Arthroscopic treatment of Palmer 1D triangular Fibrocatilagous complex lesions with knotless fixation

Abstract

Introduction: the triangular fibrocartilage complex (CFCT) maintains the stability of the distal radioulnar joint (ARCD). The radial CFCT is supplied by the anterior interosseous artery. A radial injury with distal radioulnar instability must be repaired, as well as a central injury, so that it does not continue towards the ligaments generating instability.

Materials and methods: A retrospective study were developed to analyze the surgeries performed in patients with Palmer 1D radial CFCT lesions. Eleven male patients of 32.8 years average age were studied. All the patients were strength workers and 72.7% were athletes. The average follow-up was 18.4 months.

Results: eleven patients of working age. 63.6% of skilled hands. 100% of patients presented a 1D Palmer lesion. The visual analog scale of preoperative pain was 8 and postoperative was 1. The Dash score was 85.8 preoperative and 1.18 postoperative. The May wrist score was excellent in six patients and good in five.

Conclusion: the dorsal and radiocubital ligaments are essential to maintain adequate distal radiocubital stability and that they have adequate irrigation that allows their repair, for which reason their re-clamping is indicated. The arthroscopic technique without tunnel exposed in this work allows the CFCT to be re-anchored without tunnels and complex techniques with very good results in most cases.
