Objective: To evaluate the effect of open reduction and internal fixation on radial head fracture and assess the post-operative function. Methods: This prospective observational study was conducted from June 2016 to July 2017 at Liaquat National Hospital and Medical College, Karachi. Altogether, 28 patients with radial head and neck fractures were enrolled in our study. These patients were admitted to the hospital and their fractures were fixed with open reduction and internal fixation. Baseline information of the patients was collected, and patient-rated elbow evaluation scores were calculated. Results: Out of the 28 patients, 21 were male and 7 were female. Besides, 16 fractures were on the right side and 12 were on the left side and 17 involving the dominant hands. In addition, 8 patients had Mason type Ⅱ fracture and 20 had Mason type Ⅲ fracture. The mean age of patients was (31.0 ± 8.0) years, and the mean follow-up is (1.2 ± 0.5) years. The mean average patient-rated elbow evaluation scores were (27.64 ± 1.60) at 1-year follow-up. Conclusions:The majority of the patients who had radial head fractures and treated by open reduction and internal fixation have attained an excellent range of motion postoperatively.

Internal fixation and unicompartmental knee arthroplasty for an elderly patient with patellar fracture and anteromedial osteoarthritis:A case report

BACKGROUND Open reduction and internal fixation(ORIF)is the traditional surgical treatment for patellar fractures,and unicompartmental knee arthroplasty(UKA),especially Oxford UKA,has been increasingly used in patients with medial knee osteoarthritis(OA).However,the process of choosing treatment for patients with both patellar fractures and anteromedial knee OA remains unclear.We present the case of a patient with a patellar fracture and anteromedial OA.CASE SUMMARY We present the case of a 72-year-old woman with a history of bilateral medial compartment OA of the knees and a right Oxford UKA.She also experienced a recent left patellar fracture.ORIF and Oxford UKA were performed in a single stage.The patient showed excellent postoperative clinical results.CONCLUSION ORIF and Oxford UKA can be performed simultaneously for patients with patellar fracture and anteromedial OA on the same knee.

Triple-functional bone adhesive with enhanced internal fixation,bacteriostasis and osteoinductive properties for open fracture repair

At present,effective fixation and anti-infection implant materials represent the mainstay for the treatment of open fractures.However,external fixation can cause nail tract infections and is ineffective for fixing small fracture fragments.Moreover,closed reduction and internal fixation during the early stage of injury can lead to potential bone infection,conducive to bone nonunion and delayed healing.Herein,we designed a bone adhesive with anti-infection,osteogenic and bone adhesion fixation properties to promote reduction and fixation of open fractures and subsequent soft tissue repair.It was prepared by the reaction of gelatin(Gel)and oxidized starch(OS)with vancomycin(VAN)-loaded mesoporous bioactive glass nanoparticles(MBGNs)covalently cross-linked with Schiff bases.Characterization and adhesion experiments were conducted to validate the successful preparation of the Gel-OS/VAN@MBGNs(GOVM-gel)adhesive.Meanwhile,in vitro cell experiments demonstrated its good antibacterial effects with the ability to stimulate bone marrow mesenchymal stem cell(BMSCs)proliferation,upregulate the expression of alkaline phosphatase(ALP)and osteogenic proteins(RunX2 and OPN)and enhance the deposition of calcium nodules.Additionally,we established a rat skull fracture model and a subcutaneous infection model.The histological analysis showed that bone adhesive enhanced osteogenesis,and in vivo experiments demonstrated that the number of inflammatory cells and bacteria was significantly reduced.Overall,the adhesive could promote early reduction of fractures and antibacterial and osteogenic effects,providing the foothold for treatment of this patient population.

Clinical effect of distal radius fracture treated with open reduction and internal plate fixation

