Comparison of the outcome of dynamic hip screw versus proximal femoral nail for treatment of intertrochanteric femoral fractures among elderly patients.

Objective: To compare the outcome of DHS versus PFNA for treatment of intertrochanteric femoral fractures (IFFs) among elderly patients. Study Design: Randomized Clinical Trial. Setting: Sheikh Zayed Hospital, Lahore. Period: 2-03-2022 to 2-09-2022. Methods: In total 90 patients fulfilling inclusion criteria were registered after approval from the ethical review committee of the hospital. Every patient provided written informed consent. Patients were allotted to each group (Group A = PFNA, Group B = DHS) using lottery method. Patients were operated upon by a single surgical team. Data was obtained VIA questionnaires designed for pre- operative period, immediate post-operative period, 1 and 3 months follow up. Patients were interviewed and evaluated by blind researchers at each stage. Harris hip score was used to assess the functional outcomes. Results: In 90 patients (45 in each), 36.2% (n=17) were male in PFNA group and 63.8% (n=30) in DHS group and 65.1% (n=28) were female in PFNA and 34.9% (n=15) in DHS group, p=0.011. Mean age of PFNA group was calculated as 66.00± 3.41 years and mean age of DHS group was 66.80±3.71 years (p=0.714). Distribution of BMI was 28.14+6.20kg/m2 in PFNA group and 27.47+6.24kg/m2 in DHS group, p=0.612. Distribution of Harris hip score at 1 month was 31.11+4.08 in PFNA group and 30.11+4.18 in DHS group, p=0.254 and Harris hip score at 3 months was 88.68+1.23 in PFNA group and 81.68+0.95 in DHS group, p=0.000. Conclusion: We concluded that PFN is superior to DHS in treating Boyd and Griffin type II intertrochanteric fractures of femur. It’s only a matter of time that PFN becomes the new gold standard for these fractures.

Clinical outcomes of post-surgery osteoporosis treatment in elderly intertrochanteric fracture patients: a prospective study

Background: This study aims to evaluate the clinical and functional outcomes of administering zoledronic acid in elderly patients undergoing surgical management of hip fractures. The goal is to assess the impact on mortality, postoperative complications, and functional recovery as measured by the modified Harris hip score. Methods: A prospective study was conducted over 18 months at a tertiary care center in New Delhi, India, involving 42 patients aged 60 and above with intertrochanteric femur fractures. Patients received surgical fixation and standard postoperative care. Zoledronic acid (5 mg) was administered intravenously three months post-surgery. Data on demographics, injury-to-surgery interval, fracture type, DEXA score, and functional outcomes were collected at follow-ups of 6 weeks, 3 months, 6 months, and 12 months. Results: The mean age of participants was 72.67 years. Zoledronic acid administration was associated with a 9.5% mortality rate. Functional outcomes, measured by the modified Harris hip score, significantly improved from a mean of 42.14 at 6 weeks to 77.68 at 12 months (p<0.001). Younger patients (<70 years) had significantly better scores at 3 months compared to older patients (>80 years). However, no significant differences were observed at 6 and 12 months. The mean modified Harris hip scores did not differ significantly between patients with osteopenia and osteoporosis at any time point. Additionally, the type of surgical fixation (intramedullary versus extramedullary) showed no significant impact on functional outcomes. Conclusions: Zoledronic acid administration in elderly hip fracture patients may reduce mortality and enhance functional recovery. The study supports its use in postoperative care to improve outcomes, although larger, randomized controlled studies are needed to confirm these findings. The results suggest that zoledronic acid can be an effective adjunct therapy in managing osteoporosis-related hip fractures in the geriatric population.

