Question 1

Cocca
Interlocking Horizontal Mattress Epitendinous Suture
VCOT 2020

Answer 1

3 loop pulley & Interlocking Horizontal Mattress epitendinous suture
~yield and failure force sign greater than 3LP alone
~fail though suture breakage

3 loop pulley
~fail with suture pull through

Question 2

Eby
Flexor Tendon Lacerations
VetSurg 2021

Answer 2

Epitendinous Suture
~peak & failure loads greater
~Loads to generate 1 & 3 mm gap greater
~failed by suture breakage

Locking loop alone
~fail by pull through

Question 3

Duffy
Flexor digital lateralis graft to Gastroc
VetSurg 2020

Answer 3

3LP and Flexor digitorm lateralis
~yield and failure force greater than 3LP
~No Gap formed
~75% failed by tissue rupture at myotendinous junction

Question 4

Duffy
Epitendinous Suture Placement
VetSurg 2020

Answer 4

Partial circumferential < Complete Circumferential
~mean yield loads
~peak loads
~failure loads
~force to create gaps

Failure
Circumferential: suture pullout
Partial: suture breakage

Clinical significance: Complete circumferential ES is recommended over partial ES placement.
