[Selective ultrasound-guided hydrodissection of gastrocnemius nerve branch after post-surgical entrapment: Apropos of a case].

Chronic or recalcitrant plantar fasciitis is a cause of persistent plantar pain. These cases are usually resistant to conventional treatments consisting of exercises, orthoses, shock waves and infiltrations and require a surgical approach. Proximal medial gastrocnemius release is a surgical option that provides satisfactory results, but is not free of complications, which include injuries and nerve entrapment. We report the first published case of symptomatic medial gastrocnemius branch entrapment in the post-surgical scar of a tenotomy for the treatment of recalcitrant plantar fasciitis. We propose ultrasound-guided hydrodissection with local anesthetic as a treatment with promising results.
