♀️Most women who get waved off in perimenopause are not dramatic. A lot of clinicians were barely taught this. In one survey, only about 7% of medical residents felt prepared to manage menopause. About 20% got no lectures on it at all. If you were told it was “just stress,” that can be a training gap. Not a personality flaw.

Fantastic news for Clarke as he probably went though the beginning protocol stages
Brandt Clarke is out on the ice. Good sign that he’s not in a red jersey #GoKingsGo

Cooley is deemed week to week on IR which fits more of the MCL sprain window depending on the grade Good news that the ACL is safe Could be some sort of ankle sprain too but as mentioned it did not seem too bad of a mechanism on the ankle
Devin Cooley of the Flames left the game with a LBI after the collision seen below His left leg extends out and gets caught in an awkward position and he collapses on top of it First glance had me thinking more adductor strain but the way he falls on the leg could mean more knee ligament (MCL/ACL) or meniscus injury It does seem to get too stuck underneath him but it hard to tell Could be looking at a more than a day-to-day situation but hoping that is wrong

The baseball season is over and with a pending lockout an interesting piece about prolonged training interruptions came across my eyes Could be useful for the general population as well⬇️ A review in The American Journal of Sports Medicine found that a complete stop in training costs up to 10% of fitness for each week of inactivity. Aerobic and strength endurance fade faster than speed and maximal strength. Detraining reduces VO2 max, blood volume, stroke volume and insulin sensitivity, and it raises body-fat percentage After four weeks of inactivity, fast-twitch fibres start converting to slow-twitch, and athletes with more muscle to begin with lose it faster, and the loss of flexibility that follows raises the risk of injury The 2020 shutdown is the closest thing we have to a natural experiment In Swiss elite athletes had training times drop which interesting also heightened anxiety, depression, and insomnia Most of these effects returned to baseline once restrictions ended and could be attributed to financial concerns too The moral for you is to NEVER STOP MOVING

Brandt Clarke down and out after this dirty hit Will vertical’s he checked for a concussion and neck injury through the protocol Common mechanism for a potential AC joint sprain/separation but Clarke seems to reach for the jaw/head first so maybe less likely

Spitting up blood or “something like that”????
Christian Watson on what, exactly, happened tonight. He wanted to keep playing immediately, but he was coughing up blood on sideline. Tests checked out at hospital. Just a broken rib. Never stopped saying he’d return, but didn’t know until leaving hospital. Psycho stuff.

Brock Faber has been reportedly cleared to begin skating again in a couple of days after this play left him with a fractured skull about a month ago Him being cleared to skate tells us this was likely an uncomplicated fracture and concussion symptoms may have resolved which is fantastic news There is still a long road for Faber to return to fully playing, likely at the very least a couple more months to begin ramping up any sort of contact Will be interesting to see other potential precautions taken for Faber such as equipment modifications The skull heals well and the reinjury risk lies more in brain injury versus fracturing it again. It is important to note that feeling better does NOT always equal fully recovered, especially in this case

Warren Foegele left the game with assistance last night after knee on knee contact Lauzon’s knee seemed to strike Foegele’s knee on the outside more and causing that valgus stress that is seen very commonly in MCL sprains/tears The knee did not seem to give as much as guys like Marchenko the other day which is promising but cannot rule out any ligament or meniscus injury of the knee Any time there is a big blow like this it is important to rule out a tibial plateau fracture (pictured below) among other fractures, so X-Rays were likely taken A simple contusion is a diagnosis of exclusion so we will wait to see Foegele’s timeline

Noel Acciari left the game after this collision but later returned which is good news It seems the injury came from the knee to the head in what we call an axial loading pattern injury This mechanism in general is concerning for a cervical (neck bone) fracture of spinal cord injury; this definitely did not happen as he returned but is just a general tidbit It can also cause concussions very easily which is likely why Acciari got checked out Wonder if he will deal with some stiffness or neck strain symptoms later on

