Abstract :
21 year old female came with complaints of pain
over right hip since 3 weeks which was acute in onset
gradually progressive and dull aching in character.
Examination showed there was restricted internal
rotation and abduction of right hip movements, with no
sensory or motor deficits of bilateral lower limbs. Blood
investigations showed marginally elevated erythrocyte
sedimentation rate, while the rest were within normal
limits.MRI scan of pelvis showed margin enhancing
focus at right acetabular roof region with perifocal
marrow changes. Trucut biopsy was done and showed
mildly hypercellular hyaline cartilage with lobular
arrangement and focal myxoid change permeating the
bone trabeculae and occasional peripheral aggregates of
osteoclast giant cells. She was diagnosed to have right
pelvic non metastatic chondrosarcoma and underwent
right internal hemipelvectomy (partial type 1and 2)
using 3D printed cutting jig and ECRT(extracorporeal
radiotherapy) of resected specimen with reimplantation
and fixation using custom made 3d printed plates for
posterior column, pre bent anterior column plate.
Conclusion: Despite the rarity of the condition, the
possibility of non metastatic chondrosarcoma in pelvis
should be taken into account in these circumstances.
This case shows the role of surgical resection, ECRT and
reimplantation of irradiated bone with help of 3D
printing in management and draws attention towards
early detection and definitive management with respect
to the rarity of the disease and the site of the bone
involvement
