Synchondrosis

Dr Andrew Dixon et al.

Synchondroses are primary cartilaginous joints mainly found in the developing skeleton, but a few also persist in the mature skeleton as normal structures or as variants.

Structure

Synchondroses are cartilaginous unions between bone composed entirely of hyaline cartilage. Most exist between ossification centres of developing bones.
