Objective: To observe the therapeutic effect and safety of using the hooked needle-shaped knife to treat the stenosing tenovaginitis of flexor digitorum.
Methods: Sixty outpatients were divided into a treatment group of 30 cases treated by using the hooked needle-shaped knife, and a control group of 30 cases treated by block therapy. 6 months later, the alleviation of pain in the affected finger during movement, under pressure, traction and finger-bending anti-resistance was compared before and after treatment.
Results: The alleviation of pain during movement, under pressure, traction and finger-bending anti-resistance was much better in the treatment group than that of the control group (P < 0.01), with a effective rate of 93.3% in the treatment group and 80.0% in the control group (P < 0.01).
Conclusion: The micro-wound technique using the hooked needle-shaped knife has definite effect and safety for stenosing tenovaginitis of flexor digitorum.
