Comparative efficacy of proximal femoral nail vs dynamic condylar screw in treating unstable intertrochanteric fractures

BACKGROUND Among the most frequent hip fractures are trochanteric fractures,which usually occur from low-energy trauma like minor falls,especially in older people with osteoporotic bones.AIM To evaluate the treatment efficacy of dynamic condylar screws(DCS)and proximal femoral nails(PFN)for unstable intertrochanteric fractures.METHODS To find pertinent randomized controlled trials and retrospective observational studies comparing PFN with DCS for the management of unstable femoral intertrochanteric fractures,a thorough search was carried out.For research studies published between January 1996 and April 2024,PubMed,EMBASE,Scopus,Web of Science,Cochrane Library,and Google Scholar were all searched.The complete texts of the papers were retrieved,vetted,and independently examined by two investigators.Disputes were settled by consensus,and any disagreements that persisted were arbitrated by a third author.RESULTS This study included six articles,comprising a total of 173 patients.Compared to the DCS,the PFN had a shorter operation time[mean difference(MD):-41.7 min,95%confidence interval(95%CI):-63.04 to-20.35,P=0.0001],higher success rates with closed reduction techniques[risk ratio(RR):34.05,95%CI:11.12-104.31,P<0.00001],and required less intraoperative blood transfusion(MD:-1.4 units,95%CI:-1.80 to-1.00,P<0.00001).Additionally,the PFN showed shorter fracture union time(MD:-6.92 wk,95%CI:-10.27 to-3.57,P<0.0001)and a lower incidence of reoperation(RR:0.37,95%CI:0.17-0.82,P=0.01).However,there was no discernible variation regarding hospital stay,implant-related complications,and infections.CONCLUSION Compared to DCS,PFN offers shorter operative times,reduces the blood transfusions requirements,achieves higher closed reduction success,enables faster fracture healing,and lowers reoperation incidence.

Comparitive Study between Proximal Femoral Nailing and Dynamic Hip Screw in Intertrochanteric Fracture of Femur

Background: Internal fixation is appropriate for most intertrochanteric fractures. Optimal fixation is based on the stability of fracture. The mainstay of treatment of intertrochanteric fracture is fixation with a screw slide plate device or intramedullary device. So it is a matter of debate that which one is the best treatment, dynamic hip screw or proximal femoral nailing. Method: A prospective randomized and comparative study of 2 years duration was conducted on 60 patients admitted in the Department of Orthopedics in our hospital with intertrochanteric femur fracture. They were treated by a dynamic hip screw and proximal femoral nail. Patients were operated under image intensifier control. The parameters studied were functional outcome of Harris hip score, total duration of operation, rate of union, amount of collapse. These values were statistically evaluated and two tailed p-values were calculated and both groups were statistically compared. Result: The average age of our patient is 67.8 years. Among the fracture, 31% were stable, 58% were unstable, 11% were reverse oblique fracture. The average blood loss was 100 and 250 ml in PFN and DHS group, respectively. In PFN there was more no. of radiation exposure intraoperatively. The average operating time for the patients treated with PFN was 45 min as compared to 70 min in patients treated with DHS. The patients treated with PFN started early ambulation as they had better Harris Hip Score in the early period (at 1 and 3 months). In the long term both the implants had almost similar functional outcomes. Conclusion: In our study we have found that the unstable pattern was more common in old aged patients with higher grade of osteoporosis and PFN group has a better outcome in this unstable and osteoporotic fracture. PFN group has less blood loss and less operating time compared to DHS group. In PFN group patients have started early ambulation compared to DHS group.

Does proximal femoral nail antirotation achieve better outcome than previous-generation proximal femoral nail?

