  CHAPTER 25: ABDOMINAL WALLS
The aponeurosis of the internal oblique muscle divides into anterior and posterior layers, which pass, respectively, in front of and behind the rectus muscle to reach the linea alba.
The anterior sheath is comprised of the aponeurosis of the external oblique and an anterior layer of the aponeurosis of internal oblique; the posterior sheath of the posterior layer of the internal oblique and the aponeurosis of the transversus abdominis muscle.
Each abdominal aponeurosis is said to be bilaminar, and the six layers of each side are oblique and cross the median plane in a common area of decussation, namely the linea alba.

 Chapter 11: THE HAND
The palmar aponeurosis is a strong, triangular membrane overlying the tendons in the palm (fig.
The aponeurosis continues distally as four slips (pretendinous bands), which overlie the flexor tendons of the medial four fingers.
The central compartment is bounded (1) on the anterior side by the deep aspect of the palmar aponeurosis, (2) on the posterior aspect by a fat pad on the interosseous fascia and by the fascia anterior to the adductor pollicis muscle, and (3) on the sides by the fascia covering the thenar and hypothenar muscles.

 Bicipital aponeurosis - Wikipedia, the free encyclopedia
The bicipital aponeurosis (also known as lacertus fibrosus) is a broad aponeurosis that stems from the distal (insertion) tendon of the biceps brachii.
While the tendon of the biceps inserts on the radius, the aponeurosis stretches from the medial side of the biceps tendon and passes obliquely downward and medially across the brachial artery.
The bicipital aponeurosis reinforces the ceiling of the cubital fossa, and helps to protect the brachial artery and the median nerve.

 The Abdominal Wall
At this insertion the aponeurosis is fused with the aponeurosis of the transversus abdominis muscle to form the conjoint tendon.
The vas deferens, testicular artery and veins, lymph vessels, autonomic nerves, cremasteric artery, artery of the vas and the genital branch of the femoral nerve are covered by three layers of fascia derived from the abdominal wall.
The fascial covering of the spermatic cord is formed by the external spermatic fascia derved from the aponeurosis of the external oblique, the cremasteric fascia derived from the internal oblique and the internal spermatic fascia derived from the transversalis fascia.

 INTRODUCTION
After detaching the abductor hallucis on the medial side of the plantar aponeurosis, progressive dissection of the plantar surface of the aponeurosis from the aponeurotic tissue to the postero-medial tubercle of the calcaneus was made.
In 115 cases freeing of the plantar aponeurosis was performed with removal of the heel spur, whereas in 11 cases, the heel spur was left intouched.
We prefer freeing the plantar aponeurosis with excision of the abnormal areas in order to remove the scar tissue witch may be at the origin of the pain.

 Gray, Henry. 1918. Anatomy of the Human Body. Page 376
Where the muscular fibers are in a direct line with those of the tendon or aponeurosis, the two are directly continuous.
But where the muscular fibers join the tendon or aponeurosis at an oblique angle, they end, according to Kölliker, in rounded extremities which are received into corresponding depressions on the surface of the latter, the connective tissue between the muscular fibers being continuous with that of the tendon.
The latter mode of attachment occurs in all the penniform and bipenniform muscles, and in those muscles the tendons of which commence in a membranous form, as the Gastrocnemius and Soleus.

In spite of very complete anatomical descriptions of the palmar aponeurosis, many subjects of discussion remain which are of great practical value for the understanding of the factors that play a role in the development of Dupuytren's disease.
Early in its development, the aponeurosis appears as a specialized structure which has a retinacular function to retain the metacarpals and the flexor tendons as well as to support the palmar skin against compressive and shearing forces.
It is anchored on the aponeurosis of the hypothenar muscles and on the fibrous complex that surrounds the metacarpophalangeal joint.

 The Effect of Heel Elevation on Strain Within the Plantar Aponeurosis: In Vitro Study
The aim of this study was to quantify strain in the plantar aponeurosis in cadaveric feet with the use of various heel elevation configurations.
An in vitro method that simulated "static" stance was used to determine the loading characteristics of the plantar aponeurosis (n = 12).
Heel elevation was evaluated with blocks placed beneath the heel and with a contoured platform that simulated the arch profile of a shoe at three different heel heights (2.0, 4.0, 6.0 cm) with a level plane serving as the control.

The distribution of strain along the soleus aponeurosis tendon was examined during voluntary contractions in vivo.
Displacement and strain in the apparent Achilles tendon and in the aponeurosis were calculated from cine phase-contrast magnetic resonance images acquired with a field of view of 32 cm.
We suggest that the nonuniformity in aponeurosis strain within an individual was due to the presence of active and passive motor units along the length of the muscle, causing variable force along the measurement site.

Acquired ptosis usually presents in a way that the aponeurosis is dehiscing, as the tissues undergoing senescent changes.
The main approaches used in ptosis repair are by levator aponeurosis plication or by aponeurosis reinsertion into the tarsal plate.
Use of these two tools - plication of the aponeurosis or aponeurosis reinsertion - should be done under "monitored" or awake conditions.

In this repair, the external oblique aponeurosis is opened over the inguinal canal and the spermatic cord is skeletonized.
Originally a triple layer repair was performed where the transversalis fascia was opened and included with the internal oblique muscle and transverse abdominis aponeurosis and fascia and sewn with interrupted nonabsorbable suture to the iliopubic tract and the shelving edge of the inguinal ligament.
The McVay (Cooper's Ligament) Repair requires that the medial portion of the iliopubic tract must be excised to expose the medial edge of the femoral sheath and iliopectineal ligament (Cooper's) ligament for the placement of sutures.

(that is, onset after birth) are related to a deterioration of the levator aponeurosis (tendon) rather than the muscle itself, which remains healthy.
The aponeurosis develops areas of thinning, localized tears, or sometimes complete detachment and is no longer able to transmit the lift of the levator muscle to the margin of the eyelid.
Correction entails an exploration of the interior eyelid to determine the precise location and nature of the defect followed by a reinforcement or tucking of the weakened areas.

Since chiselling down the calcaneal [heel] spur also removes the attachment of the plantar aponeurosis [fascia], patients must accept subsequent lowering of the arch of the foot."

The aponeurosis is composed of dense fibrous connective tissue containing fibroblasts (collagen-secreting spindle-shaped cells) and bundles of collagen fibres in ordered arrays.
It says some anatomists define only the central band as the plantar aponeurosis, but that the medial and lateral bands' of the fascia are also aponeurotic (thicker and denser) as they get closer to the heel bone.
