Clinical effect of operative vs nonoperative treatment on humeral shaft fractures:Systematic review and meta-analysis of clinical trials

BACKGROUND Whether operation is superior to non-operation for humeral shaft fracture remains debatable.We hypothesized that operation could decrease the nonunion and reintervention rates and increase the functional outcomes.AIM To compare the clinical efficacy between operative and nonoperative approaches for humeral shaft fractures.METHODS We searched the PubMed,Web of Science,ScienceDirect,and Cochrane databases from 1990 to December 2023 for clinical trials and cohort studies comparing the effects of operative and conservative methods on humeral shaft fractures.Two investigators independently extracted data from the eligible studies,and the other two assessed the methodological quality of each study.The quality of the included studies was assessed using the Cochrane risk bias or Newcastle-Ottawa Scale.The nonunion,reintervention and the overall complications and functional scores were pooled and analyzed using Review Manager software(version 5.3).RESULTS A total of four randomized control trials and 13 cohort studies were included,with 1285 and 1346 patients in the operative and nonoperative groups,respectively.Patients in the operative group were treated with a plate or nail,whereas those in the conservative group were managed with splint or functional bracing.Four studies were assessed as having a high risk of bias,and the other 13 were of a low risk of bias according to the Newcastle-Ottawa Scale or Cochrane risk bias tool.The operative group had a significantly decreased rate of nonunion[odds ratio(OR)0.30;95%CI:0.23 to 0.40,reintervention(OR:0.33;95%CI:0.24 to 0.47),and overall complications(OR:0.62;95%CI:0.49 to 0.78)].The pooled effect of the Disabilities of Arm,Shoulder,and Hand score showed a significant difference at 3[mean difference(MD)-8.26;95%CI:-13.60 to-2.92],6(MD:-6.72;95%CI:-11.34 to-2.10),and 12 months(MD:-2.55;95%CI:-4.36 to-0.74).The pooled effect of Visual Analog Scale scores and the Constant-Murley score did not significantly differ between the two groups.CONCLUSION This systematic review and meta-analysis revealed a trend of rapid functional recovery and decreased rates of nonunion and reintervention after operation for humeral shaft fracture compared to conservative treatment.

Functional Outcomes of Adult Tibia Shaft Fractures Treated with Solid Intramedullary Nails versus Hollow Nails: A Systematic Review

Introduction: The management of fractures of the tibia shaft is an important aspect of orthopaedic care, and the selection of the surgical method for fixation can substantially impact patient outcomes. The current review aims to compare the outcomes of adult tibia fractures treated with solid nails to those treated with hollow nails. Methods: A search on Scopus, PubMed, and Cochrane Library, using three keywords (Outcome, Tibia shaft fractures, Nail) was conducted in April 2023. Results were compiled and two independent reviewers screened and selected eligible articles After removing duplicates, titles and abstracts were read to exclude ineligible studies. Full-text articles of the remaining papers were read to select eligible studies which were further critically appraised to ascertain their methodological quality. The data extracted from the selected papers were synthesized using a combination of pooling of results, tests of statistical difference (t-test and chi-square) and narrative synthesis methods. Results: A total of 2295 articles were obtained from the databases and citation searching. A total of 9 papers were identified as eligible and included in the review. Findings revealed that there is no statistical difference in the outcomes of tibia fractures treated with either solid or hollow nail groups such as duration of surgery (p = 0.541), rate of delayed and non-union (p = 0.342), and rate of surgical site infections (p = 0.395). Conclusion: Intramedullary nailing of tibia shaft fractures with either solid or hollow nails have similar functional outcomes.