BACKGROUND There are few studies in the literature comparing the clinical outcomes and radiographic results of proximal femoral nail(PFN)and proximal femoral nail antirotation(PFNA)for pertrochanteric femoral fracture(PFF)in elderly patients.AIM To evaluate both clinical and radiographic outcomes after fixation with PFN and PFNA in an elderly patient population.METHODS One hundred fifty-eight patients older than 65 years with PFF who underwent fixation with either PFN or PFNA were included.Seventy-three patients underwent fixation with PFN,whereas 85 were fixed with PFNA.The mean follow-up was 2.4 years(range,1-7 years).Clinical outcome was measured in terms of operation time,postoperative function at each follow-up visit,and mortality within one year.Radiographic evaluation included reduction quality after surgery,Cleveland Index,tip-apex distance(TAD),union rate,time to union,and sliding distance of the screw or blade.Complications including nonunion,screw cutout,infection,osteonecrosis of the femoral head,and implant breakage were also investigated.RESULTS Postoperative function was more satisfactory in patients who underwent PFNA than in those who underwent PFN(P=0.033).Radiologically,the sliding difference was greater in PFN than in PFNA patients(6.1 and 3.2 mm,respectively,P=0.036).The rate of screw cutout was higher in the PFN group;eight for PFN(11.0%)and two for PFNA patients(2.4%,P=0.027).There were no differences between the two groups in terms of operation time,mortality rate at one year after the operation,adequacy of reduction,Cleveland Index,TAD,union rate,time to union,nonunion,infection,osteonecrosis,or implant breakage.CONCLUSION Elderly patients with PFF who underwent PFNA using a helical blade demonstrated better clinical and radiographic outcomes as measured by clinical score and sliding distance compared with patients who underwent PFN.

Arthroplasty vs proximal femoral nails for unstable intertrochanteric femoral fractures in elderly patients: a systematic review and metaanalysis

BACKGROUND Proximal femoral nails(PFNs)are the most common method for the treatment of unstable intertrochanteric femoral fractures(IFFs),but postoperative bed rest is required.There is a large amount of blood loss during the operation.Osteoporosis in elderly patients may cause nonunion of fractures and other complications.Arthroplasty can give patients early weight bearing and reduce financial burden,but whether it can replace PFNs remains controversial.AIM To compare the clinical outcomes of arthroplasty and PFNs in the treatment of unstable IFFs in elderly patients.METHODS A search was conducted in the PubMed,Embase,and Cochrane Library databases and included relevant articles comparing arthroplasty and PFN.The search time was limited from January 1,2005 to November 1,2020.Two investigators independently screened studies,extracted data and evaluated the quality according to the inclusion and exclusion criteria.According to the research results,the fixed effect model or random effect model were selected for analysis.The following outcomes were analyzed:Harris Hip score,mortality,complications,operation time,blood loos,hospital stay,weight-bearing time,fracture classification and type of anesthesia.RESULTS We analyzed four randomized controlled trials that met the requirements.A total of 298 patients were included in these studies.According to the AO/OTA classification,there are 20 A1 types,136 A2 types,42 A3 types and 100 unrecorded types.Primary outcome:The Harris Hip Score at the final follow-up of the PFN group was higher[mean difference(MD):9.01,95%confidence interval(CI):16.57 to 1.45),P=0.02].There was no significant difference between the two groups in the rate of overall mortality[risk ratio(RR):1.44,P=0.44]or the number of complications(RR:0.77,P=0.05).Secondary outcomes:blood loss of the arthroplasty group was higher(MD:241.01,95%CI:43.06–438.96,P=0.02);the operation time of the PFN group was shorter(MD:23.12,95%CI:10.46–35.77,P=0.0003);and the length of hospital stay of the arthroplasty group was shorter[MD:0.97,95%CI:1.29 to 0.66),P<0.00001].There was no difference between the two groups in the type of anesthesia(RR:0.99).There were only two studies recording the weight-bearing time,and the time of full weight bearing in the arthroplasty group was significantly earlier.CONCLUSION Compared with PFN,arthroplasty can achieve weight bearing earlier and shorten hospital stay,but it cannot achieve a better clinical outcome.Arthroplasty cannot replace PFNs in the treatment of unstable IFFs in elderly individuals.

