OBJECTIVES: To compare early outcomes of proximal femoral bionic nail (PFBN), Inter-TAN, proximal femoral nail antirotation (PFNA) for intertrochanteric fractures in elderly patients. METHODS: Eighty-two elderly patients with intertrochanteric femoral fractures treated at Xiangyang No. 1 People's Hospital affiliated with Hubei University of Medicine from December 2021 to 2022 were retrospectively analyzed. They were categorized into three surgical groups: PFBN (22 cases), Inter-TAN (20 cases), and PFNA (40 cases). Preoperative demographics and fracture characteristics were compared, alongside intraoperative and postoperative metrics like operative time and complication rates. RESULTS: In the PFBN group, operative time, fluoroscopy use, blood loss, and transfusion were higher, but postoperative weight-bearing, healing, and hospital stay were shorter compared to the Inter-TAN and PFNA groups (P<0.05). Inter-TAN had a significantly shorter postoperative weight-bearing time than PFNA (P<0.001). Other compared factors showed no significant differences between groups (P>0.05), including complication rates and scores at 6-month follow-up. CONCLUSIONS: PFBN, a novel surgical approach for intertrochanteric fractures in elderly patients, outperforms Inter-TAN and PFNA by accelerating early weight-bearing and hastening fracture recovery.

Several challenges exist for the foot and ankle surgeon when addressing the complications associated with ankle fracture repair. The risk of joint destruction, debilitation, and even limb loss may be amplified by the noncompliant patient. There is an abundance of literature documenting the management of fracture nonunions in the setting of infection with a variety of techniques proven successful in managing large osseous defects and eradicating infection. We present a particularly challenging case in which we modified an existing method of treatment to preserve the ankle joint of a failed reduction complicated by septic nonunion following placement of a fibular intramedullary nail.

Introduction: Bone marrow embolization may complicate orthopedic surgery, potentially causing fat embolism syndrome. The inflammatory potential of bone marrow emboli is unclear. We aimed to investigate the inflammatory response to femoral intramedullary nailing, specifically the systemic inflammatory effects in plasma, and local tissue responses. Additionally, the plasma response was compared to that following intravenous injection of autologous bone marrow. Methods: Twelve pigs underwent femoral nailing (previously shown to have fat emboli in lung and heart), four received intravenous bone marrow, and four served as sham controls. Blood samples were collected hourly and tissue samples postmortem. Additionally, we incubated bone marrow and blood, separately and in combination, from six pigs in vitro. Complement activation was detected by C3a and the terminal C5b-9 complement complex (TCC), and the cytokines TNF, IL-1ß, IL-6 and IL-10 as well as the thrombin-antithrombin complexes (TAT) were all measured using enzyme-immunoassays. Results: After nailing, plasma IL-6 rose 21-fold, compared to a 4-fold rise in sham (p=0.0004). No plasma differences in the rest of the inflammatory markers were noted across groups. However, nailing yielded 2-3-times higher C3a, TCC, TNF, IL-1ß and IL-10 in lung tissue compared to sham (p<0.0001-0.03). Similarly, heart tissue exhibited 2-times higher TCC and IL-1ß compared to sham (p<0.0001-0.03). Intravenous bone marrow yielded 8-times higher TAT than sham at 30 minutes (p<0.0001). In vitro, incubation of bone marrow for four hours resulted in 95-times higher IL-6 compared to whole blood (p=0.03). Discussion: A selective increase in plasma IL-6 was observed following femoral nailing, whereas lung and heart tissues revealed a broad local inflammatory response not reflected systemically. In vitro experiments may imply bone marrow to be the primary IL-6 source.

