Treatment of complex proximal interphalangeal joint fractures using a new dynamic external fixator: 15 cases.

The management of proximal interphalangeal joint fractures of the fingers is difficult. Dynamic traction splinting systems are cumbersome and the Suzuki fixator does not prevent secondary fracture displacement. Fifteen cases were treated with a new dynamic external fixator with distraction, the Ligamentotaxor. In two cases, additional fixation was required with a screw. After 10 months, grip strength scored 85.7% compared with the contralateral hand, flexion achieved 76.3 degrees and the extension deficit was 19.6 degrees . The visual analogical scale pain level (VAS) was 1.9 and the Quick DASH score totalled 16.9. Revision treatment was needed for sepsis for one patient. A case of secondary fracture displacement was corrected in the outpatient clinic. Consolidation was achieved in all cases. In conclusion, despite imperfect outcomes for these complex fractures, we believe that the Ligamentotaxor technique is useful.
