Evaluation of functional outcome using dual plating in treatment of intraarticular distal humerus fractures in adults.

Of all the humerus fractures in adults, 30% are of the distal end of the bone. The dual plate is strong biomechanically. The current study was conducted at Al-Yarmouk Teaching Hospital, Baghdad, Iraq, between July 1, 2019 to July 1, 2021 to study the role of dual plating in intra-articular distal humerus fractures. Included were 20 adult patients, all with intra articular fracture of the distal humerus and treated and evaluated by open reduction and internal fixation technique using dual locking plating. Clinically the final results were assessed using the Mayo Elbow Performance Score (MEPS). The final results were observed to be excellent in 12 (60 %), good in 6 (30%), fair in 2 (10 %) patients, with no poor results recorded. One patient had transient ulnar neuropraxia which recovered spontaneously after six weeks and one patient developed superficial skin infection which responded to antibiotic treatment. The mean of MEPS was significantly higher after six months and one year than that after two weeks, two months, and four months of operation.

Impact of Lumbar Fusion Internal Fixation on Lumbar Disc Herniation in Young Patients: A Retrospective Study.

BACKGROUND Lumbar fusion and internal fixation techniques have shown promise in treating lumbar disc herniation (LDH), yet the impact on lumbar function in young patients remains unclear. This study aimed to investigate the impact of lumbar fusion on lumbar function in young patients. MATERIAL AND METHODS A retrospective analysis was conducted on 330 patients diagnosed with LDH admitted to our hospital. Patients were divided into 2 groups: a control group (n=264) that underwent a minimally invasive procedure with a keyhole lens, and a research group (n=66) that underwent lumbar fusion internal fixation. Clinical features and therapeutic outcomes were assessed using Oswestry Disability Index (ODI) and Japanese Orthopedic Association (JOA) Lumbar Scores before surgery and 12 months postoperatively. Additionally, intervertebral space height, degree of vertebral spondylolisthesis (grades I, II, and III), incidence of adverse effects, and treatment efficacy were measured pre-and post-surgically. RESULTS No significant difference in ODI and JOA scores was found between the groups before surgery (P>0.05). Postoperatively, the research group had lower ODI scores, higher JOA scores, and lower intervertebral space heights compared to the control group (P=0.001). While grade 1 and 2 spondylolisthesis showed slight improvement (P>0.05), a significant difference was observed in grade III spondylolisthesis between the 2 groups (P=0.001). Additionally, the research group had a lower incidence of adverse effects (P=0.049) and higher treatment efficacy, although the difference was not statistically significant (P>0.05). CONCLUSIONS Lumbar fusion with internal fixation produced better postoperative outcomes and fewer adverse effects than minimally invasive procedures in young patients with lumbar disc herniation.

Volar Locking Plate Fixation for Scaphoid Fractures: Surgical Technique

Scaphoid fractures are the most encountered carpal fracture. Unstable fractures with substantial comminution or bone loss, as well as scaphoid nonunions, may benefit from fixation using volar locking plates. This article presents a surgical technique for open reduction and internal fixation of scaphoid fractures using a volar locking plate and a non-vascularized autogenous cancellous bone graft from the distal radius.

Biomechanical characteristic differences of two new types of intramedullary nail devices in the treatment of comminuted intertrochanteric fractures of femur: a comparative study based on finite element analysis

ObjectiveGiven the recent application of two new types of intramedullary nail devices in the treatment of comminuted femoral intertrochanteric fractures (CFIFs), there is still a lack of deep understanding and comparative evaluation of their biomechanical properties. Therefore, this study aims to systematically compare the advantages and disadvantages of these two new devices with traditional proximal femoral nail antirotation (PFNA) and InterTan nails in the fixation of CFIFs through finite element analysis.MethodsBased on the validated finite element model, this study constructed an accurate CFIFs model. In this model, PFNA, InterTan nails, proximal femoral bionic nails (PFBN), and new intramedullary systems (NIS) were implanted, totaling four groups of finite element models. Each group of models was subjected to simulation tests under a vertical load of 2100 N to evaluate the displacement and Von Mises stress (VMS) distribution of the femur and intramedullary nail devices.ResultsUnder a vertical load of 2100 N, a comparative analysis of the four finite element models showed that the NIS device exhibited the most superior performance in terms of peak displacement, while the PFNA device performed relatively poorly. Although the NIS device had the highest peak stress in the femur, it had the smallest peak displacement of both the femur and intramedullary nail devices, and the peak stress was mainly concentrated on the lateral side of the femur, with significantly lower stress in the proximal femur compared to the other three intramedullary nail devices. In contrast, the PFBN device had the lowest peak stress in the femur, and its peak displacement of both the femur and intramedullary nail devices was also less than that of PFNA and InterTan nails.ConclusionThis study demonstrates that in the treatment of CFIFs, PFBN and NIS devices exhibit superior biomechanical performance compared to traditional PFNA and InterTan nail devices. Especially the NIS device, which can achieve good biomechanical results when fixing femoral intertrochanteric fractures with missing medial wall. Therefore, both PFBN and NIS devices can be considered reliable closed reduction and internal fixation techniques for the treatment of CFIFs, with potential clinical application value.

