ABSTRACT
BACKGROUND: This study compared outcomes of the direct anterior approach (DAA) and direct lateral approach (DLA) for treating displaced femoral neck fractures in active elderly patients. METHODS: This retrospective study included active elderly patients who sustained a displaced femoral neck fracture and underwent a cementless total hip arthroplasty either with a supine DAA or a decubitus DLA. Patients were assessed using the Harris hip score at discharge and at a 6-week follow-up. RESULTS: A total of 41 women and 18 men were included in the study. Of those, 22 underwent DLA and 37 received DAA, all performed by the same team. In both groups, 69% were women, mean age was 70 years, and mean BMI was 25.2. Mean hemoglobin loss was 2.3 g/dl between admission and the first post-operative day in both groups. Similar numbers in each cohort were discharged home rather than to a rehabilitation center. The patients who underwent the DAA experienced a 2-day reduction in their hospital stay compared to the DLA group (4.2 ± 1.9 vs. 6.8 ± 3.7, respectively; p < 0.001). The Harris hip score in the DAA group was significantly higher at the 6-week follow-up than in the DLA group (87.23 ± 7.75 vs. 81.23 ± 7.67, respectively; p < 0.031). CONCLUSIONS: The patients who underwent THA with the DAA demonstrated better short term outcomes compared to the alternative approach for displaced femoral neck fractures in active elderly patients. DAA helped patients regain independence faster and might decrease hospitalization and rehabilitation costs. Based on these results, we recommend using the DAA for active elderly patients with a displaced femoral neck fracture.
ABSTRACT
Introduction: Postoperative urinary retention (POUR) frequently complicates the course of patients following hip and knee arthroplasty. Intrathecal morphine (ITM) was identified as a significant risk factor for POUR. The objective of this study was to investigate the incidence and risk factors for POUR in fast-track total joint arthroplasty (TJA) under spinal anaesthesia (SA) with ITM. Methods: We conducted a retrospective study of our institutional joint registry of patients who underwent primary TJA under SA with ITM between October 2017 and May 2021. Preoperative (baseline demographics) and perioperative data were collected. The primary outcome was the incidence of POUR after 8 h or earlier, either due to lack of voiding or according to patient's complaints of bladder distension. Univariate and adjusted analyses were performed to identify predictors of POUR. Results: Sixty-nine patients who underwent total knee arthroplasty (TKA) and 36 patients who underwent total hip arthroplasty (THA) under SA with ITM were included in the study. POUR requiring bladder catheterisation was diagnosed in 21% of patients. Independent predictors of POUR were age over 65 years and male gender. Conclusions: SA with ITM for TJA is associated with high rates of POUR in males older than 65 years of age. Other previously identified risk factors such as intraoperative fluid administration or comorbidities may not be as influential.