Another angle of Cooley that leads to more knee speculation versus groin Ankle could even be involved but it didn’t seem to get trapped too

Zach Hyman placed on IR from this hit and reportedly has a “stiff neck” It still could be likely that this is treated as a concussion with a neck injury of some sorts involved I am sure they looked for signs of unstable neck injury and red flag concussion The neck may have undergone a strain of some sorts that has been causing the stiffness mentioned Hyman could just go through concussion protocol at the same time he is healing the neck up

Likely some sort of grade 1 MCL sprain for Marchenko given the mechanism and timeline Given at the time of injury his skate was not stuck in the ice could have prevented an ACL injury with it Grade 1 injuries have returned to play in as little as 10 days but Kirill will probably wait till he is pain free and feels stable
🚨 A group of Leafs fans bumped into Kirill Marchenko at the Calgary airport today, where he told them he was “flying back home today” and will be back in “two weeks.” As of now, no official confirmation has been made by the Leafs (should know more tomorrow) 📸: @Alwaysbardown1 #leafs

Jack Hughes⬇️
Chipped teeth are practically a hockey rite of passage as Jack Hughes here would say 🏒🦷 But here’s the anatomy + physiology behind how they get fixed. 🦷 What Happens When a Tooth Chips? Teeth have layers: 1.Enamel – Hard, mineralized outer shell (no nerves, no blood supply) 2.Dentin – Softer layer underneath, contains microscopic tubules connected to nerves 3.Pulp – Central core with blood vessels and nerves If the chip is: •Enamel only → cosmetic issue, usually painless •Into dentin → sensitivity to air/cold (fluid shifts in dentinal tubules stimulate pulp nerves) •Into pulp → bleeding, significant pain, infection risk 🏒 How Does It Get Fixed? 1️⃣ Evaluation Team dentist checks depth of fracture and maybe an X-ray to assess pulp involvement. 2️⃣ Enamel/Dentin Chip Most common in hockey. •Smoothed or rebuilt with composite resin bonding •Resin chemically bonds to enamel via acid etching •Light-cured to harden Function restored immediately. 3️⃣ If Pulp Is Exposed •Root canal: Remove inflamed pulp, disinfect canal, fill with gutta-percha •Crown may be placed later for structural strength 🧠 Physiology Pearl Dentin hypersensitivity happens because exposed dentinal tubules allow fluid movement which triggers mechanoreceptors in the pulp (hydrodynamic theory).

Sam Steel of the Stars received an “injection as part of his treatment” What does that mean? It could mean several things Most often, this means a corticosteroid injection. Corticosteroid injections switches off inflammatory genes which reduces pain and swelling. The steroid takes effect over a few days, and a "steroid flare" (more pain for 24–48 hours) can happen first. I have been giving a ton of these on my current school rotation The trade-off is that inflammation is part of normal healing, so suppressing it may in theory slow repair. 🚨The steroid also does not reverse structural damage! An injection does not repair tissue. Other possibilities are platelet-rich plasma (PRP) or an anesthetic-only diagnostic injection. Diagnostic anesthetic injection involves numbing a specific spot, such as the hip joint, helps identify the pain source. If pain goes away, the joint is the likely source. PRP is when the player's own concentrated platelets are injected to try to stimulate healing. It has been tried for adductor injuries that don't respond to rehab, but evidence is limited (@DrJesseMorse is a good follow for this stuff) What does this tell us in Steel’s case? Steroid injection directly into a fresh muscle tear is controversial, so this injection 2 days after an injury points to something to more than a simple tear Bursitis or tendon irritation respond well to injections, and can lead to a return of play in as little as a week Reviews note that a midseason corticosteroid injection may be considered specifically to speed return to play for players with recurrent pain. Steele had a hip/groin issue this March, so this is very much in play Overall, a quick return (days to about 2 weeks) suggests the injection was used to manage pain or inflammation in a minor or chronic problem so he can keep playing. A longer absence suggests the injection was diagnostic or supportive alongside a real structural injury.
