Introduction: In patients with painful hip joint, femoroacetabular impingement is a relatively frequently diagnosed condition. Study aim: The aim of the study was to present the anatomy, biomechanics and pathomechanism of femoroacetabular impingement, surgical diagnostics and treatment, as well as physiotherapeutic procedures, and to provide answers to the following questions: 1. What are the causes of femoroacetabular impingement development and what is its most common form? 2. What are the clinical and imaging diagnosis of femoroacetabular impingement based on? 3. What are the goals of physiotherapeutic treatment in the treatment of patients with postoperative femoroacetabular impingement? Material and method: Current professional literature was analysed based on a review of Internet databases, including Pubmed and Google Scholar. Results: From the abovementioned Internet databases, 30 items from the current profession-al literature on the analysed variables were identified. Conclusions: The reasons for the development of femoroacetabular impingement are com-plex, including developmental disorders of the hip joint or its chronic overload. Its most common form is mixed type. The basic imaging test used is anterior-posterior X-ray, while clinical assessment is based on anterior-posterior impingement test. Physiotherapy should be individually tailored and focused on improving range of motion and muscle strength of the hip joint.

Femoroacetabular impingement (FAI) is increasingly recognized as a risk factor for early hip degeneration in young active patients. The diagnosis depends on clinical examination and proper imaging that should be able to identify abnormal and sometimes subtle morphological changes. Labral tears and cartilage lesions rarely occur without underlying bone abnormalities. Surgical approaches to treat FAI are increasing significantly worldwide, even without a clearly defined consensus of what should be accepted as the standard imaging diagnosis for FAI morphology.Hip abnormalities encompass many variations related to the shape, size, and spatial orientation of both sides of the joint and can be difficult to characterize if adequate imaging is not available.This article presents a comprehensive review about the information orthopaedic surgeons need to know from radiologists to plan the most rational approach to a painful hip resulting from a mechanical abnormality.

Objective: To explore the evaluation indicators of X-ray radiographs for femoroacetabular impingement (FAI) syndrome, and to propose therapeutic plans for FAI syndrome by using X-ray radiographs. Methods: From June 2016 to May 2018, patients who were diagnosed as FAI syndrome by hip joint anteroposterior radiographs in Second Yinzhou District Hospital were selected as research objects. After screening, the surgical treatment group included 52 cases, totally. Another 30 healthy adults who received X-ray radiography were included as the control group. Each included patient underwent minimally invasive surgery under hip arthroscopy. The efficacy indicators were evaluated, and the data were statistically analyzed. Results: By analyzing the basic data of the subjects, it was found that there was no significant difference in gender and body mass index between the healthy people and FAI patients (P > 0.05), but the VAS and Harris scores of 7d, 30d, 90d, and 180d after surgery were significantly higher than those before the operation, and with the prolongation of the treatment time, the scores increased continuously, the difference had statistical significance (P < 0.05). By analyzing patients' knee joint mobility, it was found that after therapy, the flexion, pronation, abduction, and extension of knee joint at 30d, 90d, and 180d were distinctly increased compared with those before therapy. Also, the difference had statistical significance (P < 0.05) with the treatment time increasing; the X-ray films of hip joint of the subjects were observed, and it was found that there were healthy people, clamp type FAI, and cam type FAI three typical kinds. There were significant differences in the angle, eccentricity, depth of acetabulum, coverage rate of acetabulum, and CE angle among cam type patients, clamp type patients, and healthy people (P < 0.05). Conclusion: The research in this study found that when using the X-ray radiographs to determine the FAI syndrome, the differences between the classification of FAI symptoms and the healthy adults were obvious. In addition, the knee joint gradually recovered significantly in the range of movement (RM) after treatments, thereby providing experimental basis for diagnosing and treating the FAI syndrome in the later clinical stage.

