What is the standard of care for lesser metatarsal neck fractures with joint dislocation?

• A. Open reduction and internal fixation (ORIF)
• B. Closed reduction and casting
• C. External fixation
• D. Percutaneous pinning

Answer: (A)

When a lesser metatarsal neck fracture is accompanied by a dislocated metatarsophalangeal joint, the key issue is restoring and maintaining a accurate articular fit while stabilizing the fracture. Open reduction and internal fixation provides direct visualization to anatomically reduce both the fracture and the joint, and then rigid fixation with screws or a small plate preserves that alignment through healing. This approach minimizes the risk of malunion, joint incongruity, and subsequent arthritis, and it also allows earlier motion to prevent stiffness. Closed reduction and casting often cannot maintain alignment in the presence of a dislocated, intra-articular injury, so the reduction may be lost and the joint surface remains incongruent. External fixation is usually reserved for cases with severe soft-tissue damage or polytrauma where definitive fixation isn’t feasible, rather than as the standard treatment for this scenario. Percutaneous pinning alone lacks reliable restoration of the articular surface and stability needed for a dislocated metatarsal neck fracture, so it’s not the preferred choice here. Therefore, open reduction with internal fixation is the best approach to restore a stable, congruent MTP joint and proper metatarsal alignment.
