A Novel TFCC Foveal Reconstruction for Chronic DRUJ Instability Using Simpler Single Limb Tendon Graft Technique

In patients with symptomatic chronic distal radio-ulnar joint instability with irreparable triangular fibrocartilage complex, reconstruction with a tendon graft is indicated. We performed a follow up study with a minimum 32-month follow up in a bid to propose an arthroscopic TFCC anatomical reconstruction technique using a single limb of tendon graft as a viable option. Between 2015-2021, eight patients with an average age of 29.5 years underwent this novel technique. The wrist range of motion, grip strength, Patient-Rated Wrist Evaluation, Quick Disabilities of the Arm, Shoulder and Hand and Mayo wrist score were used for evaluation pre-surgery and at follow-up, showing improvement with significant p-values in grip strength as compared to contralateral wrist (84% to 107%, p=0.02), PRWE (34.5 to 4.3, p = 0.01), Q-Dash (28.2 to 3.4, p=0.01) and MWS (75 to 95, p=0.01). These promising results point to the feasibility of this simple and expedient arthroscopic method.
