Case Reports
Definitive treatment of bilateral acetabular and pelvic ring injuries using external fixation.
Bilateral pelvic ring and acetabular fractures are rare injuries. The optimal treatment of these patients and their outcomes remain largely unknown. We present a three year follow up of a case of bilateral posterior pelvic ring injuries and acetabular fractures treated successfully with limited internal fixation and external fixation.

Randomized, controlled study in a laboratory setting. Blinded observations/assessment of study outcomes. ⋯ In this commonly used rabbit posterolateral fusion model, Mastergraft(®) Strip with BMA in an autograft extender mode produces biomechanical and radiographic results similar to autograft fusion alone.

Numerous studies have examined the elution characteristics and the effects of antibiotics from bone cement. this study seeks to determine the effect that surface area and volume have on the elution characteristics and bioavailability of tobramycin and vancomycin when mixed in polymethylmethacralate (PMMA) bone cement in various combinations. It also investigates the mechanical properties of antibiotic-impregnated bone cement and its relationship to surface area and volume. ⋯ This study advanced our overall understanding of the elution characteristics and biomechanics of PMMA bone cement impregnated with tobramycin and vancomycin.

Peripheral nerve blocks (PNB) are a common adjuvant for anesthesia. There is little orthopedic literature regarding the incidence of neurogenic complaints and quality of pain control. ⋯ Cohort study type III.

Randomized, controlled study in a laboratory setting. Blinded observations/assessment of study outcomes. ⋯ In a rabbit posterolateral fusion model, Progenix(®) DBM Putty in an autograft extender or enhancer mode produced manual palpation and radiographic fusion rates equivalent or slightly better than autograft fusion (3 cc) alone. the results from the two autograft groups demonstrate the need for adequate graft volume to achieve high radiographic and mechanical fusion rates.
