How can one reduce the risk of knee #osteoarthritis?
1. Knee osteoarthritis (OA) causes knee pain. It limits mobility, hampers physical activity and contributes to sedentary lifestyle, which in turn, increases the risk of obesity, diabetes, hypertension, heart attack and stroke.

The second wires is used to hold and correct the radial tilt of the styloid fragment. It is applied from the radial direction.

2/When it comes to brachial plexus injuries, the most important distinction to make is whether it is a pre or post ganglionic injury. Pre ganglionic injuries are nerve root avulsions from the spinal cord and cannot be repaired, while most post ganglionic injuries can be repaired
3/It’s like repairing a house. If there’s a structural flaw at the beginning, before you’ve even built it, you won’t even try to build it, you’ll just scrap the design (preganglionic). But if there’s damage after the house is built, you can salvage it w/repair (postganglionic)

2/Brachial plexus is how the cervical nerves reach the arm. In the coronal plane, it looks like a slide, guiding nerves downward. Bc nerves are traveling laterally, sagittal MRI plane is our plane of choice to cut the nerves in cross section & see down the barrel of the nerves
3/But it’s more than a slide, it’s a complex highway, w/nerves joining & dividing—like highway off ramps & on ramps. If you want to know more about this intrinsic anatomy, see my first brachial plexus tweetorial here:

2/Everyone has a mnemonic to remember brachial plexus anatomy. I’m a radiologist, so I remember one about Rad Techs. But just remembering the names & their order isn’t enough. That is just the starting point--let’s really understand it
3/From the mnemonic, we start with the roots—the cervical nerve roots. I remember which roots make up the brachial plexus by remembering that it supplies the hand. You have 5 fingers on your hand so we start with C5 & we take 5 nerve roots (C5-T1).

2/A is for alignment. Normal spinal alignment is perfectly in balance, resulting in the minimal energy needed for erect posture. Even subtle changes in alignment need compensatory changes to maintain posture, resulting in more work/energy expenditure & pain.
3/The goals for alignment on imaging: (1) look for unstable injuries & (2) look for malalignment that causes early degenerative change. Abnormal motion causes spinal elements to abnormally move against each other, like grinding teeth wears down teeth—this wears down the spine

Most tibial pilon fractures result from high-energy axial loading through the talus.
They are also commonly referred to as Tibial Plafond fractures. The tibial plafond is the distal articular surface of the tibia, which gained the name from its French meaning, "ceiling".
They are also commonly referred to as Tibial Plafond fractures. The tibial plafond is the distal articular surface of the tibia, which gained the name from its French meaning, "ceiling".
The term tibial pilon was first used by Étienne Destot in 1911 to describe the interaction of the distal tibia and talus during axial loading.
Pilon is the French term for "pestle".
The term was later adopted as a term for vertical impaction fractures of the distal tibia.

First off, what is an eponym fracture?
Eponymous: of, relating to, or being the person or thing for whom or which something is named.
Eponym fractures are named based on the first person to describe them (e.g. Holstein-Lewis) or by an activity (e.g. Chauffer's)

The humeral shaft is defined as the area distal to the surgical neck and proximal to the epicondyles.
The commonality of fracture is:
Middle ⅓ > Proximal ⅓ > Distal ⅓ shaft
The deforming forces of humeral shaft fractures usually result in what type of deformity?
The commonality of fracture is:
Middle ⅓ > Proximal ⅓ > Distal ⅓ shaft
The deforming forces of humeral shaft fractures usually result in what type of deformity?
Due to the muscular pull of the deltoid on the proximal fragment and medial/superior pull on the distal fragment, humeral shaft fractures tend to develop varus angulation.
Humeral shaft fractures are forgiving, and modest angulation can be overcome by the shoulders' large ROM.

Clavicle fractures are typically the result of a fall onto the shoulder and are one of the most common fractures in children.
They may also occur from direct trauma, seizures, or a fall onto an outstretched hand (FOOSH).
They may also occur from direct trauma, seizures, or a fall onto an outstretched hand (FOOSH).
The clavicle serves as the connection between the UE and axial skeleton.
It is the first bone to ossify and the last to fuse. It is S-shaped and widest medially.
Most fractures occur in the middle 1/3rd, roughly 80%, which is the thinnest segment.

Basicervical femoral neck, intertrochanteric (IT), and subtrochanteric (ST) hip fractures are different from femoral neck fractures in that they are extracapsular.
Extracapsular fractures, unlike intracapsular femoral neck fx, have a low likelihood of blood supply disruption/AVN

Anatomy:
The calcar femorale is an extension of cortical bone from the proximal shaft to the posteromedial femoral neck. It aids in weight distribution from the hip to the proximal femoral shaft.
The subtrochanteric region extends 5 cm below the lesser trochanter.