Missed diagnosis of femoral deep artery rupture after femoral shaft fracture: A case report

BACKGROUND Vascular injury is a rare complication of femoral shaft fractures,and rupture of the deep femoral artery is more difficult to diagnose because of its anatomical location and symptoms.Despite its low incidence,deep femoral artery rupture can lead to life-threatening outcomes,such as compartment syndrome,making early identification and diagnosis critical.CASE SUMMARY A 45-year-old male patient was admitted to our hospital due to right lower limb trauma in a car accident,with complaints of severe pain and swelling on his right thigh.X-ray demonstrated a right femoral shaft fracture.During preparation for emergency surgery,his blood pressure and blood oxygen saturation dropped,and sensorimotor function was lost.Computed tomography angiography was performed immediately to confirm the diagnosis of rupture of the deep femoral artery and compartment syndrome,so fasciotomy and vacuum-assisted closure were performed.Rhabdomyolysis took place after the operation and the patient was treated with appropriate electrolyte correction and diuretic therapy.Twenty days after the fasciotomy,treatment with the Hoffman Type II External Fixation System was planned,but it was unable to be immobilized internally based on a new esophageal cancer diagnosis.We kept the external fixation for 1 year,and 3 years of follow-up showed improvement of the patient’s overall conditions and muscle strength.CONCLUSION For patients with thigh swelling,pain,anemia,and unstable vital signs,anterior femoral artery injury should be highly suspected.Once diagnosed,surgical treatment should be performed immediately and complications of artery rupture must be suspected and addressed in time.

Radial nerve recovery following closed nailing of humeral shaft fractures without radial nerve exploration: A retrospective study

BACKGROUND Radial nerve palsy due to humeral shaft fracture is the most common peripheral nerve injury associated with long bone fractures.An antegrade nailing surgical technique is becoming popular for the fixation of these fractures with minimal invasiveness.We analyzed nerve recovery in patients with humeral shaft fracture and radial nerve palsy treated with humeral nail fixation without nerve exploration.AIM To assess the radial nerve recovery rate and time from humeral shaft fracture with surgical treatment using close nailing.METHODS We retrospectively collected data of patients who underwent undergone surgical nail fixation for humeral shaft fractures between October 1,2016,and March 31,2020.Subsequently,we analyzed the primary or secondary radial nerve palsy recovery rate and radial nerve motor function recovery time.RESULTS The study included 70 patients who underwent surgical treatment for closed-or Gustilo type I open humeral shaft fractures using a nail fixation technique without radial nerve exploration.The patients suffered from primary(n=5)and secondary(n=5)radial nerve palsy.A 100%radial nerve recovery rate was achieved.The mean recovery time was 4.3 mo.CONCLUSION The study results indicate full recovery of radial nerve palsies from humeral shaft fracture using close nailing treatment.Surgeons need not be concerned about the occurrence of permanent nerve palsies.

Comparative Study between the Elastic Nail versus Hip Spica Cast in Early Treatment of Pediatric Femoral Shaft Fractures

Introduction: Femoral shaft fractures are among the most common pediatric injury, which have the highest incidence among other pediatric fractures, and treatment of them carries a lot of controversies. Aim of the study: To compare the outcome of fixation of femoral shaft fracture by elastic nail with Spica cast. Patient and method: This prospective comparative study was carried out in Sulaimani Teaching Hospital, in the period from the 10th of December 2011 to the 10th of June 2012, for two groups of children whose ages were between 4 - 12 years (average 6.61 years), sustained traumatic femoral shaft fractures with follow-up period of about 6 months. The first group was consisting of 30 children treated by Elastic Intramedullary Nail, while the second group was consisted of 30 children treated by hip Spica. The selection was made on random bases. Results: Age range was between 4 - 12 years and showed male predominance in both groups with ratio of about 2:1 while fracture site showed predominance of the midshaft pattern in both groups. This study showed highly significant deference (P value of 0.001) between the two groups (Spica group of 3 days versus Nail group median of rate 4.5 days) in the admission period. Our sample showed shortening of about 2 cm in 2 case in the Nail group (6.7%) versus 6 cases (20%) in Spica group. We reported 4 cases of wound infection (13.3%) and 4 cases of pin site irritation (13.3%) in nail group. A higher rate of malunion was observed in the Spica group (10 cases more than 10° angulation in coronal plane) while the Nail group reported 2 case more than 10° in coronal plane. The mean operative time for Nail group was 55 minutes while in Spica group was 30 minutes. We reported shorter time to start mobilization and walking with support or independently in the nail group (weight bearing time 7.2 weeks) compared with the Spica casting group (weight bearing time 7.5 weeks). Conclusion: Elastic nail fixation yields better outcome for femoral shaft fracture in form of easier child handling, parent’s satisfaction, and maintaining acceptable fracture alignment.

