Hand surgery demands precise exposure in a small surgical field. I have devised a simple, economical stay suture retractor to facilitate skin retraction.
We compared, histologically and biochemically, the effects of blood pretreatment vs. no pretreatment on the ingrowth of scar into subcutaneously implanted blocks of Proplast in rats. No significant differences were found.
The effects of Proplast implants on the soft tissues of rats were studied. The effects from Proplast implants which had been impregnated with blood, plasma, or saline were compared to the effects from implants which had received no pretreatment. No significant differences were found.
