Background:
Reconstruction of continuity defect of mandible is challenging, and there has been a lot of advancement in this field with variety of options for restoration. However, choice often becomes restricted in resource limited settings due to lack of trained manpower, time, infrastructure, supply of graft materials, etc. In this context, we aim to test the reliability of Kirschner wire (K-wire) with adaptation of looped-end for immediate interim reconstruction of continuity defect of mandible.
Methods:
Retrospectively, medical records of 10 years data were reviewed to include 22 patients who underwent immediate interim reconstruction of mandible with K-wire with looped-end adaptation for continuity defect of mandible. Data regarding patient demographic, type and length of mandibular defect, diameter of the wire and complications were recorded.
Result:
Among 22 patients within a follow-up period of 1-60 months (median 7.5), complications developed in 7 (31.8%) patients. Three patients (13.6%) had major complications which required interventions, and 5 patients (22.3%) with minor complications were managed conservatively. Total wire removal in our study is only 9%, which is lowest among the reported literature, migration or extrusion through bone was nil, and overall aesthetic and functional result was good in majority except few where either wire had to be removed or got deformed.
Conclusion:
Kirschner wire (K-wire) should be considered in resource limited setting as an immediate interim reconstructive method of mandible for being cheap and widely available. Our technique of looped-end adaptation results in better stabilisation leading to less removal rate, migration or extrusion.
