PEREIRA, Sebastián; VINDVER, Gabriel  e  BIDOLEGUI, Fernando. Tratamiento con clavo endomedular de las fracturas metafisarias proximales y distales de tibia: Abordaje pararrotuliano medial en posicion de semiextension. Rev. Asoc. Argent. Ortop. Traumatol. [online]. 2020, vol.85, n.2, pp.99-106. ISSN 1852-7434.

Objective: To review the results of a series of metaphyseal tibial fractures treated with intramedullary nailing (IMN) in a semiextended position using a medial parapatellar approach. To report reduction quality, bone consolidation, range of motion (ROM) and postoperative knee pain at final follow-up. Materials and Methods: Twenty-three metaphyseal tibia fractures were treated with IMN. Twelve were distal tibial fractures (AO/OTA 43A), nine were proximal tibial fractures (AO/OTA 41A2/3), and two had segmental tibia fractures (AO/OTA 42C2). The minimum follow-up was 1 year. Results: Radiograph angulation at the fracture site was <5 degrees. All patients achieved bone healing. One patient (AO/OTA 42C2) required plate augmentation and bone autografting. Twenty-one out of 23 patients had knee pain scores of >20 according to the Lysholm scale. Conclusion: The parapatellar approach in a semi-extended position is a safe and useful technique for IMN of metaphyseal tibia fracture with no associated increased postoperative knee pain.
