The present research aims to study the anatomical relationship between the deep peroneal nerve and the neighboring structures in the proximal fibula of Thais, with special regard to define the boundaries of a "safe" area when performing a biopsy of the proximal fibula. The proximal parts of 118 legs of 59 formalin-embalmed adult cadavers (31 males, 28 females) were investigated. The distance from the apex of the fibular head to the point of origin of the deep peroneal nerve, the distance from the most lateral prominence of the fibular head to the anterior intermuscular septum, and the angle between the deep peroneal nerve and the fibula axis were measured. The results showed that the mean distances from the apex of the fibular head to the point of origin of the deep peroneal nerve was 28.4 +/- 4.8 mm and from the most lateral prominence of the fibular head to the anterior intermuscular septum was 14.9 +/- 2.0 mm. The mean angle between the deep peroneal nerve and the fibular axis was 28.1 degrees +/- 7.2 degrees . In conclusion, these findings suggest that a "safe" area for bone biopsy in the proximal fibula of Thais is palpable anterior to the fibular head and downward laterally, not lower than 28 mm or 8% of the fibular length and from the most lateral prominence transverse medially not further than 14 mm. The inferior boundary of this area is an oblique line of the deep peroneal nerve about 28 degrees from the fibular axis.
