关节镜下四袢与双袢固定修复急性肩锁关节Rockwood V型脱位疗效对比研究

目的对比评估双骨道四袢与单骨道双袢固定修复急性肩锁关节Rockwood Ⅴ型脱位疗效。 方法回顾性分析2010年5月至2016年5月于深圳大学第一附属医院接受关节镜下双骨道四袢与单骨道双袢固定修复急性肩锁关节Rockwood Ⅴ型脱位的所有患者,其中入选82例手术患者,四袢双骨道组与双袢单骨道组各41例。术后2年内随访观察患者的视觉模拟评分（visual analogue scale,VAS） 、患者恢复运动时间、恢复运动患者数量、Constant功能评分、Karlsson肩锁关节功能评分,并通过影像学观察评估喙锁关节和肩锁关节的间隙。 结果术后2年内末次随访X线片显示四袢双骨道组患侧平均喙锁关节和肩锁关节的间隙与双袢单骨道组对比明显减小,且差异具有统计学意义（P<0.05）;双袢单骨道组患者健侧平均喙锁关节和肩锁关节的间隙与患侧对比明显减小,且差异具有统计学意义（P<0.05）;然而四袢双骨道组患者健侧平均喙锁关节和肩锁关节的间隙与患侧对比差异无统计学意义（P>0.05）。两组患者术后末次随访患肢疼痛均有明显减轻,术前与术后VAS评分对比差异具有统计学意义,两组组间对比差异无统计学意义。四袢双骨道组重返运动的时间较双袢单骨道组明显缩短,重返患者数目明显多于双袢单骨道组,且Constant功能评分、Karlsson肩锁关节功能评分均明显优于双袢单骨道组,差异均具有统计学意义（P<0.05）。四袢双骨道组并发症明显少于双袢单骨道组。 结论采用关节镜下双骨道四袢固定治疗Rockwood V型脱位,方法固定可靠,并发症少,较双袢单骨道固定效果更佳,是治疗急性肩锁关节Rockwood V型脱位损伤较好的方法。     

Distraction arthroplasty in osteoarthritis of the foot and ankle

Post-traumatic osteoarthritis(PTOA) is a complex and painful problem in the foot and ankle.Ninety percent of osteoarthritis cases in the foot and ankle can be classified as post-traumatic.PTOA can affect any of the 33 joints in the foot and the ankle.Distraction arthroplasty is a method for treatment of early arthritic joints without fusing or replacing them and its effectiveness has been well documented.The purpose of this case series is to present our successful experiences and positive results using distraction arthroplasty to treat PTOA in the ankle,subtalar,first metatarsophalangeal,and second tarsometatarsal joints,and to present distraction arthroplasty as a viable alternative to invasive joint sacrificing procedures such as arthrodesis or arthroplasty.Distraction Arthroplasty effectively and safely treats PTOA and improves the stability of joints in the Foot and Ankle.Additionally,the use of bone marrow aspirate concentrate as an adjuvant can improve the long-term functional and structural outcomes of the joint,and can prolong the need for further,more aggressive surgical interventions such as fusion or arthroplasty.     

关节镜下AR缝合枪缝合外侧半月板撕裂的临床疗效观察

目的探讨分析外侧半月板体部层裂或纵向撕裂在关节镜下使用AR缝合枪全内垂直褥式缝合的临床疗效。方法本研究回顾性分析2017年1月至2017年12月,我科收治膝关节单纯外侧半月板体部撕裂(层裂或纵向撕裂)36例患者的临床资料,男13例,女23例;年龄16-41岁,平均(26.50±2.50)岁。36例患者中盘状半月板损伤7例。术中将撕裂外侧半月板修切白区内缘,保留红白区交界,体部层裂或纵裂新鲜化处理后行AR缝合枪全内垂直褥式缝合。术后根据Barrett标准门诊随访判断半月板的体部缝合临床愈合情况,采用重复测量方差分析比较不同时间视觉模拟评分(visual analogue scale,VAS)、膝关节主观功能评分(IKDC 2000评分)、膝关节功能评分(Lysholm评分)的差异来评估手术缝合疗效。术后12个月行膝关节MRI检查观察缝合部位恢复情况。结果本组36例患者均获随访,随访时间12-18个月,平均(15.0±2.3)个月。术后未出现感染、神经血管损伤、二次手术等并发症。根据Barrett标准评价,本组患者均获得半月板临床愈合。术后3个月、6个月、12个月的VAS评分为(1.10±0.12)分、(1.00±0.21)分、(0.90±0.32)分低于术前的(5.20±1.80)分,IKDC2000评分为(82.34±3.15)分、(85.34±5.17)分、(87.34±4.18)分高于术前的(40.51±5.54)分,Lysholm评分为(87.38±6.18)分、(88.52±4.19)分、(90.34±4.22)分高于术前的(42.11±6.82)分,差异具有统计学意义(P<0.05)。术后12个月复查MRI结果,34例(94.44%)甲级愈合,1例(2.78%)乙级愈合,1例(2.78%)未愈合。结论关节镜下采用AR缝合枪行全内垂直褥式缝合膝关节外侧半月板体部撕裂(层裂或纵裂),能有效缓解疼痛、提高患肢功能活动、促进半月板愈合,同时具有操作简单、并发症少等优势,经中短期临床随访其临床疗效显著,远期疗效需进一步随访追踪。     

The relationship of three-dimensional joint space width on weight-bearing CT with pain and physical function

Limitations of plain radiographs may contribute to poor sensitivity in the detection of knee osteoarthritis and poor correlation with pain and physical function. Three-dimensional (3D) joint space width (JSW), measured from weight-bearing computed tomography (CT) images, may yield a more accurate correlation with patients’ symptoms. We assessed the cross-sectional association between 3D JSW and self-reported pain and physical function. Five hundred twenty eight knees (57% women) were analyzed from Multicenter Osteoarthritis Study participants. An upright weight-bearing CT scanner was used to acquire bilateral, weight-bearing, fixed-flexion images of the knees. A 3D dataset was reconstructed from cone beam projections and JSW was calculated across the joint surface. The percentages of the apposed medial tibiofemoral joint surface with JSW less than 2.0 and 2.5 mm, respectively, were calculated. Pain and physical function were measured using Western Ontario and McMaster Universities Osteoarthritis Index. Participants who reported greater pain severity tended to have a greater joint area with JSW less than 2.0 mm (P = .07 for the highest vs the lowest tertile). Participants who reported greater functional limitations had a greater joint area with JSW less than 2.0 mm (P = .02 for the highest vs the lowest tertile). There appears to be an association between the medial tibiofemoral area with JSW less than 2.0 mm and pain and physical function.
