[Therapy of triangular fibrocartilage complex lesions]

The triangular fibrocartilage complex (TFCC) represents an important anatomical structure interposed between the ulnar carpus and the distal ulnar. Injuries and degenerative changes of the TFCC are of high clinical relevance and there are numerous treatment options available based on different concepts and which are being used to varying extents. The aim of this systematic review was to evaluate the effectiveness of different therapies for lesions of the TFCC. Studies on TFCC lesions were systematically reviewed, classified into evidence levels and selected according to predefined criteria. A total of 259 publications were identified as being potentially relevant and finally 35 studies could be included in the review. In addition, a survey was performed among German hand surgeons in order to identify commonly used procedures for TFCC lesions in Germany. The classification of Palmer is mostly used both in the literature and in Germany and therapeutic decisions are predominantly based on this classification. The systematic review revealed some common treatment strategies for traumatic and degenerative lesions. Generally, the level of evidence was poor for all identified publications. For this reason, evidence-based recommendations for the treatment of TFCC lesions could not be derived from the literature. There was broad consent between the results of the literature review and the survey.
