    What are the curvatures of the spine?

    What are the curvatures of the spine?



    Seen from the front, the spine appears straight, while in profile it has four curvatures that give it greater resistance: the cervical curve convex anteriorly (cervical lordosis), the dorsal curve convex posteriorly (dorsal kyphosis), the lumbar curve again convex forward ( lumbar lordosis) and ...



    What are the curvatures of the spine and what function do they perform?

    The anterior curves are in the cervical and lumbar regions and are called lordosis whose characteristic is mobility, while the posterior ones are in the dorsal and sacral regions and are called kyphosis whose characteristic is rigidity.

    What types of abnormal curvatures are there?

    Seen from the back, the vertebral column normally appears straight, but, if viewed from the side, it describes 4 curves: cervical lordosis, thoracic kyphosis, lumbar lordosis and sacral kyphosis.

    What is not a physiological curve of the spine?

    Functions. The vertebral column is not straight but has a series of physiological curves; those with anterior concavity are called kyphosis (thoracic and sacro-coccygeal), those with posterior concavity are called lordosis (cervical and lumbar).


    What are the areas of the spine?

    12 vertebrae in the dorsal area, corresponding to the central part of the back, called thoracic or dorsal vertebrae. 5 vertebrae in the lumbar area, equivalent to the lower back, called the lumbar vertebrae. 5 vertebrae in the sacral area, located near the pelvis, called the sacral vertebrae.

    How many physiological curvatures of the spine are there?

    The spine has three natural curves that give it an S shape; the alignment of the spine is allowed by strong muscles.



    How are spinal curves indicated?

    The vertebral column, seen from the side, has four curves called respectively: cervical lordosis, dorsal kyphosis, lumbar lordosis, sacral kyphosis. Lordosis is a physiological curvature that has a posterior concavity. Kyphosis is an anterior concavity curvature.

    When are curves considered pathological?

    It often accompanies scoliosis or hyperkyphosis and is considered pathological when the curvature exceeds 40-50 degrees Cobb.

    What are the most frequent problems of the spine?

    The most frequent degenerative pathologies are: herniated disc; canal stenosis (i.e. narrowing of the canal through which the medulla and nerve roots pass); vertebral fractures that may have an osteoporotic, traumatic or oncological origin; vertebral tumors, which are over 10 percent ...

    What are spinal deformations?

    The most common spinal deformities in childhood include scoliosis (curve of the spine to a lateral one), kyphosis (curvature of the spine in the reverse direction), spondylolysis (stress fractures in the lower back) and spondylolisthesis ( one vertebra fools another).

    How to sleep in case of kyphosis?

    Kyphosis how to sleep? Correct posture during the night while we sleep helps kyphosis to remain in its natural condition. To keep kyphosis and lordosis in the most normal position, it is recommended to sleep in a lateral position with the legs bent.

    What are the main functions of the spine?

    Vertebrae are the bones that make up the spine. Their function is twofold: to protect the spinal cord, and to support the body. Damage to the vertebrae or intervertebral discs, which separate the vertebrae from each other, can cause health problems (eg herniated discs).

    How to tell if you have a crooked spine?

    Symptoms
    1. Shoulders at different heights (one shoulder blade more prominent than the other)
    2. Head not directly central to the pelvis.
    3. Hip raised and prominent.
    4. Coasts at different heights.
    5. Uneven hips.
    6. Variations in the color and texture of the skin covering the spine.

    How is dorsal kyphosis treated?

    Treatment for kyphosis varies according to the severity. The kyphotic attitude is generally treated with postural exercises, without having to resort to corrective braces or corsets, with excellent results. Structured kyphosis, on the other hand, may require correction with braces and, in severe cases, with surgical intervention.

    What does the Delmas index indicate?

    The Delmas rechideo index indicates the type of column that a given individual presents. It is the resultant of the ratio between the height (H) multiplied by 100 and its length (L), that is H * 100 / L.

    What are the paramorphisms affecting the spinal column?

    Paramorphisms and dysmorphisms mainly affect the vertebral column or rachis and often, as a consequence, also the shoulders, the lower limbs and the foot. Examples of paramorphisms are: scoliosis, hyperkyphosis, hyperlordosis, flat back, winged shoulder blades, adducted shoulders, valgus knee, flat foot, hallux valgus.

    What are physiological curves and what is their function?

    The function of these curves is to maintain an upright position by increasing the ability to counteract the force of gravity, to adequately distribute the load between the vertebrae and to give the spine flexibility and mobility.

    What does dorsal kyphosis mean?

    The term kyphosis indicates the curvature of the upper part of the vertebral column in an antero-posterior direction and with an anterior concavity: that modification affecting the back, that is, commonly known as "hump".

    How are the physiological curves of the spine formed?

    The physiological curves of the spinal column

    When we are born the spine is straight. Subsequently, after the first year of age, on the sagittal plane (looking sideways) different concavities can be identified, which take the name of "lordosis" and "kyphosis".

    What do signs of spondylosis mean?

    A degenerative alteration that affects the disc and posterior joints and is defined as a generalized osteoarthritis of the spinal column.

    What are the various portions of the spine called?

    Like the v., Also the column is divided into cervical, thoracic or dorsal, lumbar, sacral and coccygeal (fig. 2). The sacral tract constitutes the sacrum.

    How is the spine divided?

    The shape of the spine

    The column does not have a straight shape, on the contrary, it is characterized by a series of "curves"; convex (lordosis) anteriorly in the cervical and lumbar areas while concave (kyphosis) in the dorsal part.

    How many mobile vertebrae are there in the spinal column?

    The vertebral column is made up of 33 vertebrae (sometimes 34) and is divided into 5 regions: ... It is the most mobile part of the spine and consists of 7 vertebrae (cervical vertebrae, from C1 to C7) divided into an upper region (C1 and C2) and in a lower region (C3 to C7).
