Accurate assessment of zone II partial flexor tendon lacerations in the finger is clinically important. Surgical repair is recommended for lacerations of greater than 50% to 60%. Our goal was to evaluate ultrasonographic test characteristics and accuracy in identifying partial flexor tendon lacerations in a cadaveric model. ⋯ Ultrasonography was useful in identifying and characterizing clinically relevant high-grade zone II partial flexor digitorum profundus lacerations in a cadaveric model.

Case Reports
Advantages of Cardiopulmonary Ultrasound in Post-Cardiopulmonary Resuscitation Tension Pneumothorax.
Tension pneumothorax is a life-threatening condition that frequently occurs in the setting of cardiopulmonary resuscitation as a result of positive pressure ventilation and chest compressions. Developing crepitus due to subcutaneous air can severely limit pleural ultrasound (US) views and hinder the diagnosis of pneumothorax by pleural US. Physicians trained in the use of point-of-care US must be familiar with the subcostal cardiac and inferior vena cava views associated with tension pneumothorax. These include a dilated, nondistensible inferior vena cava and hyperdynamic right heart as a result of a reduced preload.

To identify any anatomic barriers to local anesthetic spread between the sciatic nerve (SN) and the posterior femoral cutaneous nerve (PFCN) at the level of the infragluteal crease and to describe a potential technique for an ultrasound (US)-guided subgluteal PFCN block in a cadaveric model. ⋯ The deep investing muscular fascia of the thigh appears to impede the spread of injectate between the SN and PFCN in a most unembalmed cadaver specimens. A US-guided subgluteal PFCN blockade may be a feasible technique to complement an SN block when complete anesthesia of the posterior thigh is required.
