Embolism After Injection of a Calcium Sulfate Bone Graft Substitute: A Case Report.

Case: A 66-year-old man presented with new left hip pain after total hip arthroplasty 21 years earlier. Computed tomography imaging revealed massive osteolysis involving the ileum behind the well-fixed acetabular component. The patient was indicated for head and liner exchange with grafting of the osteolytic lesion.

Risk Factors for Retinal Detachment: A Case-Control Study.

Objective: The aim of this study was to investigate risk factors for retinal detachment or tear (RD/T), and follow up two studies that found increased risk from work-related heavy lifting.

Methods: We conducted a case-control study including 200 cases of RD/T and 415 controls. Participants completed a questionnaire covering general health, vision, and physical exertion.

How Has COVID-19 Affected Our Orthopedic Implant Industry Partners? Implications for the Surgeon-Industry Relationship in 2020 and Beyond.

Background: The COVID-19 pandemic has had far-reaching societal and financial consequences. The purpose of this study was to evaluate how COVID-19 has affected AAHKS industry partners and the surgeon-industry relationship, emphasizing education, resource allocation, and strategic direction for the second half of 2020.

Methods: AAHKS industry partners were contacted to participate in a blinded survey and optional interview with the AAHKS Industry Relations Committee.

Cadaveric simulation of a pes cavus foot.

Background: The pes cavus deformity has been well described in the literature; relative bony positions have been determined and specific muscle imbalances have been summarized. However, we are unaware of a cadaveric model that has been used to generate this foot pathology. The purpose of this study was to create such a model for future work on surgical and conservative treatment simulation.

Intraocular adenosine levels in normal and ocular-hypertensive patients.

Purpose: Adenosine receptors modulate several ocular responses; however, our understanding of factors that influence ocular extracellular adenosine levels is limited. The objective of this study was to evaluate how changes in intraocular pressure (IOP) influence endogenous levels of the purines adenosine and inosine, in the aqueous humor of normal and ocular-hypertensive patients.

Patients And Methods: Informed consent was obtained from 51 individuals undergoing cataract extraction or glaucoma surgical procedures.

Rapid diagnosis and treatment of mycobacterial keratitis after laser in situ keratomileusis.

We report the results of laser in situ keratomileusis (LASIK) in a 51-year-old woman with subsequent mycobacterial keratitis diagnosed by staining with acid-fast and fluorochrome methods, a technique known to have good sensitivity and specificity for mycobacteria. A rapid diagnosis was made without waiting for cultures, and treatment was instituted, including tapering of topical steroids and appropriate antibiotic therapy. The result was preservation of the LASIK flap and a favorable visual outcome at 6 months.
