In arthroscopic biceps tenodesis unicortical drilling of the humerus is more commonly practiced as it is considered safe to the vital structures lying posterior to the proximal humerus. Many surgeons are wary of the bi-cortical approach as it poses a risk to these vital structures. The aim of this study was to establish whether bi-cortical drilling in proximal humerus is safe or not. Our second purpose was to find a safe zone (if any) for bi-cortical drilling if bi-cortical drilling is safe.</p></div><div><h3>Methods</h3><p>This study is a descriptive study conducted on cadaveric shoulders. Bilateral shoulders and arms of ten fresh-frozen cadavers (mean age 77.7 y) were dissected. Four landmarks in the dissected humerus were identified. They were superior margin of the bicipital groove, center of the bicipital groove, upper and lower border of pectoralis major insertion. Bi-cortical trans-humeral pinning was done in the humerus at all these points so that the pin exited through the posterior cortex of the humerus. The shortest distance between the pin and the nearest vital structure namely axillary nerve, radial nerve, articular surface of the humeral head, and cephalic vein was calculated from each fixed landmark.</p></div><div><h3>Results</h3><p>We established that bi-cortical drilling in proximal humerus was safe. The safe zone established for bi-cortical biceps tenodesis is at the middle of bicipital groove, which is 18.00 ± 4.02 mm inferior to the groove’s upper border. The boundaries of the safe zone lie 9.39 mm superiorly and 9.40 mm inferiorly to the middle of the bicipital groove.</p></div><div><h3>Conclusion</h3><p>The center of the established safe zone for bi-cortical trans-humeral pinning was 18 mm inferior to the bicipital groove’s upper border.</p></div>","PeriodicalId":44283,"journal":{"name":"Asia-Pacific Journal of Sport Medicine Arthroscopy Rehabilitation and Technology","volume":"31 ","pages":"Pages 1-5"},"PeriodicalIF":2.1,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/45/11/main.PMC9841235.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9151694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the treatment strategy has not been established for patients with a neutrally-aligned osteoarthritic knee with severe joint line obliquity (JLO) owing to the combination of a valgus femur and a varus tibia; i.e., type II coronal plane alignment of the knee (CPAK). total knee arthroplasty (TKA) can be an option for CPAK type II-aligned osteoarthritis in older inactive patients. Here, we hypothesized that joint line horizontalization by femoral-varus tibial-valgus osteotomy (FVTVO), which may reduce the shear stress induced by JLO, could be a treatment option for CPAK type II-aligned osteoarthritis in young active patients who wish to return to sports (RTS) activity.

We enrolled patients who wished to RTS and who had a pre-symptom Tegner score ≥5 and had completed at least a 1-year follow-up. For FVTVO, closed-wedge DFO was performed in all femurs; both closed-wedge HTO and open-wedge HTO were used in the tibia, depending on the situation. Range of motion exercises began on the first postoperative day, and full weight-bearing was permitted 6 weeks postoperatively. Jogging was permitted 3 months postoperatively after confirming bone union, and patients could gradually return to their sports activity 6–12 months’ postoperatively. The Japanese Orthopaedic Association (JOA) score and knee flexion range were assessed preoperatively and at the last follow-up. Tegner activity scale scores were assessed presymptom, preoperatively, and at the last follow-up. The hip-knee-ankle (HKA) angle, JLO, mMPTA, and mLDFA were evaluated radiologically, and meniscal extrusions, osteoarthritic change, and/or bone marrow edema were assessed on magnetic resonance images.&lt;/p&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Results&lt;/h3&gt;&lt;p&gt;One man and two women were included in this case series.

However, evaluating the efficacy of immune checkpoint inhibitors (ICIs) is difficult because no standard in vitro assay for ICI efficacy evaluation exists. Additionally, blocking a particular immune checkpoint receptor (ICR) is insufficient to restore T cell functionality, because other ICRs still transduce inhibitory signals. Therefore, limiting inhibitory signals transduced via other ICRs is needed to more accurately assess the efficacy of ICIs targeting a particular immune checkpoint. Here, we introduce a newly developed in vitro coculture assay using human peripheral blood mononuclear cells (hPBMCs) and engineered human cancer cell lines. We enriched CD8⁺ T cells from hPBMCs of healthy donors through low-dose T cell receptor stimulation and cytokine (human IL-2 and IL-7) addition. These enriched CD8⁺ T cells were functional and expressed multiple ICRs, especially TIM-3 and TIGIT. We also established immune checkpoint ligand (ICL) knockout (KO) cancer cell lines with the CRISPR-Cas9 system. Then, we optimized the in vitro coculture assay conditions to evaluate ICI efficacy. For example, we selected the most effective anti-TIM-3 antibody through coculture of TIM-3⁺CD8⁺ T cells with PD-L1^-/-PVR^-/- cancer cells. In summary, we developed a mechanism-based in vitro coculture assay with hPBMCs and ICL KO cancer cell lines, which could be a useful tool to identify promising ICIs by providing reliable ICI efficacy information.</p>","PeriodicalId":44283,"journal":{"name":"Asia-Pacific Journal of Sport Medicine Arthroscopy Rehabilitation and Technology","volume":"6 1","pages":"2777-2789"},"PeriodicalIF":5.8,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10992221/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75653984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
