“…For the imaging of soft-tissue structures, which play a crucial role in the pathogenesis and development of clinical symptoms, MR imaging has emerged as an important tool. MRI of the hip remains challenging due to the complex geometry of the joint, its localization within the body, and the thin articular cartilage layers of the acetabulum and femur lying adjacent to one other [12-14]. In addition, to date, no dedicated hip coils exist resulting in reduced image quality when compared to other body regions such as the knee [12-14].…”

PURPOSE To assess the evolution of MR imaging findings in normal volunteers and subjects with hip osteoarthritis (OA) over 1.5 years described by the semi-quantitative Scoring Hip OA with MRI (SHOMRI) scoring system and their correlation with the evolution of clinical parameters. MATERIALS AND METHODS Hip MRI studies of 18 subjects with (Kellgren-Lawrence (KL) score 2/3; mean age 54.4±11.2 years; 27.8% women) and 36 controls without radiographic OA (KL 0/1; mean age 43.7±12.8 years; 50.0% women) were assessed at baseline and after 1.5 years by using SHOMRI, and their clinical status was evaluated by using Harris Hip Score and Hip Disability and Osteoarthritis Outcome Score (HOOS). Imaging and clinical parameters at baseline and their change over time were compared between groups using Mann Whitney U and Fisher’s exact tests. Spearman’s rank correlations and generalized linear models adjusted for age, sex, BMI and KL were used to assess associations between imaging and clinical findings. RESULTS At baseline, OA subjects had significantly higher SHOMRI total scores than controls (median (IQR), 12.5 (6–19.5) vs. 7 (4–13.5); p=0.024). Over 1.5 years, only the progression rate of subchondral cysts was significantly higher in OA subjects than in controls (16.7 vs. 0.0%; p=0.033), while no significant differences were found for any of the other SHOMRI subscales. Baseline bone marrow edema pattern (BMEP) was significantly associated with worsening pain (HOOS subscale; p=0.018) and hip-related quality of life (HOOS subscale; p=0.044). Progression of subchondral cysts was significantly associated with worsening symptoms other than pain (HOOS subscale, p=0.030). Baseline KL did not significantly correlate with worsening of any clinical symptoms (each, p>0.05). CONCLUSION In this relatively young study population without or with mild to moderate radiographic hip OA, only minimal differences were found between groups regarding the progression of hip abnormalities as assessed by SHOMRI over 1.5 years. However, BMEP predicted clinical worsening and subchondral cyst progression was associated with worsening symptoms. Although longer follow-up periods are required, this suggests that SHOMRI is a useful tool to monitor hip abnormalities and their progression longitudinally.

“…1,9,14,36 Another approach to studying the effects of FAI on hip joint health and function is through the use of magnetic resonance imaging (MRI) to assess articular cartilage degeneration in the FAI population. 11,19-21 Studies using MRI have demonstrated that there is a high incidence of hip joint cartilage abnormalities and labral lesions in the FAI population. 11,21 Gait assessments of patients with FAI during ADL may provide researchers and clinicians with the knowledge needed to detect this condition at an early stage and possibly reduce the need for surgical intervention.…”