Background For some specific comminuted unstable intra-articular fracture,the plaster cast can not maintain the alignment of the articular surface effectively.The aim of this study was to evaluate the clinical effects of distal radius fracture treated with open reduction and internal plate fixation retrospectively.Methods From January 2002 to March 2010,539 cases of distal radius fracture were treated with open reduction and internal fixation,including 184 males and 355 females aging 21-72 years （mean 57 years）.Fractures were caused by falling to the ground in 459 cases,by traffic accident in 62 cases and by athletic injuries in 18 cases.Of 539 cases,there were 523 cases of closed fracture and 16 cases of open fracture.According to Arbeitsgemeinschaft fur Osteosynthesefragen （AO） standards of classification,there were 14 cases of A2 type,22 of A3 type,18 of B1 type,24 of B2 type,62 of B3 type,91 of C1 type,162 of C2 type and 146 of C3 type.The time from injury to operation was 1-16 days （mean 5 days）.All patitents received open reduction and internal plate screw fixation.Forty-seven patients with bone defect were given 6-15 g autologous ilium and 75 cases were given 5 ml calcium sulphate artificial aggregate after reduction.Results All incisions healed by first intention after operation.Patients were followed up for 15 to 32 months postoperatively （mean 22 months）.The fractures healed within 10-18 weeks after operation （mean 12 weeks）.During the last follow-up,the mean palmar tilt was （7.0±0.9）° and the mean ulnar variance was （21.0±4.2）°,showing significant difference when compared with preoperation （（-5.0±1.2）° and （8.0±3.8）°）.The radial heights were not abbreviated.According to Gartland and Werley assessment system,the results were excellent in 314 cases,good in 163 cases,fair in 46 cases,and poor in 16 cases 12 weeks after operation,the excellent and good rate was 88.5%.Conclusions The clinical effect of distal radius fracture treated with open reduction and internal plate fixation was relatively satisfactory.Meticulous operation procedure and individual rehabilitation strategy contribute to the wrist joint functional recovery.

Efficacy of open reduction and internal fixation with a miniplate and hollow screw in the treatment of Lisfranc injury

Purpose： To investigate efficacy of open reduction and internal fixation with the miniplate and hollow screw in the treatment of Lisfranc injury. Methods： Ten cases of Lisfranc injury treated by open reduction, miniplate and hollow screw in our hospital were retrospectively analyzed. There were 6 males and 4 females with age ranging from 25 to 45 years （mean 32 years）. Among them, one case was classified as Type A, six Type B and three Type C. Injury mechanism included road traffic accidents （3 cases）, fall from height （5 cases） and hit by heavy object （2 cases）. All injuries were closed without cerebral trauma or other complicated injuries. The time interval between injury and operation was 6-10 days （average 6.6 days）. Postoperatively, the foot function was assessed using Visual Analogue Scales （VAS） and American Orthopaedic Foot and Ankle Society （AOFAS） Scales. Healing time and complications were observed. Results： All patients were followed up for 18-24 months （average 20 months）. Anatomic reduction was achieved in all patients on images. There was statistical significance between preoperative score （Z89 ± 0.34） and score at postoperative 8 weeks （0.67 ± 0.13）. According to the AOFAS score, 5 cases were defined as excellent, 3 cases as good and 2 cases as fair. During follow-up, there was no wound infection or complications except for osteoarthritis in 2 cases. Healing time ranged from 3 to 6 months with an average of 3.6 months. Conclusion： Anatomical reduction of Lisfranc injury can be achieved by open reduction and internal fixation with the miniplate and hollow screw. Normal structure of Lisfranc joint is regained to a great extent; injured ligaments were also repaired. Therefore, this method offers excellent curative effect and can avoid postoperative complications and improve the patients＇ quality of life.

Use of gentamicin-loaded collagen sponge in internal fixation of open fractures

Objective： To assess the outcome of immediate plate osteosynthesis via application of antibiotic impregnated collagen fleeces （gentamicin-collagen and an- tibiotic sponge） which gradually release antibiotic locally in the surgical treatment of open fractures presented to us 6 hours after injury. Methods： All cases were treated in our tertiary level trauma center and teaching hospital including 35 patients with open fractures who were treated by immediate open reduction and plate fixation from January 2008 to August 2010. Among them, 31 patients were available for adequate follow-up and assessment. All fractures were treated by irri- gation and debridement, immediate open reduction and plate fixation along with placement of antibiotic-releasing collagen fleeces around the plate just before closure of wound. Pa- tients were assessed to determine postoperative infection, delayed union or nonunion and development of other post- operative complications. It was hypothesized that immedi- ate plate osteosynthesis after thorough debridement and local antibiotics would give safe and acceptable clinical results in treatment of open fractures. Results： The 31 patients with adequate final follow-up were assessed at a mean time of 40 weeks （15-160 weeks）.Most fractures united primarily in an acceptable time period according to area of involvement. Local wound complica- tions （superficial infection and skin loss） were found in 3 patients （9.67%）. Deep infection was noted in 2 patients （6.45%）. None of these patients needed implant removal and both fractures united in due time. Delayed union was noted in 5 patients （16.13%）. No patient progressed to non- union or implant failure in long term follow-up. Excessive scarring was developed in 2 patients （6.45%）. Conclusions： Immediate plate osteosynthesis after adequate debridement and placement of collagen film eluting antibiotics locally produces excellent results regarding bone union and absence of deep infections and is a safe technique in the management of open bone injuries. These sponges can be used easily with any form of internal fixa- tion and there is no need of second surgery for the removal of these antibiotic carriers since they are bioabsorbable. Local antibiotic-impregnated collagen sponges along with systemic antibiotics for 3 to 5 days offer promising results in open fracture management.

