| 1 | Bone–cartilage crosstalk:a conversation for understanding osteoarthritis显示文摘Although cartilage degradation is the characteristic feature of osteoarthritis(OA), it is now recognized that the whole joint is involved in the progression of OA. In particular, the interaction(crosstalk) between cartilage and subchondral bone is thought to be a central feature of this process. The interface between articular cartilage and bone of articulating long bones is a unique zone, which comprises articular cartilage,below which is the calcified cartilage sitting on and intercalated into the subchondral bone plate. Below the subchondral plate is the trabecular bone at the end of the respective long bones. In OA, there are welldescribed progressive destructive changes in the articular cartilage, which parallel characteristic changes in the underlying bone. This review examines the evidence that biochemical and biomechanical signaling between these tissue compartments is important in OA disease progression and asks whether such signaling might provide possibilities for therapeutic intervention to halt or slow disease development. | David M Findlay Julia S Kuliwaba | 2016 | Bone Research2016，4，3： | 27 |
| 2 | Role of polyethylene particles in peri-prosthetic osteolysis:A review显示文摘There is convincing evidence that particles produced by the wear of joint prostheses are causal in the periprosthetic loss of bone,or osteolysis,which,if it progresses,leads to the phenomenon of aseptic loosening.It is important to fully understand the biology of this bone loss because it threatens prosthesis survival,and loosened implants can result in peri-prosthetic fracture,which is disastrous for the patient and presents a difficult surgical scenario.The focus of this review is the bioactivity of polyethylene(PE)particles,since there is evidence that these are major players in the development and progression of osteolysis around prostheses which use PE as the bearing surface.The review describes the biological consequences of interaction of PE particles with macrophages,osteoclasts and cells of the osteoblast lineage,including osteocytes.It explores the possible cellular mechanisms of action of PE and seeks to use the findings to date to propose potential nonsurgical treatments for osteolysis.In particular,a nonsurgical approach is likely to be applicable to implants containing newer,highly cross-linked PEs(HXLPEs),for which osteolysis seems to occur with much reduced PE wear compared with conventional PEs.The caveat here is that we know little as yet about the bioactivity of HXLPE particles and addressing this constitutes our next challenge. | Gerald J Atkins David R Haynes Donald W Howie David M Findlay | 2011 | World Journal of Orthopedics2011，2，10： | 11 |

| 6 | 颈动脉内膜切除术显示文摘背景:自从证实颈动脉内膜切除术(CEA)是预防卒中的一种有效方法以来,人们对其最佳的适应证和治疗方法以及如何与颈动脉血管成形和支架置入术(CAS)进行比较重新产生了兴趣。本文对上述问题、颈动脉狭窄的检查以及审核和报道CEA结果的作用进行探讨。检查方法:考虑CEA治疗的患者应该进行CT或MPI脑影像学检查以证实脑梗死和排除占位性病变。颈动脉的检查从超声开始,然后进行高质量MPA或CTA,如果结果一致,就能够计划进行治疗而不必进行导管血管造影。另一种同样可以接受的方法是直接从超声到导管血管造影检查,后者仍然是评价颈动脉的金标准。适应证:最适合接受CEA治疗的患者为由于颈动脉重度狭窄(70%~90%)引起短暂性脑缺血发作或非致残性卒中症状者,允许的最大卒中和病死率为6%。尚不确定的CEA候选者为狭窄程度为50%~69%的有症状患者以及狭窄≥60%的无症状患者,但如果在其他危险因素(与颈动脉斑块和某些患者特征均有关)的基础上进行仔细选择的话,有些患者可能从手术中获益。只有在严重并发症发生率极低的情况下(3%或更低),无症状患者才能获益。那些颈动脉狭窄〈50%的有症状患者或狭窄〈60%的无症状患者以及那些内科状况或神经系统状况不稳定的患者不适合进行CEA治疗。技术:CEA可在局麻或全麻下进行,对于后者,在颈动脉夹闭时必须有许多检测技术来评价脑灌注。当监测不是强制性并且没有哪一种监测技术被明确证实优于其他技术时,脑电图(EEG)是最常使用的。外翻式CEA是外科技术的一种变异,有些证据表明更加广泛应用的补片闭合可能会降低手术期急性卒中风险和狭窄复发的长期风险。CAS:随着经验的增加,这种侵袭性较小的血管内技术仍在持续发展。一些经验丰富的治疗专家已经在病例系列研究中报道了极好的结果,大量的随机试验正在对CAS和CEA进行比较。然而,目前把CAS列为替代CEA的常规治疗手段还为时过早。审核:业已证实,通过定期向手术医师反馈对CEA适应证和结果的审核情况能够显著改善这种手术的操作。推荐同时在当地和地区水平对CEA进行审核。 | J Max Findlay B Elaine Marchak David M Pelz Thomas E Feasby 杨芳(译) 杨斌(译) | 2005 | 中华脑血管病论坛2005，3，5： | 0 |
| 7 | Collecting a comprehensive evidence base to monitor fracture rehabilitation: A case study显示文摘AIM: To determine the feasibility and potential role of combining radiostereometric analysis(RSA), gait analysis and activity monitoring in the follow-up of fracture patients.METHODS: Two patients with similar 41B3 tibial plateau fractures were treated by open reduction internal fixation augmented with impaction bone grafting and were instructed to partial weight bear to 10 kg for the first six postoperative weeks. Fracture reduction and fixation were assessed by postoperative computer tomographic(CT) scanning. Both patients had tantalum markers inserted intra-operatively to monitor their fracture stability during healing using RSA and differentially loaded RSA(DLRSA) at 6 and 12 wk postoperatively. Gait analyses were performed at 1, 2, 6, and 12 wk postoperatively. Activity monitors were worn for 4 wk between the 2 and 6 wk appointments. In addition to gait analysis, knee function was assessed using the patient reported Lysholm scores, and doctor reported knee range of motion and stability, at 6 and 12 wk postoperatively.RESULTS: There were no complications. CT demonstrated that both fractures were reduced anatomically. Gait analysis indicated that Patient 1 bore weight to 60% of body weight at 2 wk postoperative and 100% at 6 wk. Patient 2 bore weight at 10% of body weight to 6 wk and had very low joint contact forces to that time. At 12 wk however, there was no difference between the gait patterns in the two patients. Patient 1 increased activities of moderate-vigorous intensity from 20 to 60 min/d between 2 and 6 postoperative weeks, whereas Patient 2 remained more stable at 20-30 min/d. The Lysholm scores were similar for both patients and did not improve between 6 and 12 wk postoperatively. DLRSA examination at 12 wk showed that both patients were comfortable to weight bear to 80 kg and under this weight the fractures displaced less than 0.4 mm. RSA measurements demonstrated over time fracture migrations of less than 2 mm in both cases. However, Patient 2, who followed the postoperative weight bearing instructions most closely, displaced less(0.3 mm vs 1.6 mm). CONCLUSION: This study demonstrates the potential of using a combination of RSA, gait analysis and activity monitoring to obtain a comprehensive evidence base for postoperative weight bearing schedules during fracture healing. | Stuart A Callary Dominic Thewlis Alex V Rowlands David M Findlay Lucian B Solomon | 2013 | World Journal of Orthopedics2013，4，4： | 0 |
