This study presents a comprehensive finite element analysis (FEA) focusing on the design and material modifications of temporomandibular joint implants, with the aim of improving their long-term stability and performance. Accurate mandible models extracted from Computational Tomography (CT) scans were used to create three variations of implants, each attached using varying screw configurations ranging from 2 to 5 for each analysis. The variations included implants without dimples, implants with 10% dimples, and implants with 20% dimples. The FEA considered material properties of Titanium and Ti-Nb-Zr alloy for the implants. The FEA results revealed that for 10% dimples models, equivalent stress was reduced by 6.25% with two screws fixation and further decreased by 14.28% with three screws, irrespective of the implant volume, reaffirming the significance of screw fixation. The model secured with three screws exhibited the least amount of stress for both titanium and zirconium alloys and dimple implants showed promise in reducing stress levels, particularly in low bone density conditions. These findings not only underscore the potential advantages of dimple implants in facilitating bone in growth and stability at the bone-implant interface but also highlight the pivotal role of implant dimples in modulating stress levels. The study contributes valuable insights for future advancements in TMJ implantology, offering potential optimizations for implant design and clinical outcomes.","PeriodicalId":16125,"journal":{"name":"Journal of long-term effects of medical implants","volume":"35 2","pages":"33-39"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144013805","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}

In the present review, we discuss the predisposing risk factors, analyze the effectiveness of preventive measures, and evaluate evidence-based treatment options for surgical site infections (SSIs) in spinal instrumentation procedures. Several risk factors are identified. Preoperative factors include concomitant infections, immunocompromised host conditions, advanced age, obesity, malnutrition, uncontrolled diabetes mellitus, tobacco use, and previous spinal surgery with instrumentation. Intraoperative factors include perioperative hypothermia, prolonged duration of surgery, posterior spinal approach, and violation of sterile conditions. Postoperative factors include paralytic patient and prolonged hospital bed rest. Distinct treatment options have been devised for the management of postoperative infection without the need of removing the instrumentation. Debridement is the initial approach and antibiotic therapy is an adjunctive step. Closure of the wound after infection may be accomplished by delayed primary, secondary intention closure or by other surgical methods such as continuing suction irrigation,VAC, and hyperbaric oxygen treatment. Infections with extensive soft tissue destruction and myonecrosis are best dealt with using muscle flaps after extensive debridement. Specific measures should be taken to minimize or eliminate the risk factors and optimize the patient's condition before spinal surgery with implants. However, if infection occurs despite prophylaxis, treatment should be instituted quickly and aggressively to prevent or reduce its consequences.","PeriodicalId":16125,"journal":{"name":"Journal of long-term effects of medical implants","volume":"35 2","pages":"47-60"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144039992","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}

