Acute total hip arthroplasty for older patients with acetabular fractures: A meta-analysis.

OBJECTIVE: Multiple treatment options for acetabular fractures in geriatric patients exist. However, no large-scale studies have reported the outcomes of acute total hip arthroplasty (THA) in this patient population. We systematically evaluated all available evidence to characterize clinical outcomes, complications, and revisions of acute THA for acetabular fractures in geriatric patients. METHODS: Meta-analysis of 21 studies of 430 acetabular fractures with mean follow-up of 44 months (range, 17-97 months). Two independent researchers searched and evaluated the databases of Ovid, Embase, and United States National Library of Medicine using a Boolean search string up to December 2019. Population demographics and complications, including presence of heterotopic ossification (HO), dislocation, infection, revision rate, neurological deficits, and venous thromboembolic event (VTE), were recorded and analyzed. RESULTS: Weighted mean Harris Hip Score was 83.3 points, and 20% of the patients had reported complications. The most common complication was HO, with a rate of 19.5%. Brooker grade III and IV HO rates were lower at 6.8%. Hip dislocation occurred at a rate of 6.1%, 4.1% of patients developed VTE, deep infection occurred in 3.8%, and neurological complications occurred in 1.9%. Although the revision rate was described in most studies, we were unable to perform a survival analysis because the time to each revision was described in only a few studies. The revision rate was 4.3%. CONCLUSIONS: Acute THA is a viable option for treatment of acetabular fracture and can result in acceptable clinical outcomes and survivorship rates in older patients but with an associated complication rate of approximately 20%. Considering the limited treatment options, THA might be a viable alternative for appropriately selected patients.

Periarticular injection and continuous femoral nerve block versus continuous femoral nerve block alone on postoperative opioid consumption and pain control following total knee arthroplasty: Randomized controlled trial.

Continuous femoral nerve block (CFNB) has been used to prevent the breakthrough pain after total knee arthroplasty (TKA). Multimodal drug injection (PMDI) has also been shown to decrease opioid consumption and pain. We investigated whether the use of PMDI further improves analgesic and rehabilitation outcomes when used in conjunction with CFNB. This is a prospective randomized controlled study of 44 patients undergoing primary TKA. The treatment group (n = 23) received a PMDI of combined ropivacaine, epinephrine, ketorolac and morphine, and the controlled group (n = 21) received saline at wound closure. Total opioid consumption, pain scores, knee range of motion (ROM) outcomes, length of stay, and patient satisfaction were measured and compared. The total consumption of morphine is similar between the two groups (52.6 ± 40.6 vs. 41.5 ± 32.9, p = 0.325). The mean morphine consumption of the treatment group was significantly lower than the control at 4 h after surgery (4.2 ± 5.5 vs. 11.3 ± 8.1, p = 0.002) but comparable on POD1, POD2, and POD3. The mean pain scores were significantly higher in the treatment group than the control group at POD2 (at rest: 47.3 ± 29.1 vs. 23.8 ± 20.6, p = 0.004; after PT: 57.7 ± 25.4 vs. 35.2 ± 26.8, p = 0.007) and POD3 (at rest: 30.9 ± 30.3 vs. 14.8 ± 20.9, p = 0.045; after PT: 50.2 ± 30.6 vs. 29.0 ± 32.1, p = 0.035), and not significantly different at 4 h after surgery or at POD1. Mean maximal knee flexion ROM in degrees during active and active assisted mobilization showed no significant difference between the control and the treatment groups on POD2 and POD3. The mean length of stay of the treatment group is significantly longer than the control group (5.1 ± 2.1 vs. 3.8 ± 1.6, p = 0.032). At discharge, no significant difference exists between the two groups for mean patient satisfaction. The addition of PMDI led to a decrease in opioid consumption in the immediate postoperative period but with no significant difference in the total consumption within the first three days postoperatively. This finding provides an opportunity for appropriate preoperative treatment and education for both patients and caregivers.

Medical therapy for atherosclerotic cardiovascular disease in patients with myocardial injury after non-cardiac surgery.

BACKGROUND: Myocardial injury after non-cardiac surgery (MINS) is a common post-operative cardiovascular complication and is associated with short and long-term mortality. The objective of this study was to describe the contemporary management of patients with and without MINS after total joint and spine orthopedic surgery at a large urban health system in the United States. METHODS: Adults admitted for total joint and major spine surgery from January 2013 through December 2015 with ≥1 cardiac troponin (cTn) measurement during their hospitalization were identified. MINS was defined by a peak cTn above the 99th percentile of the upper reference limit. Demographics, medical comorbidities, and admission and discharge medications were reviewed for all patients. RESULTS: A total of 2561 patients underwent 2798 orthopedic surgeries, and 236 cases of MINS were identified. Patients with MINS were older (71.9 ±â€¯10.9 vs. 67.0 ±â€¯10.0, p < 0.001) and more likely to have cardiovascular risk factors, including hypertension, chronic kidney disease, prior stroke, coronary artery disease, prior MI, and a history of heart failure. Among patients with MINS, only 112 (47.5%) were discharged on a combination of aspirin and statin. Patients with MINS were more likely to be prescribed a statin (154 [65.3%] vs. 1463 [57.1%], p = 0.018), beta-blocker (147 [62.3%] vs. 1194 [46.6%], p < 0.001), and oral anticoagulation (65 [27.5%] vs. 436 [17.0%], p < 0.001) than patients without MINS. CONCLUSIONS: The proportion of patients with MINS who were prescribed medical therapy for atherosclerotic cardiovascular disease was low. Additional efforts to determine optimal management of MINS are warranted.