Proximal Femoral Nailing: Technical Difficulties and Results in Trochanteric Fractures

Background: Proximal femoral nailing in communited intertrochanteric fractures is increasingly becoming popular in view of superior biomechanics and prevention of varus collapse associated with Dynamic hip screw. However, technical difficulties and implant related complications have been described with this technique, thus we need more studies to address these issues. Our study aims to understand technical difficulties involved in proximal femoral nailing, and specifically analyses neck shaft angle at follow-up indicating varus collapse and also to compare results of stable and unstable fractures. Materials and Methods: In this study, patients who presented to the Orthopedic Unit of Dr. TMA Pai Hospital (An associated hospital of Manipal University, Manipal) with trochanteric fractures included and treated with proximal femoral nailing. The technical difficulties involved with surgical procedure and techniques adapted to overcome such difficulties were recorded. All patients were followed up for a period of 2 years and final outcome assessment included the number of shortening, neck shaft angle and harris hip score. Results: 41 patients (mean age 71) who underwent proximal femoral nailing from January 2004 to December 2009 were included in the study, 38 patients completed 2-year follow-up. The technical difficulties we faced were divided into 3 categories, difficulties in securing entry point and guide wire placement especially when greater trochanter and piriform fossa were gathered, reduction was lost while passing nail, and finally difficulties faced during placement of hip screws. In all except one, neck shaft angle of more than 130 degrees was achieved, and this was also maintained in the final follow-up (Mean 131.9 degrees). All fractures were united, with mean shortening of 2 mm. Conclusions: Although PFN is technically required, with a proper technique PFN gives excellent clinical results with almost negligible varus collapse even in unstable trochanteric fractures. Regarding the techniques, reaming the proximal part of femur adequately and observing the nail passage with image carefully are important in placing the nail correctly, while, placement of lag screw in the inferior part of neck in anterior posterior projection and central in lateral projection reduces risk of implant failure.

Effect of proximal femur nail anti-rotation on unstable intertrochanteric fractures: A prospective observational study

Objective:To assess the effect of proximal femur nail anti-rotation on the functional and radiological outcome of unstable intertrochanteric fractures.Methods:This prospective observational study was conducted in the orthopedic department of a tertiary care hospital.Altogether 86 patients with unstable intertrochanteric fractures treated with proximal femur nail anti-rotation between January 2010 and January 2015 were included.Patients were followed in the outpatient clinic at regular intervals after discharge to assess the radiological union of fractures and complications.The functional outcomes were evaluated after 2 years by Harris hip score.Results:All patients achieved a radiological union of fractures after a mean duration of 24.6 weeks.The follow up showed 23 complications(systemic and local).Eight patients developed urinary tract infections,and three patients developed chest infections,two patients had screw cut-out,one patient had knee stiffness,one patient developed superficial surgical site infection,and four patients developed varus collapse and shortening subsequently.The two year follow up showed that 69(80.2%)patients had an excellent and good functional outcome according to Harris hip score.Conclusions:With lower complication rates,proximal femur nail is a valid and reasonable option especially in treating unstable intertrochanteric fractures.

Proximal Femoral Nail in Reverse Trochanteric Femoral Fractures: An Analysis of 53 Cases at One Year Follow-Up

Treatment of reverse oblique trochanteric femoral fractures poses a lot of challenges. There have been proponents of intramedullary devices as well as extramedullary devices. We present the results of proximal femoral nailing surgery performed for reverse obliquity intertrochanteric fractures using two proximal lag screws and a nail of 250 mm. There is prospective study of fifty three patients with AO/OTA 31 A-A3 fractures being treated by proximal femoral nailing in our institute after seeking approval from the Hospital ethics board. The quality of the reduction, the operative time, complications and the functional status of the patients were the parameters on which the results were evaluated. The mean Harris hip score was 76.66 (range 70 - 93) and the mean Barthel activity score was 16.21 (range 12 - 20). The average surgical time was 50 minutes and the mean consolidation time was 11.5 weeks. Intramedullary nailing with proximal femoral nails seems to be a good option in the treatment of reverse obliquity intertrochanteric fractures as against the various existing options available for the management.

Comparative study of intertrochanteric fracture fixation using proximal femoral nail with and without distal interlocking screws

