RESUMO
BACKGROUND: Trochanteric bursitis (TB) is a prevalent complication following total hip arthroplasty (THA), with increased offset hypothesized as a potential risk factor. This study investigated potential TB predictors in THA patients, including radiographic measurements of offset and leg length, comorbidities, and patient characteristics. METHODS: In this retrospective cohort study, all THA patients from a single academic tertiary care center between 2005 and 2021 were reviewed. Exclusion criteria included less than one-year follow-up, osteonecrosis, or fracture. Manual radiographic measurements of offset (acetabular, femoral, and total) and leg length from preoperative and postoperative antero-posterior pelvis X-rays were taken, with scaling using femoral cortical diameter. Univariable and multivariable Cox proportional hazard models were employed to estimate TB risk. RESULTS: Of 1,094 patients, 103 (9.4%) developed TB, with a median (Q1, Q3) time to presentation of 41.8 weeks (25.5, 66.9). In univariable models, only sex was associated with increased TB risk, with women exhibiting a 1.79 times increased risk (hazard ratio: 1.79 (1.16, 2.76), P = .009). Changes in acetabular offset, femoral offset, total offset, and leg length between preoperative and postoperative radiographs were not associated with an increased risk of developing TB in the univariate or multivariate models. Furthermore, various offset thresholds were evaluated, with no amount of increased offset showing increased TB risk. CONCLUSIONS: This study found no relationship between femoral, acetabular, or total offset and TB following THA. These findings suggest that surgeons may consider adding offset for increased prosthetic stability in high-risk cases. However, given that this is a retrospective study, the authors are not advocating for the routine use of increased offset. The study identified women as a risk factor with a 1.79 times higher TB risk, highlighting the importance of counseling women patients on this heightened risk.
RESUMO
BACKGROUND: There is substantial media and patient interest in the safety of mesh for hernia repair. However, there is a lack of data regarding health-related quality of life (HRQOL) outcomes in patients who undergo inguinal hernia repair (IHR) with mesh. The purpose of this study is report short and long-term postoperative quality of life outcomes in patients following IHR with mesh. METHODS: We analyzed outcomes of 1720 patients who underwent IHR with mesh between 2008 and 2019 at a single institution from a prospectively maintained quality database. All surgeries were performed by four board-certified surgeons. HRQOL outcomes were measured using the Surgical Outcomes Measurement System (SOMS) and Carolinas Comfort Scale (CCS) surveys that were administered preoperatively, 3 weeks, 6 months, 1, 2, and 5 years postoperatively. Survey responses were summarized as mean with standard deviation or frequency with percentage. Postoperative SOMS scores were compared to preoperative scores using the two-tailed paired t test with a significance level of p < 0.05. RESULTS: One (0.1%) patient experienced a mesh infection postoperatively. In terms of complications, 159 (9.2%) developed a seroma, 31 (1.8%) a hematoma, and 36 (2.1%) patients experienced a recurrence. SOMS Pain Impact, SOMS Pain Quality, and SOMS Pain visual analog scale at 3 weeks, 6 months, 1 year, 2 years, and 5 years were all improved from preoperative (all p < 0.05). At 5 years postoperatively, only 3.9%, 3.2%, and 3.1% of patients reported severe or disabling sensation of mesh, pain, and movement limitations, respectively. CONCLUSION: Inguinal hernia repair with mesh results in a low rate of complications. A minority of patients had severe or disabling symptoms at 5-year follow-up and generally reported improvements in pain impact and quality in long-term follow-up.
