Background: Pelvic fractures (PF) with concomitant injuries are on the rise due to an increase of high-energy trauma. Increase of the elderly population with age related comorbidities further complicates the management. Abdominal organ injuries are kindred with PF due to the proximity to pelvic bones.

Hydroxyapatite (HA) powder was characterized before and after plasma spraying using infrared spectroscopy and thermoanalytical techniques. Structural changes were observed from the infrared spectra for the plasma-sprayed powder. These changes involved dehydroxylation and misoriented hydroxyl ions with different configurations.

This is the patient population the author selected, yet little published information is available. Given that in Canada stroke carries the third highest rate of mortality and the highest risk of morbidity there is a role for an advanced practice nurse to develop and deliver a comprehensive stroke education program for this population.

Because of the wide range of ions and valences which this simple structure can accommodate, the perovskites lend themselves to chemical tailoring. It is relatively simple to synthesize perovskites because of the flexibility of the structure to diverse chemistry.
