Objectives To investigate the characteristics of monosodium urate (MSU) deposition in patients with the first-episode of acute gouty arthritis (Gout) by using dual energy CT (DECT) imaging technique. Methods A total of 70 first-episode patients with acute Gout diagnosed in Peking University Third Hospital in 2019 were collected as the case group, including 69 males and 1 female, aged 17-65 (39±14) years. During the same period, a total of 15 male patients aged 19-56 (33±12) years were collected as the control group. They were admitted to the hospital due to sports injuries and were excluded from gout. The DECT data of the first-affected or the most painful joints of gout in the case group and the surgical ankle joints in the control group were retrospectively analyzed. The crystal morphology, volume and deposition location of MSU in the measured joints were evaluated and recorded, and the degree of MSU deposition in the joints of the first-episode patients with Gout and its coincidence with clinical symptoms ch helps to improve the early diagnosis rate of gout.Objective To compare clinical outcomes of microsurgical bilateral decompression via unilateral approach (MBDU) between trans longissimus and iliocostalis approach, a novel lateral paraspinal approach(LPA), and classic Wiltseapproach for single level degenerative lumbar stenosis. Methods LPA approach was researched by imaging measurement and cadaver anatomy. Retrospective analysis of a total 124 cases(male/female 75/49, aged(55±14) years) received single-level MBDU due to degenerative lumbar stenosis from 2016 to 2018 in Beijing Tiantan Hospital. Patients were categorized into two groups according to spinal canal morphology. selleck compound Group A trefoil shape (n=48), received MBDU via LPA; Group B round & oval shape (n=76), received MBDU via Wiltse approach. Clinical parameters, including visual analogue scale (VAS) of pain, OswestryDability Index (ODI), satisfaction rate were assessed before the operation and at the latest follow-up. The internal fixation and intervertebral fusion were evaluated by X-ray and CT.The data were compared with single sample t test between the two groups. Results The feasibility of trans longissimus and iliocostalis approach was proved by imaging measurement and anatomic study. The tube's maximum tilt angle in LPA group was 65°, and it was 40°in Wiltse group. There was no significantly difference in the operating time, bleeding and drainage volume between the two groups((120±27) min vs (115±32) min, (104±31) ml vs (110±41) ml, (50±15) ml vs (47±18) ml, respectively, t=1.246,-1.917,1.730,all P>0.05). In both groups, VAS and ODI scores significantly improved at the latest follow-up when compared with those before the operation (all P0.05). Conclusions LPA approachfor microsurgical bilateral decompression via unilateral approach (MBDU) in degenerative lumbar stenosis is safe and effective, it has advantages in direct vison of contralateral nerve root canal decompression for trefoil shaped spinal canal.Objective To investigate the application and efficacy of the one-stage total knee arthroplasty (TKA) of intra-articular compensation osteotomy in knee osteoarthritis(KOA) patients with extra-articular deformity (EAD). Methods A retrospective study of 9 patients with end-stage KOA and EAD undergoing one-stage TKA from January 2014 to December 2017 in the First Affiliated Hospital of Zhejiang Chinese Medical University was performed. There were 3 males and 6 females with an average age of 56 years(range, 19-77 years);5 cases of simple coronal deformity (varus 10°-27°, mean 18.2°), 3 cases of sagittal deformity (recurvatum15°-35°, mean 22.6°), 1 case combined with coronal and sagittal deformity (varus 16°, recurvatum 31°); hemophilia dysplasia in 1 case, fracture malformation in 8 cases. Main outcome measures included the mechanical axis, range of motion (ROM) and Hospital for Special Surgery Knee Score (HSS). Results The mean follow-up pe
