Trick of the Trade: Reducing the metacarpal neck fracture
General principles of fracture reduction involve axially distracting or pulling on a fracture fragment and pushing the piece back into anatomical alignment. This can be seen in the video below (automatically starts at 2:25 for the actual procedure). What if this approach doesn’t work? The fracture fragment remains immobile despite your best efforts.
PV card: Metacarpal fractures
Patients with rotation deformities of the fingers from a metacarpal fracture should be reduced. All fingers should normally point towards the patient’s scaphoid bone.
Metacarpal (MC) fractures are common injuries, which often spark discussions about whether they should be reduced in the ED urgently.
- What are the criteria for acceptable degrees of angulation? Are these criteria different for the MC neck versus shaft?
- Which fractures tend to be unstable and thus require eventual operative repair?
- How should I splint the injury?
Here’s a quick-reference card to help guide your management decisions. These recommendations may vary slightly based on what references you use. You may need to tailor your decisions based on your regional practices.

Poll: How would manage a metacarpal fracture in the ED?
I am in the process of creating a PV card on metacarpal fractures, divided into anatomical areas (base, shaft, neck, head), and am realizing that the EM and orthopedic literature don’t quite agree. Actually they are quite vague on whether reductions should occur in the ED vs orthopedics clinic in the next few days.
- Do you need to close-reduce all angulated fractures in the ED, which are outside of “acceptable” angulations?
- What exactly are “acceptable” angulations? Some sources say that angulations of 10, 20, 30, and 40 degrees are acceptable for MC neck fractures and only 10, 10, 20, and 20 degrees are acceptable for MC shaft fractures. These numbers, though, vary from reference to reference.
Paucis Verbis: Antibiotics and open fractures
Open fractures come in all shapes and sizes. Sometimes fractures create only a small, innocuous-looking puncture through the skin. Other times they look grossly contaminated with organic material and have significant soft tissue injury. The major concern is wound infection. Prophylactic antibiotics are essential in the ED.
Typically antibiotics are first-generation cephalosporins. When do you start adding more coverage with high-dose penicillin or aminoglycosides?
Pearl
Once you have significant soft tissue injury, you are automatically have a Type III fracture and should add an aminoglycoside.

Trick of the Trade: Hip dislocation Part II
As a followup to the blog on the Captain Morgan technique for hip dislocations, I’d like to throw out another similar technique that also does NOT involve climbing up on the gurney.
Trick of the Trade: Captain Morgan technique for hip dislocation
Relocation of a hip joint is often quite a sight to see in the ED. A commonly taught technique is the Allis maneuver (watch the first 45 seconds of the above video from the Medical College of Georgia). It has always seemed a bit precarious to me having someone stand on the patient’s bed.
