The FRONT block (Femoral Rami Obturator Nerve Trunk) is a newly developed dual-injection technique providing comprehensive anesthetic coverage of the anterior hip joint by targeting both the sensory femoral rami and the ON trunk.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>15 intact cadaveric sides from eight embalmed cadavers were dissected after FRONT block administration with one injection and two dye deposits in the iliopsoas plane and in the subpectineal compartment under dynamic ultrasonography. The primary outcome was dye spread to the sensory hip articular branches of the femoral nerve (FN) and the ON trunk evaluated during the gross anatomical dissection. Secondary outcomes included identifying landmarks for accurate injection of dye and measuring the distance from the needle trajectory to the femoral and the lateral femoral cutaneous nerves (LFCN).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In 86.7% of cadaver sides, the FRONT block successfully covered both the sensory femoral rami and the ON trunk. The injection was performed 6.7\u2009cm (SD 1.6) distal to the anterior superior iliac spine with a medial deviation of 1.8\u2009cm (SD 2.1). The average distance from the needle trajectory to the FN was 0.8\u2009cm (SD 0.4) and 3.7 (SD 2.1) cm to the LFCN.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The FRONT block offers reliable coverage of the anterior hip joint and capsule.
