With surgical education moving from a time-based to a competency-based model, developing high-fidelity simulation models has become a priority. The Thiel cadaveric model has previously been used for a number of medical and surgical simulations, including microvascular simulation. We aim to investigate the use of the Thiel model in peripheral nerve simulation and validate a novel evaluation instrument. Sixteen residents ranging from postgraduate years 1 to 6 participated in the study. Their nerve coaptations using Thiel cadaveric nerves were video recorded and evaluated by 5 fellowship-trained microsurgeons using the Micro-Neurorrhaphy Evaluation Scale (MNES). The intraclass correlation among the 5 evaluators was 0.75, revealing excellent interrater reliability. The Cronbach α was .77, underlining the internal consistency of the test items. Bivariate analysis revealed a significant association between the MNES scores and the participants' self-declared level of experience. This correlation was confirmed by mixed modeling. Our results validate the MNES and underscore the utility of the Thiel nerve tissue for peripheral nerve surgical simulation.

Background: In reverse total shoulder arthroplasty, a humeral osteotomy is typically performed at the anatomic neck. The quality and quantity of cancellous and cortical bone impacts sizing of implants. Little-to-no information exists characterizing the transition of this bone quality at this location.

Introduction: A proximal obturator nerve block has a similar block efficacy as the distal obturator nerve block. Previous cadaveric investigation injecting methylene blue dye solution and an immediate dissection proved the solution engulfing the anterior and posterior divisions of the obturator nerve as they emerge from the obturator canal. Uptake of methylene blue dye by the fascia and muscles obscures the exact delineation of the stained nerves.

Purpose: To compare the load distributed to the medial tibial articular cartilage after refixation of posterior medial meniscus root tears between the suture anchor and transtibial pullout techniques in posterior medial meniscus root tears.
Methods: Twelve Thiel's embalmed human cadaveric knees are used and divided into three groups (four knees in each group): (1) intact meniscus (IM), (2) fixation with suture anchor technique (SA) and (3) fixation with transtibial pullout technique (TP). Each group applies an axial compression load up to 1500 N by Instron E 10000 at two knee flexion angles (0° and 60°).
Article Synopsis
- - The study evaluated how the position of bone tunnels affects the migration of sutures used to repair medial meniscus posterior root tears (MMPRTs) in cadaveric knees.
- - Researchers created three types of bone tunnels (anatomical, anterior, posterior) and measured changes in suture length as the knee flexed from 0° to 120°, finding significant differences in displacement based on tunnel position.
- - Results indicated that sutures moved less when the tunnel was posterior (1.17 mm), compared to larger movements with anatomical (5.17 mm) and anterior tunnels (7.50 mm), suggesting optimal suture stability is achieved with posterior tunnel placement.
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.
