Ossifications in the caudal attachments of the ligamentum flavum were studied on 121 dried thoracic spines. Most of them were aged. Frequency increased in a caudal direction. At T12, frequency depended on the orientation of the zygapophyseal joints of T11-12 which determined the range of rotation. When they were of thoracic orientation, allowing large range(More)
The deformations and stresses acting on the acetabular rim have not been very precisely documented. The authors present a study based on an experimental simulation of hip loading with anatomic correlations. 122 dissections were performed in order to define the anatomic aspect of the roof (and especially of Byers's "area 17") and the intermediate area(More)
The ligaments of the ankle are superficial and easily accessible at ultrasonography. Surprisingly, the reliability of this technique has never been proven. With this goal in mind, ten ankles were subjected to a ultrasono-anatomic comparison. The five principle ligamentous fascicles (three on the lateral side and two on the medial side) measured at(More)
The authors describe the distribution of the medial branches of the upper thoracic dorsal rami (T1 to T5 levels). At each level, after travelling through the erector spinae, they become superficial, and reach the apex of the spinous process of the corresponding vertebra. They then spread out laterally, innervating the skin. They can occasionally be(More)
The authors report a series of 41 dissections of the forearm intended to study the orientation of the fibers of the flexor carpi radialis (FCR). This shows that there is a constant torsion of the fibers of the FCR by an average of 180 degrees. Half of this torsion occurs in the forearm and half in the sheath of the FCR at wrist level. Awareness of this(More)
The putting in tension of the dorsal aponeurosis of the digits induces its retraction and the nearness of its insertions on the basis of the 3 phalanges. It depends on the extensor digitorum, interosseous and lumbrical muscles. The aponeurosis is not a single driving belt, but set off in itself 3 types of reaction: 1) The gliding on the sides of the(More)
The volar fascicles of the interosseous muscles possess two separate components: the proximal and glenoidal one, the distal and aponeurotic other. The armature of the dorsal aponeurosis is constituted the deep, the central and the collateral expansions of the extensor digitorum muscles, and the interosseous muscles, whom are added the lumbrical muscles. The(More)
The study of the extensor apparatus through different methods concerns 200 fingers, the most of fresh cadavers. The dissection through direct observation or with surgical microscope of the dorsal aponeurosis of 30 fingers has been completed by an histological study of 10 fingers. The mechanic properties of each dorsal aponeurotic structure has been tested(More)
