Outcome of arthroscopic debridement for the treatment of incomplete third carpal bone slab fractures in racehorses.

Abstract: To describe the outcomes of arthroscopic debridement of third carpal bone (C3) incomplete slab fractures (ISF) in racehorses. Methods: Retrospective case study. Methods: Horses undergoing arthroscopic debridement of ISF of C3. Methods: The medical records of horses surgically treated for ISF of C3 were reviewed. Age, sex, breed, limb, fracture configuration, preoperative radiographs, arthroscopic findings, postoperative intraarticular therapies, and exercise recommendations were recorded. Racing performance was obtained from online databases. Univariable analyses were used to determine associations between independent variables and outcomes. Results: A total of 33 horses fit the criteria. There were 19 Thoroughbreds and 14 Standardbreds. The postoperative racing rate was 66.7% (22/33 horses). There was no statistically significant difference in outcome between dorsal and sagittal fractures or breeds. There were no significant differences in earnings per start or total earnings before and after surgery. Several horses showed an increase in racing frequency and an increase in earnings post-injury. Most horses, 81.8% (27/33), had at least one career start prior to undergoing surgery. The median convalescent period was 247.1 days. Conclusions: Early diagnosis and subsequent arthroscopic debridement of C3 ISF was a viable treatment approach with a favorable prognosis for racing postoperatively. Conclusions: Early detection and arthroscopic debridement of ISF before progression to a complete slab fracture and/or subsequent osteoarthritis of the joint could improve athletic outcomes.

The study discusses the effects of arthroscopic debridement for the treatment of an incomplete third carpal bone slab fractures in racehorses, revealing that early diagnosis and suitable treatment can result in a favorable prognosis for racing post operation.

Research Methodology

  • The research applied a retrospective case study where horses underwent arthroscopic debridement, a minimally invasive procedure, for third carpal bone incomplete slab fractures.
  • Data from various aspects were analyzed – age, sex, breed, limb, fracture configuration, pre and postoperative conditions corroborated with radiographs, arthroscopic findings, intraarticular therapies after surgery, and exercise recommendations.
  • The information about the racing performance of these horses was acquired from online databases.
  • To establish relationships between different variables and outcomes, univariable analyses (analysis where one single variable is studied) were used.

Results

  • A total of 33 horses qualified for the study. The breed of horses included 19 Thoroughbreds and 14 Standardbreds.
  • The rate of horses returning to racing post-operation was found to be 66.7% (22/33 horses), proving the effectiveness of the procedure.
  • An interesting discovery was that there was no significant variation in outcomes between races with dorsal and sagittal fractures, or breeds.
  • Similarly, there was no significant difference between the earnings per start or total earnings of the horses before and after surgery. Some even presented increased earnings and race frequency post-injury.
  • A majority of the horses (81.8% or 27/33) had participated in at least one race before the surgery.
  • The median period horses required to recover was around 247.1 days.

Conclusions

  • The research concludes that early diagnosis and subsequent arthroscopic debridement of an incomplete third carpal bone slab fracture is an effective treatment method, with a promising prognosis for postoperative racing.
  • Additionally, it suggested that early detection and appropriate treatment of an incomplete slab fracture could possibly prevent its progression to a complete slab fracture or subsequent osteoarthritis in the joint, thereby improving athletic outcomes for the horse.