The effect of circumference and displacement of the third fracture fragment on fracture healing after intramedullary nailing of femoral shaft fractures with a third fracture fragment was investigated. A retrospective cohort study was conducted to analyze the data of 142 patients who suffered femoral shaft fractures with a third fracture fragment and were admitted to the First People's Hospital of Lianyungang from February 2016 to December 2021. According to the circumference of the third fracture fragments, these were divided into three types of type 1: 71 cases; type 2: 52 cases; and type 3: 19 cases. On the basis of the diaphyseal diameter, the degree of displacement of the third fracture fragment was classified into three degrees of degree I: 95 cases; degree II: 31 cases; and degree III: 16 cases. Postoperative follow-up was performed to compare the fracture healing rate, healing time, and the modified Radiographic Union Scale for Tibia (mRUST) at 9th month after surgery in each group. All 142 patients were followed up after operation, with an average of (14.7 ± 4.1) months, and the overall healing rate was 73.4%. When the third fracture fragments were displaced in degree II and III, the mRUST score at 9th month in the type 1 group was higher than that in the type 2 and 3 groups (P = 0.017). Logistic regression analysis showed that greater displacement of third fracture fragments and greater circumference were associated with lower fracture healing rates (P < 0.05). After intramedullary nailing of femoral fractures, the degree of third fragment displacement and circumference affect fracture healing, and the former has a greater impact. When the third fracture fragment is displaced to degree II or III and its circumference is type 2 or type 3, it significantly affects the fracture healing. Intraoperative intervention to reduce the distance of third displacement of the fragment is required to reduce the incidence of non-union.

The proximal femoral fracture patients in particular fractures in the trochanteric region of the femur could have treatment under the title proximal femoral nailing (PFN)-this operation is a less invasive type. The proximal femoral nail, an osteosynthetic implant, has been investigated to produce positive heeling to ensure a better fixation, several advantages of PFN include such as bleeding time during operation which leads to the need to perform reaming on the femoral canal during surgery. MATERIAL AND METHODS: The study was carried out at three teaching Hospitals in Mosul City from the period of January 2022 to December 2022, fourteen nurses from orthopaedic wards were subjected to this study, all the nurses were evaluated by the checklist, and they attended the training program which was taken from the Iraqi Ministry of Health guide for organizing nursing operations and practices inside the hospitals and medical departments. RESULTS AND DISCUSSION: More than (50%) of the study sample had a poor score in the initial evaluation for post-operative steps and after submitting the training program, the performance and practices of the nursing staff have improved significantly where the poor score decreased to approximately (25%) at P value (0.0001). CONCLUSION: The study concluded that there is a significant and clear weakness in the performance and practices of the nursing staff towards patients with upper femoral fractures in the fracture wards and that the training program that was given to them improved their performance and practices significantly and effectively.

OBJECTIVE: To explore the effect of collaborative nursing based on Roy Adaptive Mode (RAM) on postoperative functional reconstruction, soft tissue pain and quality of life in patients with femoral intertrochanteric fracture. METHODS: A retrospective matched control method was used in this study. A total of 96 patients with femoral intertrochanteric fracture admitted to our hospital from July 2018 to September 2021 were selected. According to different nursing methods, the patients were divided into a collaborative group and a routine group, with 48 cases in each group. Patients in both groups were treated with intramedullary nail surgery. The routine group was given routine perioperative nursing intervention, and the collaborative group was given collaborative nursing intervention on this basis. The hip function recovery and quality of life before and after the intervention were compared between the two groups. The preoperative and postoperative pain degree, and the perioperative complications of the two groups were recorded. Logistic multivariate regression analysis was used to analyze the risk factors affecting the recovery of hip joint function in patients with femoral intertrochanteric fracture after operation, thereby constructing a risk prediction model. ROC curve was used to analyze the clinical value of influencing factors in predicting postoperative hip function recovery in patients with femoral intertrochanteric fracture. RESULTS: Harris score each dimension after intervention in the collaborative group was obviously higher than that of before intervention and the conventional group (P < 0.05). After intervention, the excellent and good rate of hip joint function the collaborative group was 83.33%, which was significantly higher than 60.42% in the routine group (P < 0.05). Postoperative VAS scores each time point in the collaborative group was obviously lower than that in the routine group (P < 0.05). After intervention, the scores of physiological function, physiological role, body pain and general health in the collaborative group were significantly higher than those in the routine group (P < 0.05). The incidence of complications in the collaborative group was 6.25%, which was significantly lower than 22.92% in the routine group (P < 0.05). There were statistically significant differences in age, preoperative ASA grade, internal fixation method, osteoporosis grade and perioperative nursing methods between the excellent hip recovery group and the poor hip recovery group (P < 0.05). Logistic multivariate regression analysis showed that age, preoperative ASA grade, internal fixation method and osteoporosis grade were the risk factors affecting the recovery of hip joint function after operation, and perioperative nursing method was the protective factor (P < 0.05). Among the influencing factors, the internal fixation method and the grade of osteoporosis had certain clinical value in predicting the recovery of hip joint function in patients with femoral intertrochanteric fracture after operation. CONCLUSION: The RAM model-based collaborative nursing method may effectively restore the hip joint function of patients with femoral intertrochanteric fracture after operation, and may reduce the perioperative pain degree of patients, improve the quality of life of patients and reduce the incidence of complications, which can be popularized and applied in clinical practice. In addition, there are many factors influencing the recovery of hip joint function in patients with femoral intertrochanteric fracture after operation, and targeted measures should be taken according to the influencing factors to improve the effect of intramedullary nail treatment.