BACKGROUND Intertrochanteric(IT)fracture is one of the most common fractures seen in an orthopaedic practice.Proximal femoral nailing(PFN)is a common modality of fixing IT femur fracture.We retrospectively studied whether a PFN with two proximal lag screws can be done without distal interlocking screws in the 31-A1 and 31-A2 fracture patterns according to the Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association(AO/OTA)guidelines for IT femur fractures.AIM To compare the outcomes of IT fractures(AO/OTA 31-A1 and 31-A2)treated by PFN with and without distal interlocking screws.METHODS We carried out a retrospective study of 140 patients in a tertiary care centre who had AO/OTA type 31-A1 and 31-A2 IT fractures.We divided the patients into two groups,in which one of the groups received distal interlocking screws(group 1)and the other group did not(group 2).The subjects were followed up for a mean period of 14 mo and assessed for radiological union time,fracture site collapse,mechanical stability of implant,and complications associated with the PFN with distal interlocking and without distal interlocking.Then,the results were compared.RESULTS PFN without distal interlocking screws has several advantages and gives better results over PFN with distal interlocking screws in the AO/OTA 31-A2 fracture pattern.However,similar results were observed in both groups with the fracture pattern AO/OTA 31-A1.In patients with fracture pattern AO/OTA 31-A2 treated by PFN without distal interlocking screws,there were minimal proximal lockrelated complications and no risk of distal interlock-related complications.The operative time,IITV radiation time and time to radiological union were reduced.These patients also had better rotational alignment of the proximal femur,and the anatomy of the proximal femur was well maintained.It was also noted that in the cases where distal interlocking was performed,there was a gradual decrease in neck shaft angle,which led to varus collapse and failure of bone-implant construct in 21.40%.CONCLUSION In fracture pattern AO/OTA 31-A2,PFN without distal interlocking had better results and less complications than PFN with distal interlocking.

Proximal Femoral Nailing: Getting the Trajectory Right

Getting the trajectory of the proximal femoral nail in the right direction is essential to achieve a good result in the technically demanding surgery of proximal femoral fracture. Either an inappropriate starting point or a failure to match the chosen implant’s lateral entry angle may cause coronal plane deformity after trochanteric entry nailing. The lateral view is the critical view for localization of the proper starting point. For the right execution of the surgery, getting the trajectoy right is fully under the control of the surgeon and should always be attempted.

Reduction Aid in Proximal Femoral Fractures: The Thigh Support

Reducing the Unstable Intertrochanteric Fractures in a closed manner is challenging especially in the old and aged people with co morbidities. We provide a simple reducing aid to achieve the fracture reduction. This will protect your surgical resident’s or operating theatre practitioner’s back in maintaining the reduction throughout the procedure and continuing with the procedure of cephalomedullary nailing. It will also facilitate in the better rehabilitation of the patient with minimal morbidity and offer a good radiographic view.

A comparative analysis of distal locked and unlocked long proximal femoral nail antirotation (PFNA-II) in the fixation of stable intertrochanteric fractures

Purpose:Long proximal femoral nail anti-rotation (PFNA-II) is a preferred implant in recent years for fixation of pertrochanteric fractures,especially in osteoporotic patients.The purpose of this study is to prospectively investigate the effect of distal locking in long PFNA-II fixation of stable intertrochanteric fractures.Methods:A total of 58 patients with isolated stable intertrochanteric fractures and treated in our hospital during the study period of 2017–2019 by distal locked or unlocked long PFNA-II fixation were included in this study.Patients who had multiple injuries or open fractures were excluded.There were 40 female and 18 male patients,with 33 affecting the left side and 25 the right side.Of them,31 belonged to the distal locked group (group A) and 27 to the unlocked group (group B).Surgical procedures and implants used in both groups were similar except for the distal locking of the nails.General data (age,gender,fracture side,etc.) showed no significant difference between two groups (allp > 0.05).The intraoperative parameters like operative time,radiation exposure and follow-up parameters like functional and radiological outcomes were recorded and compared.Statistical tests like the independent samplest-test Fischer’’s exact and Chi-square test were used to analyze association.Results:The distribution of the fractures according to AO/OTA classification and 31A1.2 type of intertrochanteric fractures were most common in our study.All the included fractures united and the average functional outcome in both groups were good and comparable at the end of one year.The operative time (mL,107.1 ± 12.6vs.77.0 ± 12.0,p < 0.001) and radiation exposure (s,78.6 ± 11.0vs.40.3 ± 9.3,p < 0.001) were significantly less among the patients in group B.Fracture consolidation,three months after the operative procedures,was seen in a significantly greater proportion of patients in group B (92.6%vs.67.7%,p = 0.025).Hardware irritation because of distal locking bolt was exclusively seen in group A,however this was not statistically significant (p = 0.241).Conclusion:We conclude that,in fixation of stable intertrochanteric fractures by long PFNA-II nail,distal locking not only increases the operative time and radiation exposure but also delays the fracture consolidation and increases the chances of hardware irritation,and hence is not required.

