Insertion of intramedullary nails from the suprapatellar pouch for proximal tibial shaft fractures. A technical note

Intramedullary nailing of proximal tibial fractures can be difficult when using the standard entry portal. We evaluated the suprapatellar portal, using a midline quadriceps tendon incision, to perform intramedullary nailing of the tibia. Seven patients were treated with this adaptation of the standard intramedullary nailing procedure. An arthroscopy was done before and after the nailing procedure. No special equipment was used to perform the intramedullary nailing. We evaluated the handling and necessary modifications of the standard intramedullary technique to introduce the locked tibial nail through the suprapatellar approach. We found this technique not necessarily more difficult than the standard intramedullary nailing of the tibia through the infrapatellar entry portal. Although the patients did not complain of patellofemoral discomfort after the suprapatellar nailing, definitive scuffing of the cartilage in the lower part of the femoral trochlea was visible.
