Popis: To present the outcomes of arthroscopic electrothermal shrinkage for partial scapholunate (SL) ligament tears, isolated or with associated triangular fibrocartilage complex (TFCC) injuries. A prospective study of 20 patients with symptomatic instability of SL ligament (14 of them also with TFCC wrist injuries) treated with arthroscopic electrothermal shrinkage was conducted using a monopolar radiofrequency probe. No patient showed radiologic signs of static dissociation (mean SL interval 2.2 ± 0.6 mm; mean SL angle 41.4° ± 6.7°) before surgery. All patients underwent follow-up at our clinic regularly for an average of 50.6 months (range 29–80 months). The modified Mayo wrist score improved from a mean of 59 ± 17.1 points preoperatively to 88.3 ± 16.2 points at the final follow-up. At the final clinical examination, a painful Watson scaphoid shift test was found in 3 patients (15%). The mean flexion–extension arc was unchanged (132° ± 19°), and mean grip strength improved 12 kg. No patient showed radiologic signs of arthritis or instability after surgery (mean SL interval 1.9 ± 0.7 mm; mean SL angle 42.7° ± 7.3°). Of the 14 patients with combined TFCC injuries, 3 patients continued complaining of ulnar-sided point tenderness. At the end of the follow-up, 80% of the subjects were satisfied or very satisfied. SL ligament and TFCC electrothermal shrinkage effectively provided pain relief and grip strength increase for most of the patients treated. Level IV.
