Results after arthroscopic treatment of central traumatic lesions of the triangular fibrocartilage complex
Injuries of the triangular fibrocartilage complex (TFCC) are of high clinical relevance; however, the clinical evidence for treatment is poor and long-term results are rarely published. The purpose of this study was to evaluate the clinical outcome of symptomatic central traumatic lesions of the TFCC (Palmer 1A) following arthroscopic debridement.
Materials and methods
Between 2007 and 2013, 87 patients were arthroscopically diagnosed with Palmer 1A lesion and accordingly treated with debridement. Follow-up was available for 43 patients. Activities of daily living (ADLs) were measured with the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire. Pain perception was evaluated with visual analogue scale (VAS 0–10). Grip strength and wrist motion were assessed with conventional techniques using a Jamar dynamometer and a goniometer. Patient satisfaction was assessed using a questionnaire at follow-up.
Mean follow-up was 42.5 months (range 5–70). The mean age of the patients (22 male and 21 female) at time of surgery was 41 ± 15.9 years. No major complication occurred during surgery and follow-up. The DASH score (preoperatively 49.8 ± 19.3 vs. postoperatively 14.1 ± 17.9, p < 0.05) and pain perception (VAS: preoperatively 7.2 ± 2.0 vs. postoperatively 1.4 ± 1.6, p < 0.05) improved significantly. Grip strength was satisfactory after surgery (19.6 ± 13.1). Ulnar deviation improved significantly from 29.3 ± 10.4° to 35.6 ± 8.3° (p < 0.05) and wrist flexion improved from 53.8 ± 18.9° to 67.4 ± 12.9° (p < 0.05). Wrist extension, radial deviation, pronation and supination did not change significantly after surgery. Improved symptoms were reported by 41/43 (95.3%) patients and 40/43 (93%) patients would have had the same procedure again knowing the final outcome. Six of 43 patients (15%) had an ulnar plus variance. None of these needed ulnar shortening.
Central traumatic TFCC lesions can safely be treated by arthroscopic debridement. We showed a sustained pain relief with significantly improved quality of life (DASH score) and wrist motion at follow-up. This resulted in a high patient satisfaction and acceptance of the procedure.
