Arthroscopic triangular fibrocartilage complex (TFCC) repair is a standard technique to repair the peripheral tears of the TFCC. Palmer and Werner first described the TFCC. TFCC tears are a major cause of ulnar side wrist pain. Palmer classified TFCC tears as traumatic (type 1) and degenerative (type 2). Type 1 was subdivided according to the anatomic site of tissue disruption, whereas type 2 was based on the extent of the degenerative process. The acute TFCC tears result from the shear or compressive forces between the proximal carpus and the distal ulna, whereas chronic tears are the result of positive ulnar variance with or without a preceding traumatic event. We describe a method of outside-in repair using an inline 21-gauge hypodermic needle with a 2-0 PDS suture, gaining a distinct advantage of a smaller hole in the TFCC and thus rendering the repair less traumatic, safe, and reproducible for the peripheral tears.
关节镜下三角纤维软骨复合体（TFCC）修复术是修复TFCC周边撕裂的标准技术。帕尔默和维尔纳首次描述了TFCC。TFCC撕裂是尺侧腕部疼痛的主要原因。帕尔默将TFCC撕裂分为创伤性（1型）和退变性（2型）。1型根据组织破坏的解剖部位细分，而2型基于退变过程的程度。急性TFCC撕裂是由近端腕骨和尺骨远端之间的剪切力或压缩力引起的，而慢性撕裂是尺骨正变异伴或不伴有先前创伤事件的结果。我们描述了一种使用带2-0 PDS缝线的直列21号皮下注射针进行由外向内修复的方法，该方法在TFCC上形成的孔较小，具有明显优势，因此使周边撕裂的修复创伤更小、更安全且可重复。
