Treatment of a femoral neck fracture combined with ipsilateral femoral head and intertrochanteric fractures: A case report

BACKGROUND This article presents a rare case of a complex hip fracture involving the ipsilateral femoral neck,trochanter,and femoral head,that was accompanied by hip dislocation.Currently,there is no established standard treatment method for this specific type of fracture.Therefore,it is crucial to comprehensively consider factors such as patient age,fracture type,and degree of displacement to achieve a successful outcome.CASE SUMMARY A 38-year-old man sustained a comminuted fracture of his right hip as a result of a car accident.The injuries included a fracture of the femoral head,a fracture of the femoral neck,an intertrochanteric fracture of the femur,and a posterior dislocation of the hip on the same side.We opted for a treatment approach combining the use of a proximal femoral locking plate,cannulated screws,and Kirschner wires.Following the surgery,we developed an individualized rehabil-itation program to restore patient limb function.CONCLUSION For this complex fracture,we selected appropriate internal fixation and for-mulated individualized rehabilitation,which ultimately achieved good results.

Application of Grooved Negative Pressure Drainage Tube in Surgical Stabilization of Rib Fractures

Objective: To explore the application value of disposable grooved negative pressure drainage tubes in rib fracture incision and internal fixation. Methods: Seventy-five patients admitted to our Department of Trauma Surgery from June 2022 to April 2024 who underwent rib fracture osteotomy and internal fixation were selected. According to the types of drainage tubes left in the patients after the operation, they were divided into the observation group (35 cases who were left with disposable grooved negative pressure drainage tubes) and the control group (40 cases who were left with closed silicone thoracic drainage tubes). Comparison of chest drainage, pain, postoperative complications, secondary chest penetration rate, drain placement time, hospitalization time, and treatment costs were compared between the two groups. Results: The total postoperative chest drainage volume of the observation group was less than that of the control group (P < 0.05);the degree of pain, the incidence of postoperative complications, and the rate of secondary chest puncture in the observation group were lower than that of the control group three days after the operation (P < 0.05);and the time of drain placement in the observation group was shorter than that of the control group (P < 0.05). Conclusion: The application of disposable grooved negative pressure drainage tubes in rib fracture incision and internal fixation can significantly improve patients’ postoperative pain and discomfort, reduce complications, lower the rate of secondary chest penetration, promote patients’ postoperative recovery, decrease the amount of postoperative chest drainage, and shorten the time of drain placement, which is worthy of clinical promotion and application.

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.

Surgical treatment ofpatients with severe non-flail chest rib fractures

BACKGROUND Many patients have inadequate long-term analgesia,respiratory distress,and hypoxemia due to a long-standing substantial smoking history or the presence of primary pulmonary diseases;analgesic treatment is not valid in these patients.Even if the imaging findings of rib fractures are relatively mild,rib fractures may cause severe position limitation,respiratory distress,and hypoxemia.AIM To investigate the curative effect of surgical treatment for patients with severe non-flail chest rib fractures.METHODS A total of 78 patients from our hospital with severe noncontinuous thoracic rib fractures from September 2016 to September 2018 were enrolled in our study.Thirty-nine patients underwent surgical treatment,and 39 underwent conservative treatment.The surgical treatment group received surgery performed with titanium plates,and the screws were inserted with open reduction and internal fixation.The conservative treatment group received analgesia and symptomatic treatment.The pain scores at 72 h,1 wk,2 wk,4 wk,6 wk,3 mo,and 6 mo were compared,and the SF-36 quality of life scores were compared atthe 3rd and 6th months.RESULTS Pain relief in the surgical group was significantly better than that in the conservative group at each time point(72 h,1 wk,2 wk,4 wk,6 wk,3 mo,and 6 mo after surgery,P<0.001).The SF-36 scores were significantly higher in the surgical group than in the conservative group at 1 mo and 6 mo(P<0.05).CONCLUSION Patients with severe non-flail chest rib fractures have a better quality of life following surgical treatment than following conservative treatment,and surgical treatment is also useful for relieving pain.We should pay more attention to the physiological functions and clinical manifestations of patients with severe rib fractures.In patients with non-flail chest rib fractures,surgical treatment is feasible and effective.

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.

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.

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.

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.
