Objective: Success of pelvic organ prolapse (POP) mesh procedures also depends on reliable anchoring systems (AS). Our primary aim was to assess the use of soft-embalmed cadavers in testing of different AS and our secondary aim was to compare extraction forces (EF) of different AS and non-absorbable suture (NAS).
Study Design: IRB approval was obtained. NAS (Ti-cron®) and different AS were attached to force-measuring instrument (Dynamometer SS25LA) and anchored to anterior longitudinal (ALL) and pectineal ligament (PL) (Protack®, Uplift®, NAS), and sacrospinous ligament (SSL) (Surelift®, Elevate PC®, NAS) of Thiel soft-embalmed cadavers. EF were measured 2-4 times in each cadaver. Data were compared using non-parametric tests. Statistical significance was set at p < 0.05.
Results: Three female cadavers (age 59, 77 and 87) were used. NAS EF were significantly higher than AS EF for ALL and SSL, but not PL. Thiel soft-embalmed cadavers proved to be useful in testing of different AS.
Conclusions: Use of soft-embalmed cadavers in testing of different AS is feasible. According to our results, the NAS provides most reliable intra-corporeal fixation. However, significant inter- and intra-subject variability indicates that results may also be dependent on the tissue properties and anchoring procedure. Further testing using soft-embalmed cadavers could help optimise mesh procedures and establish a threshold EF necessary for reliable fixation.

Background And Objective: The COVID 19 pandemic has changed the way the human anatomy is taught. A necessary shift towards online instruction, combined with a decrease in cadaver donation has resulted in the need for maximizing formalinized, soft-embalmed, computerized, and plastinated cadaver specimens. Task-oriented activities allow students to demonstrate acquired knowledge and skills.

Background And Objective: The pandemic has forced medical education to adopt online and hybrid set-ups, and this has greatly changed the way human anatomy is taught. Course-required knowledge can be accessed using raw references like original publications, collected reviews such as those found in books, as well as in shorter versions like summaries, and in online or electronic applications or software. With readily accessible online physical materials and human resources in anatomy, the value of learning by seeking out verifiable information to answer a real time query may change the current method of teaching and assessment of outcome-based learning in a heavy-recall subject such as human anatomy.

Article Synopsis
- * Fifteen participants took a pre-test and post-test, with scores improving from a mean of 5.87 to 6.87, though the improvement wasn't statistically significant.
- * Overall, participants had positive perceptions of using Thiel-embalmed cadavers, believing they enhanced their understanding and skills in MSK-UTZ and supported the idea of incorporating this method into their training.
Validity of Elastic Imaging Evaluation of Hamstring Muscles With Knee Contracture Using Ultrasound Shear Wave Elastography.

Article Synopsis
- The study aimed to assess the mechanical properties of hamstring muscles from cadaveric specimens using ultrasound shear wave elastography (SWE), particularly focusing on those with knee flexion contractures.
- Hamstring muscle samples were tested for tensile strength, measuring the shear modulus and Young's modulus through a series of experiments involving strain and load application.
- Results indicated that hamstring muscles with flexion contractures showed significantly higher Young’s and shear moduli, suggesting they are stiffer and more resistant to elongation compared to muscles without contractures.
Surgical cystectomy training using human cadavers embalmed using Thiel's method: a pilot study.
BJU Int
November 2024
Department of Urology, University of Ulm, Ulm, Germany.
Objectives: To develop the use of Thiel soft embalmed human cadavers (TeC) in open radical cystectomy (ORC) training for the first time, to investigate the effect of cadaveric training on surgical trainees' technical skills/performance and to determine how trainees perceive the use of cadaveric workshops.
Methods: A 3-day hands-on workshop was organised. Ten trainees performed ORC on five TeC, supervised by five experts.
