The impact of an incorrect technique is usually not evident. Also, the instructor does not have a way to demonstrate the different levels of tension generated by different wire knotting techniques, nor their differing abilities to resist a load that a patient may apply. In this paper, a device is described that can provide real-time feedback on wire tension generated during knot tying, and how particular knots resist an applied distraction. This device has been used to deliver a live demonstration to reinforce lecture material, and in small group teaching exercises, where real-time feedback enhances skills and understanding. A stepwise training schedule for surgery residents structured as an entrustable professional activity is proposed. }, journal={Journal of Veterinary Medical Education}, author={Roe, Simon C.}, year={2023}, month={Dec} } @article{roe_2022, title={Drawing clinically relevant conclusions from biomechanical studies}, url={https://doi.org/10.1111/vsu.13738}, DOI={10.1111/vsu.13738}, journal={Veterinary Surgery}, author={Roe, Simon C.}, year={2022}, month={Jan} } @article{roe_2022, title={Prophylactic cerclage in canine total hip replacement}, volume={51}, ISSN={["1532-950X"]}, url={https://doi.org/10.1111/vsu.13779}, DOI={10.1111/vsu.13779}, abstractNote={Veterinary SurgeryVolume 51, Issue 3 p. 379-380 LETTER TO THE EDITOR Prophylactic cerclage in canine total hip replacement Simon C.

The purpose of this article is to describe our experience with a new cloud-based application known as Top Hat, which includes audience response tools in its application suite. The software was used in a multi-specialty, multi-instructor medicine and surgery course in the third year of a veterinary curriculum. In addition to standard multiple-choice and short-answer questions, Top Hat has several unique question types and methods of displaying the responses given. These include displaying free-text responses in a word cloud format and a “click-on-target” question type that allows students to indicate their response by clicking on a location within an image. Responses for this latter question type are displayed in a heat map format. A discussion tool is also available, which allows students to respond, read other students’ responses in real time, and then reply again if warranted. This feature also supports drawing-based responses. The variety of question types was very useful in keeping students engaged during teaching sessions, giving this application several advantages over systems that are limited to multiple-choice questions only. In addition, the application allowed rapid identification of areas of student knowledge and misunderstandings, which facilitated the direction of further discussion and clarification of important learning issues. }, number={1}, journal={JOURNAL OF VETERINARY MEDICAL EDUCATION}, author={Mariani, Christopher L. and Roe, Simon C.}, year={2021}, month={Feb}, pages={27–32} } @article{roe_2020, title={Plate Stress Does Not Decrease When Working Length Is Increased}, volume={9}, url={https://doi.org/10.1055/s-0040-1718418}, DOI={10.1055/s-0040-1718418}, abstractNote={I would like to comment on a statement that was made in the discussion section of the article describing a biomechanical comparison of two conical coupling plate constructs.[1] The testing model simulated a bridging plate and the authors included a discussion of working length.

We hypothesized that the rate of suture hydrolysis would vary directly with water temperature. Two absorbable monofilament 3-0 suture materials used in fish surgery, poliglecaprone (Monocryl™) and polyglyconate (Maxon™), were evaluated. The maximum tensile load (strength) was measured for suture loops ( n = 6) maintained in filtered city water for 2, 4, 6, or 8 weeks at 4, 25, or 37 °C. For Maxon™ at 4 or 25 °C, tensile strength did not decrease over time. However, for Monocryl™ at 4 °C, 2-, 4-, and 8-week loops were stronger than baseline loops. At 25 °C, tensile strength of the suture material declined after 2 weeks. Also, at 37 °C, the optimal design temperature for both suture materials, the strength of Maxon™ decreased at 6 and 8 weeks. Two 4-week loops of Monocryl™ disintegrated when handled, and after 6 and 8 weeks, all were untestable. This study confirms that absorbable sutures lose strength more slowly at ambient temperatures lower than the optimal design temperature (e.g., human body temperature) and will likely be retained longer in fishes living in waters below 25 °C. }, number={1}, journal={FACETS}, publisher={Canadian Science Publishing}, author={Cannizzo, Sarah A. and Roe, Simon C. and Harms, Craig A. and Stoskopf, Michael K.}, editor={Cooke, StevenEditor}, year={2017}, month={Mar}, pages={44–54} } @article{bosscher_tomas_roe_marcellin-little_lascelles_2017, title={Repeatability and accuracy testing of a weight distribution platform and comparison to a pressure sensitive walkway to assess static weight distribution}, volume={30}, ISSN={["0932-0814"]}, url={https://dx.doi.org/10.3415/vcot-16-09-0128}, DOI={10.3415/vcot-16-09-0128}, abstractNote={Summary}, number={2}, journal={VETERINARY AND COMPARATIVE ORTHOPAEDICS AND TRAUMATOLOGY}, publisher={Schattauer GmbH}, author={Bosscher, Georgia and Tomas, Andrea and Roe, Simon C. and Marcellin-Little, Denis J. and Lascelles, B.

