As the flexion, adduction, internal rotation (FAIR) test was positive and there was tenderness with deep palpation of the gluteal region, the etiology was suspected as piriformis syndrome
A large muscle in the buttock area, the piriformis connects the femur (thighbone) to the spine.
can be the result of buttock and hip pain caused by TPs in the piriformis muscle alone or by compression of the sciatic nerve by the shortened and thickened piriformis muscle.
is an extraspinal entrapment neuropathy in which the piriformis muscle compresses the sciatic nerve, causing sciatica .
Bilateral piriformis syndrome
was suspected after exclusion of the other pathologies using electrodiagnostic studies and lumbar magnetic resonance imaging.
Some of them include herpes zoster, infection, lumbar nerve root tumor, spinal instability, excessive hypertrophy of the facet joint, ankylosing spondylitis, sacroiliitis, sciatic neuritis, piriformis syndrome
, intrapelvic mass (hypertrophic ossification), intraspinal ganglion cyst, endometriosis, adenomyosis, coxarthrosis, et cetera.
Thus, peripheral nerve entrapment syndromes, such as piriformis syndrome
and carpal tunnel syndrome, may be treatable by direct PRF.
1 Piriformis syndrome
was first described by Yeoman in 1928.
They discuss the pretherapeutic history of botulinum neurotoxin, the history of its clinical development, its pharmacology and immunological properties, and treatments for cervical dystonia, blepharospasm, oromandibular dystonia, laryngeal muscle hyperactivity syndromes, otorhinolaryngological conditions, hemifacial spasm, spasticity, spastic infantile cerebral palsy, tic disorders, essential hand and head tremor, stiff-person syndrome, ophthalmological applications, cosmetic uses, hyperhidrosis, ischemic digits, neuropathic pain, headaches, musculoskeletal pain and arthritis, plantar fasciitis, low-back pain, piriformis syndrome
, the gastrointestinal tract, and urological disorders.
The main causes of low back pain are: disc protrusions and herniations; spinal canal stenosis of lumbar spondylolisthesis; and piriformis syndrome
Some practitioners diagnose piriformis syndrome
as a sciatica source when back pain is absent.
But a new study suggests the cause of sciatica pain may actually be piriformis syndrome
, a condition in which a muscle in the buttocks called the piriformis compresses or irritates the sciatic nerve.