A rare complication of pelvic perforation by an excessive medial slide of the helical blade after treatment of an intertrochanteric fracture with proximal femoral nail anti-rotation:A case report and literature review

Intertrochanteric fractures have become a severe public health problem in elderly patients.Proximal femoral nail anti-rotation(PFNA)is a commonly used intramedullary fixation device for unstable intertrochanteric fractures.Pelvic perforation by cephalic screw is a rare complication.We reported an 84-year-old female who fell at home and sustained an intertrochanteric fracture.The patient underwent surgery with PFNA as the intramedullary fixation device.Routine postoperative examination revealed medial migration of the helical blade that eventually caused pelvic perforation.We performed a cemented total hip arthroplasty as the savage procedure.At the latest follow-up of 12 months after total hip arthroplasty,the patient had no pain or loosening of the prosthesis in the left hip.Pelvic perforation should be considered when choosing PFNA as the intramedullary fixation device,especially in patients with severe osteoporosis wherein the helical blade can be easily inserted during the operation.The lack of devices to avoid oversliding of the helical blade in PFNA is an unreported cause of this complication and should be considered in such cases.

Comparison of Clinical Effect of PFNA and Internal Fixation with Anatomical Locking Plate of Proximal Femur in Treatment of Intertrochanteric Fracture of Femur

Purpose:To investigate the clinical value of proximal femoral nail antirotation and anatomical locking plate of proximal femur in the treatment of intertrochanteric fracture of femur.Methods:The study group is treated with PFNA internal fixation.The control group is treated by internal fixation with anatomical locking plate of proximal femur.Results:The time of operation,the amount of intraoperative bleeding and the time of fracture healing in the study group are significantly less than those in the control group.The incidence rate of complication in the study group(3.23%)is significantly lower than that in the control group(17.2%).Data comparison shows P<0.05.Conclusion:The curative effect and prognosis for patients with intertrochanteric fracture of femur treated by PFNA internal fixation are more ideal.

Total hip arthroplasty following the failure of intertrochanteric nailing:First implant or salvage surgery?

BACKGROUND Proximal femur fractures,including both intracapsular(femoral neck fractures)and extracapsular fractures(intertrochanteric femoral fractures,IFFs),affect around 1.5 million people per year worldwide.Mechanical failures of intertrochanteric nailing in IFFs could be managed with revision total hip arthroplasty(THA).AIM To describe the surgical complexity and the procedure-related complication rates in patients with trochanteric nailing failure and treated with THA.METHODS Patients referred to our level I trauma center between April 2012 and July 2018 with failed cephalomedullary nailing following trochanteric fractures were retrospectively recruited.All patients underwent a salvage surgical procedure,i.e.,cephalomedullary nail removal and conversion to THA.The same surgical and anesthesiology team performed the surgical procedures under spinal anesthesia.All patients underwent clinical and radiographic follow-ups for at least 24 mo.Complications and re-operations were recorded.RESULTS Seventy-four patients met the inclusion criteria(male:29;female:45;mean age:73.8-years-old;range:65-89)and were included in the current study.The average operative time was 117 min(76-192 min).The average blood loss was 585 mL(430-1720 mL).Among the 74 patients,43(58.1%)required transfusion of three or more blood units.Two patients died within the 4th d after surgery because of pulmonary embolism,and 1 patient died 9 mo after surgery due to ischemic myocardial infarction.The complication rate in the 71 patients who completed the minimum 24-mo follow-up was 22.5%.In 3 cases out of 71(4.2%)periprosthetic acetabular fracture was observed during the followup.One of these periacetabular fractures occurred intraoperatively.An intraoperative periprosthetic femur fracture was observed in 5 patients out of 71(7.0%).Four of these patients needed a re-operation to fix the fracture with plates and cerclages;in one of these patients,femoral stem revision was also necessary.In 4 patients out of 71(5.6%),an early THA dislocation was observed,whereas in 1 case(1.4%)a late THA dislocation was observed.Three patients out of 71(4.2%)developed a periprosthetic joint infection during the study follow-up.CONCLUSION The present study demonstrated that salvage options for IFF fixation failure are complex procedures with a relevant intraoperative and postoperative complication rate.
