Pediatric Both-Bone Forearm Fracture with Flexor Digitorum Profundus Entrapment Causing Pseudo-Volkmann Contracture: A Case Report.

CASE: A 10-year-old boy presented with mechanical flexion contractures of the little, ring, and middle fingers after a both-bone forearm fracture surgery. Despite initial rehabilitation, he was unable to extend the fingers actively or passively in a neutral or extended wrist position, although extension was possible with wrist flexion, suggesting tendon entrapment. Surgical exploration revealed flexor digitorum profundus (FDP) entrapment at the radial fracture site. Surgical release provided immediate resolution of finger contractures.

CONCLUSION: This case demonstrates that FDP entrapment can occur at the radial fracture site and may involve multiple digits, representing an atypical presentation of pseudo-Volkmann contracture.