Abstract Purpose The application of the anatomical parameters of the contralateral hip joint to guide the preoperative template of the affected side relies on the bilateral hip symmetry. We investigated the bilateral hip symmetry and range of anatomical variations by measurement and comparison of bilateral hip anatomical parameters. Methods This study included 224 patients (448 hips) who were diagnosed with osteoarthritis (OA) and avascular necrosis (AVN) of the femur head, and underwent bilateral primary total hip arthroplasty (THA) in our hospital from January 2012 to August 2020. Imaging data included 224 patients X-ray and 30 CT data at the end of the cohort. Anatomical parameters, including the acetabular abduction angle and trochanteric height, were measured using the Noble method. Postoperative measurements included stem size, difference of leg length and offset. Results Except for the isthmus width, there were no significant differences in the anatomical morphology of the hip joint. Among the demographic factors, there was a correlation between body weight and NSA. Among various anatomical parameters, a correlation was present between medullary cavity widths of T + 20, T, and T − 20. The difference in the use of stem size is not due to the morphological difference of bilateral medullary cavity, but due to the different of 1- or 2-stage surgery. Conclusion Bilateral symmetry was present among the patients with normal morphology of the hip medullary cavity, theoretically confirming the feasibility of structural reconstruction of the hip joint using the hip joint on the uninjured side. Additionally, the difference in the morphology of the hip medullary cavity is not present in a single plane but is synergistically affected by multiple adjacent planes.

Background: Radiography is the initial imaging modality used to evaluate femoroacetabular impingement (FAI), and diagnostic radiographic findings are well-established. However, the prevalence of these radiographic findings in patients with hip pain is unknown. Purpose: The purpose was 3-fold: (1) to determine the overall prevalence of radiographic FAI deformities in young patients presenting with hip pain, (2) to identify the most common radiographic findings in patients with cam-type FAI, and (3) to identify the most common radiographic findings in patients with pincer-type FAI. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A geographic database was used to identify patients aged 14 to 50 years with hip pain between the years 2000 to 2016. The following were evaluated on radiographs: cam type: typical pistol grip deformity, alpha angle >55°; pincer type: crossover sign (COS), coxa profunda or protrusio acetabuli, lateral center edge angle (LCEA) ≥40°, Tönnis angle <0°; and mixed type: both cam- and pincer-type features. Posterior wall sign (PWS) and ischial spine sign (ISS) were also evaluated. The prevalence of each was determined. Descriptive statistics were performed on all radiographic variables. Results: There were 1893 patients evaluated, and 1145 patients (60.5%; 1371 hips; 374 male and 771 female; mean age, 28.8 ± 8.4 years) had radiographic findings consistent with FAI. Of these hips, 139 (10.1%) had cam type, 245 (17.9%) had pincer type, and 987 (72.0%) had mixed type. The prevalence of a pistol grip deformity and an alpha angle >55° was 577 (42.1%) and 1069 (78.0%), respectively. The mean alpha angle was 66.9°± 10.5°. The prevalence of pincer-type radiographic findings was the following: COS, 1062 (77.5%); coxa profunda, 844 (61.6%); ISS, 765 (55.8%); PWS, 764 (55.7%); Tönnis angle <0°, 312 (22.8%); LCEA ≥40°, 170 (12.4%); and protrusio acetabuli, 7 (0.5%). Conclusion: The overall prevalence of radiographic findings consistent with FAI in young patients with hip pain was 60.5%. Radiographic findings for mixed-type FAI were the most prevalent. The most common radiographic finding for cam-type FAI was an alpha angle >55°. The most common radiographic finding for pincer-type FAI was the COS.

The purpose of the work was to detect clinical-morphologic correlative dependences in patients with clinically marked femoroacetabular impingement (FAI) syndrome basing on the study of pathomorphologic changes in hip joint tissues, semiquantitative quantification of pathologic changes intensity, frequency analysis of their occurrence in nosologic groups of comparison. Study was performed on specimens of hip joint tissues - femoral head, acetabulum, acetabular labrum and joint capsule, resected during indicated corrective surgeries for femoral head aseptic necrosis and juvenile epiphysiolysis. Clinical-morphologic study revealed various pathologic changes: dystrophic-destructive, ischemic-necrotic and productive-inflammatory. In patients with FAI syndrome clinical and morphologic correlative dependences varied by absolute value, sign and degree of reliability of association coefficient parameters, i.e. groups of patients with certain nosologic units retained the peculiarities of rate and characteristics proportions in correlative dependences