Biomechanical difference analysis of new and classic intramedullary nail devices in the treatment of basal femoral neck fractures: finite element analysis

ObjectiveThere is currently a lack of in-depth comparative evaluation regarding the biomechanical properties of novel intramedullary nail devices in the treatment of basal femoral neck fractures (BFNF). This study aims to utilize finite element analysis to compare the performance differences of two novel devices with traditional PFNA and InterTan nails in the fixation of BFNF.MethodsBased on a validated finite element model, this study constructed an accurate BFNF model and implanted four different intramedullary nail devices: PFNA, InterTan nail, PFBN (proximal femoral biomimetic nail), and NIS (novel intramedullary system). Under a vertical load of 2100N, the displacement and Von Mises stress (VMS) distribution of each group of models were evaluated through simulation testing.ResultsUnder a load of 2100N, the PFBN device exhibited the best performance in terms of displacement and peak stress, while PFNA performed poorly. The peak displacement of the NIS device was lower than that of PFNA and InterTan nails, while the peak stress of the InterTan nail was lower than that of PFNA and NIS.ConclusionThe PFBN device demonstrates stronger load-bearing and shear-resistant properties in the treatment of BFNF, and the NIS device also shows significant improvement in stability. Therefore, both the PFBN and NIS devices are reliable internal fixation techniques for the treatment of CFIFs, with potential clinical application prospects.

Biomechanical changes of oblique lumbar interbody fusion with different fixation techniques in degenerative spondylolisthesis lumbar spine: a finite element analysis

ObjectiveThere is a dearth of comprehensive research on the stability of the spinal biomechanical structure when combining Oblique Lumbar Interbody Fusion (OLIF) with internal fixation methods. Hence, we have devised this experiment to meticulously examine and analyze the biomechanical changes that arise from combining OLIF surgery with different internal fixation techniques in patients diagnosed with degenerative lumbar spondylolisthesis.MethodsSeven validated finite element models were reconstructed based on computed tomography scan images of the L3-L5 segment. These models included the intact model, a stand-alone (S-A) OLIF model, a lateral screw rod (LSR) OLIF model, a bilateral pedicle screw (BPS) OLIF model, an unilateral pedicle screw (UPS) OLIF model, a bilateral CBT (BCBT) OLIF model, and an unilateral CBT(UCBT) OLIF model. The range of motion (ROM), as well as stress levels in the cage, L4 lower endplate, L5 upper endplate, and fixation constructs were assessed across these different model configurations.ResultsS-A model had the highest average ROM of six motion modes, followed by LSR, UPS, UCBT, BPS and BCBT. The BCBT model had a relatively lower cage stress than the others. The maximum peak von Mises stress of the fixation constructs was found in the LSR model. The maximum peak von Mises stress of L4 lower endplate was found in the S-A model. The peak von Mises stress on the L4 lower endplate of the rest surgical models showed no significant difference. The maximum peak von Mises stress of the L5 upper endplate was found in the S-A model. The minimum peak von Mises stress of the L5 upper endplate was found in the BCBT model. No significant difference was found for the peak von Mises stress of the L5 upper endplate among LSR, BPS, UPS and UCBT models.ConclusionAmong the six different fixation techniques, BCBT exhibited superior biomechanical stability and minimal stress on the cage-endplate interface. It was followed by BPS, UCBT, UPS, and LSR in terms of effectiveness. Conversely, S-A OLIF demonstrated the least stability and resulted in increased stress on both the cage and endplates. Combining OLIF with BCBT fixation technique enhanced biomechanical stability compared to BPS and presented as a less invasive alternative treatment for patients with degenerative lumbar spondylolisthesis.

