Abstract

Abstract We report a case of tibial shaft fracture after open‐wedge distal tibial tuberosity osteotomy (OWDTO). The use of a lag screw for a lateral hinge fracture in OWDTO requires careful postoperative rehabilitation and follow‐up. We discuss concerns related to the mechanical strength at the osteotomy site after OWDTO to prevent fracture.

Abstract

Abstract This report presents a case of deep peroneal nerve palsy caused by an injury during drilling for distal locking screws of a T‐shaped locking plate used for osteosynthesis of medial open‐wedge high tibial osteotomy. A cadaveric simulation study reproduced the risk of injury during the surgery.

Abstract

This report presents a case of deep peroneal nerve palsy caused by an injury during drilling for distal locking screws of a T‐shaped locking plate used for osteosynthesis of medial open‐wedge high tibial osteotomy. A cadaveric simulation study reproduced the risk of injury during the surgery., Surgeons should acknowledge the hidden risk of injury of the deep peroneal nerve when drilling for the distal locking screws during medial open‐wedge high tibial osteotomy and avoid drilling too deeply after penetrating the lateral cortex or consider a monocortical fixation fashion.
