“…Despite treatment with physiotherapy, analgesics, and an L5-S1 arthrodesis, the patient's pain became progressively worse, preventing her from work. 37 Five subsequent MRI examinations revealed no abnormal findings in the lumbosacral spine and left hip. 37 MRN over the left hip region eventually revealed an accessory muscle belly of the left piriformis with the fibular branch of the sciatic nerve passing between the fibers of this accessory belly and the standard piriformis muscle.…”

“… 37 MRN over the left hip region eventually revealed an accessory muscle belly of the left piriformis with the fibular branch of the sciatic nerve passing between the fibers of this accessory belly and the standard piriformis muscle. 37 In this case, MRN provided a definitive diagnosis regarding the etiology of the patient's pain, which subsequently allowed accurate presurgical planning for endoscopic release of the piriformis. 37 38 39 40 …”

Peripheral nerve injuries (PNIs) continue to present both diagnostic and treatment challenges. While nerve transections are typically a straightforward diagnosis, other types of PNIs, such as chronic or traumatic nerve compression, may be more difficult to evaluate due to their varied presentation and limitations of current diagnostic tools. As a result, diagnosis may be delayed, and these patients may go on to develop progressive symptoms, impeding normal activity. In the past, PNIs were diagnosed by history and clinical examination alone or techniques that raised concerns regarding accuracy, invasiveness, or operator dependency. Magnetic resonance neurography (MRN) has been increasingly utilized in clinical settings due to its ability to visualize complex nerve structures along their entire pathway and distinguish nerves from surrounding vasculature and tissue in a noninvasive manner. In this review, we discuss the clinical applications of MRN in the diagnosis, as well as pre- and postsurgical assessments of patients with peripheral neuropathies.

“…Anatomical variations of nerve pathway can also cause chronic pain. Polesselo et al reported a case of deep gluteal pain in a 42-year-old women, with 17 years of evolution, due to an anatomical variation of the sciatic nerve in relation to the piriform muscle, confirmed with neurography with aid of magnetic resonance 20 .…”

the making of the posterior arthroscopic portal to the hip joint must be done with careful marking of the trochanter massive; should there be difficult to find it, a small surgical access is recommended. The access point to the portal should not exceed two centimeters towards the posterior superior aspect of the greater trochanter, and must be made with the limb in internal rotation of 15 degrees.

Gluteal pain is a frequent symptom in athletes, and defining it etiologically is a challenge for orthopedists. In the present study, using an anatomical approach to the posterior region of the pelvis and the proximal femur, divided into four quadrants, systematized investigation is proposed with the aim of optimizing the treatment and accelerating athletes’ return to their sport, through correct diagnosis.
