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.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
