ABSTRACT

Objective:To explore the influence of selective fetoscopic laser occlusion of chorioangiopagous vessels (FLOC) versus Solomon surgery in the management of twin-to-twin transfusion syndrome (TTTS) on procedure-related complications, fetal survival rate, and residual anastomoses.Methods:A total of 59 pregnant women with TTTS who underwent FLOC in the Third Affiliated Hospital of Zhengzhou University from May 2018 to March 2020 were retrospectively enrolled and divided into Solomon ( n=33) and selective FLOC groups ( n=26) based on the FLOC operation method. Placentae of 25 pregnant women (15 in the Solomon group, 10 in the selective FLOC group) with both survival twins were perfused to observe the type and diameter of the residual anastomoses. Fetal survival rate, procedure-related complications, and the type and diameter of residual anastomoses were analyzed and compared between the two groups using two independent samples t-test, Mann-Whitney U test, χ2 test and Fisher's exact test. Results:(1) The operating time of Solomon was shorter than that of selective FLOC [74 min (60-90 min) vs 95 min (81-123 min), Z=2.906, P=0.004]. But no statistically significant differences in the gestational week at operation, time of pregnancy end, and the interval between operation and pregnancy end was observed between the two groups (all P>0.05). (2) There was no statistically significant difference in the survival rate of both twins, one fetus, at least one fetus, and the incidence of postoperative twin anemia-polycythemia sequence (TAPS) and recurrent TTTS in the Solomon group and selective FLOC group [64%(21/33) vs 50%(13/26), χ2=1.107; 15%(5/33) vs 35%(9/26), χ2=3.044; 79%(26/33) vs 85%(22/26), χ2=0.326; 3%(1/33) vs 12%(3/26), χ2=1.368; 0% (0/33) vs 4%(1/26), χ2=1.118; all P>0.05]. (3) There was no statistically significant difference in the number of placentae with residual anastomoses or the number of artery-to-vein, vein-to-artery, artery-to-artery, and vein-to-vein anastomoses between the two groups (7/15 vs 6/10, 2/8 vs 4/15, 3/8 vs 4/15, 2/8 vs 5/15, 1/8 vs 2/15; Fisher's exact test, all P>0.05), but the diameter of the residual anastomoses in the Solomon group was smaller than that in the selective FLOC group [(0.8±0.3) and (2.2±0.7) mm, t=0.764, P=0.034]. (4) Among the four pregnant women developed TAPS after operation, one patient had two residual artery-to-vein anastomoses in the placenta with diameter of 0.54 mm and 0.43 mm, respectively; one patient had one artery-to-vein anastomosis with a diameter of 0.64 mm; one had one artery-to-artery and one vein-to-vein anastomosis with diameter of 1.56 mm and 1.89 mm, respectively. Conclusions:Compared with selective FLOC, Solomon surgery can reduce the vessel diameter of residual anastomoses in women with TTTS, but does not reduce postoperative complications, nor improve the pregnancy outcomes.

ABSTRACT

Objective:To summarize the clinical characteristics, diagnosis and treatment of caspase recruitment domain-containing protein 9 (CARD9) gene deficiency associated invasive candidiasis, and report a novel mutation in CARD9 gene.Methods:The clinical characteristics, laboratory tests, treatment and the outcome of follow-up in a boy with invasive candidiasis were described. The boy′s main clinical manifestations were central nervous system infection and retroperitoneal mass. Whole-exome sequencing was performed and Sanger sequencing was verified to identify the CARD9 gene mutations in the patient and his parents. A literature search for “CARD9”and “invasive candidiasis”was conducted in PubMed, Wanfang and CNKI databases from their establishment to May 2020.Results:A 10-year-old boy suffered onset symptom of chronic diarrhea, which lasted for two months. The symptom was followed by progressive neurological symptoms such as headache, vomiting, seizures and disorder of consciousness. His unusual medical history was absent. Candida albicans were cultured several times in cerebrospinal fluid and blood, and yeast-like fungi were found in the stool high power field of vision. Cerebral magnetic resonance imaging indicated obstructive hydrocephalus and abdominal CT scan showed retroperitoneal mass and thickening of the intestinal wall. The whole-exome sequencing analyses of blood samples from the boy and his parents were performed. The results showed that there was a homozygous mutation of c.952-12_956delinsAG in the CARD9 gene, which was an unreported pathogenic mutation. This was confirmed by Sanger sequencing. There was no significant relief from intravenous combined antifungal medications. After lateral ventricular drainage surgery and injection of amphotericin B into the lateral ventricle, improvement of clinical symptoms and cerebral spinal fluid abnormalities was observed after nine weeks, and the retroperitoneal mass shrank. At follow-up after four-month oral combined antifungal medications, the child had no complaint except fatigue. However, cerebral spinal fluid analysis showed increased protein level and decreased glucose. Persistent hydrocephalus and periventricular white matter abnormal signals were revealed on the brain magnetic resonance imaging and the smaller retroperitoneal mass than before on the abdominal CT scan. In addition to this case, totally 21 cases with CARD9 gene deficiency associated invasive candidiasis have been reported worldwide, most of which featured central nervous system infections.Conclusions:CARD9 gene deficiency is an autosomal recessive primary immunodeficiency that confers human susceptibility to fungal disease. The associated invasive candidiasis often affects the central nervous system and makes the patient severely ill. Adequate systemic antifungal therapies should be given, and patients with hydrocephalus need surgical treatment. A novel mutation is reported that expands the variant diversity of CARD9 gene. For patients with unexplained invasive candidiasis, including those without a history of previous recurrent infection, genetic testing is recommended for primary immunodeficiency including CARD9 gene deficiency.

