Introduction: Thumb interphalangeal joint dislocations, although rare, have a significant impact on grip function. In case of irreducible dislocation, the interposition in the volar plate complicates immediate reduction. Open-air interventions are then necessary to allow a solid repair and rapid recovery.
Observation: We report the observation of two young patients who presented with open thumb trauma in whom after clinical and radiological investigation, the diagnosis of irreducible dislocation was retained.
Results: One year postoperatively, patients were clinically evaluated and showed a significant reduction in pain as well as full recovery of movement, strength, and functional abilities.
Discussion: Pure open dislocation of the interphalangeal joint of the thumb is rare, with cases of irreducibility often reported. Anatomic factors such as the volar plate and flexor pollicis longus interposition may contribute to irreducibility, as can the presence of an imprisoned sesamoid bone. Although cases of irreducibility associating these three lesions are rare, their management varies between authors, with some recommending repair of the ligament complex, while others opt for immobilization after reduction, depending on the stability of the ligament. joint.
Conclusion: Thumb interphalangeal dislocations are uncommon, and open cases are even rarer. Immediate reduction is often difficult due to irreducibility, thus requiring surgical intervention to achieve optimal functional recovery.
