“…Posterior hip pain can be relieved by the resection and remodeling of the lesser trochanter of the femur. Preoperative and postoperative imaging evaluations have revealed an enlarged IFS and QFS, which have become specific indicators for evaluating IFI (1,14). In the present study, it was observed that the IFS and QFS changed dynamically with the change in position.…”

Background: The present study aimed to use magnetic resonance (MR) to explore the dynamic changes of the ischiofemoral space (IFS) under the triaxial motion of the hip joint and verify the clinical test mechanism for ischiofemoral impingement (IFI).Methods: A prospective design was used to screen 37 patients with clinically confirmed IFI, which included a total of 67 lateral hips, and 39 healthy controls with a total of 69 lateral hips. A dynamic MR examination was performed in positions designed by a simulated IFI test (adduction, adduction with 30° external rotation, 30° internal rotation, supine with 30° flexion, and prone with 30° backward extension). The IFS (mm) and quadratus femoris space (QFS, mm) were measured in different positions. All the data were evaluated independently by three musculoskeletal radiologists. The differences between the two groups were compared using the two-tailed t-test. Results:The IFS and QFS in the case group were smaller than those in the control group. The IFS and QFS were significantly reduced in the prone with backward extension and adduction with external rotation positions of the hip. The correlation coefficients of the IFI test and long-stride walking (LSW) test were -0.621 and -0.715 for IFS and -0.653 and -0.696 for QFS, respectively.Conclusions: In this study, the mechanism of the IFI-specific clinical examination (IFI and LSW tests) was verified by triaxial dynamic MR imaging of the hip joint, which provided a dynamic imaging basis for the clinical application of the IFI-specific impingement test. The IFI impingement test can be used as a specific clinical test for IFI screening.

“…A recent systematic review on the treatment strategies for ischiofemoral impingement revealed that several treatment strategies had been reported for ischiofemoral impingement, and most of them had good short- to medium-term outcomes with a low rate of complications. However, there were no comparative studies to assess the superiority of one technique over another, thus further research was recommended [ 26 , 27 ]. Hence, due to the limited understanding of the condition, preventive action in sports and the mechanism behind success of conservative treatment remains unelicited.…”

The risk for ischiofemoral impingement has been mainly related to a reduced ischiofemoral distance and morphological variance of the femur. From an evolutionary perspective, however, there are strong arguments that the condition may also be related to sexual dimorphism of the pelvis. We, therefore, investigated the impact of gender-specific differences in anatomy of the ischiofemoral space on the ischiofemoral clearance, during static and dynamic conditions. A random sampling Monte-Carlo experiment was performed to investigate ischiofemoral clearance during stance and gait in a large (n = 40 000) virtual study population, while using gender-specific kinematics. Subsequently, a validated gender-specific geometric morphometric analysis of the hip was performed and correlations between overall hip morphology (statistical shape analysis) and standard discrete measures (conventional metric approach) with the ischiofemoral distance were evaluated. The available ischiofemoral space is indeed highly sexually dimorphic and related primarily to differences in the pelvic anatomy. The mean ischiofemoral distance was 22.2 ± 4.3 mm in the females and 29.1 ± 4.1 mm in the males and this difference was statistically significant (P < 0.001). Additionally, the ischiofemoral distance was observed to be a dynamic measure, and smallest during femoral extension, and this in turn explains the clinical sign of pain in extension during long stride walking. In conclusion, the presence of a reduced ischiofemroal distance and related risk to develop a clinical syndrome of ischiofemoral impingement is strongly dominated by evolutionary effects in sexual dimorphism of the pelvis. This should be considered when female patients present with posterior thigh/buttock pain, particularly if worsened by extension. Controlled laboratory study.

“…Although these pathologies are all located in the deep gluteal space, 3 SNE, IFI, and proximal hamstring tears are unique entities. [4][5][6][7][8] Kay et al 6 performed a systematic review that assessed complications following SNE surgical management. These authors reported that the endoscopic alternative resulted in an astonishingly low incidence of complications with a rate less than 1%.…”

Advancements in hip arthroscopy are astounding. Circumferential labral reconstruction, labral augmentation, and capsular reconstruction are valuable tools. Beyond the "comfort zone" of the hip intra-articular realm, new frontiers include the peritrochanteric space, and a similarity to the subacromial space of the shoulder makes the transition attainable. In contrast, the subgluteal space is seen as outside the box. Sciatic nerve entrapment (SNE), ischiofemoral impingement (IFI), and tears of the proximal origin of the hamstring are among the subgluteal space pathologies. Clinical assessment of deep gluteal syndrome, defined as nondiscogenic sciatic nerve entrapment, can be particularly difficult but is critical and one of the skills that we as hip sports surgeons need to master. The respective treatments for SNE, IFI, and hamstring tears are nerve decompression, lesser trochanteric resection, and hamstring repair. Complications can occur, most commonly temporary injury of the sciatic nerve and permanent injury of the posterior femoral cutaneous nerve. While all located in the deep gluteal space, SNE, IFI, and proximal hamstring tears are unique entities. When thinking outside the box, it's important to consider the complicated contents of Pandora's box.
