Cutting or Round-Bodied Needles for Tendon RepairFrom the Plastic and Reconstructive Surgery, Castle Hill Hospital, and the Department of Biomechanical Engineering, University of Hull, West Yorkshire, UK Correspondence: Mr Wee Leon Lam, Plastic Surgery and Burns Research Unit, School of Biomedical Sciences, University of Bradford, Richmond Road, Bradford BD7 1DP, UK., Tel: +44 1274 235524, Fax: +44 1274 309742; E-mail: weeleon{at}yahoo.com We carried out a biomechanical study comparing tensile strength after using round-bodied or cutting needles for tendon repair. Swine tendons were repaired in three groups: Group 1 core suture repair only; group 2 core and circumferential suture repair; and group 3 isolated circumferential suture repair. The tendons were tested at longitudinal stress to failure at 5 mm/minute. No significant differences were found between the round-bodied and cutting needles in any group. Equal numbers in the core suture repair group failed by suture pullout when comparing cutting and round-bodied needles. We conclude that the choice of needle has no effect on the outcome of tendon repair if there is consistency of surgeons skill and experience.