Functional outcome of treatment of fracture intertrochanteric femur by using proximal femoral nail antirotation II

Background: The elderly are most frequently affected by intertrochanteric fractures, which have a major effect on the medical community and society at large. In 2003, AO introduced the proximal femoral nail anti-rotation device, which was further improved and named proximal femoral nail antirotation II (PFNA II) in 2009. Methods: This study was conducted from December 2020 to August 2022. The 60 cases of proximal femoral nail anti-rotation II-managed intertrochanteric femur fractures were assessed. Results: In the present study, 24 patients (40%) had type IV (Evan’s) fractures. Right hip was involved in 30 patients (50%). Meantime for clinic-radiological union was 20 weeks. There was complication rate of 2.08% as helical blade protrusion and non-union, 2.08% as helical blade protrusion, 2.08% as blade backout, 4.17% as superficial infection and 4.17% as lateral wall fracture. Seven patients expired postoperatively within 3 months while 5 patients lost during follow Up. After a 6-month follow-up, the Harris hip grade was used to evaluate 48 instances. Of these, 8 cases (16.67%) had an excellent score, 29 cases (60.42%) had a good score, 7 cases (14.58%) had a fair score, and 4 cases (8.33%) had a poor score. Thirty-seven of the 48 cases had reached the one-year follow-up mark. Thus, of the 37 patients assessed, 11 cases (29.73%) had excellent Harris hip grades, 19 cases (51.35%) had good scores, 4 cases (10.81%) had fair scores, and 3 cases (8.11%) had poor scores at the end of a one-year follow-up. Conclusions: Even in rural populations, PFN A-II is a better, safer implant with a low rate of complications for treating stable and unstable intertrochanteric femur fractures.

Comparison of two surgical methods for the treatment of intertrochanteric fractures of the femur in elderly patients with knee osteoarthritis

To explore the difference in the effectiveness between proximal femoral nail anti-rotation(PFNA) and proximal femoral locking compression plate(PFLCP) of intertrochanteric fracture in the elderly patients combined with knee osteoarthritis. The clinical data of 65 intertrochanteric femoral fractures combined with knee osteoarthritis between June 2015 and February 2021 were retrospectively analyze. They were divided into two groups according to the different surgical methods. PFNA group was composed of 36 patients, 12 males and 24 females, aged from 61to 88 years old with an average of (77.0±6.4)years old. There were 17 cases of left injury and 19 cases of right injury. According to modified Evans classification, there were 3 cases of typeⅡ, 19 cases of type Ⅲ, 10 cases of type Ⅳ, and 4 cases of type Ⅴ. PFLCP group was composed of 29 patients, 11 males and 18 females, aged from 60 to 92 years old with an average of (78.8±6.5) years old. There were 14 cases of left injury and 15 cases of right injury.According to modified Evans classification, there were 2 cases of typeⅡ, 18 cases of type Ⅲ, 7 cases of type Ⅳ, and 2 cases of type Ⅴ. Comparison of operation time, intraoperation blood loss, postoperative bed time, incidence of postoperative complications, Harris score at 6 months and 1 year postoperation. All 65 patients were followed up ranging from 12 to 24 months with an average of (16.9±3.6) months. In the PFNA and PFLCP groups, the operation time was respectively (57.6±6.8) min and (77.4±6.5) min, the intraoperative blood loss was (128.3±50.3) ml and (156.3±23.9) ml, postoperative bed time was (4.0±2.5) days and (8.1±2.0) days, Harris score at 6 months postoperative was (45.3±8.6) points and (36.3±7.0) points. There were significant differences between two groups(P<0.05). Incidence of postoperative complications was 19.4%(7/36)and 34.5%(10/29), Harris score at 1 year postoperative was (60.8±6.7) points and (59.0±8.1) points.There was no significant difference between the two groups(P>0.05). Compared with PFLCP, PFNA treatment of elderly patients with knee osteoarthritis between the femoral intertrochanteric fractures shorter surgical time, less intraoperative blood loss, bed rest after surgery, short-term hip function recovery better, when the affected knee joint can tolerate traction, can be used as a priority.

The role of post-traumatic antifibrinolysis in the perioperative blood management of elderly patients with intertrochanteric fractures treated with PFNA: A randomised controlled trial

