on the number of vertebral motion segments included into the block along non-segmental area: pearson coefficient 0.67. Based on cT scans the authors observed no rotation component of bodies’ deformity along the non-segmental area.

Conclusion. Children with congenital thoracic spine deformity along with malsegmentation of lateral surfaces  of vertebrae feature pathological lordosis in affected zone. alterations in the bony structures result from asymmetric growth of one half of the vertebral body at the level of non-segmentation. asymmetry severity has a strong correlation dependency from the number of vertebral bodies included in the block along the non-segmental area.

COLD PLASMA NUCLEOPLASTY VERSUS RADIOFREQUENCY ANNULOPLASTY FOR DISCOGENIC PAIN SYNDROME: COMPARATIVE ANALYSIS OF EFFICACY

Volkov I.V., Karabaev I.S., Ptashnikov D.A., Konovalov N.A., Poyarkov K.A.

Abstract

Introduction. The intervertebral disc is considered the main source of pain syndrome in degenerative diseases  of the spine. The methods of laser, mechanical and cold plasma nucleotomy are widely used in Russia and are included into the system of high-tech medical care. The most promising annuloplasty methods are less known and have only recently been introduced into the national surgical practice. patients’ selection criteria and surgical procedure choice are not clearly defined and the information about annuloplasty in the national literature is practically not presented.

Purpose — to conduct the comparative analysis for efficiency of paracentetic nucleoplasty and radiofrequency annuloplasty for discogenic pain and to identify the factors determining the surgery outcomes.

Materials and Methods. The authors performed a retrospective cohort study. patients were divided into two groups: 107 patients underwent cold plasma nucleoplasty (Np), 72 patients received radiofrequency annuloplasty (RFap) at one or several levels. evaluation of outcomes was based on the dynamics of the NRS-11 digital pain scale and the Oswestry index (OdI). Positive results were recognized with decrease of NRS-11 index by 50% (or NRc-11 <4) and OdI by 20% from the original (or OdI <20%) when the outcome was preserved for 6 or more months postoperatively. To identify the factors influencing the outcome the authors assessed the following criteria prior to surgery: clinical findings (acute, chronic or recurrent pain syndrome), severity and prevalence of disc degeneration at the level of intervention and in adjacent segments, the use of other interventional diagnostic methods for excluding other sources of pain.

Results. In results of the procedures the authors reported a decrease of indices in both groups (p<0.001) in the absence of significant differences between the groups (p = 0.672). However, but the number of positive outcomes in the RFap group was higher than in the Np group — 49 (68.1%) and 55 (51.4%) respectively. Significant prognostic factors in the Np group were acute character of the pain syndrome (Spearman ρ = 0.252, p = 0.014), fewer operated levels (ρ = -0.304, p<0.001); in both groups such factors were failure of other procedures (Np ρ = 0.413, p<0.001; RFap ρ = 0.464, p<0.001) and the degree of disc degeneration of adjacent segments (Np ρ = -0.387, p<0.001; RFap ρ = -0.297, p<0.001). With regression analysis the best results were observed under the criteria “failure of other procedures”,  for Np (OR 0.77 at 95% cI (0.682-0.857) and for RFap (OR 0.81, 95% cI (0.701-0.924)).

Conclusion. Both methods of cold plasma nucleoplasty and radiofrequency annuloplasty demonstrate positive and similar outcomes provided the discogenic character of the pain syndrome has been defined correctly. The most significant is the exclusion of other sources of pain by diagnostic blockades, especially for patients with chronic pain syndrome and advanced multi-level lesion of the spine segments.

TREATMENT OPTIONS FOR NEGLECTED ACHILLES TENDON RUPTURED: WETHER SPONTANEOUS HEALING IS POSSIBLE?

Sereda A.P.

Abstract

The paper considers cases of spontaneous healing of achilles tendon with elongation. In such condition the tendon defect is not palpable, active plantar flexion is preserved and patients are complaining for strength diminution.

Purpose — to study features of spontaneous achilles tendon healing with elongation and to analyze the shortening tenoplasty option as a procedure primarily aimed at restoration of strength for gastrocnemius-soleus complex.

Material and Methods. The paper presents features and outcomes of surgical treatment of 25 patients who underwent a shortening tenoplasty of various types: crimping (3 patients), Z-type (2 patients), oblique (1 patient) and transverse (19 patients).

Results. No re-ruptures or other serious complications were observed in the patients of the present study. Treatment outcomes were evaluated by j. leppilahti scale in 304,7±8,9 days after the procedure. postoperative leppilahti scores were statistically significantly better than prior to surgery — 82,4±5,6 and 62,2±7,7, respectively, (p<0,0001). 