Background Femoroacetabular impingement (FAI) is a morphological abnormality of the hip joint that results in functional impairments during various activities of daily living (ADL) such as walking. Purpose/Hypothesis The purpose of this study was to determine if lower extremity joint loading differed between patients with FAI and controls and to determine whether these altered biomechanical parameters were associated with intra-articular abnormalities. It was hypothesized that patients with FAI would exhibit altered lower extremity joint loading during walking when compared with healthy controls and that these altered joint loading patterns would be associated with intra-articular abnormalities. Study Design Controlled laboratory study. Methods Lower extremity kinetics was assessed during walking at a self-selected speed in 15 presurgical patients with FAI and 34 healthy controls matched for age and body mass index. All participants underwent unilateral hip magnetic resonance imaging (MRI) to assess hip joint abnormalities. Hip joint abnormalities were assessed using a semiquantitative MRI-based scoring system. Self-reported outcomes of pain and function were obtained using the Hip disability and Osteoarthritis Outcome Score (HOOS), and physical performance was measured using the 6-minute walk test (6MWT). Group differences were assessed using an independent t test and analysis of variance. In the patients with FAI, associations of joint kinetics with HOOS subscores and intra-articular abnormalities were assessed using the Pearson (r) and Spearman (ρ) correlation coefficients, respectively. Results Compared with the control group, the FAI group exhibited a significantly increased severity of acetabular (FAI: 1.87 ± 1.55; control: 0.47 ± 0.79; P < .001) and femoral (FAI: 3.27 ± 2.79; control: 1.21 ± 1.55; P = .002) cartilage abnormalities, increased levels of pain (FAI: 65.0 ± 18.8; control: 98.2 ± 3.4; P = .001), and reduced function (FAI: 67.2 ± 21.5; control: 98.9 ± 3.4; P < .001) but similar walking speeds (FAI: 1.55 ± 0.19 m/s; control: 1.63 ± 0.22 m/s; P = .20) and 6MWT performance (FAI: 628.0 ± 91.2 m; control: 667.2 ± 73.4 m; P = .13). The FAI group demonstrated increased hip flexion moment impulses (FAI: 0.14 ± 0.04 N·m·s/kg; control: 0.11 ± 0.03 N·m·s/kg; P = .03), peak ankle dorsiflexion moments (FAI: 1.64 ± 0.16 N·m/kg; control: 1.46 ± 0.31 N·m/kg; P = .04), and ankle dorsiflexion moment impulses (FAI: 0.39 ± 0.07 N·m·s/kg; control: 0.31 ± 0.07 N m s/kg; P = .01) compared with the control group. Within the FAI group, an increased hip flexion moment impulse during walking was significantly correlated with increased pain (r = −0.60, P = .03), decreased ADL (r = −0.57, P = .04), and increased severity of acetabular cartilage abnormalities (ρ = 0.82, P < .01). Conclusion Patients with FAI exhibited altered hip and ankle joint loading patterns during walking. These data suggest that patients with FAI demonstrate both local and distal joint alterations during walking and that hip joint loading is...

“…For the condylar cortex, MRI has been used to assess morphological changes, similar to computed tomography 14 , however, in these studies, the signal intensities of the articular disc and condylar cortex were not taken into account. Conversely, other joints, such as the knee and hip, are assessed by both the shape and signal intensity of the articular cartilage [15][16][17] .…”

: The purpose of this study was to clarify the validity of measuring the signal intensities of cortical bone CB and temporomandibular joint TMJ discs on magnetic resonance MR images for the diagnosis of TMJ disease. Two investigations were performed. In the rst investigation, MR images of 13 TMJs of volunteers were obtained using a multi spin-echo sequence. Echo time TE was increased from 10 msec to 200 msec in steps of 10 msec. The signal intensities of the CB of the condylar head, and the anterior AD and posterior PD bands of the TMJ disc were measured, and their attenuation patterns were compared. In the second investigation, clinical MR images of 30 TMJs from patients with suspected TMJ disorders were selected. Proton density-weighted images PDWIs and T2-weighted images T2WIs were obtained at TEs of 14 and 85 msec, respectively, using a double-echo fast spin-echo sequence. The signal intensities of CB, AD, and PD were measured and compared with that of the external auditory meatus air using a Bonferroni test. AD and PD showed nearly identical signal intensity attenuation patterns. The signal intensities of AD and PD were lower than CB at TEs longer than 20 msec although they were higher at TEs shorter than 20 msec. Clinical PDWIs and T2WIs showed similar results. The signal intensities of CB, AD, and PD were signi cantly higher than the external auditory meatus air in both PDWIs and T2WIs. CB and TMJ discs show characteristic signal intensities, suggesting that the signal intensity measurement of these structures is valid.
