Negative pressure wound therapy combined with timed, cyclical instillation (NPWTi) of topical wound solutions has been recently presented as a new adjunctive modality for treating wounds with signs of infection. Normal saline, antiseptics and antimicrobials all have been proposed in scientific and clinical studies as potentially effective when used with NPWTi for treating heavily infected wounds. This is a prospective clinical study of 131 patients with 131 wounds treated with NPWTi using saline between January 2012 and December 2012 in two orthopaedic centres and one surgical wound healing centre in France. Saline was exclusively used. Results were favourable: in 98% of the cases, the wounds could be closed after debridement and following the use of NPWTi. Mean duration of NPWTi was 12·19 days. This does not preclude the need for treating the biofilm appropriately with more active antibacterial products when biofilm has been documented.

The current tendency of microsurgery is heading toward supermicrosurgery and microsurgery assisted by robotics. The aim of this work was to study the feasibility of a free hallux hemipulp transfer with a surgical robot in a cadaveric model. We used a human body. The intervention was realized by a Da Vinci SI® robot (Intuitive Surgical™, Sunnyvale, CA) in two stages: first taking off the medial hallux hemipulp, then transferring the hallux hemipulp to the radial thumb hemipulp. The intervention lasted 1 hour 59 minutes, exclusively with the Da Vinci SI® robot, without any interruption or outside intervention. Despite the absence of sensory feedback and an intervention 25% longer than in conventional microsurgery, we have demonstrated the feasibility of free hallux hemipulp transfer with a surgical robot. In the future, it is likely that the added benefits of the robot (physiological tremor suppression, user-friendly ergonomics, ultraprecise control of the instruments) will make the robot an indispensable tool for the surgeon.
