ABSTRACT
OBJECTIVE@#Meta-analysis was used to compare the clinical efficacy of high tibial osteotomy(HTO) and unicondylar arthroplasty (UKA) in the treatment of medial compartment osteoarthritis (MIOA) and provide a better surgical choice for patients with MIOA.@*METHODS@#The Cochrane Library (Issue 6, 2017), PubMed, Ovid, ELSIVE, CNKI and Wanfang databases were searched by a computer. Literatures on HTO and UKA for MIOA from January 1, 1970 to June 30, 2017, including complications, knee joint score, knee mobility, revision rate and excellent and good rate, were searched and screened out according to the inclusion criteria, and strict quality evaluation was carried out. RevMan 5.0 software provided by Cochrane collaboration network was used to conduct the meta-analysis of the included research results and to test the heterogeneity of the data.@*RESULTS@#Total 13 articles met the inclusion criteria, and the total sample size was 1 043. Among them, 462 were HTO treatment group and 581 were UKA treatment group. By comparison between HTO treatment group and UKA treatment group, there were significant differences in the contralateral deterioration rate[WMD=3.21, 95%CI(1.13, 9.10)], pre-operative knee range of motion[WMD=6.55, 95%CI(1.44, 11.66)], Lysholm knee score[WMD=-3.15, 95%CI(-4.77, -1.53)], complications[WMD=2.78, 95%CI(1.52, 5.11], revision rate[WMD=1.81, 95%CI(1.17, 2.80)], the rate of excellent and good[WMD=0.49, 95%CI(0.30, 0.80)], and femorotibial angle changes[WMD=-2.37, 95%CI, (-3.63, -1.11)](0.05).@*CONCLUSIONS@#Based on the limited data, high tibial osteotomy is a better choice for the treatment of medial compartment osteoarthritis in the comparison of short and medium-term clinical outcomes, and long-term clinical outcomes may need further study.

<p><b>OBJECTIVE</b>To explore clinical outcomes of director for sustentaculum tali screwing for fixing sustentaculum tali of calcaneus.</p><p><b>METHODS</b>From May 2012 to October 2013, totally 50 patients (60 feet) with calcaneal fractures were analyzed, and divided into director for sustentaculum calcaneous tali screwing treatment group (group A) and ordinary screwing group(group B). In group A, there were 25 patients, including 22 males and 3 females, aged from 17 to 75 years old with an average of (45.08±11.98) years; according to Sanders classification, 9 feet were type II, 16 feet were type III, and 7 feet were type IV. In group B, there were 25 patients, including 20 males and 5 females, aged from 19 to 78 years old with an average of (46.36±15.74) years; according to Sanders classification, 8 feet were type II, 13 feet were type III, and 7 feet were type IV. Radiological change, operative time, postoperative complications were observed and compared, Maryland scoring at 1 year after operation was applied to evaluate clinical outcomes.</p><p><b>RESULTS</b>Fifty patients were followed up, group A was followed up from 12 to 24 months with an average of (17.72±4.08) months;while group B was followed up from 12 to 24 months with an average of (18.68±3.40) months;there was no significant difference between two groups in following-up time(>0.05). There were significant difference in operative time, complications and fluoroscopy times between two groups(<0.05). There were significant difference in Böhler angle and Gissanes angle between two groups before and after operation(<0.05). Maryland score at 1 year after operation in group A was (84.94±12.75) and (76.96±15.32) in group B, had significant meaning between two groups (<0.05).</p><p><b>CONCLUSIONS</b>Fixation of sustentaculum tali of calcaneus aided by director for sustentaculum tali screwing, has advantages of less operative time, fluoroscopy times, incidence of complications and good recovery of function, which could provide a new aiding method for treating intra-articular calcaneal fractures.</p>
ABSTRACT
<p><b>OBJECTIVE</b>To explore 5-year survival rate, local recurrence and metastasis rate of limb salvage and amputation for patients with local Enneking II osteosarcoma by Meta-analysis.</p><p><b>METHODS</b>From January 1, 1970 to December 1, 2015, Subject term and keywords about limb salvage and amputation for local Enneking II osteosarcoma with pathological fracture were searched from Cochrane, PubMed, Ovid, Spinger Link, Embase, CNKI and WanFang database foundation. Literature confirm with inclusion criteria were choose and quality evaluation were performed. RevMan 5.0 software from Cochrane collaboration was used to perform Meta-analysis. Local recurrence, 5-year survival rate and odds ratio of transfer risk were compared between limb salvage and amputation group.</p><p><b>RESULTS</b>Ten literatures confirm with inclusion criteria were included, and total sample size was 453. There were 315 patients in limb salvage group and 138 patients in amputation group. Five-year survival rate in amputation group was lower than that of limb salvage group [OR=2.88, 95%CI(1.40, 5.93)], however metastasis rate in limb salvage was less than that of amputation group [OR=0.43, 95%CI(0.20, 0.94)];there were no significant differences in local recurrence between two groups [OR=1.47, 95%CI (0.73, 2.97)]. Functional rehabilitation in limb salvage group was better than that of amputation group by MSTS systematic review.</p><p><b>CONCLUSIONS</b>Limb salvage as an alternative in treating local Enneking II osteosarcoma with pathological fracture does not greatly increase risk of local recurrence or 5-year overall survival rate compared with amputation group, and has a lower risk of metastatic occurrence.</p>
