- Discussion:
- type of muscinous filled cyst whch is found adjacent to joint capsule or tendon sheath;
- it consist of an outer fibrous coat and an inner synovial lining and contains a clear, colorless, gelatinous fluid;
- ganglions usually occurs singly but may be multilocular;
- more common in women
-
age:
- 70% occur between the second and fourth decades
- ganglions occurring at DIP joint (
mucous cyst) are associated w/ osteoarthritis and occur at older ages;
- rarely seen in children;
- in the report by AA Wang et al (J.Hand.Surg. 2001, Vol 26-A, p 599) the authors evaluated 14 children less than 10 years of age who presented
with cysts of the hand and wrist;
- masses included 7 retinacular cysts, 5 volar wrist ganglia, and 2 dorsal wrist ganglia;
- none of the cysts were painful and 79% of the cysts resolved spontaneously within a year;
-
location:
- frequent in hand and wrist, less often in ankle, foot, and knee;
- most common soft tissue mass of hand is ganglion;
-
dorsal ganglion: 60-70% of all ganglia over scapholunate ligament;
-
volar ganglion:
- 20% of all ganglia
- most common site at volar wrist crease between the
FCR and
APL at the scaphotrapezoid joint;
-
differential dx: (see
diff dx: dorsal wrist pain);
-
Synovial Sarcoma:
-
Extra-Skeletal Chondrosarcoma:
-
AVN
- Venous Aneuysm:
- Clinical Presentation & Exam:
-
dorsal wrist pain which is made worse w/ repeated use;
- a slow growing, localized swelling, with mild aching and weakness;
- cyst is firm, smooth, rubbery, rounded, slightly flutuant, and at times tender;
- cysts will transilluminate;
- it is usually fixed but may be slightly movable if it involves tendon sheath;
- mass may become obvious w/ wrist flexion;
- palpation of cyst w/ compression may not only the extent of the cyst but also the direction of pedicle;
-
occult ganglia;
- source of similar symptoms, esp young gymnasts;
- discomfort is usually maximal in extension;
- point tenderness is directly over scapholunate interval;
- attempt to palpate mass over scapholunate w/ wrist in volar flexion;
- Radiographs:
- usually negative;
-
arthrography is usually not helpful;
- dorsal ganglions may be found w/
scapholunate diastasis;
- if this is the case, inform the patient before surgery, to that excision of the ganglion is not blamed for future instability;
- Surgical Treatment:
-
