Abstract:
Objective —To compare effects of the locking-loop
suture pattern (LLP) and 3-loop pulley (3LP) suture pattern for tenorrhaphy on the intrinsic vasculature of
the superficial digital flexor tendon (SDFT) of horses in vitro after surgery. Sample Population —16 forelimbs obtained from 8
mature horses. Procedure —Tenotomy and subsequent tenorrhaphy
was performed in anesthetized horses. Following systemic administration of heparin, horses were euthanatized
and the limbs were removed and placed under tension to load the flexor tendons. The intrinsic
vasculature was then perfused with a mixture of barium sulfate and water. Four-millimeter sections of the
SDFT were prepared for microangiographic analysis. Mean vessel density was calculated for each section
by use of a grid consisting of 1.5-mm 2 vascular
assessment squares (VAS). Comparisons were made among the control, LLP, and 3LP groups. Results —Mean ± SD vessel density was 3.11 ± 0.38,
1.47 ± 0.47, and 2.01 ± 0.63 perfused vessels/1.5 mm 2 for control, LLP, and 3LP groups, respectively.
Significant differences in vascular density were detected between the control and 3LP groups, control
and LLP groups, and LLP and 3LP groups. Conclusions and Clinical Relevance —Use of the
LLP and 3LP pattern has deleterious effects in vitro on the intrinsic vasculature of the SDFT. However, the
3LP pattern was less disruptive to the intrinsic vasculature, compared with the effects for the LLP. Use of
the 3LP tenorrhaphy suture pattern in clinical situations may result in less damage to the intrinsic vasculature
of the SDFT of horses during convalescence. ( Am J Vet Res 2004;65:279–282)