COMPARATIVE ASSESSMENT OF BONE FIXATION METHODS IN CRANIOFACIAL SURGERIES: A systematic review

Bone fixation plays a crucial role in craniofacial surgeries, being essential for the correction of cranial and facial deformities, as well as for stabilization after trauma or reconstructive surgery. This article presents a systematic review of the different bone fixation methods used in craniofacial surgeries, including plates and screws, rigid internal fixation, external fixation and biological techniques. The aim is to compare the efficacy, safety and clinical outcomes of these methods, providing valuable insights to guide clinical practice.

Treatment of posterolateral tibial plateau fractures: a narrative review and therapeutic strategy.

The posterolateral tibial plateau is crucial for maintaining knee stability during flexion, and fractures in this area often involve ligament and meniscus injuries, necessitating effective management. However, treating posterolateral tibial plateau fractures (PLF) poses significant challenges due to the complex anatomy. Therefore, this review aims to explore contemporary concepts of PLF, from identification to fixation, and proposes a comprehensive treatment strategy. In this article, the authors detail the injury mechanisms, fracture morphology, PLF classification systems, surgical approaches, and techniques for open reduction and internal fixation (ORIF) as well as arthroscopic-assisted internal fixation (ARIF). The findings indicate that PLF is typically caused by flexion-valgus forces, resulting in depression or split-depression patterns. For isolated PLF, the supra-fibular head approach is often preferable, whereas posterior approaches are more suitable for combined fractures. Additionally, innovative plates, particularly the horizontal belt plate, have shown satisfactory outcomes in treating PLF. Currently, the 'bicondylar four-quadrant' concept is widely used for assessing and managing the tibial plateau fractures involving PLF, forming the cornerstone of the comprehensive treatment strategy. Despite challenges in surgical exposure and implant placement, ORIF remains the mainstream treatment for PLF, benefiting significantly from the supra-fibular head approach and the horizontal belt plate. Furthermore, ARIF has proven effective by providing enhanced visualization and surgical precision in managing PLF, emerging as a promising technique.

The Application of Lag Screws and Digital Positioning Guide in Treating Sagittal Split Fracture of the Mandible.

Sagittal mandibular fractures are challenging to manage using traditional open reduction and internal fixation techniques due to the difficulty in manually reducing mandibular fragments and performing osteosynthesis on the lingual side. In addition, there is a risk of damaging dental roots with screws during fixation. In this case, the authors employed the lag screw technique combined with digitally guided surgery to effectively perform osteosynthesis on the fragments and avoid iatrogenic tooth and nerve injury.

A trans-eyebrow zig-zag approach for frontal bone fractures✰

Frontal bone fractures are amongst the most common facial fractures and surgical management, which has traditionally involved access via a coronal flap, can result in unsightly scarring, alopecia, paraesthesia, facial nerve weakness and temporal hollowing. Alternative approaches include use of endoscopically-assisted surgery, often through the eyebrow, which minimises the risk of unsightly scarring but may also sacrifice access in the process. In this technical note, we discuss a surgical technique for open reduction and internal fixation of fractures of the bone overlying the frontal sinus and supra-orbital rim, which the authors have not found in the literature, which involves the making of a “zig-zag” incision through the eyebrow in a trichophytic manner which reduces the risk of unsightly scarring whilst simultaneously allowing for sufficient surgical access to the fracture site.

Volar Locking Plate Fixation of Distal Radius Fractures: Surgical Technique

Distal radius fractures are one of the most common upper extremity fractures in orthopaedics. Unstable distal radius fractures are often managed with volar locking plates (VLP). However, fragment-specific fixation may be more appropriate for fractures of the dorsal rim, dorsal ulnar corner, isolated radial styloid, and small volar ulnar corner fragments. While the volar approach is most common, the surgeon should also be familiar with dorsal, radial, and extensile volar approaches. This article discusses a contemporary surgical technique for open reduction and internal fixation of distal radius fractures using VLP via the flexor carpi radialis approach.

