Abstract
Bicondylar coronal plane fracture, eponymically named Hoffa fractures, is an extremely rare injury. We present a case of isolated unilateral bicondylar Hoffa fracture that was successfully treated with open reduction and internal fixation using headless compression screws with satisfactory results. We inserted posteroanteriorly oriented Acutrak screws perpendicular to the fracture plane via lateral parapatellar arthrotomy, which provided excellent compression across the fracture.

We describe a case of bicondylar Hoffa fracture that was successfully treated with headless compression screws
Six Acutrak 4/5 headless compression screws (Acumed, Hillsboro, OR, USA) were inserted over the 1.4 mm Kirschner wires in the deep flexion position at the posterior articular surface directing anteriorly perpendicular to the fracture plane to compress the fractures (Figure 4)
Conservative treatment of displaced Hoffa fracture with plaster cast was reported to lead to nonunion [8] or deformity, joint contracture, and subsequent osteoarthritis [15, 16]
Summary
Isolated coronal plane fractures of the distal femoral condyle, originally described by Hoffa [1], are rare, representing only 0.65% of all femoral fractures [2]. The eponymically named Hoffa fracture usually involves a single femoral condyle, most commonly the lateral femoral condyle [2, 3]. Bicondylar involvement is extremely rare, and, to the best of our knowledge, only 11 cases have been reported far in the English literature [4,5,6,7,8,9,10,11,12,13]. We describe a case of bicondylar Hoffa fracture that was successfully treated with headless compression screws
