Treatment of flexor tendon reconstruction failures: multicentric experience with Brunelli active tendon implant

Introduction Secondary repair of flexor tendon injuries remain a challenging procedure for hand surgeons. Usually, secondary reconstruction should be performed by staged approach. When the tendon and pulley integrity are intact, tenolysis may be the first surgical option. One-/two-stage tendon grafts are suggested when the integrity of flexor tendon is compromised. Active tendon implants (Brunelli prostheses) may represent an efficient option in patients with a poor prognosis, as well as whenever classical techniques fail. Due to lack of literature about this second-line treatment, the authors present the experience of two different orthopedic departments with the permanent active tendon implant.
