Background
Whether the same computer-assisted hexapod technique that works in the thigh bone also works for correcting deformity in the shin bone (tibia).
Rationale
Tibial deformities are common — they can be congenital, post-traumatic, or follow from previous fracture surgery. The shin has different anatomy from the thigh: closer nerves, closer blood vessels, less muscle to protect them.
Results
Across 13 procedures in 12 patients we achieved complete deformity correction and restored the mechanical axis in every case. There were no non-unions. The complications observed were ones we know to watch for in tibial work: a superficial wound infection, two cases of peroneal nerve palsy (one fully recovered, one partial recovery), and a tibial-artery pseudoaneurysm successfully treated with a stent.
Implications
The CHAOS in-theatre hexapod technique is reliable in tibial deformity, with the precision of a frame correction but the patient experience of an internally-fixed reconstruction.
