Game Schedules and Rate of Concussions in the National Football League.

Background: Concussion prevention in the National Football League (NFL) is an important priority for player safety. The NFL now has modified game schedules, and one concern is that unconventional game schedules, such as a shortened rest period due to playing on a Thursday rather than during the weekend, may lead to an increased risk of injuries.

Hypothesis: Unconventional game schedules in the NFL are associated with an increased rate of concussion.

A Scaphoid Stress Fracture in a Female Collegiate-Level Shot-Putter and Review of the Literature.

Scaphoid stress fractures are rare injuries that have been described in young, high-level athletes who exhibit repetitive loading with the wrist in extension. We present a case of an occult scaphoid stress fracture in a 22-year-old female Division I collegiate shot-putter. She was successfully treated with immobilization in a thumb spica splint for 6 weeks.

The accuracy of ultrasound-guided and palpation-guided peroneal tendon sheath injections.

Objective: The aim of this study was to describe and to validate an ultrasound-guided peroneal tendon sheath (PTS) injection technique and to compare the accuracy of ultrasound-guided vs. palpation-guided PTS injections in a cadaveric model.

Design: Twenty cadaveric lower limbs were injected with and without ultrasound guidance, using a different color of liquid latex for each injection technique.

Accuracy of ultrasound-guided and palpation-guided knee injections by an experienced and less-experienced injector using a superolateral approach: a cadaveric study.

Objectives: To evaluate the accuracy of ultrasound (US)-guided and palpation-guided knee injections by an experienced and a less-experienced clinician with use of a superolateral approach.

Design: Single-blinded, prospective study.

Setting: Academic institution procedural skills laboratory.
