VCOT May 2026 – Ortho Part 1: Synovial CRP, Lumbosacral Fusion & Smarter Rehabilitation

In this Simini Small Animal Surgery Podcast episode, we begin our orthopedic coverage from the May 2026 issue of Veterinary and Comparative Orthopaedics and Traumatology (VCOT) by exploring three studies focused on making better clinical decisions through objective measurement. From synovial biomarkers for joint disease, to surgical stabilization of degenerative lumbosacral stenosis, and evidence-based rehabilitation exercises, these papers demonstrate how data—not assumptions—can improve diagnosis, surgery, and postoperative recovery.In this episode:✅ Beer et al. — Evaluated synovial fluid C-reactive protein (CRP) as a diagnostic biomarker for canine joint disease. Dogs with osteoarthritis demonstrated very low synovial CRP concentrations (median 1.2 mg/L), while dogs with immune-mediated polyarthritis (IMPA) and bacterial infective arthritis showed markedly elevated values of approximately 60–65 mg/L. Although CRP reliably distinguished non-inflammatory osteoarthritis from inflammatory joint disease, it could not differentiate septic arthritis from immune-mediated disease, reinforcing the continued importance of synovial cytology, culture, and clinical judgment when evaluating painful joints. ✅ Van der Brink et al. — Compared standalone intervertebral cages with cages combined with pedicle screw and rod fixation (PSRF) for canine degenerative lumbosacral stenosis. Both techniques achieved similar long-term clinical outcomes, with approximately 64–65% of dogs returning to full function. However, adding PSRF reduced cage subsidence from 75% to 33%, improved radiographic fusion, and decreased temporary neurologic complications by providing greater construct stability during bone healing. ✅ Ramos et al. — Used inertial motion sensors (IMUs) and surface electromyography (sEMG) to objectively measure muscle activation during rehabilitation exercises on progressively unstable platforms. While unstable "peanut" exercises increased thoracolumbar instability by 42–60%, they unexpectedly reduced activation of the epaxial muscles and biceps femoris, while dramatically increasing rectus abdominis recruitment. The findings suggest rehabilitation equipment should be selected based on which muscles require strengthening, rather than assuming greater instability universally improves core activation. Together, these studies reinforce an important clinical principle: better orthopedic outcomes come from measuring the right variables—and understanding what those measurements truly mean.🎓 Journal Articles DiscussedBeer et al. — Synovial Fluid C-Reactive Protein as a Biomarker in Osteoarthritis, Immune-Mediated Polyarthritis and Bacterial Infective Arthritis Van der Brink et al. — Comparison of Stand-Alone Cage versus Intervertebral Cage with Pedicle Screw and Rod Fixation in Dogs with Degenerative Lumbosacral StenosisRamos et al. — The Effect of Progressively Unstable Equipment Used in Canine Fitness and Rehabilitation on Standing Postural Control and Muscle Activity📚 From the May 2026 issue of VCOT🎁 Want to learn more about Simini Protect Lavage or request a sample?Learn More: www.simini.comRequest a Sample: https://www.simini.com/evaluation-kit
