Transferencia del extensor propio del índice al pulgar: Reporte de caso

Abstract

The rupture of the extensor pollicis longus tendon is a pathology that generates disability in the interphalangeal extension of the thumb. Direct suturing in these cases can lead to suture failure. Therefore, tendinous transfer of the extensor indicis proprius is a good alternative, especially in chronic cases. There is no current data in the literature of cases that report good functional results and fewer complications of the thumb after performing the tendonous transfer in patients who suffered an injury several years ago without treatment. The importance of this case report is to provide more updated information that might be useful for future research. Objective: To report a case of tendinous transfer of the extensor indicis proprius due to rupture of the extensor pollicis longus. Case Report: A 68-year-old female patient from a rural area, a housewife, with no personal or family pathological history, was diagnosed with rupture of the extensor pollicis longus 25 years ago due to a sharp object was treated with a transfer with the extensor indicis proprius. Conclusion: The tendinous transfer of the extensor indicis proprius for the reconstruction of the extensor pollicis longus is useful to restore the functionality of the inter and metacarpophalangeal extension of the thumb, proving to be one of the most suitable and valid techniques. Adequate functional results are achieved in the short term, with quick incorporation to work tasks with low complications.
