OBJECTIVE: For elderly femoral neck fracture patients, anemia is one of the most common complications, increasing the risk of postoperative adverse events. Tranexamic acid (TXA) has been widely applied to the perioperative blood management. However, the optimal route of TXA administration in elderly femoral neck fracture remains unclear. The aim of this study is to evaluate the efficacy and safety of oral and intravenous (IV) application of TXA in elderly patients with femoral neck fracture undergoing total hip arthroplasty (THA) and hemiarthroplasty (HA).
METHODS: All elderly patients aged over 65 years old diagnosed with femoral neck fracture admitted to the trauma orthopedics from August 1, 2020 to February 28, 2022 were enrolled in this prospective cohort study. Participants were divided into three groups: oral group: TXA 2g orally 2 h before incision; IV group: intravenous infusion of TXA 1g 15 min before incision; and control group: usual hemostatic method. The primary outcomes were total blood loss, allogeneic transfusion rate, and postoperative thromboembolic events. SPSS 23.0 (IBM, Armonk, NY, USA) was used for statistical analysis, and p ≤ 0.05 was considered statistically significant.
RESULTS: A total of 100 patients were enrolled, including 32 cases in the oral group, 34 cases in the IV group and 34 cases in the control group. Compared with the control group, the total perioperative blood loss in the oral and IV groups was significantly decreased (763.92 ± 358.64 mL vs 744.62 ± 306.88 mL vs 1250.60 ± 563.37 mL, p = 0.048). No significant difference was identified between the oral and IV groups (p = 0.970). The rate of allogeneic transfusion was lower in the oral and IV groups than in the control group, but the difference had no statistical significant (6 vs 5 vs 12, p = 0.108), However, subgroup analysis showed that the IV and oral groups in patients who underwent THA have significant lower transfusion rate compared with the control group (1 vs 3 vs 7, p = 0.02). During 6 months follow-up, no thromboembolic events were identified. Two patients (one from the oral group and one from the control group) died of respiratory failure. The cost of blood management from the oral group was significantly lower than IV (p < 0.001) and control groups (p = 0.009).
CONCLUSIONS: Elderly patients with femoral neck fracture undergoing THA can benefit from both IV and oral administration of tranexamic acid. The results of these two administration routes are similar in safety and effectiveness. A similar tendency was observed in patients undergoing HA. Oral TXA is more cost-benefit compared with intravenous applications.

BACKGROUND: The 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.
METHODS: We 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.
RESULTS: The 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.
CONCLUSIONS: The 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.

BACKGROUND: Various surgical techniques and conservative therapies are useful tools for treating proximal humerus fractures (PHFs), but it is important to understand how to properly utilize them. Therefore, we performed a systematic review and network meta-analysis to compare and rank the efficacy and safety of medical treatments for PHF.
METHODS: PubMed, Embase, the Cochrane Library, and the ClinicalTrials.gov databases were systematically searched for eligible randomized controlled trials (RCTs) from inception until June 2022. Conservative therapy-controlled or head-to-head RCTs of open reduction internal fixation (ORIF), intramedullary nailing (IMN), hemiarthroplasty (HA), and reverse total shoulder arthroplasty (RTSA) used for the treatment of adult patients with PHF were included. The surface under the cumulative ranking (SUCRA) probabilities were applied to compare and rank the effects of medical treatments for PHF.
RESULTS: Eighteen RCTs involving 1,182 patients with PHF were selected for the final analysis. Mostly baseline characteristics among groups were well balanced, and the imbalanced factors only included age, injury type, medial comminution, blood loss, and cognitive function in single trial. The SUCRA probabilities found that RTSA provided the best effect on the Constant-Murley score (SUCRA: 100.0%), and the disabilities of the arm, shoulder and hand (DASH) score (SUCRA: 99.0%). Moreover, HA (SUCRA: 85.5%) and RTSA (SUCRA: 68.0%) had a relatively better effect on health-related quality of life than the other treatment modalities. Furthermore, conservative therapy (SUCRA: 84.3%) and RTSA (SUCRA: 80.7%) were associated with a lower risk of secondary surgery. Finally, the best effects on the risk of complications are varied, including infection was observed with conservative therapy (SUCRA: 94.2%); avascular necrosis was observed in HA (SUCRA: 78.1%), nonunion was observed in RTSA (SUCRA: 69.6%), and osteoarthritis was observed in HA (SUCRA: 93.9%).
CONCLUSIONS: This study found that RTSA was associated with better functional outcomes, while the comparative outcomes of secondary surgery and complications varied. Optimal treatment for PHF should consider patient-specific factors.