ABSTRACT

The appropriate sample size estimation is very important in the design of clinical trials. However, insufficient or inappropriate sample size estimation is still a prominent problem in the currently published acupuncture and moxibustion clinical trials. At present, the superiority test, non-inferiority test and equivalence test have been widely used in acupuncture and moxibustion clinical trials. This article focuses on the application, calculation methods and PASS11 software using of these three hypothesis test types. In view of the problems in the estimation of sample size in acupuncture and moxibustion clinical trials, the particularity of sample size estimation in acupuncture and moxibustion is summarized from the aspects of parameter setting, ratio of intervention group and control group, and multi-group comparison, in order to guide acupuncture clinical researchers to correctly estimate sample size when conducting clinical trials.

ABSTRACT

OBJECTIVE@#To explore the genetic basis for a pedigree affected with X-linked recessive mental retardation Claes-Jensen type.@*METHODS@#Genomic DNA was extracted from peripheral blood samples of the patient, his parents (phenotypically normal) and two elder brothers with similar clinical manifestations. Whole exome sequencing was carried out for the proband, and the result was verified by Sanger sequencing.@*RESULTS@#The proband was found to harbor a hemizygous c.1565C>T missense variant in exon 11 of the KDM5C gene. The transition has resulted in replacement of serine by phenylalanine at position 522 (p.Ser522Phe). Sanger sequencing showed that the patient's two elder brothers and mother carried the same variant, which was predicted to be probably damaging by SIFT, PolyPhen2 and Mutation_Taster. The three affected brothers presented with similar clinical phenotypes characterized by mental retardation, speech delay, behavioral problem, self-limited epilepsy responsible to medication, short stature and microcephaly. The mother only had mild cognitive impairment and learning disability. The same variant was not found in their father and was unreported previously.@*CONCLUSION@#The c.1565C>T (p.Ser522Phe) of the KDM5C gene probably underlay the X-linked recessive mental retardation Claes-Jensen type in this pedigree.

ABSTRACT

Objective:To summarize the phenotype of mtDNA8344A>G and to explore the new phenotype.Methods:A family with mtDNA 8344A>G was retrospectively analyzed in the Children′s Hospital Affiliated to the Capital Institute of Pediatrics in April 2019. The clinical data of the proband and his mother were collected and summarized.Results:A four-year-old boy presented with rapidly progressing central respiratory failure and continuous mechanical ventilation, whose serum lactate levels fluctuated between 4.5 to 8.3 mmol/L. Linear abnormality signals from dorsal medulla to the first and second cervical spine were displayed on cranial magnetic resonance imaging. Ragged red fiber and ragged broken blue fibers, cytochrome C oxidase negative muscle fibers and enhanced vascular succinate dehydrogenase reaction were seen in muscle biopsy, accorded with the pathological characteristics of mitochondrial myopathy. The activity detection of respiratory chain enzyme complex in muscle tissues showed decreased activity of mitochondrial respiratory chain enzyme complex Ⅰ and complex Ⅳ. mtDNA 8344A>G mutation was detected in his peripheral blood lymphocyte and urine exfoliated epithelial cells. The proportion of mutations in his blood lymphocytes was 77.29%, and the proportion of mutations in his urothelial epithelial cells was 90.13%. His mother was 30 years old, thin in stature without obvious clinical symptoms and signs. The mutant mtDNA 8344A>G was also detected in her peripheral blood and urine. The mutant rate in her blood and urine was 77.29% and 90.13% respectively.Conclusions:A case of rapidly progressive central respiratory failure in children and his family are reported. Genetic testing showed mtDNA8344A>G mutation, and both muscle biopsy pathology and muscle tissue respiratory chain enzyme complex activity test results supported mitochondrial disease. By this case, the phenotype spectrum of the gene was expanded.

