Summary
Percutaneous Endoscopically-Assisted Calcaneal Osteotomy (PECO) was found to be as safe as standard open surgery for the treatment of hindfoot malalignment in an analysis of 8 cadaver feet with less potential for cutaneous nerve injury

Abstract
Background
Calcaneal osteotomies are performed to correct hindfoot malalignment. Open surgery using traditional methods is associated with complications such as sural nerve injury and potential wound healing problems. We hypothesize that by using novel minimally invasive techniques, these potential risks could be mitigated. This anatomic cadaveric study serves to assess the safety of percutaneous endoscopically assisted calcaneal osteotomy (PECO) compared to a traditional open osteotomy technique.
Methods
Anatomic safety of PECO was assessed using 8 fresh-frozen cadaver below-knee specimens. Lateral calcaneal nerve (LCN) damage was primarily noted, and then secondly compared to a potential open surgical incision approach.
Results
In cadaver specimens, only 1/11 LCN branches (n=8 limbs) was transected using PECO, compared to up to 8/10 LCN branches (n=6 limbs) that potentially would have been injured during open surgery.
Conclusions
PECO is a minimally invasive technique that may result in fewer wound healing problems and potential neurovascular injuries relative to open procedures.