BackgroundThis study aimed to evaluate the efficacy and safety of posttraumatic antifibrinolytic therapy with repeated doses of intravenous tranexamic acid (IV-TXA) in reducing perioperative hidden blood loss (HBL) in elderly intertrochanteric femur fracture (IFF) patients. Method112 elderly IFF patients who were admitted to our department from March 2020 to May 2021 were randomized to receive 100 ml of normal saline (Control group) or 1.5 g of TXA (TXA group) intravenously q12 h from postadmission day 1 (PAD1) to PAD3. Hemoglobin (Hb), hematocrit (Hct), fibrinogen degradation product (FDP), D-dimer (D-D), and coagulation parameters were recorded from PAD1 to postoperative day 3 (POD3). HBL was calculated using the gross formula and recorded as the primary outcome. ResultThe patients in TXA group had lower preoperative hidden blood loss(HBL), decline of hemoglobin(ΔHb), FDP (on PAD3), and D-D (on PAD3) compared with control group, while no difference was found in postoperative HBL, postoperative ΔHb and allogeneic blood transfusion (ABT) rate. In subgroup analyses, it was observed that patients who received the intervention within 24 h of injury and between 24 and 72 h of injury exhibited significantly lower preoperative HBL and ΔHb in the TXA group compared with the control group. Furthermore, the reduction in HBL and ΔHb was more pronounced in the former group. While for patients who received the intervention beyond 72 h after injury, no significant differences were observed in preoperative HBL and ΔHb between the two groups. Similarly, no significant differences were noted in postoperative HBL and ΔHb between the TXA and control groups across all subgroups. Additionally, no significant differences were identified in the incidence of venous thromboembolism (VTE) and mortality within one year between the two groups. ConclusionPost-traumatic antifibrinolytic therapy with repeated doses of intravenous TXA is effective and safe in reducing perioperative HBL for elderly IFF patients, especially for patients injured within 24 h.

Risk Factors for Early Implant Failure in Geriatric Intertrochanteric Fractures Treated with Twin Interlocking Derotation and Compression Screw Cephalomedullary Nail (InterTAN).

Intertrochanteric hip fractures in elderly patients are a significant cause of morbidity and mortality, with increasing incidence due to the aging population. Despite advancements in intramedullary nailing (IMN) technology, fixation failure remains a concern. This study aims to evaluate pre-and postoperative radiographic risk factors for varus collapse in geriatric intertrochanteric fractures treated with twin interlocking derotation and compression screw cephalomedullary nail (InterTAN, Smith & Nephew). This retrospective study included patients over 60 years with AO 31A1 and 31A2 intertrochanteric femur fractures treated with InterTAN at a tertiary referral center from August 2012 to August 2017. Patients with high-energy fractures, AO 31A3 fractures, or those requiring open reduction were excluded. Data on demographics, fracture classification, implant sizes, imaging studies, and follow-up were collected. Radiographic assessments included Chang's medial cortical support concept, tip-apex distance (TAD), calcar-referenced TAD (CalTAD), neck-shaft angles (NSA), and screw placement according to Cleveland zones. Varus collapse was defined as a >5° change in NSA within three months postoperatively. Multivariate logistic regression analysis was used to identify risk factors for varus collapse. The study included 136 patients with a mean age of 79.8 years, of whom 38.2% were male. The early postoperative tipapex distance (TAD) averaged 21.9mm, with 30.1% of patients experiencing varus collapse greater than 5°. Positive medial cortical support (PMCS) or neutral position (NP) type reduction was highly protective against varus collapse (p < 0.001), as well as TAD less than 25mm (p < 0.001). Additionally, the placement of screws in the central-central or central-inferior zones provided a protective effect against varus collapse (p = 0.031). Conversely, having an OTA/AO type A2.2 or A2.3 fracture significantly increased the risk of varus collapse (p = 0.030). Other factors, such as CalTAD and the nail width to medullary canal ratio, did not significantly predict varus collapse (p = 0.831 and p = 0.952, respectively). Our findings align with previous studies highlighting TAD and screw placement as critical factors in preventing fixation failure. The protective effect of PMCS or NP reduction and the increased risk associated with OTA/AO type A2.2 and A2.3 fractures are noteworthy. Unlike previous studies, CalTAD was not significantly associated with varus collapse in our cohort. The study underscores the importance of surgical technique and radiographic parameters in optimizing outcomes for elderly patients with intertrochanteric fractures. In elderly patients treated with InterTAN nails, varus collapse is influenced by fracture type, TAD, reduction quality, and screw placement. Ensuring a TAD <25mm, achieving PMCS or NP reduction, and placing screws in central-central or central-inferior zones are crucial for minimizing varus collapse. These findings highlight the importance of meticulous surgical technique and radiographic assessment in managing intertrochanteric fractures in the elderly. hip fractures, intertrochanteric fractures, internal Fixation, geriatrics, cephalomedullary nail.