PURPOSE: Malalignment of distal tibia fractures can lead to malunion/nonunion or alter the limb mechanical axis which may cause arthritis. Proposed methods to decrease malalignment include fibular fixation or multiplanar interlocking screws, however these remain controversial. This study aimed to identify factors associated with malalignment in distal tibial fractures with associated fibular shaft fractures. METHODS: A retrospective review was performed of distal tibia fractures with associated fibular shaft fractures treated with intramedullary nailing at two level one trauma centers between 2015 and 2019. Cases involving malalignment (> 5° of deviation from anatomic axis on either coronal/sagittal axis) on final follow-up (minimum three months postoperatively) were compared to those without malalignment with regard to demographics, fracture characteristics, intraoperative characteristics, and complications. RESULTS: The rate of malalignment was 13%. On multivariate analysis, multiplanar distal interlocking screw fixation (odds ratio [OR], 0.18; 95% confidence interval [CI] 0.03-0.92) was associated with a decreased rate of final malalignment, while nail diameter > 10 mm was associated with a higher rate (OR, 4.05; 95% CI 1.25-13.11). Fibular fixation was not associated with malalignment. CONCLUSION: Multiplanar distal interlocking screws may protect against malalignment. Fibula fixation does not appear associated with a decreased rate of malalignment in distal tibia fractures treated with intramedullary nails. LEVEL OF EVIDENCE: III.

In elastic stable intramedullary nailing (ESIN), there are different opinions among surgeons on whether to leave the nail buried in the same arm or to leave it exposed. OBJECTIVE: To determine the risk of re-fracture in patients with a nail buried directly into the amr or left exposed as a treatment for forearm fractures, and to investigate postoperative complications. PATIENTS AND METHOD: The study included 113 pediatric patients with a forearm fracture of both diaphyses. Two groups were formed according to whether the nail was buried (Group B, n: 53) in the same arm or left exposed (Group E, n: 60). Data on the number of open reductions, the time to nail removal, the anesthesia type used for its removal, the number of re-fractures, skin infection, and nail entry site irritation were analyzed. RESULTS: The mean union times between the groups were not significantly different (P = 0.371). The mean time of nail removal in group B (16.02 ± 1.29 weeks) was significantly longer than that of group E (6.65 ± 0.95 weeks) (P < 0.001). Open reduction rates were similar between groups (P = 0.401). The general anesthesia rate for nail removal in group B (77.4%) was significantly higher than group E (11.7%) (P < 0.001). The re-fracture rate was higher in patients who underwent open reduction in both groups (P < 0.001). CONCLUSION: The results of this study demonstrated that, despite the increased infection rate, leaving the nail exposed did not increase the re-fracture rate, which was associated with open reduction.