Intramedullary bone pedestal formation contributing to femoral shaft fracture nonunion:A case report and review of the literature

BACKGROUND Femoral shaft fracture is a commonly encountered orthopedic injury that can be treated operatively with a low overall delayed/nonunion rate.In the case of delayed union after antegrade or retrograde intramedullary nail fixation,fracture dynamization is often attempted first.Nonunion after dynamization has been shown to occur due to infection and other aseptic etiologies.We present a unique case of diaphyseal femoral shaft fracture nonunion after dynamization due to intramedullary cortical bone pedestal formation at the distal tip of the nail.CASE SUMMARY A 37-year-old male experienced a high-energy trauma to his left thigh after coming down hard during a motocross jump.Evaluation was consistent with an isolated,closed,left mid-shaft femur fracture.He was initially managed with reamed antegrade intramedullary nail fixation but had continued thigh pain.Radiographs at four months demonstrated no evidence of fracture union and failure of the distal locking screw,and dynamization by distal locking screw removal was performed.The patient continued to have pain eight months after the initial procedure and 4 mo after dynamization with serial radiographs continuing to demonstrate no evidence of fracture healing.The decision was made to proceed with exchange nailing for aseptic fracture nonunion.During the exchange procedure,an obstruction was encountered at the distal tip of the failed nail and was confirmed on magnified fluoroscopy to be a pedestal of cortical bone in the canal.The obstruction required further distal reaming.A longer and larger diameter exchange nail was placed without difficulty and without a distal locking screw to allow for dynamization at the fracture site.Post-operative radiographs showed proper fracture and hardware alignment.There was subsequently radiographic evidence of callus formation at one year with subsequent fracture consolidation and resolution of thigh pain at eighteen months.CONCLUSION The risk of fracture nonunion caused by intramedullary bone pedestal formation can be mitigated with the use of maximum length and diameter nails and close follow up.

Correlative Factors Research of Tibial Shaft Fracture with Ipsilateral Posterior Malleolar Crack Fractures

Background:Missed diagnosis rate of spiral tibia shaft fracture with posterior malleolus crack fracture(PMCF)is high in the clinical.However,the mechanism and related factors of fracture are still unclear.Moreover,PMCF has been observed in other types of tibial shaft fractures.Objective:To explore the correlative factors of tibial shaft fracture with ipsilateral PMCF,decrease the rate of clinical missed diagnosis,strengthen the effective fixation of PMCF,and reduce the incidence of traumatic arthritis.Methods:From September 2014 to May 2019,we collected 137 tibiofibular fracture.Only 68 cases involved in ankle joint CT examination and were retrospectively analyzed.The patients were divided into posterior malleolus group(30 cases)and non-posterior malleolus group(38 cases)according to whether come up PMCF or not.The posterior malleolus group contained 24 males and 6 females,27-77(47.57±11.79)years old,the non-posterior malleolus group contained 23 males and 15 females,18-85(48.71±13.84)years old.The gender,age,location,fibula fracture and tibial shaft fracture classification were observed for univariate and multivariate analysis.Results:The probability of PMCF was higher with right tibial shaft fracture(OR=3.6995%CI:1.13-12.08 P<0.05);the probability of PMCF following distal fibular fracture was higher than that without fibular fracture(OR=11.3695%CI:1.72-75.05 P<0.05);the probability of PMCF with type A tibial shaft fracture was higher than type C(OR=4.8295%CI:1.19-19.58 P<0.05).Conclusion:Right type A tibial shaft fracture accompanied by distal fibular fracture are very important factors related to PMCF,which needs highly attention to avoid clinical missed diagnosis.

