OBJECTIVE: To explore effectiveness of positive support reduction and internal fixation in the treatment of femoral neck fractures. METHODS: A clinical data of 74 patients with femoral neck fractures treated with hollow screw internal fixation between September 2017 and September 2021 was retrospectively analyzed. Based on the quality of fracture reduction, they were divided into positive support reduction group (group A, n=25), negative support reduction group (group B, n=21), and anatomical reduction group (group C, n=28). There was no significant difference in baseline data such as gender, age, cause of injury, disease duration, fracture side, Garden classification, and fracture line position classification between groups (P>0.05). The occurrence of complications such as early fixation failure, femoral neck shortening, non-union of fractures, and femoral head necrosis in three groups, as well as the Harris score of the hip joint were recorded and compared. RESULTS: All patients had primary healing of incisions after operation and were followed up more than 12 months. The follow-up time for groups A, B, and C was (21.1±5.7), (22.6±4.3), and (21.9±4.1) months, respectively; there was no significant difference between groups (P>0.05). There was no significant difference in the incidences of non-union of fractures, early internal fixation failure, and the femoral head necrosis between groups (P>0.05). The incidence and length of femoral neck shortening, and the hip Harris score at last follow-up in groups A and C were all superior to those in the group B, with significant difference (P<0.05). There was no significant difference in the above indicators between groups A and C (P>0.05). CONCLUSION Positive support reduction can provide a good biomechanical environment for the healing of femoral neck fractures, thereby achieving a higher fracture healing rate, reducing the occurrence of femoral neck shortening, minimizing the function of hip joint, and achieving effectiveness similar to anatomical reduction.

OBJECTIVE: To summarize the research progress on the evaluation methods of head-neck nail positions in femoral intertrochanteric fractures. METHODS: The literature about the evaluation methods of head-neck nail positions for femoral intertrochanteric fractures in recent years was extensively reviewed, and research progress in the aspects of evaluation methods, clinical applications, and limitations were summarized. RESULTS: The position of head-neck nails in femoral intertrochanteric fractures is closely related to postoperative complications of head-neck nail cutting. Currently, the tip-apex distance (TAD) and femoral head zoning are widely used to evaluate the position of head-neck nails. The main opinion in the literature is that the use of TAD and femoral head zoning can effectively reduce the incidence of head-neck nails cutting. Parker's ratio, as one of the evaluation methods, has been controversial in subsequent studies and has not been widely used in clinical practice. The TAD as referenced to the calcar (CalTAD), which was modified based on TAD, has been gradually accepted by the clinic, but whether it is better than the TAD has not yet been conclusively determined. In recent years, new evaluation methods have been proposed to supplement the previous evaluation methods, such as the tip-neck distance ratio (TNDR) and the standardized TAD (STAD) to avoid the limitations of the TAD and the CalTAD by the volume of the femoral head, and the axis-blade angle (ABA) to supplement the direction of the head-neck nails channel, but at present the clinical application is relatively underutilized, and the validity of the method needs to be further verified. CONCLUSION Currently, there are many methods for evaluating the position of head-neck nails in femoral intertrochanteric fractures, TAD<25 mm combined with head-neck nails placed in the middle-middle quadrant or lower-middle quadrant of the femoral head division is currently a highly recognized assessment in the literature, but the optimal assessment is still controversial, and further research needs to be studied.

