Triangular fibrocartilage (TFCC) injury is a condition that can lead to wrist instability and pain, often requiring surgical intervention to restore proper function. Vicente Catarrala's technique (2022) is widely recognized as an effective method for all arthroscopic TFCC reconstruction. However, the high cost of the materials involved can limit its applicability in certain clinical settings. This video presentation introduces a modified TFCC reconstruction technique using an autologous graft from the palmaris longus or brachioradialis tendon, which reduces costs by up to 30%, with only a 20% increase in surgical time. The purpose of this video is to demonstrate the execution of this technique and highlight its economic advantages without compromising functional outcomes.

The modified technique employs an autologous graft from the palmaris longus or brachioradialis tendon. The graft is passed around the radius through trans osseous tunnels and fixed to the ulna, also using trans osseous tunnels. Fixation is achieved with a single anchor point, simplifying the procedure compared to the original technique. The video provides a detailed step-by-step demonstration of the surgery, from graft preparation to final fixation. This modification aims to maintain wrist stability and functionality while significantly reducing the cost of materials used.

The modified technique proved effective in replicating the functional outcomes of established methods, providing adequate wrist stability and a satisfactory return to function. Although surgical time increased by approximately 20%, the cost reduction was substantial, reaching up to 30% compared to Vicente Catarrala's traditional technique. The video also emphasizes the simplicity of the modification, which eliminates the need for expensive materials or additional devices.

The modification of Vicente Catarrala's technique, which utilizes an autologous graft and a single fixation point, offers a viable and cost-effective alternative for TFCC reconstruction. While the surgical time is slightly longer, the material cost savings justify adopting this technique in scenarios where cost is a limiting factor. Moreover, the technique preserves functional efficacy, making it an attractive option for hand surgeons in various clinical contexts.

The modified TFCC reconstruction technique demonstrated in this video provides an economical and effective solution, with functional results comparable to established techniques. The significant reduction in costs, without compromising functionality, makes this approach a valuable option in resource-limited environments.