BACKGROUND: Although segmental femoral shaft fractures (SFSF) are very challenging to manage, there has been no critical evaluation of the current practices and outcomes. The aim of this study is to evaluate their characteristics, management trends, outcomes, and complications. METHODS: A literature search was conducted via the SCOPUS, Embase (via SCOPUS) and MEDLINE (via PubMed) between 1995 and 2023. Studies were included if they reported patient demographics, mechanism of injury, classification of fractures, associated injuries, type of management, outcomes, and complications. EXCLUSION CRITERIA: only diaphyseal fractures were included and proximal and distal femoral fractures were excluded from this study. RESULTS: Overall, 22 studies met the inclusion criteria reporting on 313 patients. Mean age was 36.2 years with male-female ratio of 4.8 to 1. The majority were high-energy fractures secondary to road traffic accidents and 16% were open. The most commonly associated injuries included chest injury (27%) and lower leg fractures (24%). Treatment consisted of intramedullary nailing (IMN) (72%), plating (22%) or both combined (6%). Outcomes reported: good in 70%, fair in 10%, excellent in 19% and poor in 2% of cases. Mean time to union was 20 weeks. Complications are reported in 24% of cases, with most common delayed union (5%) and non-union (4%). CONCLUSION: SFSF are high-energy fractures occurring most commonly in young males, are open in 16% of cases and have significant associated injuries. In their overwhelming majority, IMN is the mainstay of treatment. The expected outcome is generally good in 70% of cases, although not devoid of complications in 24% of cases and patients must be aware of this during the consent process.

BACKGROUND: The treatment of the displaced proximal humerus fractures (PHF) still facing a lot of unsolved problems. The aim of this study was to evaluate the clinical effect of MultiLoc nails for the treatment of PHF and present outcomes of patients with different Neer's classification and reduction quality. METHODS: Adult patients with PHFs were recruited and treated with MultiLoc nail. Intraoperative data, radiographic and functional outcomes, as well as occurrence of postoperative complications were assessed. RESULTS: 48 patients met inclusion and exclusion criteria and were included in this study. The DASH Score were 32.2 ± 3.1 points at 12 months, and 37.3 ± 2.5 points at the final follow-up. The mean ASES score at 12 months and final follow-up were 74.4 ± 6.2 and 78.8 ± 5.1, respectively. The mean CM Score in all 48 patients reached 68 ± 6.4 points at the final follow-up, relative side related CM Score 75.2 ± 7.7% of contralateral extremity. The incidence rate of complications was 20.8%. Patients with fracture mal-union, adhesive capsulitis were observed but no secondary surgeries were performed. There was no significantly difference of DASH Score 12 months after surgery and at the last follow-up among patients with different Neer's classification or reduction quality. However, functional outcomes such as ASES score and CM score were significantly influenced by severity of fracture and the quality of fracture reduction. CONCLUSIONS: Our study demonstrated that MultiLoc nails is well suited for proximal humeral fractures, with satisfactory health status recovery, good radiographic results, positive clinical outcomes and low rates of complications. The treatment for four part PHF still faces great challenges. Accurate fracture reduction was an important factor for good functional result.

BACKGROUND: The rotational change after using a flexible intramedullary (IM) nail for femoral shaft fractures has been a concern for many surgeons. Recently, a statistical shape model (SSM) was developed for the three-dimensional reconstruction of the femur from two-dimensional plain radiographs. In this study, we measured postoperative femoral anteversion (FAV) in patients diagnosed with femoral shaft fractures who were treated with flexible IM nails and investigated age-related changes in FAV using the SSM. METHODS: This study used radiographic data collected from six regional tertiary centers specializing in pediatric trauma in South Korea. Patients diagnosed with femoral shaft fractures between September 2002 and June 2020 and patients aged < 18 years with at least two anteroposterior (AP) and lateral (LAT) femur plain radiographs obtained at least three months apart were included. A linear mixed model (LMM) was used for statistical analysis. RESULTS: Overall, 72 patients were included in the study. The average patient age was 7.6 years and the average follow-up duration was 6.8 years. The average FAV of immediate postoperative images was 27.5 ± 11.5°. Out of 72 patients, 52 patients (72.2%) showed immediate postoperative FAV greater than 20°. The average FAV in patients with initial FAV > 20° was 32.74°, and the LMM showed that FAV decreased by 2.5° (p = 0.0001) with each 1-year increase from the time of initial trauma. CONCLUSIONS: This study explored changes in FAV after femoral shaft fracture using a newly developed technology that allows 3D reconstruction from uncalibrated 2D images. There was a pattern of change on the rotation of the femur after initial fixation, with a 2.5° decrease of FAV per year.

