Open reduction and internal fixation for radial head fractures: A prospective observational study

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.

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.

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.

Atraumatic groin pain secondary to an aneurysmal bone cyst:A case report and literature review

BACKGROUND Bone lesions can present the multi-displinary team with a challenge by way of diagnosis as some lesions share many radiological and histological characteristics.Giant cell tumours of the bone(GCTB)are relatively common,benign bone tumours.Aneurysmal bone cysts(ABC)are less common benign osteolytic lesions that are histologically similar to GCTBs but produce blood filled cavities.Both GCTBs and ABCs are locally aggressive and are typically found on meta-epiphyseal regions of long bones with pelvic tumours being less common.CASE SUMMARY A 17-year old female presented with atraumatic right groin pain and was initially diagnosed with a GCTB on the right superior pubic ramus of the pelvis.The patient was treated successfully with a wide excision,curettage and bone graft and underwent open reduction and internal fixation of the right hemi-pelvis.Following further intra-operative histological investigations,the lesion was diagnosed as an ABC.CONCLUSION This patient has had an uncomplicated post-operative course,has returned to comfortable weight bearing and will be reviewed for minimum 5 yr in the outpatient setting to monitor for reoccurrence.

Comparison of a minimally invasive osteosynthesis technique with conventional open surgery for transverse patellar fractures

Parpose:The study aims to compare the efficacy and safety of a new minimally invasive osteosynthesis technique with those of conventional open surgery for transverse patellar fractures.Methods:It was a retrospective study.Adult patients with closed transverse patellar fracture were included,and with open comminuted patellar fracture were excluded.These patients were divided into minimally invasive osteosynthesis technique(MIOT)group and open reduction and internal fixation(ORIF)group.Surgical time,frequency of intraoperative fluoroscopy,visual analogue scale score,flexion,extension,Lysholm knee score,infection,malreduction,implant migration and implant irritation in two groups were recorded and compared.Statistical analysis was performed by the SPsS software package(version 19).A p<0.05 indicated statistical significance.Results:A total of 55 patients with transverse patellar fractures enrolled in this study,the minimally invasive technique was performed in 27 cases,and open reduction was performed in 28 cases.The surgical time in the ORIF group was shorter than that in the MIOT group(p=0.033).The visual analogue scale scores in the MIOT group were significantly lower than those in the ORIF group only in the first month after surgery(p=0.015).Flexion was restored faster in the MIOT group than that in the ORIF group at one month(p=0.001)and three months(p=0.015).Extension was recovered faster in the MIOT group than that in the ORIF group at one month(p=0.031)and three months(p=0.023).The recorded Lysholm knee scores in the MIOT group were always greater than those in the ORIF group.Complications,such as infection,malreduction,implant migration,and implant irritation,occurred more frequently in the ORIF group.Conclusion:Compared with the ORIF group,the MIOT group reduced postoperative pain and had less complications and better exercise rehabilitation.Although it requires a long operation time,MIOT may be a wise choice for transverse patellar fractures.

Therapeutic effect of two methods on avulsion fracture of tibial insertion of anterior cruciate ligament

BACKGROUND The tibial stop of anterior cruciate ligament(ACL) is fan-shaped and attached to the medial groove in front of the intercondylar spine,which is located between the anterior horn of the medial and lateral meniscus.The incidence of this fracture is low previously reported,which is common in children and adolescents.With the increase of sports injury and traffic injury and the deepening of understanding,it is found that the incidence of the disease is high at present.AIM To explore the difference between open reduction and internal fixation with small incision and high-intensity non-absorbable suture under arthroscopy in the treatment of tibial avulsion fracture of ACL.METHODS Seventy-six patients with tibial avulsion fracture of anterior cruciate ligament diagnosed and treated in Guanyun County People’s Hospital from April 2018 to June 2020 were retrospectively analyzed.According to the surgical methods,they were divided into group A(40 cases) and group B(36 cases).Patients in group A were treated with arthroscopic high-strength non-absorbable suture,and patients in group B were treated with small incision open reduction and internal fixation.The operation time,fracture healing time,knee joint activity and functional score before and after operation,and surgical complications of the two groups were compared.RESULTS The operation time of group A was higher than that of group B,and the difference was statistically significant(P < 0.05);the fracture healing time of group A was compared with that of group B,and the difference was not statistically significant(P > 0.05);The knee joint function activity was compared between two groups before operation,3 mo and 6 mo after operation,and the difference was not statistically significant(P > 0.05);the knee joint function activity of group A and group B at 3 mo and 6 mo after operation was significantly higher than that before operation(P < 0.05);the limp,support,lock,instability,swelling,upstairs,squatting,pain and Lysholm score were compared between the two groups before and 6 mo after operation,and the difference was not statistically significant(P > 0.05);the scores of limp,support,lock,instability,swelling,upstairs,squatting,pain and Lysholm in group A and group B at 6 mo after operation were significantly higher than those before operation(P > 0.05);the surgical complication rate of group A was 2.63%,which was lower than 18.42% of group B,and the difference was statistically significant(P > 0.05).CONCLUSION Both small incision open reduction and internal fixation and arthroscopic high-strength nonabsorbable sutures can achieve good results in the treatment of anterior cruciate ligament tibial avulsion fractures.The operation time of arthroscopic high-strength non-absorbable sutures is slightly longer,but the complication rate is lower.

