The H Laminectomy: Technical Description and Clinical Experience From the First 85 Patients.
Article in International journal of spine surgery, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundOver the years, lumbar laminectomy has been widely employed by spinal surgeons for many purposes throughout the spinal canal. The Misonix BoneScalpel relies on ultrasonic energy and allows the surgeon to make precise osteotomies while protecting collateral or adjacent soft tissue structures. Amplification of electric impulses allows the blade in the BoneScalpel to oscillate at very high frequencies, which thus allow it to cut bone with immense amounts of heat, which are then tempered with copious irrigation to prevent overheating. The purpose of this study is to outline and detail an innovative technique while providing insight into the technique's clinical application in a variety of spine surgeries.
methodsData were retrospectively collected from medical charts and surgical reports from February 2018 to July 2021 for each surgery in which the ultrasonic scalpel was used to perform the H laminectomy. Baseline demographic information was recorded, including age, gender, laminectomy indication, and the number of levels of laminectomy.
resultsA total of 85 patients (64 women, 21 men) were included in this study. The mean age of the patients was 63.7 years. Of those patients, 42.4% underwent H laminectomy for degenerative stenosis without instrumentation, 31.8% for degenerative stenosis with instrumentation, 9.4% for traumatic injuries, and 7.1% for revision surgery with instrumentation. Approximately 55% of patients underwent laminectomy of 2 or more levels, while the rest underwent single-level laminectomy. No patients had a dural tear or cerebrospinal fluid (CSF) leak as a result of the BoneScalpel.
conclusionsThe H laminectomy is another safe and effective way to perform a lumbar laminectomy. The technique has not been previously reported in the literature. No patients experienced a dural tear or CSF leak from the BoneScalpel using the H laminectomy technique. This technique affords the surgeon enhanced control of the dura-ligamentum interface. Even if the surgeon is not very experienced with the BoneScalpel, this technique provides an inherent safety mechanism with constant visualization/tactile feedback of the tip of the instrument and osteotome.
