  • Title: Pediatric and adolescent tibial eminence fractures: arthroscopic cannulated screw fixation.
    Author: Reynders P, Reynders K, Broos P.
    Journal: J Trauma; 2002 Jul; 53(1):49-54. PubMed ID: 12131389.
    Abstract:
    BACKGROUND: Fractures of the intercondylar spine of the tibia are enigmatic injuries. The mechanism of injury remains obscure, and appropriate treatment is unclear. METHODS: The authors analyzed a series of 26 cases of displaced fractures of the intercondylar eminence of the tibia treated with an arthroscopically placed, intrafocal screw with spiked washer. The patients were reviewed after a minimum follow-up of 24 months and a maximum of 8 years. RESULTS: Sixteen patients had a type II tibia eminence fracture according to Meyers and McKeever (mean age, 15 years; male/female ratio, 11:5). Ten patients had a type III tibia eminence fracture (mean age, 17 years; male/female ratio, 1:1). We encountered neither stiffness nor iatrogenic chondral abrasion. Only three patients with type II had no laxity. The 13 other patients in this fracture group had a minor laxity without correlation with the clinical result. In four patients with a type III lesion, a residual laxity without functional deficit was noticed. In two cases with a type III lesion, a reconstruction of the anterior cruciate ligament was necessary 3 years after trauma. In four patients with a type III fracture, the fragment remained elevated, with minor impairment of the mobility (extension lag). No mechanical failure or infection was seen in this series. CONCLUSION: The authors found the intrafocal screw fixation for displaced fracture of the intercondylar eminence to be a reliable and safe technique, although complete restoration of the anteroposterior knee stability was seldom seen.
