Use of a New Microtensile Connection Energy Screening Strategy for the Look at Enamel Binding.
155 [95% CI1.114-4.168]; p = 0.023) were confirmed as independent risk factors for POUR. (Journal of Surgical Orthopaedic Advances 29(4)225-229, 2020).Current literature suggests that distal tibia Salter-Harris Type III and IV fractures with > 2 mm of displacement should be treated surgically to minimize growth arrest. The objective of the current study is to determine, in Salter-Harris Type III and IV distal tibia fractures, if gap displacements 2 mm post-surgery are associated with osteoarthritis, and to determine how often growth disturbances are observed in surgically-treated patients. A retrospective case series review of fourteen patients with displaced distal tibia Salter-Harris Type III and IV fractures was performed. The patients were evaluated using Kärrholm's method of clinical evaluation. The current study demonstrated that surgical reduction to less then 2 mm gap displacement results in fracture union in all cases, reduction to less then 2 mm does not result in osteoarthritis in any cases, and only 8% of patients demonstrated a growth disturbance with surgical intervention. (Journal of Surgical Orthopaedic Advances 29(4)219-224, 2020).Although the vast majority of arthroplasty surgeons allow patients to return to participation in golf following total knee arthroplasty (TKA) and total hip arthroplasty (THA), there is relatively little published data regarding how TKA or THA affects a patient's golfing ability. The purpose of this study was to determine how golfers' handicaps change following TKA and THA. We mailed a questionnaire to patients who had underwent primary TKA or THA at our institution and asked whether they played golf and for their golf handicap information network (GHIN) number. We then obtained handicap data for each patient that provided a GHIN number. Handicap increased 0.9 strokes 1 year following THA; however, this difference was not statistically significant (p = 0.20). Handicap increased 0.3 strokes 1 year following TKA; however, this difference was not statistically significant (p = 0.29). Our study demonstrates that despite improved implants, surgical techniques, and rehabilitation protocols that golf handicap does not change significantly following lower extremity total joint arthroplasty (TJA). (Journal of Surgical Orthopaedic Advances 29(4)216-218, 2020).The literature is scarce regarding the safety or efficacy of closed reduction attempts of acute glenohumeral fracture dislocations. The objective of this study was to assess the safety and success rate of attempted closed reduction of proximal humerus fracture dislocations. A retrospective review was performed on all proximal humerus fracture dislocations seen at one institution from 2011-2015 in order to evaluate for clinical scenarios with greater failure rates of glenohumeral fracture dislocation joint reductions by closed manipulation. The results indicate that, in general, reduction attempts are safe, but that success rates are inversely proportional to fracture severity. (Journal of Surgical Orthopaedic Advances 29(4)212-215, 2020).Cerclage fixation following intraoperative fracture of the proximal femur during total hip arthroplasty (THA) carries a risk of compromising the femoral blood supply. Thus, we sought to determine the minimum cerclage cable tension required to restore the stability of a cementless femoral stem. Cementless femoral prostheses were implanted in seven proximal femoral cadaver specimens, and a periprosthetic fracture was simulated in the medial cortex. A single cerclage cable was placed just above the lesser trochanter and tensioned and tested at increasing intervals. The implant's torsional stability was determined in the intact bone, prior to fixation, and at each level of cable tension. We found that a single cerclage cable placed above the lesser trochanter can significantly improve, but not fully restore, torsional stability following intraoperative periprosthetic femur fracture during THA. The optimal position for a single cerclage cable appears to be above the lesser trochanter.

Total Knee Arthroplasty (TKA) can have a profound impact on patients with osteoarthritis, providing them with increased quality of life, improved function, reduction of pain, while simultaneously preventing the development of additional comorbidities. Although there is inconclusive evidence that increased body mass index (BMI) is linked to increased perioperative complications among TKA patients, recent studies suggest this association exists. The aim of this study is to provide conclusive data on the effects of BMI on perioperative complications in TKA using the national risk-adjusted database, ACS-NSQIP. Our study demonstrated that there was a correlation between increased BMI and perioperative outcomes, particularly with surgical site infections, renal, and respiratory complications. (Journal of Surgical Orthopaedic Advances 29(4)205-208, 2020).Goal of the study was to determine the average noise exposure to the orthopaedic surgeon performing hip and knee arthroplasty and the benefit of customized hearing protection. Data from dosimeters (3MTM Edge 4) worn by three adult reconstruction orthopedic surgeons for a total of 27 operative day recordings was analyzed using 3MTM Detection Management Software (product version 2.7.152.0). Westone TRU custom hearing protection was used with different filters according to noise reduction rating (NRR). selleck inhibitor The overall average decibel level was 80.64 dB (73.6-87.2 dB, +/- 4.18). The peak decibel level averaged 103.66 dB (97.30-110.30, +/-3.02). The authors subjective trial of custom hearing protection determined the NRR 10 and 15 filters were most effective at noise reduction with adequate ability to communicate effectively. Our study demonstrates that the daily exposure to the total joint surgeon exceeds safe levels. (Journal of Surgical Orthopaedic Advances 29(4)202-204, 2020).
