Mechanical Properties of Various Circumferential Tendon Suture TechniquesFrom the Department of Orthopaedic Surgery, Washington University School of Medicine, St Louis, Missouri, USA Correspondence: Paul R. Manske, MD, Department of Orthopaedic Surgery, Washington University School of Medicine, One Barnes Hospital Plaza, Suite 11300, St Louis, MO 63110, USA. We evaluated the mechanical properties of six different circumferential tendon sutures with a variable number of suture strands. Seventy-two human cadaver flexor profundus tendons were cut and repaired using only a 6/0 polypropylene circumferential suture. The six running suture techniques were: Simple; Simple-locking; Lembert; Halsted; Cross-stitch; Lin-locking; using 10, 14 and 18 suture passes. The increased suture passes increased both tensile and gap strengths. The tensile strength of the Lin-locking technique (29 to 63 N) was significantly stronger than the others, followed by Cross-stitch (27 to 38 N), Halsted (21 to 27 N), Lembert (20 to 27 N), Simple (11 to 22 N) and Simple-locking (10 to 17 N). The gap strength values were between 3 to 14 N, with no significant differences between the techniques. The resistance to gliding, as measured by work of flexion, was not affected by the number of strands. However, the Lin-locking significantly increased the resistance to gliding (33-36%) compared to the other techniques (6-21%); there were no significant differences between these five techniques.