OBJECTIVE: To compare the effectiveness of lower extremity axial distractor (LEAD) and traction table assisted closed reduction and intramedullary nail fixation in treatment of femoral subtrochanteric fracture. METHODS: The clinical data of 117 patients with subtrochanteric fracture of femur treated by closed reduction and intramedullary nail fixation between May 2012 and May 2022 who met the selection criteria were retrospectively analyzed. According to the auxiliary reduction tools used during operation, the patients were divided into LEAD group (62 cases with LEAD reduction) and traction table group (55 cases with traction table reduction). There was no significant difference in baseline data, such as gender, age, injured side, cause of injury, fracture Seinsheimer classification, time from injury to operation, and preoperative visual analogue scale (VAS) score, between the two groups ( P>0.05). Total incision length, operation time, intraoperative blood loss, fluoroscopy frequency, closed reduction rate, fracture reduction quality, fracture healing time, weight-bearing activity time, and incidence of complications, as well as hip flexion and extension range of motion (ROM), Harris score, and VAS score at 1 month and 6 months after operation and last follow-up were recorded and compared between the two groups. RESULTS: There were 14 cases in the LEAD group from closed reduction to limited open reduction, and 43 cases in the traction table group. The incisions in the LEAD group healed by first intention, and no complication such as nerve and vascular injury occurred during operation. In the traction table group, 3 cases had perineal crush injury, which recovered spontaneously in 1 week. The total incision length, operation time, intraoperative blood loss, fluoroscopy frequency, and closed reduction rate in the LEAD group were significantly better than those in the traction table group ( P<0.05). There was no significant difference in the quality of fracture reduction between the two groups ( P>0.05). Patients in both groups were followed up 12-44 months, with an average of 15.8 months. In the LEAD group, 1 patient had delayed fracture union at 6 months after operation, 1 patient had nonunion at 3 years after operation, and 1 patient had incision sinus pus flow at 10 months after operation. In the traction table group, there was 1 patient with fracture nonunion at 15 months after operation. X-ray films of the other patients in the two groups showed that the internal fixator was fixed firmly without loosening and the fractures healed. There was no significant difference in fracture healing time, weight bearing activity time, incidence of complications, and postoperative hip flexion and extension ROM, Harris score, and VAS score at different time points between the two groups ( P>0.05). CONCLUSION For femoral subtrochanteric fracture treated by close reduction and intramedullary nail fixation, compared with traction table, LEAD assisted fracture reduction can significantly shorten the operation time, reduce intraoperative blood loss and fluoroscopy frequency, reduce incision length, effectively improve the success rate of closed reduction, and avoid complications related to traction table reduction. It provides a new method for good reduction of femoral subtrochanteric fracture.

OBJECTIVE: To investigate the early effectiveness of the Ti-Robot assisted femoral neck system (FNS) in the treatment of elderly Garden type Ⅱ and Ⅲ femoral neck fractures. METHODS: A retrospective analysis was conducted on the clinical data of 41 elderly patients with Garden type Ⅱ and Ⅲ femoral neck fractures who were admitted between December 2019 and August 2022 and met the selection criteria. Among them, 21 cases were treated with Ti-Robot assisted FNS internal fixation (study group), and 20 cases were treated solely with FNS internal fixation (control group). There was no significant difference in baseline data, including gender, age, side, cause of injury, time from injury to surgery, fracture Garden classification, and fracture line classification, between the two groups ( P>0.05). Surgical effectiveness was evaluated based on parameters such as operation time (including incision time and total operation time), reduction level, number of dominant pin insertions, intraoperative fluoroscopy frequency, incision length, whether to extend the incision, need for assisted reduction, postoperative hospital stay, fracture healing time, incidence of osteonecrosis of the femoral head, postoperative visual analogue scale (VAS) score at 1 day, and Harris hip score at last follow-up. RESULTS: The study group showed significantly shorter incision time, fewer dominant pin insertions, fewer instances of extended incisions, fewer intraoperative fluoroscopy frequency, and smaller incisions than the control group ( P<0.05). There was no significant difference in total operation time, reduction level, and assisted reduction frequency between the two groups ( P>0.05). Both groups achieved primary wound healing postoperatively, with no complications such as incision leakage or skin infection. All patients were followed up 12-24 months with an average of 14.6 months. Fractures healed in both groups, with no significant difference in healing time ( P>0.05). There was no significant difference in postoperative hospital stay between the two groups ( P>0.05). The study group showed significantly better VAS score at 1 day after operation and Harris hip score at last follow-up when compared to the control group ( P<0.05). No complication such as internal fixation failure, fracture displacement, or hip joint varus occurred in both groups during the follow-up. Osteonecrosis of the femoral head occurred in 1 patient of the control group, while no was observed in the study group, and the difference in the incidence of osteonecrosis of the femoral head between the two groups was not significant ( P=0.488). CONCLUSION Compared to sole FNS internal fixation treatment, Ti-Robot assisted FNS internal fixation for elderly Garden typeⅡ and Ⅲ femoral neck fractures can reduce incision time, achieve minimally invasive and accurate nail implantation, and decrease intraoperative fluoroscopy frequency, leading to improved postoperative hip joint function recovery.

