Ulnar-sided wrist pain can be a diagnostic challenge for clinicians and radiologists. The ulnar wrist has complex morphology and is composed of many small bone and soft tissue structures. Within these structures, a wide variety of pathologic conditions can occur. To successfully diagnose and treat these pathologic conditions, clinicians and radiologists must have a strong understanding of the advanced imaging techniques available to them. In this review, the authors present a brief review of the...

Abstract null Introduction null Fixation and arthroplasty remain the mainstays of surgical treatment of degenerative and traumatic shoulder pathology. They also constitute an appreciable sum of Medicare expenditure. With continued concern for declines in Medicare reimbursement across orthopedic surgery, it is important to understand how trends in reimbursement correlate to relative procedure volumes. Our aims were to describe temporal changes in procedure volumes, physician payment, and patient ...

Abstract Background Total Elbow Arthroplasty (TEA) has demonstrated promising functional outcomes for the treatment of complex distal humerus fractures. In many other joints, arthroplasty for trauma is associated with increased risks for acute postoperative complications. The purpose of this investigation is to identify the in-hospital and 30-day postoperative complications for TEA performed because of distal humerus fracture vs. arthritis, and to determine whether acute fracture is associated w...

Introduction: Relative value units (RVUs) are integral to the U.S. physician compensation system used by the Centers for Medicare & Medicaid Services. The use of 'work RVUs' (herein, wRVUs) is intended to reimburse physicians according to the amount of expertise and effort needed to safely and effectively perform a procedure. Our purpose was to determine: 1) the number of wRVUs/hour generated by common sports medicine surgical procedures; and 2) how patient characteristics, surgical approach, an...

The incidence of anterior cruciate ligament (ACL) reconstruction is increasing in the United States, particularly in the older athlete. Patients who undergo ACL reconstruction are at higher risk for undergoing total knee arthroplasty (TKA) later in life. TKA in patients with prior ACL reconstruction has been associated with longer operative time due in-part to difficulty with exposure and retained hardware. Outcomes after TKA in patients with prior ACL reconstruction are not well defined, with s...

Case A 78-year-old man was followed for an incidentally found, asymptomatic lesion in his right proximal femur that was unchanged radiographically for 11 years. He developed pain and was believed to have experienced a stress fracture through the lesion. The lesion was biopsied, showing a high-grade pleomorphic sarcoma with an underlying senescent intraosseous lipoma. He was ultimately treated with wide excision and reconstruction of the proximal femur. Conclusion This case highlights the importa...

CASE The expandable intramedullary cage (Conventus Orthopaedics) may treat 3- and 4-part proximal humerus fractures. Cage removal for symptomatic avascular necrosis with humeral head collapse requiring conversion to arthroplasty can be challenging because the cage's collapsing mechanism becomes inoperable after fracture consolidation. We present cage explantation followed by reverse total shoulder prosthesis placement in a 54-year-old man who underwent plate/cage fixation for a 3-part proximal h...
