When the fracture encompasses the articular facet of the bone, maintaining the reduction is challenging due to the fragment's size and high instability. While specific implants have been developed to fix this fragment, their effectives have been limited. This study evaluates the mechanical performance of a novel hook plate conceived to stabilize the small fragment of the semilunar facet of the radius in non-osteoporotic bones. A simulated lunate facet fracture was created in an adult radius in a virtual model, and a modification of a hook plate was developed using computer-aided design (CAD). Two groups were established for the finite element method (FEM) simulation: a control group (standard plate Medartis™ (Switzerland, A-5500.23) and an angled plate with hooks set at 60º, 90º and 120º. In the FEM simulation, an axial load of 100 N was applied in the Z-axis direction on the fragment. Fracture displacement along the Z axis was more pronounced in the control model (0.32 mm) and less in the angled models, ranging from 0.22 to 0.28 mm. Notably, the plate with a 90° angle showed a more effective reduction in fragment displacement. The distribution of stresses in the system showed the highest levels of stress in the control group (59.31 MPa), followed by the subgroup with a 60° angle (55.78 MPa).In the side view, the control model showed a higher concentration of stresses (59.74 MPa), while the model with a 90° angle showed a lower value of stresses (18.87 MPa). Critical stress regions were identified in the bolts of the control and 120° models (59.47 MPa and 57.64 MPa, respectively). However, in the 90° model, no critical regions were observed in the bolts, which showed lower stress values, reaching 26.33 MPa. In the bone, the greatest concentration of stress occurred in the region where the plate was anchored. Our results showed that the 90° hook plate had a superior mechanical performance in fixing simulate lunate facet fractures at the distal radius. This angle led to minor displacements and minimized stress concentrations in the hardware, thus contributing to enhance the stability of this specific fracture.</p>","PeriodicalId":9189,"journal":{"name":"BMC Musculoskeletal Disorders","volume":"25 1","pages":"885"},"PeriodicalIF":2.2,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11539762/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142589722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The self-reporting questionnaire Activity Patterns Scale (APS) assesses these activity patterns and their subscales: Pacing (Pacing to increase activity levels,Pacing to conserve energy for valued activities,Pacing to reduce pain); Avoidance (Pain avoidance,Activity avoidance); Pacing (Excessive persistence, Task-contingent persistence, Pain-contingent persistence). This investigation translated the APS into German and estimated its internal consistency, test-retest reliability, and construct validity. The APS translation was conducted following international guidelines for the transcultural adaptation of self-reported measures. For the construct validity, the Avoidance Endurance Fast-Screening (AE-FS), Tampa Scale of Kinesiophobia (TSK), and Coping Strategies Questionnaires (CSQ) scales were employed. Sixty-five participants with MSP contributed to a baseline survey with a follow-up at two weeks. The German version of the APS subscales demonstrated good internal consistency (Cronbach's alpha = 0.670-0.89) and satisfactory test-retest reliability (intraclass correlation coefficient = 0.72-0.82); only Task-contingent persistence revealed a poor result. Construct validity was supported by significant correlations between APS subscales (pacing, avoidance, persistence) with related measures, including the Coping Strategies Questionnaire (0.27 to 0.40; -0.50 to 0.55; 0.27 to 0.50), the Tampa Scale for Kinesiophobia (0.28 to 0.47; 0.36 to 0.37; 0.38), and Avoidance-Endurance Fast Screening Pain Persistence Scale (none; none; 0.40). The findings demonstrate high construct validity by the substantial correlations in the predicted directions for the APS subscales and their corresponding questionnaires.

Promoting bone regeneration and reversing its loss by infusion of exogenous bone marrow mesenchymal stem cells (BMSCs) is a potentially effective treatment for osteoporosis.

Stromal cell-derived factor 1 (SDF1) is a chemokine that induces targeted cell migration through the SDF1/CXCR4 (C-X-C chemokine receptor 4) axis and can induce migration of exogenous mesenchymal stem cells to sites of high SDF1 concentration.

The literature that met the inclusion criteria was strictly screened out, the literature information was extracted, and the data were input into RevMan5.4 for analysis.</p><p><strong>Results: </strong>Ten studies (12 controls) with 625 patients were included. Overall, the visual analog scale (VAS) score (mean difference (MD) = -0.53, 95% confidence interval (CI) (-0.76, -0.31), P < 0.00001), range of motion (ROM) (MD = 7.24, 95% CI (2.79, 11.69), P = 0.001), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score (MD = -6.91, 95% CI (-9.47, -4.34), P < 0.00001), cartilage recovery (cartilage thickness: MD = 0.43, 95% CI (0.35, 0.51), P < 0.00001; cartilage regeneration: relative risk (RR) = 1.81, 95% CI (1.40, 2.33), P < 0.00001; and the International Cartilage Repair Society (ICRS) grade: RR = 1.96, 95% CI (1.44, 2.66), P < 0.0001), and the Lysholm score (MD = 6.51, 95% CI (4.97, 8.04), P < 0.00001) after HTO-PRP treatment had certain advantages compared to the control group. After treatment, there was no statistically significant difference in the knee joint mechanical axis angle between the HTO-PRP group and the control group (femoral tibial angle (FTA): MD = -0.29, 95% CI (-1.07, 0.49), P = 0.47; medial proximal tibial angle (MPTA): MD = 0.19, 95% CI (-0.49, 0.88), P = 0.58; posterior tibial slope (PTS): MD = -0.12, 95% CI (-0.49, 0.25), P = 0.53; knee varus angle (KVA): MD = -0.30, 95% CI (-1.77, 1.17), P = 0.69; weight-bearing line (WBL): MD = 1.10, 95% CI (-0.89, 3.09), P = 0.28).</p><p><strong>Conclusion: </strong>The results showed that in the treatment of KOA, the HTO-PRP group had better efficacy than the control groups did and had certain safety reliability.</p>","PeriodicalId":9189,"journal":{"name":"BMC Musculoskeletal Disorders","volume":"25 1","pages":"876"},"PeriodicalIF":2.2,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11529028/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142563771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
