ABSTRACT: Objective: To investigate whether the time from injury to surgery (≤48 h) affects periprocedural indicators, postoperative pain, hip function recovery, and complication rates in elderly patients with femoral neck fractures undergoing total hip arthroplasty in western Guangxi region. Methods: A retrospective cohort study design was employed. A total of 120 elderly (≥65 years old) patients with femoral neck fractures who underwent total hip arthroplasty at the Department of Joint Surgery, Baise People’s Hospital from September 2020 to June 2026 were enrolled. Patients were divided into early surgery group (≤48 h, n = 60) and delayed surgery group (>48 h, n = 60) based on the time from injury to surgery. General information, intraoperative blood loss, hospital stay, preoperative and postoperative hemoglobin and albumin levels, preoperative D-dimer, visual analogue scale (VAS) scores at various postoperative time points, Harris hip scores at 1 week and 1 month postoperatively, and postoperative complication rates were compared between the two groups. Results: No statistically significant differences were found in gender or age between the two groups (P > 0.05). The early surgery group had a shorter hospital stay than the delayed surgery group [(8.62 ± 4.83) d vs (12.07 ± 5.70) d, P 0.05). The early surgery group had higher preoperative albumin levels than the delayed surgery group [(40.65 ± 3.65) g/L vs (38.93 ± 2.92) g/L, P = 0.005], with no statistically significant difference in postoperative albumin levels (P > 0.05). The early surgery group had higher preoperative D-dimer levels [M = 5672.5 vs 1372.0 ng/ml, P = 0.001]. Harris scores at 1 week and 1 month postoperatively were higher in the early surgery group than in the delayed surgery group [(60.42 ± 3.71) vs (56.83 ± 3.20) points; (66.57 ± 4.04) vs (62.38 ± 2.31) points, both P 0.05). No statistically significant differences were found in prosthesis-related complications, postoperative hematoma/deep vein thrombosis/pneumonia rates between the two groups (P > 0.05). Conclusion: For elderly patients with femoral neck fractures in western Guangxi region, performing hip arthroplasty within 48 h after injury, provided that the general condition permits, can shorten hospital stay, alleviate early postoperative pain, and promote hip function recovery. However, the effects on intraoperative blood loss, postoperative laboratory indicators, and complication rates require validation through larger sample studies.
