Effects of analgesia of the distal interphalangeal joint or palmar digital nerves on lameness caused by solar pain in horses.
Abstract: To determine if pain of the dorsal margin of the sole in horses can be attenuated by anesthesia of either the distal interphalangeal (DIP) joint or the palmar digital (PD) nerves. Methods: A unilateral forelimb lameness was induced by creating solar pain. Response to administration of local anesthetic or saline solution into the DIP joint and to administration of local anesthetic around the PD nerves was evaluated. Methods: Six horses. Methods: Lameness was induced by creating pressure on the dorsal margin of the sole by screwing set-screws into a nut welded to the inside of each branch of a shoe. Gaits were evaluated before and after application of set-screws and after a local anesthetic or saline solution was administered into the DIP joint and, in a second trial, after a local anesthetic was injected around the PD nerves. Gaits recorded on videotape were evaluated, and lameness scores were assigned to each gait. Results: Lameness scores were high after application of set-screws and remained high after saline solution was administered into the DIP joint. Scores decreased significantly (P < or = .05) after a local anesthetic was administered into the DIP joint or around the PD nerves. Conclusions: Analgesia of the DIP joint or the PD nerves desensitizes at least a portion of the sole. Conclusions: Pain arising from the sole should not be excluded as a cause of lameness when lameness is attenuated by analgesia of the DIP joint or PD nerves.

The research article discusses the results of a study investigating the ability of local anesthesia applied to either the distal interphalangeal joint or palmar digital nerves to relieve lameness in horses caused by pain in the sole of the foot.
Methods
- The study included six horses, in which lameness was artificially induced by applying pressure to the sole.
- This pressure was created using set-screws fixed to a shoe, which created pain along the dorsal margin of the sole.
- The horses’ gaits were assessed before the application of the screws, after the screws were applied, and after anesthetics or a saline solution was given.
- The assessment involved videotaping the horses’ gaits and assigning lameness scores based on the observed movement.
Results
- The lameness scores rose significantly after the application of the set-screws, indicating successful induction of lameness due to pain.
- The administration of a saline solution into the distal interphalangeal joint did not reduce the lameness scores, indicating no pain relief.
- Local anesthetics administered into the distal interphalangeal joint or around the palmar digital nerves significantly reduced lameness scores (P ≤ .05).
Conclusions
- These results suggest that anesthesia of the distal interphalangeal joint or palmar digital nerves can relieve at least part of the pain or discomfort arising from the sole.
- This finding also highlights the importance of considering sole pain as a potential cause of lameness in horses, especially in cases where lameness is alleviated by anesthesia of the distal interphalangeal joint or palmar digital nerves.
