ABSTRACT
Objective
Hallux sesamoid injuries are well described and can be debilitating and chronically disabling. The role of orthobiologics such as platelet-rich plasma (PRP) in sesamoid injuries has not been reported. This study describes three cases of recalcitrant hallux sesamoid injuries in teenage athletes who returned to impact activities, pain free, following one treatment of PRP.
Methods
This is a case-series study describing three teenage athletes presenting to a tertiary level pediatric sports medicine practice with chronic hallux sesamoid injuries.
Results
The three patients (two female, one male) described in this case series were 13-, 16-, and 17-year-old athletes. Their primary sports were ballet, basketball, and Irish step dance, respectively. All three athletes received PRP: two received unilateral treatment (one tibial sesamoid, one fibular sesamoid) and one received treatment to bilateral tibial sesamoids. The average duration of symptoms prior to PRP was 52.5 weeks (14–128 weeks). The average time out of their primary sport was 48.7 weeks (20–78 weeks). Three of the 4 sesamoids treated with PRP were tibial sesamoids. Each site of injury was treated with one treatment of leukocyte-rich PRP. All three athletes were cleared to return to impact activities such as running and jumping at 6–9 weeks following PRP, specifically 9 weeks after the final PRP injection for the patient who underwent bilateral treatments.
Conclusion
In the three cases provided of sesamoid injuries treated with PRP, the time to return to impact activities was less than reported for athletes not treated with PRP. Acknowledging that other management factors likely contributed to return to impact activities, this case series sets the groundwork for future research investigating the role of PRP with needle fenestration in the treatment of sesamoid injuries.