Hip arthroplasty following failure of internal fixation in intertrochanteric femoral fractures: classification decision-making for femoral stem selection and clinical validation

AimsFollowing Failed Internal Fixation of Intertrochanteric Fractures (FIF-ITF), the choice of treatment remains a clinical challenge. This study introduces a novel classification system to guide the selection of femoral prostheses in hip arthroplasty (HA) and validates its clinical efficacy.MethodsRetrospectively, we analyzed 108 cases from three university-affiliated hospitals between December 2012 and February 2023 involving patients who underwent hip arthroplasty due to Failed Internal Fixation of Intertrochanteric Fractures (FIF-ITF). Patients were classified into three categories based on fracture healing, proximal femoral support, and the severity of femoral cortical defects, with subtypes identified. Surgical outcomes and complication rates were compared between the Classification-based Decision Group and the Non-classification Decision Group.ResultsThe Classification-based Decision Group did not differ significantly from the Non-classification Decision Group in operation time, blood loss, or the use of cemented stems. However, the classification system markedly reduced the risk of periprosthetic fractures intraoperatively from 22.5 to 4.4% and postoperatively from 10 to 1.4%. The Classification-based Decision Group also demonstrated higher postoperative Harris Hip Score (HHS) and Visual Analog Scale (VAS) scores.ConclusionThe proposed classification system serves as an innovative clinical tool for femoral prosthesis selection in hip arthroplasty post-FIF-ITF, effectively reducing complications and enhancing hip function in the Classification-based Decision Group, underscoring its significant clinical utility.

Lateral cortical notching for impaired healing of extra-articular proximal femur fractures (case report)

Introduction Dynamization of the nail can be used to improve osteoreparation during intramedullary interlocking nailing (IIN). The procedure can be difficult to perform in some sub- and intertrochanteric femoral fractures due to anatomical and functional features.The objective was to demonstrate a case of successful use of an original version of the lateral cortical notching (LCN) technique for dynamization of an intramedullary proximal nail in a patient with a nonunited subtrochanteric fracture.Material and methods The treatment was performed for a 66-year-old patient with a non-united intertrochanteric fracture of the right femur complicated by the breakage of an intramedullary nail. The LCN technique was successfully used to dynamize the IM nail.Results Radiological healing of the fracture and functional recovery of the patient were observed at a two-month follow-up. The absence of interfragmental compression in IIN could be caused by blocking of the sliding screw by the lateral cortical bone of the peripheral femur fragment. The complication could be prevented with LCN during primary osteosynthesis of the above fractures.Discussion Based on scientific publications and our clinical experience, we assumed that LCN can be indicated for failed healing of intertrochanteric AO/OTA 31A3.1–3 fractures, type 3 Boyd and Griffin trochanteric fractures and all types of subtrochanteric fractures as graded by Seinsheimer with a vector of interfragmental compression to be created along the femur axis during cephalomedullary osteosynthesis. The case report showed the mechanism of impaired consolidation in some intertrochanteric and subtrochanteric fractures of the femur.Conclusion The case report demonstrateed the successful use of the original version of the lateral cortical notching (LCN) technique for dynamization of an intramedullary proximal nail.

Conversion hip arthroplasty for failed nailing of intertrochanteric fracture: Reflections on some important aspects.

In this editorial, I present my comments on the article by Solarino et al. Conversion hip arthroplasty, which is an optional salvage procedure performed following unsuccessful fixation of intertrochanteric femur fractures in elderly patients, entails more complex processes and higher rates of operative complications than primary arthroplasty. Hence, it is important to consider the appropriateness of the primary treatment choice, as well as the adequacy of nailing fixation for intertrochanteric fractures. This article briefly analyzes the possible factors contributing to the nailing failure of intertrochanteric fractures and attempts to find corresponding countermeasures to prevent fixation failures. It also analyzes the choice of treatment between nailing fixation and primary arthroplasty for intertrochanteric fractures.

Functional Outcome of Intertrochanteric Fractures of the Femur Treated With Standard Surgical Modalities.

