Acromioclavicular Joint Injuries Illustrations

~ Murat Yazici, Turkey ~ Leave a comment

Acromioclavicular joint (AC) injuries are associated with damage to the joint and surrounding structures.

ANATOMY

The acromioclavicular joint, together with the sternoclavicular joint, connects the upper limb to the skeleton.

The support of the acromioclavicular joint is provided by the ligament and muscle surrounding the joint. The capsule surrounding the acromioclavicular joint is strengthened by the acromioclavicular ligaments. The joints are acromioclavicular ligaments that provide horizontal stability.

The coracoclavicular ligaments consist of two parts, the lateral trapezoid, and the medial conoid, and connect the distal lower clavicle to the coracoid process of the scapula. The coracoclavicular ligament is the main stabilizing ligament of the upper limb.

Acromioclavicular joint injuries occur at all ages, but are most common in the 20-40 year age group, 5x times more common in men than women. It is a common contact sports injury in young male athletes (1).

There are two main mechanisms of acromioclavicular joint injury; direct and indirect (2). A direct blow or fall to the shoulder results in a superior force on the acromion with restricted clavicular movement in the joint, the acromion is forcibly pushed down and medially relative to the clavicle. It can occur indirectly as a result of a fall on the hand or elbow, causing the humerus to be pushed into the acromion, resulting in lower-grade injuries that typically protect the coracoclavicular ligament.

Imaging can be used to classify acromioclavicular injuries and is the most widely used Rockwood classification.

Rapid Ultrasound for Shock and Hypotension (RUSH) Protocol US Imaging – Illustrations

~ Murat Yazici, Turkey ~ Leave a comment

Patients with hypotension or shock have high mortality rates, and traditional physical exam techniques can be misleading. Diagnosis and initial care must be accurate and prompt to optimize patient care. Ultrasound is ideal for evaluating critically ill patients in shock, and ACEP guidelines now delineate a new category of ultrasound (US)– “resuscitative.” Bedside US allows for direct visualization of pathology and differentiation of shock states (1). The RUSH is one of the most commonly used protocols for this purpose.

The RUSH exam involves a 3-part bedside physiologic assessment simplified as “the pump,” “the tank,” and “the pipes” (2).

Lower Extremity Deep Venous US Imaging – Illustrations

~ Murat Yazici, Turkey ~ Leave a comment

Ultrasound evaluation for deep venous thrombosis (DVT) is one of the 11 core ultrasound applications for emergency physicians as listed in the 2008 American College of Emergency Physicians guidelines (1). Because ultrasound applications started to be implemented into medical school curriculum in many countries, learning basic ultrasound applications as early as possible will benefit medical students and junior residents. In this post, I will share lower extremity venous ultrasound illustrations with you. 

Indications

The clinical indications for performing a lower venous ultrasound examination is the suspicion of a lower extremity DVT in a swollen or discoloured leg. 

Transducer

Select a high-frequency linear transducer, (5-10) MHz transducer since it provides optimal venous copmression and image resolution.

Remember Risk Factors of DVT

  • Age > 60
  • Cancer
  • Central venous catheter/insertion
  • Genetic causes of hypercoagulopaty
  • History of DVT
  • Immobilization
  • Obesity
  • Pregnancy
  • Smoking
  • Trauma or recent surgery
  • Use of birth control pills or hormone replacement therapy

Wells Score for Deep Vein Thrombosis

CriteriaScore
Active cancer(treatment ongoing or within previous 6 months or palliative treatment)

Paralysis, paresis, or recent plaster immobilization or of the lower extremities1
Recently bedridden for 3 days or more or major surgery within the previous 12 weeks requiring general or regional anesthesia1
Localized tenderness along the distribution of the deep venous system1
Entire leg swollen1
Calf swelling > 3cm compared to asymptomatic leg (measuring 10 cm below tibial tuberosity)1
Pitting edema confined to the symptomatic leg1
Non varicose collateral superficial veins1
Previously documented DVT1
Alternative diagnosis at least as likely as DVT1
