Migration of an ingested orthodontic retainer into the psoas muscle presenting with radiculopathy-like symptoms: A case report.
Article in Medicine, 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
rationaleSharp foreign bodies (FBs) can occasionally perforate the gastrointestinal tract and migrate into adjacent structures, but retroperitoneal migration into the psoas muscle is exceedingly rare. Such cases may present with atypical symptoms and pose diagnostic challenges. PATIENT CONCERNS: A 26-year-old man presented with abdominal pain after swallowing an orthodontic retainer. His abdominal pain improved, but he later developed persistent right lower-limb paresthesia and aching pain that worsened with walking. DIAGNOSES: Initial computed tomography (CT) demonstrated a metallic FB penetrating a small bowel wall. A diagnostic laparoscopy performed at an outside hospital on day 3 failed to identify the FB. A follow-up CT on day 4 revealed migration of the FB into the right psoas muscle. A repeat CT performed 6 weeks later showed deeper intramuscular migration, correlating with his neurological symptoms.
interventionsA same-day urgent C-arm-assisted laparoscopic exploration was performed. After right colon mobilization and retroperitoneal exposure, the FB was localized using real-time fluoroscopy and completely removed from the psoas muscle. OUTCOMES: The patient's neurological symptoms improved immediately after surgery, and resolved at the 2-week follow-up. He remained completely asymptomatic at the 12-month postoperative follow-up. LESSONS: Psoas migration of an ingested sharp FB can occur silently without peritonitis and may present with delayed radiculopathy-like symptoms. Persistent or evolving symptoms after an initial negative exploration should prompt repeat CT imaging. C-arm-assisted laparoscopy is a feasible and effective minimally invasive approach for removing migrated retroperitoneal FBs.
