UMEM Educational Pearls - Orthopedics

Sever's disease also known as calcaneal apophysitis, is the most common cause of heel pain in the young adolescent (ages 8 to 12).

It can be thought of as the Achilles tendon equivalent of Osgood-Schlatter's disease (patellar tendon insertion pain).

It is a non inflammatory chronic repetitive injury.

Commonly seen bilaterally in up to two -thirds of cases.

Patients will complain of activity related pain to the heel.

There may be tenderness and local swelling at the Achilles tendon insertion.

Radiographs are not necessary for acute cases.

Treat with activity modification, heel raise, physical therapy.

Protracted Recovery from Concussion

Age and sex may influence concussion recovery time frame

Methods: 266 adolescent athletes presenting to a sports medicine concussion clinic

Female athletes had a longer recovery course (P=0.002) and required more treatment interventions (p<0.001).

Female athletes were more likely to require academic accommodations (p<0.001), vestibular therapy (P<0.001) and medications (P<0.001).

Be aware that not all concussion patient subgroups with concussions recover in the same manner. Further study is needed to support whether female adolescent athletes require unique management and treatment guidelines.

Quick pearl for those that are trying to complete their holiday shopping.

Mulder's sign is not a sign that there is an extra-terrestial in your ED, But rather a sign that your patient is suffering from a Morton's Neuroma (see pearl from 2012)

Patients will often complain of pain in 3rd and 4th intermetatarsal space and if you can reproduce the pain by compressing the metatarsal heads together then you have a Positive Mulder's sign. Check out the original pearl at https://umem.org/educational_pearls/1684/



Parental Knowledge of pediatric concussion

Sample: Parents of children brought to pediatric hospital or outpatient clinics for evaluation of orthopedic injuries.

Participants scored an average of 18.4 (0-25) on knowledge and 63.1 (15-75) on Attitudes toward concussions.

Safest attitudes were seen in white females. Knowledge increased with income and education levels.

Parents from low income or education levels may benefit from additional education in the ED prior to discharge in addition to providing paper information which may not be read or understood.

Medial elbow pain is common among baseball pitchers and is also seen in other sports including football, javelin and gymnasts.

More than 97% of elbow pain in pitchers is located medially.

The ulnar collateral ligament of the elbow is an important structure in these patients.

While initially primarily seen in professional throwers, these injuries are now being seen in younger athletes.

Initially, patients may only note changes in stamina or strength of throws.

Later, they will note pain during the acceleration and follow through-phase of throwing

Happy Halloween!! 

I hope you have had a safe and fun Halloween. Thank you to all the people that are staffing the EDs on a Saturday Night Halloween.

Prostate-Selective Alpha Antagonists have been tied to Falls and increased risk of fractues in elderly men.  These medications can lead to syncope and hypotension putting patients at increased risk of falls. A recent canadian study showed that at 90 days of use; individuals on alpha antagonists were at increased risk of hospital visits for falls (1.45% vs. 1.28%) or fractures (0.48% vs. 0.41%). There was also an increased risk of  head trauma.

Please warn patients that are on these medications of the risks, so that injuries can be minimized. They should take specific care when changing postural positions, and report episodes of lightheadedness to their PCPs.

A traditional ED practice has been to combine promethazine as an anxiolytic adjunct to morphine for patients with musculoskeletal pain (eg back pain).

However, when compared to morphine alone, this combination does not lead to greater analgesia or decrease anxiety. It does however prolong ED length of stay.

This use of this "pain cocktail" is not recommended

Shoulder Dislocation Reduction

Do you have a chronic dislocated that frequents your ED? Are you interested in teaching them a way to relocate their shoulder without looking like Mel Gibson from Lethal Weapon, https://youtu.be/Igrdi_lhhW4, then the newly described GONAIS method might be what you are looking for.

This technique has the patient grab the top of a chair with the hand on the affected side, and then slowly equating, effectively bringing the hand and arm above their head. Once in the full squat position the patient can step backwards which should reduce the shoulder. If not they can use the opposite hand to apply pressure to push the humerus backward and reduce the location.