Three-dimensional printing combined with open reduction and internal fixation versus open reduction and internal fixation in the treatment of acetabular fractures:A systematic review and meta-analysis

Purpose:This meta-analysis compared the clinical outcome of three-dimensional(3D)printing combined with open reduction and internal fixation(ORIF)to traditional ORIF in the treatment of acetabular fractures.Methods:We searched the Cochrane Library,PubMed,Embase,VIP database,CNKI,and Wanfang data-base with keywords"acetabular fracture","3D printing","three-dimensional printing","open reduction and internal fixation","Acetabulum","Acetabula"from January 2000 to March 2020.Two reviewers independently selected articles,extracted data,assessed the quality evidence and risk bias of included trials using the Cochrane Collaboration’s tools and/or Newcastle-Ottawa scale.When the two analysts had different opinions,they would ask the third analyst for opinion.Randomized controlled trials or retrospective comparative studies of 3D printing combined with ORIF(3D printing group)versus traditional ORIF(conventional group)in the treatment of acetabular fractures were selected.The data of operation time,intraoperative blood loss,intraoperative fluoroscopy times,incidence of complications,excellent and good rate of Matta score for reduction,and excellent and good rate of hip function score were extracted.Stata14.0 statistical software was used for data analysis.Results:Altogether 9 articles were selected,including 5 randomized controlled trials and 4 retrospective studies.A total of 467 patients were analyzed,250 in the conventional group,and 217 in the 3D printing group.The operation time in the 3D printing group was less than that in the conventional group and the difference was statistically significant(standardized mean difference(SMD)=-1.19,95%CI:-1.55 to-0.82,p<0.05).The intraoperative bleeding volume of the 3D printing group was significantly lower than that of the conventional group(SMD=-1.08,95%CI:-1.65 to-0.51,p<0.05).The fluoroscopy times were less in the 3D printing group than in the conventional group and the difference was statistically significant(SMD=-1.64,95%CI:-2.35 to-0.93,p<0.05).The total incidence of complications in the 3D printing group was significantly lower than that in the conventional group(OR=0.43,95%CI:0.24-0.79,p<0.05).There was no significant difference in the excellent and good rate of Matta score for reduction between the two groups(OR=0.60,95%CI:0.34-1.06,p>0.05).There was no significant difference in the excellent and good rate of hip function score at the end of postoperative follow-up between the two groups(OR=0.84,95%CI:0.46-1.56,p>0.05),but the follow-up time varies from 6 months to 40 months.Conclusion:Compared with traditional ORIF,3D printing combined with ORIF has certain advantages in terms that 3D printing not only helps surgeons to understand acetabular fractures more intuitively,but also effectively reduces operation time,intraoperative blood loss,intraoperative fluoroscopy times,and postoperative complications.However,there were no significant differences in the excellent and good rate of Matta score for reduction and the excellent and good rate of hip function score at the end of follow-up.

目的 分析踝关节骨折切开复位内固定(ORIF)术后感染发生情况及其影响因素。方法 选取2021年2月至2023年1月首都医科大学附属北京积水潭医院收治的踝关节骨折患者179例,根据术后30 d内是否发生感染将患者分为感染组(21例)和非感染组(179例)。比较两组一般资料,采用多因素logistic回归分析确定术后感染的影响因素。结果 179例患者中共21例(11.73%)发生感染,均为手术部位感染(SSI)。感染组糖尿病、开放性骨折、ASA分级Ⅲ级、白细胞计数异常、白蛋白异常的占比高于非感染组,骨折至手术时间长于非感染组,差异有统计学意义(P<0.05)。多因素logistic回归分析显示,糖尿病(OR=2.121,95%CI:1.325~3.395)、骨折类型(OR=1.859,95%CI:1.206~2.866)、骨折至手术时间(OR=1.604,95%CI:1.138~2.261)、白蛋白水平(OR=1.455,95%CI:1.078~1.964)是踝关节骨折ORIF术后SSI的影响因素(P<0.05)。结论 伴糖尿病、开放性骨折、ASA分级Ⅲ级及白细胞计数与白蛋白存在异常的踝关节骨折患者ORIF术后更容易发生手术部位感染,临床应重视并积极予以针对性干预。