OBJECTIVE: To compare and analyze the early clinical effect of direct superior approach(DSA) and posterior lateral approach (PLA) in hemiarthroplasty for elderly patients with femoral neck fracture. METHODS: The clinical data of 72 elderly patients with femoral neck fracture who underwent hemiarthroplasty from January 2020 to December 2021 were retrospectively analyzed. Among them, 36 patients were operated through minimally invasive DSA including 10 males and 26 females with an average age of (82.82±4.05) years old; the other 36 patients underwent traditional PLA including 14 males and 22 females with an average age of (82.79±3.21) years old. The perioperative related indexes and Harris scores during follow-up between two groups were compared. RESULTS: Comparison of operation time between two groups, (79.41±17.39) min of DSA group was shorter than(98.45±26.58) min of PLA group;incision length (8.33±2.69) cm was shorter than (11.18±1.33) cm of PLA group;intraoperative blood loss (138.46±71.58) ml was less than (173.51±87.17) ml of PLA group, initial landing time (3.04±0.95) d was earlier than (4.52±1.10) d of PLA group, hospitalization time (8.70±1.89) d was shorter than (10.67±2.35) d of PLA group(P<0.05). There was no statistical difference in Harris score between two groups before operation(P>0.05), but Harris score in DSA group was higher than that of PLA group at 1 month after operation(P<0.05), but at 12 months after operation, the difference was not statistically significant between two groups(P>0.05). CONCLUSION Compared with PLA, DSA is superior in clinical indexes such as operation time, intraoperative blood loss, incision length, first landing time, length of hospitalization and Harris score in the first month after operation in hemi hip replacement, and has comparative advantages in promoting early postoperative rehabilitation of elderly patients with femoral neck.

OBJECTIVE: To study the effect of ultrasound-guided fascia iliaca compartment block on perioperative analgesia and postoperative complications in geriatric patients with hip fractures. METHODS: A total of 127 elderly patients undergoing hip fracture surgery from January 2021 to September 2021 were randomized to receive ultrasound-guided continuous fascia iliaca compartment block(group F) either intravenous analgesia control group(group C). There were 62 cases in group F, including 19 males and 43 females with an average age of (82.4±7.2) years old ranging from 66 to 95 years old, involving 25 femoral neck fractures and 37 femoral intertrochanteric fractures. There were 65 cases in control group, including 18 males and 47 females, with an average age of (81.4±8.7) years old ranging from 65 to 94 years old, involving 29 femoral neck fractures and 36 femoral intertrochanteric fractures. The visual analogue scale(VAS), minimental state examination (MMSE), observer's assessment of alertness/sedation(OAA/S) scale, modified Bromage score, postoperative complications and general conditions during hospitalization in two groups were observed. RESULTS: The resting and exercise VAS at 30 min after block, anesthesia placement and 6, 24 and 48 h after surgery were lower than those in group C(P<0.05). In group F, MMSE scores at 12 h before surgery, and 1, 3 d after surgery and OAA/S scores at 3 d after surgery were higher than those in group C(P<0.05). The incidence of adverse effects and the number requiring additional analgesia were lower than those in group C(P<0.05). Group F had better perioperative analgesia satisfaction and hospital stay than group C(P<0.05). But there was no significant difference regarding Bromage score and 30-day mortality between two group(P>0.05). CONCLUSION Ultrasound-guided continuous fascia iliacus space block was safe and effective for elderly patients with hip fracture, and could significantly reduce perioperative pain, improve postoperative cognitive function, and reduce postoperative complications, thereby shortening hospital stay and improving the quality of life during hospitalization.

