Anatomy
This ligament spans from the base of the 2nd metatarsal to the medial cuneiform in the absence of a ligament between the 1st and 2nd metatarsal bases.
What is the Lisfranc ligament?
Metatarsal fractures involving this plane of angulation greater than 10 degrees are generally treated surgically.
What is the sagittal plane?
This concerning finding on physical exam may prompt checking compartment pressures and potential need for urgent fasciotomy.
What is new numbness, coolness or increasing pain/swelling?
This advanced imaging modality may be obtained for occult stress fractures not visible on initial radiographs.
What is a bone scan?
This type of fixation is commonly used for displaced proximal 5th metatarsal fractures through a percutaneous approach.
What is an intramedullary screw?
This area of the 5th metatarsal has been described as a potential watershed region with poor vascularity that may impair fracture healing.
What is the metaphyseal-diaphyseal junction?
Injuries are sub-classified into zones based on the location - Zone 1 involves the tuberosity or styloid, while Zones 2 and 3 are in this region of the 5th metatarsal.
What is the metaphyseal-diaphyseal junction/Jones region?
Patients with this classic triad of factors are at increased risk for developing metatarsal stress fractures.
What is the female athlete triad (amenorrhea, low bone mass, poor nutrition)?
Intra-articular extension and concomitant Lisfranc injuries are best evaluated by this imaging study.
What is a CT scan?
This form of fixation may be employed for comminuted first metatarsal fractures to maintain length of the first ray.
What is external fixation?