These include management of anxiety disorders, facilitation of travel and veterinary examinations, and facilitation of calm behavior in hospitalized and postoperative patients. Despite the increasingly common use of trazodone in dogs, very little literature exists evaluating trazodone's efficacy against a placebo control. The aim of the study reported here was to evaluate trazodone in a randomized placebo-controlled clinical trial for use in facilitating calmness and ease of confinement in postoperative dogs. The study enrolled 29 dogs (14 in the trazodone group and 15 in the placebo group) and followed them during 4 postoperative weeks. Trazodone was well tolerated by dogs in the trazodone group. Although dogs in both groups were rated as improved on some behavioral measures, no difference was found between the trazodone and placebo groups in efficacy, with more than 70% of owners in both groups rating the test article (trazodone or placebo) as moderately or extremely helpful for facilitating both calming and crating of their dog. This observed lack of efficacy, over placebo, may be attributed to one or more of several factors that include features about the trial itself and the trial population, a caregiver or placebo-by-proxy effect, a lack of sensitive outcome measures for assessment, or a lack of true efficacy for the medication. It is concluded that future work will be needed to address these factors, and this report aims to provide not only results but lessons learned from the conduct of the described trial.}, journal={Journal of Veterinary Behavior}, publisher={Elsevier BV}, author={Gruen, Margaret E. and Roe, Simon C. and Griffith, Emily H. and Sherman, Barbara L.}, year={2017}, month={Nov}, pages={41–45} } @misc{roe_biskup_2016, title={Ability of the Tightrope((R)) and Percutaneous Lateral Fabellar Suture Techniques to Control Cranial Tibial Translation}, volume={45}, ISSN={["1532-950X"]}, DOI={10.1111/vsu.12430}, abstractNote={Objective To compare the ability of the Tightrope® (TR) cranial cruciate ligament (CCL) technique, percutaneous lateral fabella suture (pLFS) technique, and normal CCL to control cranial tibial translation (CTT).

The paper by Tyagi et al adds to our understanding of the effect of placing pins in multiple planes, using a greater number of pins, and joining the connecting bars, on frame mechanics. While the frames used were uniform, clinicians must balance the number, type, and orientation of the pins with the potential for soft tissue interference, bone damage from pin insertion, and creating a frame that is too stiff. One statement that needs clarification is the diameter of pins used in external skeletal fixation. They stated that 1– 1.6mm pins were used most commonly but the reference was a publication on circular fixators. This is not representative since the small diameter pins used in circular fixators are tensioned to increase their stiffness and the stiffness of the frame. The small diameter wires used in Tyagi’s study were not tensioned. More commonly, linear and free‐form fixators would be constructed with fewer pins but with larger diameter so that they provided adequate stiffness. It is, however, likely that the main conclusion of this study, that distributing connecting bars around the limb, and joining them together, will improve frame stiffness, is still valid for linear fixators with larger diameter pins. The intent of this letter is to discuss the methodology and how the data are reported. For each evaluation method, the authors chose to report stress, strain, modulus, and stiffness. Stiffness is relevant as it describes the response of each frame configuration to load. Surgeons are comfortable with the concept that frames with greater stiffness in their elastic region are more effective in controlling motion at the fracture site. However, the other 3 parameters are much less meaningful for this type of study. The specifics of how stress, strain, and modulus were calculated or what they identify are not included, with reference only to an engineering text. The details of the calculations would be important to allow the results to be interpreted. Stress is a method for normalizing load data to a cross sectional area so that different materials of different dimensions can be compared. It was not clear over what area the load was distributed as this could be the epoxy columns, the pins, or the fracture site. If it was the fracture site, then this has little relevance, since this is an area of a piece of plastic that happens to be the right diameter. Strain is a method for normalizing displacement based on the original length of the specimen. The original length was unclear whether it was the arbitrarily decided fracture gap or the total model length. If it was the fracture gap, the result can only be referent to 10mm as it is underdetermined if a different gap would change the result. Modulus is the ratio of stress to strain and thus is dependent on the definitions of both. In this paper, interpretation cannot be made in the absence of clear definitions of stress and strain. Engineering parameters are best used to define a material, not a construct with multiple elements and different materials. Since the frames were all constructed on the same bone model, the measured load and displacement data would be a useful way to compare frames. These responses would have more clinical relevance than stress and strain. However, for load and displacement responses to be relevant, how they are derived from the data is important. For compression testing, failure is the term used, but the definition is not provided. For bending, yield is the point of interest (which is more clinically relevant than failure), but again is not defined. In constructs of this form, there is a gradual transition from the elastic to the plastic portions of the load versus deformation curve, which makes determination of the exact yield point difficult. For torsion testing, failure is used first, but then is defined as the point at which “plastic deformation started,”which would better define yield. For mechanical studies to have clinical relevance, it is important to use data that have meaning. Common engineering parameters (stress, strain, modulus) are rarely suitable for complex biologic materials and constructs. The engineering parameters are defined assuming homogeneity and linearity, which is rarely achievable in biology. Load and deformation at yield, peak, or failure (depending on the most clinically relevant) are more meaningful parameters. Comparing structures using clinically relevant loads or deformations is also a useful approach. Stiffness is often the most relevant parameter for musculoskeletal evaluations. However, for many biologic materials, the true stiffness of the elastic region is not linear. Calculating a single value assumes linearity.

