OBJECTIVE: To investigate the feasibility and effectiveness of the novel bone hook combined with finger-guided technique in the treatment of irreducible intertrochanteric femoral fractures in elderly. METHODS: Between January 2021 and August 2023, 23 elderly patients with irreducible intertrochanteric femoral fractures were treated with the novel bone hook combined with finger-guided technique. There were 10 males and 13 females; the age ranged from 68 to 93 years (mean, 76.2 years). The time from injury to operation ranged from 36 to 76 hours (mean, 51.2 hours). According to the classification standard proposed by TONG Dake et alin 2021, there were 10 cases of typeⅠA, 1 case of typeⅠB, 6 cases of type ⅡA, 4 cases of type ⅡB, and 2 cases of type ⅡC. The operation time, intraoperative blood loss, intraoperative fluoroscopy frequences, and quality of fracture reduction were recorded. The fracture healing time and occurrence of postoperative complications were observed during follow-up. At last follow-up, the Harris scoring system was used to evaluate the hip joint function. RESULTS: The operation time was 42-95 minutes (mean, 52.1 minutes). The intraoperative blood loss was 40-420 mL (mean, 126.5 mL). Intraoperative fluoroscopy was performed 14-34 times (mean, 20.7 times). According to the criteria proposed by Chang et al, the quality of fracture reduction was rated as good in 20 cases and acceptable in 3 cases. All patients were followed up 6-20 months (mean, 10.2 months). X-ray film showed that all fractures healed with the healing time of 3.0-5.5 months (mean, 4.0 months). At last follow-up, the Harris score of the hip joint ranged from 82 to 97 points (mean, 90.4 points). Among them, 14 cases were rated as excellent and 9 cases as good. No complication such as coxa vara, cutting of the cephalomedullary nail, nail withdrawal, or nail breakage occurred during follow-up. CONCLUSION The treatment of elderly patients with irreducible intertrochanteric femoral fractures by using the novel bone hook combined with finger-guided technique can achieve high-quality fracture reduction and fixation, and has a good effectiveness.

Objective:The hemodynamic parameters of elderly patients with septic shock were measured simultaneously with pulse index continuous cardiac output(PiCCO)and thoracic electrical bioimpedance(TEB)to evaluate the accuracy of TEB and to provide empirical evidence for its clinical use.Methods:A total of 24 elderly patients with septic shock admitted to the intensive care unit of our hospital between July 2021 and December 2021 were retrospectively recruited.TEB and PiCCO hemodynamic monitoring were performed continuously in all patients, and hemodynamic data were collected for statistical analysis.Results:Cardiac output, cardiac index, stroke volume, stroke index and systemic vascular resistance measured by the two methods had no significant difference( P>0.05). The 95% confidence intervals in the Bland-Altman plots for cardiac output, CI, stroke volume, stroke index, and systemic vascular resistance were(-1.18, 1.25), (-0.65, 0.71), (-24.23, 37.00), (-12.93, 19.26)and(397.11, 425.83). In the Bland-Altman plots for cardiac output, cardiac index, stroke volume and systemic vascular resistance, 4.17% of the points(1/24)fell outside of the 95% confidence interval, and in the Bland-Altman plots for stroke index, 8.33% of the points(2/24)fell outside of the 95% confidence interval. Conclusions:TEB and PiCCO have good consistency in evaluating the hemodynamics of elderly patients with septic shock.Therefore, TEB can be recommended for community hospitals and used in elderly patients.
