Introduction: proximal one-third of tibial fractures are fairly commonly seen nowadays. Their geometry makes them prone to
angular deformities. The use of a Poller or Blocking screw along with an intramedullary nail helps in avoiding these angular deformities and malunion. In this study, we aim to evaluate the functional and radiological outcomes of proximal one-third fractures
of tibia managed with an intramedullary nail and a Poller screw.
Material and Method: This study was conducted between 2017-2019 and a total of 14 patients were operated and followed up.
Their demographic, pre and postoperative data were recorded and assessed. For functional outcomes, the knee range of motion
and Rasmussen functional scoring system was used.
Result: The mean union time was 9.8 weeks and 3 cases had <5° of varus, 10 cases had<5º valgus, and 1 patient developed
varus of +7.08o. Rasmussen’s Functional Scores were excellent or good in 71% of patients. Superficial wound infection was
seen in 1 patient who subsided uneventfully.
Conclusion: Use of Poller screw is very effective in the prevention of angular deformities in case of proximal one-third fractures
of tibia managed with intramedullary nailing.
