Innervation of the Posterior Hip Capsule: A Cadaveric Study

Abstract Objective Recent studies of hip anatomy have turned to the posterior capsule better understand anatomic location capsular sensory branches and identify nerves with potential for neural blockade. Current literature has shown is primarily supplied by from sciatic nerve, nerve quadratus femoris, superior gluteal (1, 2). This cadaveric study investigated gross hip, while also identifying targets analgesia, emphasis on femoris. Design Cadaveric study. Setting UT Health San Antonio Anatomy Lab. Methods In total, 10 total cadavers (18 hips total), were posteriorly dissected nerve. Nerves labeled radio-opaque markers. Following dissections, fluoroscopic images obtained at sequential angles help expand knowledge interventional pain procedures. Results The was in 1/16 hips, femoris 15/18 6/18 hips. Conclusions reliably innervates joint. Both small articular that may be involved innervation, but this not seen commonly. results elucidate novel therapeutic treatment chronic refractory (i.e., femoris).