ABSTRACT

Objective@#To investigate the effects of acetabular coverage on the initial stability of the cup during total hip arthroplasty in developmental dysplasia of hip.@*Methods@#There were 50 fourth-generation synthetic hemi-pelvises. The different cup coverage rate (100% group, 70% group, 60% group, 50% group, 40% group) was created in pelvis with 10 specimens per group. The synthetic hemi-pelvis was fixed rigidly to a customized fixture which was placed on the testing table of the material testing machine. Pull-out and torque test were conducted by computer-control in torsion testing machine.@*Results@#In the acetabular cup pull-out test, the average pull-out force for mode of failure in 100%, 70%, 60%, 50%, and 40% group was 1 560.4±438.7, 1 467.2±349.8, 1 137.8±427.4, 737.4±134.8, 506.6±119.0 N, respectively. The pull-out force was reduced gradually. The pull-out force in 100% group was significantly higher than that in 50% (P=0.004) and 40% (P=0.001) group. The pull-out force in 70% group was significantly higher than that in 50% group (P=0.002) and 40% group (P=0.000). The force in 40% group was significantly lower than that in 60% group (P=0.013) and 50% group (P=0.021). In the acetabular cup torque test, the average torque for mode of failure in 100%, 70%, 60%, 50%, and 40% group was 28.0±3.7, 17.0±2.2, 9.4±1.1, 7.6±1.1, 6.4±1.1 N·m, respectively. The torque was reduced gradually. The torque in 100% group was significantly higher than that in other groups (P<0.05). There was no significant difference between 50% and 40% group (P>0.05). The torque in other groups were similar (P>0.05).@*Conclusion@#The present biomechanical study showed that different acetabular cup coverage rate affected the initial stability of the cup. The highest initial stability was observed in the cup with a 100% of cup coverage rate. The cup could not obtain 100% coverage when with acetabular rim defect. We should try our best to make the cup coverage reach to 70%. The 70% coverage rate has sufficient initial stability to meet daily activities without increasing the cup loosening rate.

ABSTRACT

To evaluate the efficacy and safety of huperzine in treating patients with mild cognitive impairment. The randomized controlled trials(RCT) were retrieved from EMbase, Cochrane Library, PubMed, CNKI, Wanfang and VIP. The methodology quality of the included studies was evaluated, and a Meta-analysis was performed using RevMan 5.3 software. A total of nine RCTs were included. The Meta-analysis results showed that compared with placebo, Huperzine significantly increased the scores of memory quotient(MQ) and mini-mental state examination(MMSE). However, there was no statistical difference between oral tablet and capsule. Compared with placebo, huperzine A was superior in the scores of MQ and MMSE. Huperzine is safe with mild side effects. Due to the low quality of original studies, more high-quality studies are needed to verify its efficacy.

ABSTRACT

Objective To compare the clinical efficacy and biomechanical property between unilateral fixator (UF) and Taylor fixator (TF) for treating Gustilo Ⅱ tibiofibula fracture. Methods In this retrospective study ,86 patients with open tibiofibula fracture admitted from January 2012 to August 2015 were divided into an UF group (n= 49) or a TF group (n= 37) according to fixing method ,and their clinical efficacy and biomechanical property were compared. Providing the finite element model was fully proved effective ,the axial stiffness ,bending stiffness and torsional stiffness of UF and TF were tested by this model.Additionally ,the torsional stiffness was measured at every 10° revolving around the model. Results The operation time was shorter in UF group (43.2 ± 11.7) min than in TF group (63.6 ± 9.8) min (P=0.027) ,and blood loss was less in the UF group (32.1 ± 13.8) ml than in TF group (57.6 ± 23.1) ml (P<0.001).All the patients were followed up for 8-31 months (mean:13.8 months). The healing time was shorter in the UF group (4.6 ± 1.7) months thanintheTFgroup(5.7 ±2.1)months(P=0.039).Thecomplicationrateswere4.5% (9/201)in the UF group ,which was significantly less than that in the TF group (12.0% ,14/117) (P<0.05) .For biomechanical property ,the axial ,bending and torsional stiffnesses were higher in the UF group [(341.47 N/m ,80 Nm/deg ,and (210-430) N/m ,respectively]than in the TF group[226.83 N/m ,72 Nm/deg ,and (242-287 ) N/m ,respectively ]. Conclusions In the treatment of open tibiofibula fracture ,UF is easier to operate and has better agreement with the biomechanical property and better ability to resist a rotation and a compression ,which is obviously superior to TF.Besides ,UF is better than TF for fracture recovery.

