Background
Computer-assisted external-frame surgery to correct deformity of the thigh bone — using the frame in theatre to make the correction, then fixing the bone with internal metalwork before the patient wakes up.
Rationale
Thigh-bone deformities can be correct with traditional external frame techniques, but the patient typically lives in the frame for months while the bone heals. We wanted to know if a computer-driven hexapod frame could deliver the correction in theatre, allowing immediate internal fixation and a quick exit from the frame.
Results
Across 55 procedures we achieved reliable correction of complex multi-planar deformities. The complication rate was low: two non-unions, one deep infection, one revision. There were no nerve or blood-vessel injuries and no compartment syndrome. Patients exited the frame at the end of the operation.
Implications
For thigh-bone deformity correction, the in-theatre hexapod approach is now a viable alternative to the long-term external frame. It compresses what used to take months into a single anaesthetic, with the same precision.
