Catheter-assisted evacuation through limited laminectomy for traumatic long-segment spinal epidural hematoma in ankylosing spondylitis: a technical note and two case reports.
Article in BMC musculoskeletal disorders, 2026. 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
backgroundPatients with ankylosing spondylitis (AS) are prone to unstable spinal fractures with long-segment spinal epidural hematoma (LSEH). Conventional multilevel laminectomy can achieve complete decompression but may disrupt the posterior tension complex. In this article, we describe a catheter-assisted technique for evacuating LSEH through a limited laminectomy window.
methodsTwo AS patients with traumatic cervicothoracic LSEH underwent emergency posterior stabilization followed by limited laminectomy. A 15 Fr silicone catheter with a distal side-hole was advanced epidurally along the hematoma through the laminectomy window. We applied alternating negative-pressure suction and intermittent saline irrigation until free backflow was achieved and dural decompression was confirmed.
resultsComplete radiographic decompression was obtained in both cases and their neurological recovery was substantial. Case 1 improved from Japanese Orthopaedic Association (JOA) score 3/17 and American Spinal Injury Association (ASIA) classification B preoperatively to JOA 16/17 and ASIA E at 6 months post operation, regaining independent ambulation. Case 2, presenting with JOA 0/17 and ASIA A pre-operation, improved to JOA 9/17 and ASIA C at final follow-up, with a recovery of deep sensation and partial motor function.
conclusionCatheter-assisted evacuation via limited laminectomy represents a feasible approach for LSEH in AS patients. This technique facilitates effective decompression while minimizing damage to posterior spinal structures.
