Analysis of the clinical efficacy of arthroscopy-assisted transosseous repair of chronic triangular fibrocartilage complex foveal tears
Objective To investigate the feasibility and efficacy of arthroscopy-assisted transosseous repair for chronic triangular fibrocartilage complex(TFCC)foveal tears.Methods From March 2018 to September 2022,our department used wrist arthroscopy to repair chronic TFCC foveal tears in 9 patients with a disease course of more than 6 months.During the surgery,for combined Palmer 1A or 1D type injuries,a planer was used to clean the edges and then plasma electrocoagulation was performed for thermal shrinkage.The postoperative follow-up was conducted regularly.The VAS score,PRWE score,active motion and grip strength was set as evaluation indicators.The last follow-up results were compared with preoperative results.Results All 9 patients were follow-up for a period of 12 to 36 months,with an average of(25.0±8.3)months.At the last follow-up,VAS score,PRWE score,grip strength,and forearm rotation all improved compared to preoperative,and the differences were statistically significant.The wrist joint flexion and extension slightly decreased compared to preoperative,but the difference was not statistically significant.There were no unstable distal radioulnar joints or surgical related complications.Conclusion For TFCC foveal tears with a disease course greater than 6 months,when the quality of TFCC is good on microscopic examination,careful cleaning of the tear end during surgery and direct bone suture repair can still restore the stability of the distal radioulnar joint,achieving satisfactory clinical efficacy.