To compare and evaluate 3 kinds of treatments of pediatric closed femoral shaft fractures.Methods Seventy-nine patients were divided into 3 groups and treated using hip spica casting after skeletal traction,unilateral multifunctional fixation and plate fixation.The result were evaluated according to clinical function,time to union,complications,radiology examination and the economic cost.Results Both time to union and economic cost of the external fixation group were shorter than that of the skeletal traction group and plate fixation group.Conclusion The unilateral multi-functional external fixation is an ideal solution to pediatric close femoral shaft fractures.7 refs,3 tabs.

Radial Head Dislocation Associated with an Ipsilateral Open Type II Gustilo-Anderson Fracture of the Radial Shaft

Radial head dislocation associated with an ipsilateral radial shaft fracture is a rare lesion, even more so for open lesions. Few cases have been found in the literature. We report this case due to its exceptional nature and discuss the mechanism of onset. A twenty-five-year-old patient presented with a dislocation of the radial head associated with a GUSTILO ANDERSON type II open fracture of the radial shaft following an occupational accident. He was managed twenty-four hours after the trauma. The mechanism was a direct blow. The dislocation was reduced by external manoeuvre following open reduction of the radial shaft. The fracture was stabilized by two Kirschner wires following reduction. The result at 12 months was satisfactory from a clinical and radiological standpoint.

Treatment of pediatric femoral shaft fractures by stainless steel and titanium elastic nail system： A randomized comparative trial

Purpose： Literature suggests that the lower modulus of elasticity of titanium makes it ideal for use in children compared with stainless steel. Better fracture stability was observed in association with tita- nium nails on torsional and axial compression testing. However, stainless steel nails are stiffer than ti- tanium counterparts, which may provide a rigid construct when fixing paediatric femoral shaft fractures. Complications have been observed more frequently by various researchers when titanium nails are used for fracture fixation in patients with increasing age or weight. The concept of this study was to compare the functional outcome after internal fixation with titanium elastic nail system and stainless steel elastic nail system in paediatric femoral shaft fractures. Methods： The study was conducted on 34 patients admitted in the department of orthopaedics, LLRM Medical College ＆ SVBP Hospital, Meerut, India from January 2013 to August 2014. We included patients aged 5-12 years with fracture of the femoral shaft, excluding compound fractures, pathological fractures and other lower limb fractures. Patients were treated by titanium （n = 17） or stainless steel （n - 17） elastic nail system and followed up for one year. The clinical parameters like range of motion at hip and knee joints, time to full weight bearing on the operated limb and radiological parameters like time to union were compared between two groups. A special note was made of intra- and post-operative complications. Functional outcomes were analysed according to Flynn criteria. Results： Based on the Flynn criteria, 59% of patients had excellent results, 41% had satisfactory results, and no one showed poor results. There was no clinically significant difference between the two groups with respect to time to union and full weight bearing. But the incidence of puncture of the opposite cortex while inserting the nail and trying to advance it through the diaphysis during operation is greatly different. Only one such case was observed in titanium group but five in stainless steel group. Conclusion： Majority of paediatric femoral shaft fractures are now treated operatively by elastic stable intramedullary nails. Operative intervention results in a shorter hospital stay and has economic and social benefits over conservative treatment. The cost of stainless steel nail is one third the cost of tita- nium nail. However, the clinico-radiological results are not significantly different between titanium and stainless steel nails at one year follow-up as observed by our study.

