Translated title:
Study of incorporation of the fascia lata allograft bridging of a rotator cuff artificial tear in a rabbit animal model.
Summary:
Purpose: Despite advances in surgical treatment options, large rotator cuff
(r-c) tears still represent a challenge for orthopaedic surgeons. The purpose
of this study was to evaluate the temporary and spatial histological
incorporation of fascia lata allografts, used for bridging artificially created
defects of the r-c.
Methods: Seventy - two rabbits were divided into two groups and a supraspinatus
tendinous defect was created. Half the rabbit population underwent repair only,
while in the other half the defect was bridged utilizing fascia lata allograft.
The animals were euthanized on 2,4 and 6 weeks post - operative. Half of the
specimens were evaluated histologically and the other half underwent mechanical
testing.
Results: There was an increased remodeling activity, fibroblastic ingrowth and
strong presence of collagen fibers observed at 6 weeks on both groups. A
gradually increasing mechanican strength was noticed by week 6 and an increased
ultimate force to failure was also found at the same time period. There was no
significant difference observed between the two groups regarding their
histological and mechanical properties.
Conclusions: In the difficult scemnario of a large irreparable tear where the
simle suture of the remaining rotator cuff is impossible, allograft bridging,
could be used with satisfactory results.
