BackgroundAs life expectancy of patients increases, more elderly patients are undergoing primary total hip arthroplasty (THA) and total knee arthroplasty (TKA). There is a general perception of increased risk of complications in elderly patients. Our objective was to analyse the incidence of in-hospital medical and surgical complications following THA and TKA in octogenarian and nonagenarians.Materials and methodsThis was a prospective review of 202 consecutive patients aged more than 80 years who underwent total hip and total knee arthroplasty (101 THA, 101 TKA) over an 18-month period. In this single-centre observational study, collected data included patient demographics, American Society of Anethesiologists (ASA) grade, length of hospital stay and peri-operative medical and surgical complications during their hospital stay.ResultsMedian age of patients was 83 years. Median ASA grade was 3. Mean length of hospital stay was 7.5 days. There were 14 major systemic complications in the THA group and 13 in the TKA group. While 1 major local complication occurred in each group, there were 6 minor local complications in THA and 7 in the TKA group. All the complications occurred within 5 post-operative days. There was no in-hospital mortality.ConclusionIn our study, we found that the incidence of peri-operative medical and surgical complications is higher in those over 80 years, compared to the published literature in patients of all age groups undergoing THA and TKA. Awareness of a higher incidence of major systemic complications should alert the treating surgeon to carry out comprehensive peri-operative management in this subset of patients, which could lead to better outcomes.

Purpose Predicted survival of a patient is the most important parameter that helps to guide the treatment of a patient with metastatic spinal cancer. We aimed to investigate the reliability of modified Tokuhashi score in the decisionmaking process in patients with metastatic spinal cancer. Methods We performed a review of our prospectively collected Metastatic Cancer Database over a period of 4 years (2007)(2008)(2009)(2010). Ninety consecutive patients who were treated for metastatic spinal cancer were enrolled. Data review included demographic details, source of primary cancer, duration of symptoms, location of metastases, calculated Karnofsky's performance status, and calculated survival based on modified Tokuhashi score. We divided the patients into 3 groups. Group A included patients with expected survival less than 6 months. Group B included patients with expected survival between 6 and 12 months. Group C included patients whose expected survival was more than 12 months. We compared the calculated expected survival to the actual survival in all three groups with all patients following up to a minimum of 1 year or until death. Statistical analysis was done by Chi-square test and the Fisher Exact test.Results The survival prediction in group C was significantly accurate in 80.9 % patients (P = 0.027). However, in groups A and B, only 36.1 and 9.1 % patients survived, respectively, as per predicted. (P [ 0.05). Conclusions We can conclude from this study that, when used alone, modified Tokuhashi score may not be a reliable tool to predict survival in all patient groups.