Fracture Union in Closed Interlocking Nail in Humera Shaft Fractures

Background： Fracture shaft humerus is a major cause of morbidity in patients with upper extremity injuries. The aim of this study was to evaluate the outcome of interlocking nail in humeral shaft fractures. Methods： This study was conducted in the Department of Orthopedic Surgery in SMS and R Sharda University from January 2010 to November 2013. Seventy-eight patients were recruited from emergency and out-patient department having a close fracture of humerus shaft. All patients were operated under general anesthesia and closed reamed interlocking nailing was done. All patients were followed for 9 months. Results： Out of 78 patients, 69 patients underwent union in 90-150 days with a mean of I 10.68 days. Complications found in four patients who had nonunion, and five patients had delayed union, which was treated with bone grafting. All the patients were assessed clinically and radiologically for fracture healing joint movements and implant thilure. The results were excellent in 88.46% and good in 6.41% patients. Complete subjective, functional, and clinical recovery had occurred in almost 100% of the patients. ConcLusions： The results of the present study indicates that in the presence of proper indications, reamed antegrade intramedullary interlocked nailing appears to be a method of choice for internal fixation ofosteoporotic and pathologic fractures.

Pediatric femoral shaft fractures treated by flexible intrameduUary nailing

Background： Nowadays pediatric femoral fractures are more commonly managed with operative treatment rather than conservative treatment because of more rapid recovery and avoidance of prolonged immobilization. Children between the ages of 5-13 years are treated either by traction plus hip spica and flexible/elastic stable retrograde intramedullary nail, or external fixators in the case of open fractures. The aim of this study is to evaluate the outcome of pediatric femoral shaft fractures treated by stainless steel flexible intramedullary nail in children between 5 and 13 years of age. Methods： There were 32 cases of femoral shaft fractures which were all fixed with stainless steel flexible intramedullary nail under fluoroscopy. Long leg cast was applied at the time of fixation. Partial weight bearing was started 2 weeks after surgery. Patients were evaluated in follow-up study to observe the alignment of fracture, infection, delayed union, nonunion, limb length discrepancy, motion of knee joint, and time to unite the fracture. Results： We were able to follow up 28 out of 32 patients. The patients were 8.14 years of age on average. The mean hospital stay after operation was 4 days and fracture union time was 9.57 weeks. There were 3 cases of varus angulation, 2 cases of anterior angulation, and 4 cases of limb lengthening. Conclusion： Patients aged between 5 and 13 years treated with flexible intramedullary nail for closed femoral shaft fracture have rapid union and recovery, short rehabilitation period, less immobilization and psychological impact, and cost-effective.

Indirect reduction technique using a distraction support in minimally invasive percutaneous plate osteosynthesis of tibial shaft fractures

Purpose： To describe an indirect reduction technique during minimally invasive percutaneous plate osteosynthesis （MIPPO） of tibial shaft fractures with the use of a distraction support. Methods： Between March 2011 and October 2014, 52 patients with a mean age of 48 years （16-72 years） sustaining tibial shaft fractures were included. All the patients underwent MIPPO for the fractures using a distraction support prior to insertion of the plate. Fracture angular deformity was assessed by goniometer measurement on preoperative and postoperative images. Results： Preoperative radiographs revealed a mean of 7.6°（1.2°-28°） angulation in coronal plane and a mean of 6.8°（0.5°-19°） angulation in sagittal plane. Postoperative anteroposterior and lateral radio graphs showed a mean of 0.8°（0°-4.0°） and 0.6°00-3.6°） of varusvalgus and apex anterior/posterior angulation, respectively. No intraoperative or postoperative complications were noted. Conclusions： This study suggests that the distraction support during MIPPO of tibial shaft fractures is an effective and safe method with no associated complications.

