Unrecognized pediatric partial Achilles tendon injury followed by traumatic completion: a case report and literature review.

Achilles tendon ruptures are a relatively common athletic injury but are exceedingly rare in the pediatric population. We describe the case of a 10-year-old ice hockey player who experienced an Achilles tendon injury from a laceration to the posterior leg from a skate blade that led to a partial tendon laceration. This tendon injury was initially unrecognized despite an emergency department evaluation. The patient continued to complain of weakness and paresthesia after the skin laceration had healed. A traumatic dorsiflexion injury while running several weeks later led to a traumatic complete tendon rupture. The clinical, operative, and physical therapy records were reviewed to complete the history, treatment, and rehabilitation progress. The initial laceration injury had occurred 6 weeks before presentation, and the traumatic dorsiflexion injury had occurred 2 days before referral to an acute orthopedics clinic. Open repair was performed several days after the traumatic completion of the laceration, and the patient was immobilized in a cast for 5 weeks. The patient had weaned off crutches by 10 weeks postoperatively and had returned to some activities and light skating at 5.5 months. A full return to running and ice hockey had been achieved by 8 months postoperatively. The optimal repair for this injury has not been well established in published studies. We have concluded that laceration injuries have the potential to mask tendon injuries and that prolonged symptoms after a laceration should suggest occult pathologic features. Open tendon repair is a viable treatment option in the pediatric patient with Achilles tendon ruptures. A return to activities within a reasonable period can be expected with robust physical therapy.