ABSTRACT

Traditional Chinese medicine (TCM) injections are very useful in the treatment of acute and severe diseases due to their rapid onset. While, adverse drug reactions (ADRs) of TCM injections is an important problem, how to quickly detect ADRs signal of TCM injections is a key and difficult issue to make sure the safely application of TCM injections.Prescription sequence symmetry analysis (PSSA) is an effective surveillance tool for drug associated ADRs, through examining the distribution of marker drugs (potentially used for managing ADRs), before and after initiation of index drugs, PSSA can evaluate the causal association of index drugs and ADRs. PSSA can quickly detect ADRs signal based on medical electronic databases or prescription databases, which is suitable for the rapid emergence of ADRs for TCM injections. We described the basic principle and worldwide researches of PSSA, then we introduced the research methods when using PSSA to analyze the three aspects of ADRs for TCM injections. At present, when we use PSSA to detect ADRs signals in electronic prescription databases in China, we still need to think about the number of patients, structure and combination of data. With the development of medical electronic databases in China, PSSA can be more used to detect ADRs signal.

ABSTRACT

The metastasis in which the cancer cells degrade the extracellular matrix (ECM) and invade to the sur-rounding and far tissues of the body is the leading cause of mortality in cancer patients. With a lot of advancement in the field, yet the biological cause of metastasis are poorly understood. The microfluidic system provides advanced technology to reconstruct a variety of in vivo-like environment for studying the interactions between tumor cells (TCs) and endothelial cells (ECs). This review gives a brief account of both two-dimensional models and three-dimensional microfluidic systems for the analysis of TCs-ECs co-culture as well as their applications to anti-cancer drug screening. Furthermore, the advanced methods for analyzing cell-to-cell interactions at single-cell level were also discussed.

ABSTRACT

BACKGROUND: Basal metabolic rate (BMR) is an important indicator of human energy metabolism, and low BMR leads to the dysfunction of liver and kidney. Low BMR is usually found in patients with hip fractures, but there is a lack of study on the relationship between mortality of hip fracture and low BMR. OBJECTIVE: To investigate the effect of low BMR on the 1-year mortality in older adults with hip fractures. METHODS: Totally 507 patients with hip fractures aged more than 60 years from January 2014 to March 2016 were included in this retrospective study. Age, sex, surgery or not, surgical pathway, duration from injury to surgery, hospitalized pulmonary infection, number and kind of comorbidities, and 1-year mortality were recorded. BMR on admission was recorded, and multiple Logistic regression analysis was applied. RESULTS AND CONCLUSION: All patients were followed up for 13-15 months, and the 1-year mortality was 13.41% (68/507). The mortality in the low BMR group was significantly higher than that in the non-low BMR group (P < 0.05). Logistic regression analysis showed that older age, conventional treatment, number of combined medical diseases, hospitalized pulmonary infection, and low BMR are risk factors for 1-year mortality in older adults with hip fracture. These results imply that low BMR is strongly associated with 1-year mortality in older adults with hip fracture. BMR can reflect the nutritional status, neuroendocrine, cellular and energy metabolism. Thereafter, for older adults with hip fractures and low BMI, nutrition therapy, re-warming, and endocrine therapy may help reduce the trauma-induced mortality.

