Purpose Controversy exists regarding approach to treatment of pediatric patients with fibrous dysplasia. Methods We retrospectively reviewed medical records of seven patients who were treated at our institution for fibrous dysplasia by intramedullary rod fixation without bisphosphonate supplementation. Results Seven patients with a total of ten fibrous dysplasia lesion sites surgically treated by intramedullary rod fixation were included. Of these ten lesion sites, eight demonstrated pathologic fracture at the time of fixation. Complete fracture healing was observed in all eight sites, with no incidence of recurrent pathologic fractures examined radiographically. There were no major infections or neurologic deficits, and lesions appeared to stabilize. Conclusions In this series, intramedullary rod fixation proved to be successful in treatment of acute pathologic fracture and incompletely healed fibrous dysplasia lesions. We observed partial resolution of fibrous dysplasia lesions at all ten sites without significant long-term complications. Following treatment, there were no refractures. Level of evidence Level IV, case series.
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.
BackgroundWith 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.MethodsWe 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.ResultsOf 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.ConclusionsIsobaric 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
