Long-term Results after Restoring Flexor Tendon Injury in Children Younger than Age 10 Years

In regard to the rarity of pediatric tendon lacerations compared with the adult population, sparse knowledge exists. Published reports indicate that the incidence of “good” flexor tendon repair outcomes is low. This study aimed to determine the injury pattern and demographics of pediatric flexor tendon injuries over the past decade.
A retrospective chart review of all flexor tendon injuries between 2005 and 2015 was performed. Parameters reviewed included demographics, injury mechanism, repair technique, outcomes, and complications.
A total of 20 patients with a median age of 4 years and 4 months experienced 45 tendon injuries. The most common cause of injury was glass (n = 10), with the most common digit injured being the index finger (n = 8). Zone II had the highest number of injuries (n = 14). The modified Kessler core and peripheral running sutures technique were used in all primary repairs (n = 18). Using author designed evaluation system, 80% of patients experienced excellent recovery. Four patients had good results. Only one patient complicated with rupture necessitating further surgery that its final evaluation was excellent.
The outcome of restoring flexor tendon injury of children is satisfactory, and we recommend that.
