The Effect of Mitek Anchor Insertion Angle to Attachment of FDP Avulsion InjuriesFrom the Orthopaedic Research Laboratories, University of New South Wales, Prince of Wales Hospital, Randwick, NSW, Australia and the Sydney Hand Unit, St Lukes Hospital, Potts Point, NSW, Australia Correspondence: Prof William R. Walsh, PhD, Orthopaedic Research Laboratory, Prince of Wales Hospital, High Street, Randwick, NSW 2031, Australia. Tel.: +612 9382 2657; fax: +612 9382 2660. E-mail: W.Walsh{at}unsw.edu.au Flexor digitorum profundus (FDP) tendon avulsions, although uncommon, are not infrequent injuries. A widely accepted method of treating Type 1 FDP avulsions is a pullout suture tied over a button on the nail plate. The external dorsal button is often a source of inconvenience for the patient. Potential risks associated with button use include nail plate deformities, nail fold necrosis and infections tracking along the sutures. The use of small suture anchors provides a satisfactory alternative, because buried fixation avoids these potential complications. This in vitro, biomechanical study examined the influence of the anchor orientation on the properties of the repaired FDP tendon using human cadavers.
