Case Reports
Continuous thoracic paravertebral nerve block in a working anesthesia resident-when opioids are not an option.
Multiple unilateral rib fractures can cause significant pain and morbidity. Continuous nerve block catheters are often maintained while inpatient, and patients are discharged with oral analgesics. However, in many institutions, this dynamic is changing and patients are being managed effectively with outpatient catheters. ⋯ On post-injury day 18, he was able to discontinue the catheter and there were no associated complications. We report a unique case of a patient with multiple rib fractures who was not able to be exposed to potential side effects of opioids. The use of a continuous thoracic paravertebral nerve in an outpatient setting allowed a faster return to function with no adverse events.

Lower limb and lower back injuries are prevalent within the New Zealand (NZ) Army: independently collected data shows these to be most prevalent, with on average 10% of military personnel affected by such an injury at any time. To improve the quality and appropriateness of footwear, it is essential that normative foot anthropometric data is collected from NZ Army personnel. ⋯ It was found that the NZ Army personnel had notable differences in feet anthropometry compared to an exemplary model for the NZ general population, specifically in terms of arch height. It was also found that a substantial proportion (approximately 50%) of personnel tested could not be provided with a boot that fit (mainly Maori and Pacific Island soldiers) because of a limited width range of the currently issued boot.

The purpose of this study was to review incidence of stress fractures in military and athlete populations and identify factors explaining causes and differences in the incidence among genders. ⋯ Factors possibly explaining why females are more susceptible to stress fractures include bone anatomy, lower aerobic capacity, smaller muscle, and poor diet. However, both female recruits and athletes with normal weight and bone health are less likely to develop stress fractures, showing that gender is less important than the overall physical shape/condition.

Case Reports
"HOOAH!" A case of pneumomediastinum in the military training environment; Hamman's sign 71 years later.
A previously healthy 20-year-old male trainee developed chest pain, shortness of breath, and neck pain after repeatedly shouting "Hooah!" during a motivational squad competition. He was found to have developed a pneumomediastinum with soft tissue crepitus of the neck. ⋯ Unique to the military training environment, vigorous shouting, including "Hooah!" as a motivational stimulus, can have barotraumatic consequences. The term "spontaneous" as applied to a pneumomediastinum diagnosis is examined and the auscultatory finding of "Hamman's sign" is reviewed.
