the detail that forms the floor of the Scarpa triangle is important
The portion of the psoas major arises from the T12 vertebrae and the first five lumbar vertebrae T12-L5, as well as at the base of the corresponding transverse processes, and descends into the iliac fossa of the coxal, where it joins the iliac portion. The vertebral insertion is somewhat curious, since they are different arches that are superimposed from one intervertebral disc to the other.
the detail that forms the floor of the Scarpa triangle is important
The iliopsoas muscle is a compound muscle that is made up of the psoas major and the iliacus muscle.. Before speaking of psoas iliac: stretching, you need to know it in depth.
The iliac head is created superiorly on the inner lip of the iliac crest., anterior iliac spines, Superior and inferior, base of the sacred, part of the internal iliac fossa, Iliolumbar ligament and lateral aspect of the anterior aspect of the sacrum.
Both muscular bodies unite to pass under the inguinal ligament in the external area, having to insert it together in the lesser trochanter of the femur. In its course the iliopsoas is related to different organs, how are the kidneys, diaphragm, ureters, renal vessels, blind, colon, common iliac arteries and external iliac arteries and veins. It has a very intimate relationship with the lumbar plexus, which is responsible for passing through the muscle.
This iliopsoas is innervated by direct branches of the lumbar plexus and the femoral nerve.. The lower portion below the inguinal ligament forms part of the floor of the so-called femoral triangle..
Action
The iliopsoas generally moves the lower limb free, causing hip flexion to lift the limb and start walking when the opposite limb assumes body weight. Nevertheless, can also be in charge of moving the trunk; bilateral iliopsoas contraction initiates trunk flexion at the hip of the fixed thigh. This is also a postural muscle, that is active and maintains normal lumbar lordosis and resists hyperextension of the coxal joint.
insertion, origen, innervation and irrigation
About the iliopsoas you have to know the following aspects, starting with the insertion that the upper one has in the bodies of the last dorsal vertebra (D12) and the first five lumbar, while the lower one takes place in the lesser trochanter of the femur.
As regards the origin, the psoas part occurs on the lateral aspects of the lumbar vertebrae, on the anterior aspects of the transverse processes and intervertebral discs from the 12th thoracic vertebra to the 5th lumbar vertebra, while the iliac part has its origin in the inner face of the iliac fossa.
Regarding the innervation , The two muscles that make up the iliopsoas are innervated by different branches.. In the case of the psoas major, it is due to the branches of the anterior branch of the lumbar plexus., de L1 a L3. For his part, the iliac does it by the branches of the femoral nerve (L2, L3).
Finally, the irrigation is also divided according to the portions of the iliopsoas muscle. Nevertheless, some muscles share the same blood supply. The psoas major is supplied by the lumbar arteries., that is to say, branches of the abdominal aorta artery, and the external iliac, the continuation of the abdominal aorta artery. For his part, the iliacus is only irrigated by part of the external iliac artery.
How to stretch the iliopsoas
If you are looking for psoas iliac: stretching, We are going to explain a simple way to do it so that you can prevent injuries and treat other problems.. To be able to carry out the stretching in an appropriate way, must be placed with one leg stretched behind and another that is bent in front.
In this position, you should try to bring your pelvis as close to the ground as possible.. Then you must maintain the position and repeat the movement with the other leg.. In this way, with this maneuver the psoas muscle that is stretched is that of the leg that is extended.
Common mistakes in iliopsoas stretching
There are some common mistakes that occur when doing the iliopsoas stretch., as they are:
- Do not do pelvic retroversion. It is key to do it without arching the lower back, that is to say, contracting the abs and buttocks but not doing so.
- Have a misaligned back is one of the most common mistakes. The posture must be correct for a greater effectiveness of the exercise.
- Destabilization. You have to try to reach higher stretch ranges as long as you are stable; and if you see that you have to keep your balance, you will perform the first step of the exercise and then do it by raising your arm.
- stretch too much It is one of the most common mistakes.. It is necessary to look for an intensity that allows us to maintain it with a good posture without destabilizing ourselves.. You must go as far as you get tension, but don't force too much.
