Extinct archosaurs, including many non-avian dinosaurs, exhibit relatively simply shaped condylar regions in their appendicular bones, suggesting potentially large amounts of unpreserved epiphyseal articular cartilage. Extant alligators and birds were used to establish an objective basis for inferences about cartilaginous articular structures in such extinct archosaur clades as non-avian dinosaurs.
What is a Broken Finger Phalanx Fracture? A broken finger also known as a phalanx fracture is a very common hand injury. In people under 30 years old, fingers are usually broken during sports; and for people between years old, fingers are typically broken from a machine or work related accident, and in people older than 70, its usually broken during a fall.
Lets quickly review the anatomy of our hand. Our wrist bones are called carpal bones we have 8our hand bones are called metacarpals we have 5, one for each fingerand our finger bones are called phalanx bones.
Each finger has 3 phalanx bones. The first bone in your finger is called the proximal phalanx, the middle finger bone is called the middle phalanx, and the finger tip bone is called the distal phalanx. In this talk we will look at the diagnosis and treatment of a broken proximal or middle phalanx.
A broken distal phalanx the tip of the finger usually occurs when your finger gets crushed like caught in a door and this is called a "Tuft Fracture" and is discussed in a separate section because its so common see talk.
How is a Broken Finger Phalanx Fracture diagnosed? A broken finger is suspected when someone reports injuring their finger and Slipped capital femoral epiphysis essay experiencing significant pain and swelling. A finger bent out of place is a pretty good indication that the finger is either broken or dislocated or both.
The inability to bend your finger due to pain is also suggestive of a break.
If your doctor suspects a broken finger, the next step is to get an x-ray. An x-ray of the injured finger is a good way to diagnose a broken finger, and usually its the only tested needed for diagnosis. X-rays of the broken finger are then used to guide treatment.
How is a Broken Finger Phalanx Fracture treated? All broken fingers are not equal, some need surgery and some just need buddy tape. So how do doctors decide? The first step is to look at the pattern of the break. Looking at the x-rays doctors determine 1 if it enters into the joint aka knuckle, where the two finger bones come together and allow your finger to bend2 if its broken in multiple places; 3 if the bone fragments have moved out of position.
A break in the finger bone that stays away from the joint "extra-articular" is usually treated by simply buddy taping it to the neighboring finger for about 3 weeks longer immobilization has an increased risk for causing long-term finger stiffness. Buddy tape works well as long as the broken bone is in normal or near normal alignment this shows that its stable If the bone is broken in only one place and its bent less than 10 degrees and it hasn't shortened or rotated, then its stable.
Buddy tape is great because recruits your neighboring finger as a splint to give protection and stability to the injured finger, while also allowing your finger to move a little bit so that it doesnt get too stiff stiffness is a real concern with finger injuries, more on that later.
However, if the finger is broken into multiple pieces or if the crack in the bone enters one of the knuckle joints "intra-articular" or if the bone fragment has moved significantly out of position, then surgery is often recommended. If the finger bone shortens more than 2 milimeters or is bent over 10 degrees, an "extensor lag" will develop, which means that you cannot fully straighten that finger the biomechanics are changed.
Breaks that go into the finger joint called "Condyle Fractures" are unstable even if it looks like a tiny hairline crack "nondisplaced". They typically require surgery. A "Pilon Fracture" at the base of the middle phalanx is another common break that involves the joint, its usually accompanied by cartilage injury, and frequently needs surgery to restore the joint surface.
The goal of surgery is to get the broken bone to normal alignment, and then hold the bone in alignment while it heals. Surgery typically involves using a few tiny screws, a small metal plate, or two pins to hold the broken bone fragments in good alignment.
The metal gives extra stability while the bone heals. Many x-ray pictures are taken during surgery to ensure that the bone is straight. If screws are used, they stay in the bone forever while pins are removed after weeks.Written EPE Membership – EPE Written is a subscription that allows you to access a large selection of EPE content.

The Slipped Capitol Femoral Epiphysis involves some, typically blunt, force that causes a shift in the growth plate at the femoral head/neck junction, which negates the head/neck offset (at least this is . In regard to the symptomatology group and the slip degree versus chondrolysis, the p value was not statistically significant in both analyses, p = and p = arteensevilla.com analyzing the nonoperative treatment of slipped capital femoral epiphysis and chondrolysis, we conclude that employment of the treatment revealed that the method.
