Percutaneous plantar fascia release with needle is a novel procedure for the treatment of plantar fasciitis. The objective of this cadaveric study is to perform an anatomic evaluation of the percutaneous plantar fascia release method using a conventional hypodermic needle. In this study, we used 14 fresh-frozen cadaveric trans-tibial amputation specimens. Percutaneous plantar fasciotomy with a conventional hypodermic needle was performed. After a proper dissection, the width of the plantar fascia, the thickness of the medial border, and the width of the cut segment were measured and recorded. Any muscle damage on the flexor digitorum brevis and damaged area depth were recorded. Any damage on the lateral plantar nerve and the first branch of the lateral plantar nerve, also known as Baxter's nerve, and their distance to fasciotomy were also recorded. Mean width (± standard deviation) of the plantar fascia was measured as 20.34 ± 4.25 mm. The mean thickness of the medial border of the plantar fascia was 3.04 ± 0.54 mm. Partial fasciotomy was performed in all cadavers with 49.47% ± 7.25% relative width of the plantar fascia. No lateral plantar nerve, or its first branch Baxter's nerve, was damaged, and the mean distance from the deepest point of the fasciotomy up to the Baxter's nerve was 8.62 ± 2.62 mm. This cadaveric study demonstrated that partial plantar fasciotomy can be achieved via percutaneous plantar fascia release with a conventional hypodermic needle without any nerve damage.