Biomechanical Study of the Fixation Strength of Anteromedial Plating for Humeral Shaft Fractures

Background： Open reduction and internal fixation with plate and screws are the gold standard for the surgical treatment of humeral shaft fractures, this study was to compare the mechanical properties ofanteromedial, anterolateral, and posterior plating for humeral shaft fractures. Methods： A distal third humeral shaft fracture model was constructed using fourth-generation sawbones （#3404, composite bone）. A total of 24 sawbones with a distal third humeral shaft fracture was randomly divided into three Groups： A, B, and C （n = 8 in each group） for anteromedial, anterolateral, and posterior plating, respectively. All sawbones were subjected to horizontal torsional fatigue tests, horizontal torsional and axial compressive fatigue tests, four-point bending fatigue tests in anteroposterior （AP） and mediolateral （ML） directions and horizontal torsional destructive tests. Results： In the horizontal torsional fatigue tests, the mean torsional angle amplitude in Groups A, B, and C were 6.12°, 6.53°, and 6.81°. In horizontal torsional and axial compressive fatigue tests, the mean torsional angle amplitude in Groups A, B, and C were 5.66°, 5.67°, and 6.36°. The mean plate displacement amplitude was 0.05 mm, 0.08 mm, and 0.10 mm. Group A was smaller than Group C （P 〈 0.05）. In AP four-point bending fatigue tests, the mean plate displacement amplitude was 0.16 ram, 0.13 ram, and 0.20 mm. Group B was smaller than Group C （P 〈 0.05）. In ML lbur-point bending fatigue tests, the mean plate displacement amplitude were 0.16 mm, 0.19 ram, and 0.17 ram. In horizontal torsional destructive tests, the mean torsional rigidity in Groups A, B, and C was 0.82, 0.75, and 0.76 N·m/deg. The yielding torsional angle was 24.50°, 25.70°, and 23.86°. The mean yielding torque was 18.46, 18.05. and 16.83 N·m, respectively. Conclusions： Anteromedial plating was superior to anterolateral or posterior plating in all mechanical tests except in AP four-point bending fatigue tests compared to the anterolateral plating group. We can suggest that anteromedial plating is a clinically safe and effective way for humeral shaft fractures.

Comparison of two kinds of intramedullary nails in the treatment of femoral shaft fractures in adults

Intramedullary nails have been widely used in treating femoral shaft fractures. However, end caps falling into soft tissue intraoperatively may cause trouble to surgeons, prolong operative time and increase radiation exposure. Additionally, difficulties may be encountered when removing nails because of callus formation over the nail tip. We performed a prospective study to compare two types of nails in managing femoral shaft fractures. Methods Group I consisted of seventy-four patients with unilateral femoral shaft fractures treated with cannulated interlocking anatomical femoral intramedullary nails. Group II consisted of seventy-eight patients treated with cannulated interlocking anatomical femoral intramedullary nails with tail wires. The patients＇ ages, fracture severity, duration of operation, fluoroscopy time, blood loss and falls of end caps into soft tissue were recorded. Nails were removed after fracture healing. The duration of operation and blood loss during nail removal were recorded. Results There were no significant differences between groups with respect to age and fracture severity （P 〉0.05）. End caps fell into soft tissue 17 times in 15 cases in group I and 21 times in 16 cases in group I1. An average of seven minutes was spent recovering a lost cap in group I. In group II, all lost caps were recovered immediately. The duration of operation and fluoroscopy time in group II was significantly less than in group I （P 〈0.05）. Asymptomatic palpable nodules were detected in 4 cases in group I1. Nail removals were performed on 58 patients in group I and 69 patients in group I1. The duration of operation, blood loss and complications in group II were less than in group I （P〈0.05）. Conclusion Intramedullary nails with tail wires facilitate both fracture fixation and nail removal, which can be used to treat femoral shaft fractures with less radiation exposure, shorter surgical time and fewer complications.

