Background:
Checkrein deformity is a dynamic flexion deformity of the great toe, most often occurring after distal tibial trauma due to flexor hallucis longus (FHL) tethering or contracture. This report presents a rare case of post-traumatic checkrein deformity managed successfully with endoscopic FHL tenotomy.
Case Report:
A 16-year-old male presented with dynamic hallux flexion deformity, 3 years after internal fixation for a distal tibia and fibula fracture. Clinical examination confirmed checkrein deformity. Endoscopic FHL tenotomy was performed via hindfoot endoscopy. Postoperatively, the deformity resolved, and the patient achieved full function with no recurrence at 6 months.
Conclusion:
Endoscopic FHL tenotomy is a safe, effective, and minimally invasive technique for treating checkrein deformity, even in delayed presentations.
