BACKGROUND:Three-dimensional (3D) printing technology exhibits a broad future in the orthopedics,especially exhibiting good guidance and auxiliary in the treatment of tibial plateau fractures.However,the related researches are few,and there is a lack of evidence-based medicine to confirm its application values.OBJECTIVE:To compare the efficacy of 3D printing-assisted surgery and traditional surgery in the treatment of tibial plateau fractures through a meta-analysis.ME=THODS:MEDLINE,Cochrane library,Embase,CBM,CNKI and WanFang databases were searched by computer and the relevant literatures were retrieved manually,to collect the controlled trials concerning the efficacy of 3D printing-assisted surgery versus traditional surgery for tibial plateau fractures.Methodology quality of the trials was assessed critically and relative data were extracted,followed by analysis on Stata 11.0 (Stata Corporation,College Station,TX) software.RESULTS AND CONCLUSION:(1) Seven controlled trials involving 362 patients were included.(2) Meta-analysis results showed that the 3D printing-assisted surgery had shorter operation time (SMD=-2.411,95％C/=-2.718-2.104,P=-0.00) and less intraoperative blood loss (SMD=-1.579,95％C/=-1.842--1.316,P=-0.00) than those in the traditional surgery.The excellent and good rate in Rasmussen and Hospital for Special Surgery knee scores showed no significant differences between two growps (P ＞ 0.05).(3) To conclude,compared with the traditional surgery,the 3D printing-assisted surgery can significantly shorten the operation time and reduce the intraoperative blood loss in the treatment of tibial plateau fractures.

Objective: To investigate epidemiological characteristics of geriatric hip fractures between 2010 and 2011 in Hebei province. Methods: The digital radiography image data and basic information of patients above 60 years old with hip fractures (femoral neck fracture, femoral intertrochanteric fracture, and femoral head fracture) in 5 hospitals of Hebei province between January 2010 and December 2011 were analyzed retrospectively. All the data including patients' gender, age, and AO types were abstracted and analyzed to investigate the epidemiologic characteristics of geriatric hip fractures in Hebei province. Results: A total of 4 207 hip fracture patients above 60 years old were included, accounting for 59.61% of all patients with hip fractures and 26.24% of all fractures patients over 60 years old in the same period. There were 1 703 (40.48%) males and 2 504 (59.52%) females (M∶F=1∶1.47). The patients ranged in age from 61 to 99 years, with an average of 75.4 years; the majority of patients aged 70-79 years (43.97%) and the minority of the patients aged 90-99 years (2.02%); women of all ages were more than men, but the difference was not significant ( P>0.05). According to AO classification, there were 2 118 cases (50.34%) of type 31-A, 2 004 case (47.63%) of type 31-B, and 85 cases (2.02%) of type 31-C. Except for the type 31-A1, 31-A3, and 31-C1 of 60-69 age group, and the type 31-A3 of 80-89 age groups, women were significantly more than men. Conclusion: There are more women than men in hip fractures in Hebei province, and 70-79 age group is the high-risk age group of geriatric hip fractures. Among them, intertrochanteric comminuted fractures are common types.

Objective To compare and analyze the epidemiological features of Colles fractures between Eastern and Western China from 2010 to 2011.Methods The data of patients with Colles fracture treated from January 2010 to December 2011 in 63 hospitals in Eastern and Western China were analyzed retrospectively.The patients from the 35 hospitals in Eastern China were defined as group A and those from the 28 hospitals in Western China as group B.The 2 groups were analyzed and compared in terms of gender,age and laterality.Results A total of 9,255 Colles fractures were collected.The total male/female ratio was 0.82:1.Their ages ranged from 1 to 110 years,with a median age of 51 years.The Colles fractures predominated in an age range from 51 to 60 years.There were 5,006 left sides and 4,249 right sides.There were 5,639 Colles fractures in group A,accounted for 2.55％ of the total body fractures and 22.09％ of the distal ultra-radius fractures.There were 3,616 Colles fractures in group B,accounted for 3.98％ of the total body fractures and 37.55％ of the distal ultra-radius fractures.The male/female ratio was 0.72:1 in group A and 0.99:1 in group B.The median age was 54 years (from 1 to 110 years) for group A and 45 years (from 1 to 99 years) for group B.There were significant differences between the 2 groups in all the above items (P ＜0.05).The largest proportion of age group was from 51 to 60 years and the smallest proportion of age group was ≥81 years for both groups.The proportions of age groups from 1 to 10 years,from 51 to 60 years,from 61 to 70 years,from 71 to 80 years and ≥81 years in group A were larger than in group B while those from 11 to 20 years,from 21 to 30 years,from 31 to 40 years and from 41 to 50 years in group A were smaller than in group B.There were significant differences between the 2 groups in all the proportions of age group (P ＜0.05).The Colles fractures predominated on the left side in both groups,showing no significant difference between the 2 groups (P ＞ 0.05).Conclusions The Colles fractures from 2010 to 2011 predominated in the elderly and female patients in China.The proportions of Colles fractures in all body fractures and distal ultra-radius fractures in Eastern China were lower than those in Western China.There were significant differences in gender and age proportions between the 2 areas.Eastern China had a larger proportion of female patients and a higher median age than Western China.