Optimal screw orientation for fixation of coronal shear fractures: a biomechanical comparison

Coronal shear fractures of the capitellum are rare injuries which can be challenging to treat. The aim of this study was to compare the biomechanical properties of different internal screw fixation techniques for Dubberley type IA fractures of the capitellum. In this biomechanical study, Dubberley type IA fractures of the capitellum were created in 30 human fresh-frozen humeri. The specimens were then divided into 3 groups: fixation was either performed with 3×3.0mm headless cannulated compression screws (HCCSs) in anteroposterior (AP) orientation (AP group), 3×3.0mm HCCSs in posteroanterior (PA) orientation (PA group) or with 2×3.0mm HCCSs in PA orientation and 1×3.0mm HCCS in lateral orientation (LAT) group. Displacement under cyclic loading and ultimate load-to-failure were evaluated in all specimens. There was no significant difference in fragment displacement after 2000 cycles between AP and PA groups (0.8±0.5mm vs. 0.8±0.6mm; P=.987) or PA and LAT groups (0.8±0.6mm vs. 0.8±0.3mm; P=.966). LAT group showed the highest load-to-failure (548±250N) without reaching statistically significant difference to AP group (388±173N; P=.101). There was also no significant difference between AP and PA groups (388±173N vs. 422±114N; P=.649). Variations in screw placement had no statistically significant influence on cyclic displacement or load-to-failure in Dubberley Type IA fractures. However, fracture fixation in 2 planes-both the coronal and the sagittal plane-by adding a screw in a lateral to medial direction may be beneficial to increase primary stability.

Plate Fixation of Hamate Fractures in Fourth and Fifth Carpometacarpal Fracture Dislocations.

Traumatic dislocations of the fourth and fifth metacarpals, in conjunction with dorsal hamate fractures, are a common entity that can lead to the instability of the fourth and fifth carpometacarpal (CMC) joints. The fracture of the hamate, usually in a coronal dorsal shear configuration, can lead to the dorsal subluxation of the hamatometacarpal joint. Open reduction and internal fixation of the hamate bone with a dorsally applied buttress plate can re-establish a stable and congruent joint surface and anatomically align the articular surfaces of the small and ring finger CMC joints. We present a technique of internal fixation of the hamate to facilitate the reduction of the hamatometacarpal joints. Using a dorsal approach centered over the fourth and fifth CMC joints, the joint surfaces are directly visualized and subsequent fixation of the hamate is performed using a 1.3-mm T-plate to securely buttress its articular surface. This technique presents an approach to the multifaceted injury pattern of fourth and fifth CMC dislocations associated with a hamate fracture.

Cannulated screws fixation for nondisplaced femoral neck fractures: early versus late weight-bearing-a prospective analysis.

Nondisplaced intracapsular fractures (Garden I/II) are predominantly treated with an internal fixation technique. The purpose of the study is to identify the best rehabilitation protocol after internal fixation with 3 parallel cannulated screws. All patients operated on from 2016 to 2021 for femoral neck fractures by internal fixation with 3 cannulated screws were enrolled into this prospective study. The population was divided into two groups: Group A (n = 34) who followed a postoperative rehabilitation protocol involving full and immediate loading, and Group B (n = 22) who followed a postoperative rehabilitation protocol involving late full loading (after 30days). The two groups were compared with each other by mortality rate, postoperative complications and need for re-interventions. Functional outcome and quality of life were assessed at the minimum follow-up of 1year using the modified Harris Hip Score(HHS) and the Short form health survey (SF-12) questionnaire. Group A showed a lower complication rate (2.9% vs. 18.2%), a lower 1-year mortality rate (5.9% vs. 9.1%), a better perception of mental health status (SF12-MCS 56.2 vs. 51.4, p = 0.03) but a worse perception of one's physical health status (SF12-PCS 48.1 vs. 56.7, p < 0.01). The two groups were also statistically overlapping in terms of the functional outcome achieved after the intervention (HHS was 90.94 in Group A vs. 93.15 in Group B, p = 0.32). Postoperative complications, mortality and revision rate were higher in patients who followed a late-loaded rather than early loaded rehabilitation protocol. Functional outcome at 1-year survival is not significantly different. In nondisplaced intracapsular hip fractures treated with cannulated screws, an immediate full load should be preferred. Query.

Biomechanical study of a biplanar double support screw (BDSF) technique based on Pauwels angle in femoral neck fractures: finite element analysis.

