Exempel på piriformis

• At the lower border of the piriformis muscle, the nerve turns backward and divides into upward and downward diverging branches, which enter the gluteus maximus.

• In those with sciatica due to piriformis syndrome, botulism toxin injections may improve pain and or function.

• Other stretches like piriformis stretch, and hands to feet stretch, can relieve stress off the muscles around the coccyx, after sitting for a long time.

• The biomechanical relationship between the sacroiliac joint, the piriformis muscle (see piriformis syndrome), and the sciatic nerve had not yet been discovered.

• The piriformis laterally rotates the femur with hip extension and abducts the femur with hip flexion.

• However, compression may be present, but not causal, in the setting of sciatica due to piriformis syndrome.

• Common causes of sciatica include the following lower back and hip conditions: spinal disc herniation, degenerative disc disease, lumbar spinal stenosis, spondylolisthesis, and piriformis syndrome.

• In 15% of the population, the sciatic nerve runs through, or under the piriformis muscle rather than beneath it.

• Thus, disproportionately weak hip abductors/gluteus medius muscles, combined with very tight adductor muscles, can cause the piriformis muscle to shorten and severely contract.

• Several medical conditions that can cause difficulty sitting are back injuries, sciatica, and piriformis syndrome.

• The inferior gluteal nerve reliably emerged inferior to the piriformis muscle.

• This position externally rotates the hip, lessening the stretch on the piriformis and relieving the pain slightly.

• This means the abductors on the outside can not work properly and strain is put on the piriformis.

• Piriformis syndrome does not occur in children, and mostly seen in women of age between thirty and forty.

• An exercise regimen targeting the gluteus medius and hip abductor muscle groups can alleviate symptoms of piriformis syndrome within days.
