Intrathecal chloroprocaine or hyperbaric prilocaine for ambulatory knee surgery? A prospective randomized study.

Purpose: The aim of this study was to compare intrathecal 1% chloroprocaine with 2% hyperbaric prilocaine in the setting of ambulatory knee arthroscopy. We hypothesized that complete resolution of the sensory block was faster with chloroprocaine.

Methods: Eighty patients scheduled for knee arthroscopy were included in this prospective randomized double-blind study.

[Surgical treatment of fractures of the radius neck in children using the Métaizeau technic].

Fractures of the radial neck in children must be reduced when the angular displacement is superior to 30 degrees. Given that orthopaedic reduction is difficult, internal fixation using closed intramedullary pinning, as described by Métaizeau in 1980, seems to be an elegant solution which preserves the vascularisation of the physis. The authors report their experience with this technique, which has been used to treat fifteen patients, with a mean age of nine years, between 1983 and 1996.
