The lateral femoral cutaneous nerve arises from the femoral nerve
Has a cutaneous branch only and supplies the upper and lateral part of the thigh
It emerges from the lateral border of psoas major and moves towards the anterior superioriliac spine, under the inguinal ligament and into the thighVariations in normal anatomy and nerve route existSlide3
Entrapment or dysfunction of the lateral femoral cutaneous nerve causing localized paraesthesia and numbness on the anterolateral aspect of the thighSlide4
Mechanism of Injury
PregnancyWearing belts, corsets or tight trousersLeg length discrepancyLead poisoningAlcoholismDiabetes mellitus
Iatrogenic (caused by medical examination or treatment)
Obtaining Iliac crest bone grafts
Laparoscopic inguinal herniaSlide5
Paraesthesia in the upper and lateral thigh
Burning, stinging sensation of the skinAggravated by pressure over inguinal ligamentAggravated by positions of hip extensionEased by sitting downSlide6
over the lateral inguinal ligament
Hair loss over anterior thigh due to patient rubbing the areaReduced sensation upper and lateral thighMay have allodynia over the upper and lateral thighSlide7
Nerve conduction studySlide8
Conservative management usually attempted with a good chance of success in 4 – 6 months
Usually involves treating the underlying cause such as weight loss, wearing tight clothes, belts
etcPhysiotherapy not usually considered but can be used in some casesSlide9
Local anaesthetic blockSlide10
of constricting tissue
Neurolysis and transposition of the lateral femoral cutaneous nerveSlide11
