Current Advancements in Ankle Arthrodiastasis.

Ankle arthrodiastasis offers an option for patients with end-stage primary or posttraumatic ankle osteoarthritis. The process allows for a joint salvage procedure as an alternative to arthrodesis or ankle implant arthroplasty. The distraction within the joint optimizes the intraarticular environment to permit equilibration of hydrostatic pressure, promoting subchondral morphoangiogenesis, and decreases subchondral sclerosis, thereby mitigating pain.

Oviposition restraint and developmental alterations in the ectoparasitic wasp, Nasonia vitripennis, when utilizing puparia resulting from different size maggot masses of Lucilia illustris, Protophormia terraenovae, and Sarcophaga bullata.

Adult females of the ectoparasitoid Nasonia vitripennis (Walker) are capable of distinguishing between hosts of different quality, and then correspondingly adjust clutch sizes and sex ratios of the offspring. In this study, we examined whether the size of the maggot mass, and presumably the developmental temperature, influenced the suitability of the resulting fly pupal and pharate adult stages as hosts for N. vitripennis.
