1. Case Presentation
The patient, Susie, suffered from radial nerve paralysis, which resulted in a total loss of neurological control and motor function in her forelimb. Because the affected limb could not coordinate movement, the distal portion was subject to chronic friction against the ground, leading to severe tissue wear and secondary infection.
1.1 Clinical Challenges
Initially, due to the extensive functional impairment and persistent infection, the standard medical recommendation was total limb amputation. However, a complete amputation would significantly alter the dog's biomechanics and have long-term effects on its quality of life.
2. Surgical Design of the Bionic Prosthesis
To preserve Susie’s limb and restore her mobility, Dr. Wu Zhongheng elected to utilize small animal bionic prosthetic technology (ITAP).
2.1 Customized Materials and Structure
Dr. Wu designed a bespoke "super alloy" bionic prosthesis for Susie. The internal component of the prosthesis was engineered to achieve stable biological integration with the remaining bone, while the external structure was designed to mimic the supportive function of a natural limb.
3. Surgical Outcome and Recovery
The surgical procedure was performed successfully, with the super alloy prosthesis precisely anchored into the affected site. Postoperatively, Susie underwent a period of clinical observation and functional rehabilitation.
3.1 Restoration of Mobility
Follow-up records show that Susie has become proficient in using her "super alloy leg" for daily activities. Supported by the bionic prosthesis, she is no longer limited by the mobility issues caused by nerve paralysis, and the chronic wear of the distal limb has been effectively resolved.
4. Conclusion
Susie’s case illustrates the promising future of bionic surgical technology in veterinary orthopedics. For cases facing amputation due to nerve damage or severe trauma, customized super alloy bionic prostheses provide a definitive alternative that preserves limb function and enhances animal welfare.