OBJECTIVE: To explore incidence, risk factors and the relationship between preoperative heart failure and prognosis in elderly patients with hip fracture. METHODS: A retrospective analysis was performed on 1 569 elderly patients with hip fracture treated from January 2012 to December 2019, including 522 males and 1 047 females, aged 81.00 (75.00, 90.00) years old;896 intertrochanteric fractures and 673 femoral neck fractures. Patients were divided into heart failure and non-heart failure groups according to whether they developed heart failure before surgery, and heart failure was set as the dependent variable, with independent variables including age, gender, fracture type, comorbidities and hematological indicators, etc. Univariate analysis was performed at first, and independent variables with statistical differences were included in multivariate Logistic regression analysis. Independent risk factors for preoperative heart failure were obtained. The length of hospital stay, perioperative complications, mortality at 30 days and 1 year after surgery were compared between heart failure and non-heart failure groups. RESULTS: There were 91 patients in heart failure group, including 40 males and 51 females, aged 82.00 (79.00, 87.00) years old;55 patients with intertrochanteric fracture and 36 patients with femoral neck fracture. There were 1 478 patients in non-heart failure groups, including 482 males and 996 females, aged 81.00(75.00, 86.00) years old;841 patients with intertrochanteric fracture and 637 patients with femoral neck fracture. There were significant differences in age, sex, coronary heart disease, arrhythmia and dementia between two groups(P<0.05). Multivariate Logistic analysis of statistically significant factors showed that males(OR=1.609, P=0.032), age(OR=1.032, P=0.031), arrhythmia(OR=2.045, P=0.006), dementia (OR=2.106, P=0.014) were independent risk factor for preoperative heart failure. The 30-day and 1-year mortality rates were 9.9% and 26.4% in heart failure group and 3.6% and 13.8% in non-heart failure group, respectively;and had statistical significance between two groups (P<0.05). There were significant differences in pulmonary infection, cerebrovascular complications and cardiovascular complications between two groups (P<0.05). The duration of hospitalization in heart failure group was (16.21±10.64) d compared with that in non-heart failure group (13.26±8.00) d, and the difference was statistically significant (t=2.513, P=0.012). CONCLUSION Male, old age, arrhythmia and dementia are independent risk factors for heart failure after hip fracture in elderly patients. Patients with preoperative heart failure have a higher incidence of postoperative pulmonary infection, cerebrovascular and cardiovascular complications, higher mortality at 30 d and 1 year after surgery, and longer hospital stay.

OBJECTIVE: To investigate CT values of cancellous bone in femoral neck in adults over 60 years with proximal femoral fractures. METHODS: From January 2020 to December 2020, a retrospective analysis was performed on 280 subjects aged 60 years or older who underwent bilateral hip CT examination, including 85 males and 195 females, 120 on the left side and 160 on the right side, aged 75 (66, 82) years old. One hundred thirty-six patients with proximal femoral fractures were included in study group and 144 patients without fractures were included in control group. GEOptima CT was used to scan and reconstruct horizontal, coronal and sagittal layers of proximal femur. CT values of cancellous bone in femoral neck were measured and compared between two groups. The relationship between CT values of cancellous bone of femoral neck and proximal femoral fracture was analyzed statistically. RESULTS: In terms of age, fracture group aged 79(73.3, 85.0) years old, non-fracture group aged 69.5 (64.0, 78.8) years old, and had significant difference in age between two groups (P<0.05). In terms of CT value, regional CT value in fracture group was 8.62(-3.62, 27.15) HU, which was lower than that in non-fracture group 34.31(-5.93, 71.74) HU(P<0.05). CT value on coronal view in fracture group was -8.48(-30.96, 17.46) HU, which was lower than that in non-fracture group 40.49(5.55, 80.71) HU (P<0.05). CT value on sagittal view in fracture group was -31.28(-54.91, -5.11) HU, which was lower than that in non-fracture group 7.74(-20.12, 44.54) HU (P<0.05). CT values on horizontal view in fracture group was 0.17(-23.13, 24.60) HU, which was lower than that in non-fracture group 46.40(10.42, 85.18) HU(P<0.05). The mean regional CT values among three planes in the fracture group were lower than those in the non-fracture group. Logistic regression analysis showed coronal CT value was influencing factors of proximal femoral fracture, and it could be written into regression equations that predict probability of fracture. CONCLUSION In adults aged over 60 years old, CT values of cancellous bone of femoral neck decreased with increasing age. The smaller CT value of cancellous bone of femoral neck, the greater risk of proximal femoral fracture.
