Objectives/Interrogation: Tendon transfer and tendon graft reconstruction are the surgical procedures used for extensive tendon injury with difficulty in repair of proximal and distal tendon ends primarily. Tendon transfer is favored by some surgeons for only one tendon repair site with less chance of tendon adhesion and tendon rupture. For multiple finger extensor tendon rupture with poor quality of proximal musculotendinous units, tendons of wrist flexor and finger flexor digitorum superficials (FDS) could be used for tendon transfer reconstruction. FDS tendon is used for finger extensor tendon reconstruction in patients of rheumatoid arthritis and radial nerve palsy. It is rare to use FDS tendon transfer in traumatic extensor tendon injury reconstruction. We will report three cases of multiple finger extensor tendon reconstruction using FDS tendon transfer in special situations.

Methods: Three patients suffered from severe multiple finger extensor tendon injury which could not be repaired primarily. The causes of injury including extensive mycobacteria tuberculosis infection and traffic accident injury. Tendon transfer reconstruction using long finger FDS tendon was performed. The donor finger FDS tendon was transferred to forearm dorsal aspect via radial side at sub-muscle fascia layer. Splint protection for 3 weeks and rehabilitation program for 2 months were undertaken after the surgery.

Resuls: The patients received regular follow up at our clinic. The patients could extend finger completely. The donor finger of FDS tendon could flex well. There were no complications during clinic follow up.

Conclusions: FDS tendon transfer could be used for multiple extensive finger extensor tendon injury reconstruction. After meticulous rehabilitation and regular follow up, the patient could have good finger extension function recovery with no obvious donor site morbidity.