STUDY DESIGN Prospective clinical study. ANIMALS Dogs (n=35) that had THR. METHODS THR was performed using the BFX THR technique. Postoperative pain management regimens were similar for all dogs. Standing bodyweight distribution (%BW(distrib)) was measured using a pressure sensitive walkway and radiographs made before surgery and at 3, 6, and 12 months after surgery. Repeated measures models (with backwards-stepping to obtain the final model) were used for statistical analysis. RESULTS Temporally, %BW(distrib) to the operated limb increased (P<.0001; normal by 3 months) and decreased to the unoperated limb (P=.0001) and also increased to the pelvic limbs and decreased to the thoracic limbs. %BW(distrib) to the unoperated limb was significantly less than the operated limb at 3, 6, and 12 months after surgery. Postoperative canal fill and femur flare were significantly negatively correlated with change in %BW(distrib) (estimate=-0.24, P=.0413).

STUDY DESIGN Cadaveric technique development; in vivo placebo-controlled, prospective crossover study. ANIMALS Canine cadavers (n=38) and 8 clinically healthy, adult hound dogs. METHODS A technique for peripheral block of the radial, ulnar, musculocutaneous, and median nerves (RUMM block) was evaluated using cadaver limbs. Eight purpose-bred, research dogs were anesthetized; a RUMM block was performed on each thoracic limb. One limb from each dog randomly received 0.5% bupivacaine and the opposite limb was assigned to receive sterile saline solution as a control. After recovery from anesthesia, skin sensation at selected dermatomes was evaluated for 24 hours using a mechanical stimulus. Weight-bearing, conscious proprioception, and withdrawal reflex were also evaluated. One month after initial testing, each dog was reanesthetized and each limb received the opposite treatment. RESULTS Sensory thresholds were significantly increased over baseline measurements when compared with control limbs for all nerves. Complete sensory block was achieved in radial (15/16), ulnar (3/16), musculocutaneous (8/16), and median (11/16) nerves, using a mechanical stimulus of analgesia. Complete simultaneous block of all nerves was only obtained in 1 of 16 limbs. CONCLUSION RUMM block resulted in desensitization of the skin in the associated dermatomes for 4-10 hours.

Following this initial evaluation, the accuracy of high‐field MR imaging to detect meniscal tears in dogs was evaluated in 11 dogs suffering from naturally occurring cranial cruciate ligament rupture. Dogs underwent MR imaging of the affected stifle before surgery. MR imaging and surgical findings were assessed independently, and then compared. Five tears of the medial meniscus were correctly diagnosed with MR imaging and 19 normal menisci were accurately characterized as such, based on MR images. In one medial meniscus, changes consistent with meniscal degeneration were seen on MR images but this was not seen at surgery. With regard to the lateral meniscus, one false positive diagnosis of a tear was made and this likely represented a normal variation. One other lateral meniscus had changes consistent with meniscal degeneration but, as with the similar lesion seen in the medial meniscus, this was not confirmed surgically. The global sensitivity of MR imaging for the diagnosis of a meniscal tear was 100% and the specificity was 94%.

HYPOTHESIS Owner subjective assessments and an activity monitor (AM) can be used to detect pain in cats with osteoarthritis and to assess efficacy of treatments. ANIMALS Thirteen cats older than 10 years old, with owner-assessed decreases in activity, painful arthritic joints, and clinically normal blood work were included and evaluated for 3 weeks. METHODS A collar-mounted AM measured activity and a client-specific outcome measure (CSOM) questionnaire characterized the severity of impairment. Overall global quality of life was also evaluated for each treatment. In weeks 2 and 3, meloxicam (0.1 mg/kg, day 1; 0.05 mg/kg, days 2-5) or a placebo was administered in a blinded, randomized, cross-over manner to test the assessment systems. RESULTS The cats had a median of 4 arthritic appendicular joints. Activity counts for the week when cats (complete data on activity; n=9) were administered meloxicam were significantly higher than at baseline (P = .02) but not after placebo (P = .06). Baseline activity counts were not significantly different from placebo (P = .6). The CSOM data (n=13) showed that owners considered their cats to be more active on meloxicam compared with baseline (P = .001) and placebo (P < .004), and more active on placebo than at baseline (P < .01). Global quality of life improved significantly with meloxicam (P < .042).

