After Fixation and bone graft
Xrays show a lytic, slightly expansile lesion of the proximal phalanx of the ring finger. A pathylogical fracture has taken place through the lesion.
It is the most common primary tumor in the hand and is normally found in the diaphysis. The mature hyaline cartilage located centrally within short tubular bones usually presents clinically as a fracture due to an enlarging lesion. Enchondromas are also found incidentally in long bones and undergo malignant transformation in less than 1% of cases.
In larger lesions, the lucent defect has endosteal scalloping and the cortex is expanded and thinned. Calcifications throughout the lesion can range from punctate to rings
Treatment given
Curettage, bone graft and internal fixation with the plate shown.
