Ex Vivo Strength Comparison of Bioabsorbable Tendon Plates and Bioabsorbable Suture in a 3‐Loop Pulley Pattern for Repair of Transected Flexor Tendons from Horse Cadavers

Abstract

Whereas in vivo testing is required, a bioabsorbable tendon plate may provide initial increased strength to support tendon healing and decrease external coaptation requirements.

Ex‐VivoEvaluation of a Modified Teno Fix®Device Repair Pattern Versus a 3‐Loop Pulley for Repair of Equine Flexor Tendons

“…To reduce these complications, repairs are often supported by prolonged external coaptation . However, additional complications can develop as a result of cast application, including cast sores, loss of bone density, decreased muscle strength, and tendon laxity . In addition, prolonged cast application inhibits early controlled movement of the tendon postoperatively, potentially resulting in adhesion formation.…”

“…Repair techniques developed for equine tenorrhaphy include suture patterns, autologous tendon grafts, bioabsorbable implants, and bioabsorbable plates . Investigation of intratendinous devices for equine tenorrhaphy is limited .…”

An Ex Vivo Biomechanical Study Comparing Strength Characteristics of a New Technique with the Three‐Loop Pulley for Equine Tenorrhaphy

“…Techniques include the single, double, and triple locking loop, the Bunnell, and the 3‐loop pulley patterns. Autologous tendon grafts combined with suture techniques have also been evaluated, 7 as have bioabsorbable implants and plates 11–13 . To date there is no combined suture material–repair technique described in vivo that prevents gap formation, even with external coaptation of the lower limb 4–6 …”

“…The strongest experimental repair method reported for equine flexor tendons, based on in vitro methodology, was the combination of bioabsorbable tendon plates sutured with size 2 polydioxanone (7 interrupted full‐thickness sutures), where failure occurred at 1500 N 13 . Previously the 3‐loop pulley with size 2 nylon 14 or double braided 3‐0 polydioxanone 10 had the strongest loads reported at 32 kg (313 N) and 155 N, respectively.…”

Propriedades mecânicas de dois padrões de sutura e dois tipos de fios aplicados às tenorrafias dos equinos

“…Ruptured flexor tendons require immediate surgical intervention with apposition of the tendon edges for adequate healing (Moraes et al, 2002;Moraes et al, 2003;Jenson et al, 2005). Several complications have been described, including suture dehiscence, necrosis of the tendon edges or severe infection (Hataka et al, 2000, Moraes et al, 2002Crowson et al, 2004).…”