The objective of the present study is to conduct a comparative analysis of the biomechanical advantages and disadvantages associated with a biplanar double support screw (BDSF) internal fixation device. Two distinct femoral neck fracture models, one with a 30° angle and the other with a 70° angle, were created using a verified and effective finite element model. Accordingly, a total of eight groups of finite element models were utilized, each implanted with different configurations of fixation devices, including distal screw 150° BDSF, distal screw 165° BDSF, 3 CLS arranged in an inverted triangle configuration, and 4 CLS arranged in a "α" configuration. Subsequently, the displacement and distribution of Von Mises stress (VMS) in the femur and internal fixation device were assessed in each fracture group under an axial load of 2100N. At Pauwels 30° Angle, the femur with a 150°-BDSF orientation exhibited a maximum displacement of 3.17mm, while the femur with a 165°-BDSF orientation displayed a maximum displacement of 3.13mm. When compared with the femoral neck fracture model characterized by a Pauwels Angle of 70°, the shear force observed in the 70° model was significantly higher than that in the 30° model. Conversely, the stability of the 30° model was significantly superior to that of the 70° model. Furthermore, in the 70° model, the BDSF group exhibited a maximum femur displacement that was lower than both the 3CCS (3.46mm) and 4CCS (3.43mm) thresholds. The biomechanical properties of the BDSF internal fixation device are superior to the other two hollow screw internal fixation devices. Correspondingly, superior biomechanical outcomes can be achieved through the implementation of distal screw insertion at an angle of 165°. Thus, the BDSF internal fixation technique can be considered as a viable closed reduction internal fixation technique for managing femoral neck fractures at varying Pauwels angles.

A novel surgical method for treating fractures of the middle third of the clavicle.

The clavicle is recognized as the bone most vulnerable to fractures. Moreover, approximately 80% of fractures occur in the middle third of the clavicle. Conservative treatment is associated with a higher rate of nonunion, while surgical treatment of fracture via internal fixation may have a variety of postoperative complications. Therefore, to improve patient satisfaction and reduce the complications related to internal fixation techniques, we modified the surgical approach to external fixation. The purpose of this study was to assess the modified intervention's prospects for clinical application. A total of 36patients with middle clavicle fractures were treated with screw-rod external fixation between April 2015 and October 2019. We observed the operative time, intraoperative blood loss, length of hospital stay, and fracture healing time. The patients were followed up regularly, and the clinical efficacy of the modified intervention was evaluated. Finally, the patients' shoulder function was assessed based on the disabilities of the arm, shoulder, and hand (DASH) score. For the screw-rod external fixation, the mean operative time was found to be 48.6 ± 6.8min, the intraoperative blood loss was 30.6 ± 17.2mL, the length of hospital stay was 4.5 ± 1.5days, and the fracture healing time was 2.8 ± 0.4months. Eventually, all the patients healed well, with the combined "excellent" and "good" rate of shoulder function being assessed to be as high as 94.44%. Furthermore, the DASH scores were all less than 10, with the average score being 4.65± 3.34. The screw-rod external fixation technique offers the advantages of convenience, reliability, and good aesthetics, suggesting that it could be used as an alternative treatment method for fractures of the middle third of the clavicle.

Advancements in pelvic ring fracture surgery: Assessing INFIX screw placement accuracy with CT navigation

The management of unstable pelvic ring fractures, typically resulting from high-energy trauma, presents a significant clinical challenge due to the complexity of injuries. While effective in many cases, the traditional stabilization methods are fraught with various complications that can significantly impact patient recovery and quality of life (QOL). This study aims to evaluate the efficacy and precision of the anterior subcutaneous internal fixator (INFIX) technique when used with intraoperative computed tomography (CT) navigation, a novel approach intended to mitigate the limitations of conventional treatment modalities.Our retrospective case series encompasses 43 patients who sustained traumatic pelvic injuries and were subsequently treated with the INFIX technique from December 2020 to January 2024. The focus of this analysis was to assess the accuracy of INFIX screw placement facilitated by intraoperative CT navigation.A total of 81 INFIX screws were inserted, and our study findings reveal a high level of precision in screw placement, with only one screw deviating, resulting in an inaccuracy rate of merely 1.2 %. This highlights the significant advantage provided by intraoperative CT navigation. The high level of accuracy not only enhances the stability of the pelvic fixation but also substantially reduces the risk of complications commonly associated with screw misplacement, such as abdominal damage, vascular injury, and issues related to incorrect hardware positioning.In conclusion, the integration of the INFIX technique with intraoperative CT navigation in the treatment of unstable pelvic ring fractures represents a significant advancement in orthopedic trauma surgery. This study provides compelling evidence supporting the efficacy and precision of this approach, suggesting its potential as a superior alternative to traditional fixation methods. Further research, ideally through prospective studies involving larger patient cohorts, is needed to validate these findings and explore the long-term implications of this technique on patient recovery and QOL.

