Objective To assess the image findings of femoroacetabular impingement (FAI).Methods Image findings of 9 patients with surgically proved femoroacetabular impingement were retrospectively reviewed for characteristic image findings of FAL All 9 patients underwent X-ray examinations and MRI of affected hip, and 1 patient underwent MR arthrography (MRA) additionally. Results X-ray examinations of all 9 patients showed bump at femoral head-neck junction or overcoverage of the acetabula.MRI showed various degrees of injury of anterosuperior labrum in all 9 patients. The injuries were stage Ⅰ A in2 cases, stage Ⅰ B in3, stage ⅡA in2, and stage ⅡB in 2. MRA of the case showed tears of anterosuperior labrum, with contrast media entering into the teared labrum. There were sclerosis and cystic degeneration of subchondral bone of femoral head in 2 cases, and these findings were confirmed as cartilage delamination by surgery. Conclusions MRI can display the injures of labrum and articular cartilage, which is helpful to the early diagnosis of FAI.

OBJECTIVETo study the effectiveness of pie-crusting technique in improving the stiff knee.

METHODSFrom February 2012 to December 2013, 13 patients with stiff knee were reviewed retrospectively. There were 6 males and 7 females, ranging in age from 39 to 70 years old (averaged, 55.6 years old). Of the 13 cases, 8 patients had stiffness following fracture (comminuted tibial plateau fracture in 4, femoral supracondylar fracture in 3 and patellar fracture in 1), 5 patients had TKA-related stiffness.

RESULTSA follow-up lasted 8 to 12 months (mean 10 months)in 13 cases. The mean maximum flexion increased from (37 ± 6)° preoperatively to (52 ± 7)° after arthrolysis, and (108 ± 7)° after pie-crusting. At the final follow-up, mean maximum flexion was (105 ± 6)°. According to Judet evaluation system, 10 patients got an excellent result and 3 good. No major complications, such as extensor lag, skin necrosis, deep infection, dislocation of the patella or recurrent stiffness were found.

CONCLUSIONThe percutaneous technique of pie-crusting is a simple, minimally invasive and effective treatment for knee stiffness.

Objective:To compare the steam distillation( SD) and supercritical CO2 ( SFE-CO2 ) method in the extraction of vola-tile constituents from such 3 traditional Chinese drugs as cnidium monnieri, radix sileris and atractylodes lancea in compound Kuhuang prescription. Methods:Essential oil was extracted from the 3 traditional Chinese drugs by SD and SFE-CO2 method, respectively. The components were identified by GC-MS, and their relative contents were calculated with peak area normalization method. Results:To-tally 36 components were isolated and identified using SD extraction and 31 components were identified using SFE-CO2 extraction, a-mong them, 22 components were the same and their relative molecular weight mainly concentrated within 200-230. Conclusion: SFE-CO2 method can extract effective components from the 3 traditional Chinese drugs in compound Kuhuang prescription with higher selec-tivity, which is the more suitable extraction method for essential oil from the prescription.

Background and purpose:The quality of life and psychological status of the advanced cancer patients has been widely valued. This study aimed to analyze the psychological status of the advanced cancer patients and its influence factors.Methods:The patients who were hospitalized in the palliative care department of Fudan University Cancer Center from Sep. 2011 to Mar. 2013 were included in this study. Self-rating anxiety scale(SAS), self-rating depression scale (SDS), EORTC QLQ-C30, social support revalued scale and symptom checklist 90 (SCL-90) were recorded and analyzed.Results:Fifty-six patients were included in this study, 18 were depression and 24 were anxiety while 16 of them were depression together with anxiety. The patients were divided into 2 groups according to their psychological status. There’s no signiifcant difference between the age and the social support between the two groups, while the mental disorders group have lower scores on body function, role function, emotional function and social function. The mental disorders were positive correlated with the symptoms score while negative correlated with the quality of life.Conclusion:There’s a high ratio of mental disorders in advanced cancer patients, the symptom scores and quality of life are related to mental disorders. We should pay more attention to the patients who were suffered more from the illness or had lower QOL scores.