ABSTRACT

BACKGROUND: Total hip arthroplasty has been widely used in clinical practice, and achieved good clinical efficacy. However, with the yearly increased number of patients receiving primary arthroplasty, the number of revision hip arthroplasty patients has increased. However, hip arthroplasty is one of the most difficult hip surgery, and it is challenging. OBJECTIVE: To review the causes of femoral revision of the hip arthroplasty, the classification of the femoral bone defect, and the type of prosthesis available in the clinical revision, and the clinical effect of the different prosthesis, so as to provide reference for femoral revision. METHODS: CNKI, Web of Science, and PubMed were searched for the literatures published between January 1975 and August 2017 with the key words of "Revision total hip arthroplasty, Femur revision, Cemented femoral revision, Cemenless femoral revision Reoperation, Porous-coated stems, Modular, tapered stem, Wagner SL revision Stem". RESULTS AND CONCLUSION: (1) A total of 1 041 articles were retrieved. After reading the abstract, unrelated and repeated studies were excluded. Finally, 109 studies were included. Of them, there were 106 English studies and 3 Chinese studies. Femoral revision was analyzed and summarized. (2) Femoral revision of the hip is still the future challenges facing the joint surgeon. We continue to strive to overcome the direction. Although the current material science and surgical technology are now rapidly developed, only the analysis of the reasons for the revision of the femoral side, identifying the femoral side bone defect classification, mastering the treatment of different defects and the application of the principle of prosthesis type, making reasonable femoral revision program is the key to success according to the patient's age and activity.

ABSTRACT

Clinical practice guideline on traditional Chinese medicine therapy alone or combined with antibiotics for sepsis is strictly in accordance with the latest diagnostic criteria for sepsis (sepsis-3) for the treatment of septic patients at different stages through syndrome differentiation. At present, the abuse of antibiotics and the prevalence of drug-resistant bacteria are very serious, without effective solutions. Thus, this is the first time to focus on traditional Chinese medicine combined with antibiotics to treat sepsis, in order to minimize the incidence of drug-resistant bacteria. This Guideline tends to systematically analyze the sepsis period, septic shock period as well as different clinical symptoms and traditional Chinese medicine measures for organ dysfunction in the sepsis process. By analyzing and interpreting the Guideline systematically, the clinicians could understand its purpose, significance and core ideas more thoroughly, and grasp the recommended specific interventions as well as their advantages and disadvantages, hoping to better implement the Guideline, provide guidance to clinicians and standardize the treatment of sepsis by traditional Chinese medicine.

ABSTRACT

Objective To assess the mid-or long-term clinical outcomes of the structural bone graft of superolateral acetabulum in total hip arthroplasty (THA) for developmental dysplasia of the hip (DDH).Methods Thirty-three patients with DDH (33 hips) were treated by THA with the structural bone graft of superolateral acetabulum technique between April 2002 and December 2011.There were 28 females and 5 males with the mean age at surgery 54.0±14.5 years (21-76 years).The degree of dislocation was graded preoperatively as Crowe Ⅱ in 12 patients,Crowe Ⅲ in 8 patients,and Crowe Ⅳ in 13 patients.The following outcomes were assessed,Harris hip score (HHS),the leg-length discrepancy,the height and horizontal distance of center of hip rotation,rate of cup coverage,the coverage ratio of bone graft,periprosthetic osteolysis,bone ingrowth,and cup loosening.Results The average follow-up was 9.3±3.3 years (5-15 years).The HHS improved from 40.9±13.7 preoperatively to 93.6±7.8 at the final follow-up (t=21.483,P=0.000).The leg-length discrepancy decreased from 24.2± 17.1 mm pre-operatively to 3.7±3.5 mm at postoperative 3 months (t=6.747,P=0.000).The height and horizontal distance of center of hip rotation decreased from preoperative 45.9±16.0 mm and 42.9±8.7 mm to postoperative 23.8±5.8 mm and 23.6±2.9 mm (t=7.460,P=0.000;t=12.090,P=0.000) at postoperative 3 days,respectively.The cup coverage and coverage ratio of bone graft was 100% and 27.1%±6.9%,respectively.All grafts appeared to be incorporated without evidence of resorption and collapse.The mean time of incorporation was 7.6 ± 2.8 months.The coverage ratio of bone graft >25% have a significantly long time of incorporation than that <25% (9.4±2.3 months versus 6.3±2.4 months,t=5.357,P=0.000).At the final follow-up,all hips showed bone ingrowth fixation of the acetabular cup and stem.Five hips showed osteolysis,two hips in acetabular zone Ⅱ,three hips in femur zone Ⅰ and five hips in femur zone Ⅶ.The main complications were intraoperative femoral fractures (61%) without neurological damage,nonunion and dislocation.Conclusion The structural bone graft of superolateral acetabulum in THA for DDH can achieve satisfactory mid-or long-term outcomes.The superolateral acetabular deficiency can be reconstructed by bone graft.The bone graft coverage less than 25% is conducive to fusion of bone graft and acetabular bone.However,intraoperative femoral fracture is common complication.

