Sciatic Nerve Variants in Patients Diagnosed With Sciatica: Is There a Correlation?

Purpose Compression of the sciatic nerve in its path along the piriformis muscle can produce sciatica-like symptoms. There are 6 predominant types of sciatic nerve variations with type 1 being the most common (84.2%), followed by type 2 (13.9%). However, there is scarce literature on the prevalence of sciatic nerve variation in those diagnosed with sciatica. Materials and Methods The charts of 95 patients clinically diagnosed with sciatica who had a magnetic resonance imaging of the pelvis/hip were retrospectively studied. All patients had T1-weighted axial, coronal, and sagittal images. Magnetic resonance imagings were interpreted separately by 2 board-certified fellowship-trained musculoskeletal radiologists to identify the sciatic nerve variant. Results Seven cases were excluded because of inadequate imaging. Of the remaining 88 patients, 5 had bilateral sciatica resulting in a sample size of 93 limbs. Fifty-two (55.9%) had type 1 sciatic nerve anatomy, 39 (41.9%) had type 2, and 2 (2.2%) had type 3. The proportions of type 1 and 2 variations were significantly different from the normal distribution (P

ConclusionsAcupuncture in chronic sciatica patients is associated with normalized DMN activity and modulation of descending pain processing. The changes in the subclinical endophenotype of brain FC after acupuncture treatment may provide clues for understanding the mechanism of acupuncture ‐mediated analgesia in chronic pain.

ConclusionsCutibacterium acnes found in discs and vertebrae during surgery for disc herniation in adults with degenerated discs may be caused by contamination, as findings in this group were similar to findings in a control group of young patients with scoliosis and non-degenerated discs. Furthermore, such findings were almost always combined with bacterial findings on the skin and/or in the wound. There was no association between preoperative Modic changes and bacterial findings. Antibiotic treatment of lumbar disc herniation with sciatica and/or low back pain, without signs of clinical discitis/spondylitis, should be ser...

Abstract OBJECTIVE: The aim of the study was to investigate the occurrence of unexpectedly swollen nerve roots and to investigate the relationship between nerve root edema and recurrent radicular pain. METHODS: During the period from August 2010 to August 2015, a total of 462 patients with degenerative lumbar disease underwent surgery in this study group. Magnetic resonance imaging (MRI) was used to evaluate the details of the nerve root. Of the patients with recurring radiating pain 13 met the inclusion criteria of the study group and 24 patients without any complications volunteered as the control group. Th...

This study used Oswestry Disability Index (ODI)-self-comparison and showed that acupuncture treatments for lumber disc herniation and sciatica demonstrated significant improvement in long term clinical outcomes. A total of 112 lumbar disc herniation and sciatica cases were treated with electric acupuncture for pain relief and function improvement from July 1998 to December 2006.ResultsAll the 112 cases filled out the ODI forms prior to receiving treatment. Among the 112 patients, 23 of them did not finish the 6-week treatments. 89 cases were evaluated with ODI after 6-week acupuncture treatments. Of those 89 cases, 67 case...

We presented a 23-year-old patient with a history of a sciatic pain of the right leg. A careful physical examination discovered tumor-like mass in the posterior part of the thigh. Neurological finding showed a reduction of myotatic reflexes on the right leg with a weaker muscle strength on the right leg. The right leg musculature was slightly hypotrophic in the range of 2-3 cm comparing to left leg. Initially electrophysiological and radiological diagnostic with magnetic resonance imaging (MRI) of the lumbar spine, pelvis and thighs were normal. Magnetic resonance imaging of the right thigh discovered a slow growing 2.1 &t...

CONCLUSIONS: Differential diagnosis of sciatica of extraspinal origin must rule out sacroiliac and hip joint so as deep gluteal space structures. Among these, quadratus femoris muscle is often overlooked as a pain-generator. Ultrasonography-guided intramuscular injections and a program of stretching and strengthening exercises can achieve durable control on the symptoms. PMID: 31282403 [PubMed - as supplied by publisher]

This study is a randomized, patient-assessor blind, two-arm, parallel, non-penetrating, sham-controlled clinical trial. Eligible participants will include adults (aged 19 –70 years old) with a clinical diagnosis of chronic sciatica (40 mm or more of a 100-mm visual analog scale (VAS) for bothersomeness) blinded to the treatment received. Patients will be randomly allocated into the acupuncture treatment group (manual acupuncture plus electroacupuncture (EA),n = 34) or the sham acupuncture control group (sham acupuncture plus placebo EA without electrical stimulation,n = 34).

Conclusions: Most primary psoas abscesses present with a delay in diagnosis because of the rarity of this infectious disease, the lack of specific symptoms and signs, and its similarity to many differential diagnoses. When suspected, CT-scan and/or magnetic resonance imaging help in making an accurate diagnosis and facilitate percutaneous or open surgical drainage of the abscess. Correct and fast identification of the microorganisms in addition to appropriate usage of antibiotic regimen improves the outcome. PMID: 30595960 [PubMed]

ConclusionsThe diagnostic accuracy of CT, myelography and MRI of today is unknown, as we found no studies evaluating today ’s more advanced imaging techniques. Concerning the older techniques we found moderate diagnostic accuracy for all CT, myelography and MRI, indicating a large proportion of false positives and negatives.

The authors report the case of a 76 year-old woman presenting with leg pain, numbness and weakness mimicking a lumbosacral radiculopathy. Lumbar spine magnetic resonance imaging (MRI) demonstrated mild root compression but lumbar decompression afforded only transient symptomatic relief. Post-operative MRI of the lumbosacral plexus and sciatic nerve revealed a gluteal venous varix compressing the sciatic nerve just distal to the piriformis muscle. Neurolysis and surgical resection of the offending varix resulted in resolution of her symptoms.
