Abstract

Background: Injury of flexor sheath (zones 2 and 3) is the hardest tendon injury to cure. Treatment of the flexor tendon had evolved from the conventional 2-strand repair (modified kessler repair) to multi strand (4-strands or 6-strands) repair, Aim and objectives: to compare and evaluate the function outcome of 4-strands with two techniques (locked and unlocked) in flexor tendon repairs (zone 2- zone 3) of the hand as regard strength and gap, rupture rate, adhesion, joint stiffness according to DASH scoring and Total Active Motion (TAM) test, Patient and methods: This prospective study conducted on 30 patients (15 patients treated by 4-strands locked technique and 15 patients treated by 4-strands unlocked technique) at orthopaedic department at Al-Azhar University Hospitals, Results: There was a statistical significant difference among the two studied groups regarding DASH score, pain on loading, stiffness and weakness. There was no statistical significant variance among the two groups as regard repair time, TAM, cold Sensitivity and ability to performance of daily activities, Conclusion: Four strand cruciate locked repair technique is safe and effective method for repair of long flexor tendons of fingers of children. It was associated with better functional outcome, lower pain, lower complications and higher satisfaction score compared to unlocked repair technique.