ABSTRACT

BACKGROUND: With the rapid development of surgical techniques, unicompartmental knee arthroplasty has become an issue of concern in the treatment of osteoarthritis, which has achieved significant progress inreducing trauma and rapid rehabilitation.OBJECTIVE: To summarize the development history, curative effect of unicompartmental knee arthroplasty, and the research progress of lateral unicompartmental knee arthroplasty aided with computer navigation or robot system, thus providing reference for further study on unicompartmental knee arthroplasty.METHODS: Web of Science, and PubMed databases were searched for the literatures published from January 1955 to April 2017 with the keywords of unicompartmental knee arthroplasty, osteoarthritis, unilateral compartment, lateral knee arthroplasty.RESULTS AND CONCLUSION: A total of 562 articles were retrieved, and finally 75 English literatures were enrolled according to the inclusion and exclusion criteria. With the continuous improvement of unicompartmental knee arthroplasty, it can retain the cruciate ligament and more bone mass. Notably, strict indications and reasonable postoperative functional exercise are essential for obtaining optimal effectiveness. At the same time, the development of computer navigation and robot-assisted technology has opened up a new horizon for the treatment of osteoarthritis,which makes the operation more accurate and minimally invasive. But the application still needs to be studied in depth.

Objective To evaluate the application value of whole exome sequencing (WES) in diagnosis of NDDs (neuro-developmental disorders) children.Metheod WES was used for the diagnosis of 35 unexplained NDD children, which admitted to the outpatient and ward of Children′s hospital affiliated to Capital institute of pediatric from November 2015 to November 2016.These children′s clinical data was collected detailedly.Using bioinformatics software tools combining with patient′s phenotype, the candidate genetic/genomic variants of these patients were identified from WES data.The final pathogenicity of genetic/genomic variants was interpreted according to the guideline of the American College of Medical Genetics and Genomics (ACMG), meanwhile, the variants validation and co-separation analysis in the parents and their family members were performed by Sanger sequencing, real time-PCR and multiplex ligation-dependent probe amplification (MLPA).Results 14 pathogenic single nucleotide variants (SNVs) and three pathogenic copy number variations (CNVs) were detected in the 35 NDD children, the detection rate in this study is 48.6%.Among the 14 pathogenic SNVs, 11 of them are the definite NDD-related genes according to OMIM database (such as CHARGE syndrome, Wiedemann-Steiner syndrome, Cockayne syndrome, etc.), and six of them are de novo (6/11, 54.6%).Three pathogenic CNVs were identified from WES data, including two microduplications and one microdeletion.Meanwhile, a female child carrying a frame shift mutation in MECP2 was found and the germline mosaicism with low-frequency mutation of this site (8.4%) was confirmed by his father's sperm.Conclusions The diagnosis rate of WES in NDDs children is 48.6% in our small-sample study.In addition to pathogenic/likely pathogenic SNVs, CNVs can be detected successfully from WES data, which effectively improved the diagnosis yield in NDDs children.

ABSTRACT

Objective To analyze the epidemiology,mechanisms of injury,type of fracture,clinical and radiological feature of acetabular fractures in patients aged 60 years and older.Methods Retrospectively analyzed the clinical data of patients with acetabular fractures between Janurary 1990 and December 2013 in Orthopaedic Department of the First Affiliated Hospital of Soochow University.According to certain inclusion and exclusion criteria,a total of 637 patients (637 hips) with acetabular fractures were included in the study.The patients were divided into 2 group acetabular fractures in elderly (≥60 years) and acetabular fractures in younger patients (< 60 years).Analysis of mechanism of injury,fracture pattern,the annual incidence of fracture,radiological features,associated injuries.Results 133 patients were ≥60 years and the remaining 504 were < 60 years.We identified a significant increase in the incidence of elderly with acetabular fractures between 1990 and 2013 (6.7% in 1990 vs.40.0% in 2013).The incidence of associated injuries were significant lower in the elderly than younger (27.1% vs.48.8%).The most common mechanism of injury in the elderly was a fall (36.1%),but this accounted for only 0.2% of the younger with fractures.The incidence of anterior wall,anterior column,anterior and posterior hemitransverse were significant higher in the elderly than younger.The incidence of radiological features were significant higher in the elderly than younger,including quadrilateral plate fracture,Gull sign,anterior dislocation of hip,femoral head injury,comminuted posterior wall fracture and posterior wall marginal impaction,except posterior dislocation of hip which was significant lower in the elderly than younger.Conclusion There was an increasing trend of the proportion of elderly in acetabular fractures and the mean age of patients with fractures during the period of study.The older had a different incidence of associated injuries,mechanism of injury,fracture pattern,and radiological features compared with the younger.
