In plain language
In one small orthopaedic hospital with poor radiation protection practice, orthopaedic surgeons reported more cancers (29%) than other monitored staff (6%) or unexposed workers (4%). This is an association from a small, self-reported cluster study, not proof of cause.

What it found
Cumulative cancer incidence was much higher among orthopaedic surgeons than other dose-monitored workers and unexposed workers.
Key figures: 29% (9/31) vs 6% (8/125) vs 4% (7/158)
In logistic regression, working as an orthopaedic surgeon was significantly associated with increased tumour risk.
Key figures: P<0.002
The study was prompted by a cancer cluster in a small hospital with poor radiation protection practice.
Key figures: 5 cancer cases over 7 years
Limits to keep in mind
Small single-hospital study triggered by a reported cluster, with cancer occurrence obtained by questioning workers and all tumour types pooled into one category. No individual dose data are reported in the abstract and confounding cannot be excluded.