ABSTRACT
<p><b>OBJECTIVE</b>To search all studies that had been published in the world with regarding to the effectiveness of the extent of intralesional curettage and wide excision for recurrence rate and complications and comparative functional outcomes in patients with giant cell tumours (GCT) of the distal radius and analyze them which were in high quality by means of Meta analysis, in order to give some evidences for the choice of method dealing with giant cell tumors GCT in surgery.</p><p><b>METHODS</b>Cochrane central register of controlled trials(Issue 8 2014), PubMed(1970-01-01/2013-01-01), Ovid (1970-01-01/2013- 01-01), Elsevier (1970-01-01/2013-01-01), CNKI (1970-01-01/2013-01-01) were searched. Including intralesional curettage and wide excision were performed to treat giant cell tumors (GCTs) of the distal radius in the literatures, selecting on meet eligibility in the standard literatures underwent strict quality assessment. The Meta-analysis was performed with software RevMan5.0 from the Cochrane collaboration. Additionally, the analysis checked the heterogeneity of data. The effectiveness of the extent of intralesional curettage and wide excision for recurrence rate and complication in patients with giant cell tumours of the distal radius were evaluated and Odds Ratio was calculated.</p><p><b>RESULTS</b>Seven relevant articles were identified involving total 163 cases. Among them, 92 cases were intralesional curettage (PMMA, n = 54; bone graft, n = 33; no PMMA or bone grafts, n = 5) and 71 cases were wide excision. The patients in the intralesional curettage group had a higher recurrence rate [OR = 3.87, 95% CI (1.42, 10.53)],especially for Campanacci grade 3 GCTs [OR = 10.12, 95% CI (1.57, 65.27)], yet fewer major complications [OR = 0.13, 95% CI (0.04, 0.40)] than the wide excision group. The use of PMMA versus bone graft did not affect the recur- rence rate [OR = 0.96, 95% CI (0.26, 3.56)]. By selecting the system evaluation of MSTS, the VAS and dynamometer, the result showed that the intralesional curettage group was equivalent or preferable to wide excision in terms of function rehabilitation.</p><p><b>CONCLUSION</b>Based on data obtained from the limited number of studies available, intralesional curettage appears to be moreappropriate for the treatment of local lesions (Grade 1 and 2) than Grade 3 GCTs of the distal radius. Moreover, PMMA was not additionally effective as an adjuvant, the intralesional curettage group was found to be equivalent or preferable to wide excision in terms of function rehabilitation.</p>

<p><b>OBJECTIVE</b>To evaluate the short term clinical effects and surgery methods of the total hip arthroplasty (THA)for the treatment of Crowe type IV congenital dysplasia of hip (CDH) in adults.</p><p><b>METHODS</b>From March 2013 to March 2015, 20 patients (20 hips) with Crowe type IV CDH in adults were underwent THA, including 4 males and 16 females, with an average age of 52 years old ranged from 32 to 68 years old. All the cementless acetabular cups were placed at the original anatomic location. S-ROM prosthesis was adopted together with subtrochanteric transverse osteotomy in femoral side. All the patients were evaluated by using the Modified Harris Hip Score. Radiographic evaluations were made preoperatively and during follow up.</p><p><b>RESULTS</b>The incisions were healed by first intention. There was no hip dislocation events and venous thrombosis occurred. All patients were followed up for 8 to 60 months with an average of 38.1 months. Postoperative X ray films showed all acetabular prosthesis were in true acetabulum. No nonunion and loosening were found in all patients. Harris score at final follow up improved from preoperative 50.90±9.35 to postoperative 90.25±3.16. The difference was statistically significant (<0.05). There were 1 patient with femoral split fracture, 1 patient with nerve injury, 1 patient with heterotopic ossification of Brooker I. The hip function of all patients was good, the pain was disappeared.</p><p><b>CONCLUSIONS</b>THA with S-ROM prosthesis and subtrochanteric osteotomy is an effective method for the treatment of Crowe type IV CDH in adults. The recent clinical curative effect is satisfied.</p>
