About

Intramedullary headless screw fixation for metacarpal and phalangeal fractures

Full description

The most frequent fractures in the upper extremities are phalangeal and metacarpal fractures accounts about 40%, which follow distal radius fractures in order of frequency.

There are many methods of fixation of these fractures as plates and K-wires. Plate fixation is able to provide open reduction and stability for early range of motion with mixed clinical results. Reported complications include stiffness, fixed flexion contracture of the adjacent joints, soft tissue dissection, and extensor lag.

There are minimally invasive techniques, including the use of K-wires, lag screws, cerclage wiring, and external fixation that limit soft tissue dissection. These options have drawbacks of malunion, nonunion, infection, need for hardware removal, and stiffness.

Intramedullary headless screw fixation is an emerging alternative to K-wire or plate fixation of displaced and unstable fractures of the phalanges and metacarpals. The Intramedullary headless screw fixation is a new option that offers rigid stability, early active range of motion, and easy insertion. Due to the minimally invasive nature of this technique, patients will experience better results in terms of range of motion, return to work faster, and minimize complications.

Beck et al. reported 100% of patients achieved full radiological union with minor complication rate and full range of motion and early return to work with average 96% of grip strength.
