Ligamentous hyperlaxity and dorsal wrist ganglions.
Ganlions represent 60% of all hand and wrist masses and are a frequent presenting complaint in hand surgery clinics. Dorsal wrist ganglions are the most common ganglions seen in the upper extremity and typically arise from the scapholunate interval. These cysts are particularly common in young adults and are 3 times more common in women than in men. Despite their high prevalence, the cause of dorsal wrist ganglions is not well understood. These cysts can arise following trauma but often are considered idiopathic without any clear inciting event.
Symptomatic dorsal wrist ganglions were associated with both generalized ligamentous hyperlaxity and a positive scaphoid shift test. Although an association between wrist ganglions and ligamentous hyperlaxity does not prove causation, the possibility of the same underlying pathological entity causing both can be envisioned (ie, abnormal formation or organization of dense regular connective tissue) > from McKeon et al.; J Hand Surg 38A (2013) 138-2143.
