e retrospectively reviewed 45 hip arthroplasties which were performed over a period of 20 years in 38 patients with cirrhosis of the liver. There was a high perioperative 30-day complication rate (26.7%). Advanced cirrhosis was associated with a higher risk of complications (p = 0.004) as also was increased age, a high level of creatinine, a low level of albumin, a low platelet count, ascites, encephalopathy and an increased operative blood loss. The survival of the prosthesis at five years was 77.8% and infection was a major cause of failure.In view of the high rate of early complications and the limited longevity of the prosthesis, surgeons who perform hip arthroplasty on such patients should counsel them appropriately preoperatively.

The purpose of this study was to describe the surgical technique and to investigate results of a modified two-incision total hip replacement using either intraoperative fluoroscopy or imageless navigation. Twenty-nine patients (30 hips) with a minimum follow-up of one year were enrolled in this study. The patients were evaluated at 3, 6, 12 weeks, 6 months, and 1-year. The functional recovery as represented by the Harris hip score and WOMAC scale were better in the fluoroscopy group of patients at the early postoperative stage (3 wks). Thereafter, both groups showed rapid recovery with no difference in scores. Injury to the lateral femoral cutaneous nerve was the most commonly seen complication and it occurred in 6 hips (fluoroscopy 2; imageless 4). The symptoms were transient and resolved in 6 months in all 6 cases. This study demonstrated that the role of intraoperative fluoroscopy could safely be replaced by an imageless navigation system for the MIS-2 THA.