Fracture union in percutaneous Kirschner wire fixation in paediatric tibial shaft fractures

Purpose： To evaluate the efficacy of intramedullary Kirschner wires for the treatment of unstable tibial shaft fractures in children. Methods： This prospective study was conducted at the Department of Orthopaedic Surgery in Maharishi Markandeshwar Medical College from June 2005 to June 2010. Sixty-six children having closed fracture of the tibial shaft with a mean age of 7.7 years （range, 2-14 years） were recruited from emergency and outpatient department. They were treated with percutaneous intramedullary Kirschner wires. The clinical results of our study were rated on the basis of the criteria of union, nonunion, delayed union or malunion. All children were followed for one year. Results： Children achieved union in a mean time of 8 weeks （range, 6-10 weeks）. Postoperatively, three children （4.55%） had delayed union, one （1.52%） valgus deformity of lower leg, three （4.55%） post- operative knee pain and twelve （18.18%） skin irritation at pin site. Wires were removed after 8-22 weeks without any complications. No patient was lost to follow-up. The results were excellent in 95.45% and good in 4.55% children. Conclusion： This technique is cost-effective, simple, quick to perform, safe and reliable and avoids pro- longed hospitalization with good results.

Treatment of ipsilateral femoral neck and shaft fractures

Objective：To investigate the clinical characteristics, treatment options and causes of misdiagnosis of ipsilateral femoral neck and shaft fractures. Methods： Among 20 patients with ipsilateral femoral neck and shaft fractures, 19 were treated operatively and 1 was treated conservatively. Sixteen cases of femoral shaft fractures were treated by open reduction and internal fixation with compressive plate, and 2 cases were treated with interlocking intramedullary nailing. Eighteen femoral neck fractures were treated with cannulated screws. Another patient was treated with proximal femoral nail to fix both the neck and shaft. Delayed diagnosis for femoral neck frac-tures occurred in 2 cases preoperatively. Results： A total of 19 patients were followed up. The follow up period ranged from 5 to 48 months with an average of 15 months. All the fractures were healed. Conclusion： For case of femoral shaft fracture caused by high energy injury, an AP pelvic film should be routinely taken. Once the femoral neck fracture is recognized, operative reduction and fixation should be performed in time. Femoral neck and shaft fractures should be fixed separately.

The efficacy of augmentative anti-rotational plating plus decortication and autogenic bone grafting for aseptic nonunion after intramedullary nailing of femoral shaft fracture

Background:Femoral interlocking intramedullary(IM)nailing fixation is an effective method for the treatment of femoral shaft fractures.Aseptic nonunion of femoral shaft fracture after IM nailing is uncommon.Currently,the treatment for aseptic femoral shaft nonunion is controversial.The aim of this study was to investigate the clinical effect of augmentative antirotational plating plus decortication and autogenic bone grafting for aseptic femoral shaft nonunion after IM nailing failure.Methods:A retrospective study was conducted on 25 cases of aseptic femoral shaft fracture nonunion treated with IM nailing from January 2015 to August 2019.All patients were treated by leaving the nail in situ,debridement of nonunionsites,decortication,autogenous iliac bone grafting,and augmentative antirotational plating fixation.The time to fracture union and complications were recorded.Results:All patients were followed up for 12–18 months.The union rate after revision surgery was 100%.The average union time was 5.5months(range,4-10).Subjective pain symptoms had disappeared in all patients.There were no incision infections or internal fixator fatigue fractures.Average scores of the physical function and bodily pain components of the SF-36 were 95.5(range,91-98)and 94.1(range,90-97),respectively.No other obvious complications occurred postoperatively.Conclusion:Augmentative antirotational plating plus decortication and autogenic bone grafting is an excellent choice for treating femoral shaft fracture nonunion after IM nailing;this approach has an overall high union rate and few complications.

Treatment of long-segment fracture in middle-up part of femoral shaft with long proximal femoral nail anti-rotation of AO/ASIF

Objective To investigate the operative method and evaluate the clinical outcomes of long proximal femoral nail anti-rotation (PFNA-long) in treating long-segment fracture in middle-up part of femoral bone.Methods From June 2006 to
