Although minimally invasive surgical (MIS) techniques offer potential benefits such as reduced soft tissue trauma and faster recovery, concerns persist regarding the risk of iatrogenic injury to the sural nerve because of limited visualization. This cadaveric study aims to provide a detailed anatomical assessment of the sural nerve and its branches in relation to the entry point of the MIS Zadek osteotomy, with the goal of quantifying their proximity and offering data that may help reduce the risk of nerve injury during the procedure.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Twenty fresh-frozen human lower limb specimens were subjected to a standardized MIS Zadek osteotomy using a 3\u2009\u00d7\u200930-mm Shannon burr. The osteotomy was guided fluoroscopically and performed through a lateral percutaneous approach. Post-procedure, meticulous anatomical dissections were conducted to identify the sural nerve and measure its distance from the anterior and posterior arms of the osteotomy using digital calipers with 0.1-mm precision. Measurements were independently recorded by 2 observers to ensure accuracy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The sural nerve was successfully identified in all specimens. No instances of sural nerve transection or gross anatomical disruption were observed. The mean distance from the osteotomy to the sural nerve was 11.95\u2009mm, with a range of 8.3 to 15.4\u2009mm and an SD of 2.18\u2009mm. These findings suggest that when performed within the defined anatomical parameters, the MIS Zadek osteotomy maintains a safe distance from the sural nerve.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>In our cadaver study, we found that the MIS Zadek osteotomy maintained a mean distance of 11.95\u2009mm from the sural nerve.