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).
CONCLUSIONS: 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.

UNASSIGNED: The objective of this study was to assess the long-term survival rate, complications, as well as the clinical and radiological outcomes of hemiarthroplasty and total hip arthroplasty using constrained polyethylene liners in patients with ischemic stroke.
UNASSIGNED: This study was a retrospective cohort study that included patients with ischemic stroke who underwent hip arthroplasty from March 2010 to September 2017. In the Constrained Acetabular Liners (CAL) group, patients received an uncemented acetabular shell with a constrained polyethylene liner. The Dual Mobility (DM) group underwent hemiarthroplasty (HA). Additionally, hip function, range of motion, quality of life, the incidence of clinical complications, and prosthesis stability were investigated.
UNASSIGNED: 96 patients with unilateral femoral neck fractures who underwent hip replacement with CAL were included in the CAL group, while 103 patients who underwent hip replacement with a dual mobility head were included in the DM group. VAS, and SF-36 data were available for both CAL and DM groups. At the 1-year postoperative follow-up, the HHS in the CAL group was significantly lower than that in the DM group (80.83 ± 3.91 vs. 83.17 ± 4.15, P < 0.05). The VAS score in the CAL group peaked at the 1-year follow-up (2.07 ± 0.91 vs. 1.49 ± 0.85, P < 0.05). However, there were no significant differences between the two groups in terms of HSS, VAS, and SF-36 at the last follow-up after surgery. Operative time and the amount of bleeding in the DM group were significantly lower than those in the CAL group (105.30 ± 29.68 vs. 94.85 ± 31.07; 355.11 ± 123.95 vs. 302.22 ± 107.68, P < 0.05). Additionally, there was no significant difference in the mean leg length discrepancy between the two groups.
UNASSIGNED: The clinical, imaging, and postoperative complications of the CAL and DM groups were analyzed. The prognosis for DM appears to be more beneficial for early patient recovery, but a higher likelihood of recurrent dislocation is observed. CAL offers excellent stability for primary THA in high-risk patients; however, attention should be given to preventing aseptic loosening.

UNASSIGNED: Patients with neurological disorders often experience a high incidence of postoperative complications following proximal femur replacement (PFR) surgery. The orthopaedist faces a significant difficulty in treating Parkinson\'s disease (PD) because of the weakened bone condition, excessive muscle tension, and increased risk of fractures. The objective of this research is to assess the impact of PD on PFR following tumor removal.
UNASSIGNED: A retrospective study was conducted from 2010 to 2020, focusing on a solitary institution, analyzing 9 patients diagnosed with PD who underwent PFR with hemiarthroplasty as a result of tumor removal. The study consists of 2 men and 7 women, with an average age of 71 (SD, 12) years. We assessed the outcomes after surgery in terms of pain management, quality of life, functional ability, occurrence of complications, and survival durations.
UNASSIGNED: All nine patients underwent planned surgeries. Intraoperative complications was not observed. The average length of the follow-up period was 24 (SD, 20) months, ranging from 8 to 72 months. Despite the fact that 8 patients passed away due to tumor progression, the endoprostheses were still well at that point. The preoperative VAS score of 7 (SD, 1.87) decreased to a postoperative score of 2 (SD, 1.32). The KPS was improved to73 (SD, 7) from 52 (SD, 14), postoperatively. Post-surgery, there were notable enhancements in both pain levels and the overall quality of life scores. Following the surgical procedure, individuals are able to ambulate steadily, resuming their regular daily routines. Living patients had an average MSTS score of 21 (SD, 2.5), ranging from 17 to 25. In total, there were four (44.4%) patients suffered complications after surgery, comprising of one wound dehiscence, one prosthetic fracture, one hip dislocation, and one local recurrence.
UNASSIGNED: Significant improvements in function and pain relief can be achieved through PFR with hemiarthroplasty following tumor removal in patients with PD. The implementation of thorough preparation and carefull nursing results in reduced complications and improved outcomes in PD patients.