Objective To compare and analyze the epidemiological features of adult patients with scapular fracture between eastern and western areas in China from 2010 to 2011. Methods The data of adult patients with scapular fracture who had been treated from January 2010 to December 2011 in 63 hospitals in the eastern and western areas in China were collected through the PACS system and case reports checking system. The data from the eastern 35 hospitals were classified as group A and those from the 28 western hospitals as group B. The analytic items included gender, age and AO classification. Results A total of 2, 063 cases were collected. The median age was 44 years ( interquartile range, from 33 to 56 years ) and gender ratio 3. 50:1 in Group A of 1, 376 cases; the median age was 41 years ( interquartile range, from 31 to 51 years ) and gender ratio 3. 09:1 in Group B of 687 cases. There was a significant difference between the 2 groups in median age ( Z= -3. 798, P=0. 000 ) . There was no significant difference between the 2 groups in gender ratio or constituent ratio of fracture peak age ( P > 0. 05 ) . The proportions of patients from 16 to 20 and from 31 to 40 years old in group A were significantly lower than in group B ( P <0. 05 ) . The proportion of middle-aged patients was significantly higher and that of young patients significantly lower in group A than in group B. The proportion of AO type 14-A fractures in group A ( 66. 49％) was significantly higher than in group B ( 55. 60％) while the proportion of AO type 14-C fractures was significantly lower ( 21. 37％) in group A than in group B ( 29. 55％) . Conclusions Most scapular fractures occurred in male patients. The proportion of young patients in the eastern area was lower than in the western area, but the proportion of middle-aged patients was higher in the eastern area than in the western area. The proportion of AO type 14-A fractures in the eastern area was significantly higher than in the western area while the proportion of AO type 14-C fractures in the eastern area significantly lower than in the western area.

Objective:To evaluate the reliability of cardiac late iodine enhancement dual-energy CT (LIE-DECT) multiparameter post-processing technique for evaluating the presence, location, and extent of cardiac scars in patients with heart failure (HF), using cardiac MR (CMR) late gadolinium enhancement (LGE) as a reference standard.Methods:Thirty-nine HF patients who underwent cardiac LIE-DECT and LGE-CMR examinations in the Second Affiliated Hospital of Nantong University from November 2019 to November 2021 were prospectively collected, all enrolled HF patients underwent LIE-DECT post-processing to reconstruct monoenergetic plus (Mono+) map (40 keV), iodine map and Rho/Z map, to evaluate the enhancement degree, location and extent of left ventricular myocardial LIE on the left ventricular short-axis map, respectively, and compared with LGE-CMR. Cohen′s Kappa test was used to assess the intra-and inter-observer consistency of LIE by DECT multiparameter technique and the consistency of LIE presence and location by DECT multiparameter technique and by CMR. The diagnostic efficacy of DECT multiparameter technique in diagnosing myocardial scar was calculated.Results:Of the 39 patients included, 32 patients were detected by CMR with LGE in 147 segments, including 37 subendocardial patterns, 19 transmural patterns, 74 mid-wall patterns, and 17 epicardial patterns. The intra-observer consistency Kappa values of 40 keV Mono+map, iodine map and Rho/Z map were 0.878, 0.930 and 0.835 ( P all<0.001), respectively. The inter-observer consistency Kappa values were 0.838, 0.892 and 0.808 ( P all<0.001), respectively. The LIE of 40 keV Mono+map, iodine map and Rho/Z map were in good agreement with CMR, Kappa values were 0.903, 0.883 and 0.810 ( P all<0.001), respectively. For the per-patient analysis, the accuracies of 40 keV Mono+map, iodine map and Rho/Z map were 92.3% (36/39), 92.3% (36/39) and 82.1% (32/39), respectively. For the segment-based analysis, the accuracies of 40 keV Mono+map, iodine map and Rho/Z map accuracy were 96.1% (492/512), 95.3% (488/512) and 92.6% (474/512), respectively. In Bland-Altman analysis, the consistency bias between scar extent measured by 40 keV Mono+map, iodine map, Rho/Z map and that measured by LGE-CMR were -2.03%, -2.21%, -2.65%, and the 95% limit of agreement were -12.20%-8.14%, -12.69%-8.28% and -14.85%-9.58%, respectively. Conclusion:LIE-DECT multiparameter technique can detect myocardial scar in HF patients well, which is consistent with LGE-CMR.
