Tumoren distales Femur
Teenager with
knee pain. AP radiograph of the knee shows growth plate fusion and a metaphyseal lesion that is lytic and expansile in appearance with a narrow zone of transition and no associated periosteal reaction.The diagnosis was giant cell tumor.

A
biomechanical comparison between cement packing combined with extra fixation and three-dimensional printed strut-type prosthetic reconstruction for giant cell tumor of bone in distal femur. Postoperative T-SMART showed osseointegration: A a AP view of a 29 years olf male patient with GCTB. B Extended curettage, subchondral bone grafting and 3D-printed strut-type prosthetic reconstruction were performed. C T-SMART in postoperative day 1 showed interfacial gap between bone and implant (green box). D T-SMART taken at 2 years after surgery showed that excellent osseointegration
A
biomechanical comparison between cement packing combined with extra fixation and three-dimensional printed strut-type prosthetic reconstruction for giant cell tumor of bone in distal femur. Preoperative and postoperative X-ray evaluations: A a AP view of a 29 years old male patient with GCTB. B Extended curettage, cement packing, subchondral bone grafting and plate-screws fixation were performed. C A sclerotic rim occurred (green box), and an interfacial gap between bone and cement can be observed
Pitfalls in
the diagnosis of common benign bone tumours in children. Typical chondroblastoma of the distal femoral epiphysis: a Frontal X-ray of the right knee: well-defined round osteolytic lesion of the distal femoral epiphysis (arrow). b Sagittal fat-saturated proton density MRI: the lesion is well defined, mostly hyperintense, surrounded by bone oedema and an inflammatory reaction of the adjoining soft tissues. c CT of the right knee: the cortex is interrupted on the posterior border of the lesion (arrow), but no periosteal reaction is identified
