Working Diagnosis:
Osteochondral defect of the proximal phalanx of the right great toe with mild degenerative changes at the right first MTP with moderate underlying subchondral cystic change and edema
Treatment:
Orthopedics performed a right 1st MTP capsulotomy and debridement with a great toe proximal phalangeal curettage and local bone grafting.
Author's Comments:
Providers should be aware that x-rays may be normal in patients with an osteochondral defect. If pain continues after conservative treatment and there is a high index of suspicion for an osteochondral defect an MRI is the study of choice for further evaluation and staging.
Editor's Comments:
This is an interesting and uncommon cause of forefoot pain after trauma, and it is important to note that first MTP osteocondral defect may be a risk factor for hallux rigidus later in life.
