Modified gastrocnemius splitting anatomic approach to the tibial plateau. Medium-term evaluation

Abstract

BackgroundPosterior tibial plateau fractures, including avulsion fractures of the posterior cruciate ligament (PCL) insertion, represent a challenge for the orthopedic trauma surgeon. These injuries have gained a new perspective both diagnostically and therapeutically after the regular use of multiplanar computed tomography. In the herein study, we describe the outcome of patients sustaining a tibial plateau fracture with posterior articular involvement treated by open reduction and internal fixation (ORIF) using our modified gastrocnemius splitting anatomic approach. MethodsThis observational retrospective descriptive study was conducted at Complejo Medico de la Policia Federal Argentina Churruca-Visca. All patients were treated by ORIF by our team through our modified gastrocnemius splitting anatomic approach, and followed-up for a minimum of 12 months. ResultsA total of 18 patients sustaining plateau fracture were treated by this approach. Satisfactory tomographic reduction with articular gap and/or step-off <2 mm was achieved in 16. The mean time to the return to activities of daily living was 192.2 days. ConclusionThe modified gastrocnemius splitting anatomic approach represents a good alternative for the management of tibial plateau fractures involving the posterior quadrants.
