Proximal interphalangeal arthrodesis in seven horses: A retrospective study in Brazil (2011-2019)

Abstract

This study discussed several cases of proximal interphalangeal arthrodesis in horses at a veterinary hospital in Brazil. The medical records of seven horses that underwent proximal interphalangeal arthrodesis between 2011 and 2019 were analyzed for indication, technique, and complications. Short- and long-term outcomes were obtained from both the medical records and telephone interviews with the owners. A dynamic compression plate (DCP) was used in one of the seven horses that underwent surgical arthrodesis, and locking compression plates (LCP) were used in the others. Hospital discharge was recorded in 71.4% (5/7) of the horses, with an average hospital stay of 79 ± 45 days. Casting was maintained for 59 ± 26 days. Contact with owners was possible in four cases, two of which regained their prior level of function. The proximal interphalangeal arthrodesis may improve a horse’s well-being, especially when it is considered an early intervention, minimizing the chances of immediate postoperative complications. Additional cases of surgical arthrodesis should be evaluated in long term to better characterize the outcomes of this procedure in Brazil.

Mechanical Properties and Failure Mode of Proximal Screw Fixation Technique Using Locking Compression Plate for Proximal Interphalangeal Arthrodesis in Horses: An Ex Vivo Study

“…[12][13][14] The use of only locking screws has also been suggested for PIP arthrodesis, 4 with retrospective studies reporting the use of bicortical screws in the proximal plate hole without describing potential risks of peri-implant fractures. 15,16 In a meta-analysis, de Souza and colleagues found that 65% of horses undergoing PIP arthrodesis (using different implants) returned to their activities. 3 The authors deemed this outcome to be modest, given the treatment's potential.…”
