RESUMO

Background: With the increasing interest in fast recovery and outpatient joint arthroplasty, short-acting local anesthetic agents and minimal narcotic use are preferred. Lidocaine is a fast-onset, short-duration local anesthetic that has been used for many years in spinal anesthesia. However, lidocaine spinal anesthesia has been reported to have a risk of transient neurologic symptoms (TNSs). The purpose of this study is to determine the safety and efficacy of single-dose lidocaine spinal anesthesia in the setting of outpatient joint arthroplasty. Methods: We performed a prospective study on 50 patients who received lidocaine spinal anesthesia in the setting of outpatient hip and knee arthroplasty. All patients received a single-shot spinal injection, with 2% isobaric lidocaine along with titrated propofol sedation. We evaluated demographic data, length of motor blockage, time to ambulation, time to discharge readiness, patient-reported symptoms of TNS. Results: Of the 50 patients studied, 11 had total hip arthroplasty, 33 total knee arthroplasty, 5 unicompartmental knee arthroplasty, and 1 underwent isolated polyethylene liner exchange in a total knee arthroplasty. The average total duration of motor blockade was 2.89 hours (range 1.73-5.17, standard deviation 0.65). Average time from postanesthesia care unit to return of motor function was 0.58 hours (range 0-1.5, standard deviation 0.48). None of the patients reported TNS. Conclusions: Isobaric lidocaine spinal anesthesia appears to be a safe and effective regimen for outpatient hip and knee arthroplasty. All patients were discharged on the day of surgery with isobaric lidocaine spinal injection. There were no reports of TNSs.

RESUMO

BACKGROUND: Ankle fragility fractures are difficult to treat due to poor bone quality and soft tissues as well as the near ubiquitous presence of comorbidities including diabetes mellitus and peripheral neuropathy. Conventional open reduction and internal fixation in this population has been shown to lead to a significant rate of complications. Given the high rate of complications with contemporary fixation methods, the present study aims to critically evaluate the use of acute hindfoot nailing as a percutaneous fixation technique for high-risk ankle fragility fractures. METHODS: In this study, we retrospectively evaluated 31 patients treated with primary retrograde tibiotalocalcaneal nail without joint preparation for a mean of 13.6 months postoperatively from an urban Level I trauma center during the years 2006-2012. RESULTS: Overall, there were two superficial infections (6.5%) and three deep infections (9.7%) in the series. There were 28 (90.3%) patients that went on to radiographic union at a mean of 22.2 weeks with maintenance of foot and ankle alignment. There were three cases of asymptomatic screw breakage observed at a mean of 18.3 months postoperatively, which were all treated conservatively.. CONCLUSIONS: This study shows that retrograde hindfoot nailing is an acceptable treatment option for treatment of ankle fragility fractures. Hindfoot nailing allows early weightbearing, limited soft tissue injury, and a relatively low rate of complications, all of which are advantages to conventional open reduction internal fixation techniques. Given these findings, larger prospective randomized trials comparing this treatment with conventional open reduction internal fixation techniques are warranted.

RESUMO

We performed a retrospective review in a matched group of patients on the use of robotic-assisted UKA implantation versus UKA performed using standard operative techniques to assess differences between procedures. While both techniques resulted in reproducible and excellent outcomes with low complication rates, the results demonstrate little to no clinical or radiographic difference in outcomes between cohorts. Average operative time differed significantly with, and average of 20 minutes greater in, the robotic-assisted UKA group (P=0.010). Our minimal clinical and radiographic differences lend to the argument that it is difficult to justify the routine use of expensive robotic techniques for standard medial UKA surgery, especially in a well-trained, high-volume surgeon. Further surgical, clinical and economical study of this technology is necessary.

RESUMO

There has been an increase in the prevalence of morbid obesity and the demand for total knee arthroplasty (TKA). Physicians must help patients with bilateral knee arthritis to make informed decisions regarding whether to undergo staged, sequential, or simultaneous TKA. The purpose of this study was to evaluate the perioperative complications of 2-team simultaneous bilateral TKA in the morbidly obese. The authors performed a retrospective review of the records at a single tertiary hospital from 1997 to 2007 and identified 35 morbidly obese (body mass index [BMI] greater than 40 kg/m(2)) patients who had undergone unilateral TKA, as well as 42 morbidly obese and 79 nonobese (BMI less than 30 kg/m(2)) patients who underwent simultaneous bilateral TKA. Clinical, operative, and postoperative variables and complication rates were recorded. Clinical variables were similar between the morbidly obese TKA patients. The bilateral group had significantly increased operative times (132.4 vs 115.5 minutes; P<.01), intravenous fluids (2556.1 vs 2114.7 mL; P=.03), percentage transfused (64.2% vs 11.4%; P<.01), days in the hospital (3.6 vs 3.2 days; P=.03), and discharge rates to rehabilitation facility (72.7% vs 48.6%; P=.01). Major and minor complications were few and comparable, with the need for manipulation under anesthesia in unilateral TKA (11.4%; P=.04) as the only significant difference between groups, including when comparing bilateral nonobese TKAs with bilateral morbidly obese TKAs. The authors feel that morbidly obese patients may undergo 2-team simultaneous bilateral TKA after careful discussion regarding some of the differences in short-term outcomes.