Objective To investigate the normal range of the femoral neck α-angle in normal Chinese adults and classify the morphology of the anterior femoral head-neck junction on CT-based images. Methods Six hundred and fifty-two adult patients (Bilateral: 459 patients, unilateral:193 patients) with the total of 1111 hips (552 left; 559 right, and 654 male; 457 female) without known diseases affecting the proximal femur or symptoms of femoroacetabular impingement (FAI) underwent 64-slice CT scanning for medical purpose with the hip included in the scan range. The volume CT data was used for further analysis in this study. Oblique sagittal plane images paralleling to the axis of the femoral neck were reconstructed with the volume CT data, the image through the middle of the femoral neck was chosen to measure α-angle with AutoCAD2006 software. The morphology of the anterior femoral head-neck junction was classified. Analysis of variance and t-test were performed with SPSS 15.0. Results The mean value of α-angle of all 1111 hips was 38. 2° ±5.3°. The normal range of α-angle in Chinese adults was 28°to 49°.The mean value of left and right α-angles were 38. 0° ±5. 3°and 38.4° ±5. 3° ,respectively, and there was no statistically significant difference between both sides (t = - 1. 231 ,P ＞ 0. 05 ). Males have greater α-angles than females 39. 2° ±5. 8 vs 36. 8° ±4. 1°, with t = -8. 180, P ＜0. 01. There was no statistically significant differences of the α-angles of the seven age groups (F = 1. 765, P ＞ 0. 05 ). In all 1111 proximal femora, 168 were classified as concave type, accounting for 15. 1%, with a mean α-angle of 31.2° ±2. 0°,726 were smooth type, accounting for 65.4%, with a mean α-angle of 37.4° ± 2. 4°, and 217 were flat type, accounting for 19.5%, with a mean α-angle of 46. 4° ±3. 8°. The differences of the α-angles of the three groups reached statistical significance ( F = 1636. 107, P ＜ 0. 01 ). Conclusions The morphology of anterior femoral head-neck junction can be classified into three types: concave type (type Ⅰ ), smooth type (type Ⅱ ) and flat type (type Ⅲ ). This classification could directly reflect α-angle, which helps to recognize the variation of the offset of anterior femoral head-neck junction. This study offers basic data for the diagnosis of FAI.

Objective To evaluate the feasibility of assessing osteoarthritis (OA) in hip dysplasia using 3D delayed gadolinium-enhanced MRI of cartilage (dGEMRIC).Methods Thirty-five hips in 20 patients with radiographic evidence of hip dysplasia underwent 3D-dGEMRIC scanning.Clinical symptoms were assessed with the Western Ontario and McMaster Universities Osteoarthritis ( WOMAC ) questionnaire.Radiographic measurement of lateral center-edge angle and T(o)nnis grading were performed on the X-rays.Hips of T(o)nnis grade 1were included in the group of hips with early OA,while the hips with no evidence of OA and without pain symptom were included in the group of hips with normal morphology.The 3D-dGEMRC scans were completed on a 1.5 T MR scanner.The data of 3D-dGEMRIC was reconstructed radically.The dGEMRIC indices were measured on six sites of periphery zones of hip cartilage on reconstructed images.The dGEMRIC indices among different groups were analyzed by non-parametric tests.The differences of dGEMRIC indices among six sites in the group of early OA or the group of normal morphology were analyzed by Wilcoxon test.Results The mean dGEMRIC indices of six sites were lower in group of T(o)nnis grade 1than in group of T(o)nnis grade 0 ( Z =- 2.149,P =0.032 ),and lower in group of T(o)nnis grade 2 than in group of T(o)nnis grade 1( Z =- 1.990,P =0.047 ).The dGEMRIC indices of the anterior site,anterosuperior site,superior-anterior site,and superior site were significantly different between the group of hips with early OA and the group of hips with normal morphology (Z =-2.333--2.041,all of the P values were lower than 0.05).In the group of hips with normal morphology,the dGEMRIC indices of superior-anterior site of hip were lower than superior site(P =0.028).In the group of hips with early OA,the dGEMRIC indices of superior-anterior site were lower than the other sites except for anterior-superior site ( Z =- 3.041- - 2.277,all of the P values were lower than 0.05 ).Conclusions 3 D-dGEMRIC might be a sensitive technique for detection of glycosaminoglycans alteration in early OA and staging of OA in hip dysplasia.Radial reconstruction could provide an accurate assessment of OA,and the results demonstrated that early cartilage alteration could be detected in the anterior to superior sites of hips,and the earliest cartilage alteration may occur in the superior-anterior site of hips.