Conclusion. Shortening tenoplasty can be indicated in cases of spontaneous achilles tendon healing with elongation. at relatively early stages of the injury with rather elastic scars the crimping tenoplasty can be applied.  At later stages a resection shortening tenoplasty is recommended through a minimal incision with transverse resection of tendon and removal of scar block.

Irzhanski A.A., Kulyaba T.A., Kornilov N.N.

Abstract

The purpose of the work — is validation and cultural adaptation of the english-language rating systems for knee function assessment for use in scientific, medical and educational institutions of the Russian Federation.

Materials and Methods. The english versions of rating systems WOMac® 3.1 Index, The knee Society clinical Rating System©, FjS-12® were translated to Russian language by orthopedic surgeon with advanced level of english and the professional translator specializing in the translation of medical texts. Reverse translation was provided by third independent translator born in the english-speaking country (native speaker). a printed version of the various translations of the questionnaires was filled by patients with an interval of two days. The study group included 150 patients with Stage III knee osteoarthritis (90 women and 60 men aged 48 to 75 years, an average of 62.5 years) hospitalized in Vreden Research Institute of Traumatology and Orthopedics from February to april 2017 for total knee arthroplasty.

Results. good and very good retest reliability of WOMac (α = 0.87 and α = 0.9), kSS (α = 0.89 and α = 0.86) and FjS-12 (α = 0.94 and α = 0.96) was revealed. The study revealed a strong correlation between the results of the questionnaires performed by different translators: WOMac (Icc = 0.89), kSS (Icc = 0.86), FjS-12 (Icc = 0.92). The correlation dependence between subsections of WOMac (stiffness – Icc = 0.98, pain – Icc = 0.87, daily functions – Icc = 0.89) and kSS (knee score – Icc = 0.94, function score – Icc = 0.88), which indicates a good constructive validity.

Conclusion. The results of the study of criterial and constructive validity, as well as the retest reliability of the Russian versions of the WOMac, kSS and FjS-12 scales, indicate that they are a reliable and sensitive tool for assessing the function of knee joint, which can be widely used by Russian researchers in practical and scientific activities.

VALIDATION OF THE RUSSIAN SHOULDER PAIN LEVEL TEST-QUESTIONARY FOR DETECTION OF PATIENTS WITH SUBACROMIAL IMPINGEMENT SYNDROME

Emel’yanenko M.V., Lazko F.L., Gazhonova V.E.

Abstract

Despite multiple available international scales for assessment of anatomical and functional features of shoulder joint, no unified Russian survey for shoulder joint assessment in patients with subacromial impingement syndrome (SIS) has been developed so far.

Purpose — to develop and validate a test-questionary for shoulder pain (SSp) to diagnose SIS in patients with chronic pain syndrome in the shoulder joint.

Material and Methods. Score for shoulder pain (SSp) was validated based on 252 questionnaires including the group of 144 patients with SIS and control group of 108 patients without SIS. age of patients ranged from 50 to 80 years. clinical diagnosis was established using integral clinical and imaging examinations. Internal consistency of survey was evaluated by calculating the cronbach’s alpha. Significance of each question was assessed by calculation of odds ratio (OR). Sensitivity, specificity, accuracy and validation threshold for SIS diagnostics were determined by measuring the area under curve (auc). Re-testing reliability was evaluated by intra-class correlation coefficient (Icc) in 60 patients with an interval of 1–3 days. convergent validity was assessed with aSeS and VaS scores.

Results. Informative value of the full version of SSp was as follows: 97% sensitivity, 90% specificity, 0.96% auc (95% cI 0,93–0,98), р<0,0001. youden’s index (j) equaled 0.88. Validity threshold for SIS diagnostics was above 18. Intra-class correlation coefficient (Icc) was 0,98 (95% cI 0,98–0,99). The authors reported a high inverse correlation with aSeS scale ρ = -0,9498 (r = -0,95; p<0,001) and direct correlation with VaS scale ρ = 0,8279 (r = 0,83; p<0,001). application of a logic regression resulted in a suggested short version of survey which included 13 questions with threshold for SIS diagnosis above 14 scores. This provided for improvement of intra-test reliability up to 0,93 (95% cI up to 0,91) and the level of clinical use of the short survey version.

Conclusion. Short version of survey for shoulder pain (SSp) consisting of 13 questions was validated for clinical use and SIS diagnostics in patients of elderly and middle age with chronic shoulder pain.

Tikhilov R.M., Shubnyakov I.I., Denisov A.O., Konev V.A., Gofman I.V., Mikhailova P.M., Netylko G.I., Vasiliev A.V., Anisimova L.O., Bilyk S.S.