One time-consuming aspect of the procedure is intraoperatively measuring the helical blade length. This investigation sought to determine if preoperative imaging can be reliably used to predict helical blade length and therefore reduce operative time accurately. This was a single-center, single-surgeon retrospective chart review. All subjects were operated on by the senior author at a single urban level-1 trauma center. Each patient underwent cephalomedullary nailing using a helical blade. The medical records were reviewed for demographic, imaging, and operative data. Two raters preoperatively recorded head element length, subsequently estimated helical blade implant sizes, and actual implant length used intraoperatively. In total, 134 patients were analyzed. The results demonstrated that radiographs (R2 = 0.337, p < 0.001) and computed tomography (CT) imaging (R2 ≥ 0.435, p < 0.001) could not reliably predict helical blade length, and that radiographs were more accurate than CT scans in predicting actual implant size (p < 0.001). Preoperative imaging modalities predicted the exact size only 23.8% of the time using radiographs and 17.2% of the time using CT. Preoperative helical blade implant size was estimated accurately 24% of the time. However, raters were successful in estimating the length of the helical blade within three sizes. We demonstrate that preoperative imaging modalities are unable to accurately predict helical blade length.","PeriodicalId":16125,"journal":{"name":"Journal of long-term effects of medical implants","volume":"35 3","pages":"45-52"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144760311","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 orbit and the maxillary sinus are the most prominent parts of the face and form the most common site of fracture. Reconstruction of these frequently observed fractures is necessary. The uses of polypropylene (prolene) mesh are numerous in general surgery, so its use and effects in the maxillofacial region can be explored. The aim was to evaluate the efficacy of prolene mesh in treating defects in the midface due to trauma, especially the orbital floor and anterior wall of the maxillary sinus. This was an observational study of 15 patients with midface fractures who had undergone reconstruction with prolene mesh for orbital floor and anterior maxillary sinus wall defects. Data collected included gender, age, type of fracture, clinical parameters (e.g., postoperative tenderness at the surgical site, infraorbital paresthesia, diplopia, pus discharge, and extrusion of graft), and radiological assessment for sinus and/or orbital floor continuity and bone formation. Regular follow-ups were done at 1 week and 1, 3, and 6 months. Among the 15 patients studied, all were males with a mean age of 30 years. The clinical assessment revealed positive functional outcomes. Radiographic assessment with postoperative CT scans at 6 months showed sinus wall and/or orbital floor continuity and bone formation. The study concluded that, with proper case selection, prolene mesh is a safe and reliable option in the reconstruction of the anterior maxillary sinus wall and orbital floor.","PeriodicalId":16125,"journal":{"name":"Journal of long-term effects of medical implants","volume":"35 3","pages":"23-28"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144760321","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 goal of our study was to develop a membrane infused with carrageenan and fucoidan silica nanoparticles for guided bone regeneration around implant sites. Carrageenan (2%) was boiled for 2 min and 5% of fucoidan were added and boiled at 60°C and further 4000 μL of PEG was added, then film casting of membrane was done. 10 ml of silica nanoparticles were mixed in 0.1 g of SiO2 nanoparticles and were added to prepared carrageenan and fucoidan solution. Then film casting was done and air dried for 24 h. Antimicrobial assay, antioxidant activity, swelling and degradation analysis, FTIR test, tensile strength testing and SEM analysis were performed. The antimicrobial effect of carrageenan membrane showed better inhibitory effect against Streptococcus mutans. Antioxidant activity of the membrane infused with carrageenan and fucoidan silica nanoparticles shows 52.93 ± 0.35 SC effect percentage. The maximum force of tensile stress at break for carrageenan fucoidan incorporated with silica nanoparticles was about 5.76 MPa and for control sample membrane was 4.34 Mpa. Carrageenan and fucoidan based silica nanoparticles developed membrane showed good tensile strength and proven to have better antimicrobial, antioxidant activity with water absorption capacity which can be effectively used for guided bone regeneration around implant sites.","PeriodicalId":16125,"journal":{"name":"Journal of long-term effects of medical implants","volume":"35 2","pages":"25-32"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144007572","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}

Although the Fixion nail (Disc-O-Tech Medical Technologies Ltd., Herzliya, Israel) is an alternative technique to this method which constitutes an expandable nail, which is used to gain surgical time due to the absence of locking screws. In our department, 28 patients with tibial, femoral and humeral shaft fractures were treated by the expandable nail system for 18 months. Operative time, radiation exposure and healing time were recorded. Follow-up was obtained for a minimum of 1 year with an average of 14 months. Furthermore, in this study, we demonstrated a systematic review of the existing literature regarding the outcomes of studies on the use of the Fixion nail. In our case series, we observed one pseudarthrosis of a femoral fracture treated with a retrograde nail and two infections in tibia's fractures. In two cases, during the nail insertion, we had a failure of the implant (deformation of the tip (apex) of the nail) and two cases with delayed unions. The average operating time was 30 min (range, 26-34 min) for the tibia, 45 (range, 35-50 min) for the femur, and 20 min (range, 15-25 min) for the humerus. The radiation exposure was 0.20-0.50 s. During the systematic review, 25 studies and 790 patients with fractures of the femur, tibia and humerus were included, that met the inclusion and exclusion criteria. The mean age was 37.8 years, the time for union was 26 weeks, and 33 nonunions were observed.
