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.

Modified Closed Reduction and Percutaneous Kirschner Wires Internal Fixation for Treatment of Supracondylar Humerus Fractures in Children

Objective Supracondylar humerus fractures are the most frequent fractures of the paediatric elbow.The present study introduced a modified surgical procedure for treatment of supracondylar humerus fractures in children.Methods From February 2015 to August 2019,73 patients with Gartland’s type II and III supracondylar fractures were treated with this modified method.Totally,68 of all patients were followed up for 3–12 months(mean 8.25 months).The evaluation results included fracture nonunion,ulnar nerve injury,pin track infection,carrying angle and elbow joint Flynn score.Results The results showed that bone union was observed in all children,one case had an iatrogenic ulnar nerve injury,and the symptoms were completely relieved in 4 months after removing of the medial-side pin.All children had no cubitus varus deformity and no pin track infection,and the rate of satisfactory results according to Flynn’s criteria score was 100%.Conclusion The modified closed reduction and Kirschner wires internal fixation could effectively reduce the rate of open reduction,the risk of iatrogenic ulnar nerve injury,and the incidence of cubitus varus deformity in treatment of supracondylar humerus fractures in children.

Clinical Analysis of Minimally Invasive Single-segment Reduction and Internal Fixation in Patients with Thoracolumbar Fractures

Objective:To study the clinical effect of minimally invasive single-segment reduction and internal fixation in patients with thoracolumbar fractures.Methods:From June 2013 to June 2014,100 patients with thoracolumbar fractures were selected as the subjects and they were randomly divided into observation group(50 cases)and control group(50 cases).The patients in the observation group were treated with minimally invasive singlesegment reduction and internal fixation.The patients in the control group were treated with short segmental fixation.The clinical effects of the two groups were compared.Results:There was no significant difference in the compression rate and Cobb angle between the two groups before and after operation(P>0.05).For all patients who were followed up for the last time,the Cobb angle was significantly lower in the observation group than in the control group(P<0.05).The social function,affective function and physical pain score of the observation group were significantly better than the control group(P<0.05).The amount of bleeding in the observation group was(250.4±41.0)ml,which was significantly lower than that in the control group(267.5±32.8)ml.The time required for the operation was(90.2±35.4)min,which was significantly lower than that of the control group(104.5±22.6)min(P<0.05).After treatment,the prognosis was 70.00%and the excellent and good rate was 98.00%,which was significantly higher than that of the control group(46.00%)and 78.00%(P<0.05).Conclusion:Thoracolumbar fractures in patients with dilated channel minimally invasive single-segment reduction and internal fixation treatment can effectively repair the patient's vertebral height and Cobb angle and the degree of correction after surgery was significantly better,safer and worthy of clinical recommended use.

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.

Diagnosis,treatment and complications of radial head and neck fractures in the pediatric patient

Radial head and neck fractures represent up to 14%of all pediatric elbow fractures and can be a difficult challenge in the pediatric patient.In up to 39%of proximal radius fractures,there is a concomitant fracture,which can easily be overlooked on the initial standard radiographs.The treatment options for proximal radius fractures in children range from non-surgical treatment,such as immobilization alone and closed reduction followed by immobilization,to more invasive options,including closed reduction with percutaneous pinning and open reduction with internal fixation.The choice of treatment depends on the degree of angulation and displacement of the fracture and the age of the patient;an angulation of less than 30 degrees and translation of less than 50%is generally accepted,whereas a higher degree of displacement is considered an indication for surgical intervention.Fractures with limited displacement and non-surgical treatment generally result in superior outcomes in terms of patient-reported outcome measures,range of motion and complications compared to severely displaced fractures requiring surgical intervention.With proper management,good to excellent results are achieved in most cases,and long-term sequelae are rare.However,severe complications do occur,including radio-ulnar synostosis,osteonecrosis,rotational impairment,and premature physeal closure with a malformation of the radial head as a result,especially after more invasive procedures.Adequate follow-up is therefore warranted.

