Background
How far the drill bit actually plunges past the far side of the bone when surgeons drill a hole during fracture surgery — and whether more experienced surgeons are any better at controlling that overshoot than less experienced ones.
Rationale
Drilling is one of the most ordinary steps in orthopaedic surgery, but on the far side of the bone there are often nerves, blood vessels and tendons. If the drill bit travels too far, those structures can be damaged. We wanted to measure, in a controlled setting, how big a problem this really is.
Results
153 surgeons and doctors at a training course each performed three drillings on artificial bone with a sensor-plate fitted on the far side. On average, the drill bit projected just over 6 mm beyond the far cortex. There was no clear improvement with seniority — trainees and experienced surgeons over-drilled by similar amounts.
Implications
This is a small but real source of unintended injury during fracture surgery. The lesson for surgeons is to drill with deliberate care — particularly in places where important nerves and vessels lie just behind the bone. For patients, the message is that complications from over-drilling are recognised, and modern technique pays close attention to managing them.
