On the anterior aspect of the thigh, identify the major cutaneous nerves [Figure 11.2A (anterior), Figure 11.2B (posterior)]. These nerves pierce the fascia lata to enter the superficial fascia.
Note: As the cutaneous nerves are identified, study the distribution of the dermatomes of the lower extremity (Figure 11.3). Clinically, nerve lesions involving the lower extremity may result from injuries to peripheral nerves or injuries to spinal nerves. The latter is often due to compression of the spinal nerves in the lumbar region of the spine. Therefore, it is important to have a basic understanding of both the distribution of peripheral nerves and the dermatomes.