OBJECTIVES: To compare the iatrogenic radial nerve injury (iRNI) rate of different implant (plate vs. intramedullary nail) and surgical approaches during humeral shaft fracture surgery. METHODS: The online PubMed database was used to search for articles describing iRNI after humeral fracture with a publication date from Jan 2000 to October 2023. The following types of articles were selected: (1) case series associating with adult humeral shaft fracture, preoperative radial nerve continuity, non-pathological fracture and non-periprosthetic fracture; (2) involving humeral shaft (OTA/AO 12) fractures. Articles where we were unable to judge surgical approach or fracture pattern (OTA/AO 12) were excluded. The data were analyzed by SPSS 27.0 and Chi-square test was performed to identify incidence of iRNI associated with different implant and surgical approaches. RESULTS: Fifty-four articles with 5063 cases were included, with 3510 cases of the plate, 830 cases of intramedullary nail and 723 cases of uncertain internal fixation. The incidences of iRNI with plate and intramedullary nail were 5.95% (209/3510) and 2.77% (23/830) (p < 0.05). And iRNI incidences of different surgical approaches were 3.7% (3/82) for deltopectoral approach, 5.74% (76/1323) for anterolateral approach, 13.54% (26/192) for lateral approach and 6.68% (50/749) for posterior approach. The iRNI rates were 0.00% (0/33) for anteromedial MIPO, 2.67% (10/374) for anterolateral MIPO and 5.40% (2/37) for posterior MIPO (p > 0.05). The iRNI rates were 2.87% (21/732) for anterograde intramedullary nail and 2.04% (2/98) for retrograde intramedullary nail (p > 0.05). In humeral bone nonunion surgery, the rate of iRNI was 15.00% (9/60) for anterolateral approach, 16.7% (2/12) for lateral approach and 18.2% (6/33) for posterior approach (p > 0.05). CONCLUSION: Intramedullary nailing is the preferred method of internal fixation for humeral shaft fractures that has the lowest rate of iRNI. Compared with anterolateral and posterior approaches, the lateral surgical approach had a higher incidence of iRNI. The rate of iRNI in MIPO was lower than that in open reduction and internal fixation. LEVEL OF EVIDENCE: Level IV.

BACKGROUND: Post-operative non-compliance is a risk factor for fracture fixation failure and presents a challenge for revision surgery planning. We present a patient who underwent revision surgery for a proximal humerus fracture with lateral locked plating augmented with a UV light activated intramedullary implant. CASE: A 45-year-old woman with a history of alcoholism presented with a proximal humerus fracture. After undergoing open reduction internal fixation with a lateral locking plate, the patient suffered a fall secondary to delirium tremens. New radiographs demonstrated displacement of the fracture with failure of screws. Revision surgery consisting of removal of the initial construct as well as open reduction internal fixation via lateral locking plate, augmented with a UV-activated intramedullary cement implant, was performed. CONCLUSION: This is the first case report describing the use of a UV-activated intramedullary cement implant to augment the use of lateral locked plating for proximal humerus fractures. This case illustrates the successful management using UV-activated intramedullary cement to augment fixation, specifically in a patient with risk factors and post-operative non-compliance that predispose to fixation failure.

PURPOSE: To describe the methods and outcomes of reamed intramedullary nailing (IMN) of diaphyseal multifragmentary femur (AO/OTA C2 and C3) fractures (DMFFs) in a low-resource setting without fluoroscopy and fracture table. METHODS: The prospective study involved 35 DMFFs among 318 femur fractures treated ≤ 3 weeks post-injury with SIGN nails. The fractures were fixed without fluoroscopy, fracture table and power reaming. Closed, mini-open or open reduction was done. Anatomical length and alignment were ensured using a surgical support triangle during retrograde nailing, and by an assistant during antegrade nailing. Follow-ups were done at 6 weeks, 12 weeks and 6 months. RESULTS: DMFFs constituted 11.0% of the 318 fractures. Twenty-four (68.6%) were males. The mean age was 39.0 years (range 17-75 years). About 94.3% were injured in road traffic accidents. Fracture reduction was closed in 18, mini-open in 8 and full-open in 9. The operative times were significantly shorter for closed than open reduction (p = 0.001). Five fractures received a supplemental fixation with plate or lag screws. By the 12th post-operative week, 97.1% demonstrated continuing radiographic healing, 94.1% tolerated painless weight-bearing and 91.2% could squat & smile. There was no infection or noticeable rotational malunion. Five fractures healed with a limb-length discrepancy of < 2 cm. CONCLUSION: The study demonstrates the feasibility of reamed IMN of DMFFs without fluoroscopy. The outcomes were satisfactory. Although the small sample size and short follow-up period are limitations, the study could serve as a basis for future larger studies in low-resource settings.