A STUDY OF FUNCTIONAL OUTCOME IN THREE COLUMN FIXATION OF COMPLEX TIBIAL PLATEAU FRACTURES

Introduction: The treatment of complex tibial plateau fractures (TPF), especially those caused by high-energy trauma, remains a challenge in many respects. Tibial plateau fractures are one of the commonest periarticular fractures. These fractures include 1% of all fractures and 8% of fractures in elderly. Motor vehicle accidents account for the majority of these fractures in younger individuals with good bone stock, but in elderly individuals these fractures may result from simple fall due to osteopenic bone. Conservative methods may result in malunion and articular congruity cannot be restored. Surgical treatment can regain articular congruity and restore mechanical alignment, and can allow early range of motion. Open reduction and internal fixation techniques had been associated with wound complications. Aim Of The Study: To evaluate functional outcome in patients of complex tibial plateau fractures treated by three column fixation. Materials and Methods: In our institution 20 patients with displaced tibial plateau fractures with posterior column involvement were selected for the study. This is a prospective study done from AUGUST 2023 to APRIL 2024(9 months).Patients were evaluated with X rays (AP and lateral views) and Computed Tomography (axial, coronal, sagittal with 3D reconstruction views). Fractures classified based on 3 column concept classification. Mean follow up period was 6 months .Functional and radiological outcome was assessed using functional knee score , modified rasmussen score and WOMAC score. Inclusion Criteria: 1. Patients admitted with complex tibial plateau fractures involving medial, lateral and posterior column of tibia. 2. Both sexes 3. Age 20-60 yrs. Exclusion Criteria: 1) Bad skin status of the fractured site. 2) Patients with co morbidities not fit for surgery. 3) Patients with neurovascular deficit. 4) Patients not willing for surgery. Results:In our study, 70% of the patients were in active productive age group (30-50 years). 85% of the patients were male. The fractures were left sided in 75% patients. 85% patients in study sustained injury due to road traffic accident. 80% cases in the study were type 5 schatzker type 5 fractures and all the cases included in the study were 3 column fractures. 8 cases out of 20 cases in the study required epidural analgesia instead of a repeat spinal as the duration of the surgery was longer. Conclusion: To conclude,3 column fixation in high energy displaced tibial plateau fractures with three column fractures resulted in Good clinical and radiological outcomes.

Comparison of the clinical outcomes between proximal femoral nail anti-rotation with cement enhancement and hemiarthroplasty among elderly osteoporotic patients with intertrochanteric fracture

BackgroundThe proximal femoral nail anti-rotation (PFNA) with cement enhancement enhances the anchorage ability of internal fixation in elderly with osteoporotic intertrochanteric fracture. However, whether it is superior to hemiarthroplasty is still controversial. The present study aimed to determine which treatment has better clinical outcomes among older patients.MethodsWe retrospectively analyzed 102 elderly patients with osteoporosis who developed intertrochanteric fractures and underwent PFNA combined with cement-enhanced internal fixation (n = 52, CE group), and hemiarthroplasty (n = 50, HA group) from September 2012 to October 2018. All the intertrochanteric fractures were classified according to the AO/OTA classification. Additionally, the operative time, intraoperative blood loss, intraoperative and postoperative blood transfusion rates, postoperative weight-bearing time, hospitalization time, Barthel Index of Activities Daily Living, Harris score of hip function, visual analog (VAS) pain score, and postoperative complications were compared between the two groups.ResultsThe CE group had significantly shorter operative time, lesser intraoperative blood loss, lower blood transfusion rate, and longer postoperative weight-bearing time than the HA group. The CE group had lower Barthel’s Index of Activities of Daily Living, lower Harris’ score, and higher VAS scores in the first and third months after surgery than the HA group, but no difference was observed between the two groups from 6 months to 12 months. There was no significant difference in the total post-operative complications between the two groups.ConclusionThe use of PFNA combined with a cement-enhanced internal fixation technique led to shorter operative time and lesser intraoperative blood loss and trauma in elderly patients as compared to HA.
