Muscular Lacuna

	Muscular Lacuna The muscular lacuna (Latin: ''lacuna musculorum'') is the lateral compartment of the thigh inferior to the inguinal ligament, for the passage of the iliopsoas muscle, the femoral nerve and the lateral cutaneous nerve of the thigh; it is separated by the iliopectineal arch from the vascular lacuna The vascular lacuna (Latin: ''lacuna vasorum'') is the compartment beneath the inguinal ligament which allows for passage of the femoral vessels, lymph vessels and lymph nodes.

	Inguinal Ligament The inguinal ligament (), also known as Poupart's ligament or groin ligament, is a band running from the pubic tubercle to the anterior superior iliac spine. It forms the base of the inguinal canal through which an indirect inguinal hernia may develop. Structure The inguinal ligament runs from the anterior superior iliac crest of the ilium to the pubic tubercle of the pubic bone. It is formed by the external abdominal oblique aponeurosis and is continuous with the fascia lata of the thigh. There is some dispute over the attachments. Structures that pass deep to the inguinal ligament include: Psoas major, iliacus, pectineus Femoral nerve, artery, and vein Lateral cutaneous nerve of thigh Lymphatics Function The ligament serves to contain soft tissues as they course anteriorly from the trunk to the lower extremity. This structure demarcates the superior border of the femoral triangle. It demarcates the inferior border of the inguinal triangle. The midpoint of the ingui ...

	Iliopsoas Muscle The iliopsoas muscle (; from lat, ile, lit=groin and grc, ψόᾱ, psóā, muscles of the loins) refers to the joined psoas major and the iliacus muscles. The two muscles are separate in the abdomen, but usually merge in the thigh. They are usually given the common name ''iliopsoas''. The iliopsoas muscle joins to the femur at the lesser trochanter. It acts as the strongest flexor of the hip. The iliopsoas muscle is supplied by the lumbar spinal nerves L1– L3 (psoas) and parts of the femoral nerve (iliacus). Structure The iliopsoas muscle is a composite muscle formed from the psoas major muscle, and the iliacus muscle. The psoas major originates along the outer surfaces of the vertebral bodies of T12 and L1– L3 and their associated intervertebral discs. The iliacus originates in the iliac fossa of the pelvis. The psoas major unites with the iliacus at the level of the inguinal ligament. It crosses the hip joint to insert on the lesser trochanter of the femur. T ...

	Femoral Nerve The femoral nerve is a nerve in the thigh that supplies skin on the upper thigh and inner leg, and the muscles that extend the knee. Structure The femoral nerve is the major nerve supplying the anterior compartment of the thigh. It is the largest branch of the lumbar plexus, and arises from the dorsal divisions of the ventral rami of the second, third, and fourth lumbar nerves (L2, L3, and L4). The nerve enters Scarpa's triangle by passing beneath the inguinal ligament, just lateral to the femoral artery. In the thigh, the nerve lies in a groove between iliacus muscle and psoas major muscle, outside the femoral sheath, and lateral to the femoral artery. After a short course of about 4 cm in the thigh, the nerve is divided into anterior and posterior divisions, separated by lateral femoral circumflex artery. The branches are shown below: Muscular branches * The nerve to the pectineus muscle arises immediately above the inguinal ligament from the medial side of the femoral n ...

	Lateral Cutaneous Nerve Of The Thigh The lateral cutaneous nerve of the thigh (also called the lateral femoral cutaneous nerve) is a cutaneous nerve of the thigh. It originates from the dorsal divisions of the second and third lumbar nerves from the lumbar plexus. It passes under the inguinal ligament to reach the thigh. It supplies sensation to the skin on the lateral part of the thigh by an anterior branch and a posterior branch. The lateral cutaneous nerve of the thigh can be investigated using ultrasound. Local anaesthetic can be injected around the nerve for skin grafts and surgery around the outer thigh. Nerve compression (usually around the inguinal ligament) can cause meralgia paraesthetica. Structure The lateral cutaneous nerve of the thigh is a nerve of the lumbar plexus. It arises from the dorsal divisions of the second and third lumbar nerves (L2-L3). It passes through psoas major muscle, and emerges from its lateral border. It crosses the iliacus muscle obliquely, toward the anterior superior iliac ...

	Iliopectineal Arch The Iliopectineal arch is a thickened band of fused iliac fascia and psoas fascia passing from the posterior aspect of the inguinal ligament anteriorly across the front of the femoral nerve to attach to the iliopubic eminence of the hip bone posteriorly. The iliopectineal arch thus forms a septum which subdivides the space deep to the inguinal ligament into a lateral muscular lacuna and a medial vascular lacuna. When a psoas minor muscle is present, its tendon of insertion blends with the iliopectineal arch It is sometimes transected in treatment of femoral nerve The femoral nerve is a nerve in the thigh that supplies skin on the upper thigh and inner leg, and the muscles that extend the knee.

	Vascular Lacuna The vascular lacuna (Latin: ''lacuna vasorum'') is the compartment beneath the inguinal ligament which allows for passage of the femoral vessels, lymph vessels and lymph nodes. Its boundaries are the iliopectineal arch, the inguinal ligament, the lacunar ligament, and the superior border of the pubis. The structures found in the vascular lacuna, from medial to lateral, are: * Cloquet's node; * Femoral vein; * Femoral artery; and * Femoral branch of the genitofemoral nerve The vascular lacuna is separated from the muscular lacuna The muscular lacuna (Latin: ''lacuna musculorum'') is the lateral compartment of the thigh inferior to the inguinal ligament, for the passage of the iliopsoas muscle, the femoral nerve and the lateral cutaneous nerve of the thigh; it is separate ... by the iliopectineal arch. The lacunar ligament can be a site of entrapment for femoral hernias.Ross, L.M., Lamperti, E.D. (2006). Thieme: Atlas of Anatomy: 489 References Muscular system ...