Among the most prevalent injuries among the elderly with trivial trauma are trochanteric fractures. Osteoporosis and female sex are additional risk factors. The patient's age, the fracture, their overall health, the amount of time between the fracture and treatment, the effectiveness of the treatment, any concurrent medical care, and the stability of the fixation all affect how well the patient responds to treatment. For its fixation, various implants are used. The main aim of this study is to assess the functional outcome in intertrochanteric fractures using the Harris Hip Scoring in intertrochanteric fractures. Patients presenting with intertrochanteric femur fracture were evaluated. Written consent was taken from the patient. Radiographic data were collected. Complications and varus collapse evaluated. Functional outcome was assessed with the Harris Hip Scoring system. The proportion of excellent Harris Hip Evaluation (HHE) scores was the highest in proximal femur nail(PFNA2) at six months follow-up examination, which was 11 (57.19%) more than any method. In the incidence of varus deformity, the proportion was maximum in the case of the dynamic hip screw (DHS) with three patients (33.33%), followed by PFN in 11 patients (28.95%), and the least for PFNA2 in three patients (15.79%). The mean operative time was lower in the PFN A2 group, and the HHE score values were higher than those of PFN and DHS. This study concludes that these implants have a comparable radiological and functional outcome for unstable intertrochanteric fracture except for less surgical time and blood loss in PFN A2.

Comparison of three methods of greater trochanter fixation in intertrochanteric femur fractures (AO type 31/A2) treated with cementless bipolar hemiarthroplasty

Aim: The aim of this study was to compare the three most commonly used fixation methods for the fractured trochanter major fragment in patients undergoing uncemented bipolar hemiarthroplasty for unstable intertrochanteric fractures. Methods: The medical records of 231 acute hip fracture cases aged 65 years and older with AO classification 31/A2.2 and 31/A2.3 who underwent unilateral primary cementless bipolar hemiarthroplasty at Adana Şehir Training and Research Hospital between January 2021 and January 2023 were retrospectively analyzed. The files were classified into three groups based on the fixation technique used in the operation. Results: There were 231 files, with a mean age of 82.3±7.9. The majority (55.8%) were classified as ASA III. The analysis resulted in no significant differences between the groups in terms of age, number of days between the day of the injury and the day of the surgery, fixation failure, nonunion, number of revision surgeries, hospitalization duration, and HHS recorded at the third and sixth-month follow-up visits. Among the 73 males and 158 females, the ratio of the side in which the fracture occurred showed no difference (p=0.854). The female rate was significantly higher in group 3 compared to other groups (p=0.003). Regarding union success, cases in group 1 had significantly lower trochanter major union rates (p

A Prospective Type of Study Comparing Functional and Radiological Outcome Between the Use of Long and Short Proximal Femoral Nail in Treating Patients with Intertrochanteric Femur Fractures

Objectives To assess the functional and radiological outcome of long and short PFN for treating intertrochanteric femur fractures. Material and Methods A prospective hospital-based study was conducted on 60 patients in a tertiary hospital between May 2022 and June 2023, which were randomized into Group A (patients treated with short PFN) and Group B (patients treated with long PFN) using a computer-based table of random numbers. Patients were followed up by 12 days one, three, and six months. Functional outcome was assessed in terms of Harris Hip Score (HHS), and radiological outcome was measured in terms of time of union, complications, and fracture alignment. Results The majority of patients were between 60 and 65 years old. The most common cause of the mode of injury was trivial falls (65.00%). Mean HHS score after 6, 12, 16, and 24 weeks for Group A and B was 75.96 and 76.25, 81.16 and 82.52, 84.01 and 86.23 and 88.94 and 90.11, respectively. Mostly, complication was found in Group B (16.67%) compared to Group A (13.33%). Duration of surgery was 71.4 minutes for Group A and 90.6 minutes for Group B. Mean radiological time to union for group A and B was 16.4 and 17 weeks, respectively. Conclusion PFN is a highly efficient implant, irrespective of length, used in the fixation of intertrochanteric femur fractures falling into the category of AO/OTA 31-A1.31-A2. Short PFN has an advantage in terms of decreased operative time C-arm exposure, whereas long PFN should be preferred in elderly patients due to the high chances of osteoporosis, as it splints the entire length of the diaphysis, preventing stress riser and incidence of peri-implant fracture.

