The ACL is the primary restraint to anterior tibial translation and also plays a role in rotary stability

It is composed of two bundles, named based on their tibial insertions:
โœฏ Anteromedial
โœฏ Posterolateral

What structure separates the femoral insertions of the two bundles?
AM bundle:
โœฏ Tightest in Flexion
โœฏ Resists anterior tibial translation
โœฏ Tested by Lachman's/Anterior Drawer

PL bundle:
โœฏ Tightest in Extension
โœฏ Rotatory Restraint
โœฏ Tested by Pivot Shift

The bifurcate ridge separates the femoral insertions of the AM and PL bundles.

An in-depth review of Clavicle Fractures.

If you're interested in orthopedics you won't want to miss this one!

๐Ÿฆดโš’๏ธ๐Ÿงต๐Ÿ‘‡
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).
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.

An in-depth review of intertrochanteric and subtrochanteric hip fractures.

If you're interested in orthopedics you won't want to miss this one!

๐Ÿฆดโš’๏ธ๐Ÿงต๐Ÿ‘‡
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.

An in-depth review of Ankle Fractures.

If you're interested in orthopedics you'll definitely want to check this review out!

๐Ÿฆดโš’๏ธ๐Ÿงต๐Ÿ‘‡
The ankle is a complex hinge joint comprised of the tibial plafond, talar dome, and distal fibula.

Ankle fractures most commonly occur in elderly females, with roughly 70% being isolated malleolar, 20% being bimalleolar, and 5-10% being trimalleolar. (1)
When first examining a patient with an ankle injury, you can utilize the Ottawa Ankle Rules to determine if you should x-ray the patient.

An in-depth review of pediatric femoral shaft fractures.

If you're interested in orthopedics or pediatrics you'll definitely want to check this review out!

1/10
Pediatric femoral shaft (PFS) fractures constitute a small portion of pediatric fractures roughly 1-2% with a bimodal age distribution

Most common causes:
โœฏ Toddlers: falls
โœฏ Teenage/adolescent: MVA
In children younger than walking age child abuse must be suspected. As high as 80% of PFS fractures in this age group are due to child abuse.

In the toddler age group as high as 25% of PFS fractures are due to child abuse, so it must be ruled out.

So before continuing, I will try to...
- keep everything here in this thread
- share what I snippets I can
- add a number to keep tweets in some order
- respond where possible (but am also engaging in the conference spaces)
- link to papers when I can /2
Now a bunch of # in case relevant to these folks: #MedTwitter #Science #anzbms #biology #pharmatwitter #ortho #rheum #immunology

A review of patellar maltracking and lateral retinacular releases in primary TKA.

1/ Image
Patellar maltracking is the most common complication of primary TKA.

The dynamic forces affecting patellar tracking are represented by the Q-angle, formed by a line from the ASIS to the patella and from the tibial tubercle to the patella. A normal Q-angle is between 12-20ยฐ.

2/ Image
The static transverse stabilizers of the patella include the medial/lateral retinaculum and medial/lateral patellofemoral ligaments.

The dynamic transverse stabilizers include the IT band and vastus medialis/lateralis.

OK! Here goes nothing. My first ever #tweetorial on the Coordinated Interview Release process for #Match2021.

This will be broken up into five parts:
1) What
2) Why
3) Who
4) How
5) Alternatives

Starting with WHAT. What is a coordinated interview release?

A coordinated interview release ๐Ÿ“จ is when numerous residency programs (ideally all programs*) agree to send out their interview invites on the same pre-determined day (or time frame) to applicants.
2.5/
*It's important to note that programs are constrained by factors out of their control โ€“ especially this year with #COVID19 & the coordinated release process being new for most specialties. Those who could not participate this year should in no way be viewed negatively.๐Ÿ†—!!

Meniscus injury: a complete review.

1/15
@MedTweetorials @RosenelliEM
#MedEd #OrthoTwitter #Tweetorials
The meniscus function is two-fold. It increases stability by deepening the tibial surface and it aids in force transmission by increasing the contact area to spread force over a larger surface area. The meniscus is responsible for 50% of load transmission across the knee. (1)

2/
The lateral meniscus has a more circular shape than the C-shaped medial meniscus. The lateral meniscus covers a larger portion of the articular surface and is also more mobile than the medial meniscus. The medial meniscus is relatively immobile and is attached to the MCL.

Interesting #Ortho tidbit. SHOULDER PAIN
You're over 40, you go to the doc because your #shoulder hurts. You did NOT have an injury. Many will be sent for an MRI.... 1/?
Bear in mind ... You have a very significant chance that a rotator cuff "abnormality" will be found. Those abnormalities will sound scary .... Partial rotator cuff tears, full rotator cuff tears, and labral tears. 2/?
These can be very alarming to many people... the word "tear" implies you're damaged and therefore something must be wrong -- and perhaps you're thinking it must be fixed. 3/?
