Investigation of the Medium- and Long-Term Results of a Pioneering Method in the Treatment of Geriatric Intertrochanteric Femur Fractures: Osteosynthesis Using the WALANT Technique

Background/Objectives: Femoral neck and proximal femur fractures in the elderly can result from low-energy trauma due to osteoporotic changes and contribute significantly to increased morbidity and mortality. Despite various treatment options, closed reduction and internal fixation (CRIF) with intramedullary nails has become the predominant approach. While a minimally invasive approach reduces complications and speeds recovery, this outcome is not always feasible in practice. The primary surgical goal remains achieving a stable and precise fracture reduction, favoring CRIF when possible. Our study aims to evaluate the clinical, radiological, and functional outcomes of patients operated on using the Wide-Awake Local Anesthesia No Tourniquet (WALANT) technique. Methods: Patients who underwent surgery for intertrochanteric femur fractures between June 2019 and June 2021 were analyzed. Patients who were between 75 and 90 years old and had undergone surgery with a proximal femoral nail (PFN) were included in the study. Patients were excluded if they required general anesthesia, if an acceptable reduction could not be achieved with the PFN, if they did not attend the last follow-up examination, or if the follow-up period was <4 years. Patients were functionally assessed using the Harris hip score at the 6th month and at the last follow-up and using the visual analog scale at the surgery, at the 4th hour after surgery, and at the time of discharge. For radiological assessment, the classification of reduction quality and the measurement of the tip–apex distance were used. Results: Forty patients (22F/18M) were included in the study. Their mean age was 83.0 ± 2.9 years. The mean time from trauma to surgery was 6.8 ± 2.3 h. Patients were mobilized on average 1.53 ± 0.8 h after surgery, and the mean hospitalization time was 27.4 ± 8.1 h. No statistically significant decrease in hemoglobin value was observed before or after surgery (p = 0.476). The Harris hip score was 73.3 ± 3.2 at the 6th month postoperatively and 74.9 ± 2.5 at the last follow-up (p = 0.296). The reduction quality was found to be poor in only two patients. Conclusions: The WALANT technique’s promising results in terms of pain management, blood loss control, and early mobilization show that it is a viable alternative to conventional anesthesia methods in geriatric hip fractures.
