Use of a three-dimensional-printed spine model for surgical planning in a feline vertebral chondroblastic osteosarcoma.
Article in JFMS open reports. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Case summary: A 2-year-old, male neutered domestic shorthair cat presented with a 1-month history of non-specific pain and inappetence, left-sided Horner syndrome, pelvic limb proprioceptive ataxia, upper motor neuron paraparesis and a plantigrade stance. Advanced imaging revealed a heterogeneous contrast-enhancing extradural mass dorsal to the T1-T2 intervertebral disc space, causing severe left-sided spinal cord compression. Medical image processing software was used to generate a patient-specific three-dimensional spine model based on MRI and CT data. A biomechanical three-dimensional-printed replica of the T1-T3 region allowed preoperative simulation of a left-sided hemilaminectomy and mass removal, confirming contiguity of the lesion with the T1 vertebral body and extension along the vertebral canal to T2-T3. The model aided intraoperative landmark identification and facilitated safe and effective spinal cord decompression. Histopathology from surgical biopsy was most consistent with either chondroblastic osteosarcoma or chondrosarcoma. Postoperative radiation therapy was initiated but discontinued owing to difficulties establishing reliable intravenous access. Progressive neurologic deterioration eventually led to euthanasia. Post-mortem CT and necropsy confirmed a diagnosis of chondroblastic osteosarcoma without evidence of metastatic disease. The cat had a survival time of 356 days after surgery (387 days from initial presentation). Relevance and novel information: This report describes the first known vertebral chondroblastic osteosarcoma in a cat. It highlights the value of biomechanical three-dimensional-printed spine models for preoperative planning in complex vertebral surgery and demonstrates that tumor debulking, even when combined with incomplete radiotherapy, can provide meaningful palliation and prolonged survival. Further studies are needed to define optimal treatment strategies and prognosis for feline vertebral osteosarcoma subtypes.