PURPOSE: Surgical intervention for lateral compression (LC) 1 and 2 pelvic ring fractures is controversial. Posterior ring stabilization remains the most common mode of initial fixation. However, greater mechanical instability is observed in the anterior component of LC pelvic fractures. This study tested whether reduction and percutaneous superior ramus fixation will decrease the instability of LC pelvic fractures on intraoperative fluoroscopic imaging. METHODS: All adult patients (≥ 18 years) presenting with either a Young-Burgess LC1 or LC2 pelvic ring disruption treated operatively with percutaneous anterior followed by posterior fixation by a single surgeon from July 2021 to June 2023 were retrospectively reviewed. Displacement of the anterior ring to intraoperative manual internal rotation stress examination under fluoroscopy was compared before and after anterior pelvic ring reduction and fixation and prior to posterior pelvic ring fixation. Pre- and post-operative visual analog scores (VAS) for pain were also compared. RESULTS: Twenty-one patients with a mean age of 48.7 years were included. Fifteen patients (71.4%) presented with an LC1, and six (28.6%) with an LC2 injury patterns. Anterior pelvic fixation alone provided 7.5mm reduction in mean displacement of the anterior pelvic ring (pre-operative = 9.2 mm vs. post-operative = 1.6 mm, p < 0.001). VAS significantly decreased from 7.2 one-day pre-operatively to 2.2 twenty-four h post-operatively (p < 0.001). CONCLUSIONS: Reduction and fixation of the anterior pelvic ring prior to posterior fixation for LC1 and LC2 pelvic ring disruptions substantially improves mechanical stability on intraoperative stress examination. Combination of percutaneous anterior and posterior fixation significantly decreased VAS above the MCID 24 h after stabilization.

BACKGROUND: Osteosynthesis using antegrade intramedullary nailing for humeral shaft fractures yields satisfactory bone union rates; however, it may adversely affect postoperative shoulder function. To date, factors affecting mid- or long-term shoulder functional outcomes following intramedullary nail fixation have not been clarified. In this study, we aimed to identify the risk factors for poor mid-term functional outcomes over 5 years postoperatively following antegrade intramedullary nail osteosynthesis for humeral shaft fractures. METHODS: We retrospectively identified 33 patients who underwent surgery using an antegrade intramedullary nail for acute traumatic humeral shaft fractures and were followed up for at least 5 years postoperatively. We divided the patients into clinical failure and no clinical failure groups using an age- and sex-adjusted Constant score of 55 at the final follow-up as the cutoff value. We compared preoperative, perioperative, and postoperative factors between the two groups. RESULTS: Five of the 33 patients had poor shoulder functional outcomes (adjusted Constant score < 55) at a mean follow-up of 7.5 years postoperatively. Proximal protrusion of the nail at the time of bone union (P = 0.004) and older age (P = 0.009) were significantly associated with clinical failure in the univariate analyses. Multivariate analysis showed that proximal protrusion of the nail (P = 0.031) was a risk factor for poor outcomes. CONCLUSIONS: The findings of this study provide new information on predictive factors affecting mid-term outcomes following osteosynthesis using antegrade nails. Our results demonstrated that proximal protrusion of the nail was significantly associated with poor mid-term functional shoulder outcomes. Therefore, particularly in older adults, it is essential to place the proximal end of the intramedullary nail below the level of the articular cartilage.

BACKGROUND: Femoral head varus triggers poor clinical prognosis in intertrochanteric fracture patients with proximal femoral nail antirotation (PFNA) fixation. Studies present that changes in nail position and screw insertion angles will affect fixation stability, but the biomechanical significance of these factors on the risk of femoral head varus has yet to be identified in PFNA fixed patients. METHODS: Clinical data in PFNA fixed intertrochanteric fracture patients have been reviewed, the relative position of intermedullary nail has been judged in the instant postoperative lateral radiography. Regression analyses have been performed to identify the effect of this factor on femoral head varus. Corresponding biomechanical mechanism has been identified by numerical mechanical simulations. RESULTS: A clinical review revealed that ventral side nail insertion can trigger higher risk of femoral head varus, corresponding numerical mechanical simulations also recorded poor fixation stability in models with ventral side nail insertion, and changes in the trajectory of anti-rotation blade will not obviously affect this tendency. CONCLUSIONS: Ventral side insertion of intramedullary nail can trigger higher risk of femoral head varus in PFNA fixed patients by deteriorating the instant postoperative biomechanical environment, and changes in blade trajectory cannot change this tendency biomechanically. Therefore, this nail position should be adjusted to optimize patients' prognosis.

