Acute rib fracture caused by preoperative positioning for direct lateral interbody fusion: A case report.
Article in Medicine, 2019. 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
rationaleDegenerative spondylolisthesis is defined as forward slippage of a vertebra with respect to the underlying vertebra and is associated with the induction of lumbar canal stenosis. The use of anterior column support for degenerative lumbar conditions has been well documented. Direct lateral interbody fusion (DLIF) gains access via a lateral approach through the retroperitoneal fat and psoas muscle. It avoids many of the access-related complications yet comes with its own risks and limitations. The location of the iliac wing precludes exposure of the L5-S1 disc space and may make L4-5 surgery difficult. Therefore, accurate preoperative patient positioning is essential. PATIENT CONCERNS: A 71-year-old female with a body mass index (BMI) of 39.2 kg/m (height 155.9 cm, weight 79.5 kg) presented with lumbar pain radiating to the left lower limb. She complained of neurologic claudication with more than 100 m ambulation. DIAGNOSIS: Plain standing view on spine radiography revealed L4-5 spondylolisthesis and disc-space narrowing. Magnetic resonance imaging (MRI) revealed severe L4-5 bilateral foraminal stenosis. After the first surgery, simple rib cage radiography was performed to examine the source of her right-sided flank pain and it revealed acute fracture of the right ninth and tenth ribs.
interventionsThe patient was laterally positioned on the table in an extreme bending position. The intervertebral cage was inserted in the L4-5 disc space and disc height was restored. With respect to the rib fracture, treatment was conservative. OUTCOMES: The patient's radiating pain was immediately relieved and her lower back pain disappeared at 3 months after surgery. The patient reported right-sided flank pain after the first surgery. Simple rib cage radiography was performed and revealed fracture of the right ninth and tenth ribs. Follow-up assessments conducted 2 months later revealed complete bony union. LESSONS: DLIF avoids many access-related complications. However, it is associated with other intraoperative complications, including injury to the lumbar nerve root and plexus. In addition, there are preoperative complications associated with improper patient placement on the table. In this case, the patient's obesity and strict positional requirements resulted in rib fracture. We suggest that surgeons consider this complication and exercise care in preoperative positioning.
