Inevitable nonunion after ulnar shortening osteotomy in patients with ulnar impaction syndrome and breast cancer under bisphosphonate treatment.
Article in Archives of orthopaedic and trauma surgery, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundNonunion after ulnar shortening osteotomy (USO) was observed at a high rate in patients undergoing long-term bisphosphonate (BP) maintenance treatment after breast cancer surgery. Here, we report the unique features of these nonunions.
methodsIn total, 485 patients who had undergone USO between March 2008 and September 2017 were screened for inclusion based on the following criteria: (1) definitive nonunion after USO; (2) prior history of or ongoing BP therapy after the diagnosis of breast cancer; and (3) no evidence of metastasis in the ulna treated with USO, as determined based on the radiological evaluation.
resultsFive patients with histories of breast cancer and subsequent BP treatment were identified; all (100%) of these patients showed definitive nonunion after USO. The mean age was 56.2 years, and all ulnae were on the contralateral side to that of the original breast cancer. Intravenous Ibandronate
conclusionsProblems associated with BP treatment are well known. Even in cases in which the agent is essential for preventing bony metastasis of breast cancer, the normal bony physiology, including bone turnover and healing, is likely to be compromised. In addition to atypical fractures of the femur and ulna, procedures such as USO are likely to be affected by BP. Furthermore, not only a primary iliac bone graft but also other method (oblique osteotomy) should be needed to avoid nonunion during plating in USO. LEVEL OF EVIDENCE: IV, Retrospective case series.
