The trochanters also are related to the posterior aspect of your femur from the bigger intertrochanteric crest.
The sensory and motor innervation towards the lower limb is supplied from the lumbosacral plexus, which can be formed through the ventral rami in the lumbar and sacral spinal nerves with supplemental contributions with the subcostal nerve (T12) and coccygeal nerve (Co1).
The distal conclusion in the fibula forms the lateral malleolus, which varieties the very easily palpated bony bump on the lateral side in the ankle.

The iliohypogastric (T12-L1) and ilioinguinal nerves (L1) arise from the psoas significant near the muscle's origin, from in which they run laterally downward to move anteriorly higher than the iliac crest in between the transversus abdominis and abdominal inside oblique, after which you can run previously mentioned the inguinal ligament.
