Skeletal muscle laceration is a common injury. Repair of disrupted delicate tissue still clinical challenge for surgeons. A few different repair techniques have been reported. However, the best technique has not identified. The aim present study to compare biomechanical features in muscles identify most effective one.New Zealand white rabbits (2.5-3 kg) were euthanized and medial gastrocnemius isolated. completely transected with scalpels then repaired by 3 techniques, namely, (1) 2-strand mattress, (2) 4-strand Kessler (with epitendinous suture), (3) Mason-Allen. To measure suture performance, specimens mounted onto mechanical testing machine Instron 5543. loaded failure at constant speed 60 mm/min. Data collected from Merlin v5.31 software used compute properties each specimen.There was no significant difference mean maximum load group (15.5 N) Mason-Allen (13.2 N), whereas control (Mattress) (4.4 significantly smaller than other 2 groups. Moreover, stitches stiffest among 3. It noteworthy that mechanisms different: all pulled out longitudinally, transmitted across ruptures occur areas adjacent stitches, indicating weakest element testing.Both shown better compared group. Further be done effect these on regeneration scar formation an vivo model.
