“…Solomon et al (2010), in their study of 20 hip dissections, found OI attaching to the surrounding rami of the obturator foramen in all specimens. In addition to this, Wu et al (2012), using both ultrasonography and cadaveric dissections, identified additional attachments on the lateral pelvic wall in 15 cadavers. One textbook source further refers to the margin of the lesser sciatic notch but this may have been imprecisely redacted from a detailed anatomical study of 14 cadavers (Shinohara, 1995) which found that OI converged on "a saddle-shaped cartilage" overlying the lesser sciatic notch.…”

An appraisal of the short lateral rotators of the hip joint

The short lateral rotators (piriformis, obturator internus, superior and inferior gemelli, obturator internus, and quadratus femoris) are functionally important muscles, significantly contributing to hip joint stability. They act as "postural muscles", holding the femoral head in the acetabulum during hip movements, thus are frequently monitored in gait analysis and for muscle rehabilitation post-injury. Despite the need to precisely identify and repair these muscles for stability postoperatively, clinical complications have resulted from the inadequate and inconsistent understanding of their morphological and functional anatomy. Furthermore, the short lateral rotators have complex entheses (osteotendinous insertions on bone) and may be subject to overuse injury in sport. This study aims to review the reported morphology of the short lateral rotators in order to ascertain whether discrepancies exist in our understanding of these muscles, and if further investigation is required to aid in gait analysis, clinical management of hip pathologies, and prevention of overuse injuries. Following a literature search strategy, 59 primary references were retrieved from three databases, with additional 26 anatomical textbooks selected for critical evaluation. Numerous inaccuracies and inconsistencies in the anatomical descriptions of the attachments, patterns of innervation and actions exist, and often insufficiently supported by primary findings. There is also a paucity of information regarding the architectural pattern of the muscles, which would be useful in clarifying the function of these dynamic stabilizers of the hip joint. A better anatomical understanding of these muscles will better inform hip reconstruction and lead to improved surgical outcomes by reducing post-operative complications.

“…Several Authors considered the MRI essential to the location, classification, and evaluation of the injury size 11,14 . However, is important to underline that also the US examination shows a high sensitivity and specificity in IO assessment 15 . Concerning MRI assessment some Authors suggest the use of standard high-field -1.5 or 3T 11 .…”

Introduction: Traumatic groin pain syndrome can result from any acute trauma, but usually it is due to an indirect muscle injury (overstretching of the muscle fibers). The internal obturator muscle externally rotates the thigh and contributes to the stabilization of the hip joint. The indirect injury of this muscle may cause the onset of traumatic groin pain syndrome. Purpose: To perform a systematic review of the literature concerning the indirect injury of internal obturator muscle in relationship to the onset of groin pain syndrome. Conclusion: IO lesions are rare but important causes of traumatic groin pain syndrome, and despite their low incidence they must be considered during evaluation of patients with this pathology. Study design: Systematic review. Level of evidence: IV.