Anaesthetic concerns in a patient with aortic aneurysm for non-cardiac surgery: A case report.

Abdominal aortic aneurysm poses a significant risk of rupture, with mortality rates of 80% to 90% if untreated. Management focuses on identifying and repairing the aneurysm before rupture, considering factors like size, type and symptoms. We report successful anaesthetic management in a case of intertrochanteric fracture of femur of an elderly patient who was to undergo elective surgery for abdominal aortic aneurysm. Few cases detail abdominal aortic aneurysm management during non-cardiac surgery, emphasising careful anaesthesia titration. This case report underscores the importance of precise intraoperative anaesthesia management in emergency non-cardiac surgery for abdominal aortic aneurysm patients.

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.

Standard radiographic images in cephalomedullary nailing fixation for intertrochanteric femoral fractures

To review and summarize the projections of radiographic images during cephalomedullary nailing fixation for intertrochanteric femoral fractures, and to propose a set of three projections as standard requirement in immediate postoperative fluoroscopy. Papers on intertrochanteric femoral fractures treated with cephalomedullary nailing fixation that published in a three-year period of 2021-2023 in four leading English orthopedic trauma journals were searched in PubMed. The presented radiographic pictures were identified and scrutinized as whether they were in standard anteroposterior and/or lateral projections of the implanted nails. The nonstandard presence percentage was calculated. Combined with clinical experience, the standard anteroposterior and lateral perspective images of femoral neck, the current situation of radiographic imaging in the operation of cephalomedullary nails, the literature analysis of nonstandard images, the impact of limb rotation on image interpretation, and the characteristics of anteromedial 30° oblique perspective were summarized and analyzed. The presence of nonstandard radiographic pictures is 32.1% in anteroposterior view and 69.2% in lateral view in leading orthopedic trauma journals. In cephalomedullary nailing fixation operation of intertrochanteric femoral fractures, it is reasonable to use the radiographic images of the implanted nails to represent the fractured head-neck, as the head-neck implant (lag screw or helical blade) is aimed to put into centrally in femoral head in lateral projection. Limb rotation or nonstandard projections produced distortion of images, which interfers the surgeons' judgement of fracture reduction quality and the measurement of implant position parameters in femoral head (such as neck-shaft angle and tip-apex distance), and finally lead to a meaningless comparison with the accurate normal value. The 30° anteromedial oblique view from the true lateral (set as 0°) is a tangential projection of the cortices at the anteromedial inferior corner, which gives a clear profile for the determination of cortical apposition status and mechanical support. It is essential to get firstly the true standard lateral fluoroscopy of the nail (shown as a line), then rotate the C-arm to 90° and 30° to get anteroposterior and anteromedial oblique views, and use these three immediate postoperative radiographies as the baseline for evaluation of operative quality and follow-up comparisons. As for real-time monitoring of surgical steps, intraoperative fluoroscopy follows the "Enough is Good" principle, but as for immediate postoperative data storage and basis for operative quality evaluation and baseline for follow-up comparison, it is recommended to obtain a set of three standard radiographic pictures in anteroposterior, true lateral, and 30° anteromedial oblique fluoroscopic projections.

Different surgical interventions for unstable intertrochanteric fracture of the femur: Network meta-analysis.

Although a large body of evidence has reported on surgical approaches for the treatment of unstable intertrochanteric femoral fractures, studies that comprehensively evaluate treatment outcomes are limited. The purpose of this study was to compare the effectiveness of extramedullary fixation (i.e., dynamic hip screw [DHS]), intramedullary fixation (i.e., the proximal femoral nailing [PFN]), and hemiarthroplasty (HA) for the treatment of unstable intertrochanteric femoral fractures using network meta-analysis. This study meets the preferred reporting items for systematic reviews and meta-analyses criteria. The Patient, Intervention, Comparison and Outcome search protocol framework was used to search the Google Scholar, PubMed, Embase, and Cochrane Library databases were searched from inception until June 2023. A total of 15 randomized controlled trials, including 1282 patients were analyzed. The Harris hip score (HHS) after DHS fixation was the lowest compared with that of PFN fixation and HA. DHS fixation had a significantly longer operation time than that of PFN fixation. Compared with HA, a lower incidence of superficial wound infection was observed with PFN and DHS fixations. PFN was significantly more likely to be implant cut out compared with HA. Compared with DHS, PFN and HA showed a lower incidence of fracture healing malunion. HA and PFN have good efficacy in improving the HHS and preventing joint deformities. However, HA showed a higher incidence of superficial infection than that observed with PFN, whereas a higher risk of screw cutout is observed with PFN than with HA.