Clinical study on the surgical treatment of atypical Lisfranc joint complex injury

BACKGROUND Lisfranc injuries have not received much attention by orthopedic doctors in the past,and there is little related research on the diagnosis and treatment of these injuries.In recent years with the rise in foot and ankle surgery,doctors are now paying more attention to this type of injury.However,there is still a high rate of missed diagnosis due to insufficient attention causing treatment delays or inadequate treatments,which eventually result in greater sequelae;including long-term pain,arthritis,foot deformity etc.In particular,for cases with a mild Lisfranc joint complex injury,the incidence of sequelae is higher.AIM To select an active surgical treatment for an atypical Lisfranc joint complex injury and to evaluate the clinical efficacy of the surgical treatment.METHODS The clinical data of 18 patients,including 10 males and 8 females aged 20-64 years with Lisfranc injuries treated in our department from January 2017 to September 2019 were retrospectively analyzed.All patients were treated with an open reduction and internal fixation method using locking titanium mini-plates and hollow screws or Kirschner wires.X-ray images were taken and follow-up was performed monthly after the operation;the internal fixation was then removed 4-5 mo after the operation;and the American Orthopedic Foot and Ankle Society(AOFAS)score was used for evaluation on the last follow-up.RESULTS All patients were followed up for 6-12 mo.A good/excellent AOFAS score was observed in 88.9%of patients.CONCLUSION For atypical Lisfranc joint complex injuries,active open reduction and internal fixation can be performed to enable patients to obtain a good prognosis and satisfactory functional recovery.

Pulmonary thromboembolism after distal ulna and radius fractures surgery: A case report and a literature review

BACKGROUND Pulmonary thromboembolism(PTE)is a serious postoperative complication that can occur after a fracture.Generally,PTE is caused by the falling off of lower extremity deep vein thrombosis(LEDVT)after lower limb fracture surgery.LEDVT and PTE after upper extremity fracture surgery are very rare.PTE is one of the most common clinical causes of sudden death.Venous thromboembolism includes PTE and DVT.We experienced one case of LEDVT and PTE after distal ulna and radius fracture surgery.The purpose of our report is to raise awareness for orthopedic surgeons that PTE can occur after distal ulna and radius fracture surgery,and patients with high risk factors should be considered for prevention and treatment of thrombosis in a timely manner.CASE SUMMARY We report a 51-year-old Chinese male who had severe fractures of the left distal ulna,radius and little finger after a motorcycle accident.The patient underwent external fixation,open reduction and internal fixation.On the third post-operative day,computed tomographic pulmonary angiography showed PTE.Doppler ultrasonography showed thrombus formation in the bilateral posterior tibial veins.After a period of anticoagulation therapy,on the 25th d after the PTE,computed tomographic pulmonary angiography showed that thrombus in both sides of the pulmonary artery disappeared.Furthermore,about 4 mo after the PTE,thrombosis in the deep veins of the lower limbs disappeared.About 1 year after the surgery,X-rays showed good fracture healing,and the function of the wrist joint recovered well.CONCLUSION Though rare,PTE can occur after distal ulna and radius fracture surgery and patients with high risk factors should be considered for prevention and treatment of thrombosis in a timely manner.

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.

Radiographic evaluation of vascularity in scaphoid nonunions:A review

Scaphoid fractures,particularly those that occur more proximally,are unreliable in achieving union due to the retrograde blood supply of the scaphoid bone.Vascular compromise is associated with the development of nonunions and avascular necrosis of the proximal pole.Due to the tenuous blood supply of the scaphoid,it is imperative that the vascularity be assessed when creating diagnostic and treatment strategies.Early detection of vascular compromise via imaging may signal impending nonunion and allow clinicians to perform interventions that aid in restoring perfusion to the scaphoid.Vascular compromise in the scaphoid presents a diagnostic challenge,in part due to the non-specific findings on plain radiographs and computed tomography.Magnetic resonance imaging techniques have dramatically improved our ability to assess the blood supply to the scaphoid and improve time to intervention.This review aims to summarize these advances and highlights the importance of imaging in assessing vascular compromise in scaphoid nonunion and in reperfusion following surgical intervention.

Distal Radius Fracture: What Does the Patient Want?

Distal radius fractures are common and while historically most have been treated nonoperatively the frequency with which distal radius fractures are treated surgically is increasing. Criteria for considering surgical treatment are often based on radiographic appearance of the fracture. Less often discussed is patient preference: what do patients want. We investigated responses of a general population when presented with various treatment options following a hypothetical distal radius fracture. Many respondents chose nonoperative treatment even when told that surgery might result in a better outcome. This information can help during the shared decision-making process when discussing treatment options with a patient who presents with a distal radius fracture.

Surgical management of zygomatic complex fractures in a major trauma centre

Aim: To analyse the epidemiology, aetiology, and surgical management of zygomatic complex (ZMC) fractures in our major trauma centre, and to compare the number and location of fixation points and surgical access in our patient cohort with the literature. Methods: Retrospective analysis of all operative cases (Open Reduction and Internal Fixation) of zygomatic complex fractures over a one year period (2016). Results: A greater proportion of patients in our cohort (54%) were treated with one-point fixation compared to the literature, with the zygomaticomaxillary (ZM) buttress being the most popular fixation point (90%). ZM buttress and frontozygomatic (FZ) suture were the commonest choices for two-point fixations (70%). Buccal sulcus incision was used for ZM access in all cases. For FZ access, upper blepharoplasty incision was the most common (56%). For infra-orbital margin access, transconjunctival incision was the most common (75%). There was no significant association between number of fixation points and presence of associated injuries, impact of injury, or time to operation. There were no post-operative complications. Conclusion: A greater proportion of patients in our cohort were successfully treated with one point fixation compared to the literature, and fewer patients underwent orbital floor exploration and repair in our cohort compared to the literature. This study highlights the ongoing variation in the surgical management of ZMC fractures.