Policeman's Heel:

When patient's present complaining of heel pain we often think immediately of plantar fascititis,and heel spurs. If they jumped and landed on the heel with are concerned for calcaneal fracture.  However, a policeman's heel can occur from repetitive bounding of the heel or from landing on it as in a fall or jump.

Policeman's heel has been descirbed as a plantar calcaneal bursitis, inflammation of the sack of fluid (bursa) under the heel bone, or a contusion of the heel bone due to flattening and displacement of the heel fat pad, which leaves a thinner protective layer allowing the bone to get bruised.

Regardless of cause this responds well to NSAIDs, limiting weight bearing, or taping the foot. If the repetitive activity is not reduced this can easily become a chronic cause of heel pain.  A short video showing how to tape the foot can be found at https://youtu.be/nQtkwfJrhXo

Sodium Supplementation and Exercise-Associated Hyponatremia (EAH) during Prolonged Exercise (ultramarathon running)

Weight loss of around 4% body weight (relative to pre race weight) can be anticipated to maintain euhydration in such a prolonged event

Those who become symptomatic with EAH have either gained weight or lost less that 3-4% body weight

Overhydration rather than inadequate supplemental sodium intake is a greater contributor to the development of EAH

There is a suggested link between EAH and rhabdomyolysis. The mechanism remains unknown and it is unclear which condition may augment the other. Further research is needed.

Take home: Avoid overhydration during prolonged exercise to prevent EAH.

Title: Compartment Syndrome - Making the diagnosis

Compartment Syndrome

Compartment syndrome is a diagnosis that needs to be made quickly in order to prevent long term muscle, nerve, and vascular compromise.

Two pieces of information are needed to determine if the patient has compartment syndrome.

  1. The patient's diastolic blood pressure (DBP) value
  2. The pressure value obtained from the compartment of concern (Compartment pressure)

Diastolic Pressure - Compartment pressure < 30 makes the diagnosis of compartment syndrome

So if a diastolic blood pressure is 80 and the compartment pressure is 40 the difference is 40 mmHg and the patient likely does not need a fasciotomy.  The diagnosis can only be 100% onfirmed by a trip to the OR so these values should still be discussed with your local orthopaedist.  When calling them just make sure you know both the DBP and the compartment pressure so that it can be interpreted correctly.

A sports hernia is a painful musculotendinous injury to the medial inguinal floor.

It is the result of repetitive eccentric overload to the abdominal wall stabilizers of the pelvis.

It is common in sports that require sudden changes of direction or intense twisting movements.

Despite the term "hernia" in the title, it is not a true hernia as there is no "herniation" of abdominal contents

http://www.ssorkc.com/wp-content/uploads/2014/09/publagia.gif

Figure description: The upward and oblique pull of the abdominal muscles on the pubis fights against the downward and lateral pull of the adductors on the inferior pubis. This imbalance of forces can lead to injury.

PE: Evaluation of other GU/GYN/other intra-abdominal pathology comes first.

Clinician may note tenderness of the pubic ramus and medial inguinal floor.

Pain is more severe with resisted hip adduction and with resisted sit-up.

Combining these maneuvers (resisted situp while adducting hips) recreates the pathophysiology described above and is a good exam maneuver.

Steroid Use in the treatment of Acute Sciatica

Have you used oral steroids in the treatment of your patient with acute sciatica thought to be secondary to a herniated disk.

Well a recent randomizaed, double-blind, placebo-controlled trial from 2008 to 2013 in a large integrated health care system in Northern California enrolled 269 patients to look at whether steroids improved pain or function. The intervention arm (twice as large as placebo arm) received a tapering 15-day course of oral prednisone (5 days each of 60 mg, 40 mg, and 20 mg; total cumulative dose = 600 mg; n = 181).

In the end there were no differences in surgery rates at 52-week follow-up, and the steroid arm had a modest improvement in function but no improvement in pain. There were also more adverse events at 3-week follow-up in the prednisone group than in the placebo group.

Conclusion: Giving steroids for acute sciatica does not appear to improve the patients pain, only has a modest improvement in function, and was associated with more adverse events. Put another way there was minimal benefit and more harm.
