Arthroscopic Resection of Wrist Scaphotrapeziotrapezoidal (STT) Joint Ganglia

Abstract

Background Volar wrist ganglion is the second most common wrist mass and accounts for 20% of all cases. Surgery is the gold standard for persistent and symptomatic ganglia. Arthroscopic resection has gained popularity in the past two decades. Application of this technique to ganglia in less accessible locations, such as the scaphotrapeziotrapezoidal (STT) joint, however, remains controversial. Case Description To date, no literature has described using the STT -ulnar (STT-u) and STT -radial (STT-r) joint portals for ganglionic resection. Literature Review In this report, two cases of arthroscopic ganglionic resection utilizing the STT-u and STT-r joint portals at our institution were described. Clinical Relevance Arthroscopic resection of STT joint ganglion under portal site local anesthesia is a technically feasible, safe, and effective approach. There was no recurrence observed for both cases at 50 months of follow-up.

“…More recently, the same group that pioneered arthroscopic treatment of volar cysts published the technique and a small series of scaphotrapeziotrapezoid joint (STT) cysts, demonstrating that the method is feasible and safe with good results. 14 They used specific STT portals for lesion excision, further expanding the use of arthroscopy, now for mediocarpal cysts.…”
