Although Palmer's classification of TFCC lesions differentiates post-traumatic central perforations (IA tears) from degenerative tears secondary to ulnocarpal impaction (IIC), the distinction is not always clear clinically. In the final analysis, the literature suggests that as many as 25% of wrists with TFCC tears have residual symptoms following arthroscopic debridement alone, and it is likely that static or dynamic ulnar positive variance plays a role. The authors' results suggest that combined arthroscopic TFCC debridement and wafer resection are feasible and efficacious as treatment for all stages of ulnar impaction syndrome. When class II A and B changes are observed, that is, when a TFCC perforation has not yet developed, the authors have observed favorable results in most patients following arthroscopic TFCC central disc excision and wafer resection as an alternative to ulnar shortening osteotomy or open wafer excision.
