The Accuracy of In-State Prescription Monitoring Program Database and Electronic Medical Records Compared to Urine Toxicology Screening in Total Joint Arthroplasty Preoperative Evaluation.

Preoperative narcotic use is associated with poor postoperative pain management and worse outcomes after total joint arthroplasty (TJA). Therefore, identifying controlled substance use preoperatively is necessary. Electronic medical records (EMRs), prescription monitoring programs (PMP), or urine toxicology screening (UTS) are most commonly used.

Bias Does Not Exist in Treating Knee Periprosthetic Joint Infection Among Patients With Substance Use Disorder.

Debridement, antibiotics with implant retention (DAIR), and 2-stage revision are standard surgical interventions for treating knee periprosthetic joint infection (PJI). Patients with substance use disorder (SUD), especially addictive drug use disorder (DUD), have been shown to receive inferior medical care in many specialties compared with nonusers. The authors identified patients with a diagnosis of PJI after knee arthroplasty who received either DAIR or 2-stage revision with the Nationwide Inpatient Sample (NIS) database from 2010 to 2014.

Limb Lengthening after Primary Total Knee Arthroplasty: Customized Patient-Specific Instrumentation Does Not Affect Expected Limb Lengthening.

Introduction: Expectations for limb length differences after TKA are important for patient perception and outcomes. Limb length discrepancies may occur due to postoperative leg length increases, which can lead to decreased patient functionality and satisfaction and even possible litigation. The purpose of this study is to examine the frequency and extent of limb lengthening among various preoperative deformities and between two different implant systems.

Taper fretting corrosion with Stryker Anato stem after hip replacement.

We report a case of head-neck taper fretting corrosion in a patient who had a total hip replacement with a noncemented Stryker Anato femoral stem and a V40 metal head with a Stryker Tritanium hemispherical socket with a highly cross-linked polyethylene liner (metal on polyethylene) (Stryker, Mahwah, NJ, USA). A 57-year-old man presented with early-onset hip pain after right total hip arthroplasty. Workup was negative for infection.

Algorithm based automatic templating is less accurate than manual digital templating in total knee arthroplasty.

The purpose of the study was to evaluate the accuracy of a commercial automatic digital templating algorithm compared to manual digital templating in total knee arthroplasty (TKA). The study also evaluated if race and the presence of a standardized calibration marker on preoperative radiographs effect the accuracy of digital templating. One hundred twenty-five consecutive patients undergoing primary TKA were included in the study.

The Boston technique for acute point-of-care single-practitioner fracture stabilization of the lower extremity.

Background: Closed reduction with long leg casting is a widely practiced method of acute management of lower extremity fractures but may be cumbersome and time consuming. To our knowledge, only one method of single practitioner long leg casting has been previously reported. In this report, we describe the novel single-practitioner technique utilized at our institution for acute point-of-care temporizing management of lower extremity fractures.

Non-fatal haemophagocytic syndrome in an elderly patient.

A frail 78-year-old man presented with lethargy, fever, splenomegaly and pancytopenia. Bone marrow aspirate showed marked haemophagocytosis. A diagnosis of haemophagocytic syndrome secondary to diffuse splenic large B-cell lymphoma was eventually made.