Percutaneous reduction combined with bone graft in treatment of displaced intra-articular calcaneal fractures

Objective： To introduce the experience and key points of percutaneous reduction combined with bone graft to treat calcaneal fractures. Methods： Percutaneous reduction and internal fixation combined with bone graft was performed from April 2004 to April 2006 on 15 cases （16 sides） with intra-articular calcaneal fractures including 13 males （14 feet） and 2 females （2 feet） ,with average age of 36. 6 years （24-61 years）. All patients underwent radiography including lateral and axial views for calcaneus, oblique view for foot and three-dimensional CT imaging reconstruction. According to Sanders classification, there were 12 feet of type Ⅱ （3 type Ⅱa, 3 type Ⅱb and 8 type Ⅱc） and 2 feet of type Illac. The length of calcaneus was recovered through traction by Steinmann pin which passed through calcaneal tubercle perpendicularly and the posterior facet was elevated until reduction by a curve scissors through an 0.5 cm incision along the primary fracture line of lateral calcaneus. The calcaneus was fixed with different cannulated cancellous screws according to the type of fractures. Then bone graft was injected to fill the defect of calcaneus through lateral incision. Results： All patients were followed up for an average of 18.4 months （ranged, 12 to 34 months）. No complication such as wound infection, screw breakage and calcaneum varus was found postoperatively. The average time for bone healing was 10 weeks. The results were excellent in 12 cases, good in 4 cases according to the American Orthopaedic Foot and Ankle Society （AOFAS） hindfoot score. The rate of excellent and good clinical results was 100%. The mean AOFAS hindfoot score in tongue type group （86.5±4.4） was better than in joint depression type group （81.2±1.7, P〈0.05）. Radiography showed basic restoration of Bohler＇s angle, Gissane＇s angle and calcaneal shape. Conclusion： The combination of percutaneous reduction and injectable bone graft is suitable for surgical treatment of Sanders Ⅱ and Ⅲ type calcaneal fractures, with advantages of simple operation, fewer complications and good clinical results.

Surgical treatment of bipolar segmental clavicle fracture:A case report

BACKGROUND Shoulder injuries caused by trauma are common,including clavicle fractures.Even so,bipolar segmental fracture of the clavicle is extremely rare and seldom reported.Therefore,there is still a controversial issue about how to treat these bipolar segmental clavicle fractures.CASE SUMMARY A 56-year-old security guard arrived at our emergency room after falling on his electric bicycle.There was no loss of consciousness or other pain.He had no numbness in his fingers.X-rays and 3D computed tomography revealed that the patient’s right shoulder had a bipolar segmental clavicle fracture.The surgical procedure included both open reduction and internal fixation.At the 1-year follow-up,he had a full range of motion and minimal discomfort in the injured shoulder.CONCLUSION We provide a rare case of bipolar clavicle facture in the right clavicle.We hold the opinion that such patients would get better clinical and radiological outcomes by early and correct operation.

An Isolated Displaced Fracture of the Coracoid Process Treated with Osteosynthesis—A Case Report and Review of Literature

Coracoid process fractures are relatively rare and few cases have been reported in the orthopedic literature. In this article, we report the case of an active, thirty years old, male patient with isolated, displaced fracture of the coracoid process, associated with a blunt injury to the shoulder, during a motor vehicle accident. We describe the incidence, mechanism of injury, and surgical treatment. Although rare, a high index of suspicion, special radiographic views, can detect an isolated coracoid process. Knowledge of the associated injuries will help the clinician to order further imaging and treat them accordingly. We recommend that a displaced, isolated fracture of the coracoid be treated with open reduction and osteosynthesis, to achieve early use of the extremity, good radiological union and clinical function.

Fragility of statistically significant findings from randomized clinical trials of surgical treatment of humeral shaft fractures:A systematic review

BACKGROUND Despite recent meta-analyses of randomized controlled trials(RCTs),there remains no consensus regarding the preferred surgical treatment for humeral shaft fractures.The fragility index(FI)is an emerging tool used to evaluate the robustness of RCTs by quantifying the number of participants in a study group that would need to switch outcomes in order to reverse the study conclusions.AIM To investigate the fragility index of randomized control trials assessing outcomes of operative fixation in proximal humerus fractures.METHODS We completed a systematic review of RCTs evaluating the surgical treatment of humeral shaft fractures.Inclusion criteria included:articles published in English;patients randomized and allotted in 1:1 ratio to 2 parallel arms;and dichotomous outcome variables.The FI was calculated for total complications,each complication individually,and secondary surgeries using the Fisher exact test,as previously published.RESULTS Fifteen RCTs were included in the analysis comparing open reduction plate osteosynthesis with dynamic compression plate or locking compression plate,intramedullary nail,and minimally invasive plate osteosynthesis.The median FI was 0 for all parameters analyzed.Regarding individual outcomes,the FI was 0 for 81/91(89%)of outcomes.The FI exceeded the number lost to follow up in only 2/91(2%)outcomes.CONCLUSION The FI shows that data from RCTs regarding operative treatment of humeral shaft fractures are fragile and does not demonstrate superiority of any particular surgical technique.

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.

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.

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.

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.
