Anatomy of Toenail
The average growth rate of toenails is about 1 mm a month. The rounded shape of the free edge of the nails is dictated by the shape of the lunula. After avulsion of a nail, the free edge of the new one grows parallel to the lunula.

Anterior Compartment of the Thigh Anatomy

Anterior Compartment of the Thigh Anatomy


Anterior Compartment of the Thigh Anatomy
The anterior compartment is the largest in the thigh, occupying the region between the inguinal ligament and the knee. Lateral and anteromedial intermuscular septa separate the contents from the posterior (hamstring) and medial (adductor) compartments, respectively (Fig. 6.2). The anterior compartment (Fig. 6.12) contains quadriceps femoris, sartorius and the tendon of iliopsoas, and is innervated by the femoral nerve. The femoral artery and vein, the principal vessels of the lower limb, traverse the compartment and leave via the opening in adductor magnus to gain the popliteal fossa.

Subcutaneous tissue (superficial fascia)
The subcutaneous tissue contains the great (long) saphenous vein and its tributaries with their accompanying arteries, superficial inguinal lymph nodes and cutaneous nerves. The great saphenous vein ascends on the medial side of the thigh (Fig. 6.11) and passes through the saphenous opening in the fascia lata to empty into the femoral vein. The great saphenous vein drains the superficial tissues of the entire limb except the lateral side of the leg and foot. Near its termination, the vein receives tributaries, which drain the buttock, the perineum and the abdominal wall below the umbilicus. These tributaries are accompanied by corresponding branches of the femoral artery. The superficial inguinal lymph nodes, often palpable in the living, lie just distal and parallel to the inguinal ligament and adjacent to the termination of the great saphenous vein (Fig. 6.11). These nodes receive lymph from the same superficial tissues as those drained by the great saphenous vein and its tributaries. Efferent lymphatics from the superficial nodes pass through the fascia lata and drain into the deep inguinal nodes within the femoral triangle and femoral canal, where nodes are a focal point in lymphatic drainage of the lower limb (p. 257).
Medial Compartment of the Thigh Anatomy

Medial Compartment of the Thigh Anatomy


Medial Compartment of the Thigh Anatomy
The medial compartment of the thigh is wedge­shaped and lies between the anterior and posterior compartments. It contains pectineus, adductors longus, brevis and magnus, gracilis and obturator externus. The obturator nerve and vessels and the profunda femoris vessels, together with their perforating branches, supply the compartment.

Muscles
The muscles are arranged in three layers. The anterior layer consists of pectineus, adductor longus and gracilis, from lateral to medial (Fig. 6.21). Deep to these, forming the intermediate layer, is adductor brevis (Figs 6.22 & 6.23). The posterior layer consists of obturator externus and adductor magnus (Figs 6.24 & 6.25). The proximal attachments of these muscles are to the outer surface of the bony pelvis between the superior pubic and ischial rami. In addition, obturator externus is attached to the obturator membrane.

Gluteal Compartment Anatomy

Gluteal Compartment Anatomy


Gluteal Compartment Anatomy
The gluteal region or buttock forms part of the root of the limb. It overlies the dorsum of the ilium, ischium and sacrum and is continuous proximally with the lower trunk and distally with the posterior compartment of the thigh. Three substantial muscles (gluteus maximus, medius and minimus), covered by deep fascia and a thick layer of subcutaneous fat, form the bulk of the buttock and account for its surface contour. The gluteal fold, a prominent surface feature, lies at the junction of the buttock and thigh.


Gluteus maximus
This very large trapezoidal muscle is the most superficial in the buttock. Its fibres slope downwards and laterally (Fig. 6.28) and its lower edge passes obliquely across the gluteal fold. Some of the sensory nerves to the skin of the buttock penetrate the medial part of the muscle, while others emerge around its upper and lower borders. Proximally, the muscle has an extensive attachment: to the ilium behind the posterior gluteal line, to the lower part of the sacrum, to the coccyx, to the sacrotuberous ligament and to the thoracolumbar (lumbar) and gluteal fasciae. A synovial bursa is usually present where it crosses the ischial tuberosity. Distally, some of the deeper fibres are attached to the gluteal tuberosity of the femur (Fig. 6.29), but most of the muscle is attached through the iliotibial tract (Fig. 6.30) to the anterior surface of the lateral tibial condyle. The nerve supply is from the inferior gluteal nerve (L5, S1 & S2).
