Therapeutic Intervention and Rehabilitation

On January 16, 2025, the orthosis was applied for the first time. Layla tolerated the device without attempting removal, though gait analysis revealed a decreased swing phase and reduced shoulder extension during acclimation. The rehabilitation protocol concentrated on strengthening the right forelimb musculature, passive range-of-motion exercises targeting the carpus and MCP joints, and proprioceptive activities using balance pads and low obstacles. Controlled, short leash walks were introduced progressively.

Follow-Up and Outcomes

At the first recheck on January 29, 2025, Layla had worn the orthosis indoors for 10–15 minutes daily. The owner reported difficulty seating the paw component and mild discomfort at the palmar carpus upon flexion. Adjustments were made to the strap tension and application technique. By the second recheck on February 11, 2025, a dorsomedial carpal abrasion was observed, likely due to folded padding or device slippage. A thin layer of veterinary wrap applied beneath the orthosis and instruction to tighten straps after initial wear effectively resolved the issue.

On March 11, 2025, Layla demonstrated confident use of the limb on 20-minute outdoor walks. The orthosis provided stable support without impeding gait, although occasional extrusion of the fifth digit occurred; this issue improved with routine nail trims and reinforcement of proper donning technique. Throughout the follow-up period, owner satisfaction remained high (8/10), highlighting the device’s positive impact on mobility and comfort.

As use in rehabilitation therapy continues, it was noted that the token being used (60-195) allowed the ability for carpal flexion that was impinging on the accessory carpal pad, so a new range was ordered (90-185) and was also sent an additional custom token (75-185) to test also. 

Discussion

This case illustrates the practical benefits of custom 3D-printed orthoses for canine MCP joint degeneration. Layla’s early gait adaptations were resolved with integration exercises, and minor complications were readily managed through straightforward adjustments. Regular rechecks facilitated iterative refinements to fit and function, underscoring the critical role of owner education and close monitoring during orthotic integration. The combination of mechanical stabilization, modified allowed range of motion, and tailored rehabilitation enabled Layla to resume functional ambulation with reduced discomfort.

Conclusion

Custom additive-manufactured orthoses, such as the WIMBA Carpus Orthosis Pro with Paw Component, represent a valuable adjunctive strategy for managing degenerative MCP joint disease in dogs. When incorporated into a comprehensive rehabilitation program and supported by vigilant follow-up, these devices can preserve limb function, alleviate discomfort, and potentially diminish reliance on pharmacologic treatments. Further studies should explore long-term outcomes, refine design features, and quantify functional improvements across larger patient cohorts.
