Clinical use of computer-assisted orthopedic surgery in horses.

Abstract: To describe clinical applications of computer-assisted orthopedic surgery (CAOS) in horses with a navigation system coupled with a cone beam computed tomography unit. Methods: Retrospective clinical case series. Methods: Thirteen adult horses surgically treated with CAOS. Methods: Medical records were searched for horses that underwent CAOS between 2016 and 2019. Data retrieved included signalment, diagnosis, lameness grade prior to surgery, surgical technique and complications, anesthesia and surgery time, and information pertaining to the perioperative case management and outcome. Results: In 10 cases, surgical implants were placed in the proximal phalanx, third metatarsal bone, ulna, or medial femoral condyle. In one case, navigated transarticular drilling was performed to promote ankylosis of the distal tarsal joints. In another case, an articular fragment of the middle phalanx was removed with the help of CAOS guidance. In the final case, a focal osteolytic lesion of the calcaneal tuber was curetted with the aid of CAOS. In seven cases, a purpose-built frame was used for the surgical procedure. All surgeries were performed successfully and according to the preoperative plan. Conclusions: Computer-assisted orthopedic surgery can be an integral part of the clinical case management in equine surgery. To optimize workflow and time-efficiency, the authors recommend designating one team for operative planning and another for the execution of the surgical plan. Specialized equipment, such as the purpose-built frame, will further improve CAOS applications in equine surgery. Conclusions: After they have become familiar with the operational principles, equine surgeons can readily apply CAOS for a broad spectrum of indications.

The research article is a study of the application and success of computer-assisted orthopedic surgery (CAOS) in horses, and it suggests that CAOS can be an important part of clinical case management in equine surgery.

Study Design and Methodology

  • The researchers conducted a retrospective clinical case series study reviewing medical records of 13 adult horses that had undergone CAOS between 2016 and 2019.
  • Data evaluated included the horse’s signalment (age, breed, sex), the diagnosis, the degree of lameness prior to surgery, the exact surgical technique used and any complications, the time of anesthesia and surgery, and information about pre and postoperative case management and outcome.

Results of the Study

  • The study found that in ten cases, surgical implants were placed in various locations such as the proximal phalanx, third metatarsal bone, ulna or the medial femoral condyle using CAOS.
  • In one case, navigated transarticular drilling was done to promote ankylosis (joint fusion) of the distal tarsal joints.
  • In another case, an articular fragment of the middle phalanx was removed with the help of CAOS guidance.
  • In the last case, a focal osteolytic lesion of the calcaneal tuber (a bone abnormality) was curetted (scraped) using CAOS.
  • In seven of these cases, a purpose-built frame was used for the surgical procedure. This specialized piece of equipment is designed to aid the use of CAOS.
  • All surgeries were performed successfully and were conducted according to the preoperative plan indicating a high degree of accuracy of CAOS.

Conclusions and Recommendations

  • The study concludes that CAOS can be a critical component in the clinical case management of equine orthopedic surgery.
  • The authors recommend designating one team for operative planning and another for the execution of the surgical plan to optimize workflow and time-efficiency.
  • The researchers also believe using specialized equipment, like the purpose-built frame, can greatly improve CAOS applications in equine surgery.
  • The authors conclude that once equine surgeons have familiarized themselves with the operational principles of CAOS, they can apply it for a wide range of orthopedic applications.