Background: The objective of this study was to investigate the incidence of osteonecrosis of the femoral head (ONFH) after cephalomedullary nailing in elderly patients with pertrochanteric fractures and to analyze the risk factors related to ONFH. Methods: A total of 689 consecutive patients with cephalomedullary nailing for pertrochanteric fractures at our hospital were recruited. Of these, 368 patients who met the inclusion criteria were finally enrolled. ONFH after cephalomedullary nailing was identified by reviewing patients' electronic charts and serial radiographs. The ONFH group was then compared with the non-ONFH group. Results: ONFH was identified in 9 of 368 patients (2.4%). The time to diagnosis of ONFH averaged 23.8 months (range, 5-54 months) after index surgery. The mean age, body mass index, and bone mineral density (T-score in femur neck) were 84.1 ± 7.1 years, 23.7 ± 3.6 kg/m2, and -3.1 ± 0.7 kg/m2, respectively. The times from injury to surgery, from admission to surgery, and operation time averaged 4.2 ± 2.7 days, 3.6 ± 2.6 days, and 87.2 ± 30.0 minutes, respectively. Among 9 patients, 3 underwent conversion arthroplasty. The ONFH group had advanced age (p = 0.029), more basicervical fracture components (p = 0.002), and inadequate reduction (p = 0.045) compared to the non-ONFH group. On multivariate analysis, advanced age (odds ratio [OR], 1.61;, p = 0.022), basicervical fracture components (OR, 24.58; p = 0.001), and inadequate reduction (OR, 4.11; p = 0.039) were identified as risk factors of ONFH. Conclusions: Although ONFH is relatively rare after cephalomedullary nailing for pertrochanteric fractures in elderly patients, its risk may increase with advanced age, basicervical fracture components, and inadequate reduction. Therefore, in patients with these risk factors, meticulous and longer follow-up is needed even after bone union.

BACKGROUND This prospective study from a single center aimed to compare the perioperative blood loss (PBL) in 79 patients with intertrochanteric fractures (IF) treated with intramedullary nailing (IMN) using 3 regimens of combined tranexamic acid (TXA) and low molecular weight heparin (LMWH), proposing a novel therapy of 4-dose TXA. MATERIAL AND METHODS We recruited 79 patients and randomly divided them into 3 groups. The 4-dose TXA group (22 patients) received 1.0 g intravenous TXA 30 min before surgery and 1.0 g at intervals of 3, 6, and 9 h before surgery. The 1-dose TXA group (25 patients) received 1.0 g intravenous TXA 30 min before surgery, while the control group (32 patients) did not receive TXA. LMWH was applied 12 h after surgery in each group. The primary metrics evaluated included hidden blood loss (HBL), total blood loss (TBL), and the number and incidence rate of deep vein thrombosis (DVT). RESULTS Analysis of the HBL revealed that the 4-dose TXA group had the lowest average (583.13±318.08 ml), followed by the 1-dose TXA group (902.94±509.99 ml), and the control group showed the highest (1154.39±452.06 ml) (P<0.05). A similar result was observed for TBL (4-dose group: 640.86±337.22 ml, 1-dose group: 971.74±511.14 ml, control group: 1226.27±458.22 ml, P<0.05). Regarding DVT, the 4-dose TXA group had 5 cases (incidence rate 22.73%), the 1-dose TXA group had 6 cases (incidence rate 24.00%), and the control group had 8 cases (incidence rate 25.00%), with no significant difference among groups (P>0.05). CONCLUSIONS Treatment using 4-dose TXA and LMWH can effectively reduce PBL without increasing the DVT risk in IF patients with IMN.
