Abstract: This clinical case study details a therapeutic hoof trimming procedure for a bovine patient presenting with severe lameness and weight-bearing reluctance. Initial diagnostic observation revealed significant mechanical imbalance caused by asymmetric claw overgrowth and a necrotic secondary pathology in the dewclaw. The intervention involved systematic mechanical rebalancing of the lateral claw using an angle grinder, followed by exploratory modeling of a sole fissure. This modeling successfully identified a sub-solar abscess. Treatment included the complete debridement of the necrotic horn to facilitate drainage, application of iodine to desicate exposed sensitive laminae, and the installation of an orthopedic block on the healthy medial claw to provide mechanical offloading. Additionally, a rare ulceration of the dewclaw was debrided and bandaged. Post-procedural gait analysis confirmed an immediate improvement in the patient’s locomotive score.

Clinical Summary and Intervention Findings:

• 0:00:02 Symptomatic Presentation: The patient exhibited classic signs of lameness, including a "crooked" ankle posture (fetlock flexion) and a refusal to bear weight on the affected limb.
• 0:01:14 Mechanical Rebalancing: The lateral (outside) claw was found to be significantly longer than the medial claw. An angle grinder was utilized to reduce the entire height of the lateral sole and shorten the toe to restore functional symmetry and balance.
• 0:02:15 Diagnostic Modeling: Despite a large visible crack in the toe triangle, initial exploration suggested it was not the primary source of pain. The practitioner continued modeling toward the heel to investigate deeper pathology.
• 0:03:00 Knife Technique and Philosophy: The practitioner noted the importance of "modeling up" with a curved knife to improve tool proficiency and precision in confined hoof structures.
• 0:04:21 Identification of Sub-solar Abscess: Further reduction of the heel horn revealed a translucent area indicating a fluid-filled cavity. Bubbles and fluid discharge confirmed a pressurized abscess underneath the hoof horn.
• 0:07:20 Cavity Debridement: The wall horn and necrotic sole were carefully removed to fully expose the abscess cavity. Minor hemorrhage (the "red stuff") was noted and managed to ensure no further infection was trapped.
• 0:08:48 Therapeutic Offloading: Topical iodine was applied to the exposed tissue to aid in dehydration and disinfection. A large orthopedic block was adhered to the healthy medial claw, successfully elevating the injured lateral claw off the ground to facilitate healing.
• 0:09:03 Dewclaw Pathology: Examination of the dewclaw revealed a severe split and a protruding ulcer at the base. The presence of digital dermatitis was identified as a likely contributing factor to the ulceration.
• 0:10:31 Debridement and Bandaging: The necrotic horn of the dewclaw was removed using a grinder and knife. A therapeutic wrap was applied to secure the treatment product against the ulcer.
• 0:11:33 Post-Operative Gait Analysis: Following the application of the orthopedic block and the debridement of the abscess and dewclaw, the patient demonstrated a significant increase in comfort and a more stable, confident gait during ambulation.
