Objective：To describe clinical application of wrist arthroscopy through volar approach, and evaluate its therapeutic effects on IB, ID TFCC and dorsal radiocarpal ligament(DRCL) tear．Methods： From 2005 to 2008，13 patients suffered from IB, ID TFCC or DRCL tear were treated with arthroscopic surgery through volar approach, and assessed by the Green and O'Brien wrist scoring system．The follow-up period was about 20 months averagely. Results: Pain disappeared nearly for all patients, except for one case with mild pain occasionally． According to the Green and O'Brien wrist scoring system,  11 of 13 patients were excellent, 1 good and 1fair．Conclusions： Arthroscopic surgery through volar approach is reliable for treating dorsal wrist structures, reaching operating field quickly and safely during the operational process of IB, ID TFCC or DRCL tears.
