Functional Outcomes Following Pilon Fractures of the Middle Phalanx Managed with the Ligamentotaxor External Fixator.

Abstract

Background: The surgical aims in managing displaced intra-articular fractures of the base of the middle phalanx include early joint reduction, maintaining congruence and early mobilization. Achieving this can be a challenge. However dynamic external fixators offer a solution. The study aim was to evaluate the use and outcomes of the Ligamentotaxor external fixator in patients with such injuries.

Methods: A total of 12 patients were managed with this device and outcomes were assessed. All patients reached clinical and radiological union.

Results: An average range of movement to the proximal interphalangeal joint of 63° was noted along with an average end of care-cycle quick-DASH score of 9.1. Two patients developed pin-site infections.

Conclusions: The outcomes seen support the use of the Ligamentotaxor in the management of middle phalanx intra-articular fractures. It is simple to apply, potentially avoids the secondary complications of open reduction and gives reproducible results. However judicious patient selection is advised.
