Safety and reliability of external fixation for basicervical and intertrochanteric fractures in high-risk elderly patients.

ABSTRACT: Forty elderly patients with basicervical and pertrochanteric fractures were managed with uniplanar AO external fixator under regional anaesthetic block of the femoral nerve and lateral cutaneous nerve of the thigh from April 2003 to March 2006. The mean age of the patients was 67.9 +/- 5.5 years. External fixator application was performed under radiological control after closed reduction had been obtained. Comorbid factors, duration of surgery, duration of hospitalisation, complications, walking ability, time to union and mortality rate were recorded. Patients were followed up for a mean period of 12 +/- 4.5 months. Superficial pin tract infection occurred in 13 patients, healing in varus >10 degrees and with shortening >2 cm occurred in six patients, and one patient suffered a spontaneous ipsilateral femoral neck fracture after removal of the fixator. The mean time for union was 10.4 +/- 1.2 weeks. Rapid union rate and minor complications obtained in the present study are comparable to those obtained with standard internal fixation techniques. Minimal intraoperative blood loss, short operative time and early patient mobilisation are advantages signifying uniplanar external fixator application under regional anaesthetic block to be a viable option in treatment of basicervical and pertrochanteric fractures in high-risk elderly patients.

Project description:BackgroundLittle is known regarding the survival and functional recovery of elderly intertrochanteric hip fracture (IHF) patients after total hip arthroplasty (THA) versus percutaneous external fixation (PEF). This study aims to analyze the prognostic factors of THA and PEF in elderly IHF patients.MethodsA total of 155 consecutive elderly patients (mean age of 80 years) diagnosed with IHF were retrospectively reviewed from our database between January 1, 2010, and December 31, 2018. The preoperative, intraoperative and postoperative covariates were analyzed by two independent surgical cohorts: THA and PEF. The main outcomes included the hip function score, all-cause mortality within 1 year after surgery, and overall survival. Covariables and their influence on independent outcomes were analyzed using multivariate regression models.ResultsThe median follow-up period was 5.1 years, and 6 patients were lost to follow-up. At the endpoint, 70 of 85 patients treated with THA and 37 of 70 patients treated with PEF survived, exhibiting mean Harris hip scores of 84.4 and 69.0, respectively. The Kaplan-Meier curves and log-rank tests showed no significant difference in overall survival. After adjusting for the covariates, the surgical mode was a unique prognostic factor affecting hip function recovery, and two prognostic factors (leukocyte count and D-dimer) were correlated with 1-year all-cause mortality. Age at admission, fracture classification, D-dimer level and surgical mode were identified as prognostic factors affecting overall survival. After adjusting for the former three covariates, THA reduced the risk of death by 67.20% compared with PEF (HR 0.328, 95% CI, 0.121-0.890).ConclusionsDespite the nonsignificant difference in 1-year all-cause mortality, THA demonstrated superior midterm survival and hip function recovery in elderly IHF patients compared with PEF. Predictive factors, including age at admission, fracture classification, D-dimer level and surgical mode, are associated with the overall survival of IHF in high-risk elderly patients.

Project description:Background Currently, we found that double reverse traction repositor (DRTR) is a treatment with operation convenience and fast in our clinical work. However, the clinical efficacy and safety of DRTR in the reduction of unstable intertrochanteric fractures in elderly patients remain unknown. Therefore, the study aimed to compare the clinical efficacy and safety of DRTR and traction table (TT) in the reduction of unstable intertrochanteric fractures in elderly patients. Methods From October 2018 to December 2020, the elderly patients with unstable intertrochanteric fractures were reviewed. 22 patients treated with TT and 20 patients treated with DRTR met the inclusion criteria of this study, and baseline clinical characteristics were recorded. The reduction time, operation time, incision length and intraoperative blood loss were reviewed. The safety outcome was assessed by postoperative complications, and the efficacy outcomes were evaluated by the fracture healing time based on the radiographs conducted at each follow-up (1, 3, 6, 12 months after surgery) and hip function (hip flexion, Harris Hip Score) at the final follow-up (12 months after surgery). Results There were no significant differences in terms of demographics and fracture characteristics of cases enrolled. In DRTR group, the average intraoperative reduction time [(34.8±7.6) min] and the average operation time [(87.1±12.2) min] were superior to those [(56.6±9.3); (123.1±15.0) min] in TT group (P<0.0001). However, there were no statistical significance in terms of the average incision lengths [(6.4±0.9) vs. (6.8±1.1) cm; P=0.1619], , the average intraoperative blood loss [(152.6±22.9) vs. (146.8±20.7) mL; P=0.3941], the average fracture healing times [(13.8±1.5) vs. (14.4±1.8) weeks; P=0.2350] and the average Harris hip score a year after operation [(84.4±6.6) vs. (82.7±7.2); P=0.4496] between the two groups. One patient in TT group experienced lower extremity intermuscular venous thrombosis postoperatively. No other operation-related complications were observed postoperatively nor during follow-up. Conclusions Minimally invasive reduction with DRTR in unstable intertrochanteric fractures could effectively shorten the intraoperative reduction time and operation time in this study. Therefore, minimally invasive reduction with DRTR might be a good choice for intertrochanteric reduction of unstable intertrochanteric fractures.

Project description:AbstractThe optimal surgical treatment of intertrochanteric femur fractures (ITF) to minimize the increased mortality in geriatric patients with high anesthetic risk was investigated by comparing closed external fixation (EF), a minimal invasive and biological osteosynthesis technique, proximal femoral nail (PFN) and hemiarthroplasty (HA) methods.Three different surgical methods were performed to 167 patients who were admitted to our clinic for ITF between 2014 and 2020 and considered at high risk (American Society of Anesthesiologists III - American Society of Anesthesiologists IV) by the Anesthesiology and Reanimation Department. Patients with multi-trauma, osteoarthritis, those with malignancies and developmental hip dysplasia were excluded from the study. Group I included patients who underwent closed reduction - external fixation (n = 46), Group II included patients who underwent partial arthroplasty (n = 77), and Group III included those who received PFN (n = 44). All fractures were classified according to the Modified Evans (Kyle) method and divided into 2 categories as type 1-2 (stable) and type 3-4 (unstable).The mean operation duration was 23 minutes and follow-up time was 14 months in Group 1, in which there was no in-hospital mortality. Five patients died due to non-operative reasons within 1 year. The mean operation duration and follow-up time in Group 2 were 40 minutes and 12 months, respectively. Six patients (7.8%) died during the operation or hospitalization, while 17 patients died due to comorbidities within 1 year. In Group 3, the mean operation duration and follow-up time were 40 minutes and 13 months, respectively. One patient died during the operation and 1 patient (n = 2, 4.5%), within 24 hours in the postoperative intensive care unit. Seven patients died due to comorbidities within 1 year. Statistical analysis revealed that the mean duration of operation, postoperative hospital stay, overall mortality and blood product transfusion amount were significantly lower in the EF group compared to other treatment methods.Closed EF is the most reliable surgical method that can minimize mortality in geriatric patients compared to other surgical options, due to the short duration of the operation, no evacuation of the fracture hematoma, early mobilization, lack of blood transfusion requirement, and early union.
