Article title

Biomechanical Study of Two Peripheral Suture Methods on Repaired Tendons

Flexor digitorum tendon injuries are challenging
conditions to manage to ensure optimal patient outcomes.
While several surgical approaches with high success rates
have been developed, there remains no gold standard for
suture technique for the repair of flexor tendon injuries.
In this study, we compared two distinct peripheral suture
methods on the strength of repaired tendons. Pig flexor
digitorum profundus tendons were used in biomechanical
studies and the biomechanical influence on tendon repair
of continuous running peripheral suture (CRPS) and
continuous locking peripheral suture (CLPS), were compared,
using stitch length ranging from 1mm to 5mm. In
CRPS, the 1mm stitch length group displayed the highest
maximum load and breaking power, which was 1.57 fold
higher than the 2mm stitch length group. Pairwise comparison
revealed that the 1 and 2mm groups were statistically
different from the 3, 4, and 5mm stitch length
groups while comparison among the latter groups was not
statistically significant. For CLPS, the 1mm group exhibited
consistently the highest maximum load strength and
breaking power, which was twice the strength displayed
by the 2mm group. Pairwise comparisons between groups
showed statistical significance. For future repairs of flexor
tendon injuries, 1mm stitch length is highly recommended
for simple peripheral suture.
