Overview
Historical Perspective
- In 1928 Carp and Stout wrote a complete discussion on the genesis of the "simple" ganglion.
- In 1931 King proposed an intriguing hypothesis suggesting that the development of a ganglion was not attributed to degenerative processes but rather to the primitive mucoid secretion of connective tissue cells.
- Fairbank and Lloyd (1934), Ghormlev and Duckerty (1943), and Watson Jones (1948) have documented the reports of erosion of the tibial head by cysts originating from the semilunar cartilages.
- In 1949, Geoffrey R. Fisk introduced a description of an intraosseous ganglion in the distal end tibia.
- In 1956, Hicks introduced the term "synovial bone cysts" to characterize radiolucencies bordered by sclerotic margins within bones.
- In 1966, Crabbe coined the term "intraosseous ganglion" to describe a similar phenomenon.
- Other interchangeable terms for these entities include ganglionic cystic defect of bone, subchondral bone cyst, and juxta-articular bone cyst.
Classification
There are two primary types of intraosseous ganglion cysts:
- one arises from the infiltration of an extraosseous ganglion into the underlying bone,
- the other type is idiopathic in nature.
