Degenerative lumbar spinal stenosis with osteoporotic vertebral fracture involving endplate: a retrospective study.
Article in BMC surgery, 2025. 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
objectiveDegenerative lumbar spinal stenosis (LSS) accompanied by osteoporotic vertebral fractures (OVFs) involving the endplate is relatively uncommon and presents therapeutic challenges. This study aims to evaluate the clinical outcomes of surgical treatment in such cases.
methodsA retrospective analysis was conducted on nine patients diagnosed with LSS and endplate-involved OVFs who underwent surgery at Ruijin Hospital between July 2015 and December 2022. Patients received either decompression with kyphoplasty or fusion with kyphoplasty. All patients were followed for a minimum of 12 months. Clinical outcomes were assessed using the Visual Analog Scale (VAS) and Japanese Orthopaedic Association (JOA) scores. Radiographic evaluations, including X-rays and CT scans, were used to assess implant stability, cage subsidence, and fusion status.
resultsThe study included 1 male and 8 female patients, aged 72 to 81 years (mean: 76.3 ± 5.2 years). Two patients underwent decompression and kyphoplasty, six underwent fusion and kyphoplasty, and one patient received posterolateral fusion and kyphoplasty due to an enlarged disc space and cage instability. Significant postoperative improvements in VAS and JOA scores were observed and maintained throughout the follow-up period. Radiological follow-up exceeding 12 months revealed no intervertebral height loss or segmental instability in patients who underwent decompression and kyphoplasty. All patients in the fusion group achieved successful fusion without notable complications such as implant loosening or cage subsidence. The patient who underwent posterolateral fusion also experienced no complications, including screw loosening, vertebral height loss, or hardware failure.
conclusionDegenerative LSS combined with OVF involving the endplate is a complex clinical condition. Both decompression with kyphoplasty and fusion with kyphoplasty are effective surgical strategies, providing significant and sustained clinical improvement.
