Cervical Spine CT Can Miss Fractures in American Football Players When Protective Equipment is in Place: A Cadaver Study.

Background: Iatrogenic worsening of spinal injury can result in significant harm to American football players and complicate management when equipment is removed in the acute setting by inexperienced personnel. Spine imaging before removal of protective equipment mitigates this risk. There is no consensus regarding the ideal timing of equipment removal or whether current diagnostic imaging modalities are effective to detect such injuries without equipment removal.

Prediction of Autograft Hamstring Size for Anterior Cruciate Ligament Reconstruction Using MRI.

Background: Hamstring autografts with a diameter of less than 8 mm for ACL reconstruction have an increased risk of failure, but there is no consensus regarding the best method to predict autograft size in ACL reconstruction.

Questions/purposes: (1) What is the relationship between hamstring cross-section on preoperative MRI and intraoperative autograft size? (2) What is the minimum hamstring tendon cross-sectional area on MRI needed to produce an autograft of at least 8 mm at its thickest point?

Methods: This was a retrospective cohort study of 68 patients. We collectively reviewed patients who underwent ACL reconstruction by three separate fellowship-trained surgeons at the Carilion Clinic between April 2010 and July 2013.

Nail and Locking Plate for Periprosthetic Fractures.

The incidence of periprosthetic fractures have been increasing, and in patients with osteopenic bone, high body mass index, or a combination both, they are difficult to treat and pose a high risk for malunion. Previous studies have compared the use of locking plates and intramedullary nails, and have found that each has its own strengthens and drawbacks, but neither is superior in terms of treating periprosthetic fractures. Here, we present the technique and series of patients treated with a combination of a retrograde intramedullary nail and flare-to-flare lateral locking plate without the use of allograft or autograft supplementation.
