ABSTRACT
Intrapelvic acetabular screw placement is a known complication of total hip arthroplasty and is associated with risks including damage to neurovascular and intrapelvic structures such as the external iliac vessels, obturator vessels, and iliopsoas muscles. Retrieval of intrapelvic acetabular screws is similarly fraught with risk, and appropriate imaging should be performed preoperatively. We report on a case of intrapelvic acetabular screw placement with abutment of the external iliac vein, which was managed with intraoperative venogram and intravenous ultrasound to maintain access to the external iliac vein and successfully show no vascular tear before and after screw removal.
ABSTRACT
This article aims to provide the information necessary to prevent femoral trial head loss and to offer information regarding retrieval of the trial head if it is lost within the surgical field. These techniques can be used to help guide practice in the future. A review of the literature was conducted using a computerized search of PubMed in regard to this issue to investigate how such an occurrence can be prevented and what steps can be taken if preventative measures fail.

Forty percent to 50% of patients may experience an immediate postoperative fever. Research suggests that these are of aseptic cause due to inflammatory mediators. This is a retrospective analysis of fevers in total hip arthroplasty (THA) and total knee arthroplasty (TKA) patients from 2006 to 2008. Thirty-six percent of THA and 31% of TKA patients developed a fever, with most developing a maximum temperature on postoperative day (POD) 2. The maximum mean temperature between the THA and TKA group was not significantly different. Fevers in the immediate postoperative period are a normal variant in patients undergoing THA or TKA. Urinalysis, urine culture and sensitivity, and chest x-ray are not required during this period because most of these fevers stem from aseptic causes.
