Comparison of mechanical properties of polyvinylidene fluoride and polypropylene monofilament sutures used for flexor tendon repair.
نویسندگان
چکیده
We performed an experimental study to evaluate the mechanical properties of polyvinylidene fluoride sutures and to compare their use with that of standard polypropylene sutures for the circumferential, epitendinous suture of a flexor tendon repair. Polyvinylidene fluoride sutures had a smaller suture diameter, a greater knot pull strength and less delayed extension when under creep testing, than polypropylene sutures. Tendons repaired using polyvinylidene fluoride sutures had significantly greater gap and breaking strengths than those repaired using polypropylene sutures.

Mechanical Properties of Polyglycolide-trimethylene Carbonate and Polydioxanone Monofilament Sutures in Vivo Used for Flexor Tendon Repair
INTRODUCTION Braided polyester suture materials have been commonly used for flexor tendon repair in the clinical setting. However, knotted braided polyester lost approximately 50% of its tensile strength according to a study by Trail et al.(1) Accordingly, 4 or 5 throws are needed to prevent slippage for a secure knot, which may result in stitch granuloma. The use of absorbable sutures avoids p...
متن کاملComparison of two different suture-passing techniques with different suture materials and thicknesses: Biomechanical study of flexor tendons for yield points, gap formation and early post-operative status
Objective: The purpose of this study was to evaluate the biomechanical characteristics of two different suture-passing techniques with different suture materials and thicknesses and assess whether they could with stand passive and/or active mobilization in the very early post-operative period. Materials and Method: 192 flexor digitorum profundus communis tendons of similar diameters were obtain...

PURPOSE Little data exist comparing the strength of traditional methods of fixation in a flexor digitorum profundus tendon with the use of a suture anchor. In vitro cyclic testing simulating a passive mobilization protocol was used to compare the repair of a flexor digitorum profundus tendon using a single micro-Mitek anchor (Mitek, Westwood, MA) or a modified Bunnell 2-strand pullout technique...
متن کاملBundles of Spider Silk, Braided into Sutures, Resist Basic Cyclic Tests: Potential Use for Flexor Tendon Repair
Repair success for injuries to the flexor tendon in the hand is often limited by the in vivo behaviour of the suture used for repair. Common problems associated with the choice of suture material include increased risk of infection, foreign body reactions, and inappropriate mechanical responses, particularly decreases in mechanical properties over time. Improved suture materials are therefore n...
متن کاملComparison of Post Operative Early Active and Passive Mobilization of Flexor Tendon in Zone 2
Objectives: Despite numerous studies, having the best outcome is challenging after flexor tendon repairs in zone 2. This study were done to test the hypothesis that immediate postoperative active mobilization will achieve similar outcomes to passive mobilization. Methods: Fifty fingers in 38 patients with flexor tendon repair in zone 2 were enrolled in this trial. The patients randomly assig...
