Abstract
Ligamentous injuries of the hallux are rare, and when seen, they are most commonly treated conservatively. Surgical treatment of such injuries is also rare, making reports on the postoperative outcome and complications even less frequent. A case report of a hallux interphalangeal joint (IPJ) lateral collateral ligament tear in a 16-year-old gymnast is presented. Initially, she presented to the clinic with pain in her left hallux. She injured her toe while doing a gymnastic maneuver in which it got stuck and hyperextended. Physical examination revealed pain in her left great toe metatarsophalangeal and IPJs. Her medical history included the diagnosis of Ehlers-Danlos syndrome. She was managed conservatively with a controlled ankle motion boot for 4 weeks. When she returned for follow-up, her physical examination showed increased laxity to the great toe IPJ lateral collateral ligament compared with the other foot. A left foot MRI was done, which showed a complete rupture of the IPJ lateral collateral ligament origin (Figure 1). She underwent surgical intervention 6 weeks following her injury, in which the collateral ligament was repaired with suture anchors along with IP joint pinning to protect the repair (Figure 2). Following surgery, she returned to the clinic because of persistent drainage from a small hole near the incision site. During further incision and débridement, we discovered granulomatous tissue surrounding an embedded suture. The suture was removed, and the wound was irrigated. Following this procedure, the patient recovered fully in 3 weeks. She was provided a home exercise program and returned to gymnastics without limitations, toe pain, or instability. This case demonstrates an interesting complication following collateral ligament repair in the hallux.
