[Ultrasound-Guided Peritendinous Hydrodissection, an Alternative to Tenolysis Adhesions?]

Flexor tendon injuries of the hand treatment remains an important and common clinical problem. The rate of adhesions after flexor tendon tenorrhaphy is high. Today the treatment is surgical tenolysis, not always with satisfactory results. Ultrasound-guided hydrodissection is a novel interventional technique that consists of introducing a solution to free a compromised space or to distend and mechanically separate compressed or adhered structures. Ultrasound-guided hydrodissection is considered as an alternative to reoperation or after surgery failure. We report the first published case of ultrasound-guided peritendinous hydrodissection of adhesions after flexor tendon injury. We propose as an alternative to surgery or tenolysis, with encouraging results.
