- The feasibility and reliability of an ultrasound examination to diagnose piriformis syndrome. [Journal Article]World Neurosurg 2019WN
- CONCLUSIONS: Ultrasound examination may assist in the clinical diagnosis of PS. It has the potential to be an alternative method in the diagnosis of PS for most musculoskeletal clinicians.
- Effect of piriformis injection on neuropathic pain. [Journal Article]Agri 2019; 31(4):178-182AGRI
- CONCLUSIONS: A piriformis injection was found to be effective for both somatic and neuropathic pain in piriformis syndrome patients. Long-term follow-up is needed in order to consider this option alongside other treatment alternatives, like botulinum toxin and myofascial release.
- Sciatic Nerve Variants in Patients Diagnosed With Sciatica: Is There a Correlation? [Journal Article]J Comput Assist Tomogr 2019 Nov/Dec; 43(6):953-957JC
- CONCLUSIONS: There is strong statistical significance regarding the relationship between sciatic nerve variation and the clinical diagnosis of sciatica. Preoperative magnetic resonance imaging can be considered in sciatica patients to prevent iatrogenic injury in pelvic surgery.
- Early morbidity and mortality after one-stage bilateral THA: Anterior versus posterior approach. [Journal Article]Orthop Traumatol Surg Res 2019; 105(7):1265-1270OT
- CONCLUSIONS: In selected patients (ASA score 1 or 2 and age ≤80 years), 1B-THA was not followed by any early deaths in the patients managed using the anterior or posterior approach. Total early morbidity rates were low. Neither the types of complications nor the early re-admission rates differed between the AA and PA groups. The shorter operative time in the AA group is ascribable to change in patient installation between the two arthroplasties when the PA is used.
- Myositis ossificans traumatica of the piriformis muscle: a rare mature case in an adult African male. [Journal Article]Surg Radiol Anat 2019; 41(12):1513-1517SR
- Myositis ossificans traumatica (MOT) is a common form of heterotopic ossification associated to trauma. Rare mature manifestations and topographically atypical presentations of MOT are often misdiagnosed as osteosarcoma. This case study discusses a rare, mature case of MOT of the piriformis muscle, potentially clinically associated with piriformis syndrome. The ossification was observed on a dry …
Myositis ossificans traumatica (MOT) is a common form of heterotopic ossification associated to trauma. Rare mature manifestations and topographically atypical presentations of MOT are often misdiagnosed as osteosarcoma. This case study discusses a rare, mature case of MOT of the piriformis muscle, potentially clinically associated with piriformis syndrome. The ossification was observed on a dry sacral bone of an adult skeleton belonging to a South African male during routine inventory of the Raymond A. Dart Collection of Human Skeletons, the University of the Witwatersrand, Johannesburg. The MOT was located on the anterior aspect of the sacrum at a site corresponding to the upper portion of the origin of the muscle and extended laterally towards the greater trochanter, beyond the greater sciatic notch. It was cylindrical in shape and measured approximately 52.70 mm in length and 12.10 mm in diameter. Micro-focus CT revealed an extensive and mature bony development of the piriformis muscle with distinct outer cortical and inner trabecular bone. In addition, the skeleton showed widespread healed skeletal trauma, suggesting a history of trauma. The MOT was completely fused to the sacral bone excluding the possibility of congenital anomalies. Information on the MOT of the piriformis muscle is vital to clinicians and radiographers to aid in successful diagnosis and management of the piriformis syndrome and sciatica in the gluteal region. This case also provides a rare example to biological anthropologists, paleoanthropologists and bioarchaeologists of the representation of pathologies like these on a dry bone sample.

- Sciatic nerve and its variations: is it possible to associate them with piriformis syndrome? [Journal Article]Arq Neuropsiquiatr 2019; 77(9):646-653AN
- CONCLUSIONS: The results of this review showed the most prevalent variations of the sciatic nerve and point to a possible association of this condition with piriformis syndrome. Therefore, these variations should be considered during the semiology of disorders involving parts of the lower limbs.
- Complementary Specific Pelvic Sequences on Routine Lumbar Magnetic Resonance Imaging Scans: An Imaging-Based Study Focused on Piriformis Syndrome. [Journal Article]Turk Neurosurg 2019; 29(5):698-704TN
- CONCLUSIONS: Although PS being a clinical diagnosis, this study indicated that in patients whom PS was not suspected at the initial examination, 8.2% of them were finally diagnosed after MRI evaluations. Performing specific pelvic sequences as an adjunct to routine lumbar MRI can salvage underdiagnosed patients with PS and facilitate early detection of this pathological condition.
- Ultrasound-guided dry needling decreases pain in patients with piriformis syndrome. [Journal Article]Muscle Nerve 2019; 60(5):558-565MN
- CONCLUSIONS: The findings suggest that DN resulted in clinically meaningful short-term improvement in pain intensity of patients with PMS.
