Summary
Objective: To describe an alternative method for the treatment of non-responsive self-mutilation
injuries in three dogs after carpal/tarsal arthrodesis. Study design: Case series Animals: Two dogs with carpal injury and one dog with tarsal injury treated by arthrodesis
Methods: All dogs developed self-mutilation injuries due to licking and/or chewing of the
toes within 21–52 days of surgery. Clinical signs did not resolve within one week
after conservative treatment with wound debridement and protective bandages. Following
general anaesthesia, a deep horseshoe-shaped skin incision, including the subdermal
tissue, was performed proximal to the selfmutilation injury transecting the sensory
cutaneous afferent nerves. The skin incision was closed with simple interrupted sutures.
Results: All wounds healed without complication. Self-mutilation resolved completely within
24 hours after surgery in all dogs. No recurrence was observed (5 months to 3 years).
Conclusion: Non-selective cutaneous sensory neurectomy may lead to resolution of self-mutilation
following arthrodesis in dogs. Clinical relevance: Failure of conservative treatment in self-mutilation injuries often leads to toe
or limb amputation as a last resort. The technique described in this case series is
a simple procedure that should be considered prior to amputation. The outcome of this
procedure in dogs self-multilating due to neurological or behavioral disturbances
unrelated to carpal or tarsal arthrodesis is not known.
