However, clinical studies do not allow for unequivocally determining the underlying causes. The aim of the study is to determine the risk of migration of two geometric types of subtalar implants. Biomechanical tests were carried out on a synthetic bone model with a soft tissue substitute, which allowed for reduction of variability of results caused by biological differences.\u0000\u0000\u0000MATERIAL AND METHODS\u0000A foot model mirroring natural anatomy was made from synthetic bone and a silicone soft tissue substitute with the same hardness as that of the soft tissues of the foot. Two types of 11 mm Ti6Al4V titanium alloy implants were studied, namely, a rectangular subtalar screw and a cylindrical subtalar screw, a type commonly used in flatfoot reconstruction surgery in children. The screws were placed in the sinus tarsi and subjected to cyclic loading (up to 1,000,000 cycles at a frequency of 5 Hz, with a maximum load of 500 N). Comparative pull-out force tests were performed immediately following implantation and after the dynamic loading test. Wyniki. Following the dynamic loading test, all 12 samples were qualified for the pull-out force test. Cylindrical screws demonstrated higher pull-out force values both for the samples tested immediately following implantation and for those that underwent dynamic loading. Implants of the same shape did not show statistically significant differences in the Mann-Whitney U test (p >0.05). Wniosek. The synthetic research model produces reproducible results in the assessment of risk of implant migration. Long-term loading does not significantly affect the risk of implant migration.","PeriodicalId":19622,"journal":{"name":"Ortopedia, traumatologia, rehabilitacja","volume":"58 1","pages":"121-132"},"PeriodicalIF":0.0,"publicationDate":"2022-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88489772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current literature, however, brings contradictory reports as to its effectiveness, which, at least in part, should be attributed to the diversity of methods for producing the concentrate, including the use of various volumes of whole blood, single vs double centrifugation vs filtration, use of thrombin vs calcium chloride to activate the process, and, finally, the use of an anticoagulant. The aim of the study was to retrospectively evaluate the effectiveness of high-volume PRP therapy with the Angel® system (Arthrex) in our patients.\u0000\u0000\u0000MATERIAL AND METHODS\u0000A total of 400 therapies were performed on 299 patients. The most frequently represented indications were knee osteoarthritis (OA), n = 164, including mild (n = 30), moderate (n = 38), and advanced (n = 96) stage; lumbar degenerative disc disease (LDDD), n = 54; rotator cuff injuries (RCI), n = 52; lumbar spinal stenosis (LSS), n = 37; cervical degenerative disc disease (CDDD), n = 17; and shoulder OA, n = 12. Therapies for LDDD and LSS patients were additionally divided with respect to the route of administration (periradicular vs epidural). The assessment tool was the modified Macnab scale. Follow-up examinations were performed at two and six months after PRP administration. Indicators of treatment success were defined as the percentage of satisfactory results and the percentage ratio of satisfactory results to non-satisfactory results after 2 and 6 months of follow-up (S/NS2 and S/NS6). For the advanced stage of knee OA, the results were compared in three age groups (under 66, 67-73 and over 74).\u0000\u0000\u0000RESULTS\u0000For the entire treatment group, the mean S/NS2 ratio was 1.56; in the group of the most frequently represented indications, the highest satisfaction ratio was obtained in LDDD (2.84), and the lowest in the group of RCI (0.96). The mean value of the S/ NS6 ratio was 2.24, being the highest in mild knee OA (4.79) and CDDD (4.67), and the lowest in shoulder OA (0.72). In the age group over 74 years, the frequency of non-satisfactory results shows an increase in patients with advanced knee OA.\u0000\u0000\u0000CONCLUSIONS\u00001. High-volume PRP therapy can be used as a local regenerative and anti-inflammatory treatment, demonstrating the highest efficacy in early knee OA and CDDD. 2. High PRP therapy demonstrates a high safety profile. 3. The final effects of the therapy develop over a period of several months of follow-up and depend on the severity of the degenerative process and the patient's age.","PeriodicalId":19622,"journal":{"name":"Ortopedia, traumatologia, rehabilitacja","volume":"170 1","pages":"43-60"},"PeriodicalIF":0.0,"publicationDate":"2022-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77494165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The idea is expressed that modern clinical and instrumental diagnostic methods comprise a large number of techniques, but no single algorithm for diagnosing injury to the AC joint has been developed. A gold standard for investigating and diagnosing acute AC joint dislocation does not currently exist.\u0000\u0000\u0000MATERIALS AND METHODS\u0000A retrospective study of the characteristics and capabilities of clinical and instrumental diagnostic methods was performed in 152 patients with traumatic shoulder pathology. The patients were divided into two groups: Group I of 102 patients (67%) with acromioclavicular joint dislocation type III-VI according to Rockwood classification and Group II of 50 patients (33%) with a partial tear of the rotator cuff. Clinical and instrumental examinations involved specific provocative tests; the radiological diagnostics comprised conventional radiographs with the Zanca, axillary and Alexander views, and CT, MRI, and ultrasound examinations.\u0000\u0000\u0000RESULTS\u0000The characterization of examination methods was based on the records of patients in Group I and II. The most sensitive clinical test to establish Rockwood type V of acromioclavicular joint dislocation was the Paxinos test (91%). The lowest sensitivity across the tests used was observed with the active compression test to diagnose type IV of dislocation (50%). As regards the X-ray examination, the axial view was 100% sensitive for detecting type IV and VI AC joint dislocation. The Zanca view is highly sensitive for patients with Rockwood type V and Alexander view for Rockwood type III and V dislocations. The accuracy of ultrasound work-up in Group I was 95%, with 96% sensitivity and 93% specificity, while MRI accuracy was 97%, with 96% sensitivity and 98% specificity, and CT accuracy was 81%, with 83% sensitivity and 75% specificity.\u0000\u0000\u0000CONCLUSIONS\u00001. Determination of the sensitivity and specificity of the X-ray examination revealed the absence of a 100% effective X-ray view for type III and V AC joint dislocation. 2. The accuracy and sensitivity of the ultrasound, MRI, and CT examinations are high. 3. There is currently no consensus on a protocol to view acute AC joint injuries. 4.

The complicated anatomy of the elbow joint necessitates careful assessment of the damage before individually adapting treatment methods. The aim of the study was to evaluate the effectiveness of comprehensive treatment of children in Group A in relation to children in Group B. Moreover, the impact of rehabilitation on the function of the affected elbow joint was examined.\u0000\u0000\u0000MATERIALS AND METHODS\u0000The study enrolled 40 children divided into two groups: Group A and Group B.

In Group B, stabilization was performed in less than half of the children and rehabilitation was carried out at home. The initial and follow-up examinations were carried out in both groups according to a medical test card. In Group A, the initial examination was performed on the day the rehabilitation commenced, and the follow-up examination after the completion of a 10-day rehabilitation cycle.