Abstract

Aim. It’s common that revision arthroplasty of the large joints demands replacing of bone defects of irregular geometrical shapes and simultaneous restoring of support ability and ability to integrate surrounding muscular and tendinous structures into an implant that is required for a complete restoration of joint function.

The purpose. To experimentally study the process of integration for muscular and bone tissue as well as tendinous and ligamentous structures into porous titanium materials.

Material and methods. During in vivo experiment the authors created a standardized bone defect in 6 rabbits of chinchilla breed at the point of patella ligament attachment as well as a delamination area of muscular tissue in latissimus dorsi. Both knee joints and both latissimus dorsi were used in each animal. Study group included titanium implants with three-dimensional mesh structure. Control group — solid titanium implants with standard porosity. Titanium implants were produced by additive technologies with preliminary prototyping. The porosity corresponded to trabecular metal, striations — 0.45, pores size —100–200 microns. Study and control components were implanted in the identical conditions into the corresponding anatomical sites. Postoperative AP and lateral roentgenograms of knee joints were performed for all animals. Morphological research was conducted on day 60 after the implantation and strength properties were studied at day 90 after the implantation.

Results. The authors observed bony ingrowth into implant pores with minimal volume of fibrous tissue, a distinct connective integration was reported represented by a dense fibrous tissue in the pores of components implanted into the muscular tissue. Testing of fixation strength of the study implants demonstrated a clearly superior strength of soft and bone tissue integration into the experimental mesh implants produced using additive technologies.

Khominets V.V., Mikhailov S.V., Shakun D.A., Shumagaziev S.E., Komarov A.V.

Abstract

Purpose — to evaluate the efficiency of the proposed method of arthrodesis by three cancellous screws in patients with posttraumatic arthrosis of the ankle joint.

Materials and Methods. After removal of talus and tibia cartilage and autografting the proposed method features placement of foot into the optimal position and fixation of the ankle joint with three cancellous screws. 23 patients with posttraumatic ankle deformity arthrosis of grades III–IV underwent surgery according to the described procedure. Condition of all patients prior to and after the surgery was evaluated using the international ankle and rear foot assessment scale of the American Orthopedic Society of the Foot and Ankle (AOFAS).

Results. In 20 patients (88%) the ankle ankylosis was reported within 2.5 months, which was confirmed by X-ray examination. In 2 patients (8%) the ankylosis took place in the period up to 4 months. Loss of the correct position of the foot with screws migration was reported in one patient (4%). The authors observed that patients with postoperative deviation of the tibiotalar angle not exceeding 5 degrees as compared to a healthy limb demonstrated the best functional outcomes.

Conclusion. The suggested technique ensures a secure fixation of talus in a predetermined position, a single-step compression between the closed joint surfaces and allows an early effective rehabilitation.

SURGICAL TREATMENT OF CERVICAL STENOSIS IN PATIENTS WITH MUCOPOLYSACCHARIDOSIS: SYSTEMATIC REVIEW

Kolesov S.V., Mikhaylova L.K., Kolbovsky D.A., Pereverzev V.S.

Abstract

A multidisciplinary approach to treatment of patients with mucopolysaccharidosis allows to achieve good results. However, progressive spinal canal stenosis at the level of the craniovertebral junction, characteristic of this disease, leads to neurological signs, as well as a decrease in quality and length of life. The solution to this problem is a difficult challenge for spinal surgeons, as it is associated with a high risk of complications. There is also a wide range of opinions and approaches to the surgical treatment of this group of patients.

Using the referred Reporting Items for Systematic Review and Meta-Analysis» (PRISMA) protocol, a PubMed and eLIBRARY search was conducted using keywords to find articles describing patients with mucopolysaccharidosis who underwent surgical treatment for cervical stenosis. In this review, information on demographic parameters, surgical technique and the results of cervical stenosis treatment in patients with mucopolysaccharidosis is collected and analyzed.

TOTAL HIP AND KNEE ARTHROPLASTY IN PATIENTS WITH CHRONIC KIDNEY DISEASE (REVIEW)

Murylev V.Y., Tsygin N.A., Shutov E.V., Zhuchkov A.G., Rukin Y.A.

Abstract

Chronic kidney disease is a common medical problem. It is characterized by a peculiar course leading to renal osteodystrophy resulting in increased risk of fractures and joint lesions with the concomitant need for major joints arthroplasty. Moreover, a wide spectrum of organ and metabolic deteriorations due to renal insufficiency causes a more complicated postoperative period with higher mortality and frequent infectious, cardiovascular, hemorrhagic, thrombotic and surgical complications. The highest risks are noted in patients on long lasting hemodialysis.

To improve the arthroplasty outcomes an adequate correction of anemia, bone-mineral and electrolyte disorders, arterial hypertension and optimization of dialytic modalities must be ensured.
