An accessory bone, or os intercuneiform, in the foot caused pain and swelling. Surgical removal of the os intercuneiform provided symptomatic relief for the patient.
Area of Science:
- Orthopedic Surgery
- Anatomy
- Podiatry
Background:
- Accessory ossicles in the foot are common anatomical variations.
- The os intercuneiform is a rare accessory bone located between the navicular and cuneiform bones.
Observation:
- A patient presented with dorsal left foot pain, tenderness, and swelling.
- Imaging revealed an accessory bone, identified as an os intercuneiform, situated between the tarsal navicular and intermediate cuneiform.
Findings:
- Perioperative examination confirmed a synfibrotic connection between the os intercuneiform and adjacent tarsal bones.
- Conservative treatment options failed to alleviate the patient's symptoms.
Implications:
- Surgical excision of the symptomatic os intercuneiform resulted in complete postoperative pain relief.
- This case highlights the importance of considering accessory ossicles in the differential diagnosis of foot pain.
