Background
How often a small superficial nerve in the lower leg, which gives feeling to the front of the foot, gets caught up against the plate when surgeons fix an outer-ankle fracture using a minimally invasive technique — sliding the plate under the skin through small cuts rather than a long open incision.
Rationale
Minimally invasive plating reduces wound problems but trades a long visible incision for a longer reach under the skin. That reach can stretch the nerve or trap it against the plate. Knowing how often this happens, and whether plate length matters, helps surgeons decide which patients suit the technique.
Results
Across 20 cadaveric legs with two plates inserted in each, the superficial peroneal nerve sat in direct contact with the longer (10-hole) plate in 11 of 20 legs — over half. With the shorter (6-hole) plate, the nerve was in contact with the plate in only one of 20 cases. The difference was statistically significant.
Implications
Minimally invasive plating is a good technique, but the longer the plate, the higher the chance of trapping a small nerve against it. Surgeons should mark the planned incisions on the skin, dissect carefully down to bone, and lift the soft tissue away from the plate’s path — particularly when a longer plate is needed.