A Prospective Study to Analyse the Functional and Radiological Outcome of Intertrochanteric Femur Fractures Treated with Cemented Bipolar Hemiarthroplasty

A Prospective Study to Analyse the Functional and Radiological Outcome of Intertrochanteric Femur Fractures Treated with Cemented Bipolar Hemiarthroplasty

Proximal femoral nailing for intertrochanteric fracture combined with contralateral femoral neck local osteo-enhancement procedure (LOEP) for severe osteoporotic bone loss: An original Italian case series.

Proximal femoral fractures in elderly women are a major cause of morbidity and mortality worldwide and a public health concern. Although pharmacological therapies have shown potential in improving bone mineral density (BMD) and decreasing fracture risk, the current research effort is focused on developing a procedure that can ensure both immediate and long-term efficacy. A minimally-invasive surgical approach, known as AGN1 local osteo-enhancement procedure (LOEP), has been recently developed to promote bone augmentation. The procedure implies the preparation of an enhancement site, a specific location where new bone is required within a local bony area weakened by osteoporotic bone loss, and the insertion of a triphasic, resorbable, calcium-based implant material. The results of this procedure have shown a significant and sustainable long-term increase in the proximal femur BMD and consequently in bone strength, thereby improving the femoral neck's resistance to compression and distraction forces that may result in fall-related fractures. A preliminary case series of ten women, suffering from intertrochanteric fracture and contralateral proximal femur severe osteoporotic bone loss, who underwent a combined procedure of proximal femoral nailing and AGN1 local osteo-enhancement procedure, has been developed over the course of a year of clinical and radiological data collection.

The evolution and practice on design concepts of internal fixation devices for intertrochanteric femur fractures

Surgical treatment has been established as the standard method for the treatment of intertrochanteric fractures in the elderly. The design of internal fixation devices has become the key to improve surgical outcomes and reduce postoperative complications. Centered on optimizing biomechanical performance and minimally invasive implantation, coupled with continuous material improvements, the design philosophy of internal fixation devices has also been constantly evolving. There have been several milestone advancements, such as the transition from eccentric fixation to central fixation, the adoption of sliding compression fixation, the replacement of traditional screws with spiral blades, and the shift from single to double (combination) nails. However, the incidence of internal fixation-related complications has remained at a relatively high level of 5% to 10%, without significant breakthroughs. Increasing evidence suggests that in-depth analysis of the anatomy, physiological mechanisms, and mechanical transmission characteristics of the proximal femur can help elucidate the root causes of internal fixation failures. Based on this, the proximal femoral bionic nail (PFBN) has emerged as a new design concept. By fully mimicking the anatomical, mechanical, and biological characteristics of the proximal femur, the PFBN can regulate the local mechanical environment, providing a revolutionary solution and a new approach for the treatment of proximal femoral fractures. This innovative design also has the potential to drive the paradigm shift in the treatment strategies of other fractures.

Cement Filling Technique to Prevent Greater Trochanter Displacement in Hip Arthroplasty for Femoral Intertrochanteric Fracture: A Technical Note.

With the increasing use of primary hip arthroplasty for management of intertrochanteric fractures, firm fixation and union of the greater trochanteric (GT) fragment are required during hip arthroplasty for management of intertrochanteric fractures. Various methods have been suggested to address this issue. However, displacement of the GT is a frequent occurrence. We have introduced a cement-filling technique for performance of hip arthroplasty of the proximal femur for achievement of immediate firm fixation of the GT. Cement filling during performance of hip arthroplasty for management of femoral intertrochanteric fractures is a valuable technique for preventing displacement of the GT and to encourage early mobilization.
