Minimally invasive techniques have also gained popularity in other facets of foot and ankle surgery, including bunionette correction. The main objective of this study was to evaluate computed tomography (CT)-derived Hounsfield units (HUs) from four quadrants of the fifth metatarsal head evaluating regional bone density.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Methods:<\/jats:bold>\n                    A retrospective analysis was conducted of 30 patients without a history of osteoporosis, fracture, or previous surgery who underwent CT examination. The fifth metatarsal head was separated into quadrants in the coronal plane and CT-derived HUs from a 3.5-mm region of interest centered in each quadrant were obtained. Quadrant HU values were compared using an analysis of variance followed by post hoc testing. The threshold for statistical significance was set at\n                    <jats:italic>P<\/jats:italic>\n                    \u2264 .05.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results:<\/jats:bold>\n                    The average cohort age was 43 \u00b1 15 years. The sample was composed of 20 females (67%) and ten males (33%). There existed a statistically significant difference among the fifth metatarsal head quadrants (\n                    <jats:italic>P<\/jats:italic>\n                    &lt; .001).