Each cat was encouraged to walk across the walkway five times over a period of 30 to 45 minutes (by using food, toys, the owner's presence and a purpose‐built tunnel) at a target speed of 0·6 m/s (and an acceleration of less than ± 0·1 m/s2). They were then encouraged to jump on to the walkway from a height of 1 m five times at five‐minute intervals. The kinetic parameters of peak vertical force (pvf) and vertical impulse (vi) were measured for each limb (the forelimbs only for the jumps), and expressed as a percentage of bodyweight (pvf %bw and vi %bw/s). Fifteen of the 23 cats satisfactorily completed three to five walks and two to five jumps that could be analysed. There were no significant differences between the pvf or vi of the left and right limbs, but both parameters were significantly greater for the forelimbs than the hindlimbs (P<0·001) for the walking data.

Data on the mechanical properties of ewe vertebral cancellous bone is needed to assess its effectiveness as a model for vertebral osteoporosis. This study utilized traditional compression testing and a novel nondestructive vibrational testing method to assess the directional mechanical properties of ewe vertebral cancellous bone. Composition and density properties were also assessed. It was hypothesized that vibrational testing would have utility in that it would allow for the anisotropic stiffness of cancellous bone to be assessed nondestructively. The present study has found that ewe vertebral cancellous bone has similar physical and mechanical properties to humans. The vibrational testing method described was able to nondestructively provide a valid measure of stiffness that was correlated with stiffness estimates from traditional compression testing. Furthermore, the stiffness measure from the vibration test was found to be sensitive to the architecture of cancellous bone.

In vitro models were used to simulate changes observed during pin loosening in vivo. Fixation pin axial natural frequency decreased with decreasing tensile modulus of the material into which it was implanted. In a live animal study the right tibia of 12 dogs was fractured and stabilized with a four-pin unilateral external fixation frame. The axial natural frequency of each pin was measured and radiographs were taken at 0, 2, 4, 6, 8, and 10 weeks after surgery. The natural frequency did not change when the first radiographic changes around the interface were observed. Pins were palpably stable at this point. As loosening progressed, the natural frequency did decrease. Frequency and quasistatic tests of dissected pin-bone structures revealed a good correlation between natural frequency and pin-bone interface stiffness. In addition, the measurement of natural frequency was more sensitive to bone structure changes at the pin-bone interface than low-load quasi-static stiffness. Therefore, a nondestructive vibration technique could be used instead of low-load quasistatic tests for assessing the pin-bone interface ex. vivo.}, number={3}, journal={ANNALS OF BIOMEDICAL ENGINEERING}, author={Kay, MW and Roe, SC and Stikeleather, LF and Mahmoud, A and Abrams, CF}, year={1998}, pages={361–368} } @article{marti_roe_1998, title={Biomechanical comparison of the trocar tip point and the hollow ground tip point for smooth external skeletal fixation pins}, volume={27}, DOI={10.1111/j.1532-950X.1998.tb00151.x}, abstractNote={ Objective—To compare the insertional characteristics of external fixator pins with hollow ground (HG), modified HG, and trocar (T) points.}, number={5}, journal={Veterinary Surgery}, author={Marti, J.

The study of these fractures has been limited in part by the lack of a suitable laboratory model. In this study, a new cadaveric model of calcaneus fractures was developed, using a combination of osteotomies and impaction. The model allows a pattern of intraarticular injury to be reproduced consistently. The model was used to examine one aspect of internal fixation. It was hypothesized that fixation would be more stable if the screws supporting the posterior facet were incorporated into the lateral plate, as opposed to being separate from the plate. Six pairs of anatomic specimen legs were used, and each pair was divided randomly between two experimental groups. In Group A (screws out), the posterior facet screws were outside the plate, and in Group B (screws in), the screws were incorporated into the plate. The strength of the reconstructed calcanei were evaluated by axial loading of the limb through the tibia. Stiffness and energy to failure were significantly greater and Bohler's angle significantly less compromised in Group B. It was concluded that the position of the articular fragment of comminuted calcaneal fractures will be maintained at higher loads when the screws in the posterior facet are incorporated into the lateral plate.
