Researchers in India have developed an intramedullary nailing method for the treatment of spiral and comminuted metacarpal fractures they claim is cosmetically appealing while providing stable fixation and avoiding periosteal stripping with a low complication rate.
In a retrospective, observational cohort study, the researchers treated 21 patients with 22 fractures via closed, fluoroscopically assisted, intramedullary K-wiring and a specially designed locking pin for proximal locking. Radiological testing was used to evaluate results, with range of motion, extensor lag, time to healing, amount of collapse, angulation, rotation and complications all being taken into account.
With an average follow-up of 14 months, the researchers reported all fractures healed uneventfully with an average of 8 weeks being needed for union. Metacarpal shortening averaged 2.04 mm, with a 4.81° average fracture postoperative angulation.
“Other than extensor tendinitis in two patients, there were no complications,” the authors noted.
