Article Synopsis
  • The golf club deformity is a serious malreduction after distal femur fracture fixation that can lead to knee problems and reduced function.
  • There is no agreement among orthopedic experts on the best way to treat these malunions.
  • The proposed technique combines osteotomy and ring external fixation with advanced computer-assisted correction methods, aiming to improve the reliability of measuring and fixing this deformity.

Background: Displaced diaphyseal fractures can be reduced using the push-pull technique, wherein a plate is affixed to the distal fragment of the fracture, a post screw is placed proximal to the plate, and a lamina spreader creates distraction. This study evaluated the load to failure and mechanism of failure of bicortical and unicortical post screws during reduction.

Materials And Methods: Four matched pairs of cadaver legs were subjected to a 2-cm oblique osteotomy simulating a displaced, oblique diaphyseal fracture.

Case: An 85-year-old woman with a history of bladder mesh sling placement sustained a pelvic fracture and extraperitoneal bladder rupture after a ground-level fall. The patient underwent cystorrhaphy and percutaneous anterior column screw placement. Free air was identified on abdominal computed tomography scan on postoperative day 5.

This study investigated predictive factors for return to play among National Football League athletes after operative treatment of ankle fractures and the impacts of these injuries on career longevity and player performance. Athletes who underwent surgery to repair ankle fractures from the 2013 to 2017 seasons were identified from injury reserve lists and press releases. Demographics and season metrics were collected before and after the injury.

Postoperative venous thromboembolism is a major adverse event associated with orthopaedic surgery. With the addition of perioperative anticoagulation and antiplatelet therapy, the rates of symptomatic venous thromboembolism have dropped to 1% to 3%, and as such, practicing orthopaedic surgeons must be familiar with these medications, including aspirin, heparin, or warfarin, and the use of direct oral anticoagulants (DOACs). DOACs are increasingly being prescribed due to their predictable pharmacokinetics and increased convenience, as they do not require routine monitoring, and 1% to 2% of the general population is currently anticoagulated.

Introduction: Chronic global pelvic instability can be due to many different etiologies with infection being an uncommon cause. We present a case of chronic global pelvis instability secondary to osteomyelitis involving both the anterior and posterior ring, a rare and challenging problem with no standard treatment.

Case Presentation: A 57-year-old female with a history of intravenous drug use presented with global pelvis instability in the setting of pubic symphysis and posterior sacroiliac osteomyelitis with multiple-associated abscesses.

On May 7, 2020, the Coalition for Physician Accountability's released "Medical Students in the Class of 2021: Moving Across Institutions for Post Graduate Training," which comprises official recommendations on keeping programs and medical students safe during the upcoming match cycle with the challenges posed by COVID-19. In these recommendations, away rotations are discouraged, and all programs are compelled to commit to virtual interviews. Unlike employers and applicants in other industries, orthopaedic residency/fellowship programs and candidates seeking those positions have not routinely conducted virtual interviews.

Case: A 65-year-old man previously treated by intramedullary nailing for a left tibial shaft fracture presented 6 years later with an open refracture of his left tibia after a motorcycle accident. Treatment required extraction of the bent nail before revision nailing.

Conclusions: Extraction of deformed intramedullary devices is a skill that will continue to be demanded of orthopaedic surgeons.

On October 26, 2017, US president, Donald J. Trump, declared the opioid epidemic a national public health emergency. This declaration opened the door to government funding for programs geared toward studying and treating opioid addiction; however, part of the responsibility to slow the epidemic falls on physicians.

Background: The predictors of erroneous publication reporting among orthopaedic surgery residency applicants have not been established.

Methods: A retrospective analysis of the reported scholarly activity of candidates who applied to our orthopaedic surgery department for a first-year residency position in 2017 was conducted to determine the incidence of scientific publication misrepresentation and analyze its association with pre-residency criteria.

Results: Out of 510 candidates, 264 (51.

Evaluation of coagulation is vital in the care of the orthopaedic patients, particularly in the subspecialties of trauma, spine, arthroplasty, and revision surgery resulting from blood loss and coagulopathies. Although conventional tests (prothrombin time/international normalized ratio, activated partial thromboplastin time, platelet count, and fibrinogen) are most commonly used, others like thromboelastography (TEG) are also available to the orthopaedic surgeons. TEG is a blood test developed in the 1950s, which provides a snapshot of a patient's coagulation profile by evaluating clot formation and lysis.

Introduction: The impact of the interview date on matching in orthopaedic surgery residency is unknown.

Materials And Methods: A retrospective review of interviewed applicants for a first-year orthopaedic surgery residency was conducted to determine the likelihood of matching based on being interviewed early versus late at our program. The United States Medical Licensing Examination (USMLE) scores were compared between early and late interviewees.

Background: Cervical injury can be associated with vertebral artery injury. This study was performed to determine the impact of computed tomography (CT) angiography of the head and neck on planning treatment of cervical spine fracture, if these tests were ordered appropriately, and to estimate cost and associated exposure to radiation and contrast medium.

Methods: This retrospective review included all patients who underwent CT of the cervical spine and CT angiography of the head and neck from January 2010 to August 2011 at one institution.
